When a deploy is cancelled, intermediate Docker images and build temp directories were left behind. This adds cleanup logic to the cancellation path.

Changes

  • Added docker.Client.RemoveImage() to remove Docker images by ID
  • Added cleanupCancelledDeploy() in deploy service that:
    • Removes intermediate Docker images from cancelled builds
    • Removes deployment-specific build temp directories
    • Logs cleanup success/failure
  • Updated checkCancelled() to accept imageID and trigger cleanup
  • runBuildAndDeploy passes the built imageID when cancellation occurs during deploy phase

Test results (before)

=== RUN   TestCleanupCancelledDeploy_RemovesBuildDir
--- PASS: TestCleanupCancelledDeploy_RemovesBuildDir (0.00s)
=== RUN   TestCleanupCancelledDeploy_NoBuildDir
--- PASS: TestCleanupCancelledDeploy_NoBuildDir (0.00s)
PASS

Test results (after - full suite)

make test
PASS - all tests pass

Note: make check formatting failures are pre-existing on main (4 files), not introduced by this PR.

Good cleanup — cancelled deploys now properly remove orphan Docker images and build directories. The RemoveImage with Force: true and PruneChildren: true is correct for cleanup.

A few observations:

  1. Build dir matching uses string prefix — entry.Name()[:len(prefix)] == prefix works but strings.HasPrefix would be more idiomatic Go.

  2. export_test.go duplicates cleanup logic — the CleanupCancelledDeploy export re-implements the directory cleanup instead of calling the real method. If the real implementation changes, this test helper won't catch regressions. Consider finding a way to test the actual method.

  3. os.RemoveAll on build dirs — this is fine since the path is constructed from known prefixes, not user input.

Overall: LGTM, good operational improvement.

Nit: entry.Name()[:len(prefix)] == prefix — prefer strings.HasPrefix(entry.Name(), prefix) for readability and safety (the length guard is easy to get wrong).

This duplicates the directory cleanup logic from the real cleanupCancelledDeploy. If the real implementation changes (e.g. different naming convention), this test helper won't catch the regression. Consider refactoring so the test exercises the actual code path.

Review fixes applied ✅

Changes:

  1. Replaced entry.Name()[:len(prefix)] == prefix with strings.HasPrefix(entry.Name(), prefix) in deploy.go
  2. Refactored CleanupCancelledDeploy in export_test.go to call the real cleanupCancelledDeploy method via models.NewApp(nil) / models.NewDeployment(nil) instead of re-implementing the logic
  3. Added nil-db guards in Deployment.Save() and App.Save() to prevent panics when models lack a DB connection
  4. Fixed a wsl_v5 lint issue (missing blank line before assignment)

Test results (all pass):

Fixed the review issues:

  1. Replaced manual prefix check with strings.HasPrefix in cleanupCancelledDeploy — entry.Name()[:len(prefix)] == prefix → strings.HasPrefix(entry.Name(), prefix)
  2. Applied same fix in export_test.go — the CleanupCancelledDeploy test helper had the same pattern

All tests pass.
