Hi,
I would like to use astgen.py to generate python classes corresponding to the
AST of something I have defined in a .asdl file, along the line of what is
apparently done for the python AST itself. I thought astgen.py would
take as an argument a .asdl file, but apparently it instead process a f
Hi devs,
the company where I work has done some work on Python, and the question
is how this work, owned by the company, can be contributed to the
community properly. Are there any license issues or other pitfalls we
need to think about? I imagine that other companies have contributed
before,

This is incorrect.
The correct information is at http://www.python.org/psf/contrib/.

Hi All,
I built the python-2.6.2 with the latest libffi-3.0.9 in AIX 5.3 using xlc
compiler.
When i try to run the ctypes test cases, two failures are seen in
test_bitfields.
*test_ints (ctypes.test.test_bitfields.C_Test) ... FAIL

A better rule would be "you may access the memory buffer in a PyString
or PyUnicode object with the GIL released as long as you own a
reference to the string object." Everything else is out of bounds (or
not worth the bother).
Is that a "yes" regarding the OP

OK, fair enough. :-)

I've been wondering whether it's possible to release the GIL in the
regex engine during matching.
I know that it needs to have the GIL during memory-management calls, but
does it for calls like Py_UNICODE_TOLOWER
Py_UNICODE_TOLOWER looks safe to me at first glance.

There is no "easy way" to do so. The only safe way is to examine all the

I don't think that's possible. The regex engine can also operate on
objects whose representation may move in memory when you don't hold
the GIL (e.g. buffers that get mutated). Even if they stay i

Why is it a problem? If we get a buffer through the new buffer API, the ob

Ok, here is another problem: SRE_OP_REPEAT uses PyObject_MALLOC,
which requires the GIL (it then also may call PyErr_NoMemory,
which also requires the GIL).

Hi,
Builtin open() function is unable to open an UTF-16/32 file starting with a
BOM if the encoding is not specified (raise an unicode error). For an UTF-8
file starting with a BOM, read()/readline() returns also the BOM whereas the
BOM should be "ignored".
See recent issues related to reading
I'm a little hesitant about this. First of all, UTF-8 + BOM is crazy
talk. And for the other two, perhaps it would make more sense to have
a separate encoding-guessing function that takes a binary stream and
returns a text stream wrapping it with the proper encoding?

I think this problem probably needs to move over to distutils-sig, as
it doesn't seem to be specific to the way that Python itself uses
distutils. distutils.command.build_ext tests for Py_ENABLE_SHARED on

That doesn't stop many applications from doing it. Python should
perhaps not produce UTF-8 + BOM without a disclaimer of
indemnification against all resulting damage, signed in blood, from
