("A pre-requisite patch for the fix for Bug#52044.")

It happens because close_thread_tables() is now called in
open_and_lock_tables upon failure.  Hence, table is no longer
open when optimizer tries to do cleanup.

Fix: Make sure to do cleanup in st_select_lex_unit::prepare()
upon failure. This way, cleanup() is called before tables are
released.

mysql-test/r/subselect.result:
  Added test case for Bug#57704.

  Added test case for Bug#57704.
sql/sql_union.cc:
  st_select_lex_unit::prepare():  On failure, make sure cleanup()
  is called.

ALTER TABLE RENAME, DISABLE KEYS.

The code of ALTER TABLE RENAME, DISABLE KEYS could
issue a commit while holding LOCK_open mutex.
This is a regression introduced by the fix for
Bug 54453.
This failed an assert guarding us against a potential
deadlock with connections trying to execute
FLUSH TABLES WITH READ LOCK.

The fix is to move acquisition of LOCK_open outside
the section that issues ha_autocommit_or_rollback().
LOCK_open is taken to protect against concurrent
operations with .frms and the table definition
cache, and doesn't need to cover the call to commit.

A test case added to innodb_mysql.test.

The patch is to be null-merged to 5.5, which
already has 54453 null-merged to it.

mysql-test/suite/innodb/r/innodb_mysql.result:
  Added test results for test for bug#56619.
mysql-test/suite/innodb/t/innodb_mysql.test:
  Added test for bug#56619.
sql/sql_table.cc:
  mysql_alter_table() modified: moved acquisition of LOCK_open
  after call to ha_autocommit_or_rollback.

sql/item_func.cc:
  Item_func::fix_fields modified: increased minimal required stack
  size in call to check_stack_overrun().

The problem was that the scheduler function used to handle a
new user connection could use the ER() macro without having a
THD object bound to the current thread. The crash would happen
whenever the function failed to create a new thread to handle a
user connection. Thread creation can fail due to lack or limit
of available resources.

The solution is to simply use the ER_THD() macro instead and pass
to it the THD object which would be bound to the connection.

Fix was tested manually. In a test case, it is too cumbersome to
inject a error in this context.

sql/mysqld.cc:
  Use ER_THD and pass the object.

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.

Bug#58041 : Created separate per push and daily collections for 5.5-bugteam. Moved rpl_binlog_row to daily. Run just main suite for ps_row and
embedded per push. Other suites run daily

storage/ndb/src/mgmsrv/InitConfigFileParser.cpp:
  Added 'const' to fix compilation error.

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.

mysql-test/r/log_tables.result:
  Added results for test for bug#47924.
mysql-test/t/log_tables.test:
  Added test for bug#47924.
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

from 5.1; extended here to Cmake builds.

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.

add boolean command-line option --autocommit.

mysql-test/mysql-test-run.pl:
  do in --gdb like in --ddd: to let the developer debug the startup
  phase (like command-line options parsing), don't "run".
  It's the third time I do this change, it was previously lost
