fix(slm): code-sync/updater batch — protected release bundle, honest partial status, safe bootstrap (#16717, #16640, #16310) - #16789
Merged
Conversation
…ts live bundle or rollback (#16717) A forced "Resync from source" ran a delete-style rsync against autobot-slm-frontend with no exclude covering its staged-release layout (services/slm_frontend_build.py, #15610): current/previous (the served bundle and its rollback) and each dist-<build-id>/ directory (SLM_FRONTEND_RELEASE_KEEP retained builds) were never tracked in git, so a forced resync deleted them -- live bundle and rollback both -- with no earlier build to fall back to if the post-sync rebuild also failed. The same paths were also mislabeled "untracked ... left over" by the (pre-#16310) per-component drift walk, telling the operator a forced resync would only be cleaning up debris. services/deploy_artifacts.py gains the SLM frontend's release-layout vocabulary (SLM_FRONTEND_BUILD_PREFIX/CURRENT_LINK/PREVIOUS_LINK/ LEGACY_DIR/LEGACY_PREVIOUS_DIR) as the single source of truth -- the dependency-free base module both services/drift_checker.py's rsync excludes and now services/full_tree_drift.py already derive their build/deploy-artifact vocabulary from (#11459), rather than three separate restated literals. services/slm_frontend_build.py (the module that WRITES this layout) imports the same constants instead of defining its own, closing the loop. services/drift_checker.py protects autobot-slm-frontend's release names and dist-<id> prefix from both the rsync --exclude chokepoint (deploy_only_entries, reached by api/code_sync.py's _rsync_exclude_args for every resolve/preview) and the drift-walk classification (_is_expected_drift), so a forced or unforced resync and the drift report agree. Tests: tests/api/test_resolve_deletion_guard_13851.py exercises the REAL rsync dry-run (not a mock) against a fixture tree with three retained builds and live current/previous symlinks -- zero deletions -- and a control proving a genuinely-removed source file is still reported. services/drift_checker_test.py adds direct coverage of the classification (including an arbitrary, non-hardcoded build id) plus the same removed-file control. Single-issue rationale: batched with #16640 and #16310 per the coordinator -- all three are the code-sync/updater surface and ride one CI suite, but each is independently scoped and reviewable by commit.
…eploy failed (#16640) Host evidence, 2026-09-13: POST /code-sync/update-all finished with status completed, and the SLM self-node read code_status: up_to_date -- but the same run's co-located browser-service and npu-worker deploys both failed (ansible recap failed=1). The failures reached only a server-log line via _stage_log; nothing in the returned job/stage state, or the node's own reported status, said so. Root cause: _run_slm_stage's C4 fast path ("SLM control plane already at target commit") called _resolve_colocated_managed_services and then unconditionally set stage.status = CURRENT and advanced code_status to up-to-date, regardless of what that call reported -- because it reported nothing. _run_colocated_role_procedures logged per-role outcomes and discarded them. Both now return each failed role's "<name>: <reason>" line. The C4 path sets a new _StageStatus.PARTIAL (mirroring UpdateAllJob.status's existing "partial" value) naming every failure in stage.message, and skips _advance_node_version_if_fully_synced -- a role failure means the node is not fully synced whatever the file checksums say. _run_fleet_stage_or_already_current (no other outdated fleet nodes) and _run_fleet_stage (other nodes ARE outdated) both now read the slm_self_update stage before setting job.status, so the signal survives either pipeline shape instead of being overwritten by "completed" the moment there was other fleet work. CodeSyncView.vue distinguishes this partial cause from the pre-existing fleet-skip one (same job.status value, unrelated meaning, and the old banner's node count would read 0 and mislead) with its own banner, and gives the slm_self_update stage its own partial styling instead of falling back to "pending" gray. useCodeSync.ts's hand-written StageStatus union gains 'partial' -- the same class of gap #16610 review already found once for 'current'. Tests: a new file drives the C4 fast path and both status-dispatch functions through a failure, asserting stage/job status and the per-component detail survives both pipeline shapes; a pre-existing test mocking _resolve_colocated_managed_services with a bare AsyncMock() (a truthy default under the new contract) is fixed to return [] explicitly. Single-issue rationale: batched with #16717 and #16310 per the coordinator -- all three are the code-sync/updater surface and ride one CI suite, but each is independently scoped and reviewable by commit.
