This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.
The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.
POSIX is enabled. This prevents the toolbox glue, all of Carbon,
and various other non-POSIX features from compiling. The POSIX
symbols are still used by default, so turning off the #define
doesn't hurt.
Additionally, linker flags have changed for Darwin 8, and are
different for Darwin 8/gcc4 (default) and Darwin 8/gcc3.3.

directories) and the include directories specified in CPPFLAGS (``-I``
directories) for compiling the extension modules.
This has led to the core being compiled with the values in the shell's
CPPFLAGS. It has also removed the need for special casing to use Fink and
DarwinPorts under darwin since the needed directories can now be specified in
LDFLAGS and CPPFLAGS (e.g., DarwinPorts users can now do
``LDFLAGS=-L/opt/local/lib; CPPFLAGS=-I/opt/local/include; ./configure`` for
everything to work properly).
Parsing the values in the environment variables is done with getopt. While optparse
would have been a nicer solution it cannot be used because of dependency issues
at execution time; optparse uses gettext which uses struct which will not have
been compiled when the code is imported. If optparse ever makes its
importation of gettext optional by catching ImportError and setting _() to an
identity function then it can be used.
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.

- In the top level Makefile, the argument to -install_name should be
prepended with /System/Library/Frameworks/, so it is an absolute path.
- In the top level Makefile, because of 2), RUNSHARED needs to be set to

Adding plat-mac is still done with a .pth file which is only created when

This adds @CFLAGS@ and @CPPFLAGS@ to the end of the respective

Immediate benefit: when you use "make -t" to avoid a global recompile

Most of the hard work is done by Mac/OSX/Makefile.
Also, it should now be possible to install in a different directory,

- Do framework builds with a twolevel namespace.
- Reorganized the code that creates the minimal framework in the build

earlier aborted builds, or builds of previous Python versions).
This patch fixes make install for Cygwin. Specifically,
it reverts to the previous behavior:
o install libpython$(VERSION)$(SO) in $(BINDIR)
o install $(LDLIBRARY) in $(LIBPL)
It also begins to remove Cygwin's dependency on
$(DLLLIBRARY) which I hope to take advantage of
when I attempt to make Cygwin as similar as possible
to the other Unix platforms (in other patches).
I tested this patch under Red Hat Linux 7.1 without
any ill effects.
BTW, I'm not the happiest using the following
test for Cygwin:
test "$(SO)" = .dll
I'm willing to update the patch to use:
case "$(MACHDEP)" in cygwin*
instead, but IMO that will look uglier.
OSX framework build process. Things fixed/modified:
- the filesystem case-sensitivity test now works for builds outside
the source directory
- various other fixes for building outside the source directory
- python.app now has a target in the main Makefile
- WASTE and AquaTk are found more automatically
This patch removes a vestige part of the Cygwin make rules
that didn't quite make it over during the flattening of the
Makefiles. In its current form, it creates a def file but
incorrectly calls it libpython$(VERSION).dll.a which
immediately gets overwritten by the next command.
Obviously, this is useless. It appears, it was useless
in the old nested Makefile structure too. :,)
PEP 285. Everything described in the PEP is here, and there is even
some documentation. I had to fix 12 unit tests; all but one of these
were printing Boolean outcomes that changed from 0/1 to False/True.
(The exception is test_unicode.py, which did a type(x) == type(y)
style comparison. I could've fixed that with a single line using
issubtype(x, type(y)), but instead chose to be explicit about those
places where a bool is expected.
Still to do: perhaps more documentation; change standard library
modules to return False/True from predicates.
Also move all _PyMalloc_XXX entry points into obmalloc.c.
The Windows build works fine.
The Unix build is changed here (Makefile.pre.in), but not tested.
No other platform's build process has been fiddled.
1. configure doesn't handle HP-UX release numbers
(e.g., B.11.00), resulting in MACHDEP = "hpuxB".
2. After checking for wchar.h, configure doesn't
include it when checking the size of wchar_t.
(Python 2.2b1 on HP-UX 11.00)
This is a big one, touching lots of files. Some of the platforms
aren't tested yet. Briefly, this changes the return value of the
os/posix functions stat(), fstat(), statvfs(), fstatvfs(), and the
time functions localtime(), gmtime(), and strptime() from tuples into
pseudo-sequences. When accessed as a sequence, they behave exactly as
before. But they also have attributes like st_mtime or tm_year. The
stat return value, moreover, has a few platform-specific attributes
that are not available through the sequence interface (because
everybody expects the sequence to have a fixed length, these couldn't
be added there). If your platform's struct stat doesn't define
st_blksize, st_blocks or st_rdev, they won't be accessible from Python
either.
(Still missing is a documentation update.)
it may depend on. It's really annoying that thread.o doesn't get
rebuilt when the .h file is changed! :-)
The dependency is on *all* the Python/thread_*.h files -- that should
be sufficient and rarely cause unneeded recompilations.
- Do not compile unicodeobject, unicodectype, and unicodedata if Unicode is disabled
- check for Py_USING_UNICODE in all places that use Unicode functions
- disables unicode literals, and the builtin functions
- add the types.StringTypes list
- remove Unicode literals from most tests.
- Made framework builds work for MacOSX. The configure arg is now
"--enable-framework".
- Added an install target frameworkinstall which installs the framework.
- Ripped out Next/OpenStep support, which was broken anyway.
- Made the MacOSX toolbox glue dependant on a --enable-toolbox-glue
configure arg. This should make naked darwin build work again (untested).
A few targets have been added to Makefile.pre.in, and on inspection they
look harmless to non-MacOSX machines, but it is worth checking.

It also adds two new APIs which hopefully make it easier for Python

The changes cause compilation failures in any file in the Python
installation lib directory to cause the install to fail. It looks
like compileall.py intended to behave this way, but a change to
py_compile.py and a separate bug defeated it.
Fixes SF bug #412436
This change affects the test suite, which contains several files that
contain intentional errors. The solution is to extend compileall.py
with the ability to skip compilation of selected files.
NB compileall.py is changed so that compile_dir() returns success only
if all recursive calls to compile_dir() also check success.
think that a command starting with '#' is a comment, so move the one
comment in such a position (in the rule for building $(LIBRARY)) to a
harmless position.
- Add CONFIG_ARGS variable and use it to re-run configure rather than

no defs or lambdas or the defs and lambdas it contains have no free

either is illegal.
Revise the symtable to use a PySymtableEntryObject, which holds all
the revelent information for a scope, rather than using a bunch of
st_cur_XXX pointers in the symtable struct. The changes simplify the

Added new C source file: Python/symtable.c. (Does the Windows build

As part of these changes, the initial _symtable module interface
introduced in 2.1a2 is replaced. A dictionary of
PySymtableEntryObjects are returned.
