Implement a check whether pthread_t objects can be used by GCC atomic
builtin functions. This check is implemented in plug.in and defines the
macro HAVE_ATOMIC_PTHREAD_T. This macro is checked in univ.i and the
relevant part of the code enabled (the one that uses GCC atomics against
pthread_t objects).

In addition to this, the same program that is compiled as part of the
plug.in check is added in ut/ut0auxconf.c. In the InnoDB Plugin source
archives that are shipped to the users, a generated Makefile.in is added.
That Makefile.in will be modified to compile ut/ut0auxconf.c and define
the macro HAVE_ATOMIC_PTHREAD_T if the compilation succeeds. I.e.
Makefile.in will emulate the work that is done by plug.in. This is done in
order to make the check happen and HAVE_ATOMIC_PTHREAD_T eventually
defined without regenerating MySQL's ./configure from
./storage/innobase/plug.in. The point is not to ask users to install the
autotools and regenerate ./configure.

Fix typo made in r4353.

As suggested by Ken, print a message that says that the Google SMP patch
(GCC atomics) is disabled if it is. Also extend the message when the patch
is partially enabled to make it clear that it is partially enabled.

Add FreeBSD to the list of the operating systems that have
sizeof(pthread_t) == sizeof(void*) (i.e. word size).

On FreeBSD pthread_t is defined like:

  /usr/include/sys/_pthreadtypes.h:

  typedef struct  pthread                 *pthread_t;

I did the following tests (per Inaam's recommendation):

a) appropriate version of GCC is available on that platform (4.1.2 or
higher for atomics to be available)

  On FreeBSD 6.x the default compiler is 3.4.6, on FreeBSD 7.x the default
  one is 4.2.1. One can always install the version of choice from the ports
  collection. If gcc 3.x is used then HAVE_GCC_ATOMIC_BUILTINS will not be
  defined and thus the change I am committing will make no difference.

b) find out if sizeof(pthread_t) == sizeof(long)

  On 32 bit both are 4 bytes, on 64 bit both are 8 bytes.

c) find out the compiler generated platform define (e.g.: __aix, __sunos__
etc.)

  The macro is __FreeBSD__.

d) patch univ.i with the appropriate platform define
e) build the mysql
f) ensure it is using atomic builtins (look at the err.log message at
system startup. It should say we are using atomics for both mutexes and
rw-locks)
g) do sanity testing (keeping in view the smp changes)

  I ran the mysql-test suite. All tests pass.

This is a fix for issue#178. Instead of using UNIV_LINUX which is
defined through CFLAGS we use compiler generated define __linux__
that is effective for both .c and .cc files.

This is to revert the changes made to the plug.in (r4251) as a fix for
issue# 178. Changes to plug.in will not propogate to a plugin
installation unless autotools are rerun which is unacceptable.

A fix for issue# 178 will be committed in a separate commit.

FIL_PAGE_TYPE mismatch even when purging a BLOB.
Heavy users may have large data files created with MySQL 5.0 or earlier,
and they don not want to have the error log flooded with such messages.

This fixes Issue #182.

Apply any necessary patches to the mysql tree at the end of setup.sh
This step was previously done manually (and sometimes forgotten).

Do not output the commands that restore the environment because they depend
on the state of the environment before the test starts executing.

White-space cleanup in the ChangeLog

again, to finally put Issue #181 to rest.

Revert some parts of r4274.  It is best not to call ut_malloc() before
srv_general_init().

mem_init(): Do not call ut_mem_init().

srv_general_init(): Initialize the memory subsystem in two phases:
first ut_mem_init(), then mem_init().  This is because os_sync_init()
and sync_init() depend on ut_mem_init() and mem_init() depends on
os_sync_init() or sync_init().

srv_parse_data_file_paths_and_sizes(),
srv_parse_log_group_home_dirs(): Remove the output parameters.  Assign
to the global variables directly.  Allocate memory with malloc()
instead of ut_malloc(), because these functions will be called before
srv_general_init().

srv_free_paths_and_sizes(): New function, for cleaning up after
srv_parse_data_file_paths_and_sizes() and
srv_parse_log_group_home_dirs().

