Oleksandr Byelkin	9c9cf556a1	MDEV-13933: Wrong results in COUNT() query with EXISTS and exists_to_in Roll back to most general duplicate removing strategi in case of different stratagies for one position.	8 years ago
Marko Mäkelä	a9c55c0059	MDEV-13814 Extra logging when innodb_log_archive=ON Backport the fix from 10.0.33 to 5.5, in case someone compiles XtraDB with -DUNIV_LOG_ARCHIVE	8 years ago
Marko Mäkelä	a408e881cf	MDEV-14174 crash on start with innodb-track-changed-pages The XtraDB option innodb_track_changed_pages causes the function log_group_read_log_seg() to be invoked even when recv_sys==NULL, leading to the SIGSEGV. This regression was caused by MDEV-11027 InnoDB log recovery is too noisy	8 years ago
Marko Mäkelä	84c9c8b2e9	Silence some -Wimplicit-fallthrough by proper spelling	8 years ago
Marko Mäkelä	20fab71b14	Follow-up to MDEV-14799: Remove bogus debug assertions trx_undo_rec_get_partial_row(): When the PRIMARY KEY includes a column prefix of an externally stored column, the already parsed part of the undo log record may contain a reference to an off-page column. This is the case in the bug58912 test in innodb.innodb.	8 years ago
Marko Mäkelä	d384ead0f0	MDEV-14799 After UPDATE of indexed columns, old values will not be purged from secondary indexes This is a regression caused by MDEV-14051 'Undo log record is too big.' Purge in the secondary index is wrongly skipped in row_purge_upd_exist_or_extern() because node->row only does not contain all indexed columns. trx_undo_rec_get_partial_row(): Add the parameter for node->update so that the updated columns will be copied from the initial part of the undo log record.	8 years ago
Sergei Golubchik	1300627a5d	MDEV-14309 MTR tests require perl-Env which is not always in the default installation * don't use Env module in tests, use $ENV{xxx} instead * collateral changes: $file in the error message was unset $file in the other error message was unset too :) source file arguments are conventionally upper-cased abort the test (die) on error, don't just echo/exit	8 years ago
Oleksandr Byelkin	462808f3b6	MDEV-10657: incorrect result returned with binary protocol (prepared statements) If translation table present when we materialize the derived table then change it to point to the materialized table. Added debug info to see really what happens with what derived.	8 years ago
Varun Gupta	924db8b4ed	MDEV-12350: Heap corruption, overrun buffer, ASAN errors, server crash in my_fill_8bit / filesort In the function make_sortkey a tmp buffer was defined and in the absence of param->tmp_buffer, tmp buffer used the sort_keys buffer. sort_keys buffer has a length defined in sort_field->length, while param->tmp_buffer is stored in param->rec_length. Make sure to use the appropriate length based on which buffer we are using otherwise we'll overflow. Also added a type cast to size_t during the calculation of the sort keys buffer size to avoid an oveflow if the buffer size exceeds 32 bits.	8 years ago

Vicențiu Ciorbaru	ac61a575df	Revert "Remove use of volatile in stored_field_cmp_to_item" This reverts commit `7603463a46`. The commit itself is fine, however when disabling volatile, compiler optimizations mess up our double results due to precision differences. Revert the patch till a proper solution is found.	8 years ago
Daniel Black	7603463a46	Remove use of volatile in stored_field_cmp_to_item This was added in `c796415943` but would hurt all other compilers because of Visual Studio. Hopefully this has been fixed now. Signed-off-by: Daniel Black <daniel@linux.vnet.ibm.com>	8 years ago

Jan Lindström	f7b110bdc1	MDEV-9663: InnoDB assertion failure: cursor->index->name == TEMP_INDEX_PREFIX Imported missing test case from MySQL 5.7 for commit `25781c1543` Author: Annamalai Gurusami <annamalai.gurusami@oracle.com> Date: Mon Feb 24 14:00:03 2014 +0530 Bug #17604730 ASSERTION: CURSOR->INDEX->NAME == TEMP_INDEX_PREFIX MariaDB 5.5 does not seem to be affected.	8 years ago
Igor Babaev	b5cb4ae470	Fixed bug MDEV-14368 Improper error for a grouping query that uses alias in HAVING when sql_mode = 'ONLY_FULL_GROUP_BY' This patch corrects the patch for bug#18739: non-standard HAVING extension was allowed in strict ANSI sql mode added in 2006 by commit `4b7c4cd27f`. As a result of incompleteness of the fix in the above commit if a query with GROUP BY contained an aggregate function with an alias and this alias was used in the HAVING clause of the query the server reported an error when sql_mode was set to 'ONLY_FULL_GROUP_BY'.	8 years ago

