storage engine returns errno 12
If there is not enough memory to store or update blob record
(while allocating record buffer), myisam marks table as crashed.
With this fix myisam attempts to roll an index back and return
an error, not marking a table as crashed.
Affects myisam tables with blobs only. No test case for this fix.
Problem described in this bug report affects MyISAM tables only.
Running mysqld --flush instructs mysqld to sync all changes to disk
after each SQL statement. It worked well for INSERT and DELETE
statements, but it did sync for UPDATE only in case if there was
index change (change of colum that has an index). If no updated column
has an index, data wasn't synced to disk.
This fix makes UPDATE statement to sync data to disk even if there is
no index change (that is only data change) and mysqld is run with
--flush option.
CHECK TABLE did temporarily clear the auto_increment value.
It runs with a read lock, allowing other readers and
conurrent INSERTs. The latter could grab the wrong value
in this moment.
CHECK TABLE does no longer modify the auto_increment value.
Not even for a short moment.
For "count(*) while index_column = value" an index read
is done. It consists of an index scan and retrieval of
each key.
For efficiency reasons the index scan stores the key in
the special buffer 'lastkey2' once only. At the first
iteration it notes this fact with the flag
HA_STATE_RNEXT_SAME in 'info->update'.
For efficiency reasons, the key retrieval for blobs
does not allocate a new buffer, but uses 'lastkey2'...
Now I clear the HA_STATE_RNEXT_SAME flag whenever the
buffer has been polluted. In this case, the index scan
copies the key value again (and sets the flag again).
This patch allows to configure MyISAM for 128 indexes per table.
The main problem is the key_map, wich is implemented as an ulonglong.
To get rid of the limit and keep the efficient and flexible
implementation, the highest bit is now used for all upper keys.
This means that the lower keys can be disabled and enabled
individually as usual and the high keys can only be disabled and
enabled as a block. That way the existing test suite is still
applicable, while more keys work, though slightly less efficient.
To really get more than 64 keys, some defines need to be changed.
Another patch will address this.
Changed my_error() to print error messages, which come from
arbitrary registered ranges of error messages. Messages can
be unregistered (and should be at end of the program).
Added registration of handler error messages.
Added a new mi_print_error() macro and a new
mi_report_error() function, which supply error
messages with a table name.
Added calls to mi_print_error() or mi_report_error()
at all places in MyISAM, where table corruption is detected.
Some simple optimzations, more comments and indentation changes.
Add ` around database in 'use database' in binary log.
Moved max_error_count and max_warning_count to variables struct.
Removed SHOW_WARNS_COUNT and SHOW_ERRORS_COUNT calls.
Changed string functions to use character set of first string argument as default return characterset
(Each string function can change the above assumption if needed)
Fixed configure problems with HPUX and openbsd
SHOW SLAVE STATUS returns empty set if slave is not initialized
SHOW MASTER STATUS returns empty set if binary logging is not enabled.
Fixed shutdown problem on Solaris.
