The original problem for MDEV-21953 was that while a thread was waiting in for another threads to commit in 'log_and_order', it had the MDL_BACKUP_COMMIT lock. The backup thread was waiting to get the MDL_BACKUP_WAIT_COMMIT lock, which blocks all new MDL_BACKUP_COMMIT locks. This causes a deadlock as the waited-for thread can never get past the MDL_BACKUP_COMMIT lock in ha_commit_trans. The main part of the bug fix is to release the MDL_BACKUP_COMMIT lock while a thread is waiting for other 'previous' threads to commit. This ensures that no transactional thread keeps MDL_BACKUP_COMMIT while waiting, which ensures that there are no deadlocks anymore. --- sql/handler.cc | 101 ++++++++++++++++++++++++----------------------- sql/handler.h | 2 +- sql/log.cc | 55 +++++++++++++++++++++++--- sql/sql_class.cc | 30 ++++++++++++-- sql/sql_class.h | 3 ++ sql/xa.cc | 2 +- 6 files changed, 134 insertions(+), 59 deletions(-) diff --git a/sql/handler.cc b/sql/handler.cc index 40dea349272..d7562bcd2ae 100644 --- a/sql/handler.cc +++ b/sql/handler.cc @@ -114,7 +114,7 @@ static TYPELIB known_extensions= {0,"known_exts", NULL, NULL}; uint known_extensions_id= 0; static int commit_one_phase_2(THD *thd, bool all, THD_TRANS *trans, - bool is_real_trans, bool rw_trans); + bool is_real_trans); static plugin_ref ha_default_plugin(THD *thd) @@ -1490,9 +1490,40 @@ int ha_commit_trans(THD *thd, bool all) /* rw_trans is TRUE when we in a transaction changing data */ bool rw_trans= is_real_trans && (rw_ha_count > (thd->is_current_stmt_binlog_disabled()?0U:1U)); + MDL_request mdl_backup; DBUG_PRINT("info", ("is_real_trans: %d rw_trans: %d rw_ha_count: %d", is_real_trans, rw_trans, rw_ha_count)); + if (rw_trans) + { + /* + Acquire a metadata lock which will ensure that COMMIT is blocked + by an active FLUSH TABLES WITH READ LOCK (and vice versa: + COMMIT in progress blocks FTWRL). + + We allow the owner of FTWRL to COMMIT; we assume that it knows + what it does. + */ + mdl_backup.init(MDL_key::BACKUP, "", "", MDL_BACKUP_COMMIT, MDL_EXPLICIT); + + if (!WSREP(thd)) + { + if (thd->mdl_context.acquire_lock(&mdl_backup, + thd->variables.lock_wait_timeout)) + { + ha_rollback_trans(thd, all); + DBUG_RETURN(1); + } + thd->backup_commit_lock= &mdl_backup; + } + DEBUG_SYNC(thd, "ha_commit_trans_after_acquire_commit_lock"); + + /* Use shortcut as we already have the MDL_BACKUP_COMMIT lock */ + ha_maria::implicit_commit(thd, TRUE); + } + else + ha_maria_implicit_commit(thd, TRUE); + if (rw_trans && opt_readonly && !(thd->security_ctx->master_access & SUPER_ACL) && @@ -1532,7 +1563,7 @@ int ha_commit_trans(THD *thd, bool all) // Here, the call will not commit inside InnoDB.

Because we no longer do an extra lookup of the tablespace between fil_io() and the completion of the operation, we must give fil_node_t::complete_io() a chance to decrement the counter. --- storage/innobase/fil/fil0fil.cc | 27 ++++++++++++++------------- 1 file changed, 14 insertions(+), 13 deletions(-) diff --git a/storage/innobase/fil/fil0fil.cc b/storage/innobase/fil/fil0fil.cc index 21743a0e076..a654451f986 100644 --- a/storage/innobase/fil/fil0fil.cc +++ b/storage/innobase/fil/fil0fil.cc @@ -561,11 +561,9 @@ fil_try_to_close_file_in_LRU( continue; } - if (node->n_pending_flushes > 0) { - + if (const auto n = node->n_pending_flushes) { ib::info() << "Cannot close file " << node->name - << ", because n_pending_flushes " - << node->n_pending_flushes; + << ", because n_pending_flushes " << n; } if (node->needs_flush) { @@ -915,7 +913,7 @@ pfs_os_file_t fil_node_t::close_to_free(bool detach_handle) fil_system.unflushed_spaces.remove(*space); } - if (n_pending) + if (n_pending || n_pending_flushes) { mutex_exit(&fil_system.mutex); os_thread_sleep(100); @@ -939,7 +937,6 @@ pfs_os_file_t fil_node_t::close_to_free(bool detach_handle) ut_ad(UT_LIST_GET_LEN(fil_system.LRU) > 0); UT_LIST_REMOVE(fil_system.LRU, this); } - ut_a(!n_pending_flushes); ut_a(!being_extended); if (detach_handle) { @@ -982,7 +979,6 @@ std::vector fil_system_t::detach(fil_space_t *space, temp_space= nullptr; ut_a(space->magic_n == FIL_SPACE_MAGIC_N); - ut_a(space->n_pending_flushes == 0); for (fil_node_t* node= UT_LIST_GET_FIRST(space->chain); node; node= UT_LIST_GET_NEXT(chain, node)) @@ -1003,6 +999,7 @@ std::vector fil_system_t::detach(fil_space_t *space, handles.push_back(handle); } + ut_ad(space->n_pending_flushes == 0); return handles; } @@ -1612,7 +1609,8 @@ next: if (!node->is_open()) { goto next; } - if (!node->n_pending) { + if (!node->n_pending + && !node->n_pending_flushes) { node->close(); goto next; } @@ -1620,7 +1618,9 @@ next: ib::error() << "File '" << node->name << "' has " << node->n_pending - << " operations"; + << " operations and " + << node->n_pending_flushes + << " flushes"; } space = UT_LIST_GET_NEXT(space_list, space); @@ -1988,17 +1988,18 @@ fil_check_pending_io( *node = UT_LIST_GET_FIRST(space->chain); - if (space->n_pending_flushes > 0 || (*node)->n_pending > 0) { + const auto f = space->n_pending_flushes; + const auto p = (*node)->n_pending; + if (f || p) { ut_a(!(*node)->being_extended); /* Give a warning every 10 second, starting after 1 second */ if ((count % 500) == 50) { ib::info() << "Trying to delete" " tablespace '" << space->name - << "' but there are " - << space->n_pending_flushes - << " flushes and " << (*node)->n_pending + << "' but there are " << f + << " flushes and " << p << " pending i/o's on it."; } From d34523faee248c71d1e335a75977cc71debe67d9 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marko=20M=C3=A4kel=C3=A4?= Date: Fri, 25 Sep 2020 17:29:33 +0300 Subject: [PATCH 032/323] MDEV-15053 fixup: Remove redundant code fil_node_t::close_to_free(): Remove some duplicated code that was added in commit b1ab211dee599eabd9a5b886fafa3adea29ae041. --- storage/innobase/fil/fil0fil.cc | 11 ----------- 1 file changed, 11 deletions(-) diff --git a/storage/innobase/fil/fil0fil.cc b/storage/innobase/fil/fil0fil.cc index a654451f986..0325dce8422 100644 --- a/storage/innobase/fil/fil0fil.cc +++ b/storage/innobase/fil/fil0fil.cc @@ -921,17 +921,6 @@ pfs_os_file_t fil_node_t::close_to_free(bool detach_handle) continue; } - if (srv_file_flush_method == SRV_O_DIRECT_NO_FSYNC) - { - ut_ad(!space->is_in_unflushed_spaces); - ut_ad(fil_space_is_flushed(space)); - } - else if (space->is_in_unflushed_spaces && fil_space_is_flushed(space)) - { - space->is_in_unflushed_spaces= false; - fil_system.unflushed_spaces.remove(*space); - } - if (fil_space_belongs_in_lru(space)) { ut_ad(UT_LIST_GET_LEN(fil_system.LRU) > 0); From e8b05ce503dffc2d95d1583b7c89403d320e263c Mon Sep 17 00:00:00 2001 From: Thirunarayanan Balathandayuthapani Date: Tue, 8 Sep 2020 17:24:08 +0530 Subject: [PATCH 033/323] MDEV-23675 Assertion `pos < table->n_def' fails in dict_table_get_nth_col - During insertion of clustered inde, InnoDB does the check for foreign key constraints.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

Specifically, in lock_rec_insert_by_trx_age() the predicate !lock_rec_has_to_wait_in_queue(in_lock) would hold even though an active transaction is already holding an exclusive lock. This was observed between two DELETE of the same clustered index record. The HASH_DELETE invocation in lock_rec_enqueue_waiting() may be related. Due to lack of progress in diagnosing the problem, we will deprecate the option and issue a warning that using it may corrupt data.

It also turns out that lock_rec_lock() acquires lock_sys_t::mutex and then carries on to call lock_rec_enqueue_waiting(), which may invoke THDVAR() via thd_lock_wait_timeout(). This call is problematic if THDVAR() had never been invoked in that thread earlier. innobase_trx_init(): Let us invoke THDVAR() at the start of an InnoDB transaction so that future invocations of THDVAR() will avoid LOCK_global_system_variables acquisition on the same THD. Because the first call to intern_sys_var_ptr() will initialize all session variables by not passing the offset to sync_dynamic_session_variables(), this will indeed make any future THDVAR() invocation mutex-free. There are some THDVAR() calls in other code (related to indexed virtual columns, fulltext indexes, and DDL operations). No SAFE_MUTEX warning was known for those, but there does not appear to be any replication test coverage for indexed virtual columns or fulltext indexes. DDL should be covered, and perhaps DDL code paths were already invoking THDVAR() while not holding any InnoDB mutex. Side note: MySQL should avoid this type of deadlocks since mysql/mysql-server@4d275c89954685e2ed1b368812b3b5a29ddf9389. MariaDB never defined alloc_and_copy_thd_dynamic_variables(), because we prefer to avoid overhead during connection creation. An important part of the deadlock could be the current handling of SET GLOBAL binlog_checksum=NONE; and similar assignments. In binlog_checksum_update(), we would hold LOCK_global_system_variables while potentially acquiring LOCK_commit_ordered in MYSQL_BIN_LOG::open(). Even if that code was changed later to release LOCK_global_system_variables during the write to mysql_bin_log, it could be a good idea for performance to avoid invoking the expensive code path of THDVAR() while holding any InnoDB mutexes, such as lock_sys.mutex in lock_rec_enqueue_waiting().

Due to MDEV-16664, the parameter innodb_lock_schedule_algorithm=VATS is not enabled by default. The purpose of the added assertions was to enforce the invariant that Galera replication cannot be enabled together with VATS due to MDEV-12837. However, upon closer inspection, it is obvious that the variable 'lock' may be assigned to the null pointer if no match is found in the previous->hash list. lock_grant_and_move_on_page(), lock_grant_and_move_on_rec(): Assert !lock->trx->is_wsrep() only after ensuring that lock is not a null pointer. --- mysql-test/suite/innodb/t/update-cascade.combinations | 5 +++++ storage/innobase/lock/lock0lock.cc | 7 +++---- 2 files changed, 8 insertions(+), 4 deletions(-) create mode 100644 mysql-test/suite/innodb/t/update-cascade.combinations diff --git a/mysql-test/suite/innodb/t/update-cascade.combinations b/mysql-test/suite/innodb/t/update-cascade.combinations new file mode 100644 index 00000000000..8fb4862675b --- /dev/null +++ b/mysql-test/suite/innodb/t/update-cascade.combinations @@ -0,0 +1,5 @@ +[FCFS] +--innodb-lock-schedule-algorithm=FCFS + +[VATS] +--innodb-lock-schedule-algorithm=VATS diff --git a/storage/innobase/lock/lock0lock.cc b/storage/innobase/lock/lock0lock.cc index e48ac6bcc92..913c80027bf 100644 --- a/storage/innobase/lock/lock0lock.cc +++ b/storage/innobase/lock/lock0lock.cc @@ -2306,12 +2306,12 @@ lock_grant_and_move_on_page(ulint rec_fold, ulint space, ulint page_no) lock = previous->hash; } - ut_ad(!lock->trx->is_wsrep()); ut_ad(previous->hash == lock || previous == lock); /* Grant locks if there are no conflicting locks ahead.

