Fix - removed obsolvete setlocale from my_init.c . In MBCS
environments it caused unwanted character-to-byte translations
in fputc() in client code and wrong output as result.
Dumping information about locks in use by sending a SIGHUP signal
to the server or by invoking the "mysqladmin debug" command may
lead to a server crash in debug builds or to undefined behavior in
production builds.
The problem was that a mutex that protects a lock object (THR_LOCK)
might have been destroyed before the lock object was actually removed
from the list of locks in use, causing a race condition with other
threads iterating over the list. The solution is to destroy the mutex
only after removing lock object from the list.
mysys/thr_lock.c:
Destroy the mutex that protects the lock object only after removing
the lock object from the list of locks in use.

Tilde expansion could fail when it was to expand to an empty string (such as
when HOME is set to an empty string), especially on systems where size_t is
unsigned.
This fix is for 5.0 only : back porting the 6.0 patch manually
The parser code in sql/sql_yacc.yy needs to be more robust to out of
memory conditions, so that when parsing a query fails due to OOM,
the thread gracefully returns an error.
Before this fix, a new/alloc returning NULL could:
- cause a crash, if dereferencing the NULL pointer,
- produce a corrupted parsed tree, containing NULL nodes,
- alter the semantic of a query, by silently dropping token values or nodes
With this fix:
- C++ constructors are *not* executed with a NULL "this" pointer
when operator new fails.
This is achieved by declaring "operator new" with a "throw ()" clause,
so that a failed new gracefully returns NULL on OOM conditions.
- calls to new/alloc are tested for a NULL result,
- The thread diagnostic area is set to an error status when OOM occurs.
This ensures that a request failing in the server properly returns an
ER_OUT_OF_RESOURCES error to the client.
- OOM conditions cause the parser to stop immediately (MYSQL_YYABORT).
This prevents causing further crashes when using a partially built parsed
tree in further rules in the parser.
No test scripts are provided, since automating OOM failures is not
instrumented in the server.
Tested under the debugger, to verify that an error in alloc_root cause the
thread to returns gracefully all the way to the client application, with
an ER_OUT_OF_RESOURCES error.
Pull out some of unpack_dirname() into normalize_dirname(); this
new function does not expand "~" to the home directory. Use this
function in unpack_dirname(), and use it during init_default_directories()
to remove duplicate entries without losing track of which directory
is a user's home dir.
Normalize directory names before adding them to default_directories.
mysys/default.c:
Normalize directory names with unpack_dirname() before adding them
to default_directories. This way, /etc/ and /etc will not count as
duplicates.
Because this entails allocating memory to store the normalized names,
add error handling and ensure that it doesn't leak memory in case
both my_print_defaults() and load_defaults() are called.
Clean up the Windows code that finds the exe's parent directory, and
pull it out into a separate function.
Reorganize the code into a single init_default_directories() function,
with internal #ifdefs, instead of init_default_directories_<system>()
functions which were accessed via a function pointer. This is more in
line with normal MySQL coding style, and easier to read for some.
We could allocate chunks larger than 4GB, but did our size-accounting in 32-bit
values. This could lead to spurious warnings, inaccurate accounting, and, in
theory, data loss.
Affected: 64-bit platforms. Debug-build (with safemalloc). At least one buffer
larger than 4GB. For potential data loss, a re-alloc on such a buffer would be
necessary.
mysys/my_static.c:
Make memory-accounting 64-bit safe.
mysys/my_static.h:
Make memory-accounting 64-bit safe.
Move in struct for better alignment when 64-bit.
with errno 17
my_create() did not perform any checks for the case when a file is
successfully created by a call to open(), but the call to
my_register_filename() later fails because the number of open files
has exceeded the my_open_files limit. This can happen on platforms
which do not have getrlimit(), and hence we do not know the real limit
for open files. In such a case an error was returned to a caller
although the file has actually been created. Since callers assume
my_create() to return an error only when it failed to create a file,
they did not perform any cleanups, leaving an 'orphaned' file on the
file system.
Fixed by adding a check for the above case to my_create() and ensuring
the newly created file is deleted before returning an error.
Creating a deterministic test case in the test suite is impossible,
because the exact steps required to reproduce the above situation
depend on the platform and/or environment (OS per-user limits, queries
executed by previous tests, startup parameters). The patch was
manually tested on Windows using examples posted in the bug report.
mysys/my_create.c:
Ensure that, if the call to my_register_filename() in my_create()
failed, but the previous open() called succeeded, the newly created
file is deleted before returning an error.

