From 2777d21efa8ba195151f2248cf168f8c8455716d Mon Sep 17 00:00:00 2001 From: "Molecule AI Dev Engineer B (MiniMax)" Date: Sun, 14 Jun 2026 15:28:55 +0000 Subject: [PATCH 1/3] fix(provisioner#24 PR-B): real Gitea TemplateAssetFetcher + wire (no stubs) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PR-B of the RFC #2843 #24 keystone (per the driver design-owner dispatch). Real production Gitea fetcher + wire-up so collectCPConfigFiles reconciles EVERY boot (not just first provision) for SaaS workspaces whose runtime has a template repo. Self-host callers see no behavior change (the fetcher field is nil; the SCAFFOLD gate in collectCPConfigFiles treats nil as 'skip the fetcher'). WHAT THIS LANDS: - NEW workspace-server/internal/provisioner/gitea_template_assets.go: - giteaTemplateAssetFetcher{baseURL, token, httpClient} satisfying provisioner.TemplateAssetFetcher - NewGiteaTemplateAssetFetcher constructor (httpClient may be nil — the constructor substitutes a 30s-timeout default) - parseTemplateIdentity parses '/@' — 10 cases covered by TestParseTemplateIdentity (happy paths + 6 malformed-identity failures) - Load: GET {baseURL}/api/v1/repos///archive/' header, stream-decode gzip + tar, strip archive top-level dir prefix - stripArchiveTopDir rejects traversal sequences (../) and top-level-only entries (the load-bearing defense against a malicious tarball trying to land files at '../etc/passwd') - Fail-closed on transport / extract / parse errors. NO size cap on the fetcher (consumer-side 16MiB cap from #2845 acbc0da9 is the real bound; this matches the dispatch's 'NO size cap' on the fetcher) - workspace-server/internal/handlers/runtime_registry.go: - New field on manifestEntry: Ref (e.g. 'main' or a pinned tag) - New templateRepoByName map (runtime -> (repo, ref)) populated by initTemplateRepoByName alongside initKnownRuntimes - New templateIdentityForRuntime(runtime) -> (string, bool) helper: returns '@' for template-backed runtimes, ('', false) for external / kimi / kimi-cli / mock / unknown - Single-expression wrapper templateIdentityForRuntimeOrEmpty for the buildProvisionerConfig call site - workspace-server/internal/handlers/workspace.go: - New WorkspaceHandler.giteaTemplateFetcher field (provisioner.TemplateAssetFetcher, nil = no fetcher wired) - New SetGiteaTemplateFetcher setter (mirrors SetCPProvisioner pattern — main.go wires a real one, tests pass a stub) - workspace-server/internal/handlers/workspace_provision.go: - buildProvisionerConfig now sets: - cfg.TemplateIdentity = templateIdentityForRuntimeOrEmpty( payload.Runtime) — derived from the manifest - cfg.TemplateAssetFetcher = h.giteaTemplateFetcher — wired from main.go, nil = self-host default - This is the SINGLE source of truth for WorkspaceConfig across BOTH first-provision AND restart/auto-heal paths (both call buildProvisionerConfig) — so 'every boot' reconciliation is automatic, per the dispatch's requirement. NEW TESTS (all pass): - TestGiteaTemplateAssetFetcher_HappyPath: real .tar.gz fixture (config.yaml + prompts/system.md + agent-skills/seo-audit/SKILL.md + agent-skills/seo-audit/manifest.yaml) → all 4 assets returned. Per the dispatch: 'must FAIL if skills dropped' — this test asserts the skill files explicitly. - TestGiteaTemplateAssetFetcher_AllowsOnlyAllowlistedPaths: tar contains BOTH allowlisted (config.yaml, prompts/*, agent-skills/*) AND non-allowlisted (CLAUDE.md, MEMORY.md, USER.md, .claude/sessions/*, adapter.py) — only the allowlisted are returned. The blast-radius guard. - TestGiteaTemplateAssetFetcher_FailsClosedOnHTTPError: 500 → error (not silent empty result) - TestGiteaTemplateAssetFetcher_FailsClosedOnTransportError: bad port → error (not silent empty result) - TestGiteaTemplateAssetFetcher_RejectsEmptyToken: empty token → error (security guard against anonymous requests) - TestParseTemplateIdentity: 10 sub-cases (happy + 6 malformed) - TestStripArchiveTopDir: 10 sub-cases (happy + traversal + top-level + dot + dotdot-in-name) - TestTemplateIdentityForRuntime: claude-code resolves to 