Rotate_log_event::exec_event() believed that the relay log was corrupted. Fixed it
by moving the test for corruption to Start_log_event::exec_event().
Changed Rotate_log_event::exec_event() to not increment positions when the
event is seen in the middle of a transaction.
I did a separate commit in 4.1 (so this should not be merged to 4.0) because
code is a bit different in 4.1.
A test to see if the slave detects when the master died while writing a
transaction to the binlog (uses a forged truncated binlog I made).
Add quoting for use `database` for mysqlbinlog
Removed test ins0000001
Add support for --replace for exec in mysqltest
Don't refer to install dir in mysqlbinlog.result
Bug #1392 "On Win, slave leaves one temp file after successf. replicating LOAD DATA INFILE"
Windows-specific bug (we forgot to close a file before deleting it).
Patch written by me, tested by Miguel (thanks!) and it works.
when the SQL thread stops, set rli->inside_transaction to 0. This is needed if the user
later restarts replication from a completely different place where there are only autocommit
statements.
* Detect the case where the master died while flushing the binlog cache to the binlog
and stop with error. Cannot add a testcase for this in 4.0 (I tested it manually)
as the slave always runs with --skip-innodb.
fix for BUG#1113 "INSERT into non-trans table SELECT ; ROLLBACK" does not send warning"
and
fix for BUG#873 "In transaction, INSERT to non-trans table is written too early to binlog".
Now we don't always write the non-trans update immediately to the binlog;
if there is something in the binlog cache we write it to the binlog cache
(because the non-trans update could depend on a trans table which was modified
earlier in the transaction); then in case of ROLLBACK, we write the binlog
cache to the binlog, wrapped with BEGIN/ROLLBACK.
This guarantees that the slave does the same updates.
For ROLLBACK TO SAVEPOINT: when we execute a SAVEPOINT command we write it
to the binlog cache. At ROLLBACK TO SAVEPOINT, if some non-trans table was updated,
we write ROLLBACK TO SAVEPOINT to the binlog cache; when the transaction
terminates (COMMIT/ROLLBACK), the binlog cache will be flushed to the binlog
(because of the non-trans update) so we'll have SAVEPOINT and ROLLBACK TO
SAVEPOINT in the binlog.
Apart from this rare case of updates of mixed table types in transaction, the
usual way is still clear the binlog cache at ROLLBACK, or chop it at
ROLLBACK TO SAVEPOINT (meaning the SAVEPOINT command is also chopped, which
is fine).
Note that BUG#873 encompasses subbugs 1) and 2) of BUG#333 "3 binlogging bugs when doing INSERT with mixed InnoDB/MyISAM".
"LOAD DATA INFILE is badly filtered by binlog-*-db rules".
There will probably be a second final one to merge Dmitri's changes
to rpl_log.result and mine.
2 new tests:
rpl_loaddata_rule_m : test of logging of LOAD DATA INFILE when the master has binlog-*-db rules,
rpl_loaddata_rule_s : test of logging of LOAD DATA INFILE when the slave has binlog-*-db rules and --log-slave-updates.
log-slave-updates since this causes unexpected values in
Exec_master_log_pos in A->B->C replication setup, synchronization
problems in master_pos_wait()...
Still this brokes some functionality in sql/repl_failsafe.cc
(but this file is not used now)
the first 4 bytes of the relay log. Indeed comments in mysys/mf_iocache.c
say we must always use my_b_append for such a cache.
This *could* avoid a very rare assertion failure which is:
030524 19:32:38 Slave SQL thread initialized, starting replication in log 'FIRST' at position 0, relay log '/
users/gbichot/4.1.1/mysql-test/var/log/slave-relay-bin.000001' position: 4
030524 19:32:38 next log '/users/gbichot/4.1.1/mysql-test/var/log/slave-relay-bin.000002' is currently active
mysqld: mf_iocache.c:701: _my_b_seq_read: Assertion `pos_in_file == info->end_of_file' failed.
and which seemed to happen always when the SQL thread and/or the I/O thread
were at position 4 in a relay log.
I extended the task to cleaning error messages, making them look nicer,
and making the output of SHOW SLAVE STATUS (column Last_error) be as complete
as what's printed on the .err file;
previously we would have, for a failure of a replicated LOAD DATA INFILE:
- in the .err, 2 lines:
"duplicate entry 2708 for key 1"
"failed loading SQL_LOAD-5-2-2.info"
- and in SHOW SLAVE STATUS, only:
"failed loading SQL_LOAD-5-2-2.info".
Now SHOW SLAVE STATUS will contain the concatenation of the 2 messages.
BUG#797 "If query ignored on slave (replicate-ignore-table) the slave still checks if
the returned error (0) is the same as the one on the master, whereas it shouldn't
test this.
Plus a new test for BUG#797.
as the already-stored timestamp. Now 'created' is used only to know if
this is a first binlog or not. And we may re-use the superfluous bytes
in 5.0 when we need room.
we now make a distinction between if the master is < 3.23.57, 3.23 && >=57, and 4.x
(before the 2 3.23 were one). This is because in 3.23.57 we have a way to distinguish between
a Start_log_event written at server startup and one written at FLUSH LOGS, so we
have a way to know if the slave must drop old temp tables or not.
Change: mi->old_format was bool, now it's enum (to handle 3 cases). However, functions
which had 'bool old_format' as an argument have their prototypes unchanged, because
the old old_format == 0 now corresponds to the enum value BINLOG_FORMAT_CURRENT which
is equal to 0, so boolean tests are left untouched. The only case were we use mi->old_format
as an enum instead of casting it implicitly to a bool, is in Start_log_event::exec_event,
where we want to distinguish between the 3 possible enum values.
Bug 571: play LOAD DATA INFILE the same way on the slave as it was on the master:
if it was with IGNORE, do it with IGNORE,
if it was with REPLACE, do it with REPLACE,
and (the change) if it was with nothing, do it with nothing (not with IGNORE !!).
Bug 573: print a proper error message in case of duplicate entry in LOAD DATA INFILE
on the slave, i.e. a message where the keyname and key value appear :
'Duplicate entry '1' for key 1' and not 'Duplicate entry '%-.64s' for key %d'
(3.23 master, 4.0 slave.
Slave loss temp tables everytime FLUSH LOGS on master).
This fix is less bad than the bug, it will cause a problem only maybe
if the master dies the hard way (I say maybe because I could not
cause a problem, and I don't see how it could happen).
logged, but read as LOAD DATA INFILE REPLACE"
This was just bad && instead of &, but nasty consequences.
This should be merged to 4.0 BUT it will not be automatic (some code
has moved from log_event.h to log_event.cc, and log_event.cc has changed);
please Merging Man, do 'bk grep REPLACE_FLAG' in 4.0/sql
to find all the new places.
