Metadata

  • Branch: fix/flaky-tests-worker-tool-failures
  • Commit Message: fix(test-infra): resolve worker tool failures blocking flaky-tests analysis
  • Milestone: v3.2.0
  • Parent Epic: #1706

Description

The worker assigned to the flaky-tests analysis area is unable to proceed due to consistent tool failures.

Affected Tools:

  • bash: Fails with ENOENT: no such file or directory, posix_spawn '/bin/zsh'
  • glob: Fails with Maximum call stack size exceeded.
  • read: Fails with Maximum call stack size exceeded.

Impact:
The worker cannot access the cloned repository's filesystem, preventing any analysis of the code, CI configuration, or test suites. This completely blocks the flaky-tests analysis (see #1706).

Steps to Reproduce:

  1. Start a ca-test-infra-improver worker with focus_area: flaky-tests.
  2. The worker successfully clones the repository.
  3. The worker attempts to use bash, glob, or read to access the cloned repository.
  4. The tools fail with the errors mentioned above.

Subtasks

  • Investigate the worker environment to determine why /bin/zsh is unavailable for bash tool execution
  • Investigate the glob and read tool implementations to identify the cause of Maximum call stack size exceeded errors
  • Reproduce the failures in a controlled environment
  • Implement a fix for the bash tool (e.g., fall back to /bin/sh or ensure /bin/zsh is present)
  • Implement a fix for the glob and read tools to prevent stack overflow
  • Verify the ca-test-infra-improver worker can successfully access the cloned repository after the fix
  • Add a regression test or environment health check to detect tool failures early

Definition of Done

  • bash tool executes successfully within the worker environment
  • glob tool returns results without stack overflow errors
  • read tool returns file contents without stack overflow errors
  • A ca-test-infra-improver worker with focus_area: flaky-tests can complete its analysis end-to-end
  • Root cause is documented in the issue or a follow-up comment
  • All nox stages pass
  • Coverage >= 97%
