isn't checked, and it *is* possible that a very large alloca() call is
made, e.g. when a large registry value is being read. I don't know if
alloca() in that case returns NULL or returns a pointer pointing outside
the stack, and I don't want to know -- I've simply replaced all calls to
alloca() with either PyMem_Malloc() or PyString_FromStringAndSize(NULL,)
as appropriate, followed by a size check. This addresses SF buf 851056.
Will backport to 2.3 next.
change the version number is no longer required.
Instead, a make_versioninfo.exe is compiled, which spits out an
include file for python_nt.rc.
Will backport to 2.3
- more clean up of the generated import library definiton (.DEF file)
following checking of patch 770521, and tightening of the sed regexps.
- use -O3 even with gcc 2.8.1 - worth nearly 10% with 2.3; worth
nothing with 2.2.x.
- clean up a couple of whitespace issues introduced by a cut'n'paste.
- separate the building of the core from the wrapper executables and the
external modules (.PYDs), based on the Py_BUILD_CORE define;
- clean up the generated import library definiton (.DEF file) to remove
references to a number of non-static symbols that aren't part of the
Python API and which shouldn't be exported by the core DLL;
- compile the release build with -fomit-frame-pointer, for a small
performance gain;
- make "make clean" remove byte compiled Python library files.
reorganise modules, so that most standard extensions are built into
the Python DLL. this slightly improves performance; reduces
fragmentation of address spaces and slightly reduces memory footprint.
- restructure build for modules now in Python DLL
README.os2emx
- clean out old cruft no longer appropriate now that EMX port builds
from CVS
- reflect move of modules into core DLL
- add section on building from source
PC/python_nt.rc sets up the DLL version resource (displayed when you
right-click on the DLL and select Properties).
PCbuld/python20.wse sets up the installer version resource (displayed
when you right-click on the installer .exe and select Properties). Turns
out this one hadn't been updated since 2001 <frown>!
- add new modules (zipimport, datetime, _random, bz2, _symtable)
- build pyexpat with expat sources from Python distribution
- regression test with and without compiled bytecode
- new import hooks in import.c, exposed in the sys module
- new module called 'zipimport'
- various changes to allow bootstrapping from zip files
I hope I didn't break the Windows build (or anything else for that
matter), but then again, it's been sitting on sf long enough...
Regarding the latest discussions on python-dev: zipimport sets
pkg.__path__ as specified in PEP 273, and likewise, sys.path item such as
/path/to/Archive.zip/subdir/ are supported again.
Changed the MSVC project file to create the exe in the
lib/distutils/command directory, bdist_wininst.py must still be
changed to use it.
Also changed to use the same zlib as the zlib module - this has the nice
sideeffect that now the buggy 1.1.3 version is no longer used.
Most of the source files now conform to PEP 7, except for the maximum
line length. Windows api programming in 78 character lines =:(.
README.txt is a new file, but still empty except for placeholders.
This changes sys.version under Microsoft builds to include the MS compiler
version number (_MSC_VER). Since VC 6 and VC 7 are apparently
incompatible, and both can be installed on a single box, distutils needs
some way to figure out which version of MSVC a given Python was compiled
under.
As also suggested by MvL, got rid of #ifdef'ery for the defunct _M_ALPHA
target.
Bugfix candidate? Hard to say. As far as I'm concerned, VC 7 wasn't
a supported platform in the 2.2 line. If somebody thinks it should be,
they can do the work.
CAUTION: The Python test still has many failures, but I'm out of time
for this now (already took much longer than hoped to get this far).
The base bz2 library does pass its own tests (see next).
CAUTION: People building on Windows have to download and build tne
bz2 compression libraries now. See PCbuild\readme.txt for complete
instructions.
comments everywhere that bugged me: /* Foo is inlined */ instead of
/* Inline Foo */. Somehow the "is inlined" phrase always confused me
for half a second (thinking, "No it isn't" until I added the missing
"here"). The new phrase is hopefully unambiguous.
- update DLL version number
- add files required for 2.3 (no changes to modules though)
- restructure build of pgen.exe
NOTE: As I don't have the VACPP compiler, these changes are untested.
Apart from slightly re-ordering some file lists, and matching file name
casing, I believe these changes are the minimum necessary to build 2.3
with VACPP.
- the security fixes to tempfile have lead to test_tempfile wanting
to create 100 temporary files. as the EMX default is only 40,
the number of file handles has been bumped (up to 250).
- changes to pgen have required restructuring its build support.
MSDN sample programs use it, apparently in error. The correct name
is WIN32_LEAN_AND_MEAN. After switching to the correct name, in two
cases more was needed because the code actually relied on things that
disappear when WIN32_LEAN_AND_MEAN is defined.
These built-in functions are replaced by their (now callable) type:
slice()
buffer()
and these types can also be called (but have no built-in named
function named after them)
classobj (type name used to be "class")
code
function
instance
instancemethod (type name used to be "instance method")
The module "new" has been replaced with a small backward compatibility
placeholder in Python.
