"Patch to fix bug 38551": it was a manual backport (2008-10-15) of
http://lists.mysql.com/commits/56418.
But that was an early, non-final patch from the fixer of this bug (TheK):
after that backport was made by Mikael, TheK decided to do a different fix,
which was finally pushed into 6.0.
Then 5.1's code was changed for some other reasons, so now we have a
conflict between the old never-approved TheK patch backported to Summit and
the latest 5.1. The backport cannot stay, it has to be removed due to
the conflict, and then rewritten if desired.

bzr branch mysql-5.1-performance-version mysql-trunk # Summit
cd mysql-trunk
bzr merge mysql-5.1-innodb_plugin # which is 5.1 + Innodb plugin 
bzr rm innobase # remove the builtin
Next step: build, test fixes.

Reverted lost in the merge line.

Part of the 'show status' code was erronously removed when the google
	patch was applied.  This patch puts it back.

The NULL return from tree_insert() (on low memory) was not
checked for in Item_func_group_concat::add(). As a result
on low memory conditions a crash happens.

Fixed by properly checking the return code.

Fix Bug#21704 Renaming column does not update FK definition

by checking whether a column that participates in a FK definition is being
renamed and denying the ALTER in this case.

The patch was originally developed by Davi Arnaut <Davi.Arnaut@Sun.COM>:
http://lists.mysql.com/commits/77714
and was later adjusted to conform to InnoDB coding style by me (Vasil),
I also added some more comments and moved the bug specific mysql-test to
a separate file to make it more manageable and flexible.

            and base tables 

myrg_attach_children() could reuse a buffer that was allocated 
previously based on a definition of a child table. The problem 
was that the child's definition might have been changed, so 
reusing the buffer could lead to crashes or valgrind errors 
under some circumstances. 
 
Fixed by changing myrg_attach_children() so that the 
rec_per_key_part buffer is reused only when the child table
have not changed, and reallocated otherwise (the old buffer is 
deallocated if necessary).


include/myisammrg.h:
  Added a pointer to need_compat_check as an argument to
  myrg_attach_children().
mysql-test/r/merge.result:
  Added a test case for bug #45796.
mysql-test/t/merge.test:
  Added a test case for bug #45796.
storage/myisammrg/ha_myisammrg.cc:
  Pass a pointer to need_compat_check to myrg_attach_children().
storage/myisammrg/myrg_open.c:
  Changed myrg_attach_children() so that the 
  rec_per_key_part buffer is reused only when the child table
  have not changed, and reallocated otherwise (the old buffer 
  is deallocated if necessary).

branches/5.1: Add missing #include "mtr0log.h" to avoid warnings
when compiling with -DUNIV_MUST_NOT_INLINE.

- when finding out a way to hide symbols, make decision basing
  on compiler, not operating system.
- Sun Studio supports __hidden declaration specifier for this
  purpose.

unnecessarily
      
The problem is that libmysqlclient.so is built with THREAD
undefined, while a client compiling against the same header
files will see THREAD as defined and definitions in
my_pthread.h will be included, possibly resulting in undefined
symbols that cannot be resolved with libmysqlclient.so.
      
The suggested solution is to require that clients wanting to
link with libmysqlclient.so should be built with
MYSQL_CLIENT_NO_THREADS defined. This requires a documentation
change, and more details for this will be supplied if this
patch is approved.
      
The MYSQL_CLIENT_NO_THREADS define was renamed from
UNDEF_THREADS_HACK, to get a more suitable (less suspicious)
name for the define. (The UNDEF_THREADS_HACK is retained for
backwards compatibility, though.)
      
This patch is also in anticipation of WL#4958, which will
remove this problem altogether by dropping the building of
libmysqlclient.
