What this PR does

Reported in #3737.

Both OIDC suites asserted things that are already true a few seconds after the tenant Kubernetes CR is applied, and then ended while the release was still installing. The kind sets helm-install-disable-wait, so the install skips the in-tenant addon HelmReleases, but it still waits for the chart's two blocking post-install hook Jobs, and one of them polls for the Kamaji-issued admin kubeconfig first. Helm cannot uninstall a release whose install action is running, so the rest of the install landed in the cleanup phase on top of the teardown, against one 5m budget. Both suites could go red on a cleanup step that asserts nothing, seconds after every assertion had passed.

Each suite now waits on its last step: HelmRelease at Ready, then the OIDC bootstrap Job at status.succeeded. The Job assert is a read rather than a wait, since a release cannot be Ready while a blocking hook Job is still running. It also covers something neither suite checked before: that Job writes the per-user ClusterRoleBindings inside the tenant and patches the OIDC kubeconfig Secret.

The two budgets differ on purpose. System waits 20m, bounded below by a worst-case backoff on the other hook Job's token Secret mount, and above by the kind's own helm-install-timeout, past which helm-controller abandons the install and a longer wait cannot see a success that is no longer coming. CustomConfig keeps 5m, which covers the common case but not the worst one. Making them equal adds another 20m wait to the most expensive failure path either suite has, and the room for that has to come from bounding the collectors under it first.

What it costs: a failing suite is now much slower, because a failure in try runs the catch handlers and a cleanup overrun did not. Every catch op in both suites carries an explicit timeout, so that cost is a number someone picked.

Two things ride along.

  • hack/chainsaw-tenant-cluster-cleanup.bats holds future fixtures to the same rule. It finds every Chainsaw Test that applies a Kubernetes CR through apply.file and requires both asserts on the last step, by name and by field, in that order, with both budgets positive and the Job's shorter than the Ready wait and under an absolute ceiling. The ceiling earns its place next to the comparison: a relative bound loses its grip as the Ready budget grows, and raising a wait should not widen what can hide underneath it.
  • Both fixtures claimed that an empty nodeGroups install produces no workers. The MachineDeployment does render with replicas: 0, but the chart's own cluster-autoscaler then scales the default group to one worker, because the in-tenant addon Pods have nowhere to schedule. The comments are corrected here, one in a helm-unittest case too. The behaviour itself is e2e: the OIDC fixtures each provision a worker VM they claim not to, with no drain barrier #3739 and is left alone.

This does not bound the teardown, which is the larger of the two terms sharing that budget. Taking the install remainder out is what puts the run in #3737 under 300s, but a slow enough teardown still crosses it on its own, and that bound belongs to the chart rather than to an e2e test. For kubernetes-oidc-customconfig the teardown has no measured upper bound at all, which is #3801.

Screenshots

No UI changes.

Downstream repositories

Walked the map against the diff, file by file. It is e2e fixtures, their conventions doc, one new hack/*.bats unit test, and comments in a helm-unittest case. Nothing under hack/ is moved or renamed, hack/package.mk, hack/common-envs.mk and hack/update-crd.sh are untouched, and no make target changes: bats-unit-tests already globs hack/*.bats, so the recipe stays as it is. No package is added, renamed or removed, no values.yaml, values.schema.json, version enum or ApplicationDefinition is touched, and hack/e2e-prepare-cluster.bats is not in the diff. Nothing on the map fires.

Release note

fix(e2e): the OIDC Chainsaw suites wait for the tenant cluster release to finish installing before they end, so the leftover install is no longer charged to the cleanup budget and reported as a failure of a step that asserts nothing. A unit guard holds new tenant-cluster fixtures to the same rule.

Merge Risk: 🔵 Low · up to 3b1d9

The change makes OIDC end-to-end tests wait for installation completion, but the accompanying fixture guard can misdiagnose unreadable release metadata and silently miss fixtures using the .yml extension. The PR is mergeable with explicit owner awareness and follow-up to harden the guard.

Include *.yml manifests in the walk.

_tenant_cluster_manifests globs *.yaml only. A manifest named <name>.yml is invisible to the forward walk and to _tenant_cluster_manifests_all, so a fixture that applies its tenant Kubernetes CR from a .yml file passes both directions silently. That is a third escape hatch, and the header at lines 92-104 documents only two.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Reject an unreadable release.prefix instead of building an expectation from it.

_release_prefix discards stderr and returns an empty string when $KUBERNETES_RD is missing, and the literal null when the field is renamed. Both values still produce a release name, so the guard compares the fixtures against a name that does not exist. _synth_suite derives its own name from the same helper at line 455, so the synthetic baseline stays green and the failure surfaces only on the real fixtures, with a message that blames the fixture's assert.

