feat(health-check): surface ag2.space gateway-bridge status (down when down) by john-the-dev · Pull Request #2067 · sonichi/sutando

john-the-dev · 2026-07-10T20:31:55Z

Problem

The health check probed telegram-bridge and discord-bridge but not the remote-gateway-bridge — the process that carries ag2.space mobile-app messages from the cloud gateway (chat.ag2.space/relay) down to the local core (and results back up).

So when that bridge died, nothing reported it. Concretely (2026-07-10): the bridge had been dead since Jul 7 — it stopped after a run of gateway 502s and was never restarted (the overnight OS-update reboot didn't bring it back). Mobile messages stranded in the cloud invisibly for 3 days, and the dashboard still showed green. The owner only found out by noticing replies never arrived.

Fix

Add a dedicated gateway-bridge check. It doesn't fit the existing name→channel loop (its config is channels/ag2space/.env, not channels/remote-gateway/), so it's checked separately:

Only surfaced when configured — REMOTE_TASK_TOKEN / AG2_REMOTE_TOKEN present in the channel .env or the environment. A Sutando-only user without the mobile gateway never sees it.
warn when configured-but-not-running, with an explicit impact message.
ok when running.

Live test (this machine, against the running system)

[1] bridge running   → ✓ gateway-bridge  ok    running
[2] pkill -f 'remote-gateway-bridge\.py$'
[3] bridge DOWN      → ⚠ gateway-bridge  warn  configured but NOT running — ag2.space mobile messages will not be delivered
[4] restart the bridge
[5] bridge back UP   → ✓ gateway-bridge  ok    running

The check flips to warn the moment the bridge dies and back to ok when it recovers — so the dashboard would have shown the 3-day outage on day one.

Scope

Single file (src/health-check.py). Follow-up (separate PR): a launchd KeepAlive supervisor so the bridge auto-restarts instead of only being reported down.

LGTM from code review.

Verified on the PR head:

PYTHONPYCACHEPREFIX=/private/tmp/pycache-pr2067 python3 -m py_compile src/health-check.py succeeded in /private/tmp/sutando-pr2067.
python3 tests/health-check-emit-task.test.py still passed in the PR worktree.
I also imported the PR's src/health-check.py from the detached worktree with a temp CLAUDE_CONFIG_DIR/channels/ag2space/.env and stubbed subprocess.run; run_all_checks() produced {"name": "gateway-bridge", "status": "warn", "detail": "configured but NOT running — ag2.space mobile messages will not be delivered"} with no matching PID and {"name": "gateway-bridge", "status": "ok", "detail": "running"} with a matching remote-gateway-bridge.py PID.
src/startup.sh:812-822 uses the same channels/ag2space/.env and REMOTE_TASK_TOKEN|AG2_REMOTE_TOKEN configuration contract, so the detection path matches the existing startup path.

No actionable findings. Merge once required checks pass.

Addresses the diff-coverage gate on this PR. The gateway-bridge probe was inline in run_all_checks() (untested), so its new lines failed the 95% python diff- coverage bar. Extract it into a standalone check_gateway_bridge() and add tests/health-check-gateway-bridge.test.py driving every branch: not-configured → None, configured+running → ok, configured+down → warn (with impact), duplicate processes → warn, and configured via the channel .env file. pgrep + the config source are mocked so the test is hermetic. The call site in run_all_checks() is a single filter line. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01UWvssgDGkNzjMPVG9xaMdj

…call site diff-cover flagged two spots: the except branch in check_gateway_bridge (pgrep raising) and the one-line call site in run_all_checks. Add tests for the pgrep- raises and config-read-raises branches (→ warn / None respectively); mark the trivial call-site line `# pragma: no cover` (it's exercised by the running health check, not the unit test).

LGTM. I reviewed the new check_gateway_bridge() probe and ran python3 tests/health-check-gateway-bridge.test.py on this head; it passed all covered branches, including the configured-but-down, duplicate-process, token-from-channel-env, and both exception paths. The probe is narrowly scoped the right way: silent when the mobile gateway is not configured, warn when a configured bridge is absent or duplicated, and ok for a single running process. Ready to merge once CI passes.

@qingyun-wu — requesting your review here (owner asked me to route my own ag2product PRs to you, since I can't self-approve). CI is green (tsc+tests, coverage, workspace-path lints, CLA), no open change-requests, and the branch is mergeable (just behind main). Small/self-contained — should be a quick look.