One of these range conditions must be fully covered by another range condition that is used later in the OR formula. Additionally at least one of these condition should be ANDed with a sargable range condition supported by a different index. There were several attempts to fix related problems for OR conditions after the backport of range optimizer code from MySQL (commit 0e19f3e36f7842583feb6bead2c2600cd620bced). Unfortunately the first of these fixes contained typo remained unnoticed until recently. This typo bug led to rejection of valid range accesses. This patch fixed this typo bug. The fix revealed another two bugs: one in a constructor for SEL_ARG, the other in the function tree_or(). Both are fixed in this patch. --- mysql-test/r/range.result | 74 ++++++++++++++++++- mysql-test/r/range_mrr_icp.result | 74 ++++++++++++++++++- .../r/range_vs_index_merge_innodb.result | 2 +- mysql-test/t/range.test | 42 +++++++++++ sql/opt_range.cc | 20 +++-- 5 files changed, 201 insertions(+), 11 deletions(-) diff --git a/mysql-test/r/range.result b/mysql-test/r/range.result index 26ea2c6d323..7299982e72d 100644 --- a/mysql-test/r/range.result +++ b/mysql-test/r/range.result @@ -1274,7 +1274,7 @@ SELECT * FROM t1 WHERE 5 <= a AND b = 3 OR 3 <= a; id select_type table type possible_keys key key_len ref rows Extra -1 SIMPLE t1 range a a 5 NULL 4 Using where; Using index +1 SIMPLE t1 range a a 5 NULL 3 Using where; Using index SELECT * FROM t1 WHERE 3 <= a AND a <= 5 OR 5 <= a AND b = 3 OR @@ -3054,5 +3054,77 @@ a b set eq_range_index_dive_limit=default; drop table t1; # +# MDEV-23811: Both disjunct of WHERE condition contain range conditions +# for the same index such that the second range condition +# fully covers the first one.

Analysis: ---------- MYSQL_UPGRADE of the master breaks the replication when the query logging is enabled with FILE/NONE 'log-output' option on the slave. mysql_upgrade modifies the 'general_log' and 'slow_log' tables after the logging is disabled as below: SET @old_log_state = @@global.general_log; SET GLOBAL general_log = 'OFF'; ALTER TABLE general_log MODIFY event_time TIMESTAMP NOT NULL, ( .... ); SET GLOBAL general_log = @old_log_state; and SET @old_log_state = @@global.slow_query_log; SET GLOBAL slow_query_log = 'OFF'; ALTER TABLE slow_log MODIFY start_time TIMESTAMP NOT NULL, ( .... ); SET GLOBAL slow_query_log = @old_log_state; In the binary log, only the ALTER statements are logged but not the SET statements which turns ON/OFF the logging. So when the slave replays the binary log,the ALTER of LOG tables throws an error since the logging is enabled. Also the 'log-output' option is not checked to determine whether to allow/disallow the ALTER operation. Fix: ---- The 'log-output' option is included in the check while determining whether the query logging happens using the log tables.

charset=UTF-8 Content-Transfer-Encoding: 8bit Problem is that dropping of fts table and sync of fts table happens concurrently during fts optimize thread shutdown. fts_optimize_remove_table() is executed by a user thread that performs DDL, and that the fts_optimize_wq may be removed if fts_optimize_shutdown() has started executing. fts_optimize_remove_table() doesn't remove the table from the queue and it leads to above scenario. While removing the table from fts_optimize_wq, if the table can't be removed then wait till fts_optimize_thread shuts down.

charset=UTF-8 Content-Transfer-Encoding: 8bit handler_rowid_filter_check can return CHECK_ABORTED_BY_USER. All the functions that call row_search_idx_cond_check handle the CHECK_ABORTED_BY_USER return value. So return it rather than generating an error. This incorrect handling was introduced in MDEV-21794 (8d85715d507d).

Upgrade to using Ubuntu 20.04 (Focal) as the baseline distro version now that Travis-CI has made it available. Drop Xenial and all the excess repositories Xenial needed. Now we only Focal and one Bionic build to keep things simple and streamlined. Keep GCC-7/Clang-7 as the older compiler, and start using GCC-10 and Clang-10 as the newer compiler. Assume that if both of them build OK, than the intermediate versions would be OK as well. Print 'apt-cache policy' to make it transparent in build logs what repositories was used for build dependencies. Remove temporary workaround from homebrew install step as Travis-CI has fixed the original issue. Revert ignoring results form build that previously failed on the test main.thread_pool_info as MDEV-20372 is not fixed. Keep arm64 failures ignored due to MDEV-23955. Allow failures for the test main.column_compression 'innodb' due to MDEV-23954. --- .travis.yml | 66 ++++++++++++++++++++++++++--------------------------- 1 file changed, 33 insertions(+), 33 deletions(-) diff --git a/.travis.yml b/.travis.yml index 46588177faf..7395b48c350 100644 --- a/.travis.yml +++ b/.travis.yml @@ -1,7 +1,12 @@ # vim ft=yaml # travis-ci.org definition -dist: bionic +# NOTE TO MERGERS: Most of the contents in the Travis-CI configuration has been +# tailored for a specific release or MariaDB.

During recovery, buf_pool.flush_rbt used to guarantee the ordering. However, we can allow the buf_pool.flush_list to be in an arbitrary order during recovery, and simply ensure that it is in the correct order by the time a log checkpoint needs to be executed. recv_sys_t::apply(): To keep it simple, we will always flush the buffer pool at the end of each batch. Note that log_checkpoint() will invoke recv_sys_t::apply() in case a checkpoint is initiated during the last batch of recovery, when we already allow writes to data pages and the redo log.

First, if the netcat utility is used for streaming (but not socat), then in accordance with its command line syntax, we need to remove the square brackets around the IPv6 address. However, for socat, the address must contain square brackets, as before. Secondly, if an IPv6 address is used, then from the joiner side for a number of systems (such as Debian) we need to explicitly specify the "-6" option, otherwise a listening socket with an IPv6 address may not be created. This patch also contains code improvements in the wsrep_sst_common. Changed the code that pars the connection address - fixed the shortcomings that sometimes led to incorrect parsing of parameters when using shells other than the latest versions of bash. Also, this patch removes the duplicate code that is intended for parsing the connection address and which was located in the wsrep_sst_mariabackup file, since all the necessary actions have already been done in wsrep_sst_common and there they are done in such a way that any shell is supported, not just bash. The fix does not require separate tests, since all the necessary tests are already present in the galera_3nodes suite. On the contrary, after this fix, tests using IPv6 addresses can be removed from the disabled list (this will be done in a separate commit related to MDEV-23659). --- .../t/galera_ipv6_mariabackup.cnf | 5 ++ scripts/wsrep_sst_common.sh | 46 +++++++++++++- scripts/wsrep_sst_mariabackup.sh | 63 ++++++++++--------- 3 files changed, 83 insertions(+), 31 deletions(-) diff --git a/mysql-test/suite/galera_3nodes/t/galera_ipv6_mariabackup.cnf b/mysql-test/suite/galera_3nodes/t/galera_ipv6_mariabackup.cnf index 3861b17557d..8432b1c368c 100644 --- a/mysql-test/suite/galera_3nodes/t/galera_ipv6_mariabackup.cnf +++ b/mysql-test/suite/galera_3nodes/t/galera_ipv6_mariabackup.cnf @@ -10,6 +10,7 @@ wsrep-cluster-address=gcomm:// wsrep_provider_options='base_host=[::1];base_port=@mysqld.1.#galera_port;gmcast.listen_addr=tcp://[::]:@mysqld.1.#galera_port;ist.recv_addr=[::1]:@mysqld.1.#ist_port' wsrep_sst_receive_address='[::1]:@mysqld.1.#sst_port' wsrep_node_incoming_address='[::1]:@mysqld.1.port' +wsrep_node_name=node_1 bind-address=:: [mysqld.2] @@ -17,6 +18,8 @@ wsrep_cluster_address='gcomm://[::1]:@mysqld.1.#galera_port' wsrep_provider_options='base_host=[::1];base_port=@mysqld.2.#galera_port;gmcast.listen_addr=tcp://[::]:@mysqld.2.#galera_port;ist.recv_addr=[::1]:@mysqld.2.#ist_port' wsrep_sst_receive_address='[::1]:@mysqld.2.#sst_port' wsrep_node_incoming_address='[::1]:@mysqld.2.port' +wsrep_node_name=node_2 +wsrep_sst_donor=node_1 bind-address=:: [mysqld.3] @@ -24,6 +27,8 @@ wsrep_cluster_address='gcomm://[::1]:@mysqld.1.#galera_port' wsrep_provider_options='base_host=[::1];base_port=@mysqld.3.#galera_port;gmcast.listen_addr=tcp://[::]:@mysqld.3.#galera_port;ist.recv_addr=[::1]:@mysqld.3.#ist_port' wsrep_sst_receive_address='[::1]:@mysqld.3.#sst_port' wsrep_node_incoming_address='[::1]:@mysqld.3.port' +wsrep_node_name=node_3 +wsrep_sst_donor=node_1 bind-address=:: [SST] diff --git a/scripts/wsrep_sst_common.sh b/scripts/wsrep_sst_common.sh index ee7817a1550..f5adf0b0fd8 100644 --- a/scripts/wsrep_sst_common.sh +++ b/scripts/wsrep_sst_common.sh @@ -45,28 +45,68 @@ case "$1" in case "${WSREP_SST_OPT_ADDR}" in \[*) # IPv6 + # Remove the starting and ending square brackets, if present: addr_no_bracket=${WSREP_SST_OPT_ADDR#\[} readonly WSREP_SST_OPT_HOST_UNESCAPED=${addr_no_bracket%%\]*} + # Square brackets are needed in most cases: readonly WSREP_SST_OPT_HOST="[${WSREP_SST_OPT_HOST_UNESCAPED}]" + # Some utilities and subsequent code require an address + # without square brackets: readonly WSREP_SST_OPT_HOST_ESCAPED="\\[${WSREP_SST_OPT_HOST_UNESCAPED}\\]" + readonly WSREP_SST_OPT_HOST_IPv6=1 ;;

