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
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,

I'm not a license lawyer, but typically your company needs to give the

This is incorrect.

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
test_shorts (ctypes.test.test_bitfields.C_Test) ... FAIL*

A better rule would be you may access the memory buffer in a PyString

an easy way to find out?
There is no easy way to do so. The only safe way is to examine all the
functions

I've been wondering whether it's possible to release the GIL in the
regex engine during matching.
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

Yep.
Do you mean that we wouldn't need the paperwork for backporting the

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

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).

astgen.py is not used to process asdl files; ast.txt lives right
next to astgen.py. Instead, the asdl file is processed by

Yes, I know that. That's why I asked about the relation between
ast.txt and Python.adsl. If internally the parser uses the .adsl, but

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
