From 6837b725f3cb7c4849cb99814f6fcffe69818b7e Mon Sep 17 00:00:00 2001 From: Andrei Kvapil Date: Fri, 22 May 2026 13:18:02 +0200 Subject: [PATCH 01/21] ci(integration): switch linstor-client install to GitHub tarball The previous apt-get install path failed on ubuntu-latest (noble): LINBIT ships linstor-client debs only for Debian (bookworm/bullseye/buster/trixie) and on the LINBIT PPA, neither of which covers noble. `apt-get install linstor-client` exits with "Unable to locate package". The PyPI route is also a dead end: only `python-linstor` is published there; `linstor-client` and the bare `linstor` package name are NOT on PyPI, so `pip install linstor-client` exits with "No matching distribution found". Install path that actually works on ubuntu:24.04 (validated locally in a fresh container): 1. pip install `python-linstor==1.27.1` + `argcomplete` from PyPI for the runtime deps. 2. pip install the v1.27.1 tarball directly from https://github.com/LINBIT/linstor-client/archive/refs/tags/v1.27.1.tar.gz with `--no-deps` to bypass an upstream setup.py typo (missing comma joins `python3-setuptools` + `python-linstor` into one malformed requirement). Version pin is deliberate: tests/integration/group_h_test.go explicitly documents that it is written against linstor-client 1.27.1 CLI behaviour.

Both labels are registered org-wide on the cozystack org by the CNCF infra team — no per-repo setup needed. 96 GB RAM is enough headroom for real-DRBD QEMU stands (Talos VMs in .work/, ~50 GB RAM, KVM nested virt), so this also lifts the cli-matrix tier into CI once the workflow drives `make e2e` explicitly. Drop continue-on-error: true (added when the runner was the cramped ubuntu-latest) — with real hardware the e2e job should gate the PR again.

Sync it with `integration.yml`'s GitHub tarball approach so both PR and push runs share the same install rationale. 2. `integration.yml` had its `pull_request:` trigger restored manually; that duplicates with the consolidated pipeline (both workflows fired on every PR). Drop it again — push-only on main, per the original PR #6 design. 3. Drop `continue-on-error: true` from the lint job. Lint debt is cleared in the same PR (the cherry-picked PR #8 commits), so the muzzle is no longer needed — lint should gate again. 4. Drop `continue-on-error: true` from the integration job. The tarball install path now works, so integration should gate again.

The comments document WHY a workaround exists and point at the underlying issue — they are not stray TODOs that should be cleaned up. godox was flagging 50 such markers across cmd/apiserver, pkg/api/v1, pkg/drbd, pkg/luks, pkg/storage, pkg/store, pkg/uevent, pkg/rest, pkg/satellite, pkg/dispatcher, pkg/version, and tests/contract. Add a separate path-based exclusion rule per package that disables ONLY godox (every other linter still gates) so the bug-tracker markers don't fail CI while real godot/wrapcheck/etc. issues remain enforced.

charset=UTF-8 Content-Transfer-Encoding: 8bit Mixed-bag cleanup pass closing 44 of the remaining 87 lint findings. pkg/version: - gochecknoglobals: `//nolint` on the ldflags-injected Version / GitCommit / LinstorGitHash / LinstorBuildTime vars (standard pattern — `-ldflags -X` only works on vars). - godoclint: rewrite Project godoc to start with the symbol name. - wrapcheck: wrap os.ReadFile errors in bug_238_test.go with fmt.Errorf "%w". pkg/storage: - gocritic emptyStringTest: `len(attr) == 0` → `attr == ""`. - gosec G109: annotate volume-suffix Atoi→int32 conversions as bounded by the fixed `volNumberDigits=5` digit count. internal/controller: - gosec G115: annotate `len(diskful)→int32` as bounded by the in-memory slice cap. - gocritic whyNoLint: add reasons to the two `//nolint:nilerr` directives. - unparam: drop the always-nil error result from `placeCountForRD`. - goconst: extract `labelResourceDefinition` / `labelTrueValue` in autosnapshot_controller; reuse `drbd.DiskStateUpToDate` in resource_controller for the `UpToDate` literal (removes both occurrences). - mnd: extract `takenAllocsInitialCap` for the slice prealloc hint. - nestif: split `stampDeadline` / `stripDeadlineIfPresent` / `ensureRDPortMinor` retry path into focused helpers (`stampDeadlineViaCRD`, `stripDeadlineViaCRD`, `reloadCommittedPortMinor`) so each branch stays under the complexity budget. All changes are non-functional; unit tests stay green.

Closes 22 more findings across pkg/satellite, leaving 18 in the wider codebase. .golangci.yml exclusions: - unused/funlen: pkg/rest/peer_delete_sync.go (intentional Bug 342 v10 plumbing, not yet wired from the REST handler). - unused: pkg/satellite/reconciler_drbd_test.go (reserved sentinels for table-driven test growth). pkg/satellite/attach.go: - mnd: extract wipeZeroSpanMiB / wipeMinDeviceSizeForEndZeroMiB / mibBytes constants out of wipeDevice + readDeviceSizeMiB. - noinlineerr: hoist inline `err` assignments out of the `if` heads. - varnamelen: rename `sz` → `sizeBytes` in readDeviceSizeMiB. pkg/satellite/controllers: - snapshot_test.go staticcheck SA1019: drop deprecated `result.Requeue` reads — `result.IsZero()` is the modern equivalent that covers both the legacy `Requeue:true` shape and the `RequeueAfter>0` shape. - observer.go / resource.go varnamelen: rename `v` → `vol` / `p` → `peer` in two range loops where the short form spans more than the scope cap. - resource.go wrapcheck: wrap the Reader.Get error inside the retry-on-conflict closure with `cockroachdb/errors.Wrap`. pkg/satellite/peer_identity_cleanup.go: - revive unused-parameter: rename `vols` → `_` (signature shape kept for symmetry with the upstream call site). - nilnil: annotate the legitimate `(nil, nil)` no-op return with a reason — the caller treats a nil map as no-op on purpose. pkg/satellite/reconciler.go: - noinlineerr: lift the `detachIfStillAttached` inline assignment. pkg/satellite/reconciler_drbd_test.go: - prealloc: size `steadyCmds` with `len(commands) * len(cases)`. pkg/satellite/reconciler_internal_test.go, pkg/satellite/reconciler_locale_test.go: - revive error-strings / staticcheck ST1005 / err113: annotate the verbatim drbdadm / cryptsetup stderr fixtures with reasons; locale + capitalization fidelity is the entire point of these table rows.

Result: exec: "/manager": stat /manager: no such file or directory RunContainerError → e2e wait-for-ready timeout Found via the SSH breakpoint on PR #10's E2E failure. The previous fix in this PR (`docker-build --target controller`) put the right image in place; this completes the chain to make the container actually exec the binary that ships inside it.
