which was detected during the build of 5.5.3-m3.
This requires version 9 of IBM C++ to help.

More fixes will still be needed, it is very strict
(or rather: a bit picky?) about templates.

about handling the debug plugin files,
also "ha_example.*" are dropped.

archive storage engine headers don't include my_global.h first


During the build of 5.5.3-m3 on older Linux platforms
(kernels 2.4 or early 2.6),
the symptom described in the bug report occurred both
in the "archive" and in the "innobase" storage engine.

This change is the patch proposed in that bug report,
and a similar one in innobase, that latter is aligned
with Vasil Dimov of Innobase, the original author.

as found necessary during the release build of 5.5.3-m3.

scripts/CMakeLists.txt:
  The scripts "mysqldumpslow" and "mysqlhotcopy" need to be handled.
scripts/make_win_bin_dist:
  1) We do not create ".map" files any more.
  
  2) Typing error fixed, it isn't "$DISTDIR" but "$DESTDIR".
  
  3) Security fix:
     If the argument isn't of the form "dst=src",
     then we want the variables to be empty.
  The original code would have used an argument "foo"
  to set both "$src" and "$dst" to this string,
  which doesn't make much sense.

A variable declaration was preceded by "DBUG_PRINT()".

sql-common/client.c:
  Thou shalt not declare a variable after an executable statement
  (and "DBUG_PRINT()" is executable).

extracted from a work-in-progress development branch
just for the build of 5.5.3-m3.

The "cmake" way still shows issues in our release build environment.
Block it temporarily, but in a way that can easily be undone.

This change is to be reverted once the problems are solved.

BUILD/choose_configure.sh:
  Easiest way: Preset "HAVE_CMAKE=no"

There are two issues fixed here:

  1. We needed to update the result file, for some of 
     mysqlbinlog_* tests, because now the some padding chars
     are not output anymore.

  2. We needed to change the Field_string::pack so that
     for BINARY types the padding chars are not packed 
     (lengthsp will return full length for these types).

The problem is introduced by WL#4435 "Support OUT-parameters in 
prepared statements".
When a statement that has out parameters was reprepared,
the reprepare request error was ignored, and an
attempt to send out parameters to the client was made.

Since the out parameter list was not initialized in case
of an error, this attempt led to a crash.

Don't try to send out parameters to the client
if an error occurred in statement execution.

sql/sql_prepare.cc:
  Don't try to send out parameters if error.
tests/mysql_client_test.c:
  Re-enable the test case for Bug#49972.

- Fixing crash on attempt to create a fulltext index with an utf8mb4 column
- fixing wrong border width  for supplementary characters in mysql client:

  mysql --default-character-set=utf8mb4 -e "select concat(_utf32 0x20000,'a')"

Split rpl_row_charset into:

  - rpl_row_utf16.
  - rpl_row_utf32.

This way these tests can run independently if server supports
either one of the charsets but not both.

Cleaned up rpl_row_utf32 which had a spurious instruction:
-- let $reset_slave_type_conversions= 0

In BUG#51787 we were using the wrong charset to print out the
data. We were using the field charset for the string that would
hold the information. This caused the assertion, because the
string length was not aligned with UTF32 bytes requirements for
storage.

We fix this by using &my_charset_latin1 in the string object
instead of the field->charset(). As a side-effect, we needed to
extend the show_sql_type interface so that it took the field
charset is now passed as a parameter, so that one is able to
calculate the correct field size.

In BUG#51716 we had issues with Field_string::pack and
Field_string::unpack. When packing, the length was incorrectly
calculated. When unpacking, the padding the string would be
padded with the wrong bytes (a few bytes less than it should).

We fix this by resorting to charset abstractions (functions) that
calculate the correct length when packing and pad correctly the
string when unpacking.

LOCK kills the server.

Prohibit FLUSH TABLES WITH READ LOCK application to views or
temporary tables.
Fix a subtle bug in the implementation when we actually
did not remove table share objects from the table cache after 
acquiring exclusive locks.

mysql-test/r/flush.result:
  Update results (Bug#51710)
mysql-test/t/flush.test:
  Add a test case for Bug#51710.
sql/sql_parse.cc:
  Fix Bug#51710 "FLUSH TABLES <view> WITH READ LOCK
  killes the server.
  Ensure we don't open views and temporary tables.
  Fix a yet another bug in the implementation which 
  did not actually remove the tables from cache after acquiring
  exclusive locks.

The problem was that in read only mode (read_only enabled),
the server would mistakenly deny data modification attempts
for temporary tables which belong to a transactional storage
engine (eg. InnoDB).

The solution is to allow transactional temporary tables to be
modified under read only mode. As a whole, the read only mode
does not apply to any kind of temporary table.


mysql-test/r/read_only_innodb.result:
  Add test case result for Bug#33669
mysql-test/t/read_only_innodb.test:
  Add test case for Bug#33669
sql/lock.cc:
  Rename mysql_lock_tables_check to lock_tables_check and make
  it static. Move locking related checks from get_lock_data to
  lock_tables_check. Allow write locks to temporary tables even
  under read-only.

    Plugins included into bin release cannot be
    installed on debug version of server

Ensure that the plugin files of the debug build
get into the optimized tree, so that they find
their way into the final RPMs.


support-files/mysql.spec.sh:
  Use "make install" in the debug build tree to get the debug
  plugin files to a temporary location,
  then move them to "plugin/debug/" in the optimized build tree
  so that the install hook in "plugin/Makefile.am" forwards them
  into the final installation.
  
  This fixes bug#49022 for the generic RPMs.
  
  Unrelated:
  The plugin objects were listed twice in the file list,
  do a cleanup.

    Plugins included into bin release cannot be
    installed on debug version of server

IF    the build process was split into separate "debug" and
      "optimized" builds
   AND
      the plugin files of the debug build got copied into
      "plugin/debug/"
(both is done for MySQL release builds starting from 5.5.3),
THEN these debug plugin files are to be included in the
     final binary package.

This change deals with the inclusion only,
the other parts are done in different changesets.


plugin/Makefile.am:
  The "install" rule must not assume that "debug" files are
  present, this depends on the preceding steps in the build.
  
  If they are present, we cannot copy them by simply using
  "libtool install" (as we could do during an ordinary build)
  because they are already kept in "plugin/debug/".
  
  When doing the copy to the destination hierarchy, we must
  ensure that symlinks are not expanded but rather copied
  as symlinks.
  "cp -d" is specific to GNU, the portable way would use
  "cp -P", but that is not fully specified with recursion.
  So we fall back on "tar c | tar x", which is known to
  keep symlinks unchanged (and un-expanded).
  
  Using "$(TAR)" is just a precaution in case of weird path
  settings or other portability issues.
