Reject path traversal in deploy log download handler (closes #177)
gosec flagged G703 (path traversal via taint analysis) on the log
download handler because the served path derives from a URL parameter.
Open the log file through an os.Root confined to the deploy log
directory instead of passing the path to http.ServeFile; Root.Open
rejects any path that escapes the root, so traversal attempts return
404. Serve the opened file with http.ServeContent. Adds GetLogDir on
the deploy service.

The traversal regression test plants a sentinel file at the location a
traversal-shaped app name resolves to (outside the log directory) and
asserts the handler returns 404 without leaking the sentinel, so it
fails if the os.Root guard is removed. Keeps the legitimate-download
test.

# Status
1.0+. Tagged 1.0.0 on 2026-02-26; 8 commits on main since. `make check`
is green as of the golangci-lint v2.12.2 update.
# Next Step
Confirm `.gitea/workflows/check.yml` gates merges on `make check` so
main cannot regress.
# Completed Steps
- 2026-09-22: Added `.prettierignore` so `make fmt` no longer rewrites
the vendored `static/js/alpine.min.js` bundle (#185).
- 2026-09-22: Fixed the gosec G703 path-traversal finding in the deploy
log download handler by verifying the resolved path stays within the
deploy log directory before serving, returning 404 on escape (#177).
- 2026-09-09: Fixed four deployability blockers found by QA: CSRF origin
check over plain HTTP (`UPAAS_PLAINTEXT_HTTP`, #189), pulling the git
image when absent (#190), the env-var editor CSRF token lookup (#191),
and the port-mapping delete form's CSRF field (#192).
- 2026-08-07: Updated golangci-lint to v2.12.2 (canonical
`.golangci.yml`, `Dockerfile` lint stage pin, `script/bootstrap`
release-archive pins) and fixed all resulting lint findings (noctx,
gosec, goconst, lll, dupl, nolintlint); `make check` green.
- 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints,
Makefile shims, README Entrypoints section
- 2026-03-11: Monolithic env var editing with bulk save (#158).
- 2026-03-10: Webhook event history UI page (#164); added missing
Makefile docker and hooks targets plus test timeout (#159);
notification settings passed from create form (#160).
- 2026-03-03: REPO_POLICIES compliance file set added (#155).
- 2026-03-01: Module path changed to sneak.berlin/go/upaas (#143);
Dockerfile split into lint and build stages with forced lint
execution (#152, #154).
- 2026-02-26: 1.0.0 tagged; dashboard CSRFField crash fixed (#146).
- 1.0 audit bug fixes (#120-#125): deferred rollback on commit error,
deployment log size cap, error path rendering, docker-compose bind
mount, domain type refactor.
- CI simplified to docker build only (#130).
- 2025-12-29 onward: core PaaS built out: deploys with real-time build
log streaming, container start/stop/restart and logs, TCP/UDP port
mapping, Alpine.js UI, Slack notifications, ULID app IDs, session
handling.
# Future Steps
- Resume feature work only after main is green.
