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.
* 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.

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.
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.
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, 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.
