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.
myisam/mi_check.c:
Key file descriptor is shared among threads and mixed set of
my_pread/my_pwrite and my_seek calls is possible. This is not
a problem on systems that have native pread/pwrite calls.
In case system doesn't have native pread/pwrite calls (e.g. Windows)
we must ensure that my_pread/my_pwrite are not executed at the same
time with my_seek. This is done by passing MY_THREADSAFE flag to
my_seek.
mysys/my_seek.c:
On platforms that do not have native pread/pwrite calls (e.g. Windows)
these calls are emulated as follow: lock fd, lseek, read, unlock fd.
In case file descriptor is shared among threads, where one thread
executes my_pread and another thread executes my_seek, we may read
from a wrong position. This may happen because my_seek doesn't lock
fd and thus may be executed by another thread after emulated pread
has done lseek and before it has done read.
To fix problem mentioned above we introduce new flag MY_THREADSAFE to
my_seek, which is meaningful only in case pread/pwrite calls are
emulated. If this flag is set, lseek operation is performed as follow:
lock fd, seek, unlock fd.
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.
extra/my_print_defaults.c:
Make help text more accurate regarding how --config-file, --defaults-file, and --defaults-extra-file should be used. Flag --config-file as deprecated.
mysys/default.c:
Always print a newline after listing the default files, even if
--defaults-file= was set (in my_print_default_files()).
scripts/mysqld_multi.sh:
Recognize --no-defaults, --defaults-file and --defaults-extra-file options.
Treat old --config-file argument as if --defaults-extra-file had been specified
instead.
Improve find_groups() method, to honor --defaults-file, etc.
A few random drive-by cleanups, while I'm here.
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.
mysys/my_thr_init.c:
pthread functions don't set the global errno, which should be
obvious.
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.
client/mysql.cc:
Fix for
bug #27715: mysqld --character-sets-dir buffer overflow
bug ##26851: Mysql Client --pager Buffer Overflow
- use strmake() instead of strmov() to avoid buffer overflow.

mysys/charset.c:
Fix for
bug #27715: mysqld --character-sets-dir buffer overflow
bug ##26851: Mysql Client --pager Buffer Overflow
- encrease error message buffer size to fit the (possible) longest message.
Fix for when memory pre-allocation fails.
mysys/my_alloc.c:
Added code to null-out the pre-alloc pointer if allocation fails. This is necessary for the next time this procedure is called.
mysql-test/r/variables-big.result:
Added "big" test for bug fix Bug #27322.

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.
mysys/my_redel.c:
Attempting to delete an opened file and to immediately create
a new one with the same name may result in my_redel failure on
windows. It may fail because file is not deleted until it is
closed.
This situation is handled properly by my_delete_allow_opened, so
use it instead of my_delete.
