Summary

  • Adds WriteComicInfoToCBZ in internal/comic/write.go — atomic temp+rename, NETWORK disk guard, CBZ-only guard, 100% test coverage via injectable OS + zip-entry deps (rebuildCBZWith, writeZipWith).
  • ExportComicInfo service maps book+comic metadata → BookLevelFields + DisplayMetadata and writes the sidecar; curried deps, ErrNotComic sentinel.
  • ExportComicInfoHandler thin HTTP wrapper: ErrNetworkDisk → 409, ErrNotCBZ → 400, JSON 200 {"ok":true} / browser 303 redirect with ?comicinfo_exported=1.
  • Route POST /books/{id}/export-comicinfo gated by g.EditMetadata.
  • books_show.html kebab menu gains "Export ComicInfo.xml" item for comic book types; book-detail-kebab Stimulus controller gains exportComicInfo(event) with fetch POST, toast success/error feedback, and a 409-specific message for NETWORK disk.

Test plan

  • make test — all unit tests pass
  • make coverage — 100% coverage, zero uncovered statement blocks
  • golangci-lint run ./internal/comic/... ./internal/books/... — 0 issues
  • Comic book: kebab menu shows "Export ComicInfo.xml"; non-comic books show nothing
  • POST /books/{id}/export-comicinfo returns 200 JSON {"ok":true} for a valid CBZ
  • Returns 409 when DISK_TYPE=NETWORK
  • Returns 400 when archive is RAR/CBR (not CBZ)
  • Returns 404 when book has no CBZ file

Closes bead bookshelf-w1or on merge.

The previous read-only-directory test (chmod 0o555 + expect CreateTemp to
fail) passes locally as a non-root user but FAILS in the CI container,
which runs as root — root bypasses directory permission bits, so
os.CreateTemp succeeds and the expected error never occurs.

Inject createTemp into rebuildCBZWith (alongside the existing closeFile
and rename injection points) and replace the permission-based test with a
deterministic stub that returns an error directly. No filesystem
permissions involved; behaves identically as root or non-root.

The export-comicinfo and step-edit handlers were swapped: wire.go passes
ExportComicInfoHandler then StepEditHandler, but RegisterRoutes declared
the stepEdit parameter first. As a result POST /books/{id}/export-comicinfo
was served by the step-edit handler and returned 400 "ids query parameter
is required". Reorder the RegisterRoutes parameters (exportComicInfo,
stepEdit) to match the wiring call order; the two stub handlers in
routes_test.go are identical 200s so the swap is behaviorally inert there
(comments updated to stay accurate).

Add coverage that would have caught this:
- Browser e2e Journey 6e (Ordered): seeds a CBZ + comic_metadata, opens the
  book-detail kebab, asserts the Export ComicInfo.xml item renders, clicks it,
  asserts the success toast, and asserts the on-disk ComicInfo.xml was
  rewritten with the DB Series. Requires real Chromium (Stimulus + real fetch
  with the page CSRF token + cross-controller toast + archive rewrite) — not
  reproducible in jsdom or the API e2e tier. Posts a kebab screenshot to the PR.
- Vitest: full branch coverage of the exportComicInfo controller method
  (POST URL, success toast, menu close, 409 NETWORK-disk message, non-409
  server error, missing-error-field fallback, non-JSON body, network failure,
  empty-URL guard, AppDialog-absent alert fallback).

Security Review — PR #634 (bookshelf-w1or) — ComicInfo.xml Export

Reviewed: internal/comic/write.go, internal/books/export_comicinfo_service.go, internal/books/export_comicinfo_handler.go, internal/books/routes.go, static/js/controllers/book_detail_kebab_controller.js, templates/pages/books_show.html, diff via API.

[MAJOR] internal/books/export_comicinfo_service.go:75 — archive path constructed without library-root traversal guard

archivePath := filepath.Join(libPath, cbzRow.FileSubPath) is passed directly to WriteComicInfoToCBZ without the strings.HasPrefix(filepath.Clean(archivePath), cleanedRoot+sep) guard that every other destructive file operation in this codebase applies explicitly.

delete_service.go:70-76 comments: "Security: verify the resolved path is contained within the library root" and skips any path that escapes. reader_service.go:357-359 and reader_handler.go:611-614 both apply the same guard before opening a file. attach_service.go:121-123 and move_service.go:465-472 also do it.

file_sub_path is written by the library scanner and is not user-controlled in the normal flow, so this is not immediately exploitable. However: (a) the convention in this codebase is explicit and documented; (b) a future code path that rewrites file_sub_path through a less-trusted channel would silently skip the guard here; (c) the archive is overwritten, not just read, making the blast radius of a traversal materially worse than the read paths.

