           (variables_debug fails)

The problem was that "SET GLOBAL debug" could cause a crash on Solaris.
The crash happened if the server failed to open the trace file given in 
the "SET GLOBAL debug" statement. This caused an error message to be
printed to stderr containing the process name. However, printing to
stderr crashed the server since the pointer to the process name had
not been initialized.

This patch fixes the problem by initializing the process name 
properly when doing "SET GLOBAL debug".

No test case added as this bug was repeatable with existing test
coverage in variables_debug.test.

  Enable the maintainer mode if debug support is enabled.

          replication aborts

When recieving a 'SLAVE STOP' command, slave SQL thread will roll back the
transaction and stop immidiately if there is only transactional table updated,
even through 'CREATE|DROP TEMPOARY TABLE' statement are in it. But These
statements can never be rolled back. Because the temporary tables to the user
session mapping remain until 'RESET SLAVE', Therefore it will abort SQL thread
with an error that the table already exists or doesn't exist, when it restarts
and executes the whole transaction again.

After this patch, SQL thread always waits till the transaction ends and then stops,
if 'CREATE|DROP TEMPOARY TABLE' statement are in it.

The thing is that the following attributes are fixed (remembered) when a trigger
is created:
  - character_set_client
  - character_set_results
  - collation_connection

There are two triggers created in mysql-test/include/mtr_warnings.sql.
They were created using "current default" character set / collation.
is_triggers.test shows definition of these triggers including recorded
character set information.

The problem was that if "current default" changed, the recorded character
set information was not accurate.

There might be two ways to fix that:
  a) update is_triggers.test so that it does not put character-set information
     into result-file;
  b) update mtr_warnings.sql so that the triggers are created using
     hard-coded character sets.

This patch implements option b).

Don't rollback statement transactions if we are in a sub-statement.
This could for example happen for open_ltable() when opening the
general log during execution of a stored procedure.

The root of the problem is that to interrupt a slave SQL thread
wait, the STOP SLAVE implementation uses thd->awake(THD::NOT_KILLED).
This appears as a spurious wakeup (e.g. from a sleep on a
condition variable) to the code that the slave SQL thread is
executing at the time of the STOP. If the code is not written
to be spurious-wakeup safe, unexpected behavior can occur. For
the reported case, this problem led to an infinite loop around
the interruptible_wait() function in item_func.cc (SLEEP()
function implementation).  The loop was not being properly
restarted and, consequently, would not come to an end. Since the
SLEEP function sleeps on a timed event in order to be killable
and to perform periodic checks until the requested time has
elapsed, the spurious wake up was causing the requested sleep
time to be reset every two seconds.

The solution is to calculate the requested absolute time only
once and to ensure that the thread only sleeps until this
time is elapsed. In case of a spurious wake up, the sleep is
restarted using the previously calculated absolute time. This
restores the behavior present in previous releases. If a slave
thread is executing a SLEEP function, a STOP SLAVE statement
will wait until the time requested in the sleep function
has elapsed.

OPTIMIZE TABLE is not directly supported by InnoDB. Instead,
recreate and analyze of the table is done. After recreate,
the table is closed and locks are released before the table
is reopened and locks re-acquired for the analyze phase.

This assertion was triggered if OPTIMIZE TABLE failed to
acquire thr_lock locks before starting the analyze phase.
The assertion tests (among other things) that there no
active statement transaction. However, as part of acquiring
the thr_lock lock, external_lock() is called for InnoDB
tables and this causes a statement transaction to be started.
If thr_multi_lock() later fails (e.g. due to timeout),
the failure handling code causes this assert to be triggered.

This patch fixes the problem by doing rollback of the
current statement transaction in case open_ltable (used by
OPTIMIZE TABLE) fails to acquire thr_lock locks.

Test case added to lock_sync.test.

This patch fixes races in the test which were causing these

for --init-rpl-role.

Problem: There are two variables involved in this issue,
rpl_status and rpl_role_type. The former is an array containing
the description of the possible values for the latter.

rpl_status is declared as an enumeration and is stored in a 4
bytes integer. On the other hand, my_getopt, reads enum values
into a ulong:

  *(ulong*)value= arg;

This is overwriting the memory used for rpl_role_type, 
corrupting the first entry in the array.

Fix: We fix this by re-declaring rpl_status as a ulong, so that it
has space to accommodate the value "parsed" in my_getopt .
