* A more dynamic binlog format which allows small changes (1064) * Log session variables in Query_log_event (1063) It contains a few bugfixes (which I made when running the testsuite). I carefully updated the results of the testsuite (i.e. I checked for every one, if the difference between .reject and .result could be explained). Apparently mysql-test-run --manager is broken in 4.1 and 5.0 currently, so I could neither run the few tests which require --manager, nor check that they pass nor modify their .result. But for builds, we don't run with --manager. Apart from --manager, the full testsuite passes, with Valgrind too (no errors). I'm going to push in the next minutes. Remains: update the manual. Note: by chance I saw that (in 4.1, in 5.0) rpl_get_lock fails when run alone; this is normal at it makes assumptions on thread ids. I will fix this one day in 4.1. mysql-test/r/rpl000015.result: result update mysql-test/r/rpl_change_master.result: result update mysql-test/r/rpl_error_ignored_table.result: result update mysql-test/r/rpl_flush_log_loop.result: result update mysql-test/r/rpl_flush_tables.result: result update mysql-test/r/rpl_loaddata.result: result update mysql-test/r/rpl_loaddata_rule_m.result: result update mysql-test/r/rpl_loaddata_rule_s.result: result update mysql-test/r/rpl_log.result: result update mysql-test/r/rpl_log_pos.result: result update mysql-test/r/rpl_max_relay_size.result: result update mysql-test/r/rpl_relayrotate.result: result update mysql-test/r/rpl_replicate_do.result: result update mysql-test/r/rpl_reset_slave.result: result update mysql-test/r/rpl_rotate_logs.result: result update mysql-test/r/rpl_session_var.result: result update mysql-test/r/rpl_temporary.result: result update mysql-test/r/rpl_trunc_binlog.result: result update mysql-test/r/rpl_until.result: result update mysql-test/r/rpl_user_variables.result: result update mysql-test/t/rpl000010-slave.opt: need to wait 2 events, because now we receive a Format_desc on top of the Rotate, when replication starts. mysql-test/t/rpl000015.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_change_master.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_empty_master_crash.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_error_ignored_table.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_flush_log_loop.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_loaddata.test: position update mysql-test/t/rpl_loaddata_rule_m.test: position update mysql-test/t/rpl_loaddata_rule_s.test: position update mysql-test/t/rpl_log.test: position update mysql-test/t/rpl_log_pos.test: position update mysql-test/t/rpl_max_relay_size.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_openssl.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_redirect.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_relayrotate-slave.opt: better options for this test mysql-test/t/rpl_relayrotate.test: using max() is better for debugging (it shows at which place the slave SQL thread resumed) mysql-test/t/rpl_replicate_do.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_reset_slave.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_rotate_logs.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_session_var.test: 100 because password() is longer than 10 chars mysql-test/t/rpl_trunc_binlog.test: relay log information is not repeatable in general (if a reconnection happens because --sleep=10 for example), so we hide these columns. mysql-test/t/rpl_until.test: position update mysql-test/t/rpl_user_variables.test: position update sql/log.cc: Ensure that the Format_desc propagated on next relay logs does not trigger undue actions (like incrementing some positions or clearing some files). sql/log_event.cc: * When the slave SQL thread finds a Rotate/Format_desc/Stop in the middle of a transaction (then these were written by the slave itself to its relay log), it should not increment rli->group* variables, but only rli->event* ones. * When the slave SQL thread finds a Format_desc not to be ignored (not the same server id as the slave's), if it has log_pos==0 it must not trigger "unfinished transaction in master's binlog" (log_pos==0 is always a marker in the relay log to mean "this event was not at this place in the master's binlog": it's for fake Rotate events, and for Format_description events which the master had to send us for replication to start). * In the Query_log_event on disk, catalog is now terminated by '\0'. * thd->catalog must be set to 0 when some exec_event() terminate (otherwise double free). sql/slave.cc: * Fixes for a few bugs when ignoring events in the slave SQL thread: - do not decrement rli->slave_skip_counter if the event is an event related to the binlog or relay log itself (FORMAT_DESCRIPTION, ROTATE, STOP) because these events should never be skipped (or the slave will be confused). Usually the user wants to skip a query, not a Rotate... - when we (re)connect to the master, we must free description_event_for_queue (otherwise memory leak when we reconnect). * Changed a bit the code where we change description_event_for_queue, to make it look "safer". * Moved 'created=0' to log.cc where it is safer. * When the slave SQL thread finds a Rotate/Format_desc/Stop in the middle of a transaction (then these were written by the slave itself to its relay log), it should not increment rli->group* variables, but only rli->event* ones. sql/sql_class.h: a warning comment sql/sql_repl.cc: A mistake: I had passed a char* instead of char**

|
# binlog (e.g. a temporary table in the previous test has not

|
# been explicitly deleted, and at the beginning of the current

# test the slave immediately writes DROP TEMPORARY TABLE this_old_table).

# We are going to read the slave's binlog which contains file_id (for some LOAD

|
# to stop and start the slave, to be sure file_id will start from 1.
|
|
# This can be done with 'server_stop slave', but
|
|
# this would require the manager, so most of the time the test will be skipped
|
|
# :(
|
|
# To workaround this, I (Guilhem) add a (empty) rpl_log-slave.opt (because when
|
|
# mysql-test-run finds such a file it restarts the slave before doing the
|
|
# test). That's not very elegant but I could find no better way, sorry.

# We need an extra update before doing save_master_pos.
|
|
# Otherwise, an unlikely scenario may occur:
|
|
# * When the master's binlog_dump thread reads the end of master-bin.001,
|
|
# it send the rotate event which is at this end, plus a fake rotate event
|
|
# because it's starting to read a new binlog.

# save_master_pos will record the position of the first of the two rotate

# * Later the slave waits for the position of the first rotate event,
|
|
# and it may quickly stop (in 'slave stop') without having received the fake
|
|
# one.

# So, depending on a few milliseconds, we end up with 2 rotate events in the
