There are some recursive targets that automake generates which reference
DIST_SUBDIRS. It's critical, then, for such subdirs to exist even if they
won't be built as part of SUBDIRS.
During a VPATH build, it is the configure script which creates the subdirs
(when it processes the AC_CONFIG_FILES() for each subdir's Makefile). If
autoconf doesn't create a subdir's Makefile, then the recursive make will fail
when it is unable to cd into that subdir.
This isn't a problem in non-VPATH builds, because the subdirs are all present
in the source tarball. So the problem only shows up during 'make distcheck',
which does a VPATH build.
The fix is to look, when configure is being created by autoconf, for any
plugin subdirectories. These are the dynamic subdirectories which need to be
handled specially. It's enough to tell autoconf to generate a Makefile for
any Makefile.am found in the plugin directory - all plugin subdirectories
using automake (i.e., listed in the plugin's DIST_SUBDIRS) will have a
Makefile.am.
This is done by calling 'find'. This means that 'find' must be in the PATH on
the host that is running autoconf. 'find' is NOT needed when calling
configure, so it is not an additional dependency for the user.
Finally, ha_ndbcluster.m4 had called AC_CONFIG_FILES() on all those subdir
Makefiles, but only when the plugin was actually being built. So it didn't
work in the case that NDB was not being built. All of those Makefiles have to
be removed from this static list, since the plugin machinery is now adding
them automatically. autoconf fails if a file is duplicated in
AC_CONFIG_FILES().
Modify plugins.m4 configuration framework so that plugins which are
not built still get added to the source distribution during make dist.
This came up now because we can only build ibmdb2i on i5/OS, and we
can't bootstrap our source dist on that platform. The solution is to
specify DIST_SUBDIRS containing all plugins, separate from SUBDIRS
which contains the plugins which are actually built.
This ibmdb2i code is from the ibmdb2i-ga3-src.zip file, with a patch
to plug.in to disable the plugin if the PASE environment isn't available.
Add #define HAVE_CHARSET_name in config-win.h for all character sets that MySQL
supports. Add comments to config/ac-macros/character_sets.m4 and config-win.h
so hopefully they will be updated in sync.
- Removed some copy/paste between debug and normal build in RPM spec
- Removed "mysql_upgrade_shell" from RPM build
- Removed use of "grep -q" in "configure.in", not portable
- Improved test to disable ABI check not to accidently run for icc
Other changes
- Added make file test targets 'test-bt-fast' and 'test-bt-debug-fast'
- Reenabled "jp" test suite run

Problem:
Improper compile-time flags on AIX prevented use of files > 2 GB. This
resulted in Max_data_length being truncated to 2 GB by MyISAM code.
Solution:
Reverted large-file changes from the fix for bug10776. We need to define
_LARGE_FILES on AIX to have support for files > 2 GB.
Since _LARGE_FILE_API is incompatible with _LARGE_FILES and may be
automatically defined by including standards.h, we also need a
workaround to avoid this conflict.

Reverted large-file changes from the fix for bug10776. We need to define

include/my_global.h:
_LARGE_FILE_API is defined in standards.h that is automatically included
by at least some C++ compilers on AIX. Since it is also incompatible
with _LARGE_FILES which is required for POSIX IO calls to be
largefile-safe, the only workaround is to explicitely #undef
_LARGE_FILE_API.

to find "ar" but if it cannot be found sets AR=false. This
leads to confusing failures during the build rather than at
configure time.
We have our own checks for ar, but as AR was already set
earlier by the libtool tests they were never exectuted.
Therefore, update the tests so that we catch any libtool
failures, and run AC_CHECK_PROG explicitly to ensure that we
see sensible output from configure prior to any potential
failure.
config/ac-macros/misc.m4:
AC_CHECK_PROG does nothing if the first argument (variable) is
already set, so remove redundant check for the empty string.
This also ensures that a 'checking for ar' message is printed
prior to any failure, which is far less confusing.
