names to lower case using latin1 instead of utf-8 in sql_acl.cc if lower_case_table_names
was on. Also replaced in other such places system_charset_info with files_charset_info
for consistency.
Fix remaining cases of Bug #3596: fix possible races caused by an obsolete value of thd->query_length in SHOW PROCESSLIST and SHOW INNODB STATUS; this fix depends on the fact that thd->query is always set to NULL before setting it to point to a new query
Introduced a new free blocks list. Free blocks are now re-used before
new blocks are allocated from the pool. There is a new status variable
which can be queried by "show status like key_blocks_unused".
Fixed bugs in group_concat with ORDER BY and DISTINCT (Bugs #2695, #3381 and #3319)
Fixed crash when doing rollback in slave and the io thread catched up with the sql thread
Set locked_in_memory properly
Final version of patch.
Adds support for specifying of DEFAULT NOW() and/or ON UPDATE NOW()
clauses for TIMESTAMP field definition.
Current implementation allows only one such field per table and
uses several unireg types for storing info about this properties of
field. It should be replaced with better implementation when new
.frm format is introduced.
BINARY(N) and VARBIBARY(N)
2. More 4.0 compatibility and more BINARY keyword consistency:
2a. CREATE TABLE a (a CHAR(N) BINARY)
is now synonym for
CREATE TABLE a (a CHAR(N) COLLATE xxxx_bin)
2b. SELECT BINARY x
is still synonin for
SELECT x COLLATE xxxxx_bin.
re-using unused LOCK_active_mi to serialize all administrative
commands related to replication:
START SLAVE, STOP SLAVE, RESET SLAVE, CHANGE MASTER, init_slave()
(replication autostart at server startup), end_slave() (replication
autostop at server shutdown), LOAD DATA FROM MASTER.
This protects us against a handful of deadlocks (like BUG#2921
when two START SLAVE, but when two STOP SLAVE too).
Removing unused variables.
Fixed output from mysqlbinlog when using --skip-comments
Fixed warnings from valgrind
Fixed ref_length when used with HEAP tables
More efficent need_conversion()
Fixed error handling in UPDATE with not updateable tables
Fixed bug in null handling in CAST to signed/unsigned
values for TIMESTAMP columns. The solution is not perfect since
we just silently ignoring default value for first TIMESTAMP
column and properly reflecting this fact in SHOW CREATE TABLE.
We can't give a warning or simply support standard syntax
(niladic functions as legal value for default) for first field
since it is 4.0 tree.
Added support for lower_case_table_names=2, which is to be used on case insensitive file systems.
This tells MySQL to preserve the used case of filenames and database names to make it esier to move files between cases sensitive can case insensitive file systems (like Windows and Linux)
"SHOW TABLE STATUS very slow w/large number of tables"
Replaced old algorithm which were used in my_dir() and stored
all information about directory entries in one chunk of memory
with new one which stores file names and MY_STAT structures in
separate memroot, so now we don't need to copy this data during
reallocation of dir_entry array.
mysql_server_init() now returns error code if something went wrong (Bug #2062)
Don't use my_fopen() when reading symlink information as this may cause problems when a lot of files are opened.
Free thread keys with pthread_key_delete() instead of relying on automatic free. (Bug #2062)
Fixed bug in UNION statement with alias '*'. (Bug #1249)
Fixed a bug in DELETE ... ORDER BY ... LIMIT where the rows where not deleted in the proper order. (Bug #1024).
FOUND_ROWS() could return incorrect number of rows after a query with an impossible WHERE condition.
HOW DATABASES doesn't anymore show .sym files (on windows) that doesn't point to a valid directory. (Bug #1385)
