The previous deploy mechanism kept the old version under {target}.old
just long enough to swap, then deleted it — no way back if the new
report had a runtime bug only visible at use time.
Now each deploy keeps the previous active version under
{FolderName}.backup-yyyyMMdd-HHmmss/. The N most recent are kept
(MaxBackups, default 3) and older ones are pruned in best-effort.
UI in Settings → Avancés → Outil Report :
- "Conserver N backups" input (0 = no history, back to v0.12 behavior)
- List of backups with date + size + cryptic folder name + per-row "↶ Revert"
- Confirmation dialog: "Revert to {date}? The currently deployed
version will itself be saved as a new backup, so you can switch back."
Implementation
- IReportToolDeployer: + ListBackupsAsync, + RevertAsync, + BackupInfo,
+ DeployStatus.BackupNotFound.
- ReportToolDeployer: deploy renames {target} → backup-{ts}; PruneOldBackups
trims to MaxBackups; RevertAsync atomically swaps current ↔ chosen
backup, the previous current becoming itself a fresh backup.
- ReportBackupViewModel + DataTemplate for the list rows.
- Strings: backup labels, "↶ Revert", confirmation message.
Caveats documented in the design discussion:
- Backups cover ONLY the report tool files. DB migrations are not reverted
(irreversible). If a migration broke the schema, that's a separate fix.
- No HTTP-HEAD post-deploy auto-revert: too fragile for false positives.
Revert stays a deliberate manual action.
Versions bumped to 0.13.0.
