Vladislav Vaintroub	4e30a57e6b	MDEV-20839 innodb-redo-badkey fails sporadically	6 years ago
Vladislav Vaintroub	5e62b6a5e0	MDEV-16264 Use threadpool for Innodb background work. Almost all threads have gone - the "ticking" threads, that sleep a while then do some work) (srv_monitor_thread, srv_error_monitor_thread, srv_master_thread) were replaced with timers. Some timers are periodic, e.g the "master" timer. - The btr_defragment_thread is also replaced by a timer , which reschedules it self when current defragment "item" needs throttling - the buf_resize_thread and buf_dump_threads are substitutes with tasks Ditto with page cleaner workers. - purge workers threads are not tasks as well, and purge cleaner coordinator is a combination of a task and timer. - All AIO is outsourced to tpool, Innodb just calls thread_pool::submit_io() and provides the callback. - The srv_slot_t was removed, and innodb_debug_sync used in purge is currently not working, and needs reimplementation.	6 years ago
Vladislav Vaintroub	00ee8d85c9	MDEV-16264: Add threadpool library The library is capable of - asynchronous execution of tasks (and optionally waiting for them) - asynchronous file IO This is implemented using libaio on Linux and completion ports on Windows. Elsewhere, async io is "simulated", which means worker threads are performing synchronous IO. - timers, scheduling work asynchronously in some point of the future. Also periodic timers are implemented.	6 years ago
Vladislav Vaintroub	7e08dd85d6	MDEV-16264 prerequisite patch, ha_preshutdown. This is a prerequisite patch required to remove Innodb's thd_destructor_proxy thread. The patch implement pre-shutdown functionality for handlers. A storage engine might need to perform some work after all user connections are shut down, but before killing off the plugins. The reason is that an SE could still be using some of the server infrastructure. In case of Innodb this would be purge threads, that call into the server to calculate results of virtual function, acquire MDL locks on tables, or possibly also use the audit plugins.	6 years ago
Vladislav Vaintroub	e7549917e1	MDEV-16264 - prerequisite patch - true background THDs Create background THDs that are not counted, and do not block close_connections(), in other words they are just something that plugin can use internally. These THD will be used later by Innodb purge threads, and they need THD to calculate virtual functions.	6 years ago
Vladislav Vaintroub	2fb23b896e	MDEV-16264 prerequisite patch, enable thr_timer in embedded Since threadpool is using thr_timer, and it also exist in embedded version, initialize timer also in embedded version	6 years ago
Vladislav Vaintroub	ad17c98dd5	MDEV-16264 - prerequisite patch, periodic thr_timer Threadpool will need a functionality for periodic thr_timer (the threadpool maintainence task is a timer that runs periodically). Also increase the stack size for the timer thread, 8k won't be enough.	6 years ago

Jean Weisbuch	c454b8964c	MDEV-4476: mytop tracker - Added dynamic column width fro `user` and `db` columns - Added option `%` to hide the progress - Follow up changes from Ubuntu - Take `INFORMATION_SCHEMA.PROCESSLIST` into account to determine progress of the `actual stage` - Indentation fixes Closes #215	6 years ago
Marko Mäkelä	3d4a801533	MDEV-12353 preparation: Replace mtr_x_lock() and friends Apart from page latches (buf_block_t::lock), mini-transactions are keeping track of at most one dict_index_t::lock and fil_space_t::latch at a time, and in a rare case, purge_sys.latch. Let us introduce interfaces for acquiring an index latch or a tablespace latch. In a later version, we may want to introduce mtr_t members for holding a latched dict_index_t* and fil_space_t, and replace the remaining use of mtr_t::m_memo with std::set<buf_block_t> or with a map<buf_block_t,byte> pointing to log records.	6 years ago
Marko Mäkelä	4ded5fb9ac	MDEV-20949: Merge 10.2 into 10.3 In the test innodb.instant_alter,4k we would be flagging an error for too large row size. That error was previously only being reported if the table was being rebuilt. Thus, this merge is fixing a small omission in MDEV-11369 (instant ADD COLUMN).	6 years ago

Sujatha	caa79081c3	MDEV-20707: Missing memory barrier in parallel replication error handler in wait_for_prior_commit() revision-id: `673e253724` Author: Kristian Nielsen Fix missing memory barrier in wait_for_commit. The function wait_for_commit::wait_for_prior_commit() has a fast path where it checks without locks if wakeup_subsequent_commits() has already been called. This check was missing a memory barrier. The waitee thread does two writes to variables `waitee' and `wakeup_error', and if the waiting thread sees the first write it _must_ also see the second or incorrect behavior will occur. This requires memory barriers between both the writes (release semantics) and the reads (acquire semantics) of those two variables. Other accesses to these variables are done under lock or where only one thread will be accessing them, and can be done without barriers (relaxed semantics).	6 years ago

