Igor Babaev	ca2cdaad86	The patch for the task mdev-539. The patch lifts the limitation of the current implementation of ALTER TABLE that does not allow to build unique/primary indexes by sort for MyISAM and Aria engines.	13 years ago
Sergey Petrunya	28c9e1a550	Cassandra Storage Engine: Address review feedback part #3 - Cleanup ha_cassandra::store_lock() - Remove dummy ha_cassandra::delete_table() - Add HA_TABLE_SCAN_ON_INDEX to table_flags()	13 years ago
Sergey Petrunya	6b47b2fe98	Cassandra Storage Engine: Address review feedback part # 2 - Register counters directly in the array passed to maria_declare_plugin. As a consequence, FLUSH TABLES will reset the counters. - Update test results accordingly.	13 years ago
Sergey Petrunya	7e5ef40779	Cassandra Storage Engine: - Partially address review feedback. - Update cassandra.test result result - make cassandra.test timezone-agnostic	13 years ago
Igor Babaev	f6636852c4	Merge mwl248->10.0-base.	13 years ago
unknown	e99aa91e90	MDEV-3928: Assertion `example' failed in Item_cache::is_expensive_processor with a 2-level IN subquery Analysis: The following call stack shows that it is possible to set Item_cache::value_cached, and the relevant value without setting Item_cache::example. #0 Item_cache_temporal::store_packed at item.cc:8395 #1 get_datetime_value at item_cmpfunc.cc:915 #2 resolve_const_item at item.cc:7987 #3 propagate_cond_constants at sql_select.cc:12264 #4 propagate_cond_constants at sql_select.cc:12227 #5 optimize_cond at sql_select.cc:13026 #6 JOIN::optimize at sql_select.cc:1016 #7 st_select_lex::optimize_unflattened_subqueries at sql_lex.cc:3161 #8 JOIN::optimize_unflattened_subqueries at opt_subselect.cc:4880 #9 JOIN::optimize at sql_select.cc:1554 The fix is to set Item_cache_temporal::example even when the value is set directly by Item_cache_temporal::store_packed. This makes the Item_cache_temporal object consistent.	13 years ago
unknown	490d2a4267	Previous change of have_debug_sync.inc broke non-debug builds. Implement it in a different way that works on both release and debug builds, and still uses --skip instead of --require.	13 years ago
Sergei Golubchik	6a742fc3b1	MDEV-3927 Add variable "have yassl" have_openssl variable was ON even when OpenSSL was not used (but YaSSL was). fix that, so that have_openssl really corresponds to OpenSSL rename not_openssl.inc to not_ssl.inc and fix the test accordingly.	13 years ago
Sergei Golubchik	6c3de76ad5	fix have_debug_sync.inc remove unused require files	13 years ago
Sergei Golubchik	1d2b11b291	MDEV-438 Microseconds: Precision is ignored in CURRENT_TIMESTAMP(N) when it is given as a default column value For MySQL 5.6 compatibility, support precision specification in CURRENT_TIMESTAMP in a default clause, when it's not less than the column's precision.	13 years ago
Sergei Golubchik	cb7f5948ec	simplify the handler api - table_type() is no longer abstract, not even virtual	13 years ago
Sergei Golubchik	a058974440	remove HAVE_EXPLICIT_TEMPLATE_INSTANTIATION	13 years ago
unknown	cd0970c480	MDEV-532: Fix some race conditions in test cases. With MDEV-532, the binlog_checkpoint event is logged asynchronously from a binlog background thread. This causes some sporadic failures in some test cases whose output depends on order of events in binlog. Fix using an include file that waits until the binlog checkpoint event has been logged before proceeding with the test case.	13 years ago

unknown	40bbf697aa	MDEV-532: Async InnoDB commit checkpoint. Make the commit checkpoint inside InnoDB be asynchroneous. Implement a background thread in binlog to do the writing and flushing of binlog checkpoint events to disk.	13 years ago
unknown	e97d6232f3	Automatic merge MDEV-452 with the latest 10.0-base.	13 years ago
Igor Babaev	a06224bd15	Addressed all remaining issues from the review of the patch that introduced engine independent persistent statistics. In particular: - added an enumeration type for possible values of the system variable use_stat_tables - renamed KEY::real_rec_per_key to KEY::actual_rec_per_key - optimized the collection of statistical data for any primary key defined only on one column.	13 years ago
unknown	6e8c4d696a	MDEV-452 Add full support for auto-initialized/updated timestamp and datetime Post-review changes according to Monty's review from 28/11/2012.	13 years ago
