Measured on real domains over real certificates, Remark42 on one registrable
domain and the host page on another, with a control cookie behind every
blocked column so a run that blocks nothing cannot report a pass.
Three results the manual did not carry. Safari blocks third-party cookies out
of the box, so AUTH_SAME_SITE=none on its own has already stopped working
there, which makes the old recipe broken today and not deprecated later.
Firefox reaches a working session by a weaker route than Chrome and Safari do:
it accepts the server's attribute-less cookie, and because that cookie is
HttpOnly the browser then forbids the widget's script from replacing it, so the
session rides on an ordinary unpartitioned third-party cookie even with the
header flag on. And Firefox's block-all setting discards partitioned cookies
too, so no configuration survives it.
Two parameter descriptions were wrong in ways that matter here. AUTH_SAME_SITE
default emits no SameSite attribute rather than Lax, which is precisely what
lets the widget's own cookie land on Chrome and Safari. And AUTH_TTL_COOKIE
does not govern the cookie that carries the session under the header flag,
since the frontend hardcodes 200h to mirror the default.
TestRest_securityHeaders and TestRest_frameAncestors both start a server, read
one response, and then call teardown() partway through the test to start a
second server with different options. The first response body is only closed by
a defer, which does not run until the test returns.
httptest.Server.Close waits on connections still in use, so it blocks on a body
that will not be closed until after it returns. The tests deadlock and the whole
rest/api package dies on the timeout rather than on an assertion.
CI pins go 1.25, where the responses are small enough that the connection goes
back to the pool on its own and nothing hangs. On go 1.27 both tests hang, which
is how this surfaced.
Close the body and the client's idle connections before teardown() in both.
The opening summary said Telegram, Email and anonymous auth "would work
everywhere". That holds only with AUTH_SEND_JWT_HEADER set, and the widget's
own cookie is Secure, so the path is HTTPS-only and bounded by ALLOWED_HOSTS
besides. The sentence now states those conditions. What happens without the
flag is two separate things, whether sign-in succeeds in the frame and whether
it survives a reload, and the body below already separates them.
The other two are older: a stray backtick after "work on any domain", and
"expect" for "except" in a bullet whose neighbour already says except.
Related to #2218
* Document what actually keeps a cross-domain reader signed in
The separate-domain manual tells operators to set ALLOWED_HOSTS and
AUTH_SAME_SITE and says authorisation then works anywhere. That stopped being
true as browsers began blocking third-party cookies: the server-set auth
cookies carry no Partitioned attribute, so a browser enforcing the block drops
them whatever their SameSite value. What survives is AUTH_SEND_JWT_HEADER,
where the token returns in a header and the widget writes its own partitioned
cookie from inside the frame, and the manual never mentioned it. It now does,
with the XSS trade-off and a pointer to the parameter page, and it says plainly
that this rescues Email, Telegram and anonymous but not oAuth.
The parameter page's own mitigation list was left wrong by #2197. It promised
SameSite=Strict cookies and a __Host- prefix on HTTPS; authCookieOptions drops
the prefix entirely and uses SameSite=None; Secure; Partitioned whenever the
widget is embedded on another domain, which is the case the flag exists for.
* Say that the JWT header is sent in addition to the cookies, not instead
Both the flag's own help and the parameter table said the header replaces the
server-set cookie. Service.Set does neither: it writes the header and then
falls through to set both cookies, with a comment saying the cookies are needed
because headers do not survive the OAuth redirect. An operator reading either
description would expect the server to stop setting cookies once the flag is
on, and would misjudge what the flag changes about their exposure.
* Correct three details in the cross-domain documentation
The link to the parameter page used Zola's @/ syntax, which Hugo emits
literally as a relative href since there is no render-link hook. It was the
only such link under site/content; the other manuals use the relative form and
this now does too.
The CHIPS description claimed Partitioned makes the cookie unreadable from any
other page the browser visits. The partition key is the top-level site, so a
different site gets a separate cookie while pages and subdomains under the same
site share it. Overstating isolation on the page an operator reads to weigh
risk is the wrong direction to be wrong in.
And Chrome does not block third-party cookies by default: Google's April 2025
position keeps ordinary Chrome on user choice and names Incognito as the mode
that blocks. Naming Safari, Chrome Incognito and browsers configured to block
them says the same thing and stays true.
* Drop AUTH_SAME_SITE from the recommended cross-domain recipe
Measured rather than reasoned, because it reverses guidance this page has
carried for years. With only the remark42-https service taken back to the
default, both reload cases pass for anonymous and email, under a permissive
browser and under one enforcing partitioning.
The cookie jar after an anonymous sign-in says why. With the setting there are
four cookies: the server's unpartitioned JWT and XSRF-TOKEN, and the widget's
own partitioned pair. Without it there are two, the widget's pair alone, and
the session behaves identically. So the setting is doing something real, which
is what makes the passing run meaningful, and what it does is add an
unpartitioned HttpOnly JWT delivered as a third-party cookie to every listed
domain wherever the browser still permits that. Nothing needs it.
It stays documented for the configuration that does need it, which is one
without AUTH_SEND_JWT_HEADER, where the server's cookies are the only ones
there are.
One prediction the experiment falsified: the attribute case was expected to
fail on the default server-set pair. It passes, because a cross-site Set-Cookie
lacking SameSite=None is refused outright, so that pair is absent from the jar
instead of present with the wrong attribute. The manual now says so.
The test passed one strings.Reader as the body of both POSTs. client.Do
returns once the response headers arrive, and the import answers 202 before
the transport has finished copying the body, so the second http.NewRequest
reads the reader's Len to set ContentLength while the first request's
writeLoop is still advancing it. The race detector caught it on CI as a write
in strings.(*Reader).WriteTo against a read in NewRequestWithContext, failing
a test nothing had touched.
Reproduced in isolation to confirm the mechanism rather than infer it from the
trace: a handler that answers 202 without draining an 8 MiB body, two requests
sharing one reader, and -race reports strings.(*Reader).Len in
NewRequestWithContext against strings.(*Reader).Read on every run. It does not
reproduce in this package locally, which is why it reads as a flake.
Both requests now build their own reader over the same content. The second one
carries a full body where before it inherited a consumed one, which is closer
to what the case is about: a second import arriving while the first is running
still has to be refused.
deleteme.ts set __webpack_public_path__ to window.location.origin plus /web/,
which discards any path prefix the instance is served under. It is inert today
because that bundle references no asset and loads no chunk, so the value is
assigned and never read, but it is wrong by construction and would resolve at
the domain root the moment anyone adds an image to that page. Removing it
leaves webpack's own publicPath: 'auto', which derives the base from the
script's URL and is right in both arrangements.
Every service in the suite spoke http, and the browser gates a whole class
of behaviour on the page protocol: Secure cookies, SameSite=None,
Partitioned, and any code reading location.protocol. None of it was
executed, which is how setAuthCookie came to decorate its cookies with
__Host- on https pages and survive for years.
A TLS pair joins the stack: remark42 with SSL_TYPE=static on 8443, and an
nginx serving a host page on its own name on 8444, both on a self-signed
certificate that e2e/tls/generate.sh makes and .gitignore keeps out. Every
context accepts it, and so does the readiness client, since those are the
only servers either talks to. The instance also runs with
AUTH_SEND_JWT_HEADER, which is what makes the widget write cookies of its
own: without it the client-side writer never runs on any https page here
and every assertion about the attributes it chooses is vacuous.
Three cases. Signing in across origins and then reloading, which is the one
the http cross-origin case cannot make: the widget holds its token in
memory for the life of a page, so signing in and posting says nothing about
persistence and only the reload asks whether the cookie was delivered,
stored under a name the backend reads and sent back from a third-party
frame. The cookies themselves, read out of the browser store while the
widget is embedded elsewhere, since a cookie the browser refused is absent
from that list entirely and one it kept but will not send is worse than
useless: every copy of both names has to be Secure and SameSite=None, at
least one has to be partitioned, and none may carry a __Host- prefix
nothing on either side reads. And the same reload under a browser that
blocks third-party cookies, which the widget's own partitioned pair is the
only reason to survive.
That last one needs a browser playwright does not offer: its default
arguments disable ThirdPartyStoragePartitioning outright, so a run
configured wrongly keeps every third-party cookie and the case would pass
while asserting nothing. IgnoreDefaultArgs drops that list and re-supplies
it without the one feature, and a control cookie set from inside the frame
has to be refused before anything else is read, so a playwright release
that changes the list fails as itself instead of going quietly vacuous.
All three pass against master. What TLS still cannot reach, the OAuth popup
above all, is written down in the README.
The sign-in panel is positioned absolutely, so it grows the iframe without
growing the document: `useDropdown` measures the panel itself and posts the
sum, and a ResizeObserver on the panel keeps that number current while it is
open. Closing it resizes no box anything watches. The panel observer goes with
the element, and the document observer in `Root` sees nothing, because the
document height never changed in the first place. Nothing then tells the parent
to come back down, so the iframe keeps the open panel's height and the
embedding page carries a hole under the widget for as long as the reader stays
on it.
The effect's cleanup now reports the height, with no element, so the number is
the document's own. That is the one place both close paths reach: the click
inside the widget, and the clickOutside message the host page posts when the
reader clicks anywhere else.
TestGeometry_HeightFollowsTheAuthPanelAndTheTextarea covers this and has been
intermittently green: whether the frame comes back down without the fix depends
on timing, and it fails on every run here while CI has been passing. The unit
test fails with the cleanup reverted.
* Assert what the image endpoints promise rather than the compressor's output
Three tests pinned the exact bytes or the exact length of an encoded
image, so they fail on any toolchain whose deflate or png encoder emits
something different. CI pins go 1.25 and passes; go 1.27 fails all three,
while the images themselves are perfectly valid.
TestRest_QR now decodes both the golden file and the response and
compares the pixels, which is the same assertion about the qr code and
none about the encoder. The two resize cases assert the decoded image
fits the box resize was given and touches one of its sides, which is what
fitting to a box means and what the function actually promises.
Resolves#2200.
* Fill the instance URL into the embedded frontend at serve time
The widget falls back to a compiled-in URL whenever a page omits
`remark_config.host`. The bundler cannot know that URL, so it emits
`{% REMARK_URL %}` and each distribution substitutes it: the docker image
rewrites the files under its web root at container start, and the release
binary, which serves the build embedded in itself, had nothing doing it.
`prepare-release-assets.sh` filled the marker with `http://127.0.0.1:8080`
before the embed instead, so every copy of the binary shipped pointing at
the visitor's own loopback address, and on an https site the request is
blocked as mixed content besides.
It has been that way since v1.11.0, the first release to embed the
frontend, and the earlier binaries embedded none, so the tarball has never
served a correctly addressed widget.
The placeholder now survives into the embedded copy and the file server
fills it with the configured `REMARK_URL` as it serves, which is what the
docker image already does to its own copy. The image no longer bakes the
loopback address into its embedded copy either, so the fallback it keeps
for a missing web root is correct rather than misleading.
Substituted in html, js and mjs, the same set `docker-init.sh` rewrites,
and the served size is the substituted one so a response is neither
truncated nor left hanging.
Nothing exercised the marker the frontend build emits wherever the instance
url belongs. Every page in the suite sets `remark_config.host` from its own
origin, so the compiled-in fallback is never read, and a distribution that
stopped substituting would keep the suite green.
Two tests. The first reads the served bundles and pages back and asserts the
marker is gone from each and that what replaced it is this instance. The
second covers what the substitution is for: the widget document carries no
host of its own, since `iframe.html` builds its config from a query string the
parent never puts one in, so everything it requests is addressed with the
compiled-in url. It asserts the widget renders and that the config request
went to this instance.
The demo pages cannot show the second. Their loader builds the bundle's own
script url from `remark_config.host`, so a page without one never gets as far
as loading the widget.
Verified by disabling both substitution paths, the serve-time one and the
docker image's, and rebuilding: both tests fail. Editing the files on disk is
not enough, since the file server substitutes as it serves.
The served body now depends on remarkURL, but cacheControl builds its
etag from version and path only. An operator who notices the widget is
addressed to the wrong host, corrects REMARK_URL and restarts the same
binary gets 304 on revalidation, so the client keeps a bundle pointing
at the old host. Cache-Control is no-cache, so it revalidates every time
and never ages out of that state either.
That is the exact situation this substitution exists to fix, so the
validator has to carry the url.
* Drop the frontend workspace root and re-resolve the lockfile
`frontend/` carried a `package.json`, a `pnpm-workspace.yaml` and the lockfile
for a workspace of exactly one package. Two manifests meant two places to
declare a version, and the app pin was the one that did not win: `preact` and
`@babel/core` were each written twice, and a bump to the app manifest alone
would have been a silent no-op, since `pnpm.overrides` decides and it lived at
the root.
Everything pnpm reads now lives in `frontend/apps/remark42`: dependencies,
`packageManager`, `engines` and the overrides. `frontend/` keeps `.nvmrc`,
`.husky` and `CLAUDE.md`, none of which pnpm reads. The directory nesting
stays: every path in the repository points at `frontend/apps/remark42`,
including the published contributing docs, so moving the package up would have
rewritten 14 files to no benefit.
Moving the manifest kept the old resolutions verbatim, which left optional peer
subtrees the tree no longer reaches: `ts-node` under jest, `@swc/core` under
webpack, `vitest` under `@testing-library/jest-dom`, `tslib` under
`webpack-dev-server`. None is referenced by any config or source file here.
Re-resolving drops 137 packages and moves 59 to versions already permitted by
the ranges in the manifest, 1446 to 1308, with no direct dependency changing
version: the five that look changed differ only in their peer suffix. Every
file `pnpm build` produces is identical in size before and after.
The frontend-deps stage of the Dockerfile sets `CI=true` so the `prepare`
script skips husky, which has no git repository to install hooks into there.
* Stop markdown-only changes triggering heavy workflows, and check the documented versions
`ci-backend.yml`, `ci-build.yml` and `ci-frontend.yml` all end their path
filters with `!**.md`. The e2e workflow did not, so a change to any markdown
file under `frontend/` or `backend/` matched its `frontend/**` and `backend/**`
entries and started a docker build and the whole browser suite. The release
filter had the same hole and two of its own: it names `README.md` and `LICENSE`
on purpose, since `.goreleaser.yml` packages both, so it now excludes markdown
under `backend/` and `frontend/` only. `CLAUDE.md` and the installation page
were listed as well, and neither is packaged.
`ci-site.yml` goes on matching markdown, which is right, since the site is
built from it. It excludes `CLAUDE.md`, so a future `site/CLAUDE.md` cannot
start a site build, and `site/README.md`, which documents how to build the site
rather than being part of it.
The installation page tells a reader that a source build needs Go 1.25, Node
24+ and PNPM 10. Nothing kept those in step with `backend/go.mod`,
`engines.node`, `packageManager` and `.nvmrc`, and the drift is silent: a wrong
version in the docs builds and tests exactly as well as a right one. `.nvmrc`
is the pin with form here, having sat at 16 through the whole node 20 migration
because nothing red ever pointed at it. The check compares each stated version
against its source and holds `.nvmrc` to `engines.node`, and it fails when the
page states no version at all, so removing the claims cannot turn it into a
check that passes by comparing nothing.
Its own workflow rather than a step in an existing one, since the inputs span
the backend module, the frontend manifest and the site.
* Fix the cookie fallback page, asset path, message senders, auth teardown and cookies
Two defects with the same origin: 5825a55b, the January 2021 frontend
rewrite, first released in v1.7.0.
It removed the build entry for comments.html while leaving both the
template and the link to it in place, so the page the auth panel offers
when third-party cookies are blocked has been a 404 ever since, for
exactly the reader who has no other way in. The template needed no
changes; it is built again, and an e2e case now opens it on a thread
carrying a comment and waits for that comment, so the page being served,
its inline script running and it asking for the thread named in its own
query string are all covered. Against an image built without the plugin
entry that case fails on the 404, which is the regression it exists for.
It also fixed the public path to the domain root, so an instance mounted
under a prefix, which manuals/separate-domain documents, asked for
/web/google.svg when its own icons live under that prefix. Fifteen
provider icons in remark.mjs and one in last-comments.mjs. The path is
now derived from the url the bundle was loaded from, which is correct for
both arrangements, and the file loader no longer overrides it.
The host page also accepted postMessage from any window: every frame on a
page can reach window.parent, and the handler resizes the widget, scrolls
the page and opens the profile overlay. It now ignores anything that did
not come from a frame this module created.
A fourth, in the same family: the OAuth flow never tore its polling down.
`subscribed` was declared, checked and cleared but never set, so the guard
against a second subscription was dead code and every provider click
attached another listener pair. The five minute deadline then rejected
without unsubscribing, leaving those listeners and a retry that
reschedules itself for as long as getUser returns null. Cross-domain is
where getUser never stops returning null, so a reader on the arrangement
manuals/separate-domain documents was left polling /auth/user once a
minute for the life of the page, against a route capped at 2 req/s. It
also rejected with no argument, and the caller stores that as the error
state, so the interface had undefined to render. The deadline now tears
the subscription down and rejects with an error.
The message check had a second half. Hardening the parent left the widget
document trusting any sender, and it acts on signout and theme, so
anything holding a reference to the frame could sign a reader out.
`auth.hooks` already checked `event.source !== window.parent`; that check
is now a shared `isFromParent` and the three listeners that lacked it use
it too. The origin cannot stand in for it, since the host page is
whatever site embeds the widget and `ALLOWED_HOSTS` is enforced server
side through `frame-ancestors`.
And createInstance stacked its listeners. It reuses the marked iframe
instead of building one, but installed three listeners plus a title
observer on every call, while destroy could only reach the newest
closure, so a second call without a destroy stranded a set for good. The
listeners of the current instance are now detached before the next set
goes on. Reuse and the ignored config are unchanged: that contract is
open in the backlog note and not settled here.
The auth cookies the embedded case needs were not being delivered, in
both halves of the client's own writer. The name was decorated:
setAuthCookie prefixed with __Host- whenever the page was https, so a
real deployment wrote __Host-JWT and __Host-XSRF-TOKEN while the backend
looks for JWT and the fetcher reads XSRF-TOKEN, and nothing anywhere
reads a prefixed name. Nothing caught it because the prefix is applied
from the page protocol and every test and the dev server run on http;
there is now a second suite pinned to an https page, which is the only
condition that shows it. And the attributes could not be delivered: both
were SameSite=Strict, judged against the top-level site and not the
request's own origin, so a Strict cookie is never sent from a
third-party frame, which is the entire configuration this code exists
for. They now follow the embedding, Strict while the widget shares its
page origin and None with Secure and Partitioned once it does not, since
that is the only third-party form browsers still accept. Over http in a
third-party frame no combination works, and the strict form is written
instead of one the browser would reject outright.
That leaves the client half of #1877 working, whose reporter wanted
AUTH_SEND_JWT_HEADER for exactly this arrangement, and whose first half
merged as #1929. The server's own cookies still carry no Partitioned;
that is upstream work in go-pkgz/auth.
Two plan changes. A review pass corrected its central Path B premise,
which said the first document render is anonymous permanently, in every
configuration: it is anonymous in the configuration remark42 ships,
go-pkgz/auth exposing XSRFIgnoreMethods and remark42 leaving it unset.
The door is not shut, it is closed by a setting, and opening it is
scoped security work and not a flag flip, because GET /deleteme
deletes every comment a user has written and is a GET so the emailed
link works. And the separate-domain arrangement is promoted from a
constraint bullet to a named requirement with acceptance criteria, since
a test that signs in and posts without reloading passes while
persistence is entirely broken.
Review found a seventh, and it was reachable only because of the first:
comments.ejs built its title with innerHTML from the url query
parameter, so restoring the build entry made a reflected XSS live on the
instance origin, where the page is a top-level document, frame-ancestors
does not apply and the /web CSP allows unsafe-inline. The anchor is now
built through the DOM with textContent, and only http and https reach
href, since escaping alone leaves a javascript: url working. Two e2e
subtests pin both halves, and mutation testing separates them: restoring
innerHTML fails four assertions, while keeping the escaping and dropping
only the scheme guard fails the href one alone.
Review also found the poll teardown test did not exercise the poll.
handleWindowVisibilityChange is reachable only from the two listeners
and from the retry it schedules itself, and the test dispatched neither,
so no request was ever made and the assertion compared zero to zero; it
passed with the teardown reverted. It now dispatches focus, asserts
requests are being made and keep coming, and only then that they stop.
And the teardown could not cancel an in-flight getUser: a null resolving
after the deadline ran the code past the await and scheduled a fresh
retry with nothing left to clear it. A closure-local flag checked after
the await stops that, chosen over a second guard at the top of the
handler because only one of the two is detectable by mutation and this
is the one that prevents the stray timer rather than neutering it.
The inline handler in the iframe template accepted messages from any
window while acting on them through location.replace and document.title.
It now takes only the parent, the same check the host page side makes.
* Pin the published /web surface in the e2e suite
#2178 renamed the widget bundles from .js to .mjs and the URLs earlier
releases served under those names stopped resolving. Three were noticed
from the demo site; the rest, including every locale chunk, were found
only by requesting the whole surface of both images over HTTP. #2192
restored them with a server-side alias, and nothing in the suite would
have caught the break or would notice it returning.
Two cases with deliberately different criteria. The documented names are
written out, because the documentation decides that list and not the
build: an operator pastes privacy.html into an OAuth application, the
nginx manual proxies index.html by name, and the integration guides start
from the embed script. Everything else is taken from the build itself, so
whatever the bundler emitted has to serve identical bytes under its
legacy .js name and parse as a classic script, which is the premise
serving one under the other rests on. A third case requests a name that
does not exist, without which a fallback serving one page for everything
would keep the whole table green.
All of them check the content type as well as the bytes: nosniff is set
on every response, so a bundle served as text/plain is as broken as one
that 404s while comparing equal.
On e3d1d0e2, the commit before the alias, this fails with 32 red subtests.
* Cover the widget behavior the e2e suite never drove
Removing npm from the widget takes the jest tests with it, and everything
here was protected by jest or by nothing at all.
Signing out was untested at every level, and the panel repainting is the
half that always works: the assertion after the reload is the one that
catches a session the server never ended. The edit form has to hand back
the source that was posted and not the rendered comment, which #2040
shipped the other way round, taking every entity and tag the author had
written with it. A draft has to survive a reload and be gone once the
comment is posted. A refused comment has to stay in the form with
something said about it, so that case drives the backend's own
restricted-words code and then retries with the route removed.
Uploads had no browser coverage in either direction. The posted case
asserts naturalWidth instead of visibility, since a broken src still
renders as an empty box, and the failing case holds the intercepted
request long enough for the in-flight state to be observed: without that,
"the text is unchanged afterwards" would hold for an upload that never
started.
Moderation and reader-side hiding are asserted from a page other than the
one that made the change. Hiding seeds a second author, so it proves one
person is hidden and the thread not emptied, and both the blocked
author and the moderated one carry the run id in their names: a block and
a verification are properties of the user and outlive the run in the
stack's database, so a fixed name works exactly once.
Locales were the largest hole. Each catalog is a chunk fetched at
runtime, and loadLocale falls back to english on any failure instead of
throwing, exactly as an unrecognized name does, so every case compares
the rendered string against the file on disk. One case per catalog
covers that they are all served and render; another fetches one through
the widget document and asserts it parsed, which is the half a chunk that
serves but fails to parse would slip through. The delete page and the
last-comments stylesheet had no coverage of any kind.
Two things the suite itself needed. The widget's own aria-label is
translated, so commentFormSel only ever finds an english widget and a
localized case cannot use widget(). And the auth probe is capped at two
requests a second for the whole suite, hard-coded in rest.go: the added
cases pushed past it and the suite began manufacturing its own 429s,
which render as a signed-out widget and fail whichever test happens to be
signing in, so the pacing gap is wider and the locale cases stub the
probe they never needed.
* Harden the e2e harness against silent failures and stale stacks
Three things the suite could not tell you about itself.
A browser failure nothing asserts on now fails the test that caused it.
Uncaught exceptions are the ones worth the machinery: a widget throwing
while it renders leaves most of these cases green, since they assert on
elements the browser lays out either way. Rate-limit responses are
recorded as well as logged for the same reason. A test driving an error
path declares what it expects by substring, so a case that means to
break something says which thing.
The stack the suite adopts is now checked against the sources under
test. Every checkout builds the image tag the compose file names, so a
stack from another worktree, or from this one before an edit, answers on
these ports and passes every readiness probe while serving code nobody
is looking at. stamp.sh digests what goes into the image, compose passes
it as the revision label, and a mismatch is refused with what to do
about it. Checked after our own build too, or a stamp that never reaches
the image would be a guard that silently passes everything.
assertSignedIn no longer waits out the whole timeout on a refused status
read. /auth/ is capped at two requests a second for the entire suite, a
bare literal at rest.go:242, and a case signing in on two pages spends
that twice; when the read that repaints the panel is the one the limiter
turns down, the widget shows signed out over a session that exists and
no later request will ask again. The short first wait now ends in a
focus handoff, which the widget answers by re-probing, and only then
does the real wait run. A sign-in that genuinely failed still fails,
since the second read finds no state either. That is what
TestComment_AdminPinsAndVerifies and TestComment_BlockedAuthorCannotPost
were failing on in CI while passing locally.
signInAnon takes the page for that reason, and its callers pass it.
* Cover iframe geometry, the embed contract and five deployment modes
Seventeen cases for the parts of the widget that broke repeatedly and
that nothing here could see, plus the areas jest was the only check on.
Geometry is the biggest of them. The widget measures its own document
and posts the number for the parent to apply, and every way that has
gone wrong is invisible to assertions about elements, which read the
same whether the frame is right, twice too tall or a strip. So: the
first height the parent is given describes rendered content and not the
preloader, the frame matches the document it holds and does not stand
24px taller, no_footer leaves the last comment inside the frame, and the
frame follows the sign-in dropdown and the growing textarea and comes
back down again. Each was verified by reintroducing the defect it covers
and watching it fail: a 63px report before the real one, six pixels of
body padding, and a frame sized under the content.
The embed surface is the other half the widget cannot see. An element
placeholder gives way to exactly one iframe carrying the embed's own
marker, a second createInstance reuses it, destroy takes it away with
its handles, and a theme change after load reaches both the element and
the document. A page that posts a message of its own, which is all
embed.ts's own title observer does, no longer empties an open login
form.
Five configurations that cannot share an instance get one each, since
each changes the widget for every reader: an admin's unlimited edit
window, a session carried in a header and not a cookie, an instance with
no auth provider to offer, anonymous voting, and the notify module,
without which email_notifications is false and the subscribe control
never renders at all. The subscription round trip is the one place a
token from a real message is exchanged for state the server keeps.
Two things surfaced there and are left alone, both said so in place. The
panel confirming an unsubscribe cannot be observed, because the click
changes the step and the dropdown closes on an element no longer in the
rerendered view, which the component notes as its own awkwardness; the
case asserts the request and the answer, which is what decides whether
the reader still gets mail. And the widget takes the subscribed state
from user.email_subscription, absent from what it hydrates the user with
on the next load, so after a reload it offers to subscribe somebody who
already is.
simple_view needs no instance, being a query parameter, so both branches
run against the main one. A transient failure of the status probe has a
case too: the session belongs to the server, and one refused answer must
not end it.
The suite runs about four and a half minutes now, so the workflow's own
budget goes to 20m to match the Makefile, well inside the job timeout,
and the workflow stamps the stack it starts the way the Makefile does.
The locale case that loads the widget document directly is renamed for
what it protects, the origin and CSP its chunks are fetched under.
Telegram gets no test: the base URL is formatted inline inside
go-pkgz/auth, so nothing here can point it elsewhere, and the fix
belongs upstream in v1 and v2 both. Reported as #2208.
Three things CI found that a laptop cannot. The anonymous sign-in form
validates its input against pattern="[\p{L}\d\s_]+", and E2E_RUN_ID is
"<run id>-<attempt>" on a runner, so every username built from it
carried a hyphen the browser refused to submit: no request was made and
the case waited out its timeout on a panel that was never going to
change. Names are built by anonName now, which drops what the pattern
does not allow and adds the pid, so a second run against a surviving
stack does not meet its own blocked and verified users. signInAnon waits
for the request the submit makes, so the next such refusal fails as
itself.
The admin instance takes its admin from an email address, not a name.
remark42 hashes an anonymous id from the name and the client address
together, to tell apart two people picking the same name, so the id
written into ADMIN_SHARED_ID belonged to nobody on a runner and the
instance had no admin at all: the countdown stayed, and the backend
refused the edit. An email id is sha1 of the address, which is the same
everywhere.
The subscription case clears its own precondition and confirms through
the page's session. The dev user is shared and a subscription outlives
the run, so the panel opened on the subscribed step; and the panel moves
to that step while its token textarea is still on screen, leaving no
moment at which the control to submit it exists.
Three settings of remark_config get cases of their own, none having had
any: __colors__, which is the one setting that travels through
window.name and not the query string, so nothing else in the suite would
notice the path going; the url override, which is how a canonical
address keeps one conversation across pages that differ; and the
subscription controls an integrator turns off, with the both-shown case
as the control.
Writing the url case turned up a backend defect, reported as #2204 and
not fixed here: a thread url containing "&" cannot be commented on at
all. Sanitize runs the locator
through SanitizeAsURL, which round-trips it through bluemonday, so the
url is stored html-escaped; the bucket is created under the escaped key,
the read-back uses the real one and answers 500, and every later find,
count and feed asks for the real url and is told the thread is empty.
Any page addressed with two query parameters is affected. The case uses
a single-parameter url for that reason.
Five more from the same audit, none needing a service. Collapsing a
thread shrinks the frame, which every other geometry case would miss:
they all assert growth, and a widget that only grew would satisfy them
while leaving a hole under each collapsed thread. Voting gains the
direction nothing covered, downvoting and its survival of a reload, and
the rule the other vote cases work around, that your own comment offers
no buttons and the backend refuses the vote anyway.
A vote with the X-XSRF-TOKEN header stripped has to be refused. That
check is why a document navigation, an iframe src among them, is always
anonymous and why the widget hydrates its user over XHR, so anything
designed around that wants it pinned.
An unrecognized locale has to render English, which is loadLocale's only
observable guarantee: it falls back the same way for a name it does not
know and for a chunk it cannot fetch. And a comment's timestamp has to
be the reader's own, which is the one part of rendering that cannot move
to the server, asserted from a context in Kiritimati against the same
Intl the widget uses.
A host page on an origin the widget is not served from, which is the
separate-domain setup the manuals describe and the configuration readers
actually hit problems with. Every other host page here is served by
remark42 itself, so the cross-site path was never taken: an nginx on its
own name and port serves e2e/hostsite, and the case asserts the frame is
revealed, which means its document loaded and reported itself inited
across the origin boundary, and that the thread it renders is the one
the page's address names. Signing in is left out on purpose, an embedded
cookie needing SameSite=None, which browsers take only as Secure, and
this stack speaks http; that is #1139 and not something a case here can
settle.
The other half is ALLOWED_HOSTS. The no-provider instance names only
itself, so a page elsewhere embedding it is refused by the browser, the
document never runs, and the reveal comes from the widget's own fallback
five seconds later. Both directions are worth holding: without the
fallback a mistyped host leaves a permanently invisible widget with
nothing to say why, and without the refusal the setting does nothing.
The host page's title reaching the stored comment gets a case, the path
running the other way from everything else here: the page posts its
title into the widget, the widget sends it with the comment, and it is
what a feed and the admin listing show. Set after the widget is up, so
it covers the observer embed.ts installs and not the value read at boot.
max_shown_comments has no case. The setting reaches the widget, appears
in the iframe's query string and changes nothing: four comments render
with it set to two, which is #812, still open, where the reproduction is
now recorded. A case for it would be red on master.
The README gains what the suite cannot reach. Every service here speaks
http, so anything the browser gates on the page protocol is invisible: a
Secure cookie, anything keyed on window.location.protocol, and the
SameSite=None with Secure and Partitioned form that is the only one an
embedded frame can still use. That is not hypothetical, setAuthCookie
having decorated its cookies with __Host- on any https page and survived
precisely because nothing here runs on one. The cross-origin case names
the assertion to add if the stack ever gets TLS, which is the reload:
the widget holds its token in memory for the life of a page, so signing
in and posting without reloading passes while persistence is broken.
And the trap waiting for whoever acts on that: playwright's own default
--disable-features argument carries ThirdPartyStoragePartitioning, and it
beats both --test-third-party-cookie-phaseout and
--block-third-party-cookies passed through Args, so a run meaning to
prove the third-party case keeps an ordinary third-party cookie exactly
as it would with no flags at all. IgnoreDefaultArgs is the lever, and a
blocking run has to assert a control before anything it reports can be
believed. None of it reaches the widget's own storage fallback either:
IS_STORAGE_AVAILABLE stays true with partitioning enforced, chromium
partitioning localStorage instead of denying it, so comments.html needs
webkit and not a flag.
The downvote case now actually corrects. It claimed the score ends where
the second vote leaves it and never cast one, so #728, a reader taking a
vote back, could break with it green. It also turns out the opposite
vote takes the first one back instead of flipping it, so the score
returns to zero and never reaches +1, which is what the case asserts,
before and after a reload. Renamed for what it covers.
* Serve the legacy /web/*.js names from their .mjs siblings
The build emitted <name>.js alongside <name>.mjs until the two compilations
were collapsed into one. Dropping the second compilation was right, but it
removed URLs the project itself had published: the v1.16.4 SPA documentation
named /web/embed.js directly and its loader snippet requested .js. Pages that
hard-coded those names now 404 with no deprecation.
webFiles.Open retries a missing .js against the .mjs sibling. The bundles
contain no import or export, so the same bytes serve both names. The retry
runs only once both sources report the name missing, so a real .js still
wins, and an unreadable sibling reports its own error rather than being
flattened into the requested file's 404.
Related to #2178
* Reuse only the comments iframe embed created
createInstance took root.firstElementChild as its iframe, so anything a page
left inside #remark42 was adopted instead. A <noscript> fallback became the
"iframe", createIframe never ran, and the height messages went to an element
that cannot show comments.
That also defeats the placeholder support, which promises content in the root
is cleared once the iframe reports inited: a text placeholder works, but any
element placeholder is mistaken for the iframe, so inited never arrives and
the cleanup never runs.
The iframe now carries data-remark42-iframe and the lookup is scoped to a
direct child, so a second createInstance still reuses it while nothing else
in the root can be adopted.
Related to #1990
* Assert the backup contents rather than the compressed size
TestBackup_MakeBackup and TestBackup_Do pinned the gzip output at 52 bytes,
which ties them to the exact output of compress/flate. The same input encodes
to 57 bytes on go 1.27, so both fail for anyone building on a toolchain newer
than the one CI pins.
They now read the backup back and compare it against what the exporter wrote,
which is what the tests were reaching for and does not move with the
compressor. The payload is a shared constant so the two cannot drift.
`newPageOn` writes a trace into `traces/` when a test fails, and never created
that directory. It is gitignored, so a fresh checkout does not have it.
Traces were not in fact being dropped: the driver creates the parent of the
trace path itself, checked against the version this module pins rather than
assumed. The directory is created here anyway because nothing in the suite
states or tests that dependency, and the missing directory has been raised in
review on #2180 and again on #2193, each time needing the driver checked before
it could be answered.
One visible difference on a fresh checkout: the directory now arrives at 0750
rather than the 0755 the driver's own mkdir leaves, both measured. It runs only
on a test that has already failed, and logs its error rather than swallowing
it, matching the Stop call below it.
* Read the collapsed-threads key through getJsonItem
`getFromLocalStorage` parsed the stored string directly, so anything
malformed under `__remarkCollapsed` threw out of `restoreCollapsedThreads`.
That call sits in `remark.tsx` ahead of the `render`, so the throw took the
whole widget with it: the reader was left on the preloader, over a view
preference.
`getJsonItem` in `common/local-storage.ts` already wraps a parse of a
localStorage key and returns null on failure, and null is a shape the check
below already reads as empty. The rest of that function is total against
whatever the browser holds, and the bare parse was the one way in.
* Stop retrying a failed e2e test in CI
The suite went in with one gotestsum rerun. It has no failures on record to
justify that: 31 CI runs since it landed, all green, and no rerun report has
ever been produced. A retry is what turns an intermittent regression into a
green build, and while the suite is this young its own failures are the
evidence worth keeping.
`E2E_RUN_ID` stays. It stamps the threads a run works on with the CI run id, so
a thread url in a trace or a log names the run it came from. It carries no data
across: the stack is disposable, and a local run under the same id gets those
urls on an empty database.
* Stop two chooseUnusedPort comments claiming collisions cannot happen
All four copies listen on :0, read the assigned port, close the listener
and bind later, so nothing holds the number across that gap and another
binary can take it. The copies in app/cmd and app/rest/api call a collision
very unlikely, which is accurate; the ones in app and the example module
said binaries never land on the same number, which is not, and a comment
ruling out a port collision is what would send the next person chasing one
somewhere else. All four now read the same.
Closing the window rather than describing it means the server binding :0
itself and reporting the address it got, which is a larger change.
* Make backend tests wait on conditions instead of durations
The backend workflow has a long tail of runs that fail once and pass on
a rerun. Every one of them comes down to a test assuming an operation
finishes within some duration rather than waiting for the state it
needs. Three were reproducible and each was reproduced against the old
code before being changed: TestServerAuthHooks minted a token that lived
one second and never tested expiry, so a slow runner turned the first
POST into a 401; TestServerApp_AnonMode saw "connection refused" because
waitForHTTPServerStart returned silently after three seconds and left a
later assertion to fail with something unrelated; TestFsStore_Cleanup
slept 200ms against a 300ms ttl that Cleanup widens to 400ms with its
commit grace, so roughly 100ms of stall collected an image meant to
survive.
Fixed sleeps before asserting on asynchronous work are replaced with
polls on the condition itself, using require.Eventually and
require.EventuallyWithT, and require.Never where the assertion is that
something did not happen. Polling closures assert on the CollectT they
are handed rather than on t, since testify runs them on another
goroutine, and polls that issue HTTP requests stay under the rate limit
on the routes they poll through.
Where a test needs time to have passed, the clock input is pinned
instead: staging ages are stamped with os.Chtimes on both sides of the
cleanup boundary right before each call, which also makes the 100ms
commit grace an exact case rather than something no assertion reaches,
and the RSS tests set store.Comment.Timestamp explicitly rather than
racing the wall clock into the first 100ms of a second so pubDate
matches.
chooseUnusedPort takes a port from the kernel's ephemeral range. Picking
at random out of a fixed 10000-port window let two package binaries,
which go test ./... runs concurrently, land on the same number between
the probe closing and the server binding. The start helpers fail naming
the port they waited on, and the SSL tests wait on the redirect port as
well as the TLS one.
Arbitrary budgets that nothing tests are gone: ten HTTP clients with a
one-second timeout against bolt-backed import and export, the "should
take about 100msec" assertions, and a one-second bound on noticing an
already cancelled context. Shutdown stays bounded at ten seconds so a
hang is still caught.
Two assertions get stronger. TestServerAuthHooks accepted 403 or 401
from a blocked user, an alternative that existed only because the short
token could expire mid-test; it is deterministically 403 now.
TestAdmin_BlockedList asserted two users blocked while one carried the
same 150ms ttl the next step waits to lapse, so the halves raced each
other.
goleak stops reporting the regexp2 clock goroutine, which chroma pulls
in for syntax highlighting and which lives for up to a second after the
last match with a timeout; it ends on its own but a binary finishing
inside that window was reported as leaking, and this suite now finishes
sooner. The ignore for net/http.(*Server).Shutdown goes the other way:
it no longer matches anything, with both packages run fifteen times each
under CPU oversubscription to confirm.
Two gaps the change would otherwise have opened are covered directly
rather than left to the side effects that used to cover them. The
one-second token was the only thing exercising the authenticator's
ClaimsUpd hook on refresh, so TestServerApp_ClaimsUpd now calls the hook
itself and checks admin, blocked, email and restricted-name
impersonation, including the two pass-through cases. Lifting the
open-route limit removed the last incidental exercise of the rate
limiter, so TestRateLimiter drives a burst past the allowance and checks
the refusals and that the limit is per client. Both run without a wall
clock, and both were confirmed to fail when the behaviour they cover is
removed.
Production code is untouched. The two sleeps outside test code, the 429
backoff in cmd/cleanup.go and the submit poll in store/image/image.go,
are left alone: no CI failure implicates them.
Test sleeps drop from 67 to 21, all of them either inside a
testing/synctest bubble or a poll interval. The suite runs in about 22
seconds instead of 46, mostly because
TestPublic_FindCommentsCtrl_ConsistentCount no longer paces a hundred
subtests with an 80ms sleep each to stay under the open route limit. The
300s per-package budget now matches across both workflows, the race_test
target and the documented command, and CLAUDE.md records the convention.