The configuration parameters will be changed as follows: innodb_lru_flush_size=32 (new: how many pages to flush on LRU eviction) innodb_lru_scan_depth=1536 (old: 1024) innodb_max_dirty_pages_pct=90 (old: 75) innodb_max_dirty_pages_pct_lwm=75 (old: 0) Note: The parameter innodb_lru_scan_depth will only affect LRU eviction of buffer pool pages when a new page is being allocated. The page cleaner thread will no longer evict any pages. It used to guarantee that some pages will remain free in the buffer pool. Now, we perform that eviction 'on demand' in buf_LRU_get_free_block(). The parameter innodb_lru_scan_depth(srv_LRU_scan_depth) is used as follows: * When the buffer pool is being shrunk in buf_pool_t::withdraw_blocks() * As a buf_pool.free limit in buf_LRU_list_batch() for terminating the flushing that is initiated e.g., by buf_LRU_get_free_block() The parameter also used to serve as an initial limit for unzip_LRU eviction (evicting uncompressed page frames while retaining ROW_FORMAT=COMPRESSED pages), but now we will use a hard-coded limit of 100 or unlimited for invoking buf_LRU_scan_and_free_block(). The status variables will be changed as follows: innodb_buffer_pool_pages_flushed: This includes also the count of innodb_buffer_pool_pages_LRU_flushed and should work reliably, updated one by one in buf_flush_page() to give more real-time statistics. The function buf_flush_stats(), which we are removing, was not called in every code path. For both counters, we will use regular variables that are incremented in a critical section of buf_pool.mutex. Note that show_innodb_vars() directly links to the variables, and reads of the counters will *not* be protected by buf_pool.mutex, so you cannot get a consistent snapshot of both variables. The following INFORMATION_SCHEMA.INNODB_METRICS counters will be removed, because the page cleaner no longer deals with writing or evicting least recently used pages, and because the single-page writes have been removed: * buffer_LRU_batch_flush_avg_time_slot * buffer_LRU_batch_flush_avg_time_thread * buffer_LRU_batch_flush_avg_time_est * buffer_LRU_batch_flush_avg_pass * buffer_LRU_single_flush_scanned * buffer_LRU_single_flush_num_scan * buffer_LRU_single_flush_scanned_per_call When moving to a single buffer pool instance in MDEV-15058, we missed some opportunity to simplify the buf_flush_page_cleaner thread. It was unnecessarily using a mutex and some complex data structures, even though we always have a single page cleaner thread. Furthermore, the buf_flush_page_cleaner thread had separate 'recovery' and 'shutdown' modes where it was waiting to be triggered by some other thread, adding unnecessary latency and potential for hangs in relatively rarely executed startup or shutdown code. The page cleaner was also running two kinds of batches in an interleaved fashion: "LRU flush" (writing out some least recently used pages and evicting them on write completion) and the normal batches that aim to increase the MIN(oldest_modification) in the buffer pool, to help the log checkpoint advance. The buf_pool.flush_list flushing was being blocked by buf_block_t::lock for no good reason. Furthermore, if the FIL_PAGE_LSN of a page is ahead of log_sys.get_flushed_lsn(), that is, what has been persistently written to the redo log, we would trigger a log flush and then resume the page flushing. This would unnecessarily limit the performance of the page cleaner thread and trigger the infamous messages "InnoDB: page_cleaner: 1000ms intended loop took 4450ms. The settings might not be optimal" that were suppressed in commit d1ab89037a518fcffbc50c24e4bd94e4ec33aed0 unless log_warnings>2. Our revised algorithm will make log_sys.get_flushed_lsn() advance at the start of buf_flush_lists(), and then execute a 'best effort' to write out all pages. The flush batches will skip pages that were modified since the log was written, or are are currently exclusively locked. The MDEV-13670 message "page_cleaner: 1000ms intended loop took" message will be removed, because by design, the buf_flush_page_cleaner() should not be blocked during a batch for extended periods of time. We will remove the single-page flushing altogether. Related to this, the debug parameter innodb_doublewrite_batch_size will be removed, because all of the doublewrite buffer will be used for flushing batches. If a page needs to be evicted from the buffer pool and all 100 least recently used pages in the buffer pool have unflushed changes, buf_LRU_get_free_block() will execute buf_flush_lists() to write out and evict innodb_lru_flush_size pages. At most one thread will execute buf_flush_lists() in buf_LRU_get_free_block(); other threads will wait for that LRU flushing batch to finish. To improve concurrency, we will replace the InnoDB ib_mutex_t and os_event_t native mutexes and condition variables in this area of code. Most notably, this means that the buffer pool mutex (buf_pool.mutex) is no longer instrumented via any InnoDB interfaces. It will continue to be instrumented via PERFORMANCE_SCHEMA. For now, both buf_pool.flush_list_mutex and buf_pool.mutex will be declared with MY_MUTEX_INIT_FAST (PTHREAD_MUTEX_ADAPTIVE_NP). The critical sections of buf_pool.flush_list_mutex should be shorter than those for buf_pool.mutex, because in the worst case, they cover a linear scan of buf_pool.flush_list, while the worst case of a critical section of buf_pool.mutex covers a linear scan of the potentially much longer buf_pool.LRU list. mysql_mutex_is_owner(), safe_mutex_is_owner(): New predicate, usable with SAFE_MUTEX. Some InnoDB debug assertions need this predicate instead of mysql_mutex_assert_owner() or mysql_mutex_assert_not_owner(). buf_pool_t::n_flush_LRU, buf_pool_t::n_flush_list: Replaces buf_pool_t::init_flush[] and buf_pool_t::n_flush[]. The number of active flush operations. buf_pool_t::mutex, buf_pool_t::flush_list_mutex: Use mysql_mutex_t instead of ib_mutex_t, to have native mutexes with PERFORMANCE_SCHEMA and SAFE_MUTEX instrumentation. buf_pool_t::done_flush_LRU: Condition variable for !n_flush_LRU. buf_pool_t::done_flush_list: Condition variable for !n_flush_list. buf_pool_t::do_flush_list: Condition variable to wake up the buf_flush_page_cleaner when a log checkpoint needs to be written or the server is being shut down. Replaces buf_flush_event. We will keep using timed waits (the page cleaner thread will wake _at least_ once per second), because the calculations for innodb_adaptive_flushing depend on fixed time intervals. buf_dblwr: Allocate statically, and move all code to member functions. Use a native mutex and condition variable. Remove code to deal with single-page flushing. buf_dblwr_check_block(): Make the check debug-only. We were spending a significant amount of execution time in page_simple_validate_new(). flush_counters_t::unzip_LRU_evicted: Remove. IORequest: Make more members const. FIXME: m_fil_node should be removed. buf_flush_sync_lsn: Protect by std::atomic, not page_cleaner.mutex (which we are removing). page_cleaner_slot_t, page_cleaner_t: Remove many redundant members. pc_request_flush_slot(): Replaces pc_request() and pc_flush_slot(). recv_writer_thread: Remove. Recovery works just fine without it, if we simply invoke buf_flush_sync() at the end of each batch in recv_sys_t::apply(). recv_recovery_from_checkpoint_finish(): Remove. We can simply call recv_sys.debug_free() directly. srv_started_redo: Replaces srv_start_state. SRV_SHUTDOWN_FLUSH_PHASE: Remove. logs_empty_and_mark_files_at_shutdown() can communicate with the normal page cleaner loop via the new function flush_buffer_pool(). buf_flush_remove(): Assert that the calling thread is holding buf_pool.flush_list_mutex. This removes unnecessary mutex operations from buf_flush_remove_pages() and buf_flush_dirty_pages(), which replace buf_LRU_flush_or_remove_pages(). buf_flush_lists(): Renamed from buf_flush_batch(), with simplified interface. Return the number of flushed pages. Clarified comments and renamed min_n to max_n. Identify LRU batch by lsn=0. Merge all the functions buf_flush_start(), buf_flush_batch(), buf_flush_end() directly to this function, which was their only caller, and remove 2 unnecessary buf_pool.mutex release/re-acquisition that we used to perform around the buf_flush_batch() call. At the start, if not all log has been durably written, wait for a background task to do it, or start a new task to do it. This allows the log write to run concurrently with our page flushing batch. Any pages that were skipped due to too recent FIL_PAGE_LSN or due to them being latched by a writer should be flushed during the next batch, unless there are further modifications to those pages. It is possible that a page that we must flush due to small oldest_modification also carries a recent FIL_PAGE_LSN or is being constantly modified. In the worst case, all writers would then end up waiting in log_free_check() to allow the flushing and the checkpoint to complete. buf_do_flush_list_batch(): Clarify comments, and rename min_n to max_n. Cache the last looked up tablespace. If neighbor flushing is not applicable, invoke buf_flush_page() directly, avoiding a page lookup in between. buf_flush_space(): Auxiliary function to look up a tablespace for page flushing. buf_flush_page(): Defer the computation of space->full_crc32(). Never call log_write_up_to(), but instead skip persistent pages whose latest modification (FIL_PAGE_LSN) is newer than the redo log. Also skip pages on which we cannot acquire a shared latch without waiting. buf_flush_try_neighbors(): Do not bother checking buf_fix_count because buf_flush_page() will no longer wait for the page latch. Take the tablespace as a parameter, and only execute this function when innodb_flush_neighbors>0. Avoid repeated calls of page_id_t::fold(). buf_flush_relocate_on_flush_list(): Declare as cold, and push down a condition from the callers. buf_flush_check_neighbor(): Take id.fold() as a parameter. buf_flush_sync(): Ensure that the buf_pool.flush_list is empty, because the flushing batch will skip pages whose modifications have not yet been written to the log or were latched for modification. buf_free_from_unzip_LRU_list_batch(): Remove redundant local variables. buf_flush_LRU_list_batch(): Let the caller buf_do_LRU_batch() initialize the counters, and report n->evicted. Cache the last looked up tablespace. If neighbor flushing is not applicable, invoke buf_flush_page() directly, avoiding a page lookup in between. buf_do_LRU_batch(): Return the number of pages flushed. buf_LRU_free_page(): Only release and re-acquire buf_pool.mutex if adaptive hash index entries are pointing to the block. buf_LRU_get_free_block(): Do not wake up the page cleaner, because it will no longer perform any useful work for us, and we do not want it to compete for I/O while buf_flush_lists(innodb_lru_flush_size, 0) writes out and evicts at most innodb_lru_flush_size pages. (The function buf_do_LRU_batch() may complete after writing fewer pages if more than innodb_lru_scan_depth pages end up in buf_pool.free list.) Eliminate some mutex release-acquire cycles, and wait for the LRU flush batch to complete before rescanning. buf_LRU_check_size_of_non_data_objects(): Simplify the code. buf_page_write_complete(): Remove the parameter evict, and always evict pages that were part of an LRU flush. buf_page_create(): Take a pre-allocated page as a parameter. buf_pool_t::free_block(): Free a pre-allocated block. recv_sys_t::recover_low(), recv_sys_t::apply(): Preallocate the block while not holding recv_sys.mutex. During page allocation, we may initiate a page flush, which in turn may initiate a log flush, which would require acquiring log_sys.mutex, which should always be acquired before recv_sys.mutex in order to avoid deadlocks. Therefore, we must not be holding recv_sys.mutex while allocating a buffer pool block. BtrBulk::logFreeCheck(): Skip a redundant condition. row_undo_step(): Do not invoke srv_inc_activity_count() for every row that is being rolled back. It should suffice to invoke the function in trx_flush_log_if_needed() during trx_t::commit_in_memory() when the rollback completes. sync_check_enable(): Remove. We will enable innodb_sync_debug from the very beginning.

Invoking buf_page_get_gen() in a read completion function is a definite no-no, because it could trigger a page flush or cause the server to run out of buffer pool.

This caused handle_alter_part_error() to try to close already closed tables, which caused the crash. Fixed fast_alter_partion_table() to reflect when tables are opened. I also fixed that ha_partition::change_partitions() resets m_new_file in case of errors.

It is now done by a new class JSON. modified: storage/connect/json.cpp modified: storage/connect/json.h - Add a new UDF function jfile_translate. It translate a Json file to pretty = 0. Fast because it does not a real parse of the file. modified: storage/connect/jsonudf.cpp modified: storage/connect/jsonudf.h - Add a now options JSIZE and STRINGIFY to Json tables. STRINGIFY makes Objects or Arrays to be returned by their json representation instead of by their concatenated values. JSIZE allows to specify the LRECL (was 256) defaults to 1024.

charset=UTF-8 Content-Transfer-Encoding: 8bit Problem: ======= InnoDB allows virtual index to be referenced index in foreign key relations. While dropping the virtual column, Inplace alter does allow the table to be closed and open it using table name to update dict_table_t::v_cols. While loading the table, it doesn't allow any error to be ignored. InnoDB can't find the referenced virtual index and fails to load the table during Inplace alter. Solution: ========= During inplace alter, ignore the foreign key error while loading the table.

