[issue6700] inspect.getsource() returns incorrect source lines

[Gabriel Genellina]

New submission from Gabriel Genellina :

inspect.getsource(obj) returns incorrect results when obj is a 
traceback or frame object outside any function (that is, at the module 
level).

This demo script shows the problem. The correct output should contain 
all source lines in the module, but it only returns the first two:


D:\temp>type show_inspect_bug.py
def foo(x):
  return y + z

import inspect
frame = inspect.currentframe()
print inspect.getsource(frame)


D:\temp>python show_inspect_bug.py
def foo(x):
  return y + z


The attached patch fixes the problem and adds some missing test cases.
Originally reported by Juanjo Conti at the local Python group.

[issue6681] email.parser clips trailing \n of multipart/mixed part if part ends in \r\n

[R. David Murray]

R. David Murray  added the comment:

Looks like it is a regular expression issue.  The code is trying to
delete the last linend before the boundary, which belongs to the
boundary according to the RFC, but it does so with the following RE:

(\r\n|\r|\n)$

This RE matches '\r\n' in '\r\n\n', which is what Guido's message had. 
The code then deletes the number of characters equal to the length of
the match.  So yes, it is a mixed line ending problem.

[issue6698] IDLE no longer opens only an edit window when configured to do so

[Guilherme Polo]

New submission from Guilherme Polo :

If someone configure IDLE to start a edit window by default, I believe
it should open only an edit window without starting shell window. This
has been the behaviour in previous version, but it is acting different now.

I looked into r71126 and I think this behaviour was changed there
unintentionally. Its log message doesn't seem to mention this change,
that is why I'm thinking this.

[issue1628205] socket.readline() interface doesn't handle EINTR properly

[Gregory P. Smith]

Gregory P. Smith  added the comment:

fixed in trunk r74426.  socket.socket.sendall() and all
socket._fileobject methods (read/readline/write/flush) now properly
handle EINTR internally.

sendall will allow a python signal handler to raise an exception
aborting it in unknown state, otherwise it handles EINTR as it should
and continues sending.

I'm leaving this issue open until it is merged into py3k and considered
for 2.6 and/or 3.1 release backporting.

[issue6695] PyXXX_ClearFreeList for dict, set, and list

[Skip Montanaro]

Skip Montanaro  added the comment:

Instead of expanding the C API for each type which supports a free
list perhaps there should be a single call, say, PyObject_ClearFreeList,
which takes a pointer to the appropriate type object as an argument.
PyTypeObject can then grow a tp_free_list slot through which the
function calls a type-specific free list clearing function.

[issue3392] subprocess fails in select when descriptors are large

[Martin v . Löwis]

Martin v. Löwis  added the comment:

Unfortunately, this change has broken windows support of the subprocess
module, which now reports, on "import subprocess".

>>> import subprocess
Traceback (most recent call last):
  File "", line 1, in 
  File "C:\loewis\31\python\lib\subprocess.py", line 390, in 
_PIPE_BUF = getattr(select, 'PIPE_BUF', 512)
NameError: name 'select' is not defined

As a consequence, even building Python on Windows now fails, so setting
the priority to "release blocker". One solution would be to move the
"import select" to being top-level.

[issue6696] Profile objects should be documented

[Alexander Myodov]

New submission from Alexander Myodov :

Seems like a minor documentation issue in 2.x became more significant 
one in 3.x.

In Python 2.6 (and lower), the documentation on Profile objects 
discussed them as a part of hotshot module, while omitting the fact 
that any profiler module, either of profile/cProfile/hotshot, supports 
them (though in fact, hotshot Profile objects have an api a bit 
different from profile/cProfile Profile objects). Note http://
docs.python.org/2.6/library/hotshot.html#profile-objects - there is no 
separate documentation of non-hotshot Profile objects, though they are 
largely similar. This is a minor issue which could probably be fixed in 
2.7 as a separate problem - otherwise it is pretty unclear from the 
documentation, what methods do cProfile Profile objects support (eg, 
they support enable()/disable() and runcall() methods, which is pretty 
useful for profiling, but impossible to find in documentation).

In Python 3.1, looks like everything related to hotshot was removed 
from the documents, including the documentation on Profile objects - 
which should not have been. This means, that now the documentation on 
profilers does not cover any Profile classes at all - see http://
docs.python.org/3.1/library/profile.html . For example, the official 
documentation doesn't say any way to profile a function passing 
arguments to it and receiving its result - while profile/cProfile 
Profile objects still do support runcall() method.

[issue6695] PyXXX_ClearFreeList for dict, set, and list

[Matthias Troffaes]

New submission from Matthias Troffaes :

The Python C API provides PyXXX_ClearFreeList functions to allow the
float, int, etc... freelists to be freed, potentially releasing memory
to the OS earlier. Currently, there is no such API for the dict, set,
and list freelists.

The attached patch adds PyXXX_ClearFreeList functions to the C API, so
the dict, set, and list freelists can be freed as well.
