Remove some more leftovers from the initial removal:
o Update relevant mentions of configure.in throughout
the source code.
o Remove win/configure.js, which at this point just
duplicates logic already present in CMake based build
system.
o Remove support files which relied on the autotools
build system. In any case, MySQL is no longer officially
supported on SCO.
o Remove files which are no longer part of the build.
The autotools-based build system has been superseded and
is being removed in order to ease the maintenance burden on
developers tweaking and maintaining the build system.
In order to support tools that need to extract the server
version, a new file that (only) contains the server version,
called VERSION, is introduced. The file contents are human
and machine-readable. The format is:
MYSQL_VERSION_MAJOR=5
MYSQL_VERSION_MINOR=5
MYSQL_VERSION_PATCH=8
MYSQL_VERSION_EXTRA=-rc
The CMake based version extraction in cmake/mysql_version.cmake
is changed to extract the version from this file. The configure
to CMake wrapper is retained for backwards compatibility and to
support the BUILD/ scripts. Also, a new a makefile target
show-dist-name that prints the server version is introduced.
VERSION:
Add top-level version file.
cmake/mysql_version.cmake:
Get version information from the top-level VERSION file.
Do not cache the version components (MAJOR_VERSION, etc).
Add MYSQL_RPM_VERSION as a replacement for MYSQL_U_SCORE_VERSION.
Quoting from the bug report:
The pstack library has been included in MySQL since version
4.0.0. It's useless and should be removed.
Details: According to its own documentation, pstack only works
on Linux on x86 in 32 bit mode and requires LinuxThreads and a
statically linked binary. It doesn't really support any Linux
from 2003 or later and doesn't work on any other OS.
The --enable-pstack option is thus deprecated and has no effect.
Fix assorted compiler warnings on Mac OS X.
BUILD/SETUP.sh:
Remove -Wctor-dtor-privacy flag to workaround a GCC bug that
causes it to not properly detect that implicitly generated
constructors are always public.

- Removed -%::SCCS/s.% from Makefile.am:s to remove automake warnings
Post-merge fix: remove --with-debug=full, it was only used for safemalloc.
BUILD/compile-pentium-mysqlfs-debug:
Remove build script for a feature that is long gone.
Restore the original behavior of check-cpu with respect to core2.
It isn't used as a actual target processor type, but as a mean to
perform other kinds of architecture checks.
Essentially, the problem is that safemalloc is excruciatingly
slow as it checks all allocated blocks for overrun at each
memory management primitive, yielding a almost exponential
slowdown for the memory management functions (malloc, realloc,
free). The overrun check basically consists of verifying some
bytes of a block for certain magic keys, which catches some
simple forms of overrun. Another minor problem is violation
of aliasing rules and that its own internal list of blocks
is prone to corruption.
Another issue with safemalloc is rather the maintenance cost
as the tool has a significant impact on the server code.
Given the magnitude of memory debuggers available nowadays,
especially those that are provided with the platform malloc
implementation, maintenance of a in-house and largely obsolete
memory debugger becomes a burden that is not worth the effort
due to its slowness and lack of support for detecting more
common forms of heap corruption.
Since there are third-party tools that can provide the same
functionality at a lower or comparable performance cost, the
solution is to simply remove safemalloc. Third-party tools
can provide the same functionality at a lower or comparable
performance cost.
The removal of safemalloc also allows a simplification of the
malloc wrappers, removing quite a bit of kludge: redefinition
of my_malloc, my_free and the removal of the unused second
argument of my_free. Since free() always check whether the
supplied pointer is null, redudant checks are also removed.
Also, this patch adds unit testing for my_malloc and moves
my_realloc implementation into the same file as the other
memory allocation primitives.
client/mysqldump.c:
Pass my_free directly as its signature is compatible with the
callback type -- which wasn't the case for free_table_ent.
Apart strict-aliasing warnings, fix the remaining warnings
generated by GCC 4.4.4 -Wall and -Wextra flags.
One major source of warnings was the in-house function my_bcmp
which (unconventionally) took pointers to unsigned characters
as the byte sequences to be compared. Since my_bcmp and bcmp
are deprecated functions whose only difference with memcmp is
the return value, every use of the function is replaced with
memcmp as the special return value wasn't actually being used
by any caller.
There were also various other warnings, mostly due to type
mismatches, missing return values, missing prototypes, dead
code (unreachable) and ignored return values.
BUILD/SETUP.sh:
Remove flags that are implied by -Wall and -Wextra.
Do not warn about unused parameters in C++.
BUILD/check-cpu:
Print only the compiler version instead of verbose banner.
Although the option is gcc specific, the check was only
being used for GCC specific checks anyway.