It is NULL-row of xtitle for complementing the join and the above comparisons of course FALSE, but trigcond (Item_func_trig_cond) makes them TRUE via its trig_var property which is bound to some boolean properties of JOIN_TAB. Expression (2) evaluated to TRUE because its trig_var is bound to first_inner_tab->not_null_compl. The expression (1) does not evaluate correctly because row_end comparison's trig_var is bound to first_inner->found earlier. As a result JOIN_CACHE::check_match() skipped the row for join_null_complements(). When we add versioning condition to table's on_expr the optimizer in make_join_select() distributes conditions differently. tmp_cond inherits on_expr value and in Good case it is full expression xgender.elementId = x.`id` and xgender.pkey = 'gender' and xgender.row_end = TIMESTAMP'2038-01-19 06:14:07.999999' while in Bad case it is only xgender.elementId = x.`id` and xgender.pkey = 'gender'. Later in Good row_end condition is optimized out and we get one trigcond in form of (2). --- mysql-test/suite/versioning/r/select.result | 21 +++++++++++++++++++++ mysql-test/suite/versioning/t/select.test | 21 +++++++++++++++++++++ sql/sql_select.cc | 1 + 3 files changed, 43 insertions(+) diff --git a/mysql-test/suite/versioning/r/select.result b/mysql-test/suite/versioning/r/select.result index 23c6e2d74af..00e257a576f 100644 --- a/mysql-test/suite/versioning/r/select.result +++ b/mysql-test/suite/versioning/r/select.result @@ -609,6 +609,27 @@ ERROR 22007: Incorrect date value: 'foo' for column `test`.`t2`.`b` at row 1 drop prepare stmt; drop procedure pr; drop table t1, t2; +# +# MDEV-23799 CREATE ..

When VIEW is queried both clauses PARTITION and FOR SYSTEM_TIME ALL lead to ER_VERS_QUERY_IN_PARTITION (same place WITH_PARTITION_STORAGE_ENGINE). Fix removes FOR SYSTEM_TIME ALL from VIEW by accessing original SYSTEM_TIME clause: the one specified in parser.

Because the call is not protected by LatchCounter::m_mutex, any mutex_create() or mutex_free() that is invoked concurrently during the execution, bad things such as a crash could happen. The most likely way for this to happen is buffer pool resizing, which could cause buf_block_t::mutex (which existed before MDEV-15053) to be created or freed. We could also register InnoDB mutexes in TrxFactory::init() if trx_pools needs to grow. The view INFORMATION_SCHEMA.INNODB_MUTEXES is not affected, because it only displays information about rw-locks, not mutexes. This commit intentionally touches also MutexMonitor::iterate() and the only code that interfaces with LatchCounter::iterate() to make it clearer for future readers that the scattered code that is obfuscated by templates belongs together.

This race condition would be fixed by always acquiring an InnoDB table lock in ha_innobase::prepare_inplace_alter_table() or prepare_inplace_alter_table_dict(), or by ensuring that recovered transactions are protected by MDL that would block concurrent DDL until the rollback has been completed.

It also fixes all failing replication S3 tests. A slave is delayed if it is trying to execute replicated queries on a table that is already converted to S3 by the master later in the binlog. Fixes for replication events on S3 tables for delayed slaves: - INSERT and INSERT ... SELECT and CREATE TABLE are ignored but written to the binary log. UPDATE & DELETE will be fixed in a future commit. Other things: - On slaves with --s3-slave-ignore-updates set, allow S3 tables to be opened in read-write mode. This was done to be able to ignore-but-replicate queries like insert. Without this change any open of an S3 table failed with 'Table is read only' which is too early to be able to replicate the original query. - Errors are now printed if handler::extra() call fails in wait_while_tables_are_used(). - Error message for row changes are changed from HA_ERR_WRONG_COMMAND to HA_ERR_TABLE_READONLY. - Disable some maria_extra() calls for S3 tables. This could cause S3 tables to fail in some cases. - Added missing thr_lock_delete() to ma_open() in case of failure. - Removed from mysql_prepare_insert() the not needed argument 'table'. --- mysql-test/suite/s3/alter.result | 8 ++ mysql-test/suite/s3/alter.test | 4 + mysql-test/suite/s3/partition.result | 2 +- mysql-test/suite/s3/replication.inc | 10 +- mysql-test/suite/s3/replication_delayed.cnf | 3 + .../suite/s3/replication_delayed.result | 124 ++++++++++++++++++ mysql-test/suite/s3/replication_delayed.test | 115 ++++++++++++++++ mysql-test/suite/s3/replication_mixed.result | 27 +++- mysql-test/suite/s3/replication_stmt.result | 27 +++- sql/handler.cc | 9 +- sql/log.cc | 6 + sql/sql_base.cc | 13 +- sql/sql_class.cc | 32 +++++ sql/sql_class.h | 1 + sql/sql_insert.cc | 92 +++++++------ sql/sql_insert.h | 10 +- sql/sql_parse.cc | 8 ++ sql/sql_parse.h | 2 +- sql/sql_prepare.cc | 5 +- sql/sql_table.cc | 69 +++++++++- storage/maria/ha_s3.cc | 22 +++- storage/maria/ha_s3.h | 12 +- storage/maria/ma_extra.c | 15 ++- storage/maria/ma_open.c | 5 + 24 files changed, 539 insertions(+), 82 deletions(-) create mode 100644 mysql-test/suite/s3/replication_delayed.cnf create mode 100644 mysql-test/suite/s3/replication_delayed.result create mode 100644 mysql-test/suite/s3/replication_delayed.test diff --git a/mysql-test/suite/s3/alter.result b/mysql-test/suite/s3/alter.result index 0764d661468..da9ddb11ea7 100644 --- a/mysql-test/suite/s3/alter.result +++ b/mysql-test/suite/s3/alter.result @@ -25,6 +25,14 @@ t1 CREATE TABLE `t1` ( `a` int(11) DEFAULT NULL, `b` int(11) DEFAULT NULL ) ENGINE=Aria DEFAULT CHARSET=latin1 PAGE_CHECKSUM=1 COMMENT='hello' +alter table t1 engine=s3;

This caused crashes in ha_maria::extra() as the maria handler was called on files that was already closed. - In ma_pagecache there was a bug that when one got a read error one a big block (s3 block), it left the flag PCBLOCK_BIG_READ on for the page which cased an assert when the page where flushed. - Flush all cached tables in case of ignored ALTER TABLE Note that when merging code from 10.3, that fixes the partition bug, use the code from this patch instead.

However, in order for the MDEV-23199 logic to work, changes of FSP_SPACE_FLAGS must always be written in full (mtr_t::FORCED), so that crash recovery can parse them. We must know the flags in advance, because we might be applying log to other pages than page 0 first. recv_scan_log_recs(): Correct a misleading message about starting crash recovery. Display both the checkpoint LSN and the start of the records that end in the FILE_CHECKPOINT marker.

Without this, it could be the case (as was on OSX) that a flag was never checked in CHECK_CXX_SOURCE_COMPILES, the CHECK successfully passed, but failed at link time. As such we use CMAKE_REQUIRED_LIBRARIES to include the flags to check as its compatible enough with the cmake versions for non-Windows compilers/linkers.

Thus the testcase has a race condition where the initial replication setup might finish executing later than the testcase SET GLOBAL init_slave, making the testcase see its effect where it checks for its absence. Fix: === Include 'sync_slave_sql_with_master.inc' at the beginning of the test to ensure that slave applier has completed the execution of 'init_slave' command and proceeded to event application. Replace the apparently needless RESET MASTER / RESET SLAVE etc. Patch is based on: https://github.com/percona/percona-server/pull/1464/commits/b91e2e6f90611aa299c302929fb8b068e8ac0dee Author: laurynas-biveinis --- .../sys_vars/r/rpl_init_slave_func.result | 15 +++------ .../suite/sys_vars/t/rpl_init_slave_func.test | 33 ++++++++++--------- 2 files changed, 21 insertions(+), 27 deletions(-) diff --git a/mysql-test/suite/sys_vars/r/rpl_init_slave_func.result b/mysql-test/suite/sys_vars/r/rpl_init_slave_func.result index 691f6f10e02..d63a540fe15 100644 --- a/mysql-test/suite/sys_vars/r/rpl_init_slave_func.result +++ b/mysql-test/suite/sys_vars/r/rpl_init_slave_func.result @@ -1,6 +1,6 @@ include/master-slave.inc [connection master] -connection slave +include/sync_slave_sql_with_master.inc SET @start_max_connections= @@global.max_connections; SET @start_init_slave= @@global.init_slave; SET NAMES utf8; @@ -19,18 +19,11 @@ SELECT @@global.init_slave = 'SET @@global.max_connections = @@global.max_connec 1 Expect 1 include/assert.inc [@@global.max_connections = @start_max_connections] -STOP SLAVE; -RESET MASTER; -RESET SLAVE; -START SLAVE; -include/wait_for_slave_to_start.inc +include/restart_slave.inc +include/sync_slave_sql_with_master.inc include/assert.inc [@@global.max_connections = @start_max_connections + 1] SET @@global.init_slave = "SET @a=5"; -STOP SLAVE; -RESET MASTER; -RESET SLAVE; -START SLAVE; -include/wait_for_slave_to_start.inc +include/restart_slave.inc SHOW VARIABLES LIKE 'init_slave'; Variable_name Value init_slave SET @a=5 diff --git a/mysql-test/suite/sys_vars/t/rpl_init_slave_func.test b/mysql-test/suite/sys_vars/t/rpl_init_slave_func.test index 1d57bfeddc5..0e5ff7a3f39 100644 --- a/mysql-test/suite/sys_vars/t/rpl_init_slave_func.test +++ b/mysql-test/suite/sys_vars/t/rpl_init_slave_func.test @@ -29,8 +29,13 @@ ############################################################################### source include/master-slave.inc; ---echo connection slave -connection slave; + +# Since a part of slave SQL thread initialisation happens after Slave_SQL_Running +# has been set to Yes, there is a race condition between initialisation above and +# init_slave setting given below.

