  Bug#53593: Add some instrumentation to improve Valgrind sensitivity

  BUILD/*: Add valgrind_configs=--with-valgrind.
  BUILD/*: Remove -USAFEMALLOC from valgrind_flags.

  configure.in: Add AC_ARG_WITH(valgrind) and HAVE_VALGRIND.

  include/my_sys.h: Define a number of MEM_ wrappers for VALGRIND_ functions.
  include/my_sys.h: Make TRASH do MEM_UNDEFINED().

  include/m_string.h: Remove unused macro bzero_if_purify(A,B).

  _mymalloc(): Declare MEM_UNDEFINED() on the allocated memory.

  _myfree(): Declare MEM_NOACCESS() on the freed memory.

  storage/innobase/include/univ.i: Enable UNIV_DEBUG_VALGRIND based on
  HAVE_VALGRIND rather than HAVE_purify.

  Possible things to do:
   * In my_global.h, remove the defined(HAVE_purify) condition
     from the _WIN32 uint3korr().
   * In my_global.h *int*korr(), use | instead of +
     in order to keep the Valgrind V bits accurate
   * Consider replacing HAVE_purify with HAVE_VALGRIND
   * Use VALGRIND_CREATE_BLOCK, VALGRIND_DISCARD in mem_root and similar places

4d7b6a6ea1 Automerge MySQL 5.1.44 merge into latest MariaDB trunk. 2010-03-10 10:12:23 +01:00
Michael Widenius
292f6568fa Added count of my_sync calls (to SHOW STATUS)
tmp_table_size can now be set to 0 (to disable in memory internal temp tables)
Improved speed for internal Maria temp tables:
- Don't use packed keys, except with long text fields.
- Don't copy key all accessed pages during key search.
Some new benchmark tests to sql-bench (for group by)

BUILD/compile-pentium64-gcov:
  Update script to use same pentium_config flags as other tests
BUILD/compile-pentium64-gprof:
  Update script to use same pentium_config flags as other tests
include/my_sys.h:
  Added count of my_sync calls
mysql-test/r/variables.result:
  tmp_table_size can now be set to 0
sql-bench/test-select.sh:
  Added some new test for GROUP BY on a not key field and group by with different order by
sql/mysqld.cc:
  Added count of my_sync calls
  tmp_table_size can now be set to 0 (to disable in memory internal temp tables)
sql/sql_select.cc:
  If tmp_table_size is 0, don't use in memory temp tables (good for benchmarking MyISAM/Maria temp tables)
  Don't pack keys for Maria tables;  The 8K page size makes packed keys too slow for temp tables.
storage/maria/ma_key_recover.h:
  Moved definition to maria_def.h
storage/maria/ma_page.c:
  Moved code used to simplify comparing of identical Maria tables to own function (page_cleanup())
  Fixed that one can read a page with a read lock.
storage/maria/ma_rkey.c:
  For not exact key reads, cache the page where we found key (to speed up future read-next/read-prev calls)
storage/maria/ma_search.c:
  Moved code to cache last key page to separate function.
  Instead of copying pages, only get a link to the page. This notable speeds up key searches on bigger tables.
storage/maria/ma_write.c:
  Added comment
storage/maria/maria_def.h:
  Moved page_cleanup() to separate function.

600a283689 Bug #45058 init_available_charsets uses double checked locking
A client doing multiple mysql_library_init() and
mysql_library_end() calls over the lifetime of the process may
experience lost character set data, potentially even a
SIGSEGV.

This patch reinstates the reloading of character set data when
a mysql_library_init() is done after a mysql_library_end().

8969530cff Bug #45058 init_available_charsets uses double checked locking
As documented in the bug report, the double checked locking
pattern has inherent issues, and cannot guarantee correct
initialization.

This patch replaces the logic in init_available_charsets()
with the use of pthread_once(3). A wrapper function,
my_pthread_once(), is introduced and is used in lieu of direct
calls to init_available_charsets(). Related defines
MY_PTHREAD_ONCE_* are also introduced.

For the Windows platform, the implementation in lp:sysbench is
ported. For single-thread use, a simple define calls the
function and sets the pthread_once control variable.

Charset initialization is modified to use my_pthread_once().

include/my_no_pthread.h:
  Dummy my_pthread_once() for single thread use.
include/my_pthread.h:
  Declaration for new function my_pthread_once().
mysys/charset.c:
  Logic in init_available_charsets() is simplified. 
  Using my_pthread_once() for all calls to this func.
mysys/my_winthread.c:
  Windows implementation of my_pthread_once().
