port number can be different from 3306 when doing the release builds
with Do-compile, therefore it has to be replaced with the correct
value during the test run using the "--replace_result" function.
ChangeSet was not sufficient to get the full ChangeLog between two
released versions (when using "--changelog=last") as merging between
trees also merges the BK tags. Now we explicitely search for the last
tagged ChangeSet that matches our major+minor version number, which
should match the last ChangeSet used for the previous release.
"mysqlhotcopy fails to copy tables but does not indicate a failure"
("does not indicate a failure");
this is about "mysqlhotcopy fails to copy tables".
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.
A cosmetic change: set trx id to zero at creation so that SHOW INNODB STATUS does not print a random value for the id of a transaction object for which the transaction has never been started yet (for example, running SHOW INNODB STATUS as the first command from a mysql prompt printed a random id for the trx object associated with the session itself running the SHOW INNODB STATUS command)
Fix bug: if a DELETE failed in a FOREIGN KEY error and it had already deleted some rows, then MySQL did not roll back the failed SQL statement, and also wrote it to the binlog
In background loop run purge to completion before doing other background operations: it does not make sense to flush buffer pool pages if they are soon modified again by purge
trx0purge.c:
Increase purge_sys->n_pages_handled for every undo log we purge, even if that log would be only a hundred bytes: that way we get the purge batches of 20 pages to set a fresh purge view (limit) more often, and we can reduce the number of old row versions purge has to look at when it decides if it can remove some delete-marked index record
Added MAX_PASSWORD_LENGTH. This increased master-slave passwords to 32 bytes (Bug #766)
Fixed server crash on purge master logs or show master logs when binlog is off. (Bug #733)
Since the mysql interactive client or some other phase in communication cuts > 64 kB strings to very short, restrict the output of SHOW INNODB STATUS to at most 60 kB
