Report claims that Seconds_behind_master behaves unexpectedly. Code analysis shows that there is an evident flaw in that treating of FormatDescription event is wrong so that after FLUSH LOGS on slave the Seconds_behind_master's calculation slips and incorrect value can be reported to SHOW SLAVE STATUS. Even worse is that the gap between the correct and incorrect deltas grows with time. Fixed with prohibiting changes to rpl->last_master_timestamp by artifical events (any kind of). suggestion as comments is added how to fight with lack of info on the slave side by means of new heartbeat feature coming. The test can not be done ealily fully determistic. sql/log_event.cc: changing timestamp is affirmed only by non-artificial events. Artifical FD won't change it anymore. The simulation code is off unless server is started with the args from the opt-file. The simulation code assumes that it will execute specific schedule generated by rpl_replication_delay.test. sql/slave.cc: Comments are changed to announce a new possibility to cope with Seconds_behind_master jumping due to EOF special treatment (reset of the timestamp) mysql-test/suite/manual/r/rpl_replication_delay.result: result are not deterministic though there are comments saying the most probable expected value for Seconds_behind_master mysql-test/suite/manual/t/rpl_replication_delay-slave.opt: bug emulation mysql-test/suite/manual/t/rpl_replication_delay.test: specic test for bug#29309. It's hard to make it reliable as it deals with timestamps. (a way to automate the test like this is to have I_S table for show slave status' fields) A possible way to check results is to run grep -i 'show\|seconds' < suite/manual/r/rpl_replication_delay.reject and to get the lines like these: show slave status /* Second_behind reports 0 */;; Seconds_Behind_Master 0 show slave status /* bug emulated: reports slave threads starting time about 3*3 not 3 secs */;; Seconds_Behind_Master 9 show slave status /* reports the correct diff with master query time about 3+3 secs */;; Seconds_Behind_Master 6 Due to time discreteness of time the reported numbers may slightly vary. That's why the test is not reliable.

Problem: one thread could read uninitialized memory from (the stack of) another thread. Fix: swapped order of initializing the memory and making it available to the other thread. Fix: put lock around the statement that makes the memory available to the other thread. Fix: all fields of the struct are now initialized in the constructor, to avoid future problems. sql/sql_class.h: Initialize all members in constructor for more safe future code. sql/sql_repl.cc: Swap order so that linfo is first initialized, then assigned, instead of the other way around. Put a lock around the assignment. We use LOCK_thread_count since log_in_use uses it: log_in_use may be running concurrently, called from MYSQL_LOG::purge_logs.

Problem: some valid euc-kr characters were rejected because condition checking multi-byte tail didn't allow multi-byte characters having the second byte in the ranges [0x41..0x5A] and [0x61..0x7A].

active_mi has been reset (shutdown) at the time of quering with SHOW SLAVE STATUS so that at handling of SHOW an attempt to read its members segfaults. Fixed with checking the value of active_mi before to call show_master_info() Merely send_ok() is invoked when active_mi does not exist. A test can not be easiely written. Notice, there are more analogical cases in the code which require a similar treatment (to be reported as a bug separately). sql/sql_parse.cc: Ignore reporting and send only OK if master info struct has been destoyed. As this must be at shutdown merely a warning is sent to the client.

The optimizer sets index traversal in reverse order only if there are used key parts that are not compared to a constant. However using the primary key as an ORDER BY suffix rendered the check incomplete : going in reverse order must still be used even if all the parts of the secondary key are compared to a constant. Fixed by relaxing the check and set reverse traversal even when all the secondary index keyparts are compared to a const. Also account for the case when all the primary keys are compared to a constant. mysql-test/r/innodb_mysql.result: Bug #31001: test case mysql-test/t/innodb_mysql.test: Bug #31001: test case sql/sql_select.cc: Bug #31001: - account for the case when all the primary key parts are compared to a constant - force test_if_skip_sort_order to go backwards over the key even when the number of keyparts used is the same as the number of keyparts equal to a constant. (because of the primary key suffix).

- The bug was caused by COUNT(DISTINCT ...) code using Unique object in a way that assumed that BIT(N) column occupies a contiguous space in temp_table->record[0] buffer. - The fix is to make COUNT(DISTINCT ...) code instruct create_tmp_table to create temporary table with column of type BIGINT, not BIT(N). mysql-test/r/type_bit.result: BUG#30324: Grouping queries with COUNT(DISTINCT bit column) return wrong results - Testcase mysql-test/t/type_bit.test: BUG#30324: Grouping queries with COUNT(DISTINCT bit column) return wrong results - Testcase sql/item_sum.cc: BUG#30324: Grouping queries with COUNT(DISTINCT bit column) return wrong results - Make COUNT(DISTINCT ...) code instruct create_tmp_table to create temporary table with BIGINT, not BIT(N) column.

Declaring an all space column name in the SELECT FROM DUAL or in a view leads to misleading warning message: "Leading spaces are removed from name ' '". The Item::set_name method has been modified to raise warnings like "Name ' ' has become ''" in case of the truncation of an all space identifier to an empty string identifier instead of the "Leading spaces are removed from name ' '" warning message. sql/item.cc: Fixed bug #27695. The Item::set_name method has been modified to raise warnings like "Name ' ' has become ''" in case of the truncation of an all space identifier to an empty string identifier instead of the "Leading spaces are removed from name ' '" warning message. sql/share/errmsg.txt: Fixed bug #27695. mysql-test/t/select.test: Added test case for bug #27695. mysql-test/r/select.result: Added test case for bug #27695.