A large portion of the patch simply removes the new module from
various platform-specific build recipes. The following binary Mac
project files still have references to it:
Mac/Build/PythonCore.mcp
Mac/Build/PythonStandSmall.mcp
Mac/Build/PythonStandalone.mcp
[I've tweaked the code layout and the doc strings here and there, and
added a comment to types.py about StringTypes vs. basestring. --Guido]
457466: popenx() argument mangling hangs python
226766: popen('python -c"...."') tends to hang
Fixes argument quoting in w9xpopen.exe for Windows 9x. w9xpopen.exe
also never attempts to display a MessageBox when not executed
interactively.
Added test_popen() test. This test currently just executes
"python -c ..." as a child process, and checks that the expected
arguments were all recieved correctly by the child process. This
test succeeds for me on Win9x, win2k and Linux, and I hope it does
for other popen supported platforms too :)
Removed "#undef HAVE_HYPOT" line from Borland config, as suggested.
Whether this will break some other Borland usage is a good question I
can't answer.
Curious: the MS docs say stati64 etc are supported even on Win95, but
Win95 doesn't support a filesystem that allows partitions > 2 Gb.
test_largefile: This was opening its test file in text mode. I have no
idea how that worked under Win64, but it sure needs binary mode on Win98.
BTW, on Win98 test_largefile runs quickly (under a second).
pyport.h: typedef a new Py_intptr_t type.
DELICATE ASSUMPTION: That HAVE_UINTPTR_T implies intptr_t is
available as well as uintptr_t. If that turns out not to be
true, things must get uglier (C99 wants both, so I think it's
an assumption we're *likely* to get away with).
thread_nt.h, PyThread_start_new_thread: MS _beginthread is documented
as returning unsigned long; no idea why uintptr_t was being used.
Others: Always use Py_[u]intptr_t, never [u]intptr_t directly.
SF patch #103683: Alternative dll version resources.
Changes similar to the patch. MarkH should review.
File version and Product version text strings now 2.1a2.
64-bit file and product version numbers are now
PY_MAJOR_VERSION, PY_MINOR_VERSION, messy, PYTHON_API_VERSION
where
messy = PY_MICRO_VERSION*1000 + PY_RELEASE_LEVEL*10 + PY_RELEASE_SERIAL
Updated company name to "Digital Creations 2".
Copyright now lists Guido; "C in a circle" symbol used instead of (C).
Comments added so this is less likely to get flubbed again, and
#if/#error guys added to trigger if the version number manipulations
above overflow.
Wasn't built on Windows; not in config.c either.
Module init function missing DL_EXPORT magic.
test_xreadline output file obviously wrong (started w/ "test_xrl").
test program very unclear about what was expected.
(I had explicitly disabled it a while ago, possibly unecessarily, along with
rgbimg, audioop, and imageop, which are advertised as "not for 64-bit
platforms.)
ceval.c:
define recurion_limit (static), default value is 2500
define Py_GetRecursionLimit and Py_SetRecursionLimit
raise RuntimeError if limit is exceeded
PC/config.h:
remove plat-specific definition
sysmodule.c:
add sys.(get|set)recursionlimit
This patch makes it possible to use gnu-win32 and lcc-win32
(http://www.cs.virginia.edu/~lcc-win32/) compilers to build
extension modules. It adds compiler specific sections to
PC/config.h .
It also extends the Borland compiler section. This has then two parts,
one for Win32 and the other one for the rest. The Win32 part
should be almost complete.
*** This patch is not intended to make it possible to compile
Python with these compilers, it is intended to be able to
use these compilers to build extension modules. ****
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").
There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)
Barry Scott). it appears to solve the problem on NT
and 2000, but not on Windows 95.
in other words, it's better than before, but not per-
fect. I'll leave the patch open for now.
pointed out some of the problems he had following the instructions,
and I stumbled into the others: MSVC has changed in several
respects, Python has changed the directories into which it builds
its own Windows outputs, and we grew the unusual scheme of
appending "_d" to the names of debug-mode output files.
This should all work with VC6 + CVS Python now. Some other Windows
geek please confirm! And the less you know, the better <0.5 wink>.
Explanations and examples for versions of MSVC before 6, and
versions of Python before 2.0b1, have been removed, because
they're too different and so confuse life. This last step I OK'ed
with Guido first (indeed, 'twas his idea!).
Trent Mick <trentm@activestate.com>:
Fix PC/msvcrtmodule.c and PC/winreg.c for Win64. Basically:
- sizeof(HKEY) > sizeof(long) on Win64, so use PyLong_FromVoidPtr()
instead of PyInt_FromLong() to return HKEY values on Win64
- Check for string overflow of an arbitrary registry value (I know
that ensuring that a registry value does not overflow 2**31 characters
seems ridiculous but it is *possible*).
Closes SourceForge patch #100517.