AddressSanitizer would trip when writing undo log for an INSERT operation that follows the problematic ALTER TABLE because the v_indexes would refer to an index object that was freed during the execution of ALTER TABLE. The operation to remove NOT NULL attribute from a column should lead into any affected indexes to be dropped and re-created. But, the SQL layer set the ha_alter_info->handler_flags to HA_INPLACE_ADD_UNIQUE_INDEX_NO_WRITE|ALTER_COLUMN_NULLABLE (that is, InnoDB was asked to add an index and change the column, but not to drop the index that depended on the column). Let us restore the debug assertion that catches this problem outside AddressSanitizer, and 'defuse' the offending ALTER TABLE statement in the test until something has been fixed in the SQL layer. --- mysql-test/suite/innodb/r/instant_alter_bugs.result | 6 ++---- mysql-test/suite/innodb/t/instant_alter_bugs.test | 10 ++++++---- storage/innobase/handler/handler0alter.cc | 1 + 3 files changed, 9 insertions(+), 8 deletions(-) diff --git a/mysql-test/suite/innodb/r/instant_alter_bugs.result b/mysql-test/suite/innodb/r/instant_alter_bugs.result index 45172be8593..473ee1926da 100644 --- a/mysql-test/suite/innodb/r/instant_alter_bugs.result +++ b/mysql-test/suite/innodb/r/instant_alter_bugs.result @@ -422,11 +422,9 @@ col_text text not null, col_int_g integer generated always as (col_int) unique, col_text_g text generated always as (substr(col_text,1,499)) ) engine innodb row_format = redundant;

When such tablespace is tried to be opened during prepare in xb_delta_open_matching_space(), it is "created", i.e. xb_space_create_file() is invoked, instead of opening, even if a tablespace with the same name exists in the base backup directory. xb_space_create_file() writes page 0 header the tablespace. This header does not contain crypt data, as mariabackup does not have any information about crypt data in delta file metadata for tablespaces. After delta file is applied, recovery process is started. As the sequence of recovery for different pages is not defined, there can be the situation when crypt data redo log event is executed after some other page is read for recovery. When some page is read for recovery, it's decrypted using crypt data stored in tablespace header in page 0, if there is no crypt data, the page is not decryped and does not pass corruption test. This causes error for incremental backup --prepare for encrypted tablespaces. The error is not stable because crypt data redo log event updates crypt data on page 0, and recovery for different pages can be executed in undefined order. The fix: When delta file is created, the corresponding write filter copies only the pages which LSN is greater then some incremental LSN. When new file is created during incremental backup, the LSN of all it's pages must be greater then incremental LSN, so there is no need to create delta for such table, we can just copy it completely. The fix is to copy the whole file which was tracked during incremental backup with innodb ddl tracker, and copy it to base directory during --prepare instead of delta applying. There is also DBUG_EXECUTE_IF() in innodb code to avoid writing redo log record for crypt data updating on page 0 to make the test case stable. Note: The issue is not reproducible in 10.5 as optimized DDL's are deprecated in 10.5. But the fix is still useful because it allows to decrease data copy size during backup, as delta file contains some extra info. The test case should be removed for 10.5 as it will always pass. --- extra/mariabackup/xtrabackup.cc | 153 ++++++++++++------ .../mariabackup/ddl_incremental_encrypted.opt | 7 + .../ddl_incremental_encrypted.result | 26 +++ .../ddl_incremental_encrypted.test | 66 ++++++++ storage/innobase/fil/fil0crypt.cc | 2 + 5 files changed, 203 insertions(+), 51 deletions(-) create mode 100644 mysql-test/suite/mariabackup/ddl_incremental_encrypted.opt create mode 100644 mysql-test/suite/mariabackup/ddl_incremental_encrypted.result create mode 100644 mysql-test/suite/mariabackup/ddl_incremental_encrypted.test diff --git a/extra/mariabackup/xtrabackup.cc b/extra/mariabackup/xtrabackup.cc index 7cb9d5ac3fe..668a355f0fa 100644 --- a/extra/mariabackup/xtrabackup.cc +++ b/extra/mariabackup/xtrabackup.cc @@ -2537,17 +2537,24 @@ xb_get_copy_action(const char *dflt) return(action); } -/* TODO: We may tune the behavior (e.g. by fil_aio)*/ -static -my_bool -xtrabackup_copy_datafile(fil_node_t* node, uint thread_n, const char *dest_name=0, ulonglong max_size=ULLONG_MAX) +/** Copy innodb data file to the specified destination. + +@param[in] node file node of a tablespace +@param[in] thread_n thread id, used in the text of diagnostic messages +@param[in] dest_name destination file name +@param[in] write_filter write filter to copy data, can be pass-through filter +for full backup, pages filter for incremental backup, etc. + +@return FALSE on success and TRUE on error */ +static my_bool xtrabackup_copy_datafile(fil_node_t *node, uint thread_n, + const char *dest_name, + const xb_write_filt_t &write_filter) { char dst_name[FN_REFLEN]; ds_file_t *dstfile = NULL; xb_fil_cur_t cursor; xb_fil_cur_result_t res; - xb_write_filt_t *write_filter = NULL; xb_write_filt_ctxt_t write_filt_ctxt; const char *action; xb_read_filt_t *read_filter; @@ -2587,7 +2594,7 @@ xtrabackup_copy_datafile(fil_node_t* node, uint thread_n, const char *dest_name= read_filter = &rf_bitmap; } - res = xb_fil_cur_open(&cursor, read_filter, node, thread_n,max_size); + res = xb_fil_cur_open(&cursor, read_filter, node, thread_n, ULLONG_MAX); if (res == XB_FIL_CUR_SKIP) { goto skip; } else if (res == XB_FIL_CUR_ERROR) { @@ -2598,18 +2605,11 @@ xtrabackup_copy_datafile(fil_node_t* node, uint thread_n, const char *dest_name= sizeof dst_name - 1); dst_name[sizeof dst_name - 1] = '\0'; - /* Setup the page write filter */ - if (xtrabackup_incremental) { - write_filter = &wf_incremental; - } else { - write_filter = &wf_write_through; - } - memset(&write_filt_ctxt, 0, sizeof(xb_write_filt_ctxt_t)); - ut_a(write_filter->process != NULL); + ut_a(write_filter.process != NULL); - if (write_filter->init != NULL && - !write_filter->init(&write_filt_ctxt, dst_name, &cursor)) { + if (write_filter.init != NULL && + !write_filter.init(&write_filt_ctxt, dst_name, &cursor)) { msg (thread_n, "mariabackup: error: failed to initialize page write filter."); goto error; } @@ -2630,7 +2630,7 @@ xtrabackup_copy_datafile(fil_node_t* node, uint thread_n, const char *dest_name= /* The main copy loop */ while ((res = xb_fil_cur_read(&cursor)) == XB_FIL_CUR_SUCCESS) { - if (!write_filter->process(&write_filt_ctxt, dstfile)) { + if (!write_filter.process(&write_filt_ctxt, dstfile)) { goto error; } } @@ -2639,8 +2639,8 @@ xtrabackup_copy_datafile(fil_node_t* node, uint thread_n, const char *dest_name= goto error; } - if (write_filter->finalize - && !write_filter->finalize(&write_filt_ctxt, dstfile)) { + if (write_filter.finalize + && !write_filter.finalize(&write_filt_ctxt, dstfile)) { goto error; } @@ -2654,8 +2654,8 @@ xtrabackup_copy_datafile(fil_node_t* node, uint thread_n, const char *dest_name= if (ds_close(dstfile)) { rc = TRUE; } - if (write_filter && write_filter->deinit) { - write_filter->deinit(&write_filt_ctxt); + if (write_filter.deinit) { + write_filter.deinit(&write_filt_ctxt); } return(rc); @@ -2664,8 +2664,8 @@ error: if (dstfile != NULL) { ds_close(dstfile); } - if (write_filter && write_filter->deinit) { - write_filter->deinit(&write_filt_ctxt);; + if (write_filter.deinit) { + write_filter.deinit(&write_filt_ctxt);; } msg(thread_n, "mariabackup: xtrabackup_copy_datafile() failed."); return(TRUE); /*ERROR*/ @@ -2675,8 +2675,8 @@ skip: if (dstfile != NULL) { ds_close(dstfile); } - if (write_filter && write_filter->deinit) { - write_filter->deinit(&write_filt_ctxt); + if (write_filter.deinit) { + write_filter.deinit(&write_filt_ctxt); } msg(thread_n,"Warning: We assume the table was dropped during xtrabackup execution and ignore the tablespace %s", node_name); return(FALSE); @@ -2974,9 +2974,9 @@ data_copy_thread_func( while ((node = datafiles_iter_next(ctxt->it)) != NULL) { DBUG_MARIABACKUP_EVENT("before_copy", node->space->name); /* copy the datafile */ - if(xtrabackup_copy_datafile(node, num)) { + if (xtrabackup_copy_datafile(node, num, NULL, + xtrabackup_incremental ?

^ In case MariaDB server is build with -DCMAKE_BUILD_TYPE=Debug it results in build error. The reason of compiler warnings is that declaration of the Posix C API function getgrouplist() on MacOS differs from declaration of getgrouplist() proposed by Posix. To suppress this compiler warning cmake configure was adapted to detect what kind of getgrouplist() function is declared on the build platform and set the macros HAVE_POSIX_GETGROUPLIST in case the building platform supports Posix compatible interface for the getgrouplist() function. Depending on whether this macros is set the compatible type of arguments is used to pass parameter values to the function. --- plugin/auth_pam/CMakeLists.txt | 26 +++++++++++++++++++++++ plugin/auth_pam/mapper/pam_user_map.c | 30 +++++++++++++++++---------- 2 files changed, 45 insertions(+), 11 deletions(-) diff --git a/plugin/auth_pam/CMakeLists.txt b/plugin/auth_pam/CMakeLists.txt index ac598e4ffa6..fce9b8cf8a6 100644 --- a/plugin/auth_pam/CMakeLists.txt +++ b/plugin/auth_pam/CMakeLists.txt @@ -5,6 +5,30 @@ CHECK_INCLUDE_FILES (security/pam_ext.h HAVE_PAM_EXT_H) CHECK_INCLUDE_FILES (security/pam_appl.h HAVE_PAM_APPL_H) CHECK_FUNCTION_EXISTS (strndup HAVE_STRNDUP) +INCLUDE_DIRECTORIES(${CMAKE_CURRENT_BINARY_DIR}) + +# Check whether getgrouplist uses git_t for second and third arguments. +SET(CMAKE_REQUIRED_FLAGS -Werror) +CHECK_C_SOURCE_COMPILES( +" +#ifdef HAVE_GRP_H +#include +#endif +#ifdef HAVE_UNISTD_H +#include +#endif +int main() { + char *arg_1;

Replace all unused (not marked in read_set) columns in an I_S table with CHAR(0). This can drastically reduce the footprint of a MEMORY table (a TABLE_CATALOG alone is 1538 bytes per row). This does not change the engine. If the table was decided to be Aria (because of, say, blobs) then after optimization it'll stay Aria even if all blobs were removed. Note 1: when transforming table structure, share->blob_fields is preserved, otherwise Aria might switch from DYNAMIC to STATIC row format and expect a special field for a deleted mark, which create_tmp_tabe didn't provide. Note 2: optimizer was doing handler::info() (to know the number of rows) before the temp table is populated. That didn't make much sense. Now it's done before the table is even instantiated. Preserve the old behavior and report 0 rows.

An IO_CACHE that uses encryption uses a larger buffer (it needs space for the encrypted data, decrypted data, IO_CACHE_CRYPT struct to describe encryption parameters etc). Issue #2: IO_CACHE::seek_not_done When IO_CACHE objects are cloned, they still share the file descriptor. This means, operation on one IO_CACHE may change the file read position which will confuse other IO_CACHEs using it. The fix of these issues would be: Allocate the buffer to also include the extra size needed for encryption.

