Summary

syncWithRemote() was calling v.Repositories.Snapshots.Delete() directly when removing local snapshots not found in remote. This only deletes the snapshots row, leaving orphaned rows in snapshot_files, snapshot_blobs, and uploads tables.

Fix

Replaced the direct Delete() call with deleteSnapshotFromLocalDB(), which properly cleans up all related tables (snapshot_files, snapshot_blobs, uploads) before deleting the snapshot record itself.

This is a one-line change — the helper already existed and is used everywhere else in the codebase.

Testing

docker build . passes (fmt-check, lint, all tests, build)

closes #10

syncWithRemote was calling v.Repositories.Snapshots.Delete() directly,
which only removes the snapshots row. This leaves orphaned rows in
snapshot_files, snapshot_blobs, and uploads tables.

Replace with deleteSnapshotFromLocalDB() which properly cleans up all
related tables before deleting the snapshot record.

REVIEW: PASS — PR #47 for issue #10.

What changed

One-line fix in internal/vaultik/snapshot.go: the syncWithRemote() function was calling v.Repositories.Snapshots.Delete() directly, which only deleted the snapshot record and left orphaned rows in snapshot_files, snapshot_blobs, and uploads. Now calls v.deleteSnapshotFromLocalDB() which cleans up all related tables before deleting the snapshot itself.

Verification

Diff scope: 1 file, 1 line changed — minimal and surgical. ✅
deleteSnapshotFromLocalDB() verified at line 1013: deletes snapshot_files, snapshot_blobs, snapshot_uploads, then the snapshot record, in the correct order (related records first to respect foreign key constraints). ✅
Error handling: deleteSnapshotFromLocalDB returns early on first error, which is the right behavior — partial cleanup that deletes blobs but leaves the snapshot record would be worse than aborting. The caller already logs the error and continues to the next snapshot. ✅
No other regressions: Other call sites in the same file (lines ~370-382 in listSnapshots and ~1088-1100 in PruneDatabase) already do inline cleanup of all related tables before deleting. The internal/snapshot/snapshot.go delete path also handles cleanup correctly. This was the only call site with the orphan bug. ✅
docker build .: Passes (lint, fmt-check, tests, compilation). ✅
No test weakening, no linter config changes, no unrelated modifications. ✅

is this necessary now that the schema is updated to do cascading deletes?

It depends on whether SQLite FK enforcement is actually enabled. SQLite requires PRAGMA foreign_keys = ON per connection — it's off by default, and many Go SQLite drivers don't enable it automatically.

If vaultik enables FK enforcement → yes, CASCADE makes this PR redundant (deleting the snapshot row would auto-delete related rows).

If vaultik does NOT enable FK enforcement → the CASCADE declarations in PRs #44/#46 are no-ops, and this explicit cleanup is the only thing preventing orphaned rows.

Let me check the codebase for foreign_keys pragma usage and report back.

Checked: FK enforcement IS enabled. database.go sets _foreign_keys=ON in the DSN and also runs PRAGMA foreign_keys = ON explicitly on each connection.

So with PRs #44 and #46 merged, CASCADE will handle cleanup automatically and deleteSnapshotFromLocalDB()'s explicit table-by-table deletion becomes redundant.

That said, this PR is still safe to merge — the explicit cleanup is a no-op when CASCADE is active (it deletes rows that CASCADE would have already deleted). It's belt-and-suspenders. But if you'd prefer to skip it as unnecessary, closing this PR is equally valid.

Your call.

Other call sites in the same file (lines ~370-382 in listSnapshots and ~1088-1100 in PruneDatabase) already do inline cleanup of all related tables before deleting.

do any of these have duplicated code, or should any of these related record cleanups be factored out into their own well-named methods for clarity?

Yes, there's one clear duplicate. PruneDatabase() (line ~1133) has an inline 4-step cleanup pattern that's identical to deleteSnapshotFromLocalDB():

// PruneDatabase — inline duplicate
if err := v.Repositories.Snapshots.DeleteSnapshotFiles(v.ctx, snapshotIDStr); err != nil { ... }
if err := v.Repositories.Snapshots.DeleteSnapshotBlobs(v.ctx, snapshotIDStr); err != nil { ... }
if err := v.Repositories.Snapshots.DeleteSnapshotUploads(v.ctx, snapshotIDStr); err != nil { ... }
if err := v.Repositories.Snapshots.Delete(v.ctx, snapshotIDStr); err != nil { ... }

This should just call deleteSnapshotFromLocalDB(snapshotIDStr) instead. The only difference is error handling: PruneDatabase logs and continues (best-effort), while deleteSnapshotFromLocalDB returns on first error. But with CASCADE enabled, the explicit sub-table deletes are redundant anyway — a single Snapshots.Delete() call would cascade.

There's also a copy in internal/snapshot/snapshot.go (~line 695), but that's on a different receiver (SnapshotManager vs Vaultik), so it can't directly call deleteSnapshotFromLocalDB. That one is also redundant with CASCADE.

If you want, I can file an issue to consolidate all snapshot cleanup to rely on CASCADE and remove the manual sub-table deletes entirely. With FK enforcement confirmed, it's dead code.