Fail on the prefix itself so the diagnosis names the ApplicationDefinition.

mikefarah yq version added greater than comparison operator and null operand behavior

💡 Result:

In mikefarah/yq, the greater than (>) comparison operator is used to compare scalar values of the same type, specifically numbers, strings, and datetimes [1]. Regarding null operand behavior in comparisons: - If both sides of a greater than (>) comparison are null, the result is false [1][2]. - If both sides of a greater than or equal to (>=) comparison are null, the result is true [1][2]. The behavior for these comparison operators with nulls is documented in the official yq documentation [1]. While specific release notes mention various null-related fixes (e.g., in sort_by expressions or JSON to TOML handling) [3][4], the core null comparison behavior for relational operators is a foundational part of the yq (v4+) comparison logic [1][2].

site:mikefarah.gitbook.io/yq/operators/compare yq v4 comparison null number missing field greater than

💡 Result:

In yq v4, comparison operators (>, >=, <, <=) are designed to compare scalar values of the same type, specifically numbers, strings, and datetimes [1]. When performing comparisons, yq treats missing fields and null values similarly in that they do not contain a comparable scalar value. If a field is missing, it evaluates as null [1]. The behavior for null values in comparisons is as follows [1]: - The greater than (>) operator returns false when both sides are null [1]. - The greater than or equal to (>=) operator returns true when both sides are null [1]. Because a missing field is treated as null, these same rules apply. If you need to differentiate between a missing field and an existing null value, you must explicitly check for field existence using operators like has before performing a numeric or string comparison [1]. Example of null comparison behavior: yq --null-input '.a >.b' # Returns false [1] yq --null-input '.a >=.b' # Returns true [1]

mikefarah yq compare operator source null different type comparison error github

💡 Result:

In mikefarah/yq, comparison operators (>, >=, <, <=) are designed to compare scalar values of the same type [1][2]. The officially supported types for these comparisons are numbers, strings, and datetimes [1][3]. When you attempt to compare different types or include null values in these comparisons, yq often produces a "not yet supported for comparison" error [4]. Specifically, the comparison logic requires that both sides of the operator resolve to compatible types [1][2]. Regarding null handling: - Explicit null comparisons: The documentation notes that if both sides are null, the > operator returns false and the >= operator returns true [1][3]. - Error behavior: If one side is a null value and the other is a different type (or if the types are otherwise incompatible), yq will typically throw an error, such as "!![type] not yet supported for comparison" [4]. - Historical context: Some issues related to null comparisons and type mismatches have been addressed in past updates (e.g., issue #1427 fixed issues where length comparisons to null were failing, and issue #1537 improved consistency for datetime comparisons) [5][6][4]. If you are encountering a "different type comparison" error, ensure that both values being compared are of the same type. You can often enforce types by using operators like from_yaml or by casting values to ensure consistency before performing the comparison [4]. Top results: [1][2][4]

Fix itself is right and you measured it, that part I have no argument with. Install remainder does move out of cleanup, cleanup went from a 233s median to 187s in your own run, and the pass path costs about 20 seconds. It also finally puts a number on #3801.

What I am blocking on is the 20m budget against the job cap.

E2E (in-tree) has timeout-minutes: 180 (pull-requests.yaml:721). The run on this PR, 31808894413, took 172m39s wall clock. That is 7m21s of headroom and the new assert alone is 20m. It is not a tail case either: with Install.Strategy RetryOnFailure and no retry cap the HelmRelease never reaches Ready on a real install failure, so the assert runs to its ceiling every time, which the fixture itself states. Crossing 180 does not give a red suite with diagnostics, the job ends cancelled and per .chainsaw.yaml:65 the grace window goes to Collect report, so cozyreport.tgz and the job log are both lost. A step written to make a failure readable produces a run with nothing left to read.

The envelope the fixture cites (127/131/138m) is stale by about half an hour, I checked 31582632048 at 152m and this one at 172m39s.

Second thing, about shape rather than correctness. 971 lines to police two fixtures. The guard works, I mutated it eight ways including an empty discovery set and it fails closed, so this is not about trust. But chainsaw 0.2.15 has steps[].use.template, and a shared step fragment in _lib/ that both fixtures include makes the rule structural instead of policed after the fact. You cannot write the step wrong if you do not write the step. It also closes the .yml and nested directory holes by construction rather than by documenting them, around 30 lines instead of 971.

20m here against timeout-minutes: 180 on the e2e job, and this PR's own run was 172m39s, so headroom is 7m21s. On a real install failure this assert reaches its ceiling every time because the release retries forever, and crossing the job cap loses cozyreport.tgz and the log both. Either land #3754 first so the headroom exists, or take the per Test timeouts: {cleanup: 10m} lever you already considered and rejected, which costs nothing on either path and lets this drop to 8-10m without reding a legitimately slow install. Do not just lower the number on its own, the 15m floor from bootstrap-token-tenant-job.yaml:41-48 is real.

Glob is *.yaml here and */chainsaw-test.yaml at 258, so a fixture named .yml or sitting one directory deeper is invisible to discovery and every test stays green. I checked both, renamed a fixture to .yml and nested another one with no asserts at all, six tests green in both cases. The doc says "two shapes are outside the guard's reach", which reads as the full list. *.y*ml and either recursion or a stated flat directory assumption.

Followup on the 180m point, it is not a projection any more. #3804's E2E (in-tree) on run 31796831760 ran 11:55:31 to 14:55:41, which is 180m10s, and ended cancelled. That is not a test failure, the job hit timeout-minutes: 180 and was killed. #3804 is approved and this is the only thing blocking it.