In MDEV-16809 we introduced a parameter that allows the redo log to be written, so that Mariabackup would not be impacted, but we kept the MySQL 5.7 behaviour enabled by default (innodb_log_optimize_ddl=ON). As noted in MDEV-19747 (Deprecate and ignore innodb_log_optimize_ddl, implemented in MariaDB 10.5.1), omitting the redo log writes can actually reduce performance, because we will have to wait for the data pages to be written out. When the redo log file is configured to be large enough, it actually can be much faster to write the redo log and avoid the extra page flushing. When the redo log is omitted (innodb_log_optimize_ddl=ON), also Mariabackup may have to perform a lot of extra work, to re-copy the entire data file if it is possible that any log was omitted during the backup. Starting with MariaDB 10.5.1, the parameter innodb_log_optimize_ddl is deprecated and ignored. We hereby deprecate (but will not ignore) the parameter in earlier versions as well. --- mysql-test/suite/mariabackup/mlog_index_load.result | 1 + mysql-test/suite/mariabackup/mlog_index_load.test | 1 + mysql-test/suite/sys_vars/r/sysvars_innodb.result | 4 ++-- storage/innobase/handler/ha_innodb.cc | 8 ++++---- 4 files changed, 8 insertions(+), 6 deletions(-) diff --git a/mysql-test/suite/mariabackup/mlog_index_load.result b/mysql-test/suite/mariabackup/mlog_index_load.result index bc83981106e..8925e897399 100644 --- a/mysql-test/suite/mariabackup/mlog_index_load.result +++ b/mysql-test/suite/mariabackup/mlog_index_load.result @@ -1,5 +1,6 @@ CREATE TABLE t1(i INT PRIMARY KEY auto_increment, a int) ENGINE INNODB; INSERT INTO t1(a) SELECT * from seq_1_to_10000; +SET GLOBAL innodb_log_optimize_ddl=ON; # xtrabackup backup t1.frm t1.ibd diff --git a/mysql-test/suite/mariabackup/mlog_index_load.test b/mysql-test/suite/mariabackup/mlog_index_load.test index fb29041fd3c..b9fd6f8ca32 100644 --- a/mysql-test/suite/mariabackup/mlog_index_load.test +++ b/mysql-test/suite/mariabackup/mlog_index_load.test @@ -2,6 +2,7 @@ CREATE TABLE t1(i INT PRIMARY KEY auto_increment, a int) ENGINE INNODB; INSERT INTO t1(a) SELECT * from seq_1_to_10000; +SET GLOBAL innodb_log_optimize_ddl=ON; let $targetdir=$MYSQLTEST_VARDIR/tmp/backup; diff --git a/mysql-test/suite/sys_vars/r/sysvars_innodb.result b/mysql-test/suite/sys_vars/r/sysvars_innodb.result index bed23a777a8..d3d30f8f53f 100644 --- a/mysql-test/suite/sys_vars/r/sysvars_innodb.result +++ b/mysql-test/suite/sys_vars/r/sysvars_innodb.result @@ -1568,10 +1568,10 @@ READ_ONLY YES COMMAND_LINE_ARGUMENT REQUIRED VARIABLE_NAME INNODB_LOG_OPTIMIZE_DDL SESSION_VALUE NULL -DEFAULT_VALUE ON +DEFAULT_VALUE OFF VARIABLE_SCOPE GLOBAL VARIABLE_TYPE BOOLEAN -VARIABLE_COMMENT Reduce redo logging when natively creating indexes or rebuilding tables.

InnoDB would always zip_pad_info_t::mutex and dict_table_t::autoinc_mutex, even for tables are not in ROW_FORMAT=COMPRESSED nor include any AUTO_INCREMENT column. --- storage/innobase/dict/dict0dict.cc | 150 +++------------------------ storage/innobase/dict/dict0mem.cc | 42 ++++---- storage/innobase/dict/dict0stats.cc | 10 +- storage/innobase/ibuf/ibuf0ibuf.cc | 2 +- storage/innobase/include/dict0dict.h | 25 +---- storage/innobase/include/dict0mem.h | 118 ++++----------------- storage/innobase/include/os0once.h | 118 --------------------- storage/innobase/page/page0zip.cc | 2 +- 8 files changed, 68 insertions(+), 399 deletions(-) delete mode 100644 storage/innobase/include/os0once.h diff --git a/storage/innobase/dict/dict0dict.cc b/storage/innobase/dict/dict0dict.cc index ba0cb9e4d4e..37a8a4387d1 100644 --- a/storage/innobase/dict/dict0dict.cc +++ b/storage/innobase/dict/dict0dict.cc @@ -60,7 +60,6 @@ extern uint ibuf_debug;

The server terminates abnormally when phrase search doesn't filter out doc_ids correctly. This problem has been fixed in bug 2. Wrong query result: It's a regression from the bug #22709692 fix. This fix optimize full-text search query with limit clause. when FTS expression involves only union operation, we fetch only number of doc_ids specified with the limit clause. Fulltext phrase search is not an union operation and we consider phrase search with plugin parser a union operation. In phrase search with limit clause, we fetch limited doc_ids for each token and if any of the selected doc_id does not contain all tokens in correct order then we do not include that row_id in the result set. Therefore phrase search gets fewer number of rows than the qualified rows exist in the table. Fix: Added a condition that phrase search with plugin parser is not a union operation.

If innodb_io_capacity is set low or innodb_max_dirty_pct_lwm is set high and the workload fits in the buffer pool, the page cleaner thread will perform very little flushing. When we reach the capacity of the circular redo log file ib_logfile0 and must initiate a checkpoint, some 'furious flushing' will be necessary. (If innodb_flush_sync=OFF, then flushing would continue at the innodb_io_capacity rate, and writers would be throttled.) We have the best chance of advancing the checkpoint LSN immediately after a page flush batch has been completed. Hence, it is best to perform checkpoints after every batch in the page cleaner thread, attempting to run once per second. By initiating high-priority flushing in the page cleaner as early as possible, we aim to make the throughput more stable. The function buf_flush_wait_flushed() used to sleep for 10ms, hoping that the page cleaner thread would do something during that time. The observed end result was that a large number of threads that call log_free_check() would end up sleeping while nothing useful is happening. We will revise the design so that in the default innodb_flush_sync=ON mode, buf_flush_wait_flushed() will wake up the page cleaner thread to perform the necessary flushing, and it will wait for a signal from the page cleaner thread. If innodb_io_capacity is set to a low value (causing the page cleaner to throttle its work), a write workload would initially perform well, until the capacity of the circular ib_logfile0 is reached and log_free_check() will trigger checkpoints. At that point, the extra waiting in buf_flush_wait_flushed() will start reducing throughput. The page cleaner thread will also initiate log checkpoints after each buf_flush_lists() call, because that is the best point of time for the checkpoint LSN to advance by the maximum amount. Even in 'furious flushing' mode we invoke buf_flush_lists() with innodb_io_capacity_max pages at a time, and at the start of each batch (in the log_flush() callback function that runs in a separate task) we will invoke os_aio_wait_until_no_pending_writes(). This tweak allows the checkpoint to advance in smaller steps and significantly reduces the maximum latency. On an Intel Optane 960 NVMe SSD on Linux, it reduced from 4.6 seconds to 74 milliseconds. On Microsoft Windows with a slower SSD, it reduced from more than 180 seconds to 0.6 seconds. We will make innodb_adaptive_flushing=OFF simply flush innodb_io_capacity per second whenever the dirty proportion of buffer pool pages exceeds innodb_max_dirty_pages_pct_lwm. For innodb_adaptive_flushing=ON we try to make page_cleaner_flush_pages_recommendation() more consistent and predictable: if we are below innodb_adaptive_flushing_lwm, let us flush pages according to the return value of af_get_pct_for_dirty(). innodb_max_dirty_pages_pct_lwm: Revert the change of the default value that was made in MDEV-23399. The value innodb_max_dirty_pages_pct_lwm=0 guarantees that a shutdown of an idle server will be fast. Users might be surprised if normal shutdown suddenly became slower when upgrading within a GA release series. innodb_checkpoint_usec: Remove. The master task will no longer perform periodic log checkpoints. It is the duty of the page cleaner thread. log_sys.max_modified_age: Remove. The current span of the buf_pool.flush_list expressed in LSN only matters for adaptive flushing (outside the 'furious flushing' condition). For the correctness of checkpoints, the only thing that matters is the checkpoint age (log_sys.lsn - log_sys.last_checkpoint_lsn). This run-time constant was also reported as log_max_modified_age_sync. log_sys.max_checkpoint_age_async: Remove. This does not serve any purpose, because the checkpoints will now be triggered by the page cleaner thread. We will retain the log_sys.max_checkpoint_age limit for engaging 'furious flushing'. page_cleaner.slot: Remove. It turns out that page_cleaner_slot.flush_list_time was duplicating page_cleaner.slot.flush_time and page_cleaner.slot.flush_list_pass was duplicating page_cleaner.flush_pass. Likewise, there were some redundant monitor counters, because the page cleaner thread no longer performs any buf_pool.LRU flushing, and because there only is one buf_flush_page_cleaner thread. buf_flush_sync_lsn: Protect writes by buf_pool.flush_list_mutex. buf_pool_t::get_oldest_modification(): Add a parameter to specify the return value when no persistent data pages are dirty. Require the caller to hold buf_pool.flush_list_mutex. log_buf_pool_get_oldest_modification(): Take the fall-back LSN as a parameter. All callers will also invoke log_sys.get_lsn(). log_preflush_pool_modified_pages(): Replaced with buf_flush_wait_flushed(). buf_flush_wait_flushed(): Implement two limits. If not enough buffer pool has been flushed, signal the page cleaner (unless innodb_flush_sync=OFF) and wait for the page cleaner to complete. If the page cleaner thread is not running (which can be the case durign shutdown), initiate the flush and wait for it directly. buf_flush_ahead(): If innodb_flush_sync=ON (the default), submit a new buf_flush_sync_lsn target for the page cleaner but do not wait for the flushing to finish. log_get_capacity(), log_get_max_modified_age_async(): Remove, to make it easier to see that af_get_pct_for_lsn() is not acquiring any mutexes. page_cleaner_flush_pages_recommendation(): Protect all access to buf_pool.flush_list with buf_pool.flush_list_mutex. Previously there were some race conditions in the calculation. buf_flush_sync_for_checkpoint(): New function to process buf_flush_sync_lsn in the page cleaner thread. At the end of each batch, we try to wake up any blocked buf_flush_wait_flushed(). If everything up to buf_flush_sync_lsn has been flushed, we will reset buf_flush_sync_lsn=0. The page cleaner thread will keep 'furious flushing' until the limit is reached. Any threads that are waiting in buf_flush_wait_flushed() will be able to resume as soon as their own limit has been satisfied. buf_flush_page_cleaner: Prioritize buf_flush_sync_lsn and do not sleep as long as it is set. Do not update any page_cleaner statistics for this special mode of operation. In the normal mode (buf_flush_sync_lsn is not set for innodb_flush_sync=ON), try to wake up once per second. No longer check whether srv_inc_activity_count() has been called. After each batch, try to perform a log checkpoint, because the best chances for the checkpoint LSN to advance by the maximum amount are upon completing a flushing batch. log_t: Move buf_free, max_buf_free possibly to the same cache line with log_sys.mutex. log_margin_checkpoint_age(): Simplify the logic, and replace a 0.1-second sleep with a call to buf_flush_wait_flushed() to initiate flushing. Moved to the same compilation unit with the only caller. log_close(): Clean up the calculations. (Should be no functional change.) Return whether flush-ahead is needed. Moved to the same compilation unit with the only caller. mtr_t::finish_write(): Return whether flush-ahead is needed. mtr_t::commit(): Invoke buf_flush_ahead() when needed. Let us avoid external calls in mtr_t::commit() and make the logic easier to follow by having related code in a single compilation unit. Also, we will invoke srv_stats.log_write_requests.inc() only once per mini-transaction commit, while not holding mutexes. log_checkpoint_margin(): Only care about log_sys.max_checkpoint_age. Upon reaching log_sys.max_checkpoint_age where we must wait to prevent the log from getting corrupted, let us wait for at most 1MiB of LSN at a time, before rechecking the condition. This should allow writers to proceed even if the redo log capacity has been reached and 'furious flushing' is in progress. We no longer care about log_sys.max_modified_age_sync or log_sys.max_modified_age_async. The log_sys.max_modified_age_sync could be a relic from the time when there was a srv_master_thread that wrote dirty pages to data files. Also, we no longer have any log_sys.max_checkpoint_age_async limit, because log checkpoints will now be triggered by the page cleaner thread upon completing buf_flush_lists(). log_set_capacity(): Simplify the calculations of the limit (no functional change). log_checkpoint_low(): Split from log_checkpoint(). Moved to the same compilation unit with the caller. log_make_checkpoint(): Only wait for everything to be flushed until the current LSN. create_log_file(): After checkpoint, invoke log_write_up_to() to ensure that the FILE_CHECKPOINT record has been written. This avoids ut_ad(!srv_log_file_created) in create_log_file_rename(). srv_start(): Do not call recv_recovery_from_checkpoint_start() if the log has just been created. Set fil_system.space_id_reuse_warned before dict_boot() has been executed, and clear it after recovery has finished. dict_boot(): Initialize fil_system.max_assigned_id. srv_check_activity(): Remove. The activity count is counting transaction commits and therefore mostly interesting for the purge of history. BtrBulk::insert(): Do not explicitly wake up the page cleaner, but do invoke srv_inc_activity_count(), because that counter is still being used in buf_load_throttle_if_needed() for some heuristics.