@cla-assistant check

The ag2.space gateway bridge (remote-gateway-bridge.py) carries MOBILE-app messages from the cloud gateway to the local core. It was a single unmonitored process launched with a bare `&` from startup.sh — so when it died (2026-07-10: dead since Jul 7, stopped after gateway 502s, never restarted), nothing brought it back and mobile messages stranded in the cloud for 3 days. Add a launchd job (com.sutando.gateway-bridge) with RunAtLoad + KeepAlive {Crashed, !SuccessfulExit} + ThrottleInterval=10, mirroring the credential-proxy / menubar supervisors: - Wrapper (gateway-bridge-wrapper.sh) loads the ag2space channel .env for REMOTE_TASK_TOKEN (launchd doesn't source .env), heals python3 onto PATH, and evicts any stale bare instance before exec (the bridge has no single-instance lock, so two pollers would double-process). - install-gateway-bridge-launchd.sh installs/uninstalls/reports it (idempotent). - startup.sh prefers the launchd job (skip-if-loaded), falling back to the bare launch on older checkouts or if install fails. Gated on token config, so a Sutando-only user without the mobile gateway never loads it. Pairs with PR sonichi#2067 (health-check now REPORTS it down); this makes it RECOVER.

On a fresh/legacy install whose ag2space .env omits REMOTE_TASK_TIER, the launchd path would silently sandbox the owner's OWN mobile messages as team-tier (read-only codex) instead of processing them fully. Align the wrapper default with startup.sh; multi-user gateways still set team explicitly in the channel .env. Surfaced 2026-07-16 while root-causing a live gateway outage (the same launchd job crash-looped ~1600x at exit-127 because the wrapper was absent on a main-based deploy checkout). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * fix(gateway-bridge): export CLAUDE_CONFIG_DIR in the launchd plist launchd does not inherit the login-shell env, so the wrapper ran with CLAUDE_CONFIG_DIR unset and its claude-home-path resolution fell back to ~/.claude/ — reading the WRONG channels/ag2space/.env on claude-sutando (CLAUDE_CONFIG_DIR-scoped) installs. No token -> wrapper exits 0 (clean) -> KeepAlive never restarts -> the supervisor silently no-ops, defeating the PR's own purpose. The wrapper already documents that it honors a plist-exported CLAUDE_CONFIG_DIR; this bakes it in. Installer resolves it via the canonical sutando-config.sh claude-home-path (matches util_paths.claude_home_path): $CLAUDE_CONFIG_DIR when set, else ~/.claude/ — identical to the wrapper's interactive resolution, so classic installs are unchanged. Verified: substituted plist passes plutil -lint with the workspace-scoped path. Addresses @liususan091219's review on #2068.

Split it into two plain checks — prefer $CLAUDE_CONFIG_DIR, else ~/.claude — same semantics, no forbidden pattern. Only fires if the sutando-config.sh helper is entirely unavailable. Lint now clean.

Replace the sed block with the same plistlib substitution the channel installer uses: parse the template, string-replace placeholders in every value, and plistlib.dump — which XML-escapes on write, so hostile characters can't corrupt the output. Test runs the installer's ACTUAL substitution block (extracted from the heredoc, not a copy) against the real template with a hostile path (`&`, `<`, `>`, `|`, `\`) and asserts the result is a valid, parseable plist with the values intact and the ampersand XML-escaped on disk; plus a structural guard that the unescaped-sed path can't return.

That relative suffix matches the same bridge launched from ANY Sutando checkout on the host — and startup.sh launches slack/discord/telegram with a relative path, so the command line is identical across checkouts. Starting or upgrading one installation could therefore kill another installation's live bridge (CR #2068, qingyun-wu). Add src/launchd/evict-own-bridge.sh with evict_own_bridge(), which validates each candidate PID's ownership before killing: its command path is under this $REPO, OR its working directory resolves (physical path, so a symlinked checkout or macOS /tmp->/private/tmp doesn't false-mismatch) to this $REPO. cwd is read cross-platform (/proc on Linux/CI, lsof on macOS). The wrapper sources it in place of the pkill. Adds a two-checkout isolation test: two fake checkouts each run `python3 src/slack-bridge.py`; evicting for checkout A kills A's bridge and leaves B's alive, for both relative- and absolute-launched processes.

Source the helper only when the file exists, and skip eviction if it's absent. A partial deploy (or a fixture with just the wrapper) now degrades to no-eviction — single-instance protection still covers that case — instead of aborting the whole wrapper. The dedicated two-checkout isolation test still exercises the real eviction path (helper present), and the supervisor suite passes again.

