- InnoDB tries to write FILE_CHECKPOINT marker during early recovery when log file size is insufficient. While updating the log checkpoint at the end of the recovery, InnoDB must already have written out all pending changes to the persistent files. To complete the checkpoint, InnoDB has to write some log records for the checkpoint and to update the checkpoint header. If the server gets killed before updating the checkpoint header then it would lead the logfile to be unrecoverable. - This patch avoids FILE_CHECKPOINT marker during early recovery and narrows down the window of opportunity to make the log file unrecoverable.
