Description

☝️ While possibly flaky before, this issue has become MUCH more prominent since updating to Windows 2025

This test is failing frequently (50%) on Windows;

=== FAIL: github.com/docker/docker/integration/container TestExecResize/success (0.01s)
    exec_test.go:144: assertion failed: error is not nil: Error response from daemon: NotFound: exec: '9c19c467436132df24d8b606b0c462b1110dacfbbd13b63e5b42579eda76d7fc' in task: '7d1f371218285a0c653ae77024a1ab3f5d61a5d097c651ddf7df97364fafb454' not found: not found

The failure happens after the exec was created, and started https://github.com/moby/moby/blob/1d272a430d788cc55505965a354d3ea81987bd4c/integration/container/exec_test.go#L139-L151

The confusing part here is that ContainerExecStart should return a "not found" error if the ExecID doesn't exist https://github.com/moby/moby/blob/79f802d46a6087aaec68755de04b5cb7348858a9/daemon/server/router/container/exec.go#L86-L88

That does NOT happen, so there looks to be a discrepancy between dockerd considering the exec to exist, but containerd (or the underlying runtime (hcsshim ?)) to not consider it to exist.

The exec: 'XXX' in task: 'YYY' not found: not found appears to be coming from containerd; possibly the process is not running, and the error coming from here; https://github.com/moby/moby/blob/2837112c8ead55cdad36eaac61bafc713b4f669a/daemon/resize.go#L57

With the "local" libcontainerd, we'd hit this; https://github.com/moby/moby/blob/3ee8c1e3a9d7f2b74e69471251f31221191a6aff/daemon/internal/libcontainerd/local/local_windows.go#L745-L761

With containerd, it'd come back from the client here, but I'd have to try find the implementation in containerd; https://github.com/moby/moby/blob/0aa8fe0bf949cbccab74414cb091728854be0d7d/vendor/github.com/containerd/containerd/v2/client/process.go#L51-L52

Which probably hits this; https://github.com/containerd/containerd/blob/release/1.7/services/tasks/local.go#L743-L753

Running the test in a loop (with the other PR's patch applied), we hit the problem 50% of the time, but sometimes with different errors; either the execID to not be running, or it not being found;

run (graphdriver) / integration-test (graphdriver, containerd, ./...) is failing ~ 45% of the time, but 2 different cases;

  • 40 x exec_test.go:154: timeout hit after 10s: waiting for exec XXX to be running
  • 5 x exec_test.go:171: assertion failed: error is not nil: Error response from daemon: NotFound: exec: 'XXX' in task: 'YYY' not found: not found

Research direction

Start with integration/container/exec_test.go at the referenced lines and reproduce the failures using the run (graphdriver) / integration-test (graphdriver, containerd, ./...) loop. Trace resize handling through daemon/resize.go, daemon/internal/libcontainerd/local/local_windows.go, and the containerd client process.go path. Done means TestExecResize and TestExecResizeStress no longer fail intermittently on Windows and resize reports the expected result.
