Sergey Vojtovich	db5bb785f9	Allocate trx_sys.mvcc at link time trx_sys.mvcc was allocated dynamically for no good reason.	8 years ago
Marko Mäkelä	f8882cce93	Replace trx_sys_t* trx_sys with trx_sys_t trx_sys There is only one transaction system object in InnoDB. Allocate the storage for it at link time, not at runtime. lock_rec_fetch_page(): Use the correct fetch mode BUF_GET. Pages may never be deallocated from a tablespace while record locks are pointing to them.	8 years ago
Sergey Vojtovich	7078203389	MDEV-14756 - Remove trx_sys_t::rw_trx_list Use atomic operations when accessing trx_sys_t::max_trx_id. We can't yet move trx_sys_t::get_new_trx_id() out of mutex because it must be updated atomically along with trx_sys_t::rw_trx_ids.	8 years ago
Sergey Vojtovich	c6d2842d9a	MDEV-14756 - Remove trx_sys_t::rw_trx_list Remove rw_trx_list.	8 years ago
Sergey Vojtovich	a447980ff3	MDEV-14756 - Remove trx_sys_t::rw_trx_list Let lock_print_info_all_transactions() iterate rw_trx_hash instead of rw_trx_list. When printing info of locks for transactions, InnoDB monitor doesn't attempt to read relevant page from disk anymore. The code was prone to race conditions. Note that TrxListIterator didn't work as advertised: it iterated rw_trx_list only.	8 years ago
Sergey Vojtovich	886af392d3	MDEV-14756 - Remove trx_sys_t::rw_trx_list Let trx_rollback_recovered() iterate rw_trx_hash instead of rw_trx_list.	8 years ago
Sergey Vojtovich	02270b44d0	MDEV-14756 - Remove trx_sys_t::rw_trx_list Let lock_validate_table_locks(), lock_rec_other_trx_holds_expl(), lock_table_locks_lookup(), trx_recover_for_mysql(), trx_get_trx_by_xid(), trx_roll_must_shutdown(), fetch_data_into_cache() iterate rw_trx_hash instead of rw_trx_list.	8 years ago
Sergey Vojtovich	d8c0caad32	MDEV-14756 - Remove trx_sys_t::rw_trx_list Removed trx_sys_validate_trx_list(): with rw_trx_hash elements are not required to be ordered by transaction id. Transaction state is now guarded by asserts in rw_trx_hash_t.	8 years ago
Sergey Vojtovich	900b07908b	MDEV-14756 - Remove trx_sys_t::rw_trx_list Removed trx_sys_t::n_prepared_recovered_trx: never used. Removed trx_sys_t::n_prepared_trx: used only at shutdown, we can perfectly get this value from rw_trx_hash.	8 years ago
Sergey Vojtovich	a0b385ea2b	MDEV-14756 - Remove trx_sys_t::rw_trx_list Determine minimum transaction id by iterating rw_trx_hash, not rw_trx_list. It is more expensive than previous implementation since it does linear search, especially if there're many concurrent transactions running. But in such case mutex is much bigger evil. And since it doesn't require trx_sys->mutex protection it scales better. For low concurrency performance difference is neglible.	8 years ago
Sergey Vojtovich	868c77df3e	MDEV-14756 - Remove trx_sys_t::rw_trx_list Replaced UT_LIST_GET_LEN(trx_sys->rw_trx_list) with trx_sys->rw_trx_hash.size(). Moved freeing of trx objects at shutdown to rw_trx_hash destructor. Small clean-up in trx_rollback_recovered().	8 years ago
Sergey Vojtovich	d09f146934	MDEV-14756 - Remove trx_sys_t::rw_trx_list Reduce divergence between trx_sys_t::rw_trx_hash and trx_sys_t::rw_trx_list by not adding recovered COMMITTED transactions to trx_sys_t::rw_trx_list. Such transactions are discarded immediately without creating trx object. This also required to split rollback and cleanup phases of recovery. To reflect these updates the following renames happened: trx_rollback_or_clean_all_recovered() -> trx_rollback_all_recovered() trx_rollback_or_clean_is_active -> trx_rollback_is_active trx_rollback_or_clean_recovered() -> trx_rollback_recovered() trx_cleanup_at_db_startup() -> trx_cleanup_recovered() Also removed a hack from lock_trx_release_locks(). Instead let recovery rollback thread to skip committed XA transactions.	8 years ago
Igor Babaev	07c0bac039	Fixed mdev-14947 Assertion `0' fails in Field_null::can_optimize_keypart_ref when number of NULLs in IN list reaches in_predicate_conversion_threshold The bug was fixed by removing an assertion that had been set in order just to test whether the code could be ever executed.	8 years ago

