recent, switched back to the older AC_PROG_LIBTOOL

Need to make sure the tmp join doesn't point to the structure already 
freed by the cleanup() for the "base" join, as this can lead to 
double free, because sometimes both tmp_join and join point to the 
same tmp_table_params.copy_field array.

path names than 99 characters, using the USTAR format of the
resulting source TAR.

To be able to specify the use of USTAR when creating the source
TAR, we needed both to update the GNU autotools version requirements
slightly, and update the initiation of the tools to use more
modern constructs.

error in the query.

Fixes a leak after materializing a GROUP BY subquery to a 
temp table when the subquery has a blob column in the SELECT
list.
Fixed by correctly destructing temporary buffers for re-usable
queries

The test case rpl_binlog_corruption fails on windows because when
adding a line to the binary log index file it gets terminated
with a CR+LF (which btw, is the normal case in windows, but not on
Unixes - LF). This causes mismatch between the relay log names,
causing mysqld to report that it cannot find the log file.

We fix this by creating the instrumented index file through
mysql, ie, using SELECT ... INTO DUMPFILE ..., as opposed on
relying on ultimatly OS commands like: -- echo "..." >
index. These changes go into the file and make the procedure
platform independent:

  include/setup_fake_relay_log.inc

Side note: when using SELECT ... INTO DUMPFILE ..., one needs to
check if mysqld is running with secure_file_priv. If it is, we do
it in two steps: 1. create the file on the allowed location;
2. move it to the datadir. If it is not, then we just create the
file directly on the datadir (so previous step 2. is not needed).

resulution of bug #46895.

            REVOKE/GRANT; ALTER EVENT.

The following statements support the CURRENT_USER() where a user is needed.
  DROP USER 
  RENAME USER CURRENT_USER() ...
  GRANT ... TO CURRENT_USER()
  REVOKE ... FROM CURRENT_USER()
  ALTER DEFINER = CURRENT_USER() EVENT
but, When these statements are binlogged, CURRENT_USER() just is binlogged
as 'CURRENT_USER()', it is not expanded to the real user name. When slave 
executes the log event, 'CURRENT_USER()' is expand to the user of slave 
SQL thread, but SQL thread's user name always NULL. This breaks the replication.

After this patch, All above statements are rewritten when they are binlogged.
The CURRENT_USER() is expanded to the real user's name and host.

Updated the certs to expire on 2015. 
Made sure they work with both yassl and openssl.

column is used for ORDER BY

Problem: filesort isn't meant for null length sort data
(e.g. char(0)), that leads to a server crash.

Fix: disregard sort order if sort data record length is 0 (nothing
to sort).

  in multitable delete/subquery

SQL_BUFFER_RESULT should not have an effect on non-SELECT 
statements according to our documentation.
Fixed by not passing it through to multi-table DELETE (similarly
to how it's done for multi-table UPDATE).

merging patches prepared for 5.0 to 5.1-bt. That caused a few changes in the test file

Define env. vars for both timeout settings
Also incorporated 5.0 patch into mtr version 1

--extended-insert

Help message changed to the same as in the 5.1 online 
documentation.

  Define env. vars for both timeout settings
  This patch is for 5.0 (mtr v1) and should replaces for 5.1 up

printstack() being present

When Bug#47391 was fixed, no assumption was made that support
for Solaris 8 was needed. Solaris 8 lacks printstack(), and 
the build breaks because of this.

This patch adds a test for the presence of printstack() to
configure.in for 5.0, and uses HAVE_PRINTSTACK to make
decisions rather than the __sun define.

The 'rpl_get_master_version_and_clock' test verifies if the slave I/O
thread tries to reconnect to master when it tries to get the values of
the UNIX_TIMESTAMP, SERVER_ID from master under network disconnection.
So the master server is restarted for making the transient network
disconnection, during the period the COM_REGISTER_SLAVE failures are
produced in server log file when the slave I/O thread tries to
register on master.

To fix the problem, suppress COM_REGISTER_SLAVE failures in server log
file by mtr suppression, because they are expected.


mysql-test/suite/rpl/r/rpl_get_master_version_and_clock.result:
  Removed mtr.add_suppression("Get master clock failed with error: ")
  and mtr.add_suppression("Get master SERVER_ID failed with error: ").
  Because they are suppressed globally.

MySQL's hash functions MD5 and SHA relied on the somewhat slow 
sprintf function to convert the digests to hex representations.
This patch replaces the sprintf with a specific and inline hex
conversion function.

Patch contributed by Jan Steemann.

sql/item_strfunc.cc:
  Add a hex conversion function.