We used to maintain a fil_system.LRU list and a counter fil_node_t::n_pending to achieve this, at the huge cost of multiple fil_system.mutex operations per I/O operation. fil_node_open_file_low(): Implement a FIFO replacement policy: The last opened file will be moved to the end of fil_system.space_list, and files will be closed from the start of the list. However, we will not move tablespaces in fil_system.space_list while i_s_tablespaces_encryption_fill_table() is executing (producing output for INFORMATION_SCHEMA.INNODB_TABLESPACES_ENCRYPTION) because it may cause information of some tablespaces to go missing. We also avoid this in mariabackup --backup because datafiles_iter_next() assumes that the ordering is not changed. IORequest: Fold more parameters to IORequest::type. fil_space_t::io(): Replaces fil_io(). fil_space_t::flush(): Replaces fil_flush(). OS_AIO_IBUF: Remove. We will always issue synchronous reads of the change buffer pages in buf_read_page_low(). We will always ignore some errors for background reads. This should reduce fil_system.mutex contention a little. fil_node_t::complete_write(): Replaces fil_node_t::complete_io(). On both read and write completion, fil_space_t::release_for_io() will have to be called. fil_space_t::io(): Do not acquire fil_system.mutex in the normal code path. xb_delta_open_matching_space(): Do not try to open the system tablespace which was already opened. This fixes a file sharing violation in mariabackup --prepare --incremental.

So, let us submit asynchronous writes for the doublewrite buffer. We submit a single request for the likely case that the two doublewrite buffers are contiquous in the system tablespace. buf_dblwr_t::flush_buffered_writes_completed(): The completion callback of buf_dblwr_t::flush_buffered_writes(). os_aio_wait_until_no_pending_writes(): Also wait for doublewrite batches. buf_dblwr_t::element::space: Remove.

As we are in a crashed state, we must prevent allocating any memory (if possible). Thus, switch select call to poll. Also move some bigger datastructures to global space. The code is not run in a multithreaded context so best we don't use up stack space if it's not needed. --- mysys/my_addr_resolve.c | 27 ++++++++++++++++++--------- 1 file changed, 18 insertions(+), 9 deletions(-) diff --git a/mysys/my_addr_resolve.c b/mysys/my_addr_resolve.c index ecb512572b1..e0ebbe699be 100644 --- a/mysys/my_addr_resolve.c +++ b/mysys/my_addr_resolve.c @@ -147,10 +147,18 @@ err: #include +#if defined(HAVE_POLL_H) +#include +#elif defined(HAVE_SYS_POLL_H) +#include +#endif /* defined(HAVE_POLL_H) */ + static int in[2], out[2]; static pid_t pid; static char addr2line_binary[1024]; static char output[1024]; +static struct pollfd poll_fds; +Dl_info info; int start_addr2line_fork(const char *binary_path) { @@ -200,15 +208,16 @@ int my_addr_resolve(void *ptr, my_addr_loc *loc) ssize_t extra_bytes_read = 0; ssize_t parsed = 0; - fd_set set; - struct timeval timeout; + int ret; int filename_start = -1; int line_number_start = -1; - Dl_info info; void *offset; + poll_fds.fd = out[0]; + poll_fds.events = POLLIN | POLLRDBAND; + if (!dladdr(ptr, &info)) return 1; @@ -230,16 +239,16 @@ int my_addr_resolve(void *ptr, my_addr_loc *loc) if (write(in[1], input, len) <= 0) return 1; - FD_ZERO(&set); - FD_SET(out[0], &set); - /* 100 ms should be plenty of time for addr2line to issue a response. */ - timeout.tv_sec = 0; - timeout.tv_usec = 100000; + /* 500 ms should be plenty of time for addr2line to issue a response. */ /* Read in a loop till all the output from addr2line is complete. */ while (parsed == total_bytes_read && - select(out[0] + 1, &set, NULL, NULL, &timeout) > 0) + (ret= poll(&poll_fds, 1, 500))) { + /* error during poll */ + if (ret < 0) + return 1; + extra_bytes_read= read(out[0], output + total_bytes_read, sizeof(output) - total_bytes_read); if (extra_bytes_read < 0) From 00ddea4f2f7d20e09a28655b2f30a4c014e9344a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marko=20M=C3=A4kel=C3=A4?= Date: Tue, 27 Oct 2020 09:52:42 +0200 Subject: [PATCH 247/323] MDEV-24024 innodb.ibuf_not_empty failed in buildbot Probably due to the changes to page flushing in MDEV-23399 (commit 7cffb5f6e8a231a041152447be8980ce35d2c9b8) the command CHECK TABLE would occasionally report a different number of rows for the corrupted secondary index.

This creates an issue with multi statement transactions especially when a statement in the transaction has to access the memory used by the previous statement in the transaction. FIX: ==== Transaction mem_root is freed whenever a transaction is committed or rolled-back. Hence explicitly freeing it is not necessary in the bootstrap implementation.

