Synchronize gpbackup history with the standby coordinator. - #111
Merged
Conversation
Keep the primary operation result while making database and row close failures visible.
Return connection, SQLite, and local cleanup failures to the policy boundary without changing best-effort exit status.
Disable automatic sync in shared helpers and restore the original standby history after the dedicated scenario.
Pass remote paths directly to rsync while retaining shell quoting for SSH install and cleanup commands.

There was a problem hiding this comment.
I found two issues in the standby history synchronization path.
Expose --history-sync-standby-timeout as integer seconds in gpbackup and sync-capable gpBackMan commands. Use int to match existing CLI conventions, default to 300 seconds, and cap values at one day to catch accidental settings without excluding slow transfers. Create one context deadline after SQLite snapshot validation and share its remaining budget across rsync and remote install. This keeps discovery and local snapshot work outside the limit and prevents each transport stage from restarting the timeout. Run rsync and ssh with CommandContext and BatchMode so stalled processes are terminated without waiting for interactive authentication. Use an independent 120-second context for failure cleanup so remote temporary files can still be removed after the transport deadline expires while cleanup remains bounded. Preserve both primary and cleanup errors and keep automatic synchronization best-effort while history-sync stays strict.
Pass remote paths with rsync's `-s` option so shell metacharacters are not interpreted by the remote shell, and document the resulting rsync 3.0.0 requirement.
When rsync or ssh succeeds and the context deadline fires immediately after, the successful transfer was incorrectly treated as a timeout. Only prefer ctx.Err() when the command itself returned an error.

gpbackup_history.dbis stored on the active primary coordinator and is not automatically available on the standby. After a failover, the promoted coordinator may have missing or outdated backup history, which affects backup discovery and management.This change keeps the cluster history database synchronized with an available standby coordinator:
gpbackupautomatically synchronizes history after a successful backup.gpbackman history-synccommand allows synchronization to be started manually.--no-history-sync-standby.Only
gpbackup_history.dbis synchronized. Backup data, reports, and other backup artifacts are not included.Unit and end-to-end coverage were added, and the related user documentation was updated.
