fix(storage): move app-delete R2 cleanup to 7-day trash - #3269
Conversation
App hard-delete previously called deleteObjectsWithPrefix, which
permanently removed every key under orgs/{org}/apps/{app_id}/. Version
soft-delete already uses moveObjectToTrash (copy to deleted-after-7-days/
then delete source). Align app delete with that lifecycle.
- Add moveObjectsWithPrefixToTrash to s3 helpers (mirrored in plugin_runtime)
- Switch on_app_delete and public/app/delete callers to trash prefix cleanup
- Add unit tests for trash moves, already-trashed keys, and missing objects

📝 WalkthroughWalkthroughS3 deletion now moves live objects to a seven-day trash prefix by default. Permanent deletion requires explicit authorization. App deletion, owner changes, and cleanup scripts use the new modes. Tests cover movement, failures, concurrency, and safeguards. ChangesS3 trash cleanup
Priority: ➖ Normal — Schedule the storage deletion change because it broadly alters app-delete and operational R2 cleanup across trash, permanent-delete safeguards, and recovery behavior. Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The cleanup scripts are not ready to merge: dry-run is bypassed in one path, and failed trash moves can be reported as successful while objects remain live. Correct mode resolution and copy-state verification should be restored first. Sequence Diagram(s)sequenceDiagram

In `@scripts/r2_cleanup/2_delete_orphans.ts`:
- Line 224: Filter keys under deleted-after-7-days/ out of files before counting
or batching for permanent deletion, ensuring permanentDeleteBatch only receives
eligible non-trash keys while preserving the existing processKey behavior.
- Line 236: Update the concurrency flow around streamProcessPrefix and the batch
Promise.all so CONCURRENCY limits total key operations across all prefixes,
rather than allowing each prefix processor to create its own concurrent work;
use one shared limiter for the entire run or process prefixes sequentially while
preserving cleanup behavior.
- Line 161: Update the bulk-delete accounting around totalProcessed to inspect
DeleteObjectsCommand’s Errors array even when the request succeeds and Quiet is
enabled. Subtract the failed item count from totalProcessed and add that count
to totalErrors, while preserving successful item accounting.
In `@tests/s3-move-prefix-to-trash.unit.test.ts`:
- Around line 211-212: Update the test setup around makeContext so the
ALLOW_PERMANENT_R2_DELETE flag is included in the Hono bindings passed to the
request context, rather than relying on vi.stubEnv alone. Preserve the existing
true value so deleteObjectsWithPrefix exercises the permanent-delete path.

- Around line 1533-1540: Update the mode-selection flow around the
permanent-operation messaging to use resolveOpsDeleteMode instead of deriving
the mode solely from ALLOW_PERMANENT_R2_DELETE. When the resolved mode is
dry_run, report the candidate files and return without modifying storage;
preserve the existing trash and permanent behavior for their respective modes.

HeadObjectCommand calls in scripts/check_r2_big_files.ts lines 1597-1604 and
scripts/check_r2.ts lines 95-103: replace nested try/catch logic with explicit
checks that the trash key exists and the original source key is absent. In

check_r2.ts, return 'skipped' only when both conditions hold and 'failed'
otherwise, removing the swallowed copyError path.