Igor Babaev	65820439bd	Fixed bug mdev-3891. If a query referenced some system statistical tables, but not all of them, then executing an ANALYZE command simultaneously with this query could lead to a deadlock. The fix prohibited reading statistics from system statistical tables for such queries. Removed the function unlock_tables_n_open_system_tables_for_write() as not used anymore. Performed some minor refactoring of the code in sql_statistics.cc.	13 years ago
Sergei Golubchik	532d9c3028	one-byte overflow with old passwords	13 years ago
Dmitry Lenev	14ba37f76f	Bug #15954896 "SP, MULTI-TABLE DELETE AND LONG ALIAS". Using too long table aliases in stored routines might have caused server crashes. Code in sp_head::merge_table_list() which is responsible for collecting information about tables used in stored routine was not aware of the fact that table alias might have arbitrary length. I.e. it assumed that table alias can't be longer than NAME_LEN bytes and allocated buffer for a key identifying table accordingly. This patch fixes the issue by ensuring that we use dynamically allocated buffer for table key when table alias is too long. By default stack based buffer is used in which NAME_LEN bytes are reserved for table alias.	13 years ago
Igor Babaev	109c104d07	Addressed the following issue from the review of the patch for engine-independent statistics. If a table was created for InnoDB then the execution of the ANALYZE command over this table blocked any INSERT/DELETE/UPDATE of the table.	13 years ago
Igor Babaev	2447bc4c81	Addressed the following issue from the review of the patch for engine-independent statistics. When the primary key was dropped or changed statistics on secondary indexes for the prefixes that included components of the primary key was not removed from the table mysql.index_stats. Also fixed: in the some cases when a column was changed statistics on the indexes that included this column was not removed from the table mysql.index_stats. Also disabled the test mdev-504 for --ps-protocol.	13 years ago

Joerg Bruehe	d07b5f1ca2	Last-minute fix to 5.1.67, taking a change done to main 5.1 by Dmitri Lenev.

Sergei Golubchik	63e92a2b6c	if the debian package name for 5.5.28 is 5.5.28-mariadb1~wheezy then for 5.5.28a it should be 5.5.28a-mariadb1~wheezy not 5.5.28-mariadb-a1~wheezy	13 years ago
unknown	a8bad7d900	MDEV-3902 Assertion `record_length == m_record_length' failed at Filesort_buffer::alloc_sort_buffer This bug is a duplicate of mdev-3899 so adding a test case only.	13 years ago
Vladislav Vaintroub	21b4fda3a5	MDEV-3945 - do not hold LOCK_thread_count when freeing THD. The patch decreases the duration of LOCK_thread_count, so it is not hold during THD destructor and freeing memory. This mutex now only protects the integrity of threads list, when removing THD from it, and thread_count variable. The add_to_status() function that updates global status during client disconnect, is now correctly protected by the LOCK_status mutex. Benchmark : in a "non-persistent" sysbench test (oltp_ro with reconnect after each query), ~ 25% more connects/disconnects were measured	13 years ago
unknown	1b2692d0e9	MDEV-3899 Valgrind warnings (blocks are definitely lost) in filesort on IN subquery with SUM and DISTINCT Analysys: In the beginning of JOIN::cleanup there is code that is supposed to free all filesort buffers. The code assumes that the table being sorted is the first non-constant table. To get this table it calls: first_top_level_tab(this, WITHOUT_CONST_TABLES) However, first_top_level_tab() instead returned the wrong table - the first one in the plan, instead of the first non-constant table. There is no other place outside filesort() where sort buffers may be freed. As a result, the sort buffer was not freed, and there was a memory leak. Solution: Change first_top_level_tab(), to test for WITH_CONST_TABLES instead of WITHOUT_CONST_TABLES.	13 years ago
Michael Widenius	35b6020835	Fixed some compiler warnings client/mysqldump.c: Removed compiler warning extra/yassl/taocrypt/include/pwdbased.hpp: Removed compiler warning (iterations is always unsigned) support-files/compiler_warnings.supp: Ignore warnings from groff	13 years ago
unknown	fef08da3e7	MDEV-3818: Query against view over IS tables worse than equivalent query without view Fixed the test to be lower-case because it fails on windows with mixed case.	13 years ago
