Marko Mäkelä b737d09dbc MDEV-29905 Change buffer operations fail to check for log file overflow ... Every operation that is going to write redo log is supposed to invoke log_free_check() before acquiring any latches. If there is a risk of log buffer overrun, a log checkpoint would be triggered by that call. ibuf_merge_space(), ibuf_merge_in_background(), ibuf_delete_for_discarded_space(): Invoke log_free_check() when the current thread is not holding any page latches. Unfortunately, in lower-level code called from ibuf_insert() or ibuf_merge_or_delete_for_page(), some page latches may be held and a call to log_free_check() could hang. ibuf_set_bitmap_for_bulk_load(): Use the caller's mini-transaction. The caller should have invoked log_free_check() while not holding any page latches.		2022-11-08 11:37:43 +02:00