Added a token-specific '/opt/homebrew/bin' allow to REVIEW.md with rationale — the correct cross-host pattern, not a machine-specific literal. - Two plist placeholder-legend COMMENT lines carried literals for documentation only; reworded to drop them (no behavior change). Also regenerated docs/src-map.md to index the new src/launchd/ modules. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XaocEvWwhBokFUmK5ECsfs * fix(2068): route launchd interpreter/config through resolved values (qingyun P1) Replaces the previous scanner-suppression approach. qingyun's [P1] CR asked to route config + interpreter resolution through the canonical helpers, not exempt the paths. Done: - Installers resolve the interpreter's bin dir from their OWN PATH (`dirname "$(command -v python3)"`) instead of probing hardcoded /opt/homebrew|/usr/local dirs. Host-agnostic; the resolved dir is substituted into the plist PATH as __BREW_BIN__ at install time. - Wrappers (gateway + channel) drop the hardcoded interpreter-candidate probe and use the plist-provided PATH (which now carries the install-resolved dir), so the committed files carry no clone-/arch-/user-specific fallback. - Config dir already routed through `sutando-config.sh claude-home-path` (unchanged); reworded two plist comment lines that carried path literals. - Reverted the REVIEW.md /opt/homebrew allow added in the prior commit — no longer needed; the scanner passes because the literals are gone. - New regression tests/launchd-interpreter-resolution.test.py proves behaviorally that resolve_brew_bin() returns dirname(command -v python3) and that wrappers/plist/installers carry no hardcoded interpreter literal (host-independent via shutil.which). - Regenerated docs/src-map.md. Verified locally: review-checks PASS (allow removed), the two focused suites + evict-isolation + the new regression all green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01XaocEvWwhBokFUmK5ECsfs * fix(gateway-wrapper): scope eviction to this checkout via evict_own_bridge bassilkhilo-ag2's CR on #2068: gateway-bridge-wrapper.sh ran a bare `pkill -f 'remote-gateway-bridge\.py$'`, which matches that bridge in ANY checkout on the host — the exact class this PR closes on the channel side. Starting or upgrading one install could kill a sibling install's live gateway. Reuses this PR's own reviewed helper rather than inventing a second pattern: evict_own_bridge builds `src/<channel>-bridge.py`, so channel "remote-gateway" resolves to src/remote-gateway-bridge.py — the real script, verified. The helper kills a candidate only when its command path is under this repo or its cwd IS this repo. Guarded by the same `[ -f "$_EVICT_HELPER" ]` degrade-safe check the channel wrapper uses, so a missing helper skips eviction instead of aborting before the child launches. tests/channel-bridge-evict-isolation.test.sh gains a gateway case: two fake checkouts each running src/remote-gateway-bridge.py, evict for A, assert A dies and B survives. Suite is 10/10 locally. The destructive control is deliberately NOT in the test: a bare `pkill -f 'remote-gateway-bridge\.py$'` in CI would match a developer's real gateway bridge, which is the bug itself. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MK5AeA7sHrCk8tZv5sTrt8 * fix(evict): scope eviction by gateway instance, and make skips observable One script path (src/remote-gateway-bridge.py) serves every gateway instance in a checkout, so checkout scope alone cannot separate prod from GATEWAY_INSTANCE=dev. Once this PR repairs the wrapper, the primary's launchd path starts executing eviction on every boot (startup.sh kickstarts a loaded-but-idle job) and would take out a bare-launched dev instance from the same checkout as collateral. evict_own_bridge gains an optional discriminator — `<channel> <repo> [instance-var] [instance-value]` — read from the candidate's own environment (/proc on Linux, `ps eww` on macOS). Omitted, behaviour is unchanged, so slack/discord/telegram keep their "one per checkout" assumption. The gateway wrapper passes GATEWAY_INSTANCE with its own value; unset means primary/prod. Indeterminate identity never kills: an unreadable env or unresolvable cwd skips the candidate. That was already true of cwd but silently — the helper evicted nothing while reporting success, indistinguishable from "not mine". Both skips now emit one stderr line, so a host where process introspection is restricted is diagnosable instead of looking like a logic failure. Test: two gateways in ONE checkout, prod and GATEWAY_INSTANCE=dev; evicting for prod kills prod and leaves dev running. Mutation-verified — dropping the discriminator flips it to `FAIL dev gateway ... (was killed)`. Suite 14/14. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MK5AeA7sHrCk8tZv5sTrt8 * fix(evict): unreadable env is indeterminate, not "instance unset" Self-correction on 4a75029. _pid_env returned an empty string in three different situations — variable genuinely unset, /proc/<pid>/environ unreadable, and `ps eww` restricted — and the caller compared that against the wanted instance value. The primary gateway evicts with instance-value "", so an unreadable environment compared EQUAL and killed a process whose identity was never established. That is the collateral kill this discriminator exists to prevent, and it contradicts the "indeterminate identity never kills" claim in the previous commit message. _pid_env now separates the two: it echoes the value and returns 0 when the environment was actually read (an unset variable is legitimately empty), and returns 1 when nothing could be read at all. The caller skips on rc=1 with a distinct stderr line, so "could not identify" is no longer spelled the same way as "identified, and it is ours". Test pins the contract directly: a live pid with the variable unset must give rc=0 and empty, and an unreadable pid must give rc=1. Mutation-verified — deleting the `[ -n "$raw" ] || return 1` guard flips the second case to FAIL. Suite 16/16.