Marko Mäkelä	656f66def2	Follow-up fix to MDEV-14585 Automatically remove #sql- tables in InnoDB dictionary during recovery If InnoDB is killed while ALTER TABLE...ALGORITHM=COPY is in progress, after recovery there could be undo log records some records that were inserted into an intermediate copy of the table. Due to these undo log records, InnoDB would resurrect locks at recovery, and the intermediate table would be locked while we are trying to drop it. This would cause a call to row_rename_table_for_mysql(), either from row_mysql_drop_garbage_tables() or from the rollback of a RENAME operation that was part of the ALTER TABLE. row_rename_table_for_mysql(): Do not attempt to parse FOREIGN KEY constraints when renaming from #sql-something to #sql-something-else, because it does not make any sense. row_drop_table_for_mysql(): When deferring DROP TABLE due to locks, do not rename the table if its name already starts with the #sql- prefix, which is what row_mysql_drop_garbage_tables() uses. Previously, the too strict prefix #sql-ib was used, and some tables were renamed unnecessarily.	8 years ago

Sergei Golubchik	715a507e33	MDEV-14786 Server crashes in Item_cond::transform on 2nd execution of SP querying from a view instead of skipping invalid items in setup_conds(), don't pass them into a JOIN at all (test case in versioning.select2)	8 years ago
Sergei Golubchik	1ea2b2956b	Revert "MDEV-14786 Server crashes in Item_cond::transform on 2nd execution of SP querying from a view [fixes #436 ]" This reverts commit `7069071d7d` And add a test to show that optimization steps that a) are repeated for every execution b) create new items cannot be done on the statement arena	8 years ago
Sergei Golubchik	edb6375910	compilation warning on windows	8 years ago
Marko Mäkelä	f44017384a	MDEV-14968 On upgrade, InnoDB reports "started; log sequence number 0" srv_prepare_to_delete_redo_log_files(): Initialize srv_start_lsn.	8 years ago
Alexander Barkov	81378b3947	Moving a change_list related methods from THD to Item_change_list 1. Moving the following methods from THD to Item_change_list: nocheck_register_item_tree_change() check_and_register_item_tree_change() rollback_item_tree_changes() as they work only with the "change_list" member and don't require anything else from THD. 2. Deriving THD from Item_change_list This change will help to fix "MDEV-14603 signal 11 with short stacktrace" easier.	8 years ago
Marko Mäkelä	d87531a6a0	Follow-up to MDEV-14952: Remove some more btr_get_search_latch() Replace some !rw_lock_own() assertions with the stronger !btr_search_own_any(). Remove some redundant btr_get_search_latch() calls. btr_search_update_hash_ref(): Remove a duplicated assertion. btr_search_build_page_hash_index(): Remove a duplicated assertion. rw_lock_s_lock() asserts that the latch is not being held. btr_search_disable_ref_count(): Remove an assertion. The only caller is acquiring all adaptive hash index latches.	8 years ago
Marko Mäkelä	2281fcf38a	Follow-up fix to MDEV-14952 for Mariabackup innodb_init_param(): Initialize btr_ahi_parts=1 for Mariabackup. btr_search_enabled: Let the adaptive hash index be disabled in Mariabackup. This would potentially only matter during --export, and --export performs a table scan, not many index lookups.	8 years ago
Marko Mäkelä	be85c2dc88	Mariabackup --prepare: Do not access transactions or data dictionary innobase_start_or_create_for_mysql(): Only start the data dictionary and transaction subsystems in normal server startup and during mariabackup --export.	8 years ago
Marko Mäkelä	33ecf8345d	Follow-up fix to MDEV-14441: Fix a potential race condition btr_cur_update_in_place(): Read block->index only once, so that it cannot change to NULL after the first read. When block->index != NULL, it must be equal to index.	8 years ago
Otto Kekäläinen	1d522353c8	Deb: wrap-and-sort -a the lib* packages in debian/control This way all the libraries are listed in a logical order and it will later be easier to compare the control file contents to downstream versions.	8 years ago

