  Bug#53578: assert on invalid page access, in fil_io()

  Store the max_space_id in the data dictionary header in order to avoid
  space_id reuse.

  DICT_HDR_MIX_ID: Renamed to DICT_HDR_MAX_SPACE_ID, DICT_HDR_MIX_ID_LOW.

  dict_hdr_get_new_id(): Return table_id, index_id, space_id or a subset of them.

  fil_system_t: Add ibool space_id_reuse_warned.

  fil_create_new_single_table_tablespace(): Get the space_id from the caller.

  fil_space_create(): Issue a warning if the fil_system->max_assigned_id
  is exceeded.

  fil_assign_new_space_id(): Return TRUE/FALSE and take a pointer to the
  space_id as a parameter. Make the function public.

  fil_init(): Initialize all fil_system fields by mem_zalloc(). Remove
  explicit initializations of certain fields to 0 or NULL.

Also explain in the comment the units of the "offset" parameter

It is wrong to tell the OS that a block is not going to be accessed and
write to it immediately afterwards.

to crash) from mysql-6.0-codebase.

The thing is that on some platforms (e.g. Mac OS X) sockaddr_in / sockaddr_in6
contain a non-standard field (sin_len / sin6_len), that must be set.

The problem was that only standard fields were set, thus getnameinfo() returned
EAI_SYSTEM instead of EAI_NONAME.

The fix is to introduce configure-time checks (for GNU auto-tools and CMake) for
those additional fields and to set them if they are available.

FOR UPDATE is causing a lock".
 
This patch tries to address problems which were exposed 
during backporting of original patch to 5.1 tree.
 
- It ensures that we don't change locking behavior of simple
  SELECT statements on InnoDB tables when they are executed
  under LOCK TABLES ... READ and with @@innodb_table_locks=0.
  Also we no longer pass TL_READ_DEFAULT/TL_WRITE_DEFAULT 
  lock types, which are supposed to be parser-only, to 
  handler::start_stmt() method.
- It makes check_/no_concurrent_insert.inc auxiliary scripts 
  more robust against changes in test cases that use them
  and also ensures that they don't unnecessarily change 
  environment of caller.

mysql-test/include/check_concurrent_insert.inc:
  Reset DEBUG_SYNC facility before and after using it in
  auxiliary script. This makes this script more robust against
  changes in test cases calling it. It also ensures that script
  does not unnecessarily change environment of caller.
mysql-test/include/check_no_concurrent_insert.inc:
  Reset DEBUG_SYNC facility before and after using it in
  auxiliary script. This makes this script more robust against
  changes in test cases calling it. It also ensures that script
  does not unnecessarily change environment of caller.
mysql-test/r/innodb-lock.result:
  Added coverage for LOCK TABLES ... READ behavior in
  @@innodb_table_locks = 0 mode. This test also checks
  that an appropriate type of lock is passed to
  handler::start_stmt() method.
mysql-test/t/innodb-lock.test:
  Added coverage for LOCK TABLES ... READ behavior in
  @@innodb_table_locks = 0 mode. This test also checks
  that an appropriate type of lock is passed to
  handler::start_stmt() method.
sql/sql_base.cc:
  Since we no longer set TL_READ as lock type for tables used  
  in simple SELECT right in the parser, in order to preserve  
  behavior for such statements on InnoDB tables when in  
  LOCK TABLES mode with @innodb_table_locks = 0,  
  check_lock_and_start_stmt() had to be changed to convert  
  TL_READ_DEFAULT to an appropriate type of read lock before  
  passing it to handler::start_stmt() method.  
  We do similar thing for TL_WRITE_DEFAULT as this lock type  
  is also supposed to be parser-only type.  
  As consequence read_lock_type_for_table() had to be  
  adjusted to behave properly when it is called from  
  check_lock_and_start_stmt() in prelocked mode.

  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

(make relies GNU extentions). The patch was partially
backport from 6.0.

Original comment:
bug#30708: make relies GNU extensions.  Now that we no longer use
BitKeeper we can safely remove the SCCS handling with no loss of
functionality.

from 6.0 to trunk-bugfixing.

The problem was that OPTMIZE TABLE was allowed to run on a table
in use by a transaction in a different connection. This caused
repeatable read to break.

This bug was fixed by the introduction of metadata locking, WL#4284.
OPTIMIZE TABLE will now be blocked until the transaction using the
table, has ended.

This patch contains a regression test added to innodb_mysql_lock.test
and no code changes.
