Follow-up review pass after the cache fixes turned up several bugs in
the same family — silent failures that look like success to the client,
plus content-correctness issues in the ZIP and per-file delivery paths.
- zipStream: stop calling archive.finalize() on upstream/parser errors.
That produced a valid-looking ZIP (200 OK, archive opens) silently
missing entries — same class as #694, but worse because the user has
no signal anything went wrong. Destroy the response on failure
instead so the client sees a connection drop.
- zipStream: apply per-repo image/pdf gates inside the entry handler.
The single-file /file/... endpoint refuses to serve those types
via AnonymizedFile.isFileSupported when image=false / pdf=false, but
the ZIP shipped them anyway — privacy-relevant for maintainers who
toggle image=false to suppress identifying screenshots. Threaded
contentOptions through both ZIP entry points (direct and streamer).
- GitHubUtils.getToken: validate the OAuth token-refresh response
before persisting. On a non-2xx response or a body without a string
token, we used to overwrite the stored token with `undefined`, which
then propagated as `Authorization: token undefined` to every API
call — 401 even on public repos, with the config.GITHUB_TOKEN
fallback unreachable because the field was no longer falsy.
- AnonymizedFile.send (streamer branch): forward Content-Type from the
upstream streamer response. got.stream(...).pipe(res) carries body
bytes only, so the parent response had no Content-Type and browsers
guessed (text rendered as download, etc.). Also resolve on
res.on("finish") in addition to "close" — keep-alive sockets stay
open long after the response is delivered, delaying countView().
- Repository.updateIfNeeded: persist a renamed source.repositoryName
even when the commit hasn't changed. Previously the new value lived
in memory only and was overwritten on the next reload, so the
rename detection ran every request.
- Repository.anonymize: stop materialising a dummy {path:"",name:""}
FileModel for empty repos. That row collided with the special case
in AnonymizedFile.getFileInfo and surfaced in unfiltered listings.
- streamer/route POST /: reject filePath segments containing ".." or
empty parts. Defence in depth — the parent server validates against
FileModel before calling, but the streamer joins filePath straight
into the storage path, so any future caller forwarding an
unvalidated path could traverse out of the repo root.