Otto Kekäläinen	72768cf188	Deb: Warn if sources contain a file that is not installed anywhere	8 years ago
Otto Kekäläinen	b5edb4ca3a	Deb: Add missing files into correct packages and rest in not-installed There was a lot of files generated by the sources that were not installed in any package. This fixes most of those issues, but not all. Files still outside any package are in the not-installed, which is used by dh_install. Also make sure all configuration files are installed to the correct location that matches layout used by Debian official packages.	8 years ago
Otto Kekäläinen	dbc9cfa52b	Deb: .manpages files should only contain man pages unique to deb packages All man pages that stem from the actual sources should be installed along everything else in .install files.	8 years ago
Otto Kekäläinen	711e8c5634	MDEV-12642: Build deb source packages on buildbot, just not on Travis-CI	8 years ago

Otto Kekäläinen	ed00fd2bce	Deb: switch from usr/include/mysql to usr/include/mariadb Matching libmariadb-dev package contents in official Debian repositories, the MariaDB Connector/C files should go into a folder using the 'mariadb' name. For compatibility with sources that expect to find 'mysql' stuff, create a symlink from include/mysql to include/mariadb.	8 years ago
Otto Kekäläinen	5b3bf57be2	Deb: Install missing man pages	8 years ago
Otto Kekäläinen	be59851ad9	Deb: Match official Debian package libmariadb-dev-compat Using this package any source that expects MySQL Client libraries should build without changes. Sources that expect MariaDB Connector C should build using only libmariadb-dev. Current MariaDB Connector/C does not build quite identically in this source tree compared to how it build in Debian official. The remaining differences are tracked in MDEV-14921.	8 years ago
Otto Kekäläinen	9ef2268eda	Deb: Simplify libmariadb.so.3 links No path is required. These files always reside in the same directory anyway.	8 years ago
Otto Kekäläinen	65db816c32	Deb: Split libmysqlclient19/20 compat links into a separate package We already ship libmysqlclient18 that replaces any existing package with the same name and install symlinks that point to out libmariadb.so. Instead of creating more packages, we add just one more that does the same and provides both libmysqlclient19 and -20 replacements symlinks. This is a clean solution, because systems that only use (and are built against) libmariadb will not need them and if somebody has done a mistake in the linker parameters, they will spot it and can easily update the filename to libmariadb.	8 years ago
Otto Kekäläinen	90f1f72622	Deb: Add missing files to packages - tokuft_logprint should be shipped in the TokuDB plugin - mysql_install_db is needed for installing/upgrading the datadir so it must be in the server core package so users can roll their own upgrades	8 years ago
Otto Kekäläinen	503fcfb80f	Deb: Re-remove unnecessary version suffixes from package names There is no point in having version suffixes in plugin packages. They will via their control file anyway depend on the correct server or client version. Having version suffices has no benefit and it just complicates upgrades when a new major version name package needs to replace all possible previous version. This issue was overlooked when merging commit `844a575946` from 10.2 into 10.3, so it needs to be manually fixed now.	8 years ago
Otto Kekäläinen	9719fb4bef	Deb: Re-rename .files into .install The correct format for new Debian packages is to define install lists as *.install files. This has already been fixed for 10.3, but it when merging commit `c5a525bda2` from 10.2, this change was overlooked and a file of the old format slipped in.	8 years ago
Otto Kekäläinen	846517d9b7	Deb: Recover include/mariadb wrongly removed in commit `9b10b4181f` The libmariadb-dev package must include this directory so that downstream developers can intentionally include MariaDB libraries as they want. This matches the contents of the official Debian libmariadb-dev package.	8 years ago
Otto Kekäläinen	094938255d	Deb: sync architecture restrictions from packaging in Debian official	8 years ago
Otto Kekäläinen	e260c6a087	Fix commit `9631d933fb` so Travis CI doesn't fail TokuDB and Mroonga are not built on Travis CI to save time. Previously their packages were not created due to a hack in debian/rules, that got removed in commit `9631d933fb`. This change complements that commit.	8 years ago

Marko Mäkelä	f5e158183c	Follow-up fix to MDEV-14441: Correct a misplaced condition btr_cur_update_in_place(): The call rw_lock_x_lock(ahi_latch) must of course be inside the if (ahi_latch) condition. This is a mistake that I made when backporting the fix-under-development from 10.3.	8 years ago