* Apply go fix under Go 1.27
Go 1.27 extends go fix with the modernizers, so `go fix ./...` now
rewrites patterns the language has since replaced. Running it across all
three modules produces this: legacy sync/atomic calls on plain integers
become the atomic types (notify.Service.closed, image.Service.term and
submitCount, and several test counters), reverse index loops become
slices.Backward, a Split-then-index becomes strings.Cut, counted loops
become range over an int, and interface{} becomes any in the e2e suite.
The example module needed no changes. The e2e module is behind a build
tag, so it only matches with `go fix -tags e2e ./...`.
One knock-on: prealloc can see the bound of a loop once it is written as
range over an int, so the slice it feeds is now preallocated.

* Fix collapsed threads not restoring, and the clock skew correction
Collapse state was kept as a flat list of `siteID_url_commentID` strings
and read back by splitting on `_`. Any underscore in the url, the site id
or the comment id made the pieces impossible to tell apart, so a page
whose url contains one lost its collapsed threads on every reload, and one
page's entries could be read or deleted as another's: `/post` matched
everything stored for `/post_2`, and a site id of `blog` matched `blog_ru`.
No separator fixes that, since every candidate can occur inside the values,
so the ids are now nested under the site and the url instead. Anything
stored in the old shape reads as empty: collapsed threads are a view
preference, and re-expanding them once is not worth a migration.
The e2e suite had been stripping underscores out of its own thread urls to
work around this, which left its collapse test unable to fail on the bug it
covers. That workaround is gone, and the test now fails without this fix.
`serverClientTimeDiff` was written in seconds and added to an epoch in
milliseconds, so the correction it exists to apply was a thousandth of the
real skew. It is now milliseconds, and named for the unit.
A response with no usable `date` used to fall back to a zero timestamp,
which already made the "skew" about twenty days and would have made it
fifty-five years once the units were right. Nothing is stored now unless
the reading is plausible, since `Date.parse` is lenient enough to turn junk
into a date and let an absurd value through the branch that parses.
The score tooltip reports controversy again when there is any. It has been
dead since the vote component was rewritten in 0e4ae6e0, which moved the
score into its own component and left the line behind commented out; the
value has been passed in and dropped ever since. Unlike the original it
stays out of the way when there is no controversy, which the backend sends
as an absent field rather than a zero.
* Drop the nested frontend dockerignore
Docker reads `.dockerignore` from the build context root only, and nothing
builds from `frontend/`: every context in the repo is the repository root,
apart from the site, which has its own. There is no Dockerfile under
`frontend/` any more either. So the file was never consulted, and both
lines it carried, `/.vscode/` and `/.idea/`, are already in the root
`.dockerignore` verbatim.
The test slept 200ms, ran Cleanup with a 300ms TTL and then asserted the
second and third staged images survived. Cleanup collects anything older than
the TTL plus a 100ms commit grace, and the second image was already 300ms old
by then, so a runner that stalled ~100ms anywhere in the setup aged it past
the line and the assertion failed with "file on staging".
Age comes from the file's modification time, so the test now sets it with
os.Chtimes on both sides of the boundary immediately before each Cleanup call:
the image meant to be collected is backdated an hour, the ones meant to
survive are stamped at now. That leaves no window for a stall to age a file
into the wrong bucket, and drops 600ms of sleeping.
Verified by injecting a stall into the setup: 250ms reproduces the failure on
the current code, while the version here survives 2s.
The three reveal tests timed their budgets from before `page.Goto`, so a
slow navigation was spent against a window that belongs to the iframe. In
`TestIframe_StaysHiddenUntilTheDocumentReportsInited` that made the test
vacuous rather than flaky: on a navigation between 2.5 and 5 seconds the
loop bounding the visibility assertion had no budget left, ran zero times,
and the test passed having asserted nothing. Reproduced by delaying the
demo document by three seconds, where the assertion ran 0 times before and
runs 23 after. The timeout test had the mirror of it, with navigation
counting toward the lower bound that exists to catch a shortened fallback.
An init script now records, in the page, when the widget's iframe element
enters the document and when its visibility first flips. `create-iframe.ts`
arms its fallback a moment earlier, on the detached element, so these read
a shade short and every bound is conservative in the same direction.
Both bounds were also wider than the thing they guard. The hidden window
now runs almost to the fallback rather than half of it, and the lower bound
sits just under it rather than at three quarters, which a fallback
shortened to four seconds used to clear.
CI reruns a failing test once rather than failing the build on the first
flake. A browser suite has a floor no amount of care removes, and one flake
failing the build is what stops people trusting the suite. Once rather than
twice, because a rerun stops at the first pass and each further attempt
only widens the window where a real intermittent regression is absorbed.
What needed a rerun is written to a report and uploaded with the traces,
which are kept whether or not the job went green: a run that recovered on
the rerun is exactly the one whose evidence used to be discarded.
`telegram-link.tsx` assembles that paragraph from five separate messages
with the anchor and the QR clause in the middle, joining them with a
hardcoded space. Japanese and Chinese do not put spaces between words, so
the assembled sentence carried them mid-clause: `通过 此链接 或扫描二维码
打开 Telegram，` separated a preposition from its object and an adverbial
phrase from its verb. The separator now comes from the locale and is
empty for `ja`, `zh` and `zh-tw`. Korean keeps its spaces, because Korean
uses them, as do Thai's phrase boundaries.
The locale is matched exactly as `loadLocale` matches it. Comparing case
insensitively would have been worse than the bug: `remark_config.locale`
is forwarded verbatim and `loadLocale` is case sensitive, so a
conventional `zh-TW` loads the English catalogue, and a lowercased
comparison would then join English words with nothing between them. The
test covers that case alongside `ja` and `en`, and fails if either the
comparison loosens or the separator stops depending on the locale.
Macedonian labelled the replies feed as comments. `subscribeByRSS.replies`
carried `Коментари`, the same value as `user.comments`, in a catalogue
whose two reply strings are both `Одговори`. That option subscribes to
`/rss/reply?user=`, which `UserReplies` documents as comments replied to
that user, so the feed is replies.
`auth.user-not-found` is removed. It reached every catalogue but could not
render: the only dynamic path to it is `messages[invalidReason]`, and
`invalidReason` comes from `getTokenInvalidReason`, which returns
`expiredToken`, `invalidToken` or null, or from a backend error string,
and the backend emits nothing matching. Catalogues go from 181 keys to
180.
Four upgrades that were finished but never merged, the compiler collapse
they enable, and the dependency sweep that follows. Direct
devDependencies go from 78 to 60 and dependencies from 10 to 9.
Three were doing the same job: `ts-loader` stripped types in webpack,
`babel-loader` did everything else, and `@swc/jest` repeated both for the
tests with its own copy of the JSX settings. Babel is the one that
survives, because the `data-testid` stripper has no equivalent elsewhere.
`ts-loader` ran `transpileOnly: true`, so it only stripped types, which
`@babel/preset-typescript` does; `fork-ts-checker-webpack-plugin` was
already what type-checks. Jest runs `babel-jest` against the same
`.babelrc.js` the bundle uses, passed as `configFile` because a
file-relative babel config does not reach the `node_modules` packages in
`transformIgnorePatterns`, and `jest.config.mjs` is plain ESM because a
`.ts` config is compiled against `tsconfig.json`, whose
`verbatimModuleSyntax` rejects ESM syntax in a file the package has not
declared as a module.
That removes `ts-loader`, `@swc/jest` and `@swc/core`. The last was
pinned to 1.2.205 from 2022 with no way forward, because newer builds
emit non-configurable exports and break `jest.spyOn` across 13 suites.
Babel compiles a file at a time with no type information, so it cannot
tell a type-only import from a real one and keeps the module. One line,
`import { boundActions } from './connected-comment'`, pulled the whole
redux store into `last-comments.mjs` and doubled it. `verbatimModuleSyntax`
and `@typescript-eslint/consistent-type-imports` mark them properly; the
statement has to be a separate `import type`, since verbatim semantics
keep an inline `import { type X }` and load the module anyway.
The legacy and modern compilations produced the same bytes. Both read the
same browserslist query, `defaults, not IE 11, not samsung 12` resolves to
chrome 109 and up, and nothing in the source needs transforming for that
set, so 28 of the 29 output pairs were byte-identical.
That made the module/nomodule switch worse than redundant: it served the
`.js` file to browsers with no ES module support, and those files carried
`??`, `?.` and class fields, so the fallback handed its own audience a
syntax error. There is now one bundle, always loaded as a module, in the
five templates and in the seven `site/` documents integrators copy from.
A production build emits 29 files rather than 58, in about 3 seconds
rather than 17. Two of those documents did not work at all beforehand:
the SPA snippet could not parse, and the subdomain example had an
unterminated string.
`@babel/core` 8 declares `^22.18 || >=24.11` and `size-limit` 13 declares
`^22.18 || ^24 || >=26`, so 20 was below the floor of two things installed
here; pnpm only warns, which is why every build passed. All seven places
the frontend pins it move together. `site/` is untouched: it builds with
yarn and eleventy and installs neither.
`eslint --print-config` before and after gives 173 active rules on an
application file against 172, and 172 on a spec file and a plain JS file
against 171. What is gone is three `flowtype` rules with no Flow here,
`no-new-object` and `no-new-symbol` whose upstream replacements are on,
`react/forbid-foreign-prop-types` with no propTypes anywhere, and, on TS
only, `no-useless-constructor`, whose typescript-eslint version is on at
error. `@babel/core` is pinned to 8 across the workspace because
`@jest/transform` and `istanbul-lib-instrument` depend on 7 outright; a
second scoped override holds `eslint-config-preact` on 7, since its
`@babel/eslint-parser` loads babel 7 syntax plugins.
`fast-async` rewrote every async function into nodent promise chains,
calls babel's `transform` synchronously, which babel 8 removed, and every
browser in the target list runs async natively. `prefresh` blew its stack
on `createContext` under babel 8 with no newer release to move to, which
compiled `intl.tsx` and `store/context.tsx` into throwing stubs, so
`pnpm dev:app` could not run the widget at all. `core-js` is not injected
now that `useBuiltIns` is gone, `postcss-custom-properties` was reached
directly although nothing declared it and resolved only through pnpm's
private hoist directory, and `cssnano` ran in both postcss chains although
`CssMinimizerPlugin` already uses it.
`pnpm lint`, `pnpm test` and `pnpm build` now work from `frontend/` as
`CLAUDE.md` and the contributing guide have always said they do; the
workspace root defined none of them.
Dependabot updates `backend/` only, so the example module that replaces
it with `../../` keeps the old versions as indirect entries and the
`test examples` job fails with `go: updates to go.mod needed`.
Beyond testify itself this picks up the yaml module move, from
`gopkg.in/yaml.v3` to `go.yaml.in/yaml/v3`, and drops two indirect
entries nothing needs any more.
* Serve the build-independent web assets from the backend
`privacy.html`, `markdown-help.html` and the `400x400.jpeg` it embeds carry
no template variable, link no script or stylesheet, and are imported by
nothing in the widget. They now live in `backend/app/webassets/assets`,
embedded there, and are served under `/web` alongside the frontend build.
`/web` reads the frontend build first and falls back to them, which is what
lets an operator replace one by dropping a file into `--web-root`. That is
what `privacy.html` needs: it describes remark42.com, while the
authorization guide tells operators to hand its URL to Google and Facebook
as their own application's privacy policy.
Only a missing file falls through. An unreadable file in the web root keeps
reporting as unreadable rather than being silently replaced by the embedded
copy, and a name the filesystem rejects reports as missing rather than as a
server error, both matching what `http.Dir` did.
The dev server serves the same directory, so the Markdown help link in the
comment form resolves on the dev port as well as in production.
The two pages are served as they are written. `markdown-help.html` was
minified before, and its formatted inline stylesheet is most of its 8.5 kB;
that is 2.4 kB more over the wire, behind the hour-long cache header the
file server already sets.
Drops `copy-webpack-plugin`, which had no other pattern, and the stylelint
entries that only ever matched these files.
* Make pnpm dev:app start again
The dev server has been failing to start on two counts, so the flow the
contributing guide documents does not run at all.
`webpack-cli` 4 drives `webpack-dev-server` 5 through the argument order
of an older major, handing it the compiler where it expects the options
object. It rejects that against its schema and exits, complaining about an
unknown `_assetEmittingPreviousFiles` property, which is a field of the
compiler. `webpack-cli` 7 is the release that declares
`webpack-dev-server` 5 as a peer.
Past that, `http-proxy-middleware` resolves to 4.1.1, which no longer
accepts the two-argument call `webpack-dev-server` makes, so the `/api`
and `/auth` proxies throw on startup. It is pulled in by the security
override for CVE-2025-32996, the only override in the file with no upper
bound: `>=2.0.10` matches every later major. Bounding it to the 2.x line
keeps the fix and the API `webpack-dev-server` calls.
With both in place `pnpm dev:app` serves the widget and the pages under
`/web` on port 9000.
* Move the site from eleventy to hugo
The site is built by a single static binary. No node, no package manager,
no lockfile, and the toolchain it needed is gone: eleventy, tailwind,
postcss, markdown-it and its three plugins, date-fns, prism, npm-run-all,
cross-env and html-minifier-terser.
Hugo covers most of that itself. Chroma replaces prism, goldmark replaces
markdown-it, `--minify` replaces html-minifier-terser, and fingerprinted
asset URLs replace the cache-busting `version` shortcode that stamped
`Date.now()` into every stylesheet link.
`assets/styles.css` is hand-written, since tailwind was the only reason
left to keep a package manager. The palette and the light and dark values
are custom properties at the top of the file; the minified stylesheet is
15 kB against tailwind's 46 kB, and the whole build 1.0 MB against 1.2 MB.
It was matched to the old one by comparing computed styles rather than by
eye, which is how the heading weights and line heights, the list marker
colour, and the home page heading and sign-off were caught: the last of
those had been carried by tailwind utilities written into the markup.
The `::: note` container becomes a `note` shortcode taking the emoji to
show. Its closer needs a blank line after it, because a shortcode is not
a block rule the way `markdown-it-container` was, and without one goldmark
keeps the callout inside the open paragraph. The `overflow-x` wrapper
around tables and the heading anchors are goldmark render hooks.
Syntax guessing is off. Chroma detected a systemd unit file as gdscript
and a chat transcript as mysql, and colouring a snippet as the wrong
language is worse than not colouring it. The two chroma themes are scoped
to opposite sides of the theme switch rather than layered, because they do
not declare the same properties on the same tokens: github gives Error a
background github-dark never overrides, and styles Punctuation where
github-dark leaves it alone. Layered, either leaves a light value applying
on a dark page.
`[frontmatter] lastmod` resolves through git, then front matter, then file
modification time. Without that chain `.Lastmod` falls back to `.Date`,
which is zero when a page carries no date, and every page reads
`Jan 01, 0001`. `enableGitInfo` is off because the image build context is
`site/` alone, where hugo fails hard rather than degrading;
`HUGO_ENABLEGITINFO=true` gives real per-page commit dates locally.
Three fixes fall out of the move rather than being sought:
- `/docs/` redirected nowhere. The stub was a markdown file whose
permalink was a template expression while `markdownTemplateEngine` was
false, so it never rendered and the URL 404'd. It is an alias now
- `/docs/contributing/` pointed at `/docs/contributing/development/`,
which has never existed. It points at the backend page
- the 404 page was built to `/404/` and nothing served it. Hugo writes it
to `/404.html` and reproxy is told to use it
The mobile documentation menu is a checkbox and label. `visibility: hidden`
on the checkbox, which is what the old `invisible` utility set, takes it
out of the tab order, and a label is not focusable on its own, so the menu
could not be opened from the keyboard at all. The checkbox is clipped
rather than hidden, and its label shows a focus ring.
Content is unchanged. Every code block on every page is byte-identical to
the eleventy output; the only prose difference is that two example values,
`mysite.com` and a quoted `https://demo.remark42.com`, are no longer
turned into links, goldmark's linkify being narrower than markdown-it's.
`backend/README.md` and `frontend/apps/remark42/README.md` are symlinks
into the docs tree and follow it to `site/content/`, as does the path
`release.yml` watches. `frontend/CLAUDE.md` described the site as a node
and yarn project in four places.
* Keep the heading anchors markdown-it generated
Goldmark strips punctuation markdown-it kept, so 22 headings holding a
dot, slash, apostrophe, question mark, bracket or em dash would take a new
id and any link into one from outside the repository would stop resolving.
Those headings carry their previous id as well, as an empty target emitted
ahead of the heading by the render hook, from a map of content path to old
anchor in `data/anchor_aliases.json`. The map was built by matching
heading text between the two builds rather than by position, so it
survives a heading being added or moved.
The hook rather than markdown, because goldmark's `{#id}` attribute syntax
cannot express these: it accepts dots, apostrophes and em dashes but
treats a slash, a question mark, a bracket or a percent sign as heading
text, which is 11 of the 22. The ids are stored percent-decoded, since a
browser decodes a fragment before matching, so `#children%E2%80%99s-privacy`
finds `children’s-privacy`. Verified by navigating to the awkward ones
against the built image and measuring where the page settles: each lands
112px down, which is the header offset the target carries.
Three pages carried no title, so the docs template rendered an empty `<h1>`
above the heading their markdown already had. They take their titles from
that heading text, so neither the wording nor its anchor changes, and the
template's `<h1>` carries an id. One in-page link pointed at an anchor
goldmark no longer generates.
The heading render hook emits no permalink anchor. The one it replaced was
an empty `<a href>` with `pointer-events: none`, so it could not be
clicked, and its only job was a `::before` spacer that `scroll-margin-top`
on the heading already does. Being an `<a href>` it stayed in the tab
order, so every heading was an unexplained keyboard stop: eight on the
installation page alone. Fragment navigation still lands 112px down, clear
of the fixed header.
* Harden the site image build and its CI
The architecture guard could not fire. `${TARGETARCH:-amd64}` defaulted
before the `unsupported arch` branch was reachable, so a build without
buildkit put an amd64 hugo inside an aarch64 image and ran only because
Docker Desktop emulates it. Reproduced with `--build-arg TARGETARCH=`:
`/etc/apk/arch` reported aarch64 and `hugo version` linux/amd64. An empty
value is an error now. `Dockerfile.dev` had the same defect and no smoke
step to catch it, so it would have failed at `compose up`.
The hugo tarball is verified against the release's own `checksums.txt`,
and the match is asserted present before it is used: piping grep straight
into `sha256sum -c` left the guarantee resting on what the checker does
with empty input. Busybox exits 1 there, so it did fail closed, but
nothing in the line said so. Verified against a checksums file that does
not list the tarball: the build stops before the install.
Hugo exits 0 on an empty content tree and emits a two-page shell, which
would have been copied, pushed and deployed. The build asserts the home
page and a docs page exist.
`site/**` pull requests were never built. The only building job is gated
on `github.ref == 'refs/heads/master'`, so on a pull request every job
skipped and rendered in the checks list the same way a pass does, and the
image was first built on the run that also deploys it. A `validate` job
builds it with `push: false`, needing no secrets so it works on a fork.
`.github/dependabot.yml` watched `/site` for npm packages that are gone.
That entry is a docker one, which tracks the alpine base. It does not
track the hugo pin and cannot: the docker ecosystem reads `FROM`
references, and `ARG HUGO_VERSION` is a bare string in a download URL, so
that one is a manual bump and `site/README.md` says so.
`Dockerfile.dev` carries a `COPY`, so the dev image works without the
compose bind mount, and compose runs as the invoking user rather than
root, which on linux left root-owned `public/` and `resources/` in the
checkout.
Recorded in the backlog: `master` has `required_status_checks` off with an
empty check list, so the new job surfaces a red X and does not block a
merge. That is a settings decision rather than a code fix.
* Move the e2e suite to Go and playwright-go
The seven playwright tests in `frontend/e2e` become twenty in `e2e/`, a
separate Go module driving the same browsers through playwright-go. The
npm project, its lockfile entries, its prettier config and
`Dockerfile.e2e` go with it, leaving `frontend/` a single-member
workspace.
The suite covers posting with markdown, replying and the nesting that
implies, editing inside the deadline and the backend refusing one outside
it, deleting, voting with the optimistic score observed mid-flight and
rolled back on failure, changing the sort, collapse persistence across a
reload, dev, anonymous and email sign-in end to end, the profile iframe,
and the two scripts that render into the host page rather than the
widget's own frame.
The rendering tests run in chromium, firefox and webkit. The rest sign in,
sign-in needs the dev oauth2 provider, and reaching that by name from the
host is chromium-only, so they run there alone.
`compose-e2e-test.yml` runs remark42, a second instance with a short edit
window so that path does not need a five-minute test, and mailpit, which
catches the email verification message the suite reads back. Everything
binds to the loopback interface: the stack holds a known secret and an
admin shared id, and `go test` can start it unattended. The tests run on
the host rather than in a container.
Three settings there exist for the tests rather than for realism.
`REMARK_URL` uses a hostname because the dev oauth2 server binds whatever
host it reads out of it, and a loopback bind inside a container cannot be
published. `UPDATE_LIMIT` is raised because the default of 0.5/sec rejects
any test posting twice in a row. The suite also paces its own `/auth/`
calls, which are capped at 2/sec by a bare literal in `rest.go` rather
than by a setting.
Each test gets its own comment thread from a query string on the demo
page, so nothing has to reset the database between runs.
CI gains a vet and lint job for the module, since the build tag keeps it
out of a plain `go test ./...`, and uploads a browser trace for any test
that fails.
`e2e/README.md` carries the rest: how to run it, what the stack is for,
and the widget behaviour the assertions have to work around.
* Update golangci-lint to 2.13.1 in the backend workflow
The pin sat three minors behind what the linter installs locally, so CI
checked the backend with an older set of rules than anyone running it by
hand. 2.10.1 also fetches its config schema over the network on every
`config verify`, which is a failure mode with no bearing on the code.
Both targets are clean on 2.13.1, `backend/app` and the memory_store
example.
* Fix wrong and missing translations across 17 locales
`errors.8` is `ErrReadOnly` (`backend/app/rest/httperrors.go:29`), but 13
catalogues carried a copy of `errors.7`, which is `ErrUserBlocked`. A
reader who simply hit a read-only thread was told they had been blocked,
in Belarusian, Bulgarian, Brazilian Portuguese, German, Finnish, French,
Japanese, Polish, Russian, Turkish, Ukrainian, Vietnamese and Simplified
Chinese. Each now says the page is read-only, in the terminology that
catalogue already uses for its read-only badge.
Czech had an off-by-one: `errors.19`, restricted words, carried the text
of `errors.18`, file not found, and `errors.18` was left in English. So a
comment caught by the word filter reported a missing file. Both rewritten.
Also corrected, all of the same class:
- `de` `vote.downvote` had a leading space
- `mk` had dropped `{shortcut}` from the bold, italic and link tooltips,
losing the keyboard hints
- `fi` `comment.pin` was "Sitoo", which means "it binds", and `comment.unpin`
followed from it; `errors.forbidden` was misspelled "Kieletty."
- `be` `errors.failed-fetch` ended in a stray "r"
- `zh-tw` `authPanel.read-only` wrote 唯獨 for 唯讀
- `ja` `errors.conflict` used 相衝, which is not Japanese usage
- `it` `auth.symbols-restriction` misspelled "numberi" and used "username"
where `auth.username` now says "Nome utente"
Nine Finnish strings, `it` `auth.username` and `zh-tw` `comment.time` were
left in English; `comment.time` is a format string and now matches the
other CJK locales at `{day} {time}`.
No English source string changes, and every runtime placeholder is
preserved. Reviewed by two independent passes, which between them reworded
five of these and found four of the pre-existing defects above.
* Complete every translation catalogue
No locale carries English text any more, and the Telegram authorisation
paragraph now reads as a sentence in all 23 of them.
That paragraph is assembled in `telegram-link.tsx` from five separate
keys with the link and the QR clause in the middle, so a catalogue that
translates each key in isolation produces word salad in any language
whose verb does not sit where English puts it. Japanese rendered as
"テレグラムを開く リンクで または QR コードをスキャン そこで..." and Korean, Persian,
Traditional Chinese and Czech had the same break. Each of those now
splits the sentence at the point its own grammar wants, and every
catalogue was checked by rendering both the wide and the narrow layout,
since the QR clause only appears above 768px.
Ten catalogues also had `auth.telegram-link`, which is the anchor text
and reads "by the link", left as "Telegram bot" from an older source
wording, so the paragraph named the bot twice and never said what the
link was for. Six of the block's keys had never been translated at all
in the 16 locales that ship it, and `auth.telegram-message-1/2/3` were
English in nine. None of these were visible to a check for "value equals
the English string", because none of them equalled it.
Two of the six untranslated keys are word for word the English of their
`subscribeByEmail` siblings, so each catalogue's own existing wording was
reused rather than a second phrasing invented for the same sentence.
Quotation marks in that paragraph now follow each language rather than
the English source: «» for be, ua, ru, fa, fr and ar, „“ for bg, cs, de
and mk, „” for pl and ro, ”” for fi, 「」 for ja and zh-tw.
The button the paragraph tells the reader to press is Telegram's own, and
Telegram ships no interface translation for Japanese, Thai or Vietnamese,
so those three now name it the way Russian and Traditional Chinese
already did, with the Latin label alongside the translated one.
Also swept and fixed: Vietnamese "Bằng đã huỷ đăng kí" for "Bạn", Spanish
"ó" for "o", Thai "คลิ๊ก" for "คลิก", an unclosed quotation mark in Arabic
`commentForm.upload-file-fail`, German alternating between tippen and
klicken for the same action, Czech infinitive "Otevřít" where the rest of
the paragraph is imperative, Macedonian "СО ЛИНК" in caps, French
"Sélectionner" on a button the text calls "Vérifier", a missing space
after a full stop in `ua` `errors.9`, and double spaces in `mk`, `pl` and
`vi`.
Left identical to English on purpose, because the word is the same in
that language: `RSS` and `Telegram` everywhere, "Email" in be, it, pl,
ro, ua and vi, "Site" in bp, fr and ro, and "Conflict." in ro. German and
Turkish do not use bare "Site" and say "Website" and "Web sitesi".
Second and final step of #2166. `react-intl` is replaced by
`app/common/intl.tsx`, a small i18n binding over Preact context, and with
`react-redux` already gone nothing holds the React compatibility alias.
React is now absent from the lockfile, the installed tree, the config and
the bundles: `react`, `react-dom`, `react-intl`, `@types/react`,
`@preact/compat`, `use-sync-external-store` and `intl-messageformat` are
all gone, along with the `paths` entries in `tsconfig.json` and three
babel-loader excludes. Runtime dependencies go from 15 to 10.
`preact/compat` goes too, which matters more than its 3.8 kB. Importing
it anywhere installs hooks on preact's shared `options` that remap
`onFocus`/`onBlur` to `focusin`/`focusout` for every element and make
`@testing-library/preact` rewrite `change` to `input`, the two bugs
behind #2166, still live until now. `Button` was wrapped in `forwardRef`
with no caller passing one, and `TextareaAutosize` now takes its ref as
an ordinary prop. The workaround in `sort-picker.spec.tsx` is gone with
them, since `fireEvent.change` reaches a `<select>` again.
Gzipped, against master: `remark.mjs` 76.17 kB to 56.47, `last-comments.mjs`
37.97 to 18.26, `deleteme.mjs` 14.51 to 8.42. The limits move with them and
keep more relative headroom than master shipped.
### The binding
`IntlProvider`, `useIntl`, `createIntl`, `defineMessages`,
`FormattedMessage` and `IntlShape`. 32 files change only their import.
The export names copy react-intl's deliberately: `formatjs extract` finds
messages by recognising `defineMessages`, `FormattedMessage` and
`intl.formatMessage` in the AST rather than by import source, so renaming
one silently empties the catalogue. `frontend/CLAUDE.md` records that,
along with the destructive part: `translation:generate` would then strip
the unextracted keys from all 24 catalogues and the check would pass.
A message the binding cannot parse falls back to the message in the
source: a broken, unhandled or nested tag, a brace that is not a
well-formed placeholder, and a placeholder naming a value the caller did
not supply. `mk.json` and `th.json` carried broken markup and rendered in
English; both are repaired, so a catalogue sweep over every locale can now
require well-formed markup with no exceptions listed.
`translation:check` gained the validation that would have caught them when
they were proposed: a translation's tags have to be well-formed pairs of the
names the English string uses, with no attributes, and its placeholders have
to be ones the English string provides. Leaving a tag or a placeholder out
stays allowed. Run against master's catalogues it reports both.
### enzyme
`@types/enzyme` was the last thing pulling `@types/react`, so React could
not leave while enzyme stayed. Its three test files move to
`@testing-library/preact`, which now has no rival: `@testing-library/preact-hooks`
had one import left and its own unmet peer warning. `intersection-observer`
was a runtime dependency nothing imported, and the `cheerio` override lost
its last dependent with enzyme.
Enzyme's `.find(X).prop()` threw unless exactly one node matched, so the
converted tests assert node counts explicitly to keep that.
### Verified
All 181 message ids formatted across all 24 catalogues through both real
react-intl and this binding: 4344 comparisons, no differences. From a wiped
`node_modules`: `pnpm install --frozen-lockfile`, `pnpm lint`,
`pnpm type-check`, `pnpm test` (392 tests, 42 suites), `pnpm build`,
`pnpm size-check`, `pnpm translation-check`.
* Replace react-redux with a preact context binding
One of the two packages holding the @preact/compat alias in place, and
the contained one: the store is plain redux, and the only react-redux
import inside it was a single line re-exporting typed hooks.
* Drop the now-unused react-redux types
* Subscribe before paint and check once on subscribe
Previously, useSelector subscribed to the store inside useEffect, which
runs after paint. A dispatch landing between render and that effect was
never delivered, since the listener did not exist yet, so the component
kept rendering a stale value until some later unrelated dispatch happened
to differ from the stale ref.
Subscribing in useLayoutEffect narrows the window to before paint, and
running the check once immediately on subscribe closes it, which is what
react-redux does for the same reason.
Adds the first tests for the binding, one of which fails without this
change: the store holds 1 while the DOM still shows 0.
* Only re-check on subscribe when the state actually moved
The subscribe-time check ran unconditionally, so it re-ran the selector
at mount. A selector building a fresh object fails Object.is against the
value the render already computed, which forced a second render of every
connected component: ConnectedRoot and every ConnectedComment, so around
201 extra renders for a 200-comment thread.
Reducers return a new root object on every change, so an unchanged state
reference means no dispatch was missed and the check has nothing to find.
Comparing against the state the render used keeps the property the check
exists for while dropping the extra render.
The race test still exercises the guarded path, since its dispatch
produces a new state object, and a new test pins the mount case: it fails
without the guard.
Raised by umputun in review.
* Require node 20 and record every place the version is pinned
The declared floor was >=18 while CI, Docker and both .nvmrc files had
been on 20 since the pnpm 8 to 10 migration, and transitive dependencies
now require 20.18.1. The docs had drifted further still, telling
contributors to install Node 16 and PNPM 8.
* Set the node floor to the strictest dependency and keep one checklist
undici needs >=20.18.1, so a bare >=20 advertised support for 20.0 to
20.18.0, which fail dependency engine checks. frontend/CLAUDE.md already
carried a pinning checklist, so the new entries fold into it rather than
starting a rival list in the root file.
* Keep the node floor at the major, not a patch version
engines.node states the major we support. Individual dev dependencies
can be stricter within it, and chasing those patch floors into engines
and the docs would turn every lockfile refresh into a docs change.
* Update preact to 10.29.8
Also moves TypeScript to 5.9, which preact 10.29 typings require, and the
compat and testing library pins that go with it. Type checking resolves
JSX from preact via the automatic runtime; the bundle keeps the classic
transform so babel still strips test ids.
* Move babel to the automatic JSX runtime and refresh frontend notes
Leaving babel on the classic h pragma while tsconfig used the automatic
runtime meant a tsx file without an h import would type-check and lint
clean, then throw at runtime, since eslint-config-preact disables
react/react-in-jsx-scope and no-undef is off.
* Address review findings on the preact upgrade
Forward the textarea ref with useImperativeHandle so it clears on unmount
and lands during commit rather than after paint. Pair typescript-eslint
with the TypeScript it now has to parse. Use the preact namespace types
rather than the deprecated JSX aliases, and drop the redundant type
re-declarations the element-specific interfaces already provide.
* Drive the focus tests through real DOM focus and blur
Dispatching a synthetic focusin hard-coded preact/compat's internal
alias for onFocus. Calling focus() and blur() exercises the sequence a
browser produces and stays correct if that mapping changes.
* Raise the two bundle limits the preact upgrade pushes past
CI measures remark.mjs at 78024 bytes against a limit size-limit reads as
78000, so it failed by 24. last-comments.mjs had 36 bytes of headroom and
would have tripped on the next change.
* Regenerate the lockfile after the rebase
The rebase resolution left it missing the @typescript-eslint entries, so
every CI job failed at pnpm install --frozen-lockfile.
frontend/* required @akellbl4 or @Mavrin, so umputun could not satisfy the
code-owner rule on any frontend pull request. #2172 needed an admin override
and #2163 could not use one, because GitHub routes stacked pull requests
through the async merge endpoint, which applies no override.
The path filter matched only frontend/apps/remark42/**, so a change to the
workspace root ran nothing: no lint, type-check, tests or size-limit, and no
docker build either since docker.yml waits on this workflow by name.
#2160 rewrote pnpm-lock.yaml and the override block, and #2172 removed a
workspace package and its CI workflow. Neither ran a single frontend check on
its PR or on master.
* Drop the @remark42/api package
It cannot authenticate anyone: clients/auth.ts exposes only anonymous,
email and telegram, with no OAuth method, and the fetcher never sets
credentials so its cookie auth cannot work cross-origin. Nothing in the
repo consumes it, no third-party consumer exists, and npm has served an
alpha from July 2022 that CI never publishes.
* Drop the removed workflow from the pnpm pinning checklist
frontend/CLAUDE.md still counted ci-frontend-api.yml among the places the
pnpm version is pinned, and stated a fixed total that no longer holds.
All 23 open Dependabot alerts against frontend/pnpm-lock.yaml resolve to
packages whose override floor sat below the patched release. Every floor
now carries an explicit upper bound, as an open-ended floor lets pnpm
resolve across a major version.
* feat: add configurable SMTP HELO hostname
Allow the SMTP HELO/EHLO hostname to be configured separately from
the SMTP server hostname.
This is useful when the SMTP server requires clients to identify
themselves with a fully qualified hostname different from the server
address.
* chore: remove vendored dependency changes
* Bump go-pkgz/notify to v1.4.0 and document SMTP_HELO_HOST
The HELOHost field lands in go-pkgz/notify v1.4.0, so the branch needs the
bump to compile; v1.3.0 in master has no such field. The example module is
tidied alongside, as any change to backend/go.mod requires.
Documents the parameter in the parameters table and, separately, in the email
setup page: what it does, that leaving it unset keeps the previous `localhost`
greeting, and the case it exists for, a relay refusing the greeting under
Postfix `reject_non_fqdn_helo_hostname`.
Also records the current limit: verification emails for email authentication
go through go-pkgz/auth's own sender, which has no equivalent setting, so the
greeting there is unchanged.
* Bump go-pkgz/auth to v2.2.0 and apply SMTP_HELO_HOST to verification email
The verification email sender had no way to set the greeting, so a relay that
refuses the HELO would accept notifications and still reject sign-in emails.
EmailParams gains HELOHost in go-pkgz/auth v2.2.0, so the same SMTP_HELO_HOST
now drives both paths.
The example module is tidied alongside, as any change to backend/go.mod
requires.