Fix: Add before calling WriteComicInfo:

cleanedRoot := filepath.Clean(libPath) + string(filepath.Separator)
if !strings.HasPrefix(filepath.Clean(archivePath)+string(filepath.Separator), cleanedRoot) {
    return fmt.Errorf("export comicinfo: path escapes library root: %w", middleware.ErrNotFound)
}

[MINOR] internal/comic/write.go:23 — MaxWriteArchiveBytes comment says "buffer in memory" but writes stream to disk

The var comment reads "caps how large an archive we will fully buffer in memory". This is incorrect. io.Copy streams from the source zip entry to zip.Writer which writes through to the *os.File temp file — no in-memory accumulation. The guard correctly limits per-entry uncompressed size to protect against zip-bomb expansion during the copy (a legitimate and necessary check), but the stated reason is wrong and will mislead future maintainers about the actual memory profile.

Fix: Change the comment to: "caps the uncompressed size of any single entry copied during archive rebuild, guarding against zip-bomb expansion."

[MINOR] internal/books/export_comicinfo_handler.go:24 vs :80 — doc comment says 204, code returns 200

The handler doc comment says "JSON clients (Accept: application/json): 204 No Content" but the implementation calls w.WriteHeader(http.StatusOK) (200) and writes a JSON body {"ok":true}. The handler test asserts 200. Either the comment should say 200, or the implementation should be changed to 204 (omit body, use http.StatusNoContent). As-is the doc is wrong and the JS client checks resp.ok (which passes for any 2xx), so there is no functional breakage — but it will confuse future readers.

Fix: Align: either update the doc comment to say "200 OK with {\"ok\":true}" or change the implementation to w.WriteHeader(http.StatusNoContent) and drop the JSON body.

Items reviewed and found clean

  • Per-user library-access auth: checkBookAccess(ctx, bookID, userID) is called in the handler before export() is invoked. The wiring in wire.go:783-802 passes the same checkBookAccess used across all other mutation paths. The route registration at routes.go:116 gates the handler behind g.EditMetadata (PermissionEditMetadata). The access check returns middleware.ErrNotFound on miss (no library-ID leak). Correct.

  • CSRF: middleware.CSRF is applied globally in app.go:583 to the entire handler chain. The JS exportComicInfo() method sends X-CSRF-Token: csrfToken() (double-submit cookie pattern) on every fetch. Covered.

  • DISK_TYPE guard: WriteComicInfoToCBZ checks strings.ToUpper(diskType) == "NETWORK" (case-insensitive, tested) and returns ErrNetworkDisk before touching the filesystem. Handler maps this to HTTP 409. Correct.

  • Atomic write: temp file created in same directory as archive → writeZip → closeFile → os.Rename. Temp is cleaned up on writeErr, closeErr, or rename failure. Original archive is only replaced on a successful rename. Correct POSIX atomic pattern.

  • ZIP handling / zip-slip on write: writeZipWith copies entry FileHeader values verbatim (preserving names/paths). This is a write path — the entry names are written into the new temp archive, not extracted to disk. No zip-slip risk exists on the write side. Entry names from the existing archive in the library are server-trusted.

  • Zip-bomb / entry size cap: MaxWriteArchiveBytes (200 MB) is checked against f.UncompressedSize64 per entry before io.Copy. Entries exceeding the cap abort the rebuild with an error.

  • XML generation / injection: xml.NewEncoder with a struct of string-typed fields automatically escapes <, >, &, " — no raw injection risk. xml.Header prefix is correct.

  • Error propagation in zip.Writer: CreateHeader, fw.Write, and io.Copy errors are suppressed with //nolint:errcheck because zip.Writer records the first write error internally and surfaces it at zw.Close(), which is the correctly-checked return value. This is the idiomatic Go pattern for zip.Writer and is sound here.

