WL#7266: Dump-thread additional concurrency tests This worklog aims at testing the two following scenarios: 1) Whenever the mysql_binlog_send method (dump thread) reaches the end of file when reading events from the binlog, before checking if it should wait for more events, there was a test to check if the file being read was still active, i.e, it was the last known binlog. However, it was possible that something was written to the binary log and then a rotation would happen, after EOF was detected and before the check for active was performed. In this case, the end of the binary log would not be read by the dump thread, and this would cause the slave to lose updates. This test verifies that the problem has been fixed. It waits during this window while forcing a rotation in the binlog. 2) Verify dump thread can send events in active file, correctly after encountering an IO error.

AND 'KILL SESSION' LEAD TO CRASH Analysis: -------- This situation occurs when the connection executes query "show engine innodb status" and this connection is killed by executing statement "kill <con>" by another connection. In function "innodb_show_status", function "stat_print" is called to print the status but return value of function is not checked. After killing connection, if write to connection fails then error is returned and same is set in Diagnostic area. Since FALSE is returned from "innodb_show_status" now, assert to check no error is set in function "set_eof_status" (called from my_eof) is failing. Fix: ---- Changed code to check return value of function "stat_print" in "innodb_show_status".

ha_innobase::records_in_range() should return HA_POS_ERROR for the table during discarded without requesting pages. The later other handler method should treat the error correctly. Approved by Sunny in rb#3433

Description: ------------ There are 2 issues reported in the bug report, 1. One session running a "long" select, then, from the other session, you kill that first one, while select is running, and it receives that message "Server shutdown in progress". Reported Date: 02-Apr-2006 => Looks like this isuse is already fixed in 2009 by the patch pushed for bug28141. 2. Killing query which goes to filesort, logs error entries like: 120416 9:17:28 [ERROR] mysqld: Sort aborted: Server shutdown in progress 120416 9:18:48 [ERROR] mysqld: Sort aborted: Server shutdown in progress 120416 9:19:39 [ERROR] mysqld: Sort aborted: Server shutdown in progress Reported Date: 16-Apr-2012 => This issue is introduced in 5.5+ versions. Fixing this issue in this patch. Analysis: --------- In function "filesort()", on error we are logging error message. To the error message, the message related THD::killed_errno is also appeneded, if it is set.(THD::kill_errno value is obtained by calling member function THD::killed_errno) In the scenario mentioned in this bug report, when we kill the connection, THD::kill_errno is set to the THD::KILL_CONNECTION. Enum type THD::KILL_CONNECTION corressponds to value ER_SERVER_SHUTDOWN. Because of this, "Server shutdown in ...." is appended to the message logged. Fix: ---- Modified code of "filesort()" function to append "KILL_QUERY" status to error message when thread is killed and server shutdown is not in progress.

INDEX_READ_MAP HAD NO MATCH If index_read_map is called for exact search and no matching records exists it will position the cursor on the next record, but still having the relative position to BTR_PCUR_ON. This will make a call for index_next to read yet another next record, instead of returning the record the cursor points to. Fixed by setting pcur->rel_pos = BTR_PCUR_BEFORE if an exact [prefix] search is done, but failed. Also avoids optimistic restoration if rel_pos != BTR_PCUR_ON, since btr_cur may be different than old_rec. rb#3324, approved by Marko and Jimmy

As this mysql_install_db.pl file has always generated lots of confusion on Windows. This fix will make sure to get it removed only from Windows

Changed to try to extend log buffer instead of crash, when log size is too large for the size. Approved by Marko in rb#3229

The testcase for this bug fails randomly due to two reasons. 1. Due to ibuf merge happening background 2. Due to dict stats update which brings the evicted page back into buffer pool. Fix ibuf_contract_ext() to not do any merges with ibuf_debug enabled and also changed dict_stats_update() to return fake statistics without bringing the secondary index pages into buffer pool. Approved by Marko. rb#3419

DURING INNODB RECOVERY Problem: ======= The connection 'master' is dropped by mysqltest after rpl_end.inc. At this point, dropping temporary tables at the connection 'master' are not synced at slave. So, the temporary tables replicated from master remain on slave leading to an inconsistent close of the test. The following test thus complains about the presence of temporary table(s) left over from the previous test. Fix: === - Put explicit drop commands in replication tests so that the temporary tables are dropped at slave as well. - Added the check for Slave_open_temp_tables in mtr_check.sql to warn about the remaining temporary table, if any, at the close of a test.

RPL_SEMI_SYNC_MASTER_ENABLED OFF. Problem: ======= If master is waiting for a reply from slave, at this time set global rpl_semi_sync_master_enabled=OFF, the master server will crash. Analysis: ======== When master is waiting for a reply from slave, at this time if semi sync is switched off on master, during switch off if active transactions are present the transactions will be cleared and "active_tranxs_" variable will be set to NULL. When the waiting master connection finds that semi sync is switched of it tries to access "active_tranxs_" without checking if the transaction list exists or not. Accessing NULL transaction list causes the crash. Fix: === A check has been added to see a valid list exists before accessing the "active_tranxs_". plugin/semisync/semisync_master.cc: Added check for the existence of valid 'active_transx_'.

IT IS DONE IN-PLACE With change buffer enabled, InnoDB doesn't write a transaction log record when it merges a record from the insert buffer to an secondary index page if the insertion is performed as an update-in-place. Fixed by logging the 'update-in-place' operation on secondary index pages. Approved by Marko. rb#2429

WITH MY_B_VPRINTF() Issue : In LP 64 machine max long value can be 20 digit decimal value. But in my_b_vprintf() the intermediate buffer storage used is 17 bytes length. This will lead to buffer overflow. Solution : Increased the buffer storage from 17 to 32 bytes. code is backported from 5.6 mysys/mf_iocache2.c: In function my_b_vprintf increased the size of local buff from 17 to 32 bytes.