rest.CORS refuses "*" together with credentials since go-pkgz/rest#52, so the
bump and the option have to land together: the option does not exist in v1.22.0
and the panic fires at construction, inside routes(), which makes it a startup
failure rather than a request-time one.
The wildcard stays. The comment widget is embedded on arbitrary third-party
sites, so the set of origins is not knowable, which is why the escape hatch was
asked for upstream instead of accepting the panic. What it costs is unchanged
and now written next to the call: any site a signed-in user visits can read
authenticated responses, so state-changing requests have to keep being protected
by something other than the origin, X-XSRF-Token today.
The example module is tidied in the same commit, as it reaches go-pkgz/rest
through the replace directive and its indirect graph would otherwise keep the
old pin and fail the readonly module check in CI.
The bump also carries testify to v1.12.0, which drops go-spew and go-difflib
from the module graph.
govulncheck fails on master against the 1.25.12 pin with seven stdlib
advisories, all fixed in 1.25.13: GO-2026-5026, GO-2026-5972, GO-2026-6088,
GO-2026-6089, GO-2026-6090, GO-2026-6091 and GO-2026-6218, across crypto/tls,
encoding/asn1, encoding/xml, html/template, net/http and net/url.
Pinning the next patch would only move the problem to the following advisory,
as it did in 76d0cc2c. setup-go accepts a minor-only spec, so "1.25" resolves
to a patch on that line at run time. Staying on 1.25 rather than "stable"
keeps a move to a new minor a deliberate change, matching the `go 1.25.0`
directive in both go.mod files.
check-latest is required with it: by default setup-go uses the patch already
cached on the runner image, so a minor-only spec alone would keep resolving
to whatever that image ships, currently 1.25.12, and the scan would stay red.
Previously the rule was scoped to "updating Go modules", which reads as
version bumps only. Adding or removing a dependency, or changing the `go`
directive, puts the example module out of step in exactly the same way, and
the failure is the same `test examples` step reporting "updates to go.mod
needed".
Also records that Dependabot Go module PRs need this, since the bot updates
`backend/` alone.
Excessive memory allocation during VP8L decoding, reachable from
app/store/image/image.go:333 where image.Decode runs on uploaded data.
The existing DecodeConfig dimension guard doesn't cover it, since the
over-allocation happens during decode rather than from declared dimensions.
Tidies backend/_example/memory_store in the same commit: it carries the
backend's deps as indirect entries and would otherwise fail the example CI step.
Previously the widget document had `padding: 6px` on the body, so every
embedded widget sat 6px inside its container and could not align flush with
the host layout. `updateIframeHeight` then reported
`document.body.offsetHeight + 12`, but the body is `box-sizing: border-box`
and `offsetHeight` already includes padding, so the addition double-counted
it.
Measured against the deployed widget: the content needs 20610px, the body
reported 20622px with the padding, and the parent was told 20634px, leaving
24px of empty space below every embed on top of the horizontal inset.
Removing the padding does not clip anything. With it at zero, offsetHeight,
body scrollHeight and documentElement scrollHeight all agree, and the last
child carries no bottom margin, so no margin collapses through the body edge.
Resolves#1487.
Previously the pages Remark42 serves from /web/ carried a build-time host.
The `{% REMARK_URL %}` placeholder is substituted during the image and
release-asset builds, both of which write `http://127.0.0.1:8080`. Docker
rewrites it again at container start from REMARK_URL, but a release binary
has no equivalent step, so it serves demo, counter, last-comments and
deleteme pages pointing at the visitor's own loopback address. `counter.ejs`
additionally had that address hardcoded in two "note" links, which no
substitution touched.
These pages are served by Remark42 itself, so the host is whatever origin and
path prefix delivered them. Deriving it from `location` is correct at the root
and under a path prefix alike, and needs no build-time value. Sibling links
are now relative for the same reason.
`site_id` is left as a literal so the startup substitution in docker-init.sh
keeps matching it.
Reported by @andreas-hempel.
Resolves#1996.
Previously any message reaching the widget closed the Sign In dropdown,
because the handler returned early only for a clickOutside payload while
closing was disabled and fell through to closing in every other case. The
embedding page posts hash, title and theme messages of its own, and
`embed.ts` installs a MutationObserver on the host page title that posts on
every mutation, so a host page whose title changes closes an open login form
and discards whatever was typed into it. Browser extensions that post into
the page have the same effect.
After this change the dropdown closes only for a clickOutside payload from
`window.parent`. Reproduced against the deployed demo: with the form open and
filled, a single `document.title` assignment on the host page removed it,
while three seconds of inactivity did not.
Resolves#2139.
Previously the npm entries carried only open-pull-requests-limit: 0, which
bounds version updates and leaves security updates unlimited, so npm pull
requests kept arriving from Dependabot alerts. The ignore option applies to
both kinds, so a blanket ignore per npm entry is what actually stops them.
Go modules and GitHub Actions updates are unchanged.
Previously the Microsoft setup instructions did not mention supported
account types. Remark42 authenticates against the `common` endpoint by
default, which only accepts an application registered for both work or
school accounts and personal Microsoft accounts, so an application created
with any other value fails to authenticate with no hint as to why.
The reproxy manual still configured `AUTH_TWITTER_CID` and
`AUTH_TWITTER_CSEC` in its example, which have been deprecated and
non-functional since 1.14.0.
Resolves#1823.
site/** pull requests get no build validation: ci-site.yml declares a
pull_request trigger but gates its only build job to master and tags, so
a bad site lockfile first fails on the post-merge run that deploys.
frontend pnpm override floors still admit js-yaml 3.15.0 and 5.2.0,
leaving three open advisories including the one PR 2141 closed for site/.
alterComment issued two engine.Flag calls (Blocked, then Verified) for
every comment, so a listing of N comments triggered up to 2N BoltDB read
transactions even when many comments shared the same author. Find,
FindSince, User and Last all funnel through it.
Add a userFlagCache that memoises blocked/verified results by site and
user for the duration of a single listing, so repeated authors are
looked up once. alterComment keeps its signature for single-comment
callers (Get) by using a fresh cache; the batch paths share one.
#2122 collapsed the per-registry builds into one build with two type=image
outputs and a single steps.build.outputs.digest. With build-push-action's
default provenance attestation, that digest does not resolve at ghcr, so the
multi-arch manifest step fails ("ghcr.io/...@sha256:...: not found"). Restore
the separate build-ghcr / build-dockerhub steps so each registry gets its own
digest. The ci-build.yml type=gha cache change from #2122 is kept.
exportCtrl mapped every export failure to 500 Internal Server Error, so
requesting a backup for a non-existent site (e.g. wrong -s/--site) came
back as a misleading 500 instead of a client error — inconsistent with
the rest of the admin/public API, which returns 400 + ErrSiteNotFound
for site-lookup failures.
Add an engine.ErrSiteNotFound sentinel (wrapped at the bolt db-lookup so
the existing "site %q not found" message is unchanged) and map it to 400
+ rest.ErrSiteNotFound in exportCtrl; genuine internal failures (gzip
close/write) still return 500.
Milestones: one vX.Y.Z per release; decide a PR's release by whether its merge
commit is contained in a release tag (git tag --contains), not by dates; issues
get a milestone only when closed by a code change. Plus the issue-label taxonomy
(type / area / priority / contribution / resolution).
setup-go with go-version "1.25" resolved to 1.25.11, which govulncheck flags for
GO-2026-5856 (ECH privacy leak in crypto/tls, fixed in go1.25.12). Pin the exact
patch in ci-backend.yml and release.yml so the vuln scan passes and release
binaries build on the fixed toolchain.
ci-build.yml used the legacy actions/cache + /tmp/.buildx-cache local
cache with a manual rotate step. Switch it to buildx type=gha cache
(separate scopes for the main and example images), dropping the
actions/cache and rotate-cache steps.
docker.yml built each image twice per platform — one build-push-action
call per registry. Build once and push the same content-addressed image
to both ghcr.io and DockerHub via multiple outputs; the single build
digest is identical for both registries, so digest export is simplified
accordingly. The multi-arch manifest merge is unchanged.
The published multi-arch Docker manifest is amd64+arm64 only, but
GoReleaser and the Makefile dockerx target still built linux/arm/v7
binaries with no matching image. Drop the armv7 target (goarch arm +
goarm 7) from .goreleaser.yml and linux/arm/v7 from the Makefile so
shipped binaries match the images; other platforms are unchanged.
Also remove the goconst and lll settings blocks from
backend/.golangci.yml — neither linter is in the enable list, so the
settings were inert.
TestService_WithDrops and TestService_SubmitVerificationWithDrops
submitted three items into a size-1 queue and asserted at least one was
dropped, relying on the single consumer not draining the queue between
submits. synctest does not fully pin this because the MockDest send path
does real logging I/O outside the bubble, so under CI's -race scheduling
the consumer occasionally drained all three, delivering everything and
failing the "<= 2" assertion (~0.2% of CI runs).
Add an optional gate channel to MockDest so a destination blocks in
Send/SendVerification until released. The tests now submit one item (the
consumer picks it up and blocks on the gate), fill the size-1 queue,
submit an overflow item that is dropped, then release the gate — the
drop is deterministic regardless of scheduling. Assert exactly two
delivered instead of "at most two".
Compose files were not covered by any CI workflow, so a malformed change
to docker-compose.yml or a compose-*.yml could merge unnoticed. Add a
workflow that runs docker compose config on every tracked compose file
(vendored ones excluded) on changes to any of them.
Nothing in CI guarded against known vulnerabilities in the Go
dependency tree. Add a vulncheck job that runs govulncheck over the
backend module on every backend change. The version is pinned rather
than tracking latest for reproducible runs. Current tree scans clean.
The test decided the expected HTTP status with strings.Contains(tc.params,
"=bad"), but comment IDs are random UUIDs. When one started with "bad"
(e.g. offset_id=bad49e60-...), the param string contained "=bad" and the
case was wrongly expected to return 400 while the handler correctly
returned 200, failing the run about 0.2% of the time.
Identify bad-request cases by their error response body instead, which
is deterministic per case and independent of the generated IDs.
The limit() boundary used >=, so a subtree that fit the page exactly was
treated as overflow and dropped — under-filling the final page (e.g.
limit=5 over subtrees 3,2 returned only the first subtree, 3 comments,
instead of both). Change it to > so an exact-fit subtree is included;
the first node is still always returned in full and larger subtrees
still overflow to the next page.
Adds table tests for MakeTree's limit/offset pagination and countReplies,
and updates the /find consistent-count expectations for the corrected
boundary.
The top-level version: "2" field is ignored by modern Docker Compose,
which warns about it on every invocation. Drop it from docker-compose.yml
and the compose-dev-backend, compose-dev-frontend and compose-e2e-test
files.
ci-backend.yml had pull_request: types: [opened, reopened], which
excludes synchronize, so pushes to an open PR branch did not re-run
backend tests, lint or coverage and a broken follow-up commit could land
after the first green run. Drop the types filter so all default
pull_request events trigger the workflow.
ci-frontend.yml and ci-frontend-api.yml now install with
pnpm install --frozen-lockfile instead of pnpm i, matching release.yml
and preventing silent lockfile drift in CI.
notify/email.go accumulated multi-recipient errors with
multierror.Append(fmt.Errorf(...)) instead of
multierror.Append(result, ...), so the accumulator was overwritten each
iteration and only the last failing recipient's error survived; earlier
failures were silently dropped. The telegram notifier did it correctly.
Replace hashicorp/go-multierror with the stdlib errors.Join everywhere
it was used (notify/email.go, notify/telegram.go, rest/api/rest_private.go,
store/service/service.go, store/image/image.go and store/engine/bolt.go),
which fixes the bug and drops the direct dependency. It stays indirect
because go-pkgz/lcw/v2 still imports it. A regression test in
email_test.go now sends two failing recipients and asserts both errors
are reported.
on dark host pages the widget flashed an opaque white rectangle while loading.
the iframe element carries color-scheme from the theme param, but its document
had none until remark.tsx ran, and a mismatched color-scheme makes the embedded
canvas opaque instead of transparent. broken since #2023 added the element-side
color-scheme to fix a firefox dark-mode bug.
set the document's color-scheme from the theme param in an inline head script,
before first paint, using the same rule as create-iframe.ts. that closes the long
window but not the surface browsers paint before the document is parsed, which
webkit renders white and chromium hides behind paint holding. so also create the
iframe hidden and reveal it when the document posts inited, with a timeout
fallback so a failed bootstrap cannot leave the widget invisible.
the reveal lives in createIframe rather than embed.ts so the profile modal, the
other caller, gets it too. that modal focuses its iframe on open, and a hidden
element cannot take focus, so focus now fires from the reveal instead of a timer.
covered by a unit test for the reveal paths and the event.source guard, and by
e2e for the document's color-scheme and the iframe's visibility before inited,
after inited, and after the fallback.
the docker workflow chained off the backend workflow only, and backend has a
backend/** path filter. master pushes touching just frontend/apps or the docker
files never triggered docker.yml, so no master image was published and
remark42.com was not redeployed. broken since the build workflow was split in
#1977.
listen to workflow_run from both backend and frontend, and add Dockerfile,
docker-init.sh and .dockerignore to the backend workflow paths to restore the
path coverage the old build workflow had.
On mount ConnectedRoot immediately reported the iframe height to the
parent page while the app was still showing the global preloader, so the
parent shrank the iframe from its initial size to ~63px and then grew it
back step by step as content rendered. On pages with many comments this
reads as the widget blinking several times before loading (reported for
radio-t.com). The June frontend dependency refresh (#2091) shifted
render/effect timing enough to make the premature measurement happen on
every load rather than only on slow connections.
Move the height reporting into Root and start it in the setState callback
that replaces the preloader with real content: the first height message
now always describes rendered content, the iframe never shrinks below it,
and subsequent ResizeObserver updates only grow the frame as comments
arrive. Also adds the previously missing observer disconnect on unmount.
Verified by instrumenting the embed with a height-message listener:
master sent 63px then 316px on an empty test page (v1.16.1 sent a single
316px); with this fix the first message is 316px again.
Follow-up to the review notes on #2116:
- warn at startup when --trusted-proxy contains a catch-all (0.0.0.0/0 or ::/0),
which trusts every peer and re-opens the bypass - mirrors the unset-case warning
- realIPMiddleware tests: cover the unparseable-peer and trusted-peer-without-header
branches, and make the observed values per-call so subtests don't share closure locals
- trim the flag description and shorten the startup warning to the terse [WARN] style
Rate limiting and (with --votes-ip) vote de-duplication key on the client IP,
recovered from forwarding headers (X-Real-IP / X-Forwarded-For / CF-Connecting-IP)
when behind a reverse proxy. Those headers were accepted from any client, so a
caller could set them to change its apparent IP.
Add --trusted-proxy / TRUSTED_PROXY (comma-separated CIDR/IP): forwarding headers
are honored only when the direct peer is a trusted proxy; other peers keep their
real socket address. Unset preserves the previous trust-all behavior (with a
startup warning) so existing deployments keep working on upgrade.
Docs: a 'Trusted proxies and client IP' section with per-topology guidance, plus a
note in the nginx manual.
Bumps go-pkgz/auth to v2.1.5, which adds avatar.ErrNotFound. deleteMeRequestCtrl's
avatar removal was best-effort (log and continue on any error) because before the
sentinel there was no portable way to tell an already-removed avatar from a genuine
failure. It now tolerates only errors.Is(err, avatar.ErrNotFound) - keeping the
repeated-request idempotency - and surfaces any other store failure as 500.
The delete_me token built by deleteMeCtrl omitted the user's Picture, so the
avatar-removal branch in deleteMeRequestCtrl never ran for real requests and
avatars survived account deletion. Carry Picture in the token so the stored
avatar is removed when the request is processed.
Make the removal best-effort: the avatar stores report an already-missing
avatar as an error with no distinguishable sentinel, and the user's data is
already deleted at that point, so a missing avatar (e.g. a repeated request)
no longer fails the whole deletion with a 400.
Only remove a well-formed avatar id ("<hash>.image") so a malformed picture
can't make a filesystem-backed store target an unexpected path.
go-pkgz/rest v1.22.0 ships an enforcing Timeout middleware (net/http.TimeoutHandler
style): it runs the handler with a deadline and returns 504 at the deadline even if
the handler ignores the context - unlike the local cooperative timeout, which only
cancelled the context and never actually stopped a stuck handler.
Replace the local timeout with rest.Timeout on every route with a bounded response.
The streaming and long-polling routes are deliberately left without it, since the
enforcing timeout buffers the whole response in memory and aborts at the deadline:
- GET /api/v1/userdata and GET /api/v1/admin/export stream gzipped exports
- GET /api/v1/admin/wait long-polls for up to 15m
- POST /api/v1/admin/import[/form] and /remap ingest large uploads
Delete the local timeout middleware and its test; the enforcing behaviour is covered
by go-pkgz/rest. TestRouteTimeout locks the enforcing-vs-exempt contract in this build.
v1.22.0 includes the preflight Vary fix (https://github.com/go-pkgz/rest/pull/44):
rest.CORS now adds Vary: Access-Control-Request-Method and
Access-Control-Request-Headers on preflight itself, making the local wrapper
that added them redundant. corsMiddleware now returns rest.CORS directly;
TestCorsMiddleware still asserts those preflight Vary headers, now supplied
upstream.
Also tidies the _example/memory_store module for the new version.
deleteUser now succeeds for a user who has no comments (e.g. one who only logged
in) instead of failing on the missing per-user bucket. In hard mode the per-user
bucket is deleted, tolerating bbolt's ErrBucketNotFound so a bucket left behind by
an earlier partial removal is still removed; the comment-deletion failure path now
wraps the actual error.
Because the engine cannot distinguish a valid login-only user from a never-existed
one, deletion is idempotent: /admin/deleteme returns 200 for an unknown (but validly
signed) token rather than 400. The deleteme test is updated to this contract, engine
tests cover hard and soft deletion of login-only and unknown users, and the API docs
note the idempotent behaviour.
Migrate the REST router off go-chi/chi onto go-pkgz/routegroup (backed by the
stdlib http.ServeMux), removing the last use of go-chi from the backend:
- rest.go routes() builds the tree with routegroup (Mount/Group/Route/With) and
net/http method+path patterns instead of chi's Get/Post/Route/Mount helpers
- chi.URLParam(...) -> r.PathValue(...) in the admin, public and private handlers
- rest_public_test.go loadPictureCtrl test uses routegroup + http.ServeMux
- rest_test.go: add TestRest_FileServerStaticAssets (bare /web -> /web/ redirect,
cache headers, 404, directory-listing block) and update the path-traversal test
for ServeMux normalising a literal ".." (encoded traversal is still rejected
by the handler)
- drop go-chi/chi from go.mod, go.sum and vendor; update the CLAUDE.md reference
Reword "May be" to "Maybe" in the auth.no-providers message and run
translation:generate to register the key in every locale dictionary, then
replace the English placeholders with proper translations for each locale.
Add a test asserting the error is hidden when providers are configured.
Swap the go-chi/cors middleware for rest.CORS (already a dependency),
removing the go-chi/cors module entirely. Behaviour-preserving:
- with AllowedOrigins "*" and credentials enabled, both reflect the request
Origin into Access-Control-Allow-Origin (a literal "*" is invalid with
credentials)
- preflight responses also vary on Access-Control-Request-Method/-Headers, not
just Origin, matching go-chi/cors so caches don't reuse a preflight response
across different requests
Extract the config into corsMiddleware() in middleware.go and add
TestCorsMiddleware covering origin reflection, credentials, preflight
methods/headers/max-age/Vary, and the no-Origin case. go-chi/cors dropped
from go.mod; the chi router stays until the router migration. go test -race,
vet, golangci-lint, govulncheck clean.
The cleanup command test builds a self-contained mock HTTP server with
only static routes (and {id} patterns read via r.URL.Path, not URLParam),
so chi.NewRouter is unnecessary — http.NewServeMux (Go 1.22 routing) covers
it. Independent of the main router; drops the chi import from app/cmd.
go test -race and golangci-lint clean.
Pure relocation, no behaviour change: gather all request-scoped middlewares
and their tests into dedicated files instead of scattering them across
rest.go and ssl.go.
funcs -> app/rest/api/middleware.go:
timeout (from ssl.go); rejectAnonUser, matchSiteID, cacheControl,
apiCSPMiddleware, securityHeadersMiddleware, subscribersOnly,
validEmailAuth, rateLimiter (from rest.go)
tests -> app/rest/api/middleware_test.go:
TestTimeout (from ssl_test.go); TestRest_rejectAnonUser,
TestRest_cacheControl, TestRest_apiCSP, TestRest_securityHeaders,
TestRest_subscribersOnly, Test_validEmailAuth, TestRest_matchSiteID
(from rest_test.go)
go test -race, vet, golangci-lint and govulncheck clean; example builds.
middleware.Timeout was the last use of go-chi/chi/v5/middleware (RealIP, the
other user, landed in #2099). Swap it for the local timeout helper (context
deadline + 504 on deadline, matching chi exactly; covered by TestTimeout),
which removes the go-chi/chi/v5/middleware package from the vendor tree.
The go-chi/chi module stays in go.mod — the router (chi.NewRouter etc.) still
uses it, so go.mod only shrinks after the router migration. Build, vet, race
tests and golangci-lint clean.
Behaviour-preserving swap: rest.RealIP sets r.RemoteAddr from
X-Real-IP / X-Forwarded-For like chi's middleware.RealIP, removing chi from
the RealIP path without changing the trust model (GHSA-56x6-q882-mf27 stays
present, to be fixed separately). chi/middleware stays imported for Timeout;
whichever of this PR and the Timeout PR (#2097) merges last drops the import.
Drop-in to a tested rest middleware; covered by existing api router tests.
go-pkgz/rest.NoCache is borrowed from chi's middleware.NoCache and behaves
identically: same no-cache response headers and the same stripping of
conditional request headers (If-None-Match etc.), which the image-proxy
etag logic relies on. Drop-in swap, chi router left in place.
chi/middleware stays imported for RealIP and Timeout. Build, vet, race
tests and golangci-lint clean.
Drop-in swap of the global concurrency limiter (go-pkgz/rest.Throttle has
the same signature and semantics as chi's middleware.Throttle), with the
chi router left in place. First of the per-middleware swaps that chip away
at go-chi/chi/v5/middleware before the router itself is migrated.
chi/middleware is still imported for RealIP/Timeout/NoCache; build, vet,
race tests and golangci-lint clean.
First step of the go-chi -> go-pkgz/routegroup migration. The HTTP->HTTPS
redirect and ACME http-01 challenge routers are small, self-contained
http.Handlers separate from the main API router, so they move cleanly:
- chi.NewRouter() -> routegroup.New(http.NewServeMux())
- middleware.Throttle -> rest.Throttle (same concurrency-limit semantics)
- middleware.Timeout -> local timeout helper (context deadline, mirrors chi)
- drop middleware.RealIP: these routers do redirect/challenge only, with no
per-IP logic, so the spoofable header trust is simply removed here
- return http.Handler instead of chi.Router (callers already take http.Handler)
chi stays a dependency (still used by the main API router); this only removes
its use from ssl.go. go test -race, vet, golangci-lint and govulncheck clean.
Email notification templates rendered the comment HTML via text/template,
so the store-level UGC sanitizer's permitted <a> and <img> tags reached
the email body verbatim. An authenticated user could plant phishing links
and remote tracking pixels in notification emails sent from the legitimate
remark42 address.
Switch notify to html/template (auto-escaping every non-HTML field) and
add a stricter email-only bluemonday policy that drops <a> and <img> while
keeping basic text formatting; the sanitized comment HTML is passed as
template.HTML. Add regression tests asserting links and images are stripped
while anchor text and formatting survive.
Eleventy passes a falsy outputPath to transforms for templates rendered
without a written file (e.g. permalink: false); calling .endsWith on it
would throw. Skip minification in that case instead. Pre-existing latent
issue surfaced by Copilot review on #2091.
Captures what isn't obvious from the diff alone: the ten places a
node/pnpm version is pinned and must move together (including .nvmrc,
which CI never reads and is how the node-16 drift in this PR's first
push went unnoticed), the pnpm-10 layout pins, the msw 1->2 migration,
the deliberately held-back majors, and the abandoned html-minifier
replacement. Written so the next dependency bump doesn't repeat the
same gaps.
- frontend/.nvmrc was still pinned to 16, left behind by the node 16->20
bump everywhere else (Dockerfile, CI matrices). A contributor running
'nvm use' in frontend/ would land on node 16, which cannot even run
pnpm 10 (requires node >=18) -- CI never reads .nvmrc, so this was
invisible to every check.
- pnpm/action-setup 'version: 10' floated the patch release in CI,
inconsistent with the exact 10.10.0 pin now used in Dockerfile,
Dockerfile.e2e and packageManager. Pinned all ten occurrences across
ci-frontend.yml, ci-frontend-api.yml and release.yml to 10.10.0.
- Pin pnpm to the exact version (10.10.0) when installing it in the
production Dockerfile, matching packageManager and Dockerfile.e2e,
instead of a floating major that can drift the lockfile behaviour.
- Fix mockEndpoint's array header handling in the api test utility:
append each value instead of joining with a comma, which is how
multi-value headers (e.g. set-cookie) are actually represented.
- Update apps/remark42's engines to node >=18 / pnpm >=10, matching
the pnpm 10 requirement instead of the stale node 16 / pnpm 8 range.
