651e6ffa66 [pb problem]: ha_heap->clone() fails on windows because of mess with
'/' and '\' in path delimiters:
- Fix this by creating new handler with exactly the same path line as
  was passed to ha_create/ha_open.

4282ad92cb Bug #12796: Record lost in HEAP table
Two handler objects were present, one was used for an insert and the other for a select
The state of the statistics was local to the handler object and thus the other handler
object didn't notice the insert.
Fix included:
1) Add a new variable key_stat_version added to whenever statistics was considered in need
of update (previously key_stats_ok= FALSE in those places)
2) Add a new handler variable key_stat_version assigned whenever key_stats_ok= TRUE was set
previously
3) Fix records_in_range to return records if records <= 1
4) Fix records_in_range to add 2 to rec_per_key to ensure we don't specify 0 or 1 when it isn't
and thus invoking incorrect optimisations.
5) Fix unique key handling for HEAP table in records_in_range

47a6320657 Always report row type of 'Fixed' for MEMORY tables. (Bug #3094) 2005-08-05 13:19:48 -07:00
konstantin@mysql.com
14344b658a A fix and a test case for Bug#10760 and complementary cleanups.
The idea of the patch
is that every cursor gets its own lock id for table level locking.
Thus cursors are protected from updates performed within the same 
connection. Additionally a list of transient (must be closed at
commit) cursors is maintained and all transient cursors are closed
when necessary. Lastly, this patch adds support for deadlock
timeouts to TLL locking when using cursors.
+ post-review fixes.

2dcf451b81 Bug#10178 - failure to find a row in heap table by concurrent UPDATEs
Moved the key statistics update to info().
The table is not locked in open(). This made wrong stats possible.

No test case for the test suite.
This happens only with heavy concurrency.
A test script is added to the bug report.

91ff64e107 Added options --auto-increment-increment and --auto-increment-offset.
This allows one to setup a master <-> master replication with non conflicting auto-increment series.
Cleaned up binary log code to make it easyer to add new state variables.
Added simpler 'upper level' logic for artificial events (events that should not cause cleanups on slave).
Simplified binary log handling.
Changed how auto_increment works together with to SET INSERT_ID=# to make it more predictable: Now the inserted rows in a multi-row statement are set independent of the existing rows in the table. (Before only InnoDB did this correctly)

a46d7542c9 This is first cset for WL#1394 "Optimize index merge when all involved index ranges include only values with equal keys"
The main idea is to exploit the fact that key scans for "key=const" return ordered sequences of rowids.

784c9526ec WL#1687 - Optimize UNION DISTINCT ... UNION ALL (again).
HEAP: Copies the key count to a backup variable and sets the key count to zero.
That way, no HEAP function will ever try to touch any index.
Re-enabling is done by copying back the backup variable.
To avoid memory leak at table close, disable deletes all index trees.
Re-enabling must be done with empty indexes and data anyway. Otherwise,
the indexes would need to be repaired, wich HEAP is not capable of.
MyISAM: Only the key_map is cleared and set.
Re-enabling must be done with empty indexes and data. Otherwise, repair needs
to be done which will enable all keys persistently.
The former implementation disabled only non-unique keys and maked this persistent.
The new implementation additionally can disable all keys, but only without
making this persistent. Re-enabling all keys can be done without repair,
if data file and indexes are empty.

ebc3b3afac BTREE-indexes in HEAP tables can now be used to optimize ORDER BY
Don't read character set files if we are using only the default charset. In most cases the user will not anymore get a warning about missing character set files
Compare strings with space extend instead of space strip. Now the following comparisons holds:  "a" == "a " and "a\t" < "a". (Bug #3152).
Note: Because of the above fix, one has to do a REPAIR on any table that has an ascii character < 32 last in a CHAR/VARCHAR/TEXT columns.
