The problem is that MySQL's 'fast' mutex implementation uses the
random() routine to determine the spin delay. Unfortunately, the
routine interface is not thead-safe and some implementations (eg:
glibc) might use a internal lock to protect the RNG state, causing
excessive locking contention if lots of threads are spinning on
a MySQL's 'fast' mutex. The code was also misusing the value
of the RAND_MAX macro, this macro represents the largest value
that can be returned from the rand() function, not random().
The solution is to use the quite simple Park-Miller random number
generator. The initial seed is set to 1 because the previously used
generator wasn't being seeded -- the initial seed is 1 if srandom()
is not called.
Futhermore, the 'fast' mutex implementation has several shortcomings
and provides no measurable performance benefit. Therefore, its use is
not recommended unless it provides directly measurable results.
include/my_pthread.h:
Add field to keep the RNG state.
mysys/thr_mutex.c:
Use a palliative per-mutex rng state to determine the spin delay.
The RNG is not thread-safe but jumping a few sequences in the RNG
is harmless.
This patch contains fixes for two problems:
1. As originally reported, the server crashed on Mac OS X when trying to access
an EXAMPLE table after the EXAMPLE plugin was installed.
It turned out that the dynamically loaded EXAMPLE plugin called the
function hash_earch() from a Mac OS X system library, instead of
hash_earch() from MySQL's mysys library. Makefile.am in storage/example
does not include libmysys. So the Mac OS X linker arranged the hash_search()
function to be linked to the system library when the shared object is
loaded.
One possible solution would be to include libmysys into the linkage of
dynamic plugins. But then we must have a libmysys.so, which must be
used by the server too. This could have a minimal performance impact,
but foremost the change seems to bee too risky at the current state of
MySQL 5.1.
The selected solution is to rename MySQL's hash_search() to my_hash_search()
like it has been done before with hash_insert() and hash_reset().
Since this is the third time, we need to rename a hash_*() function,
I did renamed all hash_*() functions to my_hash_*().
To avoid changing a zillion calls to these functions, and announcing
this to hundreds of developers, I added defines that map the old names
to the new names.
This change is in hash.h and hash.c.
2. The other problem was improper implementation of the handlerton-to-plugin
mapping. We use a fixed-size array to hold a plugin reference for each
handlerton. On every install of a handler plugin, we allocated a new slot
of the array. On uninstall we did not free it. After some uninstall/install
cycles the array overflowed. We did not check for overflow.
One fix is to check for overflow to stop the crashes.
Another fix is to free the array slot at uninstall and search for a free slot
at plugin install.
This change is in handler.cc.
include/hash.h:
Bug#37958 - test main.plugin crash on Mac OS X when selecting from EXAMPLE engine.
Renamed hash_*() functions to my_hash_*().
Added defines that map old names to new names.
mysys/hash.c:
Bug#37958 - test main.plugin crash on Mac OS X when selecting from EXAMPLE engine.
Renamed hash_*() functions to my_hash_*().
sql/handler.cc:
Bug#37958 - test main.plugin crash on Mac OS X when selecting from EXAMPLE engine.
Protect against a failing ha_initialize_handlerton() in ha_finalize_handlerton().
Free hton2plugin slot on uninstall of a handler plugin.
Reuse freed slost of the hton2plugin array.
Protect against array overrun.
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.
test_if_data_home_dir fixed to look into real path.
Checks added to mi_open for symlinks into data home directory.

mysys/safemalloc.c:
Make the various print-functions happy:
sf_malloc_(cur|max)_memory are size_t now, might as well use %u instead
of %d. Ideally, we'd use %zu, but we can't rely on having that, so we'll
use %lu instead. Likewise, we could cast to unsigned for our poor man's
%p -- pointers are never negative, and neither is %x --, but since it
was fixed to %p with seemingly no ill effects in 6.0 anyway, we'll back
port that instead.
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.
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.
Another problem is that the backtrace facility wasn't being
enabled for non-Linux targets even if the target OS has the
backtrace functions. Also, the stacktrace functions inside
mysqltest were being used without proper checks for their
presence in the build.
client/mysqltest.c:
Only use stacktrace functions if they are available.
configure.in:
Check if the compiler defines __bss_start
include/my_stacktrace.h:
Enable stacktrace if system has backtrace functions.
mysys/stacktrace.c:
Use backtrace functions if the system supports it.
sql/mysqld.cc:
Only use stacktrace functions if they are available.
The problem was that when a embedded linked version of mysqltest
crashed there was no way to obtain a stack trace if no core file
is available. Another problem is that the embedded version of
libmysql was not behaving (crash) the same as the non-embedded with
respect to sending commands to a explicitly closed connection.
The solution is to generate a mysqltest's stack trace on crash
and to enable "reconnect" if the connection handle was explicitly
closed so the behavior matches the non-embedded one.
client/CMakeLists.txt:
Link mysys to mysqltest.
client/Makefile.am:
Link mysys to mysqltest.
client/mysqltest.c:
Add fatal signal handling with backtracing for Unix and Windows.
configure.in:
Add check for weak symbols support and remove a spurious word.
include/Makefile.am:
Add new header with prototype for stack tracing functions.
include/my_stacktrace.h:
Add new header with prototype for stack tracing functions.
libmysqld/CMakeLists.txt:
stack tracing is now part of mysys.
libmysqld/Makefile.am:

libmysqld/lib_sql.cc:
Re-connect if connection was explicitly closed. This is
done to match the behavior of the non-embeded libmysql.
mysql-test/t/sql_low_priority_updates_func.test:
Test expects parallelism between queries that cannot be
guaranteed under embedded.
mysys/CMakeLists.txt:
Add stacktrace to mysys.
mysys/Makefile.am:
Add stacktrace to mysys.
mysys/stacktrace.c:
Move stacktrace to mysys and add weak symbol for the
C++ name de-mangling function so that it can later be
overridden in C++ code. Also add my_ prefix to exported
functions.
sql/CMakeLists.txt:
stacktrace was moved to mysys.
sql/Makefile.am:
stacktrace was moved to mysys.
sql/mysqld.cc:
Add my_ prefix to mysys functions.