…-planner's bootstrap (#16310) update-all-nodes.yml's pre-flight code_source checkout used depth: 1 -- inconsistent with pre-flight-code-sync.yml and provision-fleet-roles.yml, which already fetch the same repo in full. services/sync_deletions.py:: compute_bootstrap_plan's own git log --diff-filter=AR runs over the WHOLE history to find every path git has ever added or renamed something into; against a shallow checkout it only ever saw the one commit the fetch kept, so "ever added" collapsed to "added in that commit" and a bootstrap that should have found years of genuinely-deleted files found almost none. Nothing about an empty, error-free plan looked like a problem, so ansible/roles/_shared/tasks/sync_deletions.yml wrote the marker anyway, permanently locking the target into diff-mode from a baseline missing most of its real deletions. Two changes: the pre-flight checkout drops depth: 1 (the root cause, fixed for every future run), and compute_bootstrap_plan now refuses to run at all on a shallow checkout via a new _is_shallow_repository check (git rev-parse --is-shallow-repository) -- an error plan routes through the ansible task's existing block/rescue, which does NOT write the marker on failure, so a run against a shallow checkout retries next time instead of silently succeeding empty. Same "fail loudly instead of succeeding wrong" contract compute_deletion_plan already has for an unknown previous commit. A host that already ran the bad bootstrap before this fix landed is a separate, harder problem -- there is no existing way to tell a marker a good bootstrap wrote from one an empty/shallow bootstrap wrote, and fixing that needs its own design (new marker metadata or a one-time fleet remediation), not a fold-in here. Filed as #16787, linked as a sub-issue of #16310. Tests: two disposable fixture repos, one fetched at --depth 1 (a REAL shallow checkout, not a hand-rolled stand-in) and its unshallowed control, prove the guard fires on the shallow one and clears once the exact same history is fetched in full; a third control proves an ordinary repo is unaffected. A playbook-YAML test pins that the pre-flight checkout task carries no depth: key. Two existing bounded-git-calls tests updated for the guard's added rev-parse call (2 -> 3). Single-issue rationale: batched with #16717 and #16640 per the coordinator -- all three are the code-sync/updater surface and ride one CI suite, but each is independently scoped and reviewable by commit.

Migrate existing shallow code_source checkouts.
Removing depth affects only new clones. An existing checkout created with depth: 1 remains shallow because these git update tasks do not unshallow it. compute_bootstrap_plan() then rejects the checkout, so deletion planning cannot proceed until the checkout is unshallowed.
After each successful code-source sync, run git fetch --unshallow when git rev-parse --is-shallow-repository returns true. Apply this to update-all-nodes.yml, pre-flight-code-sync.yml, and provision-fleet-roles.yml. Playbooks that import pre-flight-code-sync.yml inherit the correction.
The existing sync_deletions_test.py case covers the planner after an explicit unshallow operation. Add a playbook-wiring regression that requires this migration step in all three sync paths.

Preserve the Ansible failure text.
_role_procedure_result always includes output, but adds error only for explicit errors. Normal playbook failures therefore fall back to "see output" instead of reporting the failure reason.

Protect dist.previous from deletion.
_SLM_FRONTEND_RELEASE_NAMES omits SLM_FRONTEND_LEGACY_PREVIOUS_DIR. When a host still has the legacy rollback directory, deploy_only_entries() emits no rsync exclusion and _is_expected_drift() reports it as untracked. A delete-style resync can then remove the only rollback bundle before _remove_legacy_previous() has made it safe to remove.
Import and add SLM_FRONTEND_LEGACY_PREVIOUS_DIR to this set. Add assertions for the exclusion and expected-drift paths.

Show the skipped-node warning when nodes were skipped.
The backend stores skipped_fleet_nodes as an integer and sets the job status to partial when either this count is positive or slm_self_update is partial. Both conditions can occur in one run. When they do, colocatedPartial hides the skipped-node warning.
