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.
