Quoting from the bug report:

The pstack library has been included in MySQL since version
4.0.0. It's useless and should be removed.

Details: According to its own documentation, pstack only works
on Linux on x86 in 32 bit mode and requires LinuxThreads and a
statically linked binary. It doesn't really support any Linux
from 2003 or later and doesn't work on any other OS.

The --enable-pstack option is thus deprecated and has no effect.

GCOV builds were broken after the patch for Bug#57933
which added add -Wdeclaration-after-statement to gcc builds.

This patch fixes:
stacktrace.c:328: warning: ISO C90 forbids mixed
declarations and code

No test case added.

Bug#58041 : Moved rpl_binlog_row to daily. Run just main suite for ps_row and embedded per push. Other suites run daily

sporadically.

The cause of the sporadic time out was a leaking protection
against the global read lock, taken by the RENAME statement,
and not released in case of an error occurred during RENAME.
The leaking protection counter would lead to the value of
protect_against_global_read never dropping to 0.
Consequently FLUSH TABLES in all connections, including the
one that leaked the protection, could not proceed.
 
The fix is to ensure that all branchesin RENAME code properly
release GRL protection.

sql/sql_rename.cc:
  mysql_rename_tables() modified: replaced return from function
  to goto to clean up code block in case of error.

There were actually more problems in this area:
  Slaves (if any) were unconditionally restarted, this appears unnecessary.
  Sort criteria were suboptimal, included the test name.
Added logic to "reserve" a sequence of tests with same config for one thread
Got rid of sort_criteria hash, put it into the test case itself
Adds little sanity check that expected worker picks up test
Fixed some tests that may fail if starting on running server
Some of these fail only if *same* test is repeated.
Finally, special sorting of tests that do --force-restart

first part, for autotools build.

config/ac-macros/maintainer.m4:
  Add the flag. With it, and as we use -Werror, we nicely get
  "error: ISO C90 forbids mixed declarations and code" if
  a declaration follows a statement in C code.
  Note that g++ refuses this flag.

in sql_show.cc, find_files()

Removed the extra allocation.

            by a function and column

The bugreport reveals two different bugs about grouping
on a function:

1) grouping by the TIME_TO_SEC function result caused
   a server crash or wrong results and
2) grouping by the function returning a blob caused
   an unexpected "Duplicate entry" error and wrong
   result.

Details for the 1st bug:

TIME_TO_SEC() returns NULL if its argument is invalid (empty
string for example). Thus its nullability depends not only
on the nullability of its arguments but also on their values.
Fixed by (overoptimistically) setting TIME_TO_SEC() to be
nullable despite the nullability of its arguments.

Details for the 2nd bug:

The server is unable to create indices on blobs without
explicit blob key part length. However, this fact was
ignored for blob function result fields of GROUP BY
intermediate tables.
Fixed by disabling GROUP BY index creation for blob
function result fields like regular blob fields.

On Windows, the parameter for number of bytes passed into WriteFile()
and ReadFile() is DWORD. Casting is needed to silence the warning on
64-bit Windows.

Also, adding several asserts to ensure the variable for number of bytes
is no more than 32 bits, even on 64-bit Windows.

This is for InnoDB Plugin.

Fix handling of update_undo_logs at trx commit. Previously, when
rseg->update_undo_list grows beyond 500 the update_undo_logs were
marked with state TRX_UNDO_TO_FREE which should have been

"Grantor" columns' data is lost when replicating mysql.tables_priv.
Slave SQL thread used its default user ''@'' as the grantor of GRANT|REVOKE
statements executing on it.

In this patch, current user is put in query log event for all GRANT and REVOKE
statement, SQL thread uses the user in query log event as grantor.

  Simplified cases where a select was used to compare variable against ''

Rows events were applied wrongly on the temporary table with the same name.
But rows events are generated only for base tables. As temporary
table's data never be binlogged on row mode. Normally, base table of the
same name cannot be updated if a temporary table has the same name.
But there are two cases which can generate rows events on 
the base table of same name.
      
Case1: 'CREATE TABLE ... SELECT' statement.
In mixed format, it will generate rows events if it is unsafe.
      
Case2: Drop a transactional temporary table in a transaction
       (happens only on 5.5+).
BEGIN;
DROP TEMPORARY TABLE t1;       # t1 is a InnoDB table
INSERT INTO t1 VALUES(rand()); # t1 is a MyISAM table
COMMIT;
'DROP TEMPORARY TABLE' will be put in the transaction cache and
binlogged after the rows events generated by the 'INSERT' statement.
      
After this patch, slave opens only base table when applying a rows event.

Fix assorted warnings that are generated in optimized builds.
Most of it is silencing variables that are set but unused.

This patch also introduces the MY_ASSERT_UNREACHABLE macro
which helps the compiler to deduce that a certain piece of
code is unreachable.

include/my_compiler.h:
  Use GCC's __builtin_unreachable if available. It allows
  GCC to deduce the unreachability of certain code paths,
  thus avoiding warnings that, for example, accused that a
  variable could be used without being initialized (due to
  unreachable code paths).

Fix assorted compiler warnings.

include/my_pthread.h:
  Like for pthread_cond_timedwait, the abstime is constant.
mysys/my_gethwaddr.c:
  Instead of using a manual copy that introduce warnings due to
  type mismatch, copy the buffer using memcpy and use memcmp to
  check whether all bytes of the buffer are zeroed.
mysys/thr_mutex.c:
  Like for pthread_cond_timedwait, the abstime is constant.
unittest/mytap/tap.h:
  Introduce a ok() variant that does not take a format argument.
  Since ok() is tagged with a printf attribute, GCC complains if
  the fmt argument is NULL.

Limited to actual bug fix, fixing a while condition
Again confirmed on Linux PPC and on AIX 5.3

Tag or remove unused arguments and variables.

regex/main.c:
  Use the real prototype.
sql/ha_ndbcluster.cc:
  Make conditions less ambiguous.

Ensure that fdatasync is properly declared as on Mac OS X, the
function is available but there is no prototype. Also, port a
fix for a warning from the InnoDB plugin over to the builtin. 

configure.in:
  Check that fdatasync is declared.
mysys/my_sync.c:
  Use fdatasync only if it is declared.
storage/innobase/include/ut0dbg.h:
  Port over from the plugin a fix for a warning.

Just check for all the functions that we are going to use, not a subset
of them.