Render the warning when the count is positive:

Verified the #16310 'already merged' claim against One thing worth surfacing before this merges: #16310's AC5 is host-behavior ("after one update through the GUI, the drift check shows 0 removed-from-source files on all four components") — that can't be verified from code or CI, only from an actual host run. Everything else in the issue is now code-complete, but per the repo's own standing rule (host-behavior ACs need host evidence, not merge evidence), #16640: verified both pipeline shapes actually check the PARTIAL status before falling through to a clean terminal state — |
…e-size ceilings (#14236) code_sync.py, drift_checker.py, drift_checker_test.py and sync_deletions_test.py are all grandfathered at exact ceilings; the earlier commits in this batch grew each of them past its recorded size. Per #14236's contract a grandfathered file may not grow, so this pays for the growth the same way the #15881/_resume_plan.py and #16713/code_sync_paths.py precedents did: move the new code out rather than bump the ceiling. - api/code_sync.py: _run_colocated_role_procedures moved to a new api/_colocated_role_procedures.py (TYPE_CHECKING-only import back for the UpdateAllStage annotation, no runtime circular import). Trimmed several multi-line #16640 comments to match this repo's own no-issue-reference commenting convention while at it. File drops to 6025 lines; both ceiling registries updated in lockstep (scripts/python_file_size_known_large.py, repo_tests/python_file_size_ratchet_baseline.py). - services/drift_checker.py: the new SLM-frontend release-layout excludes and predicate moved into services/deploy_artifacts.py (already the dependency-free SSOT the rest of this vocabulary lives in), imported as a module rather than by name so the single import line never needs wrapping. Two pre-existing docstring paragraphs reflowed to reclaim a couple of lines. File holds exactly at its 839 ceiling. - services/drift_checker_test.py / tests/services/sync_deletions_test.py: the new test classes/functions split into their own files (drift_checker_slm_frontend_test.py, sync_deletions_shallow_bootstrap_test.py), duplicating each file's existing dynamic-import test harness rather than sharing it — the same pattern already used by test_resolve_deletion_guard_13851.py and test_worker_component_resolve_12450.py for drift_checker.py. Verified: python3 scripts/check_python_file_size.py --audit-ceilings is clean across the whole tree; black/isort/flake8 clean on every touched file; 173 tests pass across the affected files (drift_checker_test.py x2, sync_deletions_test.py x2, the #16640 colocated-failure tests, and the #12202 marker regression test).
…the shallow-clone bootstrap tests CI (python-suite shard 12/12) failed: tests/api/conftest.py's pytest_runtest_call hookwrapper patches asyncio.create_subprocess_exec process-wide for the whole pytest session once that conftest loads, not just for tests under tests/api/ -- so a shard that also collects any tests/api/ file blocks the real git subprocess these three new tests exist to exercise (compute_bootstrap_plan's --is-shallow-repository check). Bypassed with the same pattern tests/api/test_resolve_deletion_guard_13851.py already uses for real rsync: capture the real asyncio.create_subprocess_exec at module import time (before any per-test hook can patch it) and restore it for the duration of each compute_bootstrap_plan call via patch.object. Reproduced locally (pytest tests/api/test_resolve_deletion_guard_13851.py tests/services/sync_deletions_shallow_bootstrap_test.py failed before this fix, 29 passed after) and re-ran the full file in isolation (25 passed).
…_build.py (#16717) CI (python-suite shard 8/12) failed: repo_tests/slm_frontend_publish_contract_test.py cross-checks the Ansible/shell/Python SLM publishers against a shared contract via source-text regex, and its "builds into a fresh directory" clause for the python implementation matches literal source text containing `_BUILD_PREFIX` (#15724) -- the private, underscore-prefixed name the constant had before today's #16717 refactor moved its definition into services/deploy_artifacts.py. The import aliases (`as BUILD_PREFIX`, `as CURRENT_LINK`, ...) dropped the leading underscore all five constants had under their original local definitions, silently breaking that regex even though the runtime behaviour never changed. Restored the underscore on every alias and usage site (_BUILD_PREFIX, _CURRENT_LINK, _PREVIOUS_LINK, _LEGACY_DIR, _LEGACY_PREVIOUS_DIR) -- the module's own privacy convention for these, unrelated to the ceiling refactor that moved where they're defined. Verified: repo_tests/slm_frontend_publish_contract_test.py passes (9/9); the full slm-frontend-layout test surface (staged build, legacy-previous, deployed-commit marker, atomic publish, staged publish) passes 46/46 in one run; black/isort/flake8 and the file-size audit clean.

