A closely related problem, hardly worth a new bug report:
Removed a spurious call to:  
  thd->set_current_stmt_binlog_format_row_if_mixed()
in sql_base.cc:lock_tables().

Deployed DBUG_ASSERT before the conditional binlog format
restore.

As part of BUG@39934 fix, the public:
 - THD::current_stmt_binlog_row_based 
variable had been removed and replaced by a private variable:
 - THD::current_stmt_binlog_format. 

THD was refactored and some modifiers and accessors were
implemented for the new variable.

However, due to a bad merge, the
THD::current_stmt_binlog_row_based variable is back as a public
member of THD. This in itself is already potentially
harmful. What's even worse is that while merging some more
patches and resolving conflicts, the variable started being used
again, which is obviously wrong.

To fix this we:
  1. remove the extraneous variable from sql_class.h
  2. revert a bad merge for BUG#49132
  3. merge BUG#49132 properly again (actually, making use of the
     cset used to merge the original patch to mysql-pe).

2. Update test result files.

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.

  fulltext search and row op.

The search for fulltext indexes is searching for some special 
predicate layouts. While doing so it's not checking for the number
of columns of the expressions it tries to calculate.
And since row expressions can't return a single scalar value there
was a crash.
Fixed by checking if the expressions are scalar (in addition to 
being constant) before calling Item::val_xxx() methods.

--default-character-set and --character-set-server such
that only the first will give a deprecation warning.
Apart from that, the two options should do the same.

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).

message:
  Bug #48321  CURRENT_USER() incorrectly replicated for DROP/RENAME USER;
              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.
