buf_page_get_low(): Do not try to re-evict the page if it is multiply buffer-fixed. In commit 7cffb5f6 (MDEV-23399) a livelock was introduced. If multiple threads are concurrently requesting the same secondary index leaf page in buf_page_get_low() and innodb_change_buffering_debug is set, all threads would try to evict the page in a busy loop, never succeeding because the block is buffer-fixed by other threads. Thanks to Roel Van de Paar for reporting the original failure and Elena Stepanova for producing an "rr replay" trace.

rocksdb_checkpoint_request() should call FlushWAL(sync=true) (which does write-out and sync), not just SyncWAL() (which just syncs without writing out) Followup: the test requires debug sync facility (This is a backport to 10.5)

The code compares two query plans with identical costs, the plan with lateral is the same as one without. Introduce a small difference to cost numbers to prefer non-lateral plan in this case.

- Aborting of fulltext index creation fails to remove the index from sys indexes table. When we try to reload the table definition, InnoDB fails with index count mismatch error. InnoDB should remove the index from sys indexes while rollbacking the secondary index creation.

memory barrier on ARM As suggested in the said JIRA ticket based on the contribution done by the community (in an attempt to optimize the spin-loop) the said approach was evaluated against MariaDB Server 10.5 and found to help improve throughput in the range of 2-5%. Note: 10.6 timing graph and model are different as home-brew mutexes are replaced with pthread mutexes. Said patch has mixed impact on 10.6 so not recommended for 10.6.

- Importing table operation fails to punch the hole in the filesystem when page compressed table is involved. To achieve that, InnoDB firstly punches the hole for the IOBuffer size(1MB). After that, InnoDB should write page by page when page compression is involved.

As pointed out by Andrei Elkin, the previous fix did not fix one race condition that may have caused the observed hang. innodb_log_flush_request(): If we are enqueueing the very first request at the same time the log write is being completed, we must ensure that a near-concurrent call to log_flush_notify() will not result in a missed notification. We guarantee this by release-acquire operations on log_requests.start and log_sys.flushed_to_disk_lsn. log_flush_notify_and_unlock(): Cleanup: Always release the mutex. log_sys_t::get_flushed_lsn(): Use acquire memory order. log_sys_t::set_flushed_lsn(): Use release memory order. log_sys_t::set_lsn(): Use release memory order. log_sys_t::get_lsn(): Use relaxed memory order by default, and allow the caller to specify acquire memory order explicitly. Whenever the log_sys.mutex is being held or when log writes are prohibited during startup, we can use a relaxed load. Likewise, in some assertions where reading a stale value of log_sys.lsn should not matter, we can use a relaxed load. This will cause some additional instructions to be emitted on architectures that do not implement Total Store Ordering (TSO), such as POWER, ARM, and RISC-V Weak Memory Ordering (RVWMO).

Add condition on trx->state == TRX_STATE_COMMITTED_IN_MEMORY in order to avoid unnecessary work. If a transaction has already been committed or rolled back, it will release its locks in lock_release() and let the waiting thread(s) continue execution. Let BF wait on lock_rec_has_to_wait and if necessary other BF is replayed. wsrep_trx_order_before If BF is not even replicated yet then they are ordered correctly. bg_wsrep_kill_trx Make sure victim_trx is found and check also its state. If state is TRX_STATE_COMMITTED_IN_MEMORY transaction is already committed or rolled back and will release it locks soon. wsrep_assert_no_bf_bf_wait Transaction requesting new record lock should be TRX_STATE_ACTIVE Conflicting transaction can be in states TRX_STATE_ACTIVE, TRX_STATE_COMMITTED_IN_MEMORY or in TRX_STATE_PREPARED. If conflicting transaction is already committed in memory or prepared we should wait. When transaction is committed in memory we held trx mutex, but not lock_sys->mutex. Therefore, we could end here before transaction has time to do lock_release() that is protected with lock_sys->mutex. lock_rec_has_to_wait We very well can let bf to wait normally as other BF will be replayed in case of conflict. For debug builds we will do additional sanity checks to catch unsupported bf wait if any. wsrep_kill_victim Check is victim already in TRX_STATE_COMMITTED_IN_MEMORY state and if it is we can return. lock_rec_dequeue_from_page lock_rec_unlock Remove unnecessary wsrep_assert_no_bf_bf_wait function calls. We can very well let BF wait here.