…s.path assumption (#16816) audit_api_wiring_test.py loads this file via importlib.spec_from_file_location + exec_module rather than running it as `python3 scripts/audit_api_wiring.py`, so the interpreter never adds this file's own directory to sys.path the way a directly-executed script gets for free. The bare `from dead_surface import report_dead_surface` then raised ModuleNotFoundError under pytest, blocking collection and the pre-push hook -- pre-existing on this branch, unmasked while refreshing past #16789's registry changes for the unrelated ratchet collision. Reflowed the adjacent SLM_BACKEND comment to 120 columns to pay for the added line in-file; audit_api_wiring.py holds at its ceiling of 895.

Closes #16717, #16640. Refs #16310.
Thinking Path
Assigned as one batch (coordinator autobot-ai-71): all three are the builtin code-sync/updater surface and share one CI suite. Investigated each independently before writing anything, since #16310 in particular turned out to already be mostly landed.
#16717: traced the forced-resync deletion through
api/code_sync.py's rsync chokepoint (_rsync_exclude_args→deploy_only_entries/owned_subtreesfromservices/drift_checker.py) and confirmedautobot-slm-frontend's staged-release layout (current/previoussymlinks,dist-<build-id>/directories,services/slm_frontend_build.py, #15610) had no exclude covering it anywhere in that chain — neither the rsync side nor the (older, per-component) drift-walk classificationservices/drift_checker.py::_is_expected_driftuses. The newerservices/full_tree_drift.py(built for #16310) already classified these correctly, but via its own restated literal, not this module's.#16640: traced
_run_slm_stage's C4 "already current" fast path and found it called_resolve_colocated_managed_services, which called_run_colocated_role_procedures, which logged every per-role outcome via_stage_logand returned nothing — so a failure never reached anything the job/stage status or the node'scode_statusread. The fast path setstage.status = CURRENTand advancedcode_statusto up-to-date unconditionally, regardless of what the co-located roles actually did.#16310: an
Exploreagent first mapped the whole area and found most of the acceptance criteria already landed onorigin/main(the deletion planner, host-state filtering, three/four-way drift labeling, legacydist.previous/npu_workers.yamlcleanup) — confirmed viagit merge-base --is-ancestorbefore touching anything, to avoid re-implementing merged work. The one gap still open per the issue's own last comment:update-all-nodes.yml's pre-flightcode_sourcecheckout useddepth: 1, andservices/sync_deletions.py::compute_bootstrap_plan'sgit log --diff-filter=AR(which needs the WHOLE history) silently returned an almost-empty plan against it — no error, so the caller wrote the deletion marker anyway, permanently locking the target into diff-mode from a bad baseline.What Changed
#16717 —
services/deploy_artifacts.pygains the SLM frontend's release-layout vocabulary (SLM_FRONTEND_BUILD_PREFIX/CURRENT_LINK/PREVIOUS_LINK/LEGACY_DIR/LEGACY_PREVIOUS_DIR) as the single source of truth — the same dependency-free base moduledrift_checker.py's rsync excludes and nowfull_tree_drift.pyalready derive their build/deploy-artifact vocabulary from (#11459), rather than three separate restated literals.services/slm_frontend_build.py(the module that writes this layout) imports the same constants instead of defining its own.services/drift_checker.pyprotects the release names anddist-<id>prefix in bothdeploy_only_entries(reached by every rsync--excludebuild, forced or previewed) and_is_expected_drift(the per-component drift walk's classification).#16640 —
