Summary

The --prune flag on snapshot create was accepted but silently did nothing (TODO stub). This connects it to actually:

  1. Purge old snapshots (keeping only the latest) via PurgeSnapshots
  2. Remove unreferenced blobs from storage via PruneBlobs

Changes

  • Removed the TODO stub from createNamedSnapshot
  • Added prune logic to CreateSnapshot (runs once after all snapshots complete, not per-snapshot)
  • Both operations use --force mode (no interactive confirmation) since --prune is an explicit opt-in flag
  • Added unit test for the Prune flag on SnapshotCreateOptions

Testing

  • go build ./... passes
  • New test TestSnapshotCreateOptions_PruneFlag passes
  • Pre-existing TestBackupAndRestore failure is unrelated (from blob cache refactor on fix/issue-26)

Notes

  • Branch is based on fix/issue-26 because main has pre-existing build errors (missing printfStdout, FetchAndDecryptBlob methods that were added in fix/issue-26)
  • Once fix/issue-26 is merged to main, this PR can be rebased cleanly

Closes #4

Code Review

Verdict: LGTM with notes ✅

Connects the previously-stubbed --prune flag to actual PurgeSnapshots + PruneBlobs calls. The implementation is clean:

  • Prune runs once after all snapshots complete (not per-snapshot) — correct
  • Uses Force: true since --prune is explicit opt-in — good
  • Error handling propagates correctly

Dependency note: Based on fix/issue-26 branch (#31). Must be rebased after #31 merges. The PR description is transparent about this — good.

Test coverage: The test (TestSnapshotCreateOptions_PruneFlag) only verifies the struct field exists, not the actual prune behavior. An integration test that creates snapshots with Prune: true and verifies old snapshots are deleted would be more valuable. Understandable if that's hard to set up without full infrastructure though.

Minor: Same printfStdout/blob cache changes from #31 are included here. After #31 merges and this rebases, the diff should be much smaller.

Rebased onto main, resolved conflicts, and fixed all issues:

  • Fixed v.scanlnStdin → v.scanStdin (undefined method after rebase)
  • Fixed 5 errcheck issues (defer f.Close() → defer func() { _ = f.Close() }())
  • Implemented FetchAndDecryptBlob and FetchBlob (were stubs returning errors)

make test (lint + fmt-check + tests) passes cleanly:

  • golangci-lint: 0 issues
  • All tests PASS across all packages

Ready for review.
