of hard linking against the framework).
If $MACOSX_DEPLOYMENT_TARGET is set, and >= 10.3, during configure we
setup extensions to link with dynamic lookup. We also record the
value in the Makefile.
Distutils checks whether a value for MACOSX_DEPLOYMENT_TARGET was
recorded in the Makefile, and if it was insists that the current
value matches.
This is only a partial fix because it only applies to 2.4, and the
"two python problem" exists with Python 2.3 shipped with MacOSX 10.3,
which we have no influence over.
requires and provides. requires is a sequence of strings, of the
form 'packagename-version'. The dependency checking so far merely
does an '__import__(packagename)' and checks for packagename.__version__
You can also leave off the version, and any version of the package
will be installed.
There's a special case for the package 'python' - sys.version_info
is used, so
requires= ( 'python-2.3', )
just works.
Provides is of the same format as requires - but if it's not supplied,
a provides is generated by adding the version to each entry in packages,
or modules if packages isn't there.
Provides is currently only used in the PKG-INFO file. Shortly, PyPI
will grow the ability to accept these lines, and register will be
updated to send them.
There's a new command 'checkdep' command that runs these checks.
For this version, only greater-than-or-equal checking is done. We'll
add the ability to specify an optional operator later.

Patch #892660 from Mark Hammond, for distutils bdist_wininst command.
install.c: support for a 'pre-install-script', run before anything has
been installed. Provides a 'message_box' module function for use by
either the pre-install or post-install scripts.
bdist_wininst.py: support for pre-install script. Typo (build->built),
fixes so that --target-version can still work, even when the
distribution has extension modules - in this case, we insist on
--skip-build, as we still can't actually build other versions.

Use case: Sometimes 'compiling' source files (with SWIG, for example)
creates additionl files which included by later sources. The win32all
setup script requires this.
There is no SF item for this, but it was discussed on distutils-sig:
http://mail.python.org/pipermail/distutils-sig/2003-November/003514.html
distutils now looks for the compiler version in sys.version, falling
back to MSVC 6 if the version isn't listed (Python 2.2 and lower).
Add helper routines for reading the registry. Refactor many
module functions into methods of the compiler to avoid passing
lots of state as arguments.
On cygwin, the setup.py script uses unixccompiler.py for compiling and linking
C extensions. The unixccompiler.py script assumes that executables do not get
special extensions, which makes sense for Unix. However, on Cygwin,
executables get an .exe extension.
This causes a problem during the configuration step (python setup.py config),
in which some temporary executables may be generated. As unixccompiler.py does
not know about the .exe extension, distutils fails to clean up after itself: it
does not remove _configtest.exe but tries to remove _configtest instead.
The attached patch to unixccompiler.py sets the correct exe_extension for
cygwin by checking if sys.platform is 'cygwin'. With this patch, distutils
cleans up after itself correctly.

After some more reflection (and no negative feedback), I am reverting the
original patch and applying my version, cygwinccompiler.py-shared.diff,
instead.
My reasons are the following:
1. support for older toolchains is retained
2. support for new toolchains (i.e., ld -shared) is added
The goal of my approach is to avoid breaking older toolchains while adding
better support for newer ones.
The cygwinccompiler.get_versions() function only handles versions numbers of
the form "x.y.z". The attached patch enhances get_versions() to handle "x.y"
too (i.e., the ".z" is optional).
This change causes the unnecessary "--entry _DllMain@12" link option to be
suppressed for recent Cygwin and Mingw toolchains. Additionally, it directs
recent Mingw toolchains to use gcc instead of dllwrap during linking.
Currently, the cygwinccompiler.py compiler handling in
distutils is invoking the cygwin and mingw compilers
with the -static option.
Logically, this means that the linker should choose to
link to static libraries instead of shared/dynamically
linked libraries.
Current win32 binutils expect import libraries to have
a .dll.a suffix and static libraries to have .a suffix.
If -static is passed, it will skip the .dll.a
libraries. This is pain if one has a tree with both
static and dynamic libraries using this naming
convention, and wish to use the dynamic libraries.
The -static option being passed in distutils is to get
around a bug in old versions of binutils where it would
get confused when it found the DLLs themselves.
The decision to use static or shared libraries is site
or package specific, and should be left to the setup
script or to command line options.
specified with an absolute path, the object file is also
written to an absolute path. The patch drops the drive and
leading '/' from the source path, so a path like /path/to/foo.c
results in an object file like build/temp.i686linux/path/to/foo.o.
bdist_wininst.py we will see.)
Removed the base64 encoded binary contents, wininst.exe must be in the
same directory as this file now.
wininst.exe must be recompiled and commited each time the sources in
PC/bdist_wininst are changed.
Previously archive_util.py attempted to spawn an
external 'zip' program for the zip action, if this fails, an
attempt to import zipfile.py is made...
This bites folks who have 'old' or non-conforming zip
programs on windows platforms. This change tries the 'zipfile'
module first, falling back to spawning a zip process if
the module isn't available.
If you have source files srcdir1/foo.c and srcdir2/foo.c, the
temporary .o for both files is written to build/temp.<platform>/foo.o.
This patch sets strip_dir to false for both calls to object_filename,
so now the object files are written to temp.<platform>/srcdir1/foo.o
and .../srcdir2/foo.o.
2.2 bugfix candidate
The two long lines have been reflowed differently; hopefully someone on
BeOS can test them. Rev. 1.53 also converted string.atoi() to int(); I've
left that alone.
Fixed by catching all exceptions that are subclasses of DistutilsError,
so only the error message will be printed. You can still get the
whole traceback by enabling the Distutils debugging mode.

whether the Distutils being used supports a particularly capability.
(This idea was originally suggested by Juergen Hermann as a method
on the Distribution class. I think it makes more sense as a
function in core.py, and that's what this patch implements.)
arguments, triggering a warning instead of raising an exception. (In
1.5.2/2.0, it will print to stderr.)
Bugfix candidate for all previous versions. This changes behaviour,
but the old behaviour wasn't very useful. If Distutils version X+1
adds a new keyword argument, using the new keyword means your setup.py
file won't work with Distutils version X any more.
Strangely, two out of three patches there seem already committed; but
the essential one (get rid of the assert in object_filenames in
ccompiler.py) was not yet applied.
This makes the build procedure for Twisted work again.
This is *not* a backport candidate despite the fact that identical
code appears to exist in 2.2.2; Twisted builds fine there, so there
must have been a change elsewhere.
The default implementation calls _compile() to compile individual
files. This method must be implemented by the subclass. This change
factors out most of the remaining common code in all the compilers
except mwerks.
Two new tests are needed:
Don't skip building an extension if any of the depends files are newer
than the target.
Pass ext.depends to compiler.compile() so that it can track individual
files.
Always use _setup_compile() to do the grunt work of processing
arguments, figuring out which files to compile, and emitting debug
messages for files that are up-to-date.
Use _get_cc_args() when possible.
This change is not backwards compatible. If a compiler subclass
exists outside the distutils package, it may get called with the
unexpected keyword arg. It's easy to extend that compiler by having
it ignore the argument, and not much harder to do the right thing. If
this ends up being burdensome, we can change it before 2.3 final to
work harder at compatibility.
Also add _setup_compile() and _get_cc_args() helper functions that
factor out much of the boilerplate for each concrete compiler class.
Remove __init__ that just called base class __init__ with same args.
Fold long argument lists into fewer, shorter lines.
Remove parens in tuple unpacks.
Don't put multiple statements on one line with a semicolon.
In find_library_file() compute the library_filename() upfront.
