"temporary table with data directory option fails"
myisam should not use user-specified table name when creating
temporary tables and use generated connection specific real name.
Test included.
Very complex select statements can create temporary tables
that are too big to be represented as a MyISAM table.
This was not checked at table creation time, but only at
open time. The result was an attempt to delete the
"impossible" table.
But if the server is built --with-raid, MyISAM tries to
open the table before deleting the files. It needs to find
out if the table uses the raid support and how many raid
chunks there are. This is done with an open "for repair",
which will almost always succeed.
But in this case we have an "impossible" table. The open
failed. Hence the files were not deleted. Also the error
message was a bit unspecific.
I turned an open error in this situation into the assumption
of having no raid support on the table. Thus the normal data
file is tried to be deleted. This may however leave existing
raid chunks behind.
I also added a check in mi_create() to prevent the creation
of an "impossible" table. A more decriptive error message is
given in this case.
No test case. The required select statement is way too
large for the test suite. I added a test script to the
bug report.
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 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
Fixes for embedded server
Made key_cache more configurable
Fixed that one can change key blocksize in MyISAM
A lot of optimizations to make MyISAM slightly faster
Fixed error number handling bug in mysqltest.
Fixed that error number from insert delayed is reported correctly.
merged new vio code with old violite code.
Added preliminary handling of symlinks in MyISAM.
When using myisamchk to check tables with --force, don't repair
tables that are marked as 'not closed' if they are ok.
Change fn_format() to use my_real_path and my_symlink
