Bug fix when using --no-deaults
Sets ref_length to right value (faster rnd_pos() handling in InnoDB).
Fixed problem with multi-table-delete and InnoDB
Fixed problem with truncate table, which required a COMMIT before.
Fixed multi-table-delete bug with InnoDB.
Remove not used index from EXPLAIN
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
Faster 'read_first_row' (Fixes slow 'preparing' state)
Read constant tables earlier, which provides better optimzations when using tables with <=1 row.
This also fixes a complicated bug involving const tables.
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.
* multi-table updates
* new paid feature for limiting number of queries per hour for users
* optional syntax for multi-table deletes
* optimization for SQL_CALC_FOUND_ROWS
* a small addition for CREATE .. SELECT that will be of future use
I know that all this will require many additions to documentation,
which I have not done, but I am at Arjen's disposal to help him document
all this.
Changed some sql_alloc() -> thd->alloc()
Removed a lot of compiler warnings on Linux Alpha (64 bit)
Fixed some core dumps on 64 bit systems (wrong type for packet_len)
Fixed race condition when using the binary log and INSERT DELAYED which could cause the binary log to have rows that was not yet written to MyISAM tables.
Use LONG_TIMEOUT (one year) instead of ~0 for long timeouts
Fixed error messages.
Fixed problem with const propagation when comparing columns of different types
Added missing InnoDB variables to SHOW VARIABLES.
Fixed bug when doing WHERE 'column_name=NULL' on an indexed column that had NULL values.
Fixed bug when doing 'LEFT JOIN ... ON (column_name = constant) WHERE column_name = constant'
Speed up column-completion in 'mysql'
Don't use ISAM if HAVE_ISAM is not defined
A lot of fixes for the embedded version. All libraries are now included in libmysqld.a
Changed arguments to convert_dirname() to make it more general.
Renamed files in the 'merge' directory to all use a common prefix.
Don't compile both assembler and C functions on x86
