More DBUG info for replication
Better error messages from replication
Fixed bug in replication code when connecting to 'localhost' (time was not released properly)
Block ALARM signal on Linux for signal handler thread (Fixes problem with running mysqld with --debug)
Removed warning when setting an AUTO_INCREMENT field to NULL
Fixed bugs in my last changeset that made MySQL hard to compile.
Added mutex around some data that could cause table cache corruptions when using OPTIMIZE TABLE / REPAIR TABLE or automatic repair of MyISAM tables.
Added mutex around some data in the slave start/stop code that could cause THD linked list corruptions
Extended my_chsize() to allow one to specify a filler character.
Extend vio_blocking to return the old state (This made some usage of this function much simpler)
Added testing for some functions that they caller have got the required mutexes before calling the function.
Use setrlimit() to ensure that we can write core file if one specifies --core-file.
Added --slave-compressed-protocol
Made 2 the minimum length for ft_min_word_len
Added variables foreign_key_checks & unique_checks.
Less logging from replication code (if not started with --log-warnings)
Changed that SHOW INNODB STATUS requre the SUPER privilege
More DBUG statements and a lot of new code comments
(All commit emails since 4.0.1 checked)
This had to be done now, before the 4.1 tree changes to much, to make it easy to propagate bug fixes to the 4.1 tree.
DBUG_ macro cleanup
buffer boundary cleanup
This changeset, although not fully tested, works for me better than
anything I've had so far, including what is in the repository. I will
push it unless something crashes while I am writing this :-)
fixed apparent typo in opt_sum.cc
I will push this Changeset although it fails select test - failing select
is better than the code that does not compile.
first pull, merge,test, and get it to work.
The main change is the new replication code - now we have two slave threads
SQL thread and I/O thread. I have also re-written a lot of the code to
prepare for multi-master implementation.
I also documented IO_CACHE quite extensively and to some extend, THD class.
send_file() is more stack-friendly - changed large static buffer to alloc_root()
fixed my_b_seek() to work with WRITE_CACHE
test case to make sure the slave starts correctly after being stopped
truncated words file so the replication tests will take less time