A user could not override system-wide settings in their ~/.my.cnf,
because the DEFAULT_SYSCONFDIR was being searched last. Also, in
some configurations (especially when the --sysconfdir compile-time
option is set to /etc or /etc/mysql), the system-wide my.cnf file
was read multiple times, causing confusion and potential problems.
Rearrange default directories to conform to the manual and logic.
Move --sysconfdir=<path> (DEFAULT_SYSCONFDIR) from the last default
directory to the middle of the list. $HOME/.my.cnf should be last,
so the user is able to override the system-wide settings.
Change init_default_directories() to remove duplicates from the
list.

mysys/Makefile.am:

mysys/default.c:
Change order in which defaults files are added to default_directories,
in order to conform to the manual (and to common sense). This fixes
a particularly bad problem on Unix, where ~/.my.cnf was read before
/usr/local/etc/my.cnf.
Also, don't add duplicate entries; move the existing entry to the
end of the list instead.
Here is a comparison of the order of defaults files, BEFORE and AFTER
this patch.
On Windows:
BEFORE: C:\, GetWindowsDirectory(), GetSystemWindowsDirectory(),
$MYSQL_HOME, defaults-extra-file, INSTALLDIR
AFTER: GetSystemWindowsDirectory(), GetWindowsDirectory(), C:\,
INSTALLDIR, $MYSQL_HOME, defaults-extra-file
GetSystemWindowsDirectory() is moved before GetWindowsDirectory() because
the former is shared by all Terminal Services users, while the latter is
private for each user.
On Netware (no change):
BEFORE: sys:/etc/, $MYSQL_HOME, defaults-extra-file
AFTER: sys:/etc, $MYSQL_HOME, defaults-extra-file
On OS/2:
BEFORE: $ETC, /etc, $MYSQL_HOME, defaults-extra-file
AFTER: /etc, $ETC, $MYSQL_HOME, defaults-extra-file
On everything else (general Unix):
BEFORE: /etc, $MYSQL_HOME, defaults-extra-file, ~/, --sysconfdir
AFTER: /etc/, --sysconfdir, $MYSQL_HOME, defaults-extra-file, ~/
The BEFORE code added --sysconfdir on all systems, but only the
Unix build system actually defined a value for it.

Since the behavior of write(fd, buf, 0) is undefined, it may fail with
EFAULT on some architectures when buf == NULL. The error was propagated
up to a caller, since my_write() code did not handle it properly.
Fixed by checking the 'number of bytes' argument in my_write() and
returning before calling the write() system call when there is nothing
to write.
mysys/my_write.c:
Return from my_write() before calling the write() system call when the
number of bytes to be written is 0, since the behavior of write() in
this case is not portable.

CPUs / Intel's ICC compile
The bug is a combination of two problems:
1. IA64/ICC MySQL binaries use glibc's qsort(), not the one in mysys.
2. The order relation implemented by join_tab_cmp() is not transitive,
i.e. it is possible to choose such a, b and c that (a < b) && (b < c)
but (c < a). This implies that result of a sort using the relation
implemented by join_tab_cmp() depends on the order in which
elements are compared, i.e. the result is implementation-specific. Since
choose_plan() uses qsort() to pre-sort the
join tables using join_tab_cmp() as a compare function, the results of
the sorting may vary depending on qsort() implementation.
It is neither possible nor important to implement a better ordering
algorithm in join_tab_cmp(). Therefore the only way to fix it is to
force our own qsort() to be used by renaming it to my_qsort(), so we don't depend
on linker to decide that.
This patch also "fixes" bug #20530: qsort redefinition violates the
standard.
include/my_sys.h:
Renamed qsort() and qsort2() to my_qsort() and my_qsort2(). Since
previously we relied on stdlib.h to provide a declaration for qsort(), a
separate declaration for my_qsort() is now required.