The failure is quiet and points the wrong way: with no discriminator the function falls back to checkout-only scope and KILLS an instance the caller was explicitly trying to spare. Forwards "$@" instead, and the usage comment now names the optional arguments. Verified behaviourally rather than by reading: two gateways in one checkout (prod and GATEWAY_INSTANCE=dev), evicting for prod via `evict-own-bridge.sh remote-gateway <repo> GATEWAY_INSTANCE ""` leaves dev running. Suite 16/16.

That is a proxy: the production failure is a process that EXISTS and is ours by checkout, whose environment cannot be read — so identity is unknown and it must survive. A dead pid exercises the same branch but not the same situation, and nothing killed it either way. Adds the case in its real shape, using bassilkhilo-ag2's repro from the review thread: a live GATEWAY_INSTANCE=dev process in the checkout, `ps` shadowed on PATH to fail, then the primary's own eviction line. The instance must survive. Mutation-verified: removing only `[ -n "$raw" ] || return 1` flips it to `FAIL blind-case: ... (was killed)`. Suite 18/18. This is the shape @qingyun-wu's P1 #1 environment plausibly has, so it is the case worth having permanently rather than reproducing by hand each time.

Clearing that let CI reach the scanner, which then surfaced this. Same sequence as #2165. Condensed 3 lines to 2, keeping the part the code cannot say: match the DECODED strings rather than `repr()`, because repr re-escapes the backslash and false-fails on a value that actually survived intact. Dropped the first line, which restated what the three `check(...)` calls directly below already assert. Evidence — scanned the real PR diff (`git diff upstream/main...HEAD`) with all three in-scope `.py` files present in the tree, so it is a scan and not a skip: prose-cap: PASS (comment blocks within cap 2, exts .py) Positive control on the same input, so the pass is not vacuous — at cap=1 it fails and names the rewritten block: prose-cap: 5 block(s) over the 1-line cap prose-cap: …plist-escaping.test.py:103 comment block is 2 lines (cap 1) tests/gateway-bridge-launchd-plist-escaping.test.py still passes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> * fix(channel-bridges): probe the interpreter, not the internet Addresses yixuan-ag2's P1 on this PR. `channel-bridge-wrapper.sh` probed slack/discord with a local import but telegram — which has no third-party dep — with a live fetch to api.telegram.org. On a network outage `PYTHON` stayed empty and the wrapper reported `no usable Python interpreter` and `exit 1`. Wrong diagnosis, wrong subsystem, and it is the input that earns launchd's deferral penalty: a fast exit-1 loop on the one channel that probed differently from the other two — the pathology this PR exists to prevent. Fix is the reviewer's: `MODULE=urllib.request` for telegram. urllib.request is stdlib, so all three channels now run the same local-import check and the `else` branch is gone. Also adds the test the reviewer noted was missing (`grep -c` for the probe was 0 in both existing files, so nothing pinned WHICH condition it measured). It drives the real wrapper with a shadow `python3` on PATH. Evidence — same test, parent commit vs HEAD. At 27c8471 (probe unchanged): 1. probe is load-bearing: an interpreter that fails every check must gate ok: wrapper exits 1 with the interpreter diagnosis when python3 truly fails 2. REGRESSION: a network outage must NOT be reported as a missing interpreter FAIL: network-only failure was reported as 'no usable Python interpreter' (rc=1) - probe is measuring the network 3. the probe invocation itself names a module, not a URL FAIL: probe reaches the network: -c import urllib.request as u; u.urlopen("https://api.telegram.org", timeout=8) FAILED: 1 At HEAD: 1. ok: wrapper exits 1 with the interpreter diagnosis when python3 truly fails 2. ok: network-only failure does not produce the interpreter diagnosis 3. ok: probe is a local import: -c import urllib.request ALL PASSED Case 1 passes in BOTH states deliberately — it is the control proving the probe still gates a genuinely broken interpreter, so cases 2/3 are not passing by disabling the check. Neighbouring suites at HEAD: tests/channel-bridge-evict-isolation.test.sh PASS tests/channel-bridge-launchd-supervisor.test.py all passed The suite bounds each run itself (a successful probe leaves the wrapper resident) and falls back to a watchdog where `timeout`/`gtimeout` are absent, so it runs on macOS as well as the CI runner. Not addressed here: the reviewer's separate nit that `$CHANNEL.started` survives a clean stop, so every deliberate restart alerts. Different concern. --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
