From c47f52d78f04d47ed9680b132075a8a084bfa91c Mon Sep 17 00:00:00 2001 From: Shawn Xie Date: Wed, 10 Jun 2026 06:52:04 +0000 Subject: [PATCH 1/7] fix(sandbox): tie gateway healthcheck marker to launch site, not env hint (#4710) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The early conditional gating mark_in_container_gateway on OPENSHELL_DRIVERS=docker (PR #4748) never fires inside the sandbox container because OpenShell 0.0.44 does not export OPENSHELL_DRIVERS into the sandbox env. hulynn's 2026-06-08 re-verification on v0.0.60 confirmed the symptom is unchanged from v0.0.57: marker file is created on every NEMOCLAW_CMD-empty container, so the Dockerfile HEALTHCHECK short-circuit (`[ -f /tmp/nemoclaw-gateway-local ] || exit 0`) is unreachable for docker-driver sandboxes and the container is marked (unhealthy) on every fresh onboard. Fix: drop the early env-gated marker write and call mark_in_container_gateway() directly before each `openclaw gateway run --port ...` launch (both the non-root and root-mode paths). The marker is now true-by-construction: it exists if-and-only-if this container is about to start the gateway, regardless of how the deployment-mode signal is (or isn't) plumbed through the sandbox env. Restart-loop fallback launches inherit the marker from the first launch — the function is idempotent (`: >file`) so calling it again on retry is a no-op. Verified by two new regression tests in test/nemoclaw-start.test.ts: - 'ties the in-container gateway healthcheck marker to the gateway launch site (#4503, #4710)': asserts (a) the region immediately after the function definition contains no early call and no OPENSHELL_DRIVERS conditional, and (b) every `openclaw gateway run --port` invocation is preceded by mark_in_container_gateway within 6 lines (or sits inside a restart-loop body). - 'mark_in_container_gateway writes the marker file idempotently (#4710)': behavioral check on the helper itself. The two existing launch-block tests now stub `mark_in_container_gateway() { :; }` in their preamble to keep the extracted shell snippet self-contained. Test count: 120 passing (vs. 119 baseline; 19 pre-existing failures unchanged). Note: a separate OpenClaw-side concern surfaced in @Dongni-Yang's 2026-06-04 thread (in-sandbox gateway loses its HTTP listener while the process stays alive) is out of scope here — this fix only addresses the marker-file regression hulynn re-confirmed in #4710 for docker-driver sandboxes where the gateway legitimately runs on the host. Standalone deployments where the gateway runs in-container are unaffected: the marker is still created (just at the launch site instead of at startup), so the existing pgrep healthcheck behavior is preserved bit-for-bit. Fixes #4710.

In containers a failed in-process restart parks the gateway alive with its HTTP listener closed ("gateway startup failed: ... Process will stay alive"), which the PID-wait respawn loop (#2757) cannot observe. With the healthcheck marker now truthful, Docker correctly reports the container (unhealthy) forever — the remaining failure mode behind #4710. Two complementary defenses: - Pin gateway.reload.mode=hot in the generated sandbox config so plan-driven in-process restarts never close the listener; NemoClaw applies restart-class changes via rebuild or 'nemoclaw recover' instead. Host-side state restore already preserves the freshly generated gateway section (#5174), so the pin survives restores. - Add a serving watchdog to nemoclaw-start.sh: once the gateway has served at least one probe, sustained connection-refused on the dashboard port with the process still alive triggers TERM/KILL of the gateway PID so the existing respawn loop relaunches it. A pidfile written by PID 1 at every launch/respawn site keeps the watchdog aimed at the live gateway PID, and a cmdline identity check guards against PID reuse before killing. Also align the Dockerfile HEALTHCHECK liveness pattern with the recovery script's gateway-process pattern family, adding an anchored ^openclaw$ alternative for builds that truncate the rewritten process title, and document the hot-mode pin in the troubleshooting page. The #4503/#4710 marker coverage moves from test/nemoclaw-start.test.ts (at its size budget) into a focused gateway-health suite, converted from source-text assertions to behavioral launch-block and respawn-loop harnesses per the source-shape budget; the legacy size budget ratchets down accordingly.

In root mode a sandbox process could race-plant a symlink at that path between respawns; PID 1 (root) would follow it on open, yielding an arbitrary in-container root file write/chmod primitive. Write to a mktemp-owned 0600 file and atomically rename it into place: rename(2) replaces a planted symlink as a directory entry instead of following it, and the result stays owned by PID 1's uid. The sandbox user can at worst deny its own sandbox's self-healing (e.g. by pre-creating a directory at the path), which the watchdog already tolerates. Regression test plants a symlink to a sensitive file and proves the target is never opened, written, or chmod-ed. Also document the removal condition for the reload pin and watchdog next to the pin (an OpenClaw release that exits non-zero when a failed in-process restart cannot re-bind, proven by a wedge drill).

Open the pidfile once with O_NOFOLLOW so a single syscall both rejects symlinks and reads content — a strictly stronger assertion — and replace every remaining exists-then-read pattern in the gateway-health suite with a race-free read-and-catch helper. - The codebase growth guardrail requires the test size budget to stay monotonic against main, which ratcheted test/nemoclaw-start.test.ts to 5231 lines while this branch's merge resolution sat at 5237.