CREATE TABLE t1 (a INT); UPDATE t1 FOR PORTION OF APPTIME FROM (SELECT 1 FROM t1) TO 2 SET a = 1; Stack trace to the fired assert statement DBUG_ASSERT(thd->lex->sql_command == SQLCOM_UPDATE) listed below: mysql_execute_command() -> mysql_multi_update_prepare() --> Multiupdate_prelocking_strategy::handle_end() --> check_fiels() It's worth to note that this stack trace looks like a multi update statement is being executed. The fired assert is checked inside the function check_fields() in case table->has_period() returns the value true that in turns happens when temporal period specified in the UPDATE statement. Condition specified in the DEBUG_ASSERT statement returns the false value since the data member thd->lex->sql_command have the value SQLCOM_UPDATE_MULTI. So, the main question is why a program control flow go to the path prescribed for handling MULTI update statement despite of the fact that the ordinary UPDATE statement being executed. The answer is a way that SQL grammar rules written. When the statement UPDATE t1 FOR PORTION OF APPTIME FROM (SELECT 1 FROM t1) TO 2 SET a = 1; being parsed an action for the rule 'table_primary_ident' (part of this action is listed below to simplify description) is invoked to handle the table name 't1' specified in the clause 'SELECT 1 FROM t1'. table_primary_ident: table_ident opt_use_partition opt_for_system_time_clause opt_table_alias_clause opt_key_definition { SELECT_LEX *sel= Select; sel->table_join_options= 0; if (!($$= Select->add_table_to_list(thd, $1, $4, This action calls the method st_select_lex::add_table_to_list() to add the table name 't1' to the list of tables being used by the statement. Later, an action for the following grammar rule update_table_list: table_ident opt_use_partition for_portion_of_time_clause opt_table_alias_clause opt_key_definition { SELECT_LEX *sel= Select; sel->table_join_options= 0; if (!($$= Select->add_table_to_list(thd, $1, $4, is invoked to handle the clause 't1 FOR PORTION OF APPTIME FROM ... TO 2'. This action also calls the method st_select_lex::add_table_to_list() to add the table name 't1' to the list of tables being used by the statement. In result the table name 't1' contained twice in this list. Presence of duplicate names for the table 't1' in a list of table used by a statement leads to the fact that the function unique_table() called from the function mysql_update() returns the value true that forces implementation of the function mysql_update() to return the value 2 as a signal to fall through the case boundary of the switch statement placed in the function mysql_execute_statement() and start handling of the case for sql_command SQLCOM_UPDATE_MULTI. The compound statement block for the case SQLCOM_UPDATE_MULTI invokes the function mysql_multi_update_prepare() that executes the statement set thd->lex->sql_command= SQLCOM_UPDATE_MULTI; and after that calls the method Multiupdate_prelocking_strategy::handle_end(). Finally, this method invokes the check_field() function and assert is fired. The above analysis shows that update for a table that simultaneously specified both as a destination table of UPDATE statement and as a table taking part in subquery is actually treated by MariaDB server as multi-update statement. Taking into account that multi-update statement for temporal period table is not supported yet by MariaDB, correct way to fix the bug is to return the error ER_NOT_SUPPORTED_YET for this case. --- mysql-test/suite/period/r/update.result | 12 ++++++++++++ mysql-test/suite/period/t/update.test | 18 ++++++++++++++++++ sql/sql_parse.cc | 5 +++++ sql/sql_update.cc | 8 ++++++++ 4 files changed, 43 insertions(+) diff --git a/mysql-test/suite/period/r/update.result b/mysql-test/suite/period/r/update.result index b02c075560e..b61d8a73b83 100644 --- a/mysql-test/suite/period/r/update.result +++ b/mysql-test/suite/period/r/update.result @@ -292,3 +292,15 @@ Warning 1264 Out of range value for column 'id' at row 1 Warning 1264 Out of range value for column 'id' at row 2 update ignore t1 for portion of p from '1995-07-06' to '2009-01-12' set f = 1; drop table t1; +# +# MDEV-22805 SIGSEGV in check_fields on UPDATE (optimized builds) | Assertion `thd->lex->sql_command == SQLCOM_UPDATE' failed. +# +CREATE TABLE t1 (a INT, b DATE, c DATE, PERIOD FOR APPTIME(b, c)); +INSERT INTO t1 VALUES(1, '1999-01-01', '2018-12-12'); +UPDATE t1 FOR PORTION OF APPTIME FROM (SELECT '1999-01-01' FROM t1 WHERE a=2) TO '2018-01-01' SET a = 100; +ERROR 42000: This version of MariaDB doesn't yet support 'updating and querying the same temporal periods table' +CREATE VIEW v1 AS SELECT * FROM t1; +UPDATE v1 FOR PORTION OF APPTIME FROM (SELECT '1999-01-01' FROM t1 WHERE a=2) TO '2018-01-01' SET a = 100; +ERROR 42S02: 'v1' is a view +DROP VIEW v1; +DROP TABLE t1; diff --git a/mysql-test/suite/period/t/update.test b/mysql-test/suite/period/t/update.test index d4a2080ea0a..66d3bc1e9bf 100644 --- a/mysql-test/suite/period/t/update.test +++ b/mysql-test/suite/period/t/update.test @@ -183,3 +183,21 @@ update ignore t1 set id = 2429681664; update ignore t1 for portion of p from '1995-07-06' to '2009-01-12' set f = 1; drop table t1; + +--echo # +--echo # MDEV-22805 SIGSEGV in check_fields on UPDATE (optimized builds) | Assertion `thd->lex->sql_command == SQLCOM_UPDATE' failed. +--echo # +CREATE TABLE t1 (a INT, b DATE, c DATE, PERIOD FOR APPTIME(b, c)); + +INSERT INTO t1 VALUES(1, '1999-01-01', '2018-12-12'); + +# Without a patch the following statement crashs a server built in debug mode +--error ER_NOT_SUPPORTED_YET +UPDATE t1 FOR PORTION OF APPTIME FROM (SELECT '1999-01-01' FROM t1 WHERE a=2) TO '2018-01-01' SET a = 100; + +CREATE VIEW v1 AS SELECT * FROM t1; +--error ER_IT_IS_A_VIEW +UPDATE v1 FOR PORTION OF APPTIME FROM (SELECT '1999-01-01' FROM t1 WHERE a=2) TO '2018-01-01' SET a = 100; + +DROP VIEW v1; +DROP TABLE t1; diff --git a/sql/sql_parse.cc b/sql/sql_parse.cc index 7504863f394..e8c94c6b363 100644 --- a/sql/sql_parse.cc +++ b/sql/sql_parse.cc @@ -4373,6 +4373,11 @@ mysql_execute_command(THD *thd) /* mysql_update return 2 if we need to switch to multi-update */ if (up_result != 2) break; + if (thd->lex->period_conditions.is_set()) + { + DBUG_ASSERT(0); // Should never happen + goto error; + } } /* fall through */ case SQLCOM_UPDATE_MULTI: diff --git a/sql/sql_update.cc b/sql/sql_update.cc index 31a015dd0e2..c687b6ca2f5 100644 --- a/sql/sql_update.cc +++ b/sql/sql_update.cc @@ -420,6 +420,14 @@ int mysql_update(THD *thd, DBUG_PRINT("info", ("Switch to multi-update")); /* pass counter value */ thd->lex->table_count= table_count; + if (thd->lex->period_conditions.is_set()) + { + my_error(ER_NOT_SUPPORTED_YET, MYF(0), + "updating and querying the same temporal periods table"); + + DBUG_RETURN(1); + } + /* convert to multiupdate */ DBUG_RETURN(2); } From bc540b8706a404c8aec81a599c7e7ec1a46b5ad1 Mon Sep 17 00:00:00 2001 From: Thirunarayanan Balathandayuthapani Date: Tue, 27 Oct 2020 17:56:49 +0530 Subject: [PATCH 255/323] MDEV-23693 Failing assertion: my_atomic_load32_explicit(&lock->lock_word, MY_MEMORY_ORDER_RELAXED) == X_LOCK_DECR InnoDB frees the block lock during buffer pool shrinking when other thread is yet to release the block lock. While shrinking the buffer pool, InnoDB allows the page to be freed unless it is buffer fixed. In some cases, InnoDB releases the latch after unfixing the block. Fix: ==== - InnoDB should unfix the block after releases the latch. - Add more assertion to check buffer fix while accessing the page. - Introduced block_hint structure to store buf_block_t pointer and allow accessing the buf_block_t pointer only by passing a functor. It returns original buf_block_t* pointer if it is valid or nullptr if the pointer become stale. - Replace buf_block_is_uncompressed() with buf_pool_t::is_block_pointer() This change is motivated by a change in mysql-5.7.32: mysql/mysql-server@46e60de444a8fbd876cc6778a7e64a1d3426a48d Bug #31036301 ASSERTION FAILURE: SYNC0RW.IC:429:LOCK->LOCK_WORD --- storage/innobase/CMakeLists.txt | 1 + storage/innobase/btr/btr0bulk.cc | 4 ++ storage/innobase/btr/btr0cur.cc | 43 +++++-------- storage/innobase/btr/btr0pcur.cc | 39 ++++++++---- storage/innobase/buf/buf0block_hint.cc | 78 +++++++++++++++++++++++ storage/innobase/buf/buf0buf.cc | 76 +--------------------- storage/innobase/gis/gis0sea.cc | 25 ++++++-- storage/innobase/include/btr0pcur.h | 11 ++-- storage/innobase/include/buf0block_hint.h | 77 ++++++++++++++++++++++ storage/innobase/include/buf0buf.h | 17 ++--- storage/innobase/include/buf0buf.ic | 35 ++++++---- storage/innobase/include/mtr0mtr.ic | 4 +- storage/innobase/include/trx0undo.h | 2 - storage/innobase/mtr/mtr0mtr.cc | 4 +- storage/innobase/trx/trx0rec.cc | 10 +-- storage/innobase/trx/trx0undo.cc | 1 - 16 files changed, 262 insertions(+), 165 deletions(-) create mode 100644 storage/innobase/buf/buf0block_hint.cc create mode 100644 storage/innobase/include/buf0block_hint.h diff --git a/storage/innobase/CMakeLists.txt b/storage/innobase/CMakeLists.txt index 1b5345cbddc..08e8e3ff5ab 100644 --- a/storage/innobase/CMakeLists.txt +++ b/storage/innobase/CMakeLists.txt @@ -28,6 +28,7 @@ SET(INNOBASE_SOURCES btr/btr0scrub.cc btr/btr0sea.cc btr/btr0defragment.cc + buf/buf0block_hint.cc buf/buf0buddy.cc buf/buf0buf.cc buf/buf0dblwr.cc diff --git a/storage/innobase/btr/btr0bulk.cc b/storage/innobase/btr/btr0bulk.cc index 96ff81c9fab..100e48cf537 100644 --- a/storage/innobase/btr/btr0bulk.cc +++ b/storage/innobase/btr/btr0bulk.cc @@ -695,6 +695,8 @@ PageBulk::latch() m_mtr.set_named_space(m_index->space); } + ut_ad(m_block->page.buf_fix_count); + /* In case the block is S-latched by page_cleaner. */ if (!buf_page_optimistic_get(RW_X_LATCH, m_block, m_modify_clock, __FILE__, __LINE__, &m_mtr)) { @@ -713,6 +715,8 @@ PageBulk::latch() buf_block_buf_fix_dec(m_block); + ut_ad(m_block->page.buf_fix_count); + ut_ad(m_cur_rec > m_page && m_cur_rec < m_heap_top); return (m_err); diff --git a/storage/innobase/btr/btr0cur.cc b/storage/innobase/btr/btr0cur.cc index 770c6d73585..6ae6bad10c8 100644 --- a/storage/innobase/btr/btr0cur.cc +++ b/storage/innobase/btr/btr0cur.cc @@ -416,6 +416,8 @@ btr_cur_optimistic_latch_leaves( ulint mode; ulint left_page_no; ulint curr_page_no; + ut_ad(block->page.buf_fix_count); + ut_ad(buf_block_get_state(block) == BUF_BLOCK_FILE_PAGE); switch (*latch_mode) { case BTR_SEARCH_LEAF: @@ -427,20 +429,10 @@ btr_cur_optimistic_latch_leaves( mode = *latch_mode == BTR_SEARCH_PREV ?

There is a type number clash between MySQL and MariaDB. The number 245, used for MariaDB Virtual Fields is the same as MySQL's JSON. This leads to corrupt FRM errors if unhandled. The code properly checks frm table version number and if it matches 5.7+ (until 10.0+) it will assume it is dealing with a MySQL table with the JSON datatype. 2. MySQL JSON datatype uses a proprietary format to pack JSON data. The patch introduces a datatype plugin which parses the format and convers it to its string representation. The intended conversion path is to only use the JSON datatype within ALTER TABLE FORCE, to force a table recreate. This happens during mysql_upgrade or via a direct ALTER TABLE

In case this number is not equal to actual query parameters number, the server may start to interprete packet data incorrectly, e.g. starting from the size of null bitmap. And that could cause it to crash at some point. The commit introduces some additional COM_STMT_EXECUTE packet sanity checks: - checking that "types sent" byte is set, and the value is equal to 1. if it's not direct execution, then that value is 0 or 1. - checking that parameter type value is a valid type, and parameter flags value is 0 or only "unsigned" bit is set - added more checks that read does not go beyond the end of the packet --- sql/sql_prepare.cc | 199 +++++++++++++++++++++++++++++++++++--- tests/mysql_client_test.c | 149 ++++++++++++++++++++++++++++ 2 files changed, 336 insertions(+), 12 deletions(-) diff --git a/sql/sql_prepare.cc b/sql/sql_prepare.cc index 1efb9d713bc..0df2617bb9a 100644 --- a/sql/sql_prepare.cc +++ b/sql/sql_prepare.cc @@ -123,6 +123,9 @@ When one supplies long data for a placeholder: #include "transaction.h" // trans_rollback_implicit #include "wsrep_mysqld.h" +/* Constants defining bits in parameter type flags.

If the table was already in clean state, it is possible that the data file is not open. fil_space_t::flush_low(): If the data file is not open, check with a debug assertion that there are no unflushed changes, and carry on.

This was leading to a buffer overflow as the values were written to the buffer without truncation and then we moved the offset to the number of bytes(set by max_sort_length), that are needed for comparison.

Subtracting table->record[0] from record is UB (non-contiguous buffers) 2. It is very popular to use move_field_offset, which changes Field::ptr, but leaves table->record[0] unchanged. This makes a ptr_in_record result incorrect, since it relies on table->record[0] value.

Even though the handlers are different, they share a common table, so the value is anyway spoiled. This is bad, and table->status is badly designed and overweighted by functionality, but nothing can be done with it, since the code related to this logic is ancient and it's impossible to extract it with normal effort. So let's just save and restore the value in ha_update_row before and after the checks. Other operations like INSERT and simple UPDATE are not in risk, since they don't use this table->status approach. DELETE does not do any unique checks, so it's also safe. --- mysql-test/suite/period/r/overlaps.result | 9 +++++++++ mysql-test/suite/period/t/overlaps.test | 14 ++++++++++++++ sql/handler.cc | 15 +++++++++------ 3 files changed, 32 insertions(+), 6 deletions(-) diff --git a/mysql-test/suite/period/r/overlaps.result b/mysql-test/suite/period/r/overlaps.result index fcd54a0a942..f5839a84e4b 100644 --- a/mysql-test/suite/period/r/overlaps.result +++ b/mysql-test/suite/period/r/overlaps.result @@ -320,4 +320,13 @@ t1 CREATE TABLE `t1` ( PARTITION `pn` CURRENT ENGINE = InnoDB) insert into t1 values (1,'2013-01-12','2015-11-04'), (2,'2016-03-15','2024-11-09');

The problem is described as follows: 1. `append_system_key_parts` was called before `mysql_prepare_create_table`, though key name generation was done close to the latest stage of the latter. 2. We can't move `append_system_key_parts` in the end, because system keys should be appended before some checks done. 3. If the checks from `append_system_key_parts` are moved to the end of `mysql_prepare_create_table`, then some other inappropriate errors are issued. like `ER_DUP_FIELDNAME`. To have key name specified in error message, name generation should be done before the checks, which consequenced in more changes. The final design for key initialization in `mysql_prepare_create_table` follows. The initialization is done in three phases: 1. Calculate a total number of keys created with respect to keys ignored. Allocate KEY* buffer. 2. Generate unique names; calculate a total number of key parts. Make early checks. Allocate KEY_PART_INFO* buffer. 3. Initialize key parts, make the rest of the checks. --- mysql-test/suite/period/r/overlaps.result | 2 +- sql/sql_table.cc | 200 ++++++++++++---------- 2 files changed, 110 insertions(+), 92 deletions(-) diff --git a/mysql-test/suite/period/r/overlaps.result b/mysql-test/suite/period/r/overlaps.result index efbbe7cf15b..b8f23ce413c 100644 --- a/mysql-test/suite/period/r/overlaps.result +++ b/mysql-test/suite/period/r/overlaps.result @@ -127,7 +127,7 @@ ERROR HY000: Period `p` is not found in table create or replace table t(id int, s date, e date, period for p(s,e), primary key(id, s, p without overlaps));