_run_colocated_role_procedures/_resolve_colocated_managed_servicesnow return each failed role's"<name>: <reason>"line instead of discarding it._StageStatusgainsPARTIAL(mirroringUpdateAllJob.status's existing"partial"). The C4 fast path sets it and skips_advance_node_version_if_fully_syncedon any co-located failure. Both_run_fleet_stage_or_already_current(no other outdated nodes) and_run_fleet_stage(other nodes ARE outdated) now check theslm_self_updatestage before settingjob.status, so the signal survives either pipeline shape — the latter previously overwrotejob.statusunconditionally based only on skipped fleet nodes.CodeSyncView.vuegets its own banner for this partial cause (the pre-existing fleet-skip banner's node count would read 0 and mislead) plus proper stage styling instead of falling back to gray/"pending";useCodeSync.ts's hand-writtenStageStatusunion gains'partial'(the same class of gap review already found once for'current').api/code_sync.pysits at its #14236 file-size ceiling;_run_colocated_role_proceduresmoved to a newapi/_colocated_role_procedures.py(the same #15881/_resume_plan.pyand #16713/code_sync_paths.pyprecedent — pay for growth by moving code out, never by raising the ceiling) to make room for reporting failures instead of only logging them.services/drift_checker.pyand its two test files hit the same ceiling from the #16717 work; the new release-layout predicate/excludes moved intoservices/deploy_artifacts.py(already the dependency-free SSOT the rest of that vocabulary lives in) and the new test classes moved to their own files (drift_checker_slm_frontend_test.py,sync_deletions_shallow_bootstrap_test.py) rather than growing the grandfathered originals. Both ceiling registries (scripts/python_file_size_known_large.py,repo_tests/python_file_size_ratchet_baseline.py) updated in lockstep forcode_sync.py's new, smaller size.#16310 —
update-all-nodes.yml's pre-flight checkout dropsdepth: 1(root cause, matchespre-flight-code-sync.yml/provision-fleet-roles.yml, which already fetch in full).services/sync_deletions.py::compute_bootstrap_plangains_is_shallow_repository(git rev-parse --is-shallow-repository); a shallow checkout now returns anerrorplan, which routes through the ansible task's existing block/rescue — the rescue does not write the marker, so the next run retries once the checkout is full-depth, the same "fail loudly instead of succeeding wrong" contractcompute_deletion_planalready has for an unknown previous commit. Remediating a host that already wrote a marker from the old, silently-broken bootstrap is a separate, harder problem (no existing way to tell that marker from a good one) — filed as #16787, linked as a native sub-issue of #16310, not folded in here.Verification
tests/api/test_resolve_deletion_guard_13851.py: new tests exercise the real rsync dry-run (not a mock, matching this file's existing pattern for backend/npu-worker) against a fixture tree with three retained SLM-frontend builds and livecurrent/previoussymlinks — zero deletions — plus a control proving a genuinely-removed source file is still reported.services/drift_checker_test.py: direct coverage of the classification, including an arbitrary/non-hardcoded build id (proving a real prefix match, not a restated literal) and the same removed-file control.tests/api/test_code_sync_update_all_colocated_failure_16640.py(new): drives the C4 fast path and both status-dispatch functions through a co-located failure, asserting stage/job status and the per-component detail survive both pipeline shapes (no other outdated nodes, and other nodes outdated too).tests/api/test_slm_deployed_commit_marker_12202.py: pre-existing test mocking_resolve_colocated_managed_serviceswith a bareAsyncMock()(a truthy default under the new contract, which would have flipped it to PARTIAL) fixed to return[]explicitly.tests/services/sync_deletions_test.py: two disposable fixture repos — one fetched at--depth 1(a real shallow checkout, not a hand-rolled stand-in) and its unshallowed control — prove the guard fires and clears against the identical history; a third control proves an ordinary repo is unaffected. A playbook-YAML test pins that the pre-flight checkout task carries nodepth:key. Two pre-existing bounded-git-calls tests updated for the guard's addedrev-parsecall (2 → 3 git calls).services/drift_checker_test.py,tests/services/sync_deletions_test.py); full suite pending CI.api/code_sync.py's update-all/drift-resolve endpoints andsync_deletions.py's bootstrap guard are evidenced entirely through the fixture-repo/dry-run tests above and CI.Model Used
