| syncDBs() X-Ref |
| Wait until the selected slave has caught up to the master. This allows us to use the slave for things that were committed in a previous part of this batch process. |
| execute() X-Ref |
| Execute parent or child depending on the isChild option |
| executeParent() X-Ref |
| Execute the parent process |
| checkTrackingTable() X-Ref |
| Make sure the tracking table exists and isn't empty return: bool |
| startSlaveProcs() X-Ref |
| Start the worker processes. These processes will listen on stdin for commands. This necessary because text recompression is slow: loading, compressing and writing are all slow. |
| killSlaveProcs() X-Ref |
| Gracefully terminate the child processes |
| dispatch( ) X-Ref |
| Dispatch a command to the next available slave. This may block until a slave finishes its work and becomes available. |
| dispatchToSlave( $slaveId, $args ) X-Ref |
| Dispatch a command to a specified slave param: int $slaveId param: array|string $args |
| doAllPages() X-Ref |
| Move all tracked pages to the new clusters |
| report( $label, $current, $end ) X-Ref |
| Display a progress report param: string $label param: int $current param: int $end |
| doAllOrphans() X-Ref |
| Move all orphan text to the new clusters |
| executeChild() X-Ref |
| Main entry point for worker processes |
| doPage( $pageId ) X-Ref |
| Move tracked text in a given page param: int $pageId |
| moveTextRow( $textId, $url ) X-Ref |
| Atomic move operation. Write the new URL to the text table and set the bt_moved flag. This is done in a single transaction to provide restartable behavior without data loss. The transaction is kept short to reduce locking. param: int $textId param: string $url |
| finishIncompleteMoves( $conds ) X-Ref |
| Moves are done in two phases: bt_new_url and then bt_moved. - bt_new_url indicates that the text has been copied to the new cluster. - bt_moved indicates that the text table has been updated. This function completes any moves that only have done bt_new_url. This can happen when the script is interrupted, or when --copy-only is used. param: array $conds |
| getTargetCluster() X-Ref |
| Returns the name of the next target cluster return: string |
| getExtDB( $cluster ) X-Ref |
| Gets a DB master connection for the given external cluster name param: string $cluster return: DatabaseBase |
| doOrphanList( $textIds ) X-Ref |
| Move an orphan text_id to the new cluster param: array $textIds |
| waitForSlaves() X-Ref |
| Wait for slaves (quietly) |
Class: CgzCopyTransaction - X-Ref
Class to represent a recompression operation for a single CGZ blob| __construct( $parent, $blobClass ) X-Ref |
| Create a transaction from a RecompressTracked object param: RecompressTracked $parent param: string $blobClass |
| addItem( $text, $textId ) X-Ref |
| Add text. Returns false if it's ready to commit. param: string $text param: int $textId return: bool |
| getSize() X-Ref |
| No description |
| recompress() X-Ref |
| Recompress text after some aberrant modification |
| commit() X-Ref |
| Commit the blob. Does nothing if no text items have been added. May skip the move if --copy-only is set. |