64-bit readiness (the config values are needed for patches that I will
be submitting later today. The changes are as follows:
- add SIZEOF_OFF_T #define's to PC/config.h (it was already in configure.in)
- add SIZEOF_TIME_T #define to PC/config.h and configure
Needed for some buffer overflow checking because sizeof(time_t) is
different on Win64.
- add SIZEOF_FPOS_T #define
Needed for the Win64 large file support implementation.
- add SIZEOF_HKEY in PC/config.h only
Needed for proper Win32 vs. Win64 handling in PC/winreg.c
- #define HAVE_LARGEFILE_SUPPORT for Win64
- typedef long intptr_t; for all Windows except Win64 (which defines it
itself)
This is a new ANSI (I think) type that is useful (and used by me) for
proper handling in msvcrtmodule.c and posixmodule.c
- indent the nested #ifdef's and #defines in PC/config.h
This is *so* much more readable. There cannot be a compiler
compatibilty issue here can there? Perl uses indented #defines and it
compiles with everything.
errors in some of the hash algorithms. For exmaple, in float_hash and
complex_hash a certain part of the value is not included in the hash
calculation. See Tim's, Guido's, and my discussion of this on
python-dev in May under the title "fix float_hash and complex_hash for
64-bit *nix"
(2) The hash algorithms that use pointers (e.g. func_hash, code_hash)
are universally not correct on Win64 (they assume that sizeof(long) ==
sizeof(void*))
As well, this patch significantly cleans up the hash code. It adds the
two function _Py_HashDouble and _PyHash_VoidPtr that the various
hashing routine are changed to use.
These help maintain the hash function invariant: (a==b) =>
(hash(a)==hash(b))) I have added Lib/test/test_hash.py and
Lib/test/output/test_hash to test this for some cases.
Python on UNIX now trusts PYTHONHOME unconditionally
Modules/getpath.c:
Landmark changed to os.py.
Setting PYTHONHOME now unconditionally sets sys.prefix
(and sys.exec_prefix). No further checks are done whether the
standard lib can be found in that location or not. This is in
sync with the PC subdir getpath implementations.
PC/getpathp.c:
Landmark changed to os.py.
PC/os2vacpp/getpathp.c:
Landmark changed to os.py.
Note: BAW's checkin on exceptions.c eliminates earlier concerns about
a bogus PYTHONHOME value leading to a core dump. Instead it causes a
useless sys.path and prevents imports.
Use "win32" for sys.platform on Win64 instead of "win32" because:
1. While it may be confusing to the Python scriptor on Win64 that he has to
check for win*32*, that is something that he will learn the first time. It
is better than the alternative of the scriptor happily using "win64" and
then that code not running on Win32 for no good reason.
2. The main question is: is Win64 so much more like Win32 than different from
it that the common-case general Python programmer should not ever have to
make the differentiation in his Python code. Or, at least, enough so that
such differentiation by the Python scriptor is rare enough that some other
provided mechanism is sufficient (even preferable). Currently the answer
is yes. Hopefully MS will not change this answer.
The following modules are specifically excluded in the Win64 build:
audioop, binascii, imageop, rgbimg. They are advertised as heavily 32-bit
dependent. [They should probably be fixed! --GvR]
Changes to PC\config.[hc] for Win64. MSVC defines _WINxx to differentiate the
various windows platforms. Python's MS_WINxx are keyed off of these. Note
that _WIN32 (and hence MS_WIN32 in Python) are defined on Win32 *and* on
Win64. This is for compatibility reasons. The idea is that the common case is
that code specific to Win32 will also work on Win64 rather than being
specific to Win32 (i.e. there is more the same than different in WIn32 and
Win64).
The following modules are specifically excluded in the Win64 build:
audioop, binascii, imageop, rgbimg. They are advertised as heavily 32-bit
dependent. [They should probably be fixed! --GvR]
The patch to config.h looks big but it really is not. These are the effective
changes:
- MS_WINxx are keyed off _WINxx
- SIZEOF_VOID_P is set to 8 for Win64
- COMPILER string is changed appropriately for Win64

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode. I'm also holding back on his
change to main.c, which seems unnecessary to me.)
* Base address for all extension modules updated. PC\dllbase_nt.txt
also updated. Erroneous "libpath" directory removed for all
projects.
* winsound module moved from a builtin module to an extension
module. This was done primarily to avoid Python16.dll needing to
pull in winmm.dll. Really dumb test added for winsound - but if
nothing else it ensures the module imports.
light of three different situations: (1) running from build; (2)
running from installed; (3) running without being able to find an
installation (e.g. as a COM object). The system paths in the
repository are only used for (3); the path deduced from the
installation location are used otherwise. PYTHONHOME overrides in all
cases.

running out of the build directory. This means that it will no longer
try to use an older version of the library when an older version has
been installed.
Attached is a context diff to winsound.c that adds a Beep() function
to play a sound through the PC speaker. Seems to make sense to have
this added, so I just went and did it!