Fix Bug synopsis and remove explanation

Make ChangeLog entries for bugs in bugs.mysql.com in the form:
Fix Bug#12345 bug title
(for bugs after 1.0.2 was released and the ChangeLog published)

There is no need to bloat the ChangeLog with information that is available
via bugs.mysql.com.

Discussed with:	Marko

Add ChangeLog entry for the fix in r4288.

  branches/5.1: Fix Bug#42714 AUTO_INCREMENT errors in 5.1.31. There are two
  changes to the autoinc handling.
  
  1. To fix the immediate problem from the bug report, we must ensure that the
     value written to the table is always less than the max value stored in
     dict_table_t.
  
  2. The second related change is that according to MySQL documentation when
     the offset is greater than the increment, we should ignore the offset.
  
  ------------------------------------------------------------------------

outside Valgrind, with innodb_use_sys_malloc set to 0 and 1.

mem_init(): Invoke ut_mem_init() before mem_pool_create(), because
the latter one will invoke ut_malloc().

srv_general_init(): Do not initialize the memory subsystem (mem_init()).

innobase_init(): Initialize the memory subsystem (mem_init()) before
calling srv_parse_data_file_paths_and_sizes(), which needs ut_malloc().
Call ut_free_all_mem() in error handling to clean up after the mem_init().

btr_check_blob_fil_page_type(): Replace the parameter
const char* op
with
ibool read.  Do not print anything about page type mismatch
when reading a BLOB page in Antelope format.
Print space id before page number.

FIL_PAGE_TYPE.  (Bug #43043, Issue #182)

btr_check_blob_fil_page_type(): New function.

btr_free_externally_stored_field(), btr_copy_blob_prefix():
Call btr_check_blob_fil_page_type() to check FIL_PAGE_TYPE.

ut_list_mutex would be used uninitialized when innodb_use_sys_malloc=1.
This fix addresses Issue #181.

ut_mem_block_list_init(): Rename to ut_mem_init() and make public.

ut_malloc_low(), ut_free_all_mem(): Add ut_a(ut_mem_block_list_inited).

mem_init(): Call ut_mem_init().

Add a sentence at the top of COPYING.Google to clarify that this license
does not apply to the whole InnoDB.

Suggested by:	Ken

Replace srv_use_sys_malloc with UNIV_LIKELY(srv_use_sys_malloc)
to improve branch prediction in the default case.

ChangeLog: Remove include/os0sync.ic from the entry about the google patch,
this file was modified later to not include Google's code.

Cleanup in ChangeLog:
* Wrap lines at 78 characters
* Changed files are listed alphabetically
* White-space cleanup

Change plug.in to have same CXXFLAGS as CFLAGS. This is to ensure that
both .c and .cc files get compiled with same flags. To fix the issue
where UNIV_LINUX was defined only in .c files.

Approved by: Marko

about an empty body in a "for" statement.  This closes Issue #176.

Unprotected updates to ut_total_allocated_memory in
os_mem_alloc_large() and os_mem_free_large(), called during
fast index creation, may corrupt the variable and cause assertion failures.

Also, add UNIV_MEM_ALLOC() and UNIV_MEM_FREE() instrumentation around
os_mem_alloc_large() and os_mem_free_large(), so that Valgrind can
detect more errors.

rb://90 approved by Heikki Tuuri.  This addresses Issue #177.

about an empty body of a "for" statement.
This fixes part of Issue #176.

about a while(0); statement.  This should fix (part of) Issue #176.

lock->writer_thread invalid, so that Valgrind will catch more errors.
This is related to Issue #175.

sync_array_object_signalled(): Add a (void) cast to eliminate a gcc warning
about the return value of os_atomic_increment() being ignored.

rw_lock_create_func(): Properly indent the preprocessor directives.

rw_lock_x_lock_low(), rw_lock_x_lock_func_nowait(): Split lines correctly.

rw_lock_set_writer_id_and_recursion_flag(): Silence a Valgrind warning.
Do not mix statements and variable declarations.