'owner/repo@ref'; BYO-compute meta-runtimes (external / kimi / kimi-cli / mock / unknown) all return ('', false) - TestTemplateIdentityForRuntimeOrEmpty: single-expression wrapper test (skipped when manifest.json not found, like the existing TestRealManifestParses) LOCAL VALIDATION: - go test ./internal/provisioner/ -> clean (0.09s, all 5 new Gitea tests pass + all existing) - go test ./internal/handlers/ -> clean (25.2s, all 2 new template-identity tests skip-or-pass + all existing) - go vet ./... -> clean - go build ./... -> clean - (golangci-lint not runnable locally — Go 1.22 vs 1.25 mismatch) FOLLOW-UPS (NOT in this PR per the dispatch's 'no stubs' rule): - main.go needs to call h.SetGiteaTemplateFetcher(...) with a real giteaTemplateAssetFetcher (baseURL + per-identity READ-ONLY Gitea PAT from Infisical SSOT). The handler-side wire is ready; main.go is the call site. (PR-B is the engine work; main.go wiring is a follow-up because Infisical SSOT threading per #2676 program is its own work item.) - E2E test (dispatch mentioned) — needs a real Gitea fixture or a Gitea docker-compose; out of scope for this PR.

Two pieces landed in one commit: 1. workspace_provision.go:init() now calls initTemplateRepoByName() alongside initKnownRuntimes(). The branch's earlier commit (ef8280e2, RFC #2843 #24 PR-B) added the function + the templateRepoByName map + the templateIdentityForRuntime lookup + the manifestEntry Ref field, but the prod-init call was missing — so the map stayed empty at boot and cfg.TemplateIdentity was always '' for template-backed runtimes (claude-code, hermes, etc). The SCAFFOLD gate in collectCPConfigFiles treats empty TemplateIdentity as 'skip the fetcher', which meant the entire PR-B mechanism stayed inert. This commit closes the gap. 2. cmd/server/main.go wires the Gitea TemplateAssetFetcher. Reads MOLECULE_TEMPLATE_REPO_TOKEN env var (new, distinct from the existing MOLECULE_TEMPLATE_GITEA_TOKEN which is for the template cache — different feature). nil-if-empty + WARN: if unset, logs 'fetcher disabled (self-host default)' and the SCAFFOLD gate preserves pre-scaffold behavior. baseURL has a production default (https://git.moleculesai.app) but is overridable via MOLECULE_GITEA_BASE_URL for staging / per-deployment Gitea mirrors. The 'destructive reverts' PM flagged in earlier dispatches were in the branch's history but not the current diff (clean +792/-0 on the pre-rebase HEAD). The rebase onto current origin/main (9e8eefad66f4) was conflict-free, so nothing destructive to drop.

Two pieces: 1. **reconcile-on-every-boot fix in initTemplateRepoByName**: The previous implementation added entries to templateRepoByName but did NOT clear stale ones. Calling init twice with a manifest that had a runtime removed would leave the removed runtime's entry in the map — the fetcher would attempt a no-longer-existing repo. Fixed by resetting the map at the start of every call, then re-populating from the current manifest. Idempotent for the same manifest; reconciles stale entries across manifest changes. 2. **two new tests pinning the prod-init contract**: - TestInitTemplateRepoByName_PopulatesMap_FromTempManifest — writes a temp manifest.json (via WORKSPACE_MANIFEST_PATH), calls init, asserts the map is populated for the shipped runtimes AND templateIdentityForRuntime returns the expected "@". The load-bearing test PM required: 'Keep a test asserting the prod-init path populates it (so this can't regress to test-only)'. - TestInitTemplateRepoByName_ReconcilesStaleEntries — pins the every-boot reconcile: init with manifest A then with manifest B (B missing a runtime that A had) must leave the map with ONLY B's entries. Without the reset fix, hermes would still be resolvable after the second init. The reset fix in (1) is what makes this test pass. The existing TestTemplateIdentityForRuntime / TestTemplateIdentityForRuntimeOrEmpty are SKIP in this cwd (manifest.json not discoverable from test cwd) but the new tests use t.TempDir() + t.Setenv('WORKSPACE_MANIFEST_PATH', ...) so they run in any cwd.
