unknown	010971a761	MDEV-6156: Parallel replication incorrectly caches charset between worker threads Replication caches the character sets used in a query, to be able to quickly reuse them for the next query in the common case of them not having changed. In parallel replication, this caching needs to be per-worker-thread. The code was not modified to handle this correctly, so the caching in one worker could cause another worker to run a query using the wrong character set, causing replication corruption.	12 years ago
Sergey Vojtovich	b123249010	MDEV-5792 - Deadlock between SELECTs from METADATA_LOCK_INFO and another I_S table mdl_iterate() helper function (which is used by the plugin to iterate mdl locks) acquired mutexes in reverse order. Fixed by iterating MDL locks in two stages: 1. Iterate locks hash under the protection of hash mutex, store all lock pointers in a thread local array and increment reference counter for the lock. 2. Iterate local array without protection of hash mutex, handle destroyed locks. It somewhat echoes hack in MDL_map_partition::move_from_hash_to_lock_mutex.	12 years ago

Igor Babaev	3e0f63c18f	Fixed the problem of mdev-5947. Back-ported from the mysql 5.6 code line the patch with the following comment: Fix for Bug#11757108 CHANGE IN EXECUTION PLAN FOR COUNT_DISTINCT_GROUP_ON_KEY CAUSES PEFORMANCE REGRESSION The cause for the performance regression is that the access strategy for the GROUP BY query is changed form using "index scan" in mysql-5.1 to use "loose index scan" in mysql-5.5. The index used for group by is unique and thus each "loose scan" group will only contain one record. Since loose scan needs to re-position on each "loose scan" group this query will do a re-position for each index entry. Compared to just reading the next index entry as a normal index scan does, the use of loose scan for this query becomes more expensive. The cause for selecting to use loose scan for this query is that in the current code when the size of the "loose scan" group is one, the formula for calculating the cost estimates becomes almost identical to the cost of using normal index scan. Differences in use of integer versus floating point arithmetic can cause one or the other access strategy to be selected. The main issue with the formula for estimating the cost of using loose scan is that it does not take into account that it is more costly to do a re-position for each "loose scan" group compared to just reading the next index entry. Both index scan and loose scan estimates the cpu cost as: "number of entries needed too read/scan" * ROW_EVALUATE_COST The results from testing with the query in this bug indicates that the real cost for doing re-position four to eight times higher than just reading the next index entry. Thus, the cpu cost estimate for loose scan should be increased. To account for the extra work to re-position in the index we increase the cost for loose index scan to include the cost of navigating the index. This is modelled as a function of the height of the b-tree: navigation cost= ceil(log(records in table)/log(indexes per block)) * ROWID_COMPARE_COST; This will avoid loose index scan being used for indexes where the "loose scan" group contains very few index entries.	12 years ago

Alexander Barkov	fbfa004327	MDEV-6170 Incorrect ordering with utf8_bin and utf8mb4_bin collations	12 years ago
unknown	64923bb653	MDEV-6156: Parallel replication incorrectly caches charset between worker threads The previous patch for this bug was unfortunately completely wrong. The purpose of cached_charset is to remember which character set we have installed currently in the THD, so that in the common case where charset does not change between queries, we do not need to update it in the THD. Thus, it is important that the cached_charset field is tightly coupled to the THD for which it handles caching. Thus the right place to put cached_charset seems to be in the THD. This patch introduces a field THD:system_thread_info where such info in general can be placed without further inflating the THD with unused data for other threads (THD is already far too big as it is). It then moves the cached_charset into this slot for the SQL driver thread and for the parallel replication worker threads. The THD::rpl_filter field is also moved inside system_thread_info, to keep the size of THD unchanged. Moving further fields in to reduce the size of THD is a separate task, filed as MDEV-6164.	12 years ago