- frontend/Dockerfile.e2e: bump base image to mcr.microsoft.com/playwright:
v1.61.1-noble to match the Playwright 1.61.1 npm bump (browser revision
mismatch was failing all e2e specs), and corepack pnpm@8 -> pnpm@10.10.0 to
match the pnpm bump and the v9 lockfile.
- release.yml validate: pnpm 10 forwards 'test -- --runInBand' literally as
'jest -- --runInBand' (treated as a path pattern, 0 tests). Drop the extra
separator: 'pnpm test --runInBand'.
yarn audit: 0 vulnerabilities (was 52 findings). Site builds via eleventy +
tailwind on node 20.
Direct bumps: markdown-it 14.2, cross-env 10, date-fns 4.4, prettier 3.9,
@tailwindcss/typography 0.5.20, @11ty/eleventy-plugin-syntaxhighlight 5.0.2.
Replaced abandoned html-minifier (unpatched ReDoS, no fix released) with the
maintained html-minifier-terser fork; the .eleventy.js htmlmin transform is now
async. Transitive vulns patched via yarn resolutions. js-yaml resolves to 3.15.0
(3.x backport) which keeps gray-matter working.
Held: tailwindcss 3.4 (tailwind 4 is a config rewrite) and @11ty/eleventy 2
(eleventy 3 is an ESM migration) - both invasive.
Build output verified against a clean master build: every HTML page differs only
by the build-time ?v= cache-bust query; style.css differs only by an equivalent
refactor of @tailwindcss/typography's prose kbd-shadow variables (same rendered
result). Functionally identical.
pnpm 8.15.9 -> 10.10.0 (packageManager + lockfile regenerated to v9). Frontend
CI (ci-frontend.yml, ci-frontend-api.yml, release.yml) and the production
Dockerfile bumped from node 16 + pnpm 8 to node 20 + pnpm 10 (pnpm 10 requires
node 18+). pnpm audit: no known vulnerabilities (was 63 alerts).
packages/api: bumped to latest including the major test stack - vitest 4, jsdom
29, @vitest/coverage-v8 4, @typescript-eslint 8.62, typescript 5.9, prettier
3.9, @types/node 26, and msw 1 -> 2. Migrated tests/test-utils.ts to the msw 2
http/HttpResponse API (capturing a compatible request shape) and made test base
URLs absolute so node 20's native fetch is intercepted; added the jsdom base
URL. type-check:api, lint:api and coverage:api (45 tests) all pass.
apps/remark42: safe in-major bumps (webpack 5.108, postcss, mini-css-extract,
html-webpack-plugin, ts-loader, webpack-dev-server 5.2.5, core-js, clsx 2,
lodash-es 4.18, dotenv 17, @types/*). Transitive vulns patched via
pnpm.overrides. type-check, lint, build, jest coverage (299 tests) and
translations all pass.
pnpm 10's stricter layout required a few pins to keep the app's preact-compat
setup compiling: preact 10.6.2 (override), react-intl 6.0.5 and
@testing-library/preact 3.2.2 (newer types break the build), tsconfig paths for
preact, @types/minimatch 5.1.2 (6.x is an empty stub) and cheerio 1.0.0-rc.12
(1.2 is ESM and breaks jest 28). Held: react/react-dom (preact compat alias),
babel 7, eslint 8, stylelint 14, jest 28, typescript 4.7 (app),
redux/react-redux - majors that change the bundle or need a config migration.
Build output verified against a clean master build: apps/remark42 output is
functionally identical (the only diffs are webpack module-id numbering and
css-module class tokens from the webpack/css-loader bump; all HTML, CSS values
and translations byte-identical).
Update all Go modules in backend/ and backend/_example/memory_store/ to
their latest versions (chroma 2.27, go-redis 9.21, bbolt 1.5, slack 0.27,
golang.org/x/* and others); re-tidy and re-vendor, keep the example module
in sync.
Hold github.com/go-chi/chi/v5 at v5.2.5: v5.3.0 deprecates
middleware.RealIP (IP-spoofing advisories). Switching off RealIP changes
how the client IP is derived for rate limiting and votes, which is a
security decision better made on its own rather than inside a dependency
bump.
go test -race, go vet, golangci-lint and govulncheck all clean on both
modules.
* site: fetch latest version client-side instead of embedding at build time
The header version badge was filled in by site/src/data/github.js calling
the GitHub releases API at Eleventy build time and baking data[0].tag_name
into every page. This had three failure modes:
1. Layered cache: Buildx caches the yarn build layer; on a release-triggered
workflow nothing under ./site changes, so the cached HTML (with the
previous tag baked in) gets shipped. v1.16.0 went out and remark42.com
kept showing v1.15.0 until a separate site/ commit landed and naturally
invalidated the COPY layer.
2. Tag mismatch: the deploy pulls ghcr.io/umputun/remark42-site:master,
but release events build :v1.16.0 and :latest only. A cache-skip
workflow tweak wouldn't even reach the served image.
3. API propagation race: the workflow fires ~2s after release publish,
so even with cache disabled the API might still return the previous
tag from a stale read replica.
All three vanish if the version is fetched in the browser. GitHub serves
the /releases/latest response with Cache-Control: public, max-age=60 so
per-visitor cost is bounded; failures fall through silently and the
badge stays empty rather than wrong.
Changes:
- header.njk: replace {{ github.latestVersion }} with a
<span data-remark42-version></span> placeholder.
- inline.js: add a fetch of /releases/latest that fills any
[data-remark42-version] element on the page. fallback is no-op on any
network/parse failure.
- delete site/src/data/github.js (Eleventy data file is no longer used).
- drop node-fetch from devDependencies (was used only by github.js).
* site: address PR review on version badge fetch
- gate DOM update on DOMContentLoaded — inline.js is loaded sync in <head>,
so a cache-hit fetch can resolve before the placeholder span is parsed.
- hide placeholder span by default (`hidden`) so a failed/blocked fetch
doesn't leave a 0.5rem stray gap before the github icon.
- log fetch failures (rate limit, offline, blocked) instead of silently
swallowing — matches the prior behaviour of build-time github.js.
* site: cache latest version in sessionStorage with 1h TTL
avoids hitting the GitHub API on every page load — repeated navigations
within a tab read from sessionStorage instead. TTL caps stale display at
1h for very long-lived tabs. cleared on tab close, so each new session
fetches once and reuses the result throughout.
* site: address PR review on header & version fetch
Copilot review on the cache commit raised three points:
1. inline.js had a hard-coded `https://api.github.com/repos/umputun/remark42`
while the templates use `site.githubUrl`. Rename inline.js → inline.njk
so nunjucks evaluates it, add `githubApiUrl` to site.json, and template
the fetch URL from it. One place to update if the repo ever moves.
2. header.njk aria-label said "Remark42's GitHub Repository" but the link
target is `/releases`. Change to "{{ site.name }} releases on GitHub"
so screen readers describe the actual destination.
3. console.warn on fetch failure (kept after umputun's prior review noted
the trade-off): addressed in the PR description, no code change.
* site: actually template fetch URL via site.githubApiUrl
Copilot's second pass caught that 7697dcf3 added site.githubApiUrl,
renamed inline.js → inline.njk, and pointed head.njk at the .njk file
— but the fetch() call itself was never changed to use the template
variable. Build output looked correct because the literal hard-coded
URL happened to match what {{ site.githubApiUrl }} would expand to.
* site: normalise Nunjucks spacing in header.njk
{{ site.githubUrl}}/releases → {{ site.githubUrl }}/releases. Cosmetic
only; matches the spacing used everywhere else in the templates.
* fix(frontend): no_footer scrollbar regression introduced in v1.16.0
Two unrelated changes in v1.16.0 combined to surface a scrollbar in
no_footer=true mode:
1. c26f45e5 removed the deprecated `scrolling="no"` iframe attribute
on the grounds that "overflow is already hidden via CSS". That CSS
(`overflow: hidden` in createIframe styles) is on the iframe ELEMENT
in the parent page; it has no effect on the iframe DOCUMENT's own
scrollbars. The spec-correct replacement is `overflow: hidden` on
the iframe document's body — added here to global.css.
2. The negative `margin-bottom: -24px` on `.thread:last-child` was a
trick to tighten the gap to the footer (combined with the footer's
`margin-top: 48px` it collapsed to a 24px net gap). With no_footer
the negative margin had no positive-margin sibling to collapse
against and instead propagated up through .root, leaving body
~24px shorter than the visual content. The iframe height calc
(`body.offsetHeight + 12`) then sized the iframe below the visible
bottom of the last thread → scrollbar.
Replace the negative-margin trick with a straight `margin-top: 24px`
on `.copyright`. Same 24px visual gap when the footer is shown, no
propagation when it isn't. The mix={styles.thread} on Thread becomes
a dead reference and is dropped.
Closes#2073
* fix(frontend): drop dead Thread.mix prop after root.tsx removed its only caller
Both Copilot and umputun flagged this in PR review: after the parent
commit on this branch dropped `mix={styles.thread}` from root.tsx, the
`mix?: string` prop and the corresponding entry in the clsx() call in
thread.tsx are dead code — no caller passes it (the recursive Thread
render in thread.tsx:82 never did either). Remove the prop, the
destructure, and the clsx entry.
* fix: address parameter docs and --help text inconsistencies
Audit findings from comparing site/src/docs/configuration/parameters/
against the backend flag tags.
Docs (parameters/index.md):
- image.bolt.file default was `/var/pictures.db` (absolute, looks like
a system path); actual default is `./var/pictures.db` (relative,
under the working dir).
- notify.webhook.template default was shown as
`{"text": {{.Text | escapeJSONString}}}` — both the function name
doesn't exist and the unescaped pipe inside the table cell broke the
Description column count for that row. Real default is the literal
`{"text": "{{.Text}}"}`.
- "Custom OAuth2 integration currently supports only one custom
provider at a time" was a free-standing paragraph wedged between two
table rows. kramdown terminated the table on that paragraph and
restarted a new headerless table for the rest of the rows. Moved it
to its own subsection after the table so the table stays contiguous.
Backend --help text (server.go):
- allowed-hosts description ended with a stray double apostrophe in
`CSP 'frame-ancestors''` (typo).
- Deprecated auth.email.{port,passwd,user,tls} flag descriptions were
shuffled — port said "SMTP password", passwd said "SMTP port", user
said "enable TLS", tls said "SMTP TCP connection timeout". Fixed
each to match the flag it's actually describing. Docs already had
the correct descriptions for these deprecated flags.
* fix: webhook template flag default override masking safe fallback
Copilot flagged the audit's "real default" claim and was right. server.go:286
had default:"{\"text\": \"{{.Text}}\"}" — the literal, JSON-unsafe template
that produces invalid JSON if a comment contains a quote or newline. The
notify package (webhook.go:50) has a safer fallback:
if params.Template == "" {
params.Template = webhookDefaultTemplate
}
where webhookDefaultTemplate is {"text": {{.Text | escapeJSONString}}}. But
go-flags applies its default tag at parse time, so the field is never empty
when the user omits --notify.webhook.template, and the safer fallback never
runs.
Drop the unsafe default tag so the webhook package's escapeJSONString-based
default takes effect. Also:
- fix the --help description (was "webhook authentication template", but
it's a payload template, not an auth one; same for headers).
- update parameters/index.md to document the actual safe default
({{.Text | escapeJSONString}}); escape the cell's | as \| so kramdown
doesn't treat it as a column separator.
- typo: "bellow" -> "below" in the headers env-delim comment.
opening backtick had no closer in the Default column, so kramdown saw a
broken cell and stopped rendering the parameters table — every row from
smtp.login_auth onward (~40 rows) rendered as raw pipe-delimited text
instead of HTML table cells. closes#2074
replace the Docker artifact build with GoReleaser config and a tag release workflow. Keep local artifact builds snapshot-only and clean generated frontend embed files after release runs.
* fix(security): reject non-image content-types in image proxy and /picture/ to prevent stored XSS
The /api/v1/img proxy and /api/v1/picture/{user}/{id} endpoints emitted
http.DetectContentType on the served bytes as the response Content-Type. A
controlled upstream serving Content-Type: image/png with an HTML body passed
the upstream check (only the response header was inspected, not the body),
and the body bytes then sniffed back to text/html — so the proxy served the
attacker's HTML from the remark42 origin. Browsers honoured the declared
text/html and executed the response as a document with access to cookies and
CSRF tokens. Affected from v1.6.0 (April 2020) through v1.15.0; verified live
via published docker images.
Layered defense applied to both handlers:
- rest.SafeImgContentType (in backend/app/rest/) validates sniffed content
against a strict allowlist: image/png, image/jpeg, image/gif, image/webp,
image/bmp, image/x-icon. Anything else (HTML, XML, SVG, plain text,
octet-stream, or any future image type the stdlib sniffer may learn) is
rejected with no body echo. SVG is implicitly excluded — it sniffs as
text/xml or text/plain, never image/svg+xml, and SVG can execute scripts
when navigated to top-level. The previous octet-stream → image/* fallback
is gone.
- Per-endpoint Content-Security-Policy override sets
"default-src 'none'; sandbox; frame-ancestors 'none'" on every response
(success, 304, or error). Sandbox neuters scripts even if Content-Type
ever regresses. The same policy is also applied to all /api/v1/* via
apiCSPMiddleware as defense-in-depth.
- Content-Disposition: inline; filename="image" frames the response as a
file rather than a renderable document.
- /picture/ rejection paths set Cache-Control: no-store so 4xx responses
are never cached.
The defense headers and the strict ETag matcher are extracted as
rest.SetImageDefenseHeaders and rest.EtagMatches in the shared rest package
(consumed by both proxy/image and api/rest_public — no package cycle).
The /api/v1/img path additionally bumps the ETag to a versioned `"v2:..."`
so revalidating clients (top-level navigation, Ctrl+R, intermediaries) get
a fresh 200 instead of a 304 against poisoned pre-fix cached HTML.
DELIBERATE TRADEOFF: Cache-Control on /api/v1/img success responses remains
max-age=2592000 (30 days), unchanged from before. An aggressive "force
revalidate on every reuse" policy was prototyped during review but reverted
because the perf cost (a server round-trip on every image view, even with
304 saving the body bytes) outweighed the corner-case mitigation. The
realistic exposure of cache carryover is narrow: cache carryover only
affects users who navigated top-level to an attacker URL pre-fix and still
have it in their local cache — the normal <img> embed path cached text/html
but never executed it. Local browser caches that hold pre-fix bytes
continue to serve them until their 30-day TTL expires or are evicted under
memory pressure. The ETag bump reaches all clients that DO revalidate
during the cached lifetime (Ctrl+R, intermediaries, post-expiry use); for
the rest, exposure self-limits via cache expiry. Operators running a
CDN/edge cache in front of remark42 should purge /api/v1/img after deploy.
The /api/v1/img handler short-circuits on a matching current-version
If-None-Match before any store Load or upstream fetch, returning a bodyless
304 with the defense headers set. Safe because the 304 carries no body and
the client's cached bytes came from a prior validated 200; an attacker
fabricating an etag value can only short-circuit fetches for URLs they
themselves crafted. This avoids upstream DoS amplification when clients
revalidate on hot comment pages.
The /api/v1/img route was moved from the "open routes" group (which uses
middleware.NoCache, stripping If-None-Match from incoming requests) to the
"open routes, cached" group alongside /picture/ and /qr/telegram so the
304 revalidation path is no longer broken upstream of the handler.
The /picture/{user}/{id} endpoint does not need the v2 etag prefix. Upload
validates input format via readAndValidateImage and the serve path
re-validates the stored bytes via rest.SafeImgContentType. Bytes within
the resize dimension limits are preserved verbatim, so the browser defense
relies on the response headers (validated Content-Type + nosniff + strict
CSP + Content-Disposition: inline), not on byte normalization.
Global CSP: font-src data: → font-src 'none'. Audit confirmed no @font-face,
no base64 fonts, no icon-font library in the bundle. Drops an unnecessary
attack surface; no behavioural change.
Tests: TestImage_ContentTypeHandling table-tests a real PNG and attack
shapes (HTML claimed as image/png, image/jpeg, image/gif, image/svg+xml,
image/webp; svg with onload; html fragment; polyglot PNG+HTML), proving
the defense holds across arbitrary upstream Content-Type variation.
Polyglot case is intentionally served as image/png — the browser cannot
execute the trailing HTML when the response type is image/png with nosniff.
TestImage_ContentTypeHandling_CacheHit exercises the cache-hit branch with
attacker bytes preloaded into the store. TestImage_PerRequestRevalidation
alternates upstream PNG/HTML across four proxy calls to prove no trust
accumulates between requests. TestImage_RoutesUsingCachedImage asserts
cache-poisoning is caught at serve time. TestImage_EtagVersioned asserts
the v2 prefix invalidates pre-fix etags AND that the revalidation 304
triggers no store Load. TestImage_RevalidationSkipsIO proves the
short-circuit works even with no upstream reachable. TestSafeImgContentType
covers the allowlist directly. TestRest_LoadPictureDefenseHeaders and
TestRest_LoadPictureRejectsNonImage exercise the /picture/ endpoint.
TestRest_apiCSP covers the strict CSP middleware on JSON API + RSS routes;
TestRest_securityHeaders confirms /web/ HTML pages keep the global CSP.
Verified end-to-end against the dev docker image: the original demo URL
(arbitrary HTML claimed as image/png) now returns 415 application/json with
CSP/nosniff/Content-Disposition set, no XSS in the browser.
* fix(security): set Cache-Control: no-store on image-proxy error paths, sync stale route comment
Addresses two review comments on #2067:
1. Cache-Control: max-age=2592000 and Etag were set before the
load/download/validation block, so 404/400/415 error responses inherited
the 30-day cache TTL and the versioned etag — a transient failure (or an
intentionally triggered 415) would be pinned in browser/intermediary
caches for that TTL, keeping users locked out even after the underlying
cause was resolved. Now: etag is computed but not set as a header until
after validation succeeds; error paths route through sendImageProxyError
which sets Cache-Control: no-store and never sets Etag. The 304
short-circuit still sets both because that path serves the same validated
content the client already has cached.
2. The comment at rest.go:282 still described the prototyped
no-cache/must-revalidate Cache-Control policy that was reverted before
the PR landed. Updated to match the actual 30-day max-age behavior.
Tests: TestImage_ContentTypeHandling now asserts reject paths carry
Cache-Control: no-store and have no Etag header, and accept paths carry
the max-age=2592000 + v2: etag.
readAndValidateImage caps the byte size of incoming images but the resize()
helper that follows still called image.Decode unconditionally, allocating
pixel memory proportional to the *declared* image dimensions. A ~100 KB
compressed PNG or GIF that declares 65535x65535 px forces image.Decode to
allocate ~17 GB of raster, OOMing the service on a single comment upload
(or on the proxy's CacheExternal path when caching a malicious upstream).
Hardening:
- maxImagePixels = 16 MP constant. Covers any realistic image (~4096x4096)
while bounding peak allocation.
- resize() now runs image.DecodeConfig first (cheap, no pixel allocation)
to read declared width/height before any full decode.
- Multiplication of width × height uses int64 to defeat 32-bit overflow
(GOARCH=386, 32-bit arm): on those targets, int(cfg.Width)*int(cfg.Height)
could wrap below maxImagePixels and bypass the cap. GIF's 16-bit logical
screen and JPEG's 16-bit SOF dimensions both reach this if int-multiplied.
- Bytes exceeding the cap, or non-image input that fails DecodeConfig,
return nil. prepareImage propagates the rejection as a clear error
instead of storing the malformed/oversized data verbatim.
- The no-resize-needed path returns the validated original bytes verbatim
so animated GIFs round-trip without being flattened to a single frame.
The DecodeConfig precheck applies even when MaxWidth/MaxHeight are 0
(resize disabled) — the dimension cap is unconditional defense-in-depth.
Two adjacent fixes surfaced by the new resize contract:
1. readAndValidateImage previously did `data[:512]` without a bounds check,
panicking on any body shorter than 512 bytes. Now bounded with min().
2. image/webp was listed as an allowed format but no WebP decoder was
registered, so DecodeConfig would refuse legitimate WebP uploads. Added
`_ "golang.org/x/image/webp"` (already in go.mod via x/image/draw) so
the registered decoders match the allowlist.
Tests:
- TestService_resizeRejectsDecompressionBomb builds a 14-byte GIF87a header
declaring 65535x65535 and asserts resize() refuses it both at the unit
level and through SaveWithID end-to-end (no store write).
- TestService_SaveWithIDShortPayload regression-tests the short-body panic.
- TestService_SaveWithIDWebP regression-tests WebP round-trip through
prepareImage with the new DecodeConfig requirement.
- TestService_resize subtests updated to assert non-image bytes are now
refused (previously the helper fell back to returning the raw bytes
verbatim, letting malformed content reach the store).
Mention the "Report a vulnerability" button (GitHub private vulnerability
reporting) alongside the existing email contact, now that private reporting
is enabled on the repository.
* Probe /auth/status from frontend to avoid 401 console noise on /user
GET /api/v1/user requires auth and returns 401 for anonymous visitors,
which the browser logs to console even when JS catches it. Probe
/auth/status first (always 200), then fetch /user only when logged in.
Stale auth cookies are cleared when status reports "not logged in" to
preserve the cleanup-on-probe behaviour previously triggered by /user 401.
Closes#1188.
* Don't clear auth cookies when /auth/status probe itself fails
A transient network/5xx on the /auth/status probe used to fall through
into the cookie-clear branch and silently log the user out on the next
page load. Distinguish "probe failed" (null) from explicit "not logged
in"; only the latter clears JWT/XSRF cookies. Lock the distinction with
a negative assertion in the probe-failure test.
Also align packages/api prettier config with apps/remark42 (trailingComma: 'es5')
so future edits don't sweep unrelated trailing commas into the diff.
* fix(auth): close OAuth open-redirect by wiring AllowedRedirectHosts
Bump go-pkgz/auth/v2 to master (v2.1.2-0.20260421203319-686683f19cf7)
which carries the `from` redirect validator from go-pkgz/auth#275.
The library default with a nil AllowedRedirectHosts is permissive
(preserves legacy behavior for existing consumers on a dep bump), so
just bumping the dep leaves remark42 vulnerable — a crafted
/auth/<provider>/login?from=https://evil.example.com/... still issues
the 307 to the attacker host after the user completes legitimate
OAuth. Verified end-to-end against a local dev-auth instance before
and after this commit.
Wire Opts.AllowedRedirectHosts in getAuthenticator to the operator's
existing --allowed-hosts config, stripping the CSP "self" sentinel
which is not a real hostname. RemarkURL's own host is always implicit
per the library contract, so a default single-site deployment gains
the protection with no config change. Multi-host embeds work as soon
as their embedding hosts are added to AllowedHosts (they already need
to be there for CSP frame-ancestors).
Refreshed vendor tree to match the new module version.
* chore(lint): suppress G703 false positives on image Save
CI's newer gosec flags os.MkdirAll/os.WriteFile in FileSystem.Save with
G703 because id flows in from the caller. id is validated at the HTTP
layer (safePictureSegment in rest_public.go) and dst is derived via
f.location — not a real traversal. Targeted //nolint with reason.
* fix(auth): normalise AllowedRedirectHosts entries + add unit test
Address Copilot review on PR #2049. The previous closure passed raw
s.AllowedHosts entries straight to the auth library, but --allowed-hosts
holds CSP frame-ancestors source expressions: scheme-prefixed values
(https://blog.example.com), entries with ports, and wildcards
(*.cdn.example.com) are all valid there but the auth library compares
against u.Hostname() and would silently drop them — breaking legitimate
redirects on multi-host deployments.
Extract getAllowedRedirectHosts that:
* trims whitespace, drops empty / 'self' / "self" / wildcard entries
* prepends https:// if scheme missing then url.Parse to extract Hostname
* logs a warning on parse failure rather than poisoning the allowlist
Wire the closure in getAuthenticator to call the helper.
Test_getAllowedRedirectHosts covers all the edge cases Copilot flagged
(scheme stripping, port handling, self spellings, wildcards, empty,
mixed real-world).
* fix(auth): preserve explicit port in AllowedRedirectHosts + clarify fs_store nolint
Address Copilot follow-up on PR #2049:
* getAllowedRedirectHosts stripped explicit ports via u.Hostname(), which
broadened the allowlist. The auth validator checks both Hostname() and
Host, so an entry like admin.example.com:8443 can and should be kept
host:port — allowing only that port, not any. Emit u.Host when
u.Port() != "", u.Hostname() otherwise. Updated tests.
* fs_store Save nolint rationale said "id validated at HTTP layer", but
Save is reached via image.Service.Save and SaveWithID (cache), neither
of which is HTTP validation. id is actually a server-generated hash in
both paths. Updated the comment.
Go 1.25's testing/synctest package (GA) provides a fake clock bubble
for deterministic goroutine and timer testing. Convert tests that
waited on real-time durations to use synctest, removing most wall-clock
time.Sleep workarounds.
Converted (11 tests, 9 files):
- notify/notify_test.go — all tests, replaced 17 time.Sleep(110ms) with synctest.Wait()
- store/service/service_test.go — VoteSameIPWithDuration, UserReplies, submitImages,
ResubmitStagingImages, deleteImagesOnCommentDelete
- store/image/{image,bolt_store}_test.go — Cleanup, Submit, SubmitDelay
- store/engine/bolt_test.go — FlagListBlocked
- providers/telegram_test.go — DispatchTelegramUpdates
- migrator/backup_test.go — TestBackup_Do
- _example/memory_store/accessor/data_test.go — FlagListBlocked
Simplifications along the way:
- notify/notify_mock.go: dropped the 10ms time.After delay and
ctx.Done select in MockDest — the artificial I/O simulation is
pointless and blocked synctest.Wait from draining the queue
- Removed three dead-code time.Sleep(1s) calls in EditCommentDurationFailed,
EditCommentAdmin, and Info tests: prepopulated comments from 2017
already exceed any EditDuration/ReadOnlyAge under real clock, making
the sleeps meaningless
- UserReplies: replaced the Eventually+Sleep+mutex polling with a
direct time.Sleep under fake clock
Skipped (incompatible with synctest):
- fs_store_test.go: relies on OS file mtime (real wall clock)
- rss_test.go: needs real wall-clock second boundary for pubDate
- admin/rest_private/rest_public tests: httptest network I/O
- cmd/server_test.go: real HTTP server startup polling
Notes on quirks encountered:
- synctest.Wait() does NOT advance fake time, contrary to what one
might expect. It only returns once all other bubble goroutines are
durably blocked. To advance the fake clock, the test goroutine must
itself call time.Sleep
- BoltDB keys the "last" bucket by comment.Timestamp nanosecond string.
Rapid b.Create calls under frozen fake time produce identical keys
and overwrite each other. TestService_UserReplies adds
time.Sleep(time.Nanosecond) between Creates to advance the clock
- Bolt image Cleanup uses strict age > ttl. Under fake time the
age-ttl delta is exactly zero at the boundary, so subtract 1ms from
the passed ttl to stay strictly under

