fix: preserve PUT lock failure diagnostics (#9062 )

* fix: preserve PUT lock failure diagnostics Propagate the request operation into spawned PUT commit tasks so lock failures retain their metric attribution. Record bounded lock error classifications without exposing lock resources. Co-Authored-By: heihutu <heihutu@gmail.com> Co-Authored-By: zhi22915 <qiuzgang@gmail.com> * test: remove redundant clone in PUT lock test Co-Authored-By: heihutu <heihutu@gmail.com> Co-Authored-By: zhi22915 <qiuzgang@gmail.com> * fix: bound PUT commit context stack usage Pin the commit future before wrapping it with request context to reduce stack pressure in PUT callers.

@@ -32,7 +32,7 @@ A job runs on `ubuntu-latest` unless it has one of these reasons, and the reason

 Jobs that do only the following have no reason to be self-hosted: shell or Python scripts, `cargo fmt`, `cargo deny`, typos, actionlint, API calls (`gh`, dependency review, issue and stale bots, CLA checks), downloading an artifact and running a prebuilt binary, or a `cargo build -p rustfs` with its own cache key. `e2e-distributed.yml` and `e2e-upgrade.yml` build the server and the `e2e_test` harness on `ubuntu-latest` inside their budgets, so "it compiles something" alone is not a reason.

-The functional chain's `prepare` and `complete-chain` jobs, the performance runner availability check, and runner hygiene use `ubuntu-latest`: they inspect APIs or artifacts, not the lab hosts. The actual functional and performance suites remain on their lab runners. Functional-chain health collection stays on the operator-managed `smoke-testing` runner as part of the automation environment. Docker image packaging also uses `ubuntu-latest` for both musl and glibc variants; it downloads release binaries rather than compiling the workspace, and still sets up QEMU and Buildx explicitly.
+The functional chain's `prepare` and `complete-chain` jobs, the performance runner availability check, and runner hygiene use `ubuntu-latest`: they inspect APIs or artifacts, not the lab hosts. The actual functional and performance suites remain on their lab runners. Functional-chain health collection uses `ubuntu-latest` so a lab outage cannot also stop its independent monitor.

 Moving these jobs off AKS reduces capacity demand, not necessarily the Azure bill immediately. VM costs fall only when nodes scale down or smaller capacity replaces them.

-//! Dual-stack differential: one `rustfs` binary, two processes, one SDK script (rustfs/backlog#2740).
-//!
-//! Stack A always runs `RUSTFS_S3_STACK=legacy`. Stack B runs the value of `RUSTFS_E2E_STACK_B`
-//! (default `legacy` until the gateway stack is assembled), and `RUSTFS_E2E_STACK_B_REGION`, when
-//! set, starts B in another region so that a difference can be injected by hand. Both servers
-//! answer the script in `scenarios`, which covers every operation of `impl S3 for FS`; `compare`
-//! reports each `(op, field, a, b)` on which the answers differ, and every run writes its report
-//! to `<target>/dual-stack/<run>.json`. Two processes, not two embedded servers: bucket metadata
-//! is process-global, so two stacks in one process would read each other's buckets.

Hauser Zhi	dcbec68d45	fix: preserve PUT lock failure diagnostics (#9062 ) * fix: preserve PUT lock failure diagnostics Propagate the request operation into spawned PUT commit tasks so lock failures retain their metric attribution. Record bounded lock error classifications without exposing lock resources. Co-Authored-By: heihutu <heihutu@gmail.com> Co-Authored-By: zhi22915 <qiuzgang@gmail.com> * test: remove redundant clone in PUT lock test Co-Authored-By: heihutu <heihutu@gmail.com> Co-Authored-By: zhi22915 <qiuzgang@gmail.com> * fix: bound PUT commit context stack usage Pin the commit future before wrapping it with request context to reduce stack pressure in PUT callers.

hector	589b499e3b	ci(ft,heal,chain): FT gate 54, heal budget, and a temporary performance lane disable (#9057 ) * ci(ft): update the lane gate to the 54-case manifest with scenario F auto-testing #118/#119 added FT scenario F and case B5, so the lane now runs 54 cases over scenarios A,B,C,C2,D,E,F and passes 54/54 — but the workflow gate still pinned the 44-case A-E manifest and failed the report step. Align the gate and the contract-test fixture with the 54-case manifest. * ci(heal): give heal a 90-minute run budget inside a 120-minute job The heal task was still progressing (scanned 494 -> 571+, failed=0) when the 45-minute step cap killed it, so the verification steps never ran and the lane produced invalid evidence (chain 40796474356). The step budget is now 90 minutes, and the job-level budget rises from 60 to 120 minutes so the enclosing job cannot cancel the raised step budget. The timeout contract now records heal as the exception to the shared 60/45 baseline. * ci(chain): force the performance probe offline while pf-testing is broken The pf-testing environment is temporarily broken, so every nightly chain would end red in the performance lane. performance is required=false in scheduled-validations.json, so forcing the probe's performance_ready output to offline takes the chain through its designed skip path: the lane job is skipped, aggregate receives --allow-skipped performance, and the report records the optional-lane skip with its reason. Marked TEMPORARY; restore the probe once the environment is healthy again. * test(table): drop a stale workflow-comment pin left by #9059 #9059 rewrote the table suite step comments but kept the assertion for the old '# Red only for harness/environment breakdowns' line, so test_security_workflow.py fails against current main. The semantics stay pinned by the continue-on-error and HARNESS_OK assertions.	2026-10-30 14:03:22 +08:00
Mathew Beane	69f8e364b0	fix(audit): emit entries for multipart parts and bucket config writes (#9067 ) * fix(audit): replay queued payloads for internal event names Audit entries are persisted by the store targets and read back through serde. Three internal events (CreateMultipartUpload, AbortMultipartUpload, DeleteObjects) serialized to a string that EventName::deserialize rejected, so every queued entry for them was dropped on replay. Read the persisted event name through a lenient deserialize_with function; EventName's own Deserialize and parse stay strict because they also back notification configuration. * fix(audit): emit entries for multipart parts and bucket config writes UploadPart, UploadPartCopy, AbortMultipartUpload and the mutating bucket configuration operations never produced an audit entry: the audit path required a bucket notification event and these operations have none, or (AbortMultipartUpload) never built a helper. Add an audit-only OperationHelper constructor that builds no notification event and wrap the S3 handlers for these operations with it. Operations without a notification event use one coarse audit-only event name, with the operation in api.name. --------- Co-authored-by: Hauser Zhi <housemecn@gmail.com>	2026-10-30 11:58:54 +08:00

Chris An	dacb003856	ci: let failed-job reruns reuse the producer's test archives (#9071 ) Since #9059 the shared test archives and debug binaries are named with the run attempt, and the archive identity binds the attempt. A "Re-run failed jobs" attempt does not rerun the successful producer, so its consumers look for <name>-2, fail with "Artifact not found", and every flaky test forces a full rerun. Give those artifacts one name per run, overwrite them when a producer does rerun, and bind the archive identity to the run instead of the attempt. Source, tree, lock, toolchain and environment stay bound, and an archive from another run is still rejected.	2026-10-30 11:16:10 +08:00
Chris An	c67f9fc377	ci: qualify workspace packages that share a name with a dependency (#9065 ) The planned package list is passed to cargo as bare -p names. The zstd compat crate is named zstd so it can patch crates.io, and with zstd 0.14.3 also locked, cargo rejects -p zstd as ambiguous, failing Workspace Lint and Build on main since #9059. Qualify such names with the local version from Cargo.lock, and fail loudly if even that cannot disambiguate.	2026-10-30 06:09:42 +08:00
