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
Fixed mutex bug in DROP DATABASE
Fixed bug when using auto_increment as second part of a key where first part could include NULL.
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
Added statistics information for alarms (for bug tracking)
Don't store "incomplete" in the xxx.cfg file if we are not using --restart. (Crash-me)
Enlarged STACK_BUF_ALLOC becasue of failed crash-me test
Aded new script mysql_tableinfo to make a system directory.
new file
Client-server protocol 4.1 changes - Server side:
* Enhanced metadata information:
- SHOW [COUNT(*)] ERRORS [LIMIT [offset,] rows]
- SHOW [COUNT(*)] WARNING [LIMIT [offset,] rows]
- SHOW TABLE TYPES
- SHOW PRIVILEGES
- SHOW COLUMN TYPES (Not fully implemented)
* Prepared execution
* Long data handling in pieces
* And other misc changes
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.
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
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.
One more notice:
limiting number of queries per hour for different users has been done
on 4.0.1 , but I can port it to 3.23.*
This will require only certain changes, like number of columns in user
table.
I will also make a test case for it, after it is approved by Monty,
as result file will depend on the error message text.
