fix(hack): compare release-watch keys per struct, in both directions - #70
Merged
Conversation
kube_keys flattened every toml key reachable from a Kubernetes* root into one set of names, so a name counted as exposed everywhere once it was exposed anywhere. That produced a wrong answer during #58: the watcher reported zero unexposed keys while selinux_type, seccomp_profile and app_armor_profile were missing from the container security context and mount_propagation was missing from empty_dir and pvc. All four names existed elsewhere in the file. Keys are now emitted as Struct.key, which puts the count at 253 upstream pairs against 241 here, where the flat name count was 200. The comparison also ran one way only, so a key we carry that upstream deleted was invisible. terminationGracePeriodSeconds has had no effect since gitlab-runner v17.0.0 and the watcher never mentioned it; it now appears under its own heading. #62 tracks the field itself. Both of those directions recompute the whole backlog on every release, so deliberate omissions would repeat forever. hack/runner-release-watch.suppress carries them as data the script reads rather than prose in a Go comment: the thirteen autoscaler pairs #58 decided against. The body reports how many were excluded and names any entry that matched nothing, so the exclusion stays visible and a stale line surfaces rather than quietly widening. The upstream-against-itself delta is deliberately not filtered; a key added to a skipped subtree is still a real change, and it is reported once rather than every release. The body also states which comparison it performed. "Nothing unexposed" is worth very little without that, and the flat-name version read as a proof it was not.

A directory is readable, so it passed the -r check and fell through to the parse. The failure was quieter than a plain read error: BSD sed exits 0 when handed a directory, so the parse yielded an empty list and the issue body stated that an exclusion file exists with zero exclusions. GNU sed exits 4 there, which the `|| true` on the pipeline swallowed to the same effect. Require a regular readable file, which is the part that holds on both platforms, and stop discarding sed's exit status so a genuine read error on a regular file is not read as "no exclusions" either.

) * docs(api): document that terminationGracePeriodSeconds does nothing Upstream removed the key at the v17.0.0 major boundary. The runner decodes with toml.DecodeFile and never inspects MetaData.Undecoded(), so a value set here is accepted by admission, rendered into config.toml, and then dropped with no error, no warning and no log line. The mitigation the issue credits does not exist on any user-facing surface. controller-gen only turns Go doc comments into the CRD description; the go-flags `description:` tag is invisible, so the deprecation text this field has carried since v16.11.0 never reached kubectl explain. Same finding as #71. All three fields here gain their first real description. Both replacements carried the same fossil, "Ignored if KUBERNETES_TERMINATIONGRACEPERIODSECONDS is specified", pointing at a key that no longer exists. Dropped from the tags rather than contradicted in a comment next to them. The v17.0.0 removal also moved a default. At v16.11.0 GetPodTerminationGracePeriodSeconds returned 0 when both keys were unset, which upstream commented as deliberate ("terminate immediately"). That getter went with the field, so the executor now passes the raw pointer to the pod spec and unset means Kubernetes' 30s. A runner upgraded across the boundary waits 30s where it used to exit at once, which is the fact a reader of pod_termination_grace_period_seconds most needs. Not removing the field. kubectl has defaulted to fieldValidation=Strict since 1.25, so dropping it from the CRD fails `kubectl apply` for any manifest that still sets it. That belongs in a release documenting the break, so the key is excluded from the release watcher's stale report instead, which #70 made bidirectional. The exclusion is counted in every release issue body and the watcher flags it as unused once the field goes, so it cannot rot silently. Refs: #62 Refs: #70 Signed-off-by: Alexander Chernov <alexander@chernov.it> * docs(api): add the missing space before DEPRECATED in the tag The description read "kill signal.DEPRECATED:", running two sentences together. Tidied while the neighbouring tags are being edited in this branch anyway. Note this is cosmetic only. CodeRabbit flagged it as breaking generated help text, which does not apply here: nothing in the operator parses go-flags tags and controller-gen ignores them, so the string never reaches a user. Regenerating the CRDs after this change produces no diff, which is the same point the rest of the branch makes.

hack/runner-release-watch.shcompared upstream's Kubernetes executor toml keys against ours as a flat, one-directional set of key names with no exclusion list. All three defects from #63 come from that one shape.Per-struct pairs. The awk extractor now emits
Struct.keyrather than a bare name, so a name being exposed on one struct no longer counts as exposed on every struct. Against the real files that is 253 upstream pairs versus 241 here, where the flat name count was 200.Exclusions as data.
hack/runner-release-watch.suppressholds the thirteen autoscaler pairs #58 decided against, parsed and shape-validated at startup so a typo stops the run instead of silently excluding nothing. The issue body reports how many were applied and names any entry that matched nothing, so a stale line surfaces rather than quietly widening the blind spot. An absent file is stated, not treated as empty. Only the two exposure directions are filtered: they recompute the whole backlog every release, whereas the upstream-against-itself delta reports a key added to a skipped subtree once, which is still a real change worth seeing.Both directions. Ours-minus-upstream gets its own heading. On live data it flags exactly one pair,
KubernetesConfig.terminationGracePeriodSeconds, which is #62 and which the watcher has never mentioned in its life.The body also states which comparison it performed, with both counts. "Nothing unexposed" is worth very little without that, and the flat-name version read as a completeness proof it was not.
Dry run against the current upstream release:
Six new cases (3b to 3f) cover the per-struct gap a flat set cannot see, exclusion in both directions, an exclusion that matched nothing, a malformed entry refusing before it files, and an absent file. 97 pass. Audited by reverting only the script against the new tests: 17 failures, all in the new cases plus the four existing assertions retightened to the qualified form.
Closes #63
