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 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.
* move email unsubscription page outside of API and make it HTML
* make separate HTML template for SendErrorHTML
* fix error template name
* add test for SendErrorHTML, introduce MustExecute function
* fix content check in test of TestSendErrorHTML
* fix logging test to be more generic and not depend on line numbers
- Adds common function to get error message from the http response
- Adds error message for the voting displayed under the voting buttons
