The Ctrl-C handler in mysql closes the console while ReadConsole()
waits for console input.
But the main thread was detecting that ReadConsole() haven't read
anything and was processing as if there're data in the buffer.
Fixed to handle correctly this error condition.
No test case added as the test relies on Ctrl-C sent to the client
from its console.
Dropping an user defined function may cause server crash in
case this function is still in use by another thread.
The problem was that our hash implementation didn't update
hash link list properly when hash_update() was called.
and is not described in the manual
- Adding missing initialization for utf8 collations
- Minor code clean-ups: renaming variables,
moving code into a new separate function.
- Adding test, to check that both ucs2 and utf8 user
defined collations work (ucs2_test_ci and utf8_test_ci)
- Adding Vietnamese collation as a complex user defined
collation example.
Original problem was fixed by Magnus (see BUG25807).
Currently only windows debug build causes assertion failure. This patch assures
that my_tell gets correct file descriptor on any platform by DBUG_ASSERT macro.
Setting a key_cache_block_size which is not a power of 2
could corrupt MyISAM tables.
A couple of computations in the key cache code use bit
operations which do only work if key_cache_block_size
is a power of 2.
Replaced bit operations by arithmetic operations
to make key cache able to handle block sizes that are
not a power of 2.
tables
In case system doesn't have native pread/pwrite calls (e.g. Windows)
and there is CHECK TABLE runs concurrently with another statement that
reads from a table, the table may be reported as crashed.
This is fixed by locking file descriptor when my_seek is executed on
MyISAM index file and emulated pread/pwrite may be executed concurrently.
Affects MyISAM tables on platforms that do not have native
pread/pwrite calls (e.g. Windows).
No deterministic test case for this bug.
This bug occurs when error message length exceeds allowed limit: my_error()
function outputs "%s" sequences instead of long string arguments.
Formats like %-.64s are very common in errmsg.txt files, however my_error()
function simply ignores precision of those formats.
Recognize the --no-defaults, --defaults-file and --defaults-extra-file
options. Treat old --config-file argument as if --defaults-extra-file
had been specified instead.
Plus a few other defaults-related cleanups.
errno
Vasil Dimov (at Oracle) noted that pthread_key_create() does not
set errno, so if it fails then we return the wrong error code.
Instead, capture the return value, which is the real error value,
and instead report that.
bug #27715: mysqld --character-sets-dir buffer overflow
bug ##26851: Mysql Client --pager Buffer Overflow
Using strmov() to copy an argument may cause overflow
if the argument's length is bigger than the buffer:
use strmake instead.
Also, we have to encrease the error message buffer size to fit
the longest message.

losing it's .MYD
When OPTIMIZE TABLE is completed it attempts to rename temporary
file to original name. This step may fail on windows when a file
is opened. As a result data file might be deleted and optimized
copy of file (table_name.MYD) remains.
This situation is handled properly by my_delete_allow_opened, so
use it instead of my_delete when attempting to rename a file on
windows.
No suitable test case for this bug.
