fix(deploy): make auto_deploy.sh's failures impossible to hide - #124
Conversation
Every command in the script except the explicit `if ! cmd; then log ...; exit 1; fi` ones was unguarded under `set -euo pipefail` — a transient failure anywhere else (git fetch, git rev-parse, docker compose images -q) killed the script instantly with zero log output, since log() was only called at specific checkpoints. This is exactly what happened 2026-09-17: the last deploy.log line was a GHCR pull failure at 01:48 UTC, then 16+ hours and ~190 cron ticks passed with nothing logged at all — including ticks that had a real commit waiting to deploy — because whatever failed died before reaching its own log() call. Fix: `exec >> "$LOG_FILE" 2>&1` right after computing LOG_FILE routes every command's stdout/stderr into the log unconditionally, and an ERR trap logs the failing line + exit code for anything that still slips past an explicit check. Quiet-on-true-no-op behavior is unchanged. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_0164NJHTuZYetWhRoUVqPKbR

Keep Docker error output in the deployment log.
2>/dev/null overrides the global redirection at Line 33. If docker compose images -q fails, the ERR trap logs only the line number and exit code. It does not log the Docker failure reason. Remove this redirect so the deployment log contains the actionable diagnostic.

scripts/auto_deploy.sh(the Oracle VM's deploy-polling cron) went silent for 16+ hours on 2026-09-17 — last log line was a GHCR pull failure at 01:48 UTC, then ~190 cron ticks produced zero log output even though a real commit (PR fix(build-poller): stop treating action_required/cancelled as build failure #123) was waiting to deploy the whole time.if ! cmd; then log ...; exit 1; fiones was unguarded underset -euo pipefail. Any transient failure elsewhere (git fetch,git rev-parse,docker compose images -q) killed the script instantly before it reached alog()call, leaving no trace.exec >> "$LOG_FILE" 2>&1right after computingLOG_FILEroutes every command's stdout/stderr into the log unconditionally, plus anERRtrap that logs the failing line number and exit code for anything that still slips past an explicit check.
