Address all golangci-lint v2.10.1 (CI's version) findings:
* Add http.MaxBytesReader hard cap to ParseMultipartForm sites in
rest_private.savePictureCtrl (32MB) and api/migrator (256MB) — fixes
G120 by bounding total request body before form parsing.
* Suppress G70x in CLI subcommands cmd/{backup,cleanup,import,remap}.go:
all four issue HTTP requests against operator-supplied RemarkURL/CLI
flags, never user input. Each suppression carries a one-line reason.
* Suppress G122 in image fs_store cleanup walk: staging directory tree
is server-only, no untrusted symlinks land there.
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.
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.
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 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.
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.
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.
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 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.
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.
