Fixed bug in ALTER TABLE with BDB tables
Updated mysql-test for valgrind
Warning handling and initial prepared statement handling (last not complete yet)
Changed a lot of functions that returned 0/1 to my_bool type.
GRANT handling now uses read/write locks instead of mutex
Change basic net functions to use THD instead of NET
(needed for 4.1 protocol)
Use my_sprintf instead of sprintf() + strlen()
Added alloc_query() to be able to chare query initialization code with
prepared statements.
Cleanup handling of SHOW COUNT(*) WARNINGS and SELECT LAST_INSERT_ID()
Note that the following test fails (will be fixed ASAP):
sub_select, union, rpl_rotate_logs and rpl_mystery22
Improve mysql-test to be more robust.
Fix that GRANT doesn't delete SSL options
Change innobase_flush_log_at_trx_commit to uint.
Don't rotate logs if we read a rotate log entry from the master.
Fixed that GRANT ... REQUIRE options are not forgot when doing new GRANT
Changed fn_ext to point at first '.' after directory.
FLUSH LOGS removed numerical extension for all future update logs.
Fixed the mysqld --help reports right values for --datadir and --bind-address
--log-binary=a.b.c now properly strips of .b.c
Fix that one can DROP UDF functions that was not loaded at startup

Moved max_error_count and max_warning_count to variables struct.
Removed SHOW_WARNS_COUNT and SHOW_ERRORS_COUNT calls.

SHOW SLAVE STATUS returns empty set if slave is not initialized

Fixed shutdown problem on Solaris.
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
Made a some new buffers thread specific and changeable.
Resize of key_buffer.
AUTO_COMMIT -> AUTOCOMMIT

Split handler->extra() to extra() and extra_opt() to be able to support thread specific buffers.
Don't write message to error log when slave reconnects becasue of timeout.
Fixed possible update problem when using DELETE/UPDATE on small tables
(In some cases we used index even if table scanning would be better)
A lot of minior code cleanups
Suppress prints by slave.cc when there is a normal reconnect after the master has been quiet for the time of the net read timeout; this removes the Error 1159 messages many users have complained about in the replication of 3.23.51
SHOW DATABASES
CREATE TEMPORARY TABLE
LOCK TABLES
REPLICATION SLAVE & REPLICATION CLIENT
SUPER
EXECUTE
All scripts & documentation is updated for this change.
Added better error messages for global privileges
(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 :-)
of one of our users which replicates from a live server. So I now have a
lot of confidence in it and will push. It passes all tests, so I if I broke
somebody's code in 3.23 merge this is your fault - you should have had a good test
case :-)
got LOAD DATA INFILE replication from 3.23 master to 4.0 slave to work
for some reason query_cache now fails - will push anyway and document the
failure if I can repeat it.
fixed bug in LOAD DATA FROM MASTER
fixed rpl000001.result
Slave now replicates 3.23 master, with the exception of LOAD DATA INFILE,
which is still buggy. Will push this one after the pull/merge
Test of unsigned BIGINT values
Fixes for queries-per-hour
Cleanup of replication code (comments and portability fixes)
Make most of the binary log code 4G clean
Changed syntax for GRANT ... QUERIES PER HOUR
fixed a couple of bugs with SEQ_READ_APPEND cache
rpl000016 still has non-deterministic result, but I am going to commit and
push since what I have is now better than what is in the main repository
fixed too quick timeout in mysql-test-run which caused a race with the
new server getting started before the old one completely finished
shutdown. This should fix the pid warning we've been getting as well as
inconsistent results when running tests with the manager
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.
added extra/mysql_install.c - will work on it in 4.0, but it does not hurt
to have it sit in 3.23 tree for now since it will eventually be backported
to 3.23 anyway
Stop event and bugs the test suite could not catch
Did some big restructuring of binlog event classes - most important
change is that now each event class has exec_event method and one does
not need to modify slave core code to add a new event. Slave code is
now much smaller and easier to read
fixed test case to produce same results on txn-enabled binary.
temporary fix - permanent fix is it make mysqld behave the same with
MyISAM on auto_increment insert after delete from tbl_name regardless
of how the binary was compiled
sql/slave.cc
fixed concurrency bug with log_seq
sql/slave.h
last_log_seq needs to be updated atomically with pos

fixed bug in handling STOP immediately after ROTATE
added test case for buffer overrun on DROP DATABASE by non-root user
added test case for the STOP bug in replication

added offset argument to sync_with_master to mysqltest to be able to fix sync bugs
added a test case for slave startup with existing master.info
expanded mysql-test-run.sh to be able to run pre-start shell script initializations
slave will skip the first SQL_SLAVE_SKIP_COUNTER events on start -
this is needed to recover from broken replication when the next log
event(s) should just be skipped.
Rotate binlogs when max_binlog_size is reached
fixed bug that created empty result files in no-record mode
mysql-test/t/rpl000007.test

added abort-slave-event-count option to mysqld to test the above
added a test case for temp tables with a contantly aborting slave
removed warning in sql_parse.cc
fixed thimble.cc to compile
while slave thread has temp tables - not hard to fix though, but it is time to go to bed
added a new test case for temp table replication and Slave_open_temp_tables
status variable.
Misc fixes
send_file() is more stack-friendly - changed large static buffer to alloc_root()

test case to make sure the slave starts correctly after being stopped
truncated words file so the replication tests will take less time