RemarkURL from CLI flags (not user input); migrator.go removes a temp
file whose name was returned by os.CreateTemp (server-controlled). Add
targeted //nolint:gosec comments naming the reason at each site.
Commit aca0cff3 silenced the path-traversal, SSRF and XSS taint rules
project-wide as "false positives" while fixing image-proxy SSRF. With
the path-traversal and TitleExtractor SSRF gaps now closed, restore the
rules so future regressions get flagged. The four genuine false positives
that remain (image proxy http.NewRequest, QR png Write, two RSS XML
Writes) get individual //nolint:gosec comments naming the reason.
The image proxy got an ssrfSafeTransport in commit aca0cff3 that resolves
DNS first, blocks any IP in private/reserved CIDRs, then dials by IP to
defeat DNS rebinding. The TitleExtractor used to construct comments'
PostTitle from Locator.URL — a user-supplied field — was missed by that
fix and kept using http.DefaultTransport. The hostname allowlist there
checks the parsed URL host but never the IP it resolves to, so a domain
suffix-matching an allowed host (or 127.0.0.1 itself when AllowedHosts
is empty) reaches the metadata service or any other internal endpoint.
The same gosec rule (G704) was excluded globally in .golangci.yml as part
of aca0cff3, so this gap was not caught by the linter either.
Extract the transport into a new safehttp package so it lives in one
place and can be reused, then pass safehttp.Transport() into the
TitleExtractor's http.Client at construction (cmd/server.go). The image
proxy switches to safehttp.Transport() too — same behaviour, no longer
duplicated.
Reproduction in title_test.go uses the production-style client to hit
an httptest.Server (always 127.0.0.1) and asserts the dialer refuses
even though "127.0.0.1" is in the allowed-domains list. A control case
shows the same setup without safehttp.Transport returns the page —
making the original vulnerability explicit.
Address PR #2045 review (umputun):
* The //nolint:gosec on telegramQrCtrl's w.Write(png) was byte-identical
to the same line in #2044 (gosec-rule restoration). Drop it here so
the two PRs do not conflict; #2044 owns it.
* `seg == ".."` in safePictureSegment was already covered by the
strings.Contains(seg, "..") check two lines down — trim and add an
inline comment so the cover-by-superset is explicit.
Address PR #2045 review feedback (Copilot #2045-1). The previous
safePictureSegment allowed CR/LF/TAB through, so a request such as
GET /api/v1/picture/dev%0Auser/abc.png would inject literal newlines
into the access log line ("GET - /api/v1/picture/dev\nuser/abc.png ...")
— a log-forgery primitive against any operator parsing those logs.
Reject any unicode.IsControl rune in either segment (NUL was already
caught via strings.ContainsAny). New TestRest_LoadPictureRejectsControlCharsInSegment
covers LF, CR, TAB, NUL across both segments.
The unauthenticated GET /api/v1/picture/{user}/{id} handler concatenated the
two URL params verbatim into a filesystem path via path.Join, so a request
like /api/v1/picture/../remark.db resolved to <base>/../remark.db, escaping
the image directory. With Partitions=0 (a documented option) this is a
direct arbitrary-file read; with the default Partitions=100 the constructed
path lands in a CRC-derived subdirectory but the server still leaks the
internal filesystem path back to the unauthenticated caller via the JSON
error body — confirmed against demo.remark42.com (master-80c12a3) which
returned `stat /var/folders/.../staging/.../remark.db` for `..` requests.
Validate both URL segments via safePictureSegment (no traversal markers,
no path separators, no NULs) at the handler entry, and replace the raw
storage error with a generic "image not found" response. The original
error is logged for operators.
Reproduction test asserts that ../remark.db, foo/..%2Fremark.db and
%2E%2E/remark.db all return 400 with no internal path leaked.
The store tests stored timestamps with time.Local in their fixtures and
asserted equality against returned values that the engine round-trips
through UTC. assert.Equal compares zone identity, so on UTC machines
(CI, most cloud envs) Local==UTC and the tests passed; on a developer
machine in any other timezone (here BST, UTC+1) TestService_Put,
TestService_List, TestBoltDB_InfoPost, TestBoltDB_InfoList and several
others would fail with same wall-clock numbers but mismatched zones.
Replace time.Local with time.UTC across store/comment_test.go,
store/formatter_test.go, store/service/service_test.go,
store/engine/bolt_test.go, store/engine/engine_test.go. Production code
is untouched.
matchSiteID guarded most authenticated and admin routes with
`if siteID != "" && user.SiteID != siteID`. Dropping the ?site= query
parameter made the check no-op and any authenticated user passed the
middleware. Downstream handlers fell back to reading site from the JSON
body or just used the empty string, so on email/telegram subscribe
endpoints (which read site from body) a user authenticated to siteA
could perform actions targeting siteB without the cross-site guard
ever firing.
Require ?site= to be present and to match user.SiteID. Body-only site
flows are still supported provided the URL also carries the matching
?site= — both must agree, which removes the bypass and keeps the
declared site visible to the middleware.
Reproduction TestRest_matchSiteID enumerates four cases (matching,
mismatched, missing, empty). Existing test calls that relied on the
implicit pass had to add ?site=remark42 to the URL: the addComment
helper now derives the param from c.Locator.SiteID, picture upload
URL gets the param explicitly, and the email/telegram subscribe table
adds it to every endpoint. The negative cases that previously asserted
StatusBadRequest from the handler now correctly assert StatusForbidden
from the middleware.
* fix(embed): set color-scheme on iframe to fix Firefox dark mode
Firefox renders a white background in dark mode when color-scheme is 'none' on the iframe. Set color-scheme to match the active theme on both the outer iframe element and the inner document root, so Firefox uses the correct rendering mode from the start and on theme changes.
* fix(embed): default iframe color-scheme to light when no theme set
Changes the fallback from 'light dark' to 'light' to match the inner document's default behavior, which always defaults to light when no theme is specified.
The edit textarea was running `data.orig` through the browser's HTML
parser via a detached `<span>.innerHTML` to "decode entities", which
turned user-typed `<`/`>` into real `<`/`>`. On save, blackfriday
then saw a real `<script>` tag, bluemonday stripped it, and the comment
body collapsed to an empty string.
The decode block predates commit 243c835 (2022) which stopped the
backend from sanitising `orig` with bluemonday. Before 243c835, orig
came back HTML-escaped from the API and the frontend compensated.
After 243c835 the backend stores and returns orig byte-for-byte, but
the frontend decode was never removed — so it has been silently
corrupting user input containing entities for ~3.5 years.
The backend contract is clear: `orig` is the raw user input, never
rendered as HTML. The frontend should echo it back into the textarea
unchanged. This change removes the decode and adds 45 table-driven
regression tests covering entity round-trips, unicode edge cases,
and markdown constructs.
Bump Go dependencies in both backend/ and backend/_example/memory_store.
Notable updates:
- github.com/go-pkgz/lgr v0.12.1 -> v0.12.3

