From c8fe45562e6c0e12c1b36453dbe352cc2aab0ab5 Mon Sep 17 00:00:00 2001 From: "Molecule AI Dev Engineer A (Kimi)" Date: Sun, 14 Jun 2026 16:04:27 +0000 Subject: [PATCH 1/8] fix(provisioner,e2e): #2851 advertise Docker gateway IP when platform is containerized MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When the platform itself runs inside an act_runner Docker container (lifecycle-real job, MOLECULE_IN_DOCKER=true), a workspace that advertises http://localhost: is unreachable from the platform container — localhost resolves to the platform container, not the workspace container. Changes: - provisioner: workspaceAdvertiseURL() now reads MOLECULE_WORKSPACE_ADVERTISE_HOST, defaulting to localhost. This lets an operator point the runtime at the Docker host/gateway IP. - local-provision-e2e.yml lifecycle-real job: export MOLECULE_WORKSPACE_ADVERTISE_HOST= so the real-image E2E workspace advertises the gateway IP. - E2E harness: accept PLATFORM_HOST_IP as a host-reachable URL host in addition to 127.0.0.1/localhost. - Tests: expand TestWorkspaceAdvertiseURL to cover the env override and empty-env default.

ProxyA2A's resolveAgentURL then rewrote that to http://ws-:8000 (the internal Docker hostname) when platformInDocker, and isSafeURL rejected it as 'workspace URL is not publicly routable' — the lifecycle-real assertion {"error":"workspace URL is not publicly routable"} followed. Fix: StartWorkspace now uses the new resolveStartWorkspaceHostURL helper, which calls workspaceAdvertiseURL(hostPort) for the host (env override → localhost) and only swaps the port if Docker bound a different one. The default behavior (no env var) is unchanged (localhost) so the pre-#2851 host-direct platform path is preserved. The containerized-platform path now persists http://172.18.0.1: in the DB, which: - Doesn't trigger the 127.0.0.1→ws- rewrite in resolveAgentURL - Resolves dev-mode SSRF relaxation (MOLECULE_ENV=development allows RFC-1918 private ranges per the existing dev/saas split in isPrivateOrMetadataIP) The E2E shell assertion in test_local_provision_lifecycle_e2e.sh already accepts PLATFORM_HOST_IP (added in c8fe4556); no shell change needed — the Go fix is sufficient. Test: TestResolveStartWorkspaceHostURL covers: - default localhost (no env override) - env override, no bound-port swap - env override, bound port differs (inspect-fallback path) - env override, bound port matches (no-op) - no env override, bound port swap (legacy 127.0.0.1 case) All 5 subtests pass; full provisioner suite 0.094s.

Two-part fix (per PM dispatch 05d36fd7): 1. **workspace-server/internal/provisioner/provisioner.go**: extract `buildStartWorkspaceEnv(cfg, hostPort)` helper. Start() now calls it instead of inlining the env-construction. The helper injects MOLECULE_WORKSPACE_URL= (the host-port URL, not the runtime's listen-port 8000 fallback) so the runtime's resolve_workspace_url (which honors MOLECULE_WORKSPACE_URL at highest precedence) returns the same host-port URL the provisioner persisted. 2. **workspace-server/internal/handlers/registry.go**: generalize the Register handler's URL-preservation CASE in the upsert. The previous CASE only matched `http://127.0.0.1%` — my round-3 fix changed the provisioner to default to `http://localhost:` (via workspaceAdvertiseURL), so the runtime's `http://localhost:8000` (fallback when env propagation is broken) overwrote the provisioner's correct URL. The new CASE matches both prefixes (127.0.0.1 + localhost) AND requires the port to not be 8000 (so the runtime's wrong fallback is NOT preserved — EXCLUDED.url wins in that case, but the round-3 fix's behavior is preserved because the runtime's CORRECT URL matches the provisioner's). 3. **Tests**: added TestBuildStartWorkspaceEnv (3 subtests): - default localhost → MOLECULE_WORKSPACE_URL=http://localhost:41751 - env override 172.18.0.1 → http://172.18.0.1:33605 - env injection comes AFTER buildContainerEnv (so docker -e last-wins: the platform-injected URL beats any same-key env in buildContainerEnv) All 3 PASS. Full provisioner suite 0.092s. SSRF unchanged (the CASE only preserves EXISTING urls that pass the provisioner's existing validateAgentURL; the runtime's URL is still subject to the same SSRF check on the new path).

Go's compiler doesn't parse those (they're literal text), so the resulting SQL string sent to Postgres contained lines starting with `//` — which Postgres doesn't recognize as a comment marker (Postgres standard is `--`). Result: pq: syntax error at or near '//' → Register returns HTTP 500, breaking the required stub lane that 8245e50c was supposed to un-break. The fix is exactly what Researcher's #11798 follow-up suggested: `//` → `--` inside the Go raw-string SQL literal. The Go compiler still sees the same string (it's just a different character sequence); Postgres now sees valid line comments and parses the CASE correctly. 3 new integration tests (all run against REAL Postgres via integrationAuthDB) cover the CASE's three contract clauses: 1. **TestIntegration_RegistryRowState_RegisterPreservesProvisionerHostPort**: pre-set rows to http://localhost:41751 / http://127.0.0.1:33605, re-register with the same or different host-port URL, assert the existing row's URL is preserved (the load-bearing fix that prevents the round-3 11798 gap). 2. **TestIntegration_RegistryRowState_RegisterOverwritesRuntime8000**: pre-set to http://127.0.0.1:8000, re-register with http://localhost:8000, assert the row is overwritten to http://localhost:8000 (the CASE excludes port 8000 — the runtime's wrong fallback is NOT preserved). Also the reverse (existing localhost:8000 + runtime 127.0.0.1:8000) for symmetry. 3. **TestIntegration_RegistryRowState_RegisterOverwritesNonLocalhost**: pre-set to http://192.168.1.100:8080 (non-localhost), re-register with http://localhost:41751, assert the row is overwritten (the CASE only matches localhost/127.0.0.1 prefixes — non-localhost URLs in the row get overwritten, defense-in-depth against SSRF vectors snuck into the row pre-#1130). Also updated the existing registerUpsertSQL constant to match the new SQL (// -> -- + the new CASE shape) and added two test helpers: insertWorkspaceWithURL (sets url on insert) and urlOf (reads the row's url after upsert). All paths exercised against REAL Postgres. Build clean. `go vet` clean.

The current state had: - My SQL fix (// -> -- inside the raw string) — present - The OLD URL-cache path (strings.HasPrefix(dbURL, 'http://127.0.0.1')) instead of Kimi's isProvisionerHostPortURL(dbURL) — REGRESSED back to the round-3 narrow prefix, defeating the round-3 localhost-pref fix in the URL-cache code path. This commit restores Kimi's: 1. isProvisionerHostPortURL(u) helper (handles both 127.0.0.1 and localhost prefixes; port != 8000; trailing-port extraction via strconv.Atoi) 2. URL-cache path uses the helper (not just 127.0.0.1) 3. strconv import Without this, the URL-cache preservation works for 127.0.0.1 only (the round-3 localhost default would NOT be preserved) — half of the round-3 fix would be silently undone.
