Add a _commented_ workaround for Bug#47350. The full solution is tricky
to get right as explained in the bug report. It is not worth the effort
to extend the deprecated autotools framework to support conflicting
plugins and would be too risky for MySQL 5.1 (GA).

OPTIMIZE TABLE recreates the whole table. That is why the counter gets reset.
Making the next autoinc column persistent is a separate issue from resetting
the value after an OPTIMIZE TABLE. We already have a check for ALTER TABLE
and CREATE INDEX to preserve the value on table recreate. We should be able to
add an additional check for OPTIMIZE TABLE to preserve the next value.

Problem: crash in Item_float constructor on DBUG_ASSERT due
to not null-terminated string parameter.

Fix: making Item_float::Item_float non-null-termintated parameter safe:

Use __builtin_stpcpy only if the system supports stpcpy.
This is necessary as in some cases a call to stpcpy will
be emitted if the built-in can not optimized.

include/m_string.h:
  The expansion of stpcpy (in glibc) causes warnings if the
  return value of strmov is not being used. Since stpcpy is
  a GNU extension and the expansion ends up using a built-in
  provided by GCC, use the compiler provided built-in directly
  when possible. Nonetheless, the C library must have stpcpy
  as a call be emitted if the built-in can not optimized.

thr_local_create(): Initialize local->slot_no to ULINT_UNDEFINED.
thr_local_validate(): Allow local->slot_no to be ULINT_UNDEFINED.

Also delete dict_update_statistics() and rename dict_update_statistics_low()
to dict_update_statistics() because the only thing that distinguished those
two functions was the removed parameter.

thr_local_validate(), i_s_locks_row_validate(): New validate
functions, used in UNIV_DEBUG code for checking the state of internal
memory structures.

The test result differs on windows, since

of unix sockets on windows.

Fixed by replacing that column.

Also requires --big-test from some long running tests
and added a weekly run of all test requiring --big-test.

There was a missed corner case in the partitioning
handler, which caused the next_insert_id to be changed
in the second level handlers (i.e the hander of a partition),
which caused this debug assertion.

The solution was to always ensure that only the partitioning
level generates auto_increment values, since if it was done
within a partition, it may fail to match the partition
function.

mysql-test/suite/parts/inc/partition_auto_increment.inc:
  Added tests

  updated results

  updated results
mysql-test/suite/parts/r/partition_auto_increment_myisam.result:
  updated results
sql/ha_partition.cc:
  In <engine>::write_row the auto_inc value is generated
  through handler::update_auto_increment (which calls <engine>::get_auto_increment() if needed).
  If:
  * INSERT_ID was set to 0
  * it was updated to 0 by 'INSERT ... ON DUPLICATE KEY UPDATE' and changed partitions for the row
  Then it would try to generate a auto_increment value in the
  <engine for a specific partition>::write_row, which will
  trigger the assert.
  
  So the solution is to prevent this by,
  in ha_partition::write_row set auto_inc_field_not_null and
  add MODE_NO_AUTO_VALUE_ON_ZERO
  in ha_partition::update_row (when changing partition) temporary
  set table->next_number_field to NULL which calling the
  partitions ::write_row().

in different default schema.

In strict mode, when data truncation or conversion happens,
THD::killed is set to THD::KILL_BAD_DATA.

This is abuse of KILL mechanism to guarantee that execution
of statement is aborted.

The stored procedures execution, on the other hand,
upon detection that a connection was killed, would
terminate immediately, without trying to restore the caller's
context, in particular, restore the caller's current schema.

The fix is, when terminating a stored procedure execution,
to only bypass cleanup if the entire connection was killed,
not in case of other forms of KILL.

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().

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.

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

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.
