Three pre-existing bugs surfaced by re-running the backup-s3 integration
suite. backup-s3 went 0/12 → 7/12 (storage-refactor session bootstrap
fixes) → 10/12 with this commit.
1. Backup service crashes on backend startup with
`TypeError: Cannot read properties of undefined (reading 'replace')`
from node-cron's expression parser.
Root cause: `backup_schedule` stores a UI label like "weekly", while
`backup_schedule_cron` stores the actual cron expression. Startup
code read the label and passed it straight to cron.schedule() —
"weekly" is not a cron expression.
Fix in startBackupService(): read backup_schedule_cron first; fall
back to mapping known labels (hourly/daily/weekly/monthly) to cron
expressions; back-compat for deployments that wrote a cron expression
into the legacy backup_schedule field.
2. Backup manifest retrieval fails with
`SyntaxError: Unexpected token 'a', "applicatio"...` when the
manifest format is YAML.
Root cause: getBackupManifest() downloads the s3:// manifest to a
tmp file hardcoded as `manifest-N.json`. loadManifest() then
detects format from extension only — sees .json, runs JSON.parse on
YAML content (which starts with "application: …"), fails.
Fix in backupManifest.loadManifest(): detect format from BOTH the
extension AND the content's first non-whitespace character. JSON
starts with { or [; anything else falls through to yaml.load.
Backwards compatible — extension is still authoritative when present
AND content matches.
3. Test assertion `expect(backupRun.total_size_bytes).toBeGreaterThan(0)`
fails with "received value must be a number or bigint" because pg
driver returns bigint columns as strings. Coerce via Number() in
the test.
Remaining 2 failures (out of scope here, both are spec-level drift):
- "should include database backup" expects the runBackup() flow to
upload the database backup file at S3 key `database/db-backup.sql`.
Current implementation reads db backup metadata for the manifest but
does not upload the file itself. Missing feature, not a test bug.
- "should only upload changed files" expects manifest.incremental.
modified_files_count. Implementation writes backupType: 'incremental'
on the run row but no per-run incremental subobject in the manifest.
Field shape mismatch.