Michael Widenius	2dbce3d089	Fixed the CREATE TABLE IF EXIST generates warnings instead of errors mysql-test/r/create.result: Updated test results mysql-test/t/create.test: Updated test sql/sql_base.cc: Use push_internal_handler/pop_internal_handler to avoid errors & warnings instead of clear_error Give a warnings instead of an error for CREATE TABLE IF EXISTS sql/sql_parse.cc: Check if we failed because of table exists (can only happen from create) sql/sql_table.cc: Check if we failed because of table exists (can only happen from create)	13 years ago
unknown	d7a0148758	MDEV-3818: Query against view over IS tables worse than equivalent query without view Analysis: The reason for the suboptimal plan when querying IS tables through a view was that the view columns that participate in an equality are wrapped by an Item_direct_view_ref and were not recognized as being direct column references. Solution: Use the original Item_field objects via the real_item() method.	13 years ago
Michael Widenius	a334e87d65	Remember original table row pack type for ALTER TABLE if table is not copied.	13 years ago
Michael Widenius	b31909ffbb	Removed lock wait timeout warning when using CREATE TABLE IF EXISTS mysql-test/r/create.result: Added test case to show that CREATE TABLE also is not waiting if table exists. mysql-test/t/create.test: Added test case to show that CREATE TABLE also is not waiting if table exists. sql/sql_base.cc: Clear also warnings from acquire_locks if we retry.	13 years ago
Michael Widenius	33f3a11e2d	Implemented MDEV-3941: CREATE TABLE xxx IF NOT EXISTS should not block if table exists. - Added option to check_if_table_exists() to quickly check if table exists (either SHARE or .FRM) - Extended lock_table_names() to not wait for meta data locks if CREATE IF NOT EXISTS is used. mysql-test/r/create.result: New test case mysql-test/t/create.test: New test case sql/sql_base.cc: Added option to check_if_table_exists() to quickly check if table exists (either SHARE or .FRM) Extended lock_table_names() to not wait for meta data locks if CREATE IF NOT EXISTS is used. sql/sql_base.h: Updated prototype sql/sql_db.cc: Added extra argument to call to check_if_table_exists()	13 years ago

Michael Widenius	4ba960569b	Removed extra '+' from some lines (remains of old merge)	13 years ago
Harin Vadodaria	d8876ff2fb	Bug#15912213: BUFFER OVERFLOW IN ACL_GET() Description: A very large database name causes buffer overflow in functions acl_get() and check_grant_db() in sql_acl.cc. It happens due to an unguarded string copy operation. This puts required sanity checks before copying db string to destination buffer.	13 years ago
Igor Babaev	dd119466c3	Addressed the following issues from the review of the patch: 1. The PERSISTENT FOR clause of the ANALYZE command overrides the setting of the system variable use_stat_tables: with this clause ANALYZE unconditionally collects persistent statistics. 2. ANALYZE collects persistent statistics only for tables of the USER category. So it never collects persistent statistics for system tables.	13 years ago
Vladislav Vaintroub	c4b35f9279	MDEV-3918: myisamchk bogus error for files larger than 4GB. The failure is caused by failing stat() call . C Runtime function stat() uses old struct with 32bit st_size member, and since Visual Studio 2010 , it returns an error on st_size overflow (i.e on files larger than 4GB) Fix replaces stat() by my_stat(), the later is backed by 64bit-able stat64().	13 years ago
unknown	0aad592f49	MDEV-3914 fix. Fixed algorithm of detecting of first real table in view/subquery-in-the-FROM-clase.	13 years ago
Igor Babaev	81563081e5	Adjusted results for a test. The adjustment was supposed to be done in the previous commit.	13 years ago
Gleb Shchepa	e5424d196b	Bug #15948123 : SERVER WORKS INCORRECT WITH LONG TABLE ALIASES After-push cleanup: removal of unneeded assertions.	13 years ago
Gleb Shchepa	d538d394b8	Bug #15948123 : SERVER WORKS INCORRECT WITH LONG TABLE ALIASES Code in MDL subsystem assumes that identifiers of objects can't be longer than NAME_LEN characters. This assumption was broken when one tried to construct MDL_key based on table alias, which can have arbitrary length. Since MDL_key's (and MDL locks) are not really used for table aliases this patch changes code to not initialize MDL_key object for table list element representing aliases.	13 years ago
Igor Babaev	b110132516	Changed the names of the system tables for statistical data: table_stat -> table_stats column_stat -> column_stats index_stat -> index_stats to be in line with the names of innodb statistical tables from mysql-5.6: innodb_table_stats and innodb_index_stats.	13 years ago
Igor Babaev	f8bfb65b13	Merge 5.5->mwl248	13 years ago