  • No user-supplied path: archivePath is constructed entirely from DB-sourced values (libPath from GetLibraryPath, FileSubPath from GetPrimaryCBZFile), neither of which originates from the HTTP request.

  • Permission gate comment accuracy: Comment on ExportComicInfoHandler correctly documents g.EditMetadata as the gate (set at the mux level).

CODE REVIEW: NOT APPROVED

Phase 0: DEMO Verification

No DEMO block found in the PR body or bead comments. The PR has a test-plan checklist but no executable shell commands for me to re-run. Per review policy this is NOT APPROVED — "No DEMO block provided."

I continued through phases 1 and 2 to give actionable feedback regardless.

Phase 1 + 2: Findings

[MAJOR] internal/books/export_comicinfo_service.go:21 — struct-of-funcs banned by project conventions
ExportComicInfoDeps is an explicit struct-of-funcs, which project-conventions.md bans: "No struct-of-funcs shortcut, no interface escape hatch. If a function ends up needing five func args, that's a signal to split it; if it genuinely needs them, write the signature out." The service has 5 dep-funcs + 1 string field; write ExportComicInfo(getPrimaryCBZFile, getLibraryPath, getComicMetadata, getBookMetadata func(...) ..., writeComicInfo func(...) ..., diskType string) func(...) as individual curried arguments.

[MAJOR] internal/books/export_comicinfo_service.go:50-54 + export_comicinfo_handler.go:66 — CBR/RAR case yields 500, not 400
When a book's primary CBX file has archive_type = 'RAR' (i.e. CBR), the service returns ErrNotComic (line 54) — not comic.ErrNotCBZ. The handler only checks errors.Is(err, comic.ErrNotCBZ) (line 66) to map to 400; ErrNotComic falls through to the generic return err path, which the middleware translates to 500. The PR description and test plan both claim "returns 400 when archive is RAR/CBR" but this is incorrect. The handler test for "ErrNotCBZ → 400" (line 157) tests a case that cannot arise from the real service. Fix: add errors.Is(err, books.ErrNotComic) to the handler's error-mapping block and map it to middleware.ErrValidation, or have the service wrap with comic.ErrNotCBZ for the non-ZIP archive_type case.

[MINOR] internal/comic/write.go:79 — Volume XML field never populated despite DisplayMetadata.VolumeNumber existing
comicInfoXMLWrite.Volume is declared (line 79) and the <Volume> element in ComicInfo.xml represents the numeric volume identifier. DisplayMetadata has VolumeNumber *int32 (comic.go:43) but marshalComicInfo never sets info.Volume. A round-trip export will silently drop the volume number. Note: VolumeName correctly maps to <Series> (per the ComicInfo spec); the missing field is VolumeNumber → <Volume>. Add: if m.VolumeNumber != nil { info.Volume = fmt.Sprintf("%d", *m.VolumeNumber) }.

[MINOR] internal/books/wire.go:783-795 — misindented ExportComicInfoHandler block
The ExportComicInfoHandler(...) invocation and its ExportComicInfo(ExportComicInfoDeps{...}) inner call are indented incorrectly relative to the surrounding RegisterRoutes argument list. The args to ExportComicInfoHandler start at column 2 instead of matching the tab depth of sibling arguments. Minor cosmetic but noticeable against the rest of the file.

[MINOR] internal/books/export_comicinfo_handler.go:85-88 — JSON success response is 200 with body, doc comment says 204
The handler doc comment (line 26) says "204 No Content" for JSON clients but the code writes http.StatusOK (200) with {"ok":true}. Either fix the code to use 204 (and remove the body) or fix the comment. Minor inconsistency.

Summary

REVIEW VERDICT: 0 blocker, 2 major, 3 minor

The RAR→500 bug (major #2) is a real user-facing defect: a CBR comic triggers a 500 instead of a clear 400 "not writable" error. The struct-of-funcs (major #1) is a convention violation. Both need to be fixed before merge.

- Map ErrNotComic -> 400 Bad Request in handler; add handler test for RAR path

MINORs:
- Fix misleading MaxWriteArchiveBytes comment (streams, does not buffer)
- Populate Volume XML field from m.VolumeNumber in marshalComicInfo; add
  VolumeNumber field to DisplayMetadata + service.Get; add write_test +