Marko Mäkelä	49019dde65	MDEV-17138 follow-up: Optimize index page creation btr_create(), btr_root_raise_and_insert(): Write a MLOG_MEMSET record to set FIL_PAGE_PREV,FIL_PAGE_NEXT to FIL_NULL, instead of writing two MLOG_4BYTES records. For ROW_FORMAT=COMPRESSED pages, we will not use MLOG_MEMSET because we want the crash-downgrade to earlier 10.4 releases to succeed. mlog_parse_nbytes(): Relax the too strict assertion. There is no problem with MLOG_MEMSET records that affect the uncompressed header of ROW_FORMAT=COMPRESSED index pages.	6 years ago
Sergei Petrunia	d4edb0510e	MDEV-20646: 10.3.18 is slower than 10.3.17 Fix incorrect change introduced in the fix for MDEV-20109. The patch tried to compute a more precise estimate for the record_count value in SJ-Materialization-Scan strategy (in Sj_materialization_picker::check_qep). However the new formula is worse as it produces extremely optimistic results in common cases where SJ-Materialization-Scan should be used) The old formula produces pessimistic results in cases when Sj-Materialization- Scan is unlikely to be a good choice anyway. So, the old behavior is better.	6 years ago
Eugene Kosov	98694ab0cb	MDEV-20949 Stop issuing 'row size' error on DML Move row size check to early CREATE/ALTER TABLE phase. Stop checking on table open. dict_index_add_to_cache(): remove parameter 'strict', stop checking row size dict_index_t::record_size_info_t: this is a result of row size check operation create_table_info_t::row_size_is_acceptable(): performs row size check. Issues error or warning. Writes first overflow field to InnoDB log. create_table_info_t::create_table(): add row size check dict_index_t::record_size_info(): this is a refactored version of dict_index_t::rec_potentially_too_big(). New version doesn't change global state of a program but return all interesting info. And it's callers who decide how to handle row size overflow. dict_index_t::rec_potentially_too_big(): removed	6 years ago

Marko Mäkelä	abd45cdc38	MDEV-20934: Correct a debug assertion A search with PAGE_CUR_GE may land on the supremum record on a leaf page that is not the rightmost leaf page. This could occur when all keys on the current page are smaller than the search key, and the smallest key on the successor page is larger than the search key. ibuf_delete_recs(): Correct the debug assertion accordingly.	6 years ago

Sergei Petrunia	68ed3a81f2	MDEV-20854: ANALYZE for statements: not clear where the time is spent Count the "gap" time between table accesses and display it as r_other_time_ms in the "table" element. * The advantage of this approach is that it doesn't add any new my_timer_cycles() calls. * The disadvantage is that the definition of what is done during "other time" is not that clear: it includes checking the WHERE (for this table), constructing index lookup tuple (for the next table) writing to GROUP BY temporary table (as we dont account for that time separately [yet], etc)	6 years ago
Sujatha	7df07c7666	MDEV-20953: binlog_encryption.rpl_corruption failed in buildbot due to wrong error code Problem: ======== CURRENT_TEST: binlog_encryption.rpl_corruption mysqltest: In included file "./include/wait_for_slave_io_error.inc": ... At line 72: Slave stopped with wrong error code ** Slave stopped with wrong error code: 1743 (expected 1595,1913) ** Analysis: ======== The test emulates the corruption at the various stages of replication for example in binlog file, in network and in relay log etc. It verifies that all corruption cases are handled through appropriate error messages. The test cases which emulate network failure expect following errors. --ER_SLAVE_RELAY_LOG_WRITE_FAILURE (1595) --ER_NETWORK_READ_EVENT_CHECKSUM_FAILURE (1743) Ideally test should expect error codes as 1595 and 1743. But the test actually waits on incorrect error code 1595,1913 Fix: === Added appropriate error code for 'ER_NETWORK_READ_EVENT_CHECKSUM_FAILURE'. Replaced 1913 with 1743.	6 years ago
Eugene Kosov	e5f99a0c0c	MDEV-20297 Support C++11 range-based for loop for List<T> New iterator has the fastest possible implementation: just moves one pointer. It's faster that List_iterator and List_iterator_fast: both do more on increment. Overall patch brings: 1) work compile times 2) possibly(!) worse debug build performance 3) definitely better optimized build performance 4) ability to write less code 5) ability to write less bug-prone code	6 years ago
