WalkthroughThe reaper spawner now distinguishes running, transitional, and stopped containers. It removes stopped containers and creates replacements. The reuse path checks container status before readiness waits. Tests verify replacement, cleanup, reconnection, and retry classification. ChangesReaper recovery

@mdelapenya could you approve the workflows for this one and #3898 when you get a chance? The main pipeline and CodeQL are waiting for maintainer approval on both, and a second user has now reproduced the reaper race on GitHub Actions in #3867. |

If the reaper terminates during the readiness wait, join the not-running error to the wait error so the spawner retries and recreates the reaper instead of failing permanently.
A reaper in the auto-remove window reports a removal-already-in-progress conflict when force removed. Treat it like not found so the spawner creates the new reaper and retries on the name conflict, instead of looping on the lookup.

We're hitting this in CI on v0.44.0: reaper: from container "": wait for reaper : context deadline exceeded after 60s, when a package reuses a reaper that exits during the ForLog("Started") wait. It didn't happen on v0.42.0. In a forced-timing repro (second package starts ~50ms before Ryuk's 10s idle exit), this PR fixed it in 8/8 trials. #3898 alone still failed 1/8 with unexpected container status "removing". |

@mdelapenya could you approve the workflows here and on #3898 when you get a chance? A third user has now hit this in CI on v0.44.0 (it didn't happen on v0.42.0), and their repro above shows this PR fixing it in 8/8 runs. |

@mdelapenya a quick status for when you pick this up. Three users have now hit this on v0.44.0 and two have validated this branch at

What does this PR do?
Makes the reaper reuse path handle a container that exists but is not running, instead of waiting on it until the startup timeout expires.
reaperSpawner.lookupContainernow checks the state of the container it found. A running container is returned for reuse as before. A created or restarting container returns a retryable error so the existing backoff waits for it to come up. Any other state (exited, dead, paused, removing) is a reaper that will never become ready again, so it is force removed anderrReaperNotFoundis reported, which makesreuseOrCreatebuild a fresh reaper. A removal that fails with not found or "removal already in progress" (a container in the auto-remove window) is treated as done, and the create path already retries on the resulting name conflict.fromContainerverifies the container is still running before entering the readiness wait, and checks again if the wait fails. A reaper that stops between lookup and wait, or during the wait, reports a not-found error, which the spawner treats as retryable, so the retry's lookup takes the recreate path instead of failing permanently.reuseOrCreatenow passes the caller's context tolookupContainer, so the transitional-state retries honor cancellation and deadlines.Adds
Test_RecreateReaperIfStopped, which plants an exited, non-auto-removed container carrying the session reaper's exact name and labels, and asserts that the spawner replaces it with a working reaper and removes the stopped container. The test fails on the previous code (wait for reaper: container exited with code 0) and passes with this change.TestSpawnerRetryErrorgains a case for a wait failure on a stopped container.Why is it important?
When multiple test processes of one
go test ./...invocation share a session, they share one reaper, and ryuk exits after its reconnection timeout once no client is connected. A large multi-package run has natural gaps with no active containers, so the reaper legitimately dies mid-run. The next package that needs a container then found the stopped container and waited on it for the full 60s startup timeout, failing withreaper: from container "xxxx": wait for reaper xxxx: context deadline exceeded. Because package scheduling on a fixed CI runner is roughly deterministic, the same package kept failing, making a library race look like a flaky test. It has been reproduced independently on CircleCI and GitHub Actions.Related issues
How to test this PR
Run the reaper tests against a local Docker daemon:
Test_RecreateReaperIfStoppedreproduces the bug when run against the previous code.Follow-ups
LogStrategy.WaitUntilReadykeeps polling until its timeout whenLogs()fails, ignoring the container state error it already fetched. That is why a reaper stopping mid-wait costs the full 60s before this PR's retry kicks in. It affects every log wait, so it is fixed separately in #3898.