- golang.org/x/sys v0.41.0 -> v0.43.0
- golang.org/x/{oauth2,sync,text} minor bumps
Key markdown/sanitisation libs (bluemonday v1.0.27,
alecthomas/chroma/v2 v2.23.1, russross/blackfriday/v2 v2.1.0,
Depado/bfchroma/v2 v2.0.0) are already at the latest available
versions and were not bumped.
Verified the Chroma span-class allowlist regex in
backend/app/store/comment.go:128-131 is still fully in sync with
chroma/v2 types.go StandardTypes map (86 classes, byte-equal after
sorting). The inline comment references commit c263f6f which is
stale (Chroma is at v2 now), but the class list content is current.
Ran `go mod tidy` + `go mod vendor` + full race test suite on both
modules. All green. Added a reminder in CLAUDE.md that updating
backend/ Go modules also requires `go mod tidy` in
backend/_example/memory_store since the example module uses a
local replace directive and inherits indirect deps from the main
module.
Consolidate legacy BEM CSS files into CSS Modules for 4 components:
- dropdown/__item: 1 CSS file → dropdown-item.module.css
- list-comments: 1 CSS file → list-comments.module.css (removed unused
comments-list class that had no CSS rules)
- comment-form/__subscribe-by-rss: 1 CSS file → subscribe-by-rss.module.css,
removed dead titleClass prop and dead __rss-link directory
- settings: 10 CSS files → settings.module.css, removed dead
.settings__blocked-users-username CSS rule
Built artefact comparison (master vs branch):
- 83 of 89 files in /srv/web/ are byte-identical (all locale bundles,
SVGs, HTML pages unchanged)
- 6 files differ: remark.css/js/mjs and last-comments.css/js/mjs
- CSS changes are class name hash shifts (e.g. G_A → H_A) caused by
webpack's module ordering, plus 3 new var() fallback values added
by the CSS modules build; all property:value pairs are preserved
- JS changes are minified variable name shifts (O ↔ A, I ↔ L) from
changed import order; no logic changes
- Visual comparison (pixel-by-pixel screenshots of both light and dark
themes on the demo page) shows 0 different pixels
- Bundle sizes: remark.css -626 bytes, remark.js -512 bytes,
last-comments.css -16 bytes (dead CSS removed)
* frontend: remove deprecated iframe attrs and non-standard CSS
Three separate cleanups:
1. remove deprecated HTML attributes from iframe creation (create-iframe.ts)
- frameborder="0": deprecated since HTML5; border is already set to none via CSS
- allowtransparency="true": non-standard Microsoft attribute never in any spec;
transparency is handled by body { background: transparent } in CSS instead
- scrolling="no": deprecated since HTML5; overflow is already hidden via CSS
- horizontalscrolling/verticalscrolling: non-standard IE-era attributes with
no effect in modern browsers; remove without replacement
2. replace allowtransparency with explicit CSS (global.css)
- add background: transparent to body; this is the spec-correct way to make
an iframe document transparent, as documented by MDN
3. drop -moz-touch-enabled media query prefix (5 comment CSS files)
- -moz-touch-enabled was a Firefox-only non-standard media feature removed
in Firefox 58 (2018); pointer: coarse is the standard equivalent and was
already present as the second condition in every query, so removing the
dead -moz prefix reduces the media query to just (pointer: coarse)
note: colorScheme: 'none' in create-iframe.ts is intentionally left unchanged;
it is tracked by #1430 and requires a broader color-scheme implementation
* frontend: fix CSS bugs and replace deprecated properties
Bugs fixed:
- comment-votes.module.css: add missing comma between transition values;
without it the shorthand was invalid and colour transitions on vote
buttons were silently ignored
- icon-button.module.css: fix "transfrom" typo (should be "transform");
the misspelling made the transition declaration a no-op, so the hover
scale animation jumped instantly instead of easing
- auth.module.css: remove doubly-nested rgb(rgb(var(…))) call; the outer
rgb() rejected the inner rgb() result, so the .title element's colour
fell back to inherited instead of the intended --secondary-text-color
Deprecated properties replaced:
- comment-form__markdown-toolbar.css: replace deprecated clip: rect()
with clip-path: inset(50%); clip was deprecated in CSS Masking Level 1
- raw-content.css: replace word-wrap with overflow-wrap; word-wrap was
renamed in CSS Text Level 3, all current browsers support overflow-wrap
- global.css: remove redundant literal-colour fallback lines before
var() declarations in .preloader and .preloader_view_iframe; the var()
calls already have inline fallback values (e.g. var(--color6, #fff)),
making the preceding duplicate property and its stylelint-disable
comment unnecessary since IE11 EOL
* move border:none from inline style to widget__comments-frame class
Apply go fix ./... analysers (Go 1.26) across backend and examples:
- interface{} → any (type alias, no behaviour change)
- for i := 0; i < N; i++ → for range N / for i := range N
- slices.Contains / slices.ContainsFunc replacing manual loops
- strings.SplitSeq replacing strings.Split in range (avoids allocation)
- strings.CutPrefix replacing HasPrefix+TrimPrefix
- min() replacing manual if/else
- fmt.Appendf replacing []byte(fmt.Sprintf(...))
- strings.Builder replacing string += concatenation
- wg.Go(func(){}) replacing wg.Add(1)/go/wg.Done() pattern
- removed redundant ii := i loop variable copies (unnecessary since Go 1.22)
omitempty on struct-typed JSON fields: go fix removed omitempty from
struct-typed fields (time.Time, PostInfo, UserDetailEntry) because
encoding/json's omitempty never applied to struct types — it was always
a no-op. Kept as bare tags (no omitzero replacement) to preserve the
existing serialisation behaviour.
Add skipLibCheck to skip type checking of .d.ts files in node_modules,
matching the setting already used by the main remark42 app. Fixes
@types/eslint-scope vs @types/eslint type incompatibility.
Replace manual actions/cache steps with built-in setup-node cache support.
Add cache: pnpm and cache-dependency-path to all setup-node steps in both
ci-frontend.yml and ci-frontend-api.yml. Move pnpm install before setup-node
as required for pnpm caching to work.
Replace strings.Split(RemoteAddr, ":") with net.SplitHostPort for correct
IPv6 address extraction in vote deduplication and comment IP tracking.
Harden image proxy: add SSRF-safe transport blocking private/reserved IPs
at connection time with DNS rebinding protection, sanitize error messages
to prevent information leakage, add response size limit via io.LimitReader.
Fix shadowed error variables in BlockedUsers, SetTitle, and Delete methods.
Exclude gosec taint analysis false positives at linter config level.
Clarify that any content placed inside the `<div id="remark42">` is
automatically removed once the iframe signals it has initialised.
Update all code examples across getting-started, frontend config, and
Astro/Gatsby integration guides to use "Comments loading..." as the
placeholder so the feature is visible by default.
Deploy jobs only curl an external updater URL and need no GitHub API
access. Without an explicit permissions block they inherit the workflow
default, which may include contents:write, packages:write, etc.
Setting permissions to {} limits the blast radius if a job is
compromised.
Add two missing security headers to the existing securityHeadersMiddleware:
- X-Content-Type-Options: nosniff — prevents browsers from MIME-sniffing
responses away from the declared Content-Type, stopping e.g. a
user-uploaded image from being reinterpreted as executable HTML/JS
- Referrer-Policy: strict-origin-when-cross-origin — limits URL information
leaked in the Referer header on cross-origin requests to just the origin
(no path), and sends nothing at all on HTTPS-to-HTTP downgrades
Add AUTH_MICROSOFT_TENANT env var to allow configuring the Azure AD
tenant for single-tenant Entra ID applications, which cannot use the
default /common endpoint.
Depends on go-pkgz/auth#266
Closes#1998
Remove non-iframe child nodes from the root element once the
iframe signals it has initialised, allowing users to add
loading placeholders that get cleaned up automatically. Fixes#1990
Add admin_edit field to frontend Config types and use it in
comment component to give admins unlimited edit time and allow
editing comments with replies. Hide countdown timer when
editDeadline is Infinity. Fixes#1986
When EditDuration is zero or negative, cleanupTTL becomes zero,
causing time.After(0) to fire immediately in a tight loop.
Block on ctx.Done() instead when edit duration is disabled. Fixes#1991
The paths filter was applied to tag events, preventing site rebuilds
when releases don't include site changes. Switch to release event
trigger which always fires on new releases, ensuring the site fetches
the latest version from GitHub API.
Closes#1992
Replace WriteHeader() + RenderJSON() pattern with EncodeJSON() which
properly sets Content-Type header before writing status code. The
previous pattern caused Content-Type to default to text/plain instead
of application/json, breaking frontend JSON parsing.
Fixes#1979
Replace QEMU emulation with GitHub's native ARM64 runners for faster builds:
- Use ubuntu-24.04-arm for ARM builds instead of QEMU emulation
- Split build job into matrix for parallel platform builds
- Add digest-based workflow for multi-arch manifest creation
- Keep build-test on ARM64 runner for faster PR verification
The last step of the data deletion feature–when the admin user visits the link sent by the user requesting to delete their data–was broken due to the deleteme.js script not being loaded.
* 1833 - Toolbar buttons are stuck to the main comment form
* Add readonly and JSDoc to CommentForm textareaId properties
Improve code quality based on review feedback: mark textareaId as
readonly since it should never change after construction, and add
JSDoc to static textareaCounter explaining its purpose.