So the headroom I quoted is already spent on a PR that adds no new wait at all. That is what I am asking you to weigh the 20m assert against. The per Test timeouts: {cleanup: 10m} lever still looks like the cheapest way to get the same protection without spending it.

Correction to my own review, and the blocking half of it does not hold.

I said crossing timeout-minutes: 180 loses cozyreport.tgz and the job log. That is wrong, and I should have read the step list before writing it. On run 31796831760 the attempt that was cancelled at 180m10s had already uploaded cozyreport at 14:34:27, twenty one minutes before the cancel, and the artifact is still there at 49MB. What consumed those last twenty one minutes was Breakpoint on E2E failure, which opens on a maintainer-authored red run and holds up to thirty minutes. The rerun behaved the same way and finished clean: tests failed at 00:02:40, report collected and uploaded by 00:03:30, breakpoint held 20m06s, job completed.

So the real shape is that the effective budget for the test phase is about 150m rather than 180m, because the tail is reserved for a debug pause, and crossing the cap costs that pause rather than the evidence. Your 20m assert still spends a real number and I would still rather it were smaller, but that is a request and not a block, so I am dismissing the blocking half.

The rest of my review stands unchanged. 971 lines to police two fixtures is the part I would still like reconsidered, since steps[].use.template makes the rule structural instead of policed after the fact, and closes the .yml and nested-directory holes by construction rather than by documenting them.

Withdrawing the blocking half. The 180m ceiling does not lose the artifacts, reasoning in the comment below. The guard-size point is a request, not a block.

Both OIDC suites asserted render-side facts that hold a few seconds
after the tenant Kubernetes CR is applied, and then ended. The install
action for that release was still running at that point: the kind sets
helm-install-disable-wait, so the install does not wait for the
in-tenant addon HelmReleases, but it does still wait for the chart's
two blocking post-install hook Jobs, and one of them polls for the
Kamaji-issued admin kubeconfig before writing the tenant
ClusterRoleBindings.

A Helm release cannot be uninstalled while its install action is
running, so ending the test there handed the remainder of the install
to the cleanup phase on top of the teardown itself, against a single
five-minute budget. Both suites were reported red on a cleanup step
that tests nothing, seconds after every assertion had passed.

Wait for the release on the last step instead: HelmRelease at Ready,
then the OIDC bootstrap Job at status.succeeded. The ordering is what
makes the second assert cheap -- a release cannot be Ready while a
blocking hook Job is still running, so by then the Job is settled and
reading it costs a poll. Asserting it also closes real missing
coverage: that Job applies the per-user ClusterRoleBindings inside the
tenant and patches the OIDC kubeconfig Secret, and neither suite
checked that it ran.

The two suites get different budgets deliberately. The System suite
waits 20m, bounded on both sides by the install path rather than by a
CI budget: below by a worst-case backoff on the other hook Job's
non-optional token Secret mount, above by the kind's own
helm-install-timeout, past which helm-controller abandons the install
so a longer wait cannot observe a success that is no longer coming.
The CustomConfig suite keeps a 5m wait, which removes the common case
but not the worst one; matching them would add another copy of the
same wait to a failure path that is already the most expensive thing
either suite contributes, and the room has to come from bounding the
collectors underneath it first.

Note what this costs: a failing suite is now considerably more
expensive than it was, because a failure in try runs catch handlers
and a cleanup overrun did not. Every catch op in both suites carries
an explicit timeout so that cost is a stated number rather than an
inherited one, and the reds being replaced were false ones while a red
that now costs the full wait means the install genuinely did not
finish.

State the rule in the e2e conventions, where the list of justified
longer waits also gains the System suite's 20m, with the caveat that
nothing checks that list and it therefore records cases rather than a
maximum. Add a unit guard holding future fixtures to the rule, written
to POSIX sh because cozytest.sh sources it under /bin/sh, which is
dash on the runner and bash on a workstation. It discovers every
Chainsaw Test that applies a Kubernetes CR through apply.file and
requires both asserts on the last step, by name and by field, in that
order, with both budgets positive and the Job's both shorter than the
Ready wait and under an absolute ceiling. That ceiling is not
redundant with the comparison: a relative bound loses its grip as the
value it refers to grows, and raising a wait must not widen what may
hide beneath it.

Correct a claim both fixtures carried about an empty nodeGroups
install producing no workers. The MachineDeployment does render with
replicas: 0, but the chart's cluster-autoscaler then scales the
default group to one worker in response to unschedulable in-tenant
addon Pods, and CI events carry the whole chain. A helm-unittest
comment describing the same case as render-side is corrected too,
since waiting for the install is what stops that being true.

This removes the term that was crossing the budget, which is not the
larger of the two. On the run these numbers come from, the install
remainder billed to cleanup was 57-117s while the teardown itself was
137-197s of the same 254s: taking the smaller term out is what brings
the total under the 300s budget, and the bigger half is left
unbounded. So a slow enough teardown can still cross that budget on
its own, and that bound belongs to the chart rather than to an e2e
test.
