Protocol documentation (http://forge.mysql.com/wiki/MySQL_Internals_ClientServer_Protocol)
says that initial packet sent by client if client wants SSL, consists of client capability flags only
(4 bytes or 2 bytes edependent on protocol versionl). 
Some clients happen to send more in the initial SSL packet (C client, Python connector), while others (Java, .NET) follow the docs and send only client capability flags.

A change that broke Java client was a newly introduced check that frst client packet
has 32 or more bytes. This is generally wrong, if client capability flags contains CLIENT_SSL.

Also, fixed the code such that read max client packet size and charset in the first packet prior to SSL handshake.  With SSL, clients do not have to send this info, they can only send client flags.

This is now fixed such that max packet size and charset are not read prior to SSL handshake, in case of SSL they are read from the "complete" client authentication packet after SSL initialization.

The cause of this bug was the same as for bug 902356 fixed for 5.3.

sql/sql_parse.cc:
  Only call ha_maria::implicit_commit if aria is enabled

The counter handler_read_key (SSV::ha_read_key_count) is incremented 
incorrectly.

The mysql server maintains a per thread system_status_var (SSV)
object.  This object contains among other things the counter
SSV::ha_read_key_count. The purpose of this counter is to measure the
number of requests to read a row based on a key (or the number of
index lookups).

This counter was wrongly incremented in the
ha_innobase::innobase_get_index(). The fix removes
this increment statement (for both innodb and innodb_plugin).

The various callers of the innobase_get_index() was checked to
determine if anybody must increment this counter (if they first call
innobase_get_index() and then perform an index lookup).  It was found
that no caller of innobase_get_index() needs to worry about the
SSV::ha_read_key_count counter.

SMALL KEY CACHE

The server crashed on division by zero because the key cache was not
initialized and the block length was 0 which was used in a division.

The fix was to not allow CACHE INDEX if the key cache was not initiallized.
Thus never try LOAD INDEX INTO CACHE for an uninitialized key cache.

Also added some windows files/directories to .bzrignore.

When printing information about a ROW_FORMAT=REDUNDANT record, pass
the correct flag to rec_get_next_offs().

Post-push fix: build break on windows/optimized

handle_segfault is the signal handler code of mysqld.  however, it makes
calls to potentially unsafe functions localtime_r, fprintf, fflush.

  Move signal handler to separate file.
mysys/stacktrace.c:

mysql-test/lib/My/Options.pm:
  My::Options::is_set() now matches both option names and values!
mysql-test/lib/mtr_cases.pm:
  1. don't merge --plugin-load here, it's too early
  2. don't skip combinations that set --plugin-load just because the test needs another --plugin-load.
     Skip *only* if test's --plugin-load matches *exactly* --plugin-load of one of the combinations.
  3. if skipping all combinations but one, still assign the test to the combination
mysql-test/mysql-test-run.pl:
  1. remove dead code - don't set variables that aren't used.
  2. bugfix: allow one-letter combination names
  3. in the command line, merge all --plugin-load options in one
storage/federated/ha_federated.cc:
  bugfix: garbage character in the generated SELECT query

We merged the test case for this into MariaDB 5.1, but the fix
was not yet part of XtraDB.

                    WITH MYISAM_USE_MMAP ENABLED

MySQL server can crash due to segmentation fault when
started with myisam_use_mmap.

The reason behind this being, while making a request to
unmap (munmap) the previously mapped memory (mmap), the
size passed was 7 bytes larger than the size requested at
the time of mapping. This can eventually unmap the adjacent
memory mapped block, belonging to some other memory-map pool.
Hence the subsequent call to mmap can map a region which was
still a valid memory mapped area.

Fixed by removing the extra 7-byte margin which was erroneously
added to the size, used for unmappping.


storage/myisam/mi_close.c:
  Bug#11756764 48726: MYSQLD KEEPS CRASHING WITH SIGSEGV
                      WITH MYISAM_USE_MMAP ENABLED
  
  Added a condition to call _mi_unmap_file() in case
  of compressed records. mi_munmap_file() is called
  otherwise.
storage/myisam/mi_packrec.c:
  Bug#11756764 48726: MYSQLD KEEPS CRASHING WITH SIGSEGV
                      WITH MYISAM_USE_MMAP ENABLED
  
  mi_dynmap_file() function, after successfully executing
  mmap, stores the total size in info->s->mapped_length
  variable. Now, if mi_dynmap_file() is invoked with a size
  with an extra 7-byte margin (MEMMAP_EXTRA_MARGIN),
  the margin will eventually also get stored in mapped_length.
  So, un-mapping function can simply use the value stored in
  mapped_length in order to unmap the previously mapped
  region.
