Sujatha Sivakumar	14544cefc9	Bug#18432495:RBR REPLICATION SLAVE CRASHES WHEN DELETE NON-EXISTS RECORDS Problem: ======== In RBR replication, master deletes a record but the record don't exist on slave. when slave tries to apply the Delete_row_log_event from master, it will result in an assert on slave. Analysis: ======== This problem exists not only with Delete_rows event but also with Update_rows event as well. Trying to update a non existing row on the slave from the master will cause the same assert. This assert occurs only for the tables that doesn't have primary keys and which basically require sequential scan to be done to locate a record. This bug occurs only with innodb engine not with myisam. When update or delete rows is executed on a slave on a table which doesn't have primary key the updated record is stored in a buffer named table->record[0] and the same is copied to table->record[1] so that during sequential scan table->record[0] can reloaded with fetched data from the table and compared against table->record[1]. In a special case where there is no record on the slave side scan will result in EOF in that case we reinit the scan and we try to compare record[0] with record[1] which are basically the same. This comparison is incorrect. Since they both are the same record_compare() will report that record is found and we try to go ahead and try to update/delete non existing row. Ideally if the scan results in EOF means no data found hence no need to do a record_compare() at all. Fix: === Avoid comparision of records on EOF. sql/log_event.cc: Avoid record comparison on end of file. sql/log_event_old.cc: Avoid record comparison on end of file.	12 years ago

Annamalai Gurusami	b5299f3559	Bug #18806829 OPENING INNODB TABLES WITH MANY FOREIGN KEY REFERENCES IS SLOW/CRASHES SEMAPHORE Problem: There are 2 lakh tables - fk_000001, fk_000002 ... fk_200000. All of them are related to the same parent_table through a foreign key constraint. When the parent_table is loaded into the dictionary cache, all the child table will also be loaded. This is taking lot of time. Since this operation happens when the dictionary latch is taken, the scenario leads to "long semaphore wait" situation and the server gets killed. Analysis: A simple performance analysis showed that the slowness is because of the dict_foreign_find() function. It does a linear search on two linked list table->foreign_list and table->referenced_list, looking for a particular foreign key object based on foreign->id as the key. This is called two times for each foreign key object. Solution: Introduce a rb tree in table->foreign_rbt and table->referenced_rbt, which are some sort of index on table->foreign_list and table->referenced_list respectively, using foreign->id as the key. These rbt structures will be solely used by dict_foreign_find(). rb#5599 approved by Vasil	12 years ago