Fixes#1957
Replace go-chi/render with go-pkgz/rest for JSON responses and custom
helpers for HTML/plain text responses.
Key changes:
- Replace render.JSON/render.Status with rest.RenderJSON and explicit
w.WriteHeader() calls
- Replace render.DecodeJSON with json.NewDecoder().Decode()
- Add SendErrorJSON helper that sets Content-Type header before
WriteHeader (required since rest.RenderJSON can't set headers after
WriteHeader is called)
- Add HTMLResponse and PlainTextResponse helpers
Fix export double-execution in migrator.go:
The original code called Export twice - once to io.Discard to check for
errors, then again to actually write. This was wasteful and had a race
condition risk. Now file mode buffers to memory first for atomic
success/failure, while stream mode writes directly with proper error
handling.

Addresses discussion #1756
With AUTH_SEND_JWT_HEADER=true, frontend now properly handles JWT authentication:
- Store JWT token in client-side cookie named 'JWT'
- Extract and store XSRF token from JWT payload
- Set Secure flag automatically when on HTTPS connection
- Update documentation to clarify this behavior
This fixes an issue where login state would be lost after page reload
when using header-based JWT authentication.
This commit replaces all references to `umputun/remark42` Docker images
on Docker Hub with `ghcr.io/umputun/remark42` from the GitHub
Container Registry. It updates various Docker Compose files,
documentation, and the Makefile to use the new image location.
It also updates the kubernetes example to use the latest version.
Docker Hub is going to kill free pulls for too long by now.
`format=tree` pagination provides top-level comments with all replies
and returns the last top-level comment as `last_comment` to be used
as `offset` for the next page. If comments and replies overflow
the limit, the one stepping out of the limit will not be returned.
If the first comment and its replies after the given offset overflow
the limit, it will be returned with all the replies.
`format=plain` pagination works by providing all comments and returning
the last comment as `last_comment` to be used as `offset`
for the next page.
This clarifies that the parameter sets CSP 'frame-ancestors'
to limit hosts allowed to embed comments. The commit also improves
the documentation on how to use ALLOWED_HOSTS with AUTH_SAME_SITE
for different setup scenarios.
We might want to change AUTH_SAME_SITE to `strong` in v2.0 as it works
on the subdomain of the same site as well as current Lax option.
Change the default img-src value to "*" and sets it to "'self'" when
image proxy is enabled. The previous state was inversion of this logic
which was wrong.
`Content-Security-Policy` now restricts resource loading and execution
to enhance security:
- `default-src 'none'`: Disallow all resource loading by default.
- `base-uri 'none'`: Prevents the use of `<base>` tag to change the
base URL for relative URLs.
- `form-action 'none'`: Disallows form submissions.
- `connect-src 'self'`: Restricts the origins that can be connected to
(via XHR, WebSockets, etc.) to the same origin.
- `frame-src 'self'`: Restricts the origins that can be embedded using
`<frame>` and `<iframe>` to the same origin (for `/web/` demo
endpoint).
- `frame-ancestors %s;`: Specifies the origins that are allowed to
embed this content in a frame. If no specific origins are allowed, it
defaults to `*` (any origin). This enhances security by controlling
which sites can embed your content.
- `img-src 'self'`: Allows images to be loaded only from the same
origin. If `imageProxyEnabled` is true, allows images from any origin
(`*`).
- `script-src 'self' 'unsafe-inline'`: Allows scripts to be loaded and
executed only from the same origin and allows inline scripts.
- `style-src 'self' 'unsafe-inline'`: Allows styles to be loaded and
applied only from the same origin and allows inline styles.
- `font-src data:`: Allows fonts to be loaded from data URIs.
- `object-src 'none'`: Disallows the use of `<object>`, `<embed>`, and
`<applet>` tags.
`Permissions-Policy` now restricts the use of certain browser features
which we don't use to enhance user privacy and security:
- `accelerometer=()`: Disables the use of the accelerometer sensor.
- `autoplay=()`: Disables automatic playback of media.
- `camera=()`: Disables the use of the camera.
- `cross-origin-isolated=()`: Disallows the page from being treated as
cross-origin isolated.
- `display-capture=()`: Disables the ability to capture the display.
- `encrypted-media=()`: Disables the use of Encrypted Media Extensions
.
- `fullscreen=()`: Disables the ability to use fullscreen mode.
- `geolocation=()`: Disables the use of geolocation.
- `gyroscope=()`: Disables the use of the gyroscope sensor.
- `keyboard-map=()`: Disables the use of the keyboard map.
- `magnetometer=()`: Disables the use of the magnetometer sensor.
- `microphone=()`: Disables the use of the microphone.
- `midi=()`: Disables the use of the MIDI API.
- `payment=()`: Disables the Payment Request API.
- `picture-in-picture=()`: Disables the use of Picture-in-Picture mode
.
- `publickey-credentials-get=()`: Disables the use of the Web
Authentication API.
- `screen-wake-lock=()`: Disables the ability to prevent the screen
from dimming.
- `sync-xhr=()`: Disables synchronous XMLHttpRequest.
- `usb=()`: Disables the use of the USB API.
- `xr-spatial-tracking=()`: Disables the use of spatial tracking in
WebXR.
- `clipboard-read=()`: Disables the ability to read from the clipboard
.
- `clipboard-write=()`: Disables the ability to write to the clipboard
.
- `gamepad=()`: Disables the use of the Gamepad API.
- `hid=()`: Disables the use of the Human Interface Device API.
- `idle-detection=()`: Disables the ability to detect idle state.
- `interest-cohort=()`: Disables the use of interest cohort tracking.
- `serial=()`: Disables the use of the Serial API.
- `unload=()`: Disables the ability to use the `beforeunload` and
`unload` events.
- `window-management=()`: Disables the ability to use window
management APIs.
The logout auth endpoint was returning no response body and type
application/json which is not valid, this commit changes it to return
plain/text instead which makes it valid.
MakeTree calculated Info locally for historical reasons,
and the results were consistent with the dataService.Info call
but calculated differently.
That change fixes that, ensuring that Info is requested
in the same manner.
Previously, the error printed was just the following:
error response "401 Unauthorized", Unauthorized"
New error:
error response "401 Unauthorized", ensure you have set ADMIN_PASSWD
and provided it to the command you're running: Unauthorized
Previously, status 200 was set for file export, which is used
for backup, which resulted in an inability to set an error status code
in case of a problem with file generation.
After this change, status code 200 would be written automatically by Go
before we start writing the response's body.
Previously, images were deleted only from comments deleted
before EditDuration expiration. After this change, any deletion
of the comment deletes images if they are not used elsewhere
in comments under the same page.
Previously, top-level comments were incorrectly assigned
parent comment id "root", which made them non-root,
so they are not returned when requested
in the `/find?format=tree` API call.
To fix the previously imported comments, please export all your comments
and replace `"pid":"root"` with `"pid":""` and then re-import them.
Previously, only the first one was returned for site-wide requests,
and now all returned information will be correctly aggregated,
and the PostInfo.URL and PostInfo.ReadOnly parameters will be dropped.
Allowed domains consist of `REMARK_URL` second-level domain (or whole IP in case it's IP like `127.0.0.1`) and `ALLOWED_HOSTS`. That is needed to prevent Remark42 from asking arbitrary servers and storing the page title as the comment.PostTitle.
Previous behaviour allowed the caller of the API to create a comment
with an arbitrary URL and learn the title of the page, which might be
accessible to the server Remark42 is installed on but not to the user
outside that network (CWE-918).

Previously, we stripped unsafe HTML tags but left some,
but it's not expected to have a link in a title or username,
so the new behaviour is stripping everything.
Previously, proxied and local images were checked for presence in the
storage before previewing or posting the comment. That logic resulted in
an inability to post with an image when a proxy for images is enabled,
as proxied images are not downloaded to disk before the first time
someone loads them, which could only happen after the user either
previews or posts the message.
After this change, preview and post only checks the local images'
presence and ignore the proxied ones.
1) Current implementation simply removes the last word, without truncating up to limit length.
2) In case if even the first word (magnet link or some base64?) is too long don't add extra space.
* Email subscription params in request body