This reverts commit 44885273. Reverting this commit is necessary to fix missing-breaks errors in the Debian packaging. The original fix was also not entirely necessary as a fix to the original problem. Partially also reverts commit e7c7f5c1 where this unsorted debian/control file was sorted.

Starting with MariaDB 10.5, roughly after MDEV-23855 was fixed, we are observing sporadic hangs during the execution of the RESET MASTER statement. We are hoping to fix the hangs with these changes, but due to the rather infrequent occurrence of the hangs and our inability to reliably reproduce the hangs, we cannot be sure of this. What we do know is that innodb_force_recovery=2 (or a larger setting) will prevent srv_master_callback (the former srv_master_thread) from running. In that mode, periodic log flushes would never occur and RESET MASTER could hang indefinitely. That is demonstrated by the new test case that was developed by Andrei Elkin. We fix this case by implementing a special case for it. This also includes some code cleanup and renames of misleadingly named code. The interface has nothing to do with log checkpoints in the storage engine; it is only about requesting log writes to be persistent. handlerton::commit_checkpoint_request, commit_checkpoint_notify_ha(): Remove the unused parameter hton. log_requests.start: Replaces pending_checkpoint_list. log_requests.end: Replaces pending_checkpoint_list_end. log_requests.mutex: Replaces pending_checkpoint_mutex. log_flush_notify_and_unlock(), log_flush_notify(): Replaces innobase_mysql_log_notify(). The new implementation should be functionally equivalent to the old one. innodb_log_flush_request(): Replaces innobase_checkpoint_request(). Implement a fast path for common cases, and reduce the mutex hold time. POSSIBLE FIX OF THE HANG: We will invoke commit_checkpoint_notify_ha() for the current request if it is already satisfied, as well as invoke log_flush_notify_and_unlock() for any satisfied requests. log_write(): Invoke log_flush_notify() when the write is already durable. This was missing WITH_PMEM when the log is in persistent memory. Reviewed by: Vladislav Vaintroub

we need to stop server instance on upgrade, but it may be started either by SysV init script or by SystemD. this commit adds `mysql` target to `systemctl stop` call. `mysql` may be the name of initscript or an alias while `mariadb` is a systemd unit file.

`mallinfo` is deprecated since glibc 2.33 and has been replaced by mallinfo2. The deprecation causes building the server to fail if glibc version is > 2.33. Check if mallinfo2 exist on the system and use it instead.

The function row_upd_clust_step() is invoking several static functions, some of which used to commit the mini-transaction in some cases. If innobase_get_computed_value() would fail due to some reason, we would fail to invoke mtr_t::commit() and release buffer pool page latches. This would likely lead to a hanging server later. This regression was introduced in commit 97db6c15 (MDEV-20618). row_upd_index_is_referenced(), row_upd_sec_index_entry(), row_upd_sec_index_entry(): Cleanup: Replace some ibool with bool. row_upd_clust_rec_by_insert(), row_upd_clust_rec(): Guarantee that the mini-transaction will always remain in active state. row_upd_del_mark_clust_rec(): Guarantee that the mini-transaction will always remain in active state. This fixes one "leak" of mini-transaction on DB_COMPUTE_VALUE_FAILED. row_upd_clust_step(): Use only one return path, which will always invoke mtr.commit(). After a failed row_upd_store_row() call, we will no longer "leak" the mini-transaction. This fix was verified by RQG on 10.6 (depending on MDEV-371 that was introduced in 10.4). Unfortunately, it is challenging to create a regression test for this, and a test case could soon become invalid as more bugs in virtual column evaluation are fixed.

A side effect of the MDEV-24589 bug fix is that if FLUSH TABLE...FOR EXPORT is initiated before the history of an earlier DROP INDEX operation has been purged, then the data file will contain allocated pages that belonged to the dropped indexes. These pages would never be freed after a subsequent IMPORT TABLESPACE. We will work around this regression by making IMPORT TABLESPACE tolerate pages that refer to an unknown index.
