and BUG#19208 "Test 'rpl000017' hangs on Windows".
Both bugs are caused by attempting to delete an opened
file and to create immediatedly a new one with the same
name. On Windows it can be supported only on NT-platforms
(by using FILE_SHARE_DELETE mode and with renaming the
file before deletion). Because deleting not-closed files
is not supported on all platforms (e.g. Win 98|ME) this
is to be considered harmful and should be eliminated by
a "code redesign".
VC++Files/mysys/mysys.vcproj:
To be sure that __NT__ is defined for Win configurations.
Temporary, to be changed in more appropriate way.
include/my_sys.h:
Adding my_delete_allow_opened to be invoked to delete
a (possibly) not closed file on Windows NT-platforms.

sql/table.h:
Change the type of db_length to uint from uint32: LEX_STRING uses uint for
length, we need a small and consistent set of types to store length to
minimize cast and compile failures.
Addendum fixes after changing the condition variable
for the global read lock.
The stress test suite revealed some deadlocks. Some were
related to the new condition variable (COND_global_read_lock)
and some were general problems with the global read lock.
It is now necessary to signal COND_global_read_lock whenever
COND_refresh is signalled.
We need to wait for the release of a global read lock if one
is set before every operation that requires a write lock.
But we must not wait if we have locked tables by LOCK TABLES.
After setting a global read lock a thread waits until all
write locks are released.

The problem was a call to convert_dirname() with a destination buffer
that did not have room for the trailing slash added by that function.
This could cause the instance manager to crash in some cases.

Bug#17667: An attacker has the opportunity to bypass query logging.
This adds a new, local-only printf format specifier to our *printf functions
that allows us to print known-size buffers that must not be interpreted as
NUL-terminated "strings."
It uses this format-specifier to print to the log, thus fixing this
problem.
include/my_sys.h:
Add prototype for my_memmem() .
mysys/Makefile.am:
Add reference to new file, my_memmem.c
mysys/mf_iocache2.c:
Add a "%.1234b" and "%.*b" percent-code. It takes a width, just like "%s",
but unlike the string-indicator, it requires the width and doesn't stop printing
at NUL characters.
Also, simplify the code a bit.
TODO: This code should be unified with the strings/my_vnsprintf.c code in
the future.
sql/sql_parse.cc:
The query is not a C-string, but is a sized buffer, containing any character
at all, which may include NUL characters.
strings/my_vsnprintf.c:
Add a "%.1234b" and "%.*b" percent-code. It takes a width, just like "%s",

tests/Makefile.am:
We may need some of our local functions.

Implement memmem, a black-box work-alike of the GNU memmem(), which functions
like strstr() but for arbitrary blocks of memory.
Updating data in HEAP table with BTREE index results in wrong index_length
counter value, which keeps growing after each update.
When inserting new record into tree counter is incremented by:
sizeof(TREE_ELEMENT) + key_size + tree->size_of_element
But when deleting element from tree it doesn't decrement counter by key_size:
sizeof(TREE_ELEMENT) + tree->size_of_element
This fix makes accurate allocated memory counter for tree. That is
decrease counter by key_size when deleting tree element.
heap/hp_delete.c:
Added size of the key to tree_delete() for accurate allocated memory counter.
include/my_tree.h:
Added size of the key to tree_delete() for accurate allocated memory counter.
myisam/myisamlog.c:
Added size of the key to tree_delete() for accurate allocated memory counter.
mysql-test/r/heap_btree.result:
Testcase for BUG#18160.
mysql-test/t/heap_btree.test:
Testcase for BUG#18160.
mysys/tree.c:
Added size of the key to tree_delete() for accurate allocated memory counter.
Note that this size is optional. If one doesn't need precise counter it is safe
to pass 0 as key_size.
The bug caused a reported index corruption in the cases when
key_cache_block_size was not a multiple of myisam_block_size,
e.g. when key_cache_block_size=1536 while myisam_block_size=1024.
mysql-test/r/key_cache.result:
Added a test case for bug #19079.
mysql-test/t/key_cache.test:
Added a test case for bug #19079.
- Improved solution by adding an else stetment so that do find next is avoided if erorr occurs, but we still return zero files found instaed of an error
mysys/my_lib.c:
Add else statment so that if a directory can't be read because of access denied it will be skipped and zero files returned.
Use strnmov instead of strmov to avoid writing after end of buffer
- Grab the path from "configure --sysconfdir=<path>" and set it as
the first place to look for my.cnf files
Do this both in Makefiles for libmysql and mysys
- Patch provided by Francesco Riosa. Thank you!
libmysql/Makefile.shared:
Grab the path from "--sysconfdir=<path>" into the defined variable DEFAULT_SYSYCONFDIR
mysys/Makefile.am:
Grab the path from "--sysconfdir=<path>" into the defined variable DEFAULT_SYSYCONFDIR
mysys/default.c:
Use DEFAULT_SYSCONFDIR as first place to look for my.cnf file if "--sysconfdir=<path>" been specified as argument to configure
- Make the windows implementation of 'my_dir' behave like the default implementation
mysys/my_lib.c:
If 'findfirst' returns EINVAL, just continue and return 0 files to read in this dir.

A wrong cast led to numeric overflow for data files
greater than 4GB. The parallel repair assumed end of
file after reading the amount of data that the file
was bigger than 4GB. It truncated the data file and
noted the number of records it found so far in the
index file header as the number of rows in the table.
Removing the cast fixed the problem.
I added some cosmetic changes too.
The normal repair worked because it uses a different
function to read from the data file.
mysys/mf_iocache.c:
Bug#11527 - Setting myisam_repair_threads to >1 leads to corruption
The pure fix was to remove a cast from a file offset difference.
Supplemented this with warnings in function comments,
a change from == to <= to be slightly more safe,
a renaming from "read_len" to "left_length" to make the
partial code duplication between _my_b_read() and _my_b_read_r()
more obvious and easier to compare the functions,
removed another unnecessary (but harmless) cast,
and fixed coding sytle around the "left_length" changes.
- Set the value of mp->thread before mp->count to avoid race condition.
mysys/thr_mutex.c:
Set mp->thread before mp->count is changed.
Since mp->count is used in the macros 'safe_mutex_assert_not_owner' and
'safe_mutex_assert_owner' as an inidicator wheter to look at the mp->thread
variable or not. This means that when mp->count is changed, the mp->thread
should akready be set to the owning thread.
Also set mp->thread to 0 when unlocking the mutex.

when high concurrency": remove HASH::current_record and make it

The bug was in a race condition in table_hash_search,