When user logged in with the same email he tries to subscribe
* Skip confirm step on email sub
set autoConfirm param to make it work
* Update size-limit

prevStep is not used anywhere else and because of it influences output text (haveSubscribed), have changed it to more intuitive justSubscribed variable
* Test case for http error 409
(url) is a text inserted by default and never an intended URL.
That additional validation will ensure that users won't post relative
links because they are rarely intended.
Without this option, the aud is ignored.
It works only with RPC admin storage.
The shared key returned for all requests with the default shared admin
storage, so enabling that option does not affect it.
- replace undocumented `substr` with `substring`
- remove unused code
- inline a few variables
- simplify ifs when possible
- improve saveCollapsedComments documentation
- cleanup the unused imports
- remove unused variables and types
Previous behaviour is preserved for query parameters way of requesting
the subscription. The new behaviour with the possibility to confirm
the email right away without a separate /email/confirm call is enabled
only with request params sent in the request body, which was not a thing
before 27fc339e, which was merged just now and is not part
of any tagged version yet.
Previously it said just "Token", but now it will provide more explicit
instructions about copying and pasting the token received by email.
Resolves#1339
I haven't found a linter for these, so I had to catch these manually.
I found #757 to fix one of these, and I thought it would be good
to fix everything at once.
Previously, the cache kept the entry and deletion of the parent comment
after child deletion was not possible for the rest
of cache life (5m) duration. Now it's possible to delete
a parent comment after the deletion of the child comment
by a user or admin.
Resolves#1481
Previously, an image built for the `build` service was then used
for `server`, and changes were invisible to the user
before the container rebuild.
After that change, the useless static `build` service is deleted,
Dockerfile is only used in the CI pipeline, and only the `server`
service is left in docker-compose for the user to test
and see documentation changes locally in real-time.
Resolves#1178
Fixes the following conversion problem for BlockedUser:
```
panic: interface conversion: interface {} is map[string]interface {},
not store.BlockedUser [recovered]
```
Resolves#1475.
As discovered in #1477, dashes are expected to work in the site ID
and do work everywhere but in email auth. That change makes
the behaviour consistent: site ID now allows dashes.
After this commit, dev auth would start working with the `REMARK_URL`
hostname instead of the previously hardcoded 127.0.0.1.
Breaks development setup where `REMARK_URL` was set
to a non-standard value and dev auth was running on 127.0.0.1
and working, as, after that change, it would stop working.
Before that change, docker would create a new image
on docker-compose file changes.
Frontend docker-compose file change removes options set
to the same values as their default values.
Currently, such a build most likely has access to secrets but
fails due to the wrong username logging with DockerHub when
rebase is done by anyone but @umputun.
I've missed that last case in 5e5b3e0 and ad5d555.
Currently, such a build most likely has access to secrets but
fails due to the wrong username logging with DockerHub when
rebase is done by anyone but @umputun.
Currently, this step emits the
"Error: No PR found. Only pull_request workflows are supported."
message when run on the master branch commits (after the merge),
so the change prevents it from being run there.
Timeout, admin password and site id are set in many commands,
and we need to take care of synchronising the descriptions
and flags between them.
This change moves these standard options to cmd.go importing them
in the same manner CommonOpts imported by all commands already.
Few things here:
1. Merge automatic and manual backup to a single page
2. State that ADMIN_PASSWD must be enabled for backup or restore to work
3. Remove unneeded usage of --admin-passwd from commands
inside the container
4. Make the main backups page (not clickable through the interface,
available only in search) redirect to information about backups
instead of displaying text
5. Add HTTPS port to canonical docker-compose.yml
6. Clarify build option in the canonical docker-compose.yaml
Some time ago Gatsby started to support Typescript natively. Also the frontend of remark42 is written in Typescript. So I thought it's a good idea to add a Typescript version of the component.
Currently, such a build most likely has access to secrets but
fails due to the wrong username logging with DockerHub when
rebase is done by anyone but @umputun.
Previously it was sanitised using the HTML sanitiser,
but it had proven troublesome and unnecessary.
Remark42 rendered the markdown into proper HTML, but then some pieces
of it (like cited HTML code inside the code block, marked by backticks)
were cut out, which then showed the incorrect markdown to a user when
they were editing the comment.
For example, the comment "`foo<bar>`" became "foo" after sanitising,
and despite the proper render user saw only "foo" when editing
the comment.
After this change, the initial comment markdown is preserved unaltered.
It could contain dangerous HTML with JS, which I assume shouldn't
be a problem as it's never rendered as HTML but instead supposed
to be converted to HTML by the interpreter. In Remark42, it's stored
in a comment.Text field and sanitised and thus safe.
I've left information about the potential danger of rendering
the original markdown as-is without an interpreter in
all relevant places I could find.
Previously we built a Docker image just for the test,
but the introduction of multi-arch build in 9fbf0952
build also meant the push of the image, so it was
restricted only to the master branch.
This change re-introduces the Docker image build
outside the master branch, which is helpful
in pull requests.
We recently had a few frontend PRs which broke
the Docker image build silently, and that change
prevents it from happening.
In #1359, we discovered that StartTLS was not working\
due to the wrong host passed. This bumps the library for the fix.
Also, after a switch to go-pkgz/notify MailGun email sending
broke due to the difference in the destination email parsing,
the fix is also applied after this commit.
That option allows having backend-only build,
skipping the long frontend build and test step.
Frontend developers run NodeJS locally and usually
don't need to have frontend built inside the docker image.
We have plenty of paths used in the application, but two of them
are hardcoded in examples all over the code for historical reasons.
I found that by default in Docker, the path would resolve to the value
we are setting it explicitly to, so it doesn't make sense to set
a few variables we are setting now explicitly.
Telegram authentication requires you to open a chat on the phone.
It's convenient to have a QR code for the case when you want to
log in on the computer but have Telegram only on your phone
and would be able to scan the QR instead of copy-pasting the link
from the computer to the phone any other way.
Originally we thought of generating QR on the client but found
backend-generated QR a better alternative because we avoid adding
one more JavaScript dependency to the frontend that way.
For example, when notify.telegram.token and telegram.token
are both set but to different values, user might see
"access denied" error in log on attempt to send telegram
notification, thinking that notify.telegram.token value
is used, when in fact it is ignored and only telegram.token
is used.
New behavior is the same, ignoring the old param when new
one is set, but issuing the error log message which
explicitly tells the user about that.
Resolves#1218.
Remove generic development documentation, make frontend
and backend pages more specific and self-sufficient,
as previously you had to read development and frontend
pages in order to understand how to properly develop
frontend.

- compose everything inside fetchComments
- put skip counter in ref and prevent unnecessary rerenders
- got rid of additional handlers for loading
- add spinner as loading indicator for loading of additional comments
Previously it was done through writing bot first,
clicking a button, copying the token, and pasting
it into the web interface.
The new flow is way simpler: click the link
to write bot a message, then click the "Check"
button in the web UI and you got notifications
enabled.
Due to the wrong order of `html.UnescapeString`
applying, messages sometimes ended up crippled.
Due to `parse_mode=Markdown` set in Telegram
send message call, `ParseMode` in message
was ignored.
An HTTP header cannot be empty, and although some webservers allow this
(nginx, Apache), others answer 400 Bad Request (lighttpd), preventing
the widget from loading.

The current state is a mess of user and admin
notifications, which will become worse after
implementing the new user notification methods
like a telegram.
This change makes things simpler
for the remark42 users.
Before:
failed to make notify service,
failed to create email notification destination:
can't set templates:
can't read message template:
open email_reply.html.tmpl:
no such file or directory
After:
make notify, types=[email]
create notifier service, queue size=100, destinations=1
Also:
- make commitTTL equal to EditDuration,
so that image is committed to permanent
storage after comment can no longer be edited
- move cleanupTTL to Cleanup function,
as it's not used elsewhere in the code
- add variables to some tests sleeps, so that
instead of being magic numbers they would
rely on timers of structures they suppose
to wait for
This simplifies token and timeout reuse for
the notify module (used now) and for
the auth module later (not yet in the code).
SMTP credentials are already set up that way.
That function returns an error in a never
expected condition, and that error would be
logged message on the caller side:
none of the callers handles it.
That change hides that error from the caller
so that function would have a signature that
better fit what it does and how it behaves.
So that image is committed to permanent
storage after comment can no longer be edited.
Also, move cleanupTTL to Cleanup function,
as it's not used elsewhere in the code.

It was supposed to solve #253 but frontend part for it in

this code around is too high, we'll re-add it in case
frontend implementation will be finished.

- **Before committing**: Always run tests and linter on both main backend AND examples
- **Go module changes**:
- **Any** change to `backend/go.mod` or `backend/go.sum` requires `go mod tidy` in `backend/_example/memory_store` in the same commit. That covers dependency bumps, adding or removing a dependency, and changing the `go` directive, not only version updates.
- Only `go mod tidy` there, not `go mod vendor`: the example's vendor directory is gitignored (`.gitignore:26`), so its output is never committed, while a stale local copy silently becomes what the example resolves against.
- The example module replaces `github.com/umputun/remark42/backend` with `../../`, so it carries the backend's dependencies as indirect entries. Leaving them stale fails the `test examples` CI step with `go: updates to go.mod needed; to update it: go mod tidy`.
- This applies to Dependabot pull requests too: the bot updates `backend/` only, so its Go module PRs need the example tidied before they can go green.
## Backend Test Determinism
Backend tests must never depend on how fast the machine is. CI runs them under `-race` with coverage on a shared runner, so any test that assumes an operation finishes within some duration eventually fails on a rerun-and-it-passes basis.
- **Wait on a condition, never on a duration.** Use `require.Eventually` / `require.EventuallyWithT` to poll for the state the assertion needs, and `require.Never` when the point is that something did *not* happen. A bare `time.Sleep` before an assertion is a defect; sleeping until a deadline you computed, as `waitPastMillisecond` does, is not.
- **Polling closures must not touch `*testing.T`.** testify runs them on a separate goroutine, where `t.FailNow` is undefined behaviour. Assert on the `*assert.CollectT` that `EventuallyWithT` hands the closure, so the real error also lands in the failure message.
- **Mind the rate limiter when polling over HTTP.** Route groups are capped independently and most of the caps are hard-coded in `rest.go`, out of reach of a test: `/auth/` at 2 req/s and the admin, protected and image routes at 10 req/s. Only the open-route group is settable, via `openRouteLimiter` (100 in `startupT`). Poll with the existing constants rather than a new number, `httpPoll` for anything issuing an HTTP request and `pollInterval` only for in-process or filesystem checks, or the poll manufactures the 429s it then has to interpret.
- **When a test needs time to have passed, pin the clock input rather than waiting for it:** `os.Chtimes` for file ages, an explicit `store.Comment.Timestamp` for anything that formats a timestamp.
- **Prefer a `testing/synctest` bubble** where the code under test has no real I/O. Inside one the clock is fake, so `time.Sleep` is instant and deterministic. `app/notify`, `app/store/service`, `app/store/image`, `app/store/engine`, `app/providers`, `app/migrator` and `_example/memory_store/accessor` already use it, and most surviving `time.Sleep` calls live in them.
- **Helpers fail loudly.** A wait that gives up must call `t.Fatal`/`require` naming what it was waiting for, never return silently and leave the next assertion to fail with something unrelated. Because these packages run `goleak.VerifyTestMain`, a failing helper also exits the test goroutine, so anything that started a server in a goroutine must `defer cancel()` or `defer srv.Shutdown()` right after launching it; otherwise a failed readiness wait is reported as a goroutine leak rather than the failure that caused it.
- **Take ports and paths from outside the test.** Ports come from the kernel with `net.Listen("tcp", ":0")`, files from `t.TempDir()`. `go test ./...` runs package binaries concurrently, so a number out of a fixed range or a fixed name under `/tmp` lets two of them collide.
- **Close idle connections before shutting a test server down.** Clients built as `http.Client{Timeout: x}` share `http.DefaultTransport`, and `Shutdown` waits on their keep-alive connections until its own deadline expires.
- **Keep the test timeout budgets aligned.** `Makefile`, `ci-backend.yml`, `release.yml` and the command above all use `-timeout=300s`; the wait helpers allow 30s per condition, so a shorter per-package budget turns a slow runner into a timeout panic instead of a readable failure.
`chooseUnusedPort` and the server-start wait helpers are duplicated in `app`, `app/cmd`, `app/rest/api` and `_example/memory_store/server`. Nothing shares them today; keep the copies in step when changing one.
## Release Procedure
Remark42 uses two tags for each release:
-`vX.Y.Z` - product release tag used by GitHub releases, GoReleaser binary artifacts, and Docker image publishing.
-`backend/vX.Y.Z` - nested Go module tag for `github.com/umputun/remark42/backend`.
Release flow:
1. Create the GitHub release for `vX.Y.Z` with title `Version X.Y.Z`. The GitHub release must exist before the `vX.Y.Z` tag reaches the remote; `gh release create vX.Y.Z` satisfies this because it creates and pushes the tag.
2. The `vX.Y.Z` tag triggers GoReleaser, which builds and uploads binary artifacts to the existing release.
3. Create and push the matching backend module tag pointing at the same commit:
```bash
git fetch origin --tags
git tag backend/vX.Y.Z vX.Y.Z
git push origin backend/vX.Y.Z
```
GoReleaser must ignore `backend/*` tags in `.goreleaser.yml` so release notes and current-tag detection use only product tags. Docker image publishing stays separate and is handled by the existing Docker workflow.
For local artifact runs, install GoReleaser, Go 1.25, Node 24+ and PNPM 10, then use `make release`. The target runs a snapshot/no-publish GoReleaser build, leaves local artifacts and metadata in `dist/`, and cleans generated frontend embed files after GoReleaser exits. Do not run raw `goreleaser release` for local artifacts unless you also run `./scripts/cleanup-release-assets.sh` afterward.
## Milestones and Issue Labels
**Milestones** — one `vX.Y.Z` milestone per release. Assign every merged PR, and every issue closed by a code change, to the milestone of the release it shipped in.
- Decide which release a PR belongs to by whether its merge commit is **contained in a release tag** — not by comparing dates (a tag can be cut from an earlier commit, or moved). `git fetch --tags`, then `git tag --contains <merge_sha> | grep '^v' | sort -V | head -1` is its release. If no release tag contains it yet, it belongs to the next (unreleased) version's milestone — create it if missing (`gh api repos/umputun/remark42/milestones -f title="vX.Y.Z"`).
- An **issue gets a milestone only when it was closed by a code change** (a linked closing PR/commit); take the milestone from that PR/commit (via the commit-in-tag rule). Issues closed as `duplicate`/`invalid`/`wontfix`/answered get no milestone.
- Find unassigned: `gh pr list --state merged --search "no:milestone"`, `gh issue list --state closed --search "no:milestone"`. Assign with `gh pr edit N --milestone "vX.Y.Z"` / `gh issue edit N --milestone "vX.Y.Z"`.
**Issue labels** — classify each issue with a type and an area (add priority when relevant):
- Resolution (on close, when applicable): `duplicate`, `invalid`, `wontfix`, `no-action-needed`
- PR auto-labels (applied by Dependabot/Actions, not manual PRs): `dependencies`, `go`, `javascript`, `github_actions`
## Code Style
- **Backend**: Formatting with golangci-lint, strict error handling
- **Frontend**: TypeScript with ESLint, Stylelint and Prettier
- **Imports**: Group stdlib, external packages, then internal packages
- **CSS**: All components use CSS Modules (`component.module.css`). Class naming: BEM block = `.root`, elements = camelCase, modifiers = camelCase. Use `clsx` for conditional class composition. `raw-content.css` is the only global CSS file (syntax highlighting utility). Root wrapper keeps bare `.dark`/`.light` theme class — 8+ module CSS files depend on `:global(.dark)` ancestor. `comment_highlighting` uses `:global()` for imperative `classList` usage in root.tsx

```
#### Quick installation test
To verify if remark has been properly installed, check a demo page at `${REMARK_URL}/web` URL. Make sure to include `remark` site id to `${SITE}` list.
#### Register oauth2 providers
Authentication handled by external providers. You should setup oauth2 for all (or some) of them to allow users to make comments. It is not mandatory to have all of them, but at least one should be correctly configured.
##### Google Auth Provider
1. Create a new project: https://console.developers.google.com/project
1. Choose the new project from the top right project dropdown (only if another project is selected)
1. In the project Dashboard center pane, choose **"API Manager"**
1. In the left Nav pane, choose **"Credentials"**
1. In the center pane, choose **"OAuth consent screen"** tab. Fill in **"Product name shown to users"** and hit save.
1. In the center pane, choose **"Credentials"** tab.
* Open the **"New credentials"** drop down
* Choose **"OAuth client ID"**
* Choose **"Web application"**
* Application name is freeform, choose something appropriate
* Authorized origins is your domain ex: `https://remark42.mysite.com`
* Authorized redirect URIs is the location of oauth2/callback constructed as domain + `/auth/google/callback`, ex: `https://remark42.mysite.com/auth/google/callback`
* Choose **"Create"**
1. Take note of the **Client ID** and **Client Secret**
_instructions for google oauth2 setup borrowed from [oauth2_proxy](https://github.com/bitly/oauth2_proxy)_
##### GitHub Auth Provider
1. Create a new **"OAuth App"**: https://github.com/settings/developers
1. Fill **"Application Name"** and **"Homepage URL"** for your site
1. Under **"Authorization callback URL"** enter the correct url constructed as domain + `/auth/github/callback`. ie `https://remark42.mysite.com/auth/github/callback`
1. Take note of the **Client ID** and **Client Secret**
##### Facebook Auth Provider
1. From https://developers.facebook.com select **"My Apps"** / **"Add a new App"**
1. Set **"Display Name"** and **"Contact email"**
1. Choose **"Facebook Login"** and then **"Web"**
1. Set "Site URL" to your domain, ex: `https://remark42.mysite.com`
1. Under **"Facebook login"** / **"Settings"** fill "Valid OAuth redirect URIs" with your callback url constructed as domain + `/auth/facebook/callback`
1. Select **"App Review"** and turn public flag on. This step may ask you to provide a link to your privacy policy.
##### Yandex Auth Provider
1. Create a new **"OAuth App"**: https://oauth.yandex.com/client/new
1. Fill **"App name"** for your site
1. Under **Platforms** select **"Web services"** and enter **"Callback URI #1"** constructed as domain + `/auth/yandex/callback`. ie `https://remark42.mysite.com/auth/yandex/callback`
1. Select **Permissions**. You need following permissions only from the **"Yandex.Passport API"** section:
* Access to user avatar
* Access to username, first name and surname, gender
1. Fill out the rest of fields if needed
1. Take note of the **ID** and **Password**
For more details refer to [Yandex OAuth](https://tech.yandex.com/oauth/doc/dg/concepts/about-docpage/) and [Yandex.Passport](https://tech.yandex.com/passport/doc/dg/index-docpage/) API documentation.
##### Anonymous Auth Provider
Optionally, anonymous access can be turned on. In this case an extra `anonymous` provider will allow logins without any social login with any name satisfying 2 conditions:
- name should be at least 3 characters long
- name has to start from the letter and contains letters, numbers, underscores and spaces only.
#### Initial import from Disqus
1. Disqus provides an export of all comments on your site in a g-zipped file. This is found in your Moderation panel at Disqus Admin > Setup > Export. The export will be sent into a queue and then emailed to the address associated with your account once it's ready. Direct link to export will be something like `https://<siteud>.disqus.com/admin/discussions/export/`. See [importing-exporting](https://help.disqus.com/customer/portal/articles/1104797-importing-exporting) for more details.
2. Move this file to your remark42 host within `./var` and unzip, i.e. `gunzip <disqus-export-name>.xml.gz`.
3. Run import command - `docker exec -it remark42 import -p disqus -f {disqus-export-name}.xml -s {your site id}`
#### Initial import from WordPress
1. Install WordPress [plugin](https://wordpress.org/plugins/wp-exporter/) to export comments and follow it instructions. The plugin should produce a xml-based file with site content including comments.
2. Move this file to your remark42 host within `./var`
3. Run import command - `docker exec -it remark42 import -p wordpress -f {wordpress-export-name}.xml -s {your site id}`
#### Backup and restore
##### Automatic backups
Remark42 by default makes daily backup files under `${BACKUP_PATH}` (default `./var/backup`). Backups kept up to `${MAX_BACKUP_FILES}` (default 10). Each backup file contains exported and gzipped content, i.e., all comments. At any point, the user can restore such backup and revert all comments to the desirable state. Note: restore procedure cleans the current data store and replaces all comments with comments from the backup file.
For safety and security reasons restore functionality not exposed outside of your server by default. The recommended way to restore from the backup is to use provided `scripts/restore-backup.sh`. It can run inside the container:
You can use as many nodes like this as you need to.
The script will found all them by the class `remark__counter`,
and it will use `data-url` attribute to define the page with comments.
Also script can uses `url` property from `remark_config` object, or `window.location.href` if nothing else is defined.
## Build from the source
- to build docker container - `make docker`. This command will produce container `umputun/remark42`.
- to build a single binary for direct execution - `make OS=<linux|windows|darwin> ARCH=<amd64|386>`. This step will produce executable
`remark42` file with everything embedded.
## Development
You can use fully functional local version to develop and test both frontend & backend.
To bring it up run:
```bash
# if you mainly work on backend
docker-compose -f compose-dev-backend.yml build
docker-compose -f compose-dev-backend.yml up
# if you mainly work on frontend
docker-compose -f compose-dev-frontend.yml build
docker-compose -f compose-dev-frontend.yml up
```
It starts Remark42 on `127.0.0.1:8080` and adds local OAuth2 provider “Dev”.
To access UI demo page go to `127.0.0.1:8080/web`.
By default, you would be logged in as `dev_user` which defined as admin.
You can tweak any of [supported parameters](#Parameters) in corresponded yml file.
Backend docker compose config by default skips running frontend related tests.
Frontend docker compose config by default skips running backend related tests and sets `NODE_ENV=development` for frontend build.
### Backend development
In order to run backend locally (development mode, without docker) you have to have latest stable `go` toolchain [installed](https://golang.org/doc/install).
To run backend - `go run backend/app/main.go --dbg --secret=12345 --dev-passwd=password --site=remark --url=http://127.0.0.1:8080`
It stars backend service with embedded bolt store on port `8080` with basic auth, allowing to authenticate and run requests directly, like this:
Frontend guide can be found here: [./frontend/README.md](./frontend/README.md)
## API
### Authorization
* `GET /auth/{provider}/login?from=http://url&site=site_id&session=1` - perform "social" login with one of supported providers and redirect to `url`. Presence of `session` (any non-zero value) change the default cookie expiration and makes them session-only.

_all admin calls require auth and admin privilege_
## Privacy
* Remark42 is trying to be very sensitive to any private or semi-private information.
* Authentication requesting the minimal possible scope from authentication providers. All extra information returned by them dropped immediately and not stored in any form.
* Generally, remark42 keeps user id, username and avatar link only. None of these fields exposed directly - id and name hashed, avatar proxied.
* There is no tracking of any sort.
* Login mechanic uses JWT stored in a cookie (httpOnly, secured). The second cookie (XSRF_TOKEN) is a random id preventing CSRF.
* There is no cross-site login, i.e., user's behavior can't be analyzed across independent sites running remark42.
* There are no third-party analytic services involved.
* User can request all information remark42 knows about and export to gz file.
* Supported complete cleanup of all information related to user's activity.
* Cookie lifespan can be restricted to session-only.
* All potentially sensitive data stored by remark42 hashed and encrypted.
## Technical details
* Data stored in [boltdb](https://github.com/coreos/bbolt) (embedded key/value database) files under `STORE_BOLT_PATH`
* Each site stored in a separate boltbd file.
* In order to migrate/move remark42 to another host boltbd files as well as avatars directory `AVATAR_FS_PATH` should be transferred. Optionally, boltdb can be used to store avatars as well.
* Automatic backup process runs every 24h and exports all content in json-like format to `backup-remark-YYYYMMDD.gz`.
* Authentication implemented with [go-pkgz/auth](https://github.com/go-pkgz/auth) stored in a cookie. It uses HttpOnly, secure cookies.
* All heavy REST calls cached internally in LRU cache limited by `CACHE_MAX_ITEMS` and `CACHE_MAX_SIZE` with [go-pkgz/rest](https://github.com/go-pkgz/rest)
* User's activity throttled globally (up to 1000 simultaneous requests) and limited locally (per user, usually up to 10 req/sec)
* Request timeout set to 60sec
* Admin authentication (`--admin-password` set) allows to hit remark42 API without social login and with admin privileges. Adds basic-auth for username: `admin`, password: `${ADMIN_PASSWD}`.
* User can vote for the comment multiple times but only to change the vote. Double-voting not allowed.
* User can edit comments in 5 mins (configurable) window after creation.
* User ID hashed and prefixed by oauth provider name to avoid collisions and potential abuse.
* All avatars resized and cached locally to prevent rate limiters from oauth providers, part of [go-pkgz/auth](https://github.com/go-pkgz/auth) functionality.
* Images can be proxied (`IMG_PROXY=true`) to prevent mixed http/https.
* Docker build uses [publicly available](https://github.com/umputun/baseimage) base images.
* [A Helm chart for Remark42 on Kubernetes](https://github.com/groundhog2k/helm-charts/tree/master/charts/remark42)