Each time the server reloads privileges containing table grants, the
system will allocate too much memory than needed because of badly
chosen growth prediction in the underlying dynamic arrays.
This patch introduces a new signature to the hash container initializer
which enables a much more pessimistic approach in favour for more
efficient memory useage.
This patch was supplied by Google Inc.
include/hash.h:
* New signature for _hash_init.
* Defined new function hash_init2 which takes growth_size argument.
mysys/hash.c:
* New signature for _hash_init.
sql/sql_acl.cc:
* Changed hash_init signature so that it takes a 'growth_size' smaller
than the default. Each time a GRANT_TABLE is allocated a pre-allocated
dynamic array is instantiated. A large growth size can result in too
many unused hash-entries per table-entry and thus be a waste of free
memory.

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.

Bug#34678 @@debug variable's incremental mode
The problem is that the per-thread debugging settings stack wasn't
being deallocated before the thread termination, leaking the stack
memory. The chosen solution is to push a new state if the current
is set to the initial settings and pop it (free) once the thread
finishes.
dbug/dbug.c:
Move dbug parser out of _db_set_ to a separate function and
make _db_set_ push a new stack if the corrent one is set to
the initial settings.

The problem is that the Table_locks_waited was incremented only
when the lock request succeed. If a thread waiting for the lock
gets killed or the lock request is aborted, the variable would
not be incremented, leading to inaccurate values in the variable.
The solution is to increment the Table_locks_waited whenever the
lock request is queued. This reflects better the intended behavior
of the variable -- show how many times a lock was waited.
mysql-test/r/lock_multi.result:
Add test case result for Bug#30331
mysql-test/t/lock_multi.test:
Add test case for Bug#30331
mysys/thr_lock.c:
Increment locks_waited whenever the thread is supposed
to wait for the lock.
Fixed that return value of malloc was not checked.
Fixed wrong argument count (compilation failure) to base64_decode()
function.
Note:
- there is no test case for this fix as this code is never compiled
into mysql clients/server;
- as this code is used for internal testing purposes only, no changelog
entry needed.
mysys/base64.c:
Fixed that return value of malloc was not checked.
Fixed wrong argument count to base64_decode function.
- Fix 'my_win_init' code that handles initialization of
"query_performance_counter" and conversion from registry values to
environment strings
mysys/my_init.c:
- Change check of return value from 'QueryPerformanceFrequency', it
returns 0 on error
- Don't return from 'my_win_init' if the registry
key "HKEY_LOCAL_MACHINE\SOFTWARE\MySQL" doesn't exist. This caused
the initialization of "query_performance_counter" to be bypassed unless there
was at lest such a key.
- Cleanup the "registry -> environment variables" from Italian comments,
remove redundant variables and fix style.
- Remove function 'setEnvString' and replace it with oneliner 'strxmov'

Default values of variables were not subject to upper/lower bounds
and step, while setting variables was. Bounds and step are also
applied to defaults now; defaults are corrected quietly, values
given by the user are corrected, and a correction-warning is thrown
as needed. Lastly, very large values could wrap around, starting
from 0 again. They are bounded at the maximum value for the
respective data-type now if no lower maximum is specified in the
variable's definition.
client/mysql.cc:
correct maxima in options array
client/mysqltest.c:
adjust minimum for "sleep" option so default value is no longer
out of bounds.
include/m_string.h:
ullstr() - the unsigned brother of llstr()
include/my_getopt.h:
Flag if we bounded the value (that is, correct anything aside from
making value a multiple of block-size)

mysql-test/r/variables.result:
correct results: bounds and step apply to variables' default values, too
mysql-test/t/variables.test:
correct results: bounds and step apply to variables' default values, too
mysys/my_getopt.c:
- apply bounds/step to default values of variables (based on work by serg)
- print complaints about incorrect values for variables (truncation etc.,
by requestion of consulting)
- if no lower maximum is specified in variable definition, bound unsigned
values at their maximum to prevent wrap-around
- some calls to error_reporter had a \n, some didn't. remove \n from calls,
let reporter-function handle it, so the default reporter behaves like that
in mysqld
sql/mysql_priv.h:
correct RANGE_ALLOC_BLOCK_SIZE (cleared with monty)
sql/mysqld.cc:
correct maxima to correct data-type.
correct minima where higher than default.
correct range-alloc-block-size.
correct inno variables so GET_* corresponds to actual variable's type.
sql/set_var.cc:
When the new value for a variable is out of bounds, we'll send the
client a warning (but not if the value was simply not a multiple of
'blocksize'). sys_var_thd_ulong had this, sys_var_long_ptr_global
didn't; broken out and streamlined to avoid duplication of code.
