Make a qualified guess: if $basedir/lib does not exist but $basedir/lib64
  does, then the latter is the proper value for $MYSQL_LIBDIR
Tested on the RPMS of 5.5.12.

Added code to look for repetitions and only repeat warnings once
Reduced time spent in check-warnings by almost 20% for full test suite

                      .editrc on linux.

MySQL client when build with libedit support ignores
.editrc at startup.

The reason for this regression was the incluison of a
safety check, issetugid(), which is not available on
some linux platforms.

Fixed by adding an equivalent check for platforms which
have get[e][u|g]id() set of functions.


cmd-line-utils/libedit/el.c:
  Bug#11757855 - 49967: built-in libedit doesn't read
                        .editrc on linux.
  
  Added function calls to check user/group IDs on linux
  systems which does not have issetugid() function.
configure.in:
  Bug#11757855 - 49967: built-in libedit doesn't read
                        .editrc on linux.
  
  Added check for getuid, geteuid, getgid, getegid
  functions.

(empty, the exact same changes are already in 5.5)

Add extra codes to wait_until_disconnected.inc that are present in 5.5,
but not in 5.1. The missing codes cause innodb_bug59641 to fail in 5.1 on
Windows PB2 runs. The addition of those codes in 5.5 was done in
luis.soares@sun.com-20090930233215-aup3kxy4j6ltvjfp

Removed STDCALL from the function definition.

BEFORE: First packet sent by client-side plugin (generated by Windows
function InitializeSecurityContext()) could be longer than 255 bytes 
violating the limitation imposed by authentication protocol.

AFTER: Handshake protocol is  changed so that if first client's reply is 
longer than 254 bytes then  it is be sent in 2 parts. However, for replies
shorter than 255 bytes nothing changes.

ADDITIONAL CHANGES: 
- The generic packet processing loop  (Handshake::packet_processing_loop) 
has been refactored. Communication with the peer has been abstracted
into virtual methods read/write_packet() which are implemented in client 
and server and transparently do the required splitting and gluing of packets.
- Make it possible to optionally use dbug library in the plugin.
- Add code for testing splitting of long first client reply.

into the server repository

This patch adds client windows authentication plugin code to the client 
library libmysql (only on Windows platform). The plugin is compiled into 
the library and added to the list of built-in plugins. This way clients 
should be able to connect to a server which uses windows authentication 
plugin even as an SQL user which uses such authentication.

Note: this makes the client library to depend on Secur32 Windows system
library. When building clients, they must be linked against Secur32. 
Command mysql_config --libs correctly lists Secur32 as a required 
dependency.

Enabled the ABI check to run on MacOSX.

Partitions can have different ref_length (position data length).
Removed DBUG_ASSERT which crashed debug builds when using
MAX_ROWS on some partitions.

               FAILS WITH LIBEDIT

Fixed by checking the return value of the write()
function calls and handling the open files and fd
appropriately.


cmd-line-utils/libedit/vi.c:
  BUG#12329909 - BUILDING MYSQL WITH DEBUG SUPPORT
                 FAILS WITH LIBEDIT
  
  Added a check on the return value of the write()
  function calls.

 - fix the fix to properly detect when engine is NDB and
   also don't drop the table t9 if it hasn't been created

Fix: it only worked if some worker had valgrind report from its last test
Flag has to be set both places where report is printed

calc_daynr() function returns negative result
if malformed date with zero year and month is used.
Attempt to calculate week day on negative value
leads to crash. The fix is return NULL for
'W', 'a', 'w' specifiers if zero year and month is used.
Additional fix for calc_daynr():
--added assertion that result can not be negative
--return 0 if zero year and month is used


mysql-test/r/func_time.result:
  test case
mysql-test/t/func_time.test:
  test case
sql-common/my_time.c:
  --added assertion that result can not be negative
  --return 0 if zero year and month is used
sql/item_timefunc.cc:
  eturn NULL for 'W', 'a', 'w' specifiers
  if zero year and month is used.

The innoDB global variable srv_lower_case_table_names is set to the value of lower_case_table_names declared in mysqld.h server in ha_innodb.cc.  Since this variable can change at runtime, it is reset for each handler call to ::create, ::open, ::rename_table & ::delete_table.

But it is possible for tables to be implicitly opened before an explicit handler call is made when an engine is first started or restarted.  I was able to reproduce that with the testcase in this patch on a version of InnoDB from 2 weeks ago.  It seemed like the change buffer entries for the secondary key was getting put into pages after the restart.  (But I am not sure, I did not write down the call stack while it was reproducing.)  In the current code, the implicit open, which is actually a call to dict_load_foreigns(), does not occur with this testcase.

The change is to replace srv_lower_case_table_names by an interface function in innodb.cc that retrieves the server global variable when it is needed.