Marko Mäkelä	cfb3361748	MDEV-12569 InnoDB suggests filing bugs at MySQL bug tracker Replace all references in InnoDB and XtraDB error log messages to bugs.mysql.com with references to https://jira.mariadb.org/.	8 years ago
Marko Mäkelä	439a7c994a	MDEV-14051 'Undo log record is too big.' error occurring in very narrow range of string lengths InnoDB was writing unnecessary information to the update undo log records. Most notably, if an indexed column is updated, the old value of the column would be logged twice: first as part of the update vector, and then another time because it is an indexed column. Because the InnoDB undo log record must fit in a single page, this would cause unnecessary failure of certain updates. Even after this fix, InnoDB still seems to be unnecessarily logging indexed column values for non-updated columns. It seems that non-updated secondary index columns only need to be logged when a PRIMARY KEY column is updated. To reduce risk, we are not fixing this remaining flaw in GA versions. trx_undo_page_report_modify(): Log updated indexed columns only once.	8 years ago

Sergei Golubchik	b000e16956	Bug#26361149 MYSQL SERVER CRASHES AT: COL IN(IFNULL(CONST, COL), NAME_CONST('NAME', NULL)) based on: commit `f7316aa0c9` Author: Ajo Robert <ajo.robert@oracle.com> Date: Thu Aug 24 17:03:21 2017 +0530 Bug#26361149 MYSQL SERVER CRASHES AT: COL IN(IFNULL(CONST, COL), NAME_CONST('NAME', NULL)) Backport of Bug#19143243 fix. NAME_CONST item can return NULL_ITEM type in case of incorrect arguments. NULL_ITEM has special processing in Item_func_in function. In Item_func_in::fix_length_and_dec an array of possible comparators is created. Since NAME_CONST function has NULL_ITEM type, corresponding array element is empty. Then NAME_CONST is wrapped to ITEM_CACHE. ITEM_CACHE can not return proper type(NULL_ITEM) in Item_func_in::val_int(), so the NULL_ITEM is attempted compared with an empty comparator. The fix is to disable the caching of Item_name_const item.	8 years ago

Sergei Golubchik	b036b6b594	MDEV-13937 Aria engine: Internal Error 160 after partition handling Partition wasn't setting HA_OPTION_PACK_RECORD on ALTER TABLE if the row format was PAGE.

Sergei Golubchik	421716391b	MDEV-13912 Can't refer the same column twice in one ALTER TABLE backport `ce6c0e584e` MDEV-8960: Can't refer the same column twice in one ALTER TABLE Problem was that if column was created in alter table when it was refered again it was not tried to find from list of current columns. mysql_prepare_alter_table: There is two cases (1) If alter table adds a new column and then later alter changes the field definition, there was no check from list of new columns, instead an incorrect error was given. (2) If alter table adds a new column and then later alter changes the default, there was no check from list of new columns, instead an incorrect error was given.	8 years ago
Sergei Golubchik	93144b9e92	MDEV-13440 mysql_install_db fails with hard-coded langdir always search in compile-time specified paths INSTALL_BINDIR, INSTALL_SBINDIR, INSTALL_MYSQLSHAREDIR. User can set them to arbitrary values, it's not enough to search only in their usual values of bin, sbin and libexec, share and share/mysql.	8 years ago
Sergei Golubchik	52516706c8	cleanup mysql_install_db 1. detect resolveip location, don' assume it's in $basedir/bin 2. don't guess $scriptdir to (incorrectly) construct the $0 path 3. rename find_in_basedir -> find_in_dirs, don't prepend $basedir automatically. This allows to use identical path lists in find_in_dirs and in cannot_find_file. 4. move search path lists to CMakeLists.txt to avoid specifying the same path list twice (in find_in_dirs and in cannot_find_file).	8 years ago

Igor Babaev	2bab29ebba	Fixed the bug mdev-13135. For each SELECT the list sj_nests is built by the function simplify_joins() when scanning different join nests. This function may be called several times for the same join nest. That's why before adding a new member to sj_nests it is necessary to check if it's already in the list. The code of simplify_joins() lacked this check and as a result it could cause memory overwright for some queries.	8 years ago
Sergey Vojtovich	8be76a6a90	MDEV-10892 - rpl.rpl_semi_sync_uninstall_plugin fails with Assertion `0' failure in buildbot Removed plugin_array_version: it is being checked without mutex protection and thus is prone to data race and race conditions. In effect plugins are not protected from concurrent destruction. Removed state_mask inversion: doesn't seem to make any sense. When collecting local plugins list, only add plugins that match state_mask. Use plugin ref counting to protect against concurrent plugin destruction.	8 years ago

Anushree Prakash B	5ac61b2af0	Bug#26372491 - RCE THROUGH THE MISHANDLE OF BACKSLASH DESCRIPTION: =========== The bug is related to incorrect parsing of SQL queries when typed in on the CLI. The incorrect parsing can result in unexpected results. ANALYSIS: ======== The scenarios mainly happens for identifier names with a typical combination of backslashes and backticks. The incorrect parsing can either result in executing additional queries or can result in query truncation. This can impact mysqldump as well. FIX: === The fix makes sure that such identifier names are correctly parsed and a proper query is sent to the server for execution. (cherry picked from commit `31a372aa1c`)	8 years ago
