[issue8107] test_distutils fails on Windows in 2.6.5rc2

[Martin v . Löwis]

New submission from Martin v. Löwis :

test_distutils fails like this:

test test_distutils crashed -- : object of type 
'NoneType' has no len()
Traceback (most recent call last):

Not sure whether this is a regression from 2.6.4.

[issue8107] test_distutils fails on Windows in 2.6.5rc2

[Ezio Melotti]

Ezio Melotti  added the comment:

This has been introduced in r77955, and affected all the 2.6 Windows buildbots 
(e.g. 
http://www.python.org/dev/buildbot/builders/x86%20XP-5%202.6/builds/9/steps/test/logs/stdio).
The problem is caused by the fact that "srcdir = 
sysconfig.get_config_var('srcdir')" returns None on Windows.

[issue7540] urllib2 request does not update content length after new add_data

[Fred L. Drake, Jr.]

Fred L. Drake, Jr.  added the comment:

The reverts in SVN look good to me; re-closing this issue as no further action 
is required.

If there's a proposal for specific changes to urllib2 to improve diagnostics in 
unsupported cases, that should be detailed in a separate issue.

Marking this issue "invalid" since the original reported symptom was determined 
to be caused by an unsupported use (re-use of the request).

SSL sockets should support SNI, both as servers and clients:

After that, libraries that support SSL/TLS should be upgraded to take advantage

[issue8110] subprocess.py doesn't correctly detect Windows machines

[Dave Fugate]

New submission from Dave Fugate :

subprocess.py contains the following line (380 in CPython 2.6.3):
mswindows = (sys.platform == "win32")

which only correctly detects CPython on Windows.  This line should be changed 
to:
mswindows = (sys.platform == "win32" or sys.platform == "cli" or 
sys.platform == "silverlight")

so subprocess can be utilized from IronPython as well.

This bug should be trivial to fix.

[Brian Curtin]

Brian Curtin  added the comment:

Amaury is right. On Windows, _subprocess is a built-in, so the platform stuff 
just currently enables further failure.

Dave: My C# skills aren't the greatest, but looking at PC/_subprocess.c there 
are a few Win32 functions you might need to P/Invoke, but I believe a lot of 
the functionality is supported in .NET.

Does the reassignment only apply to the more recent more ambitious patch?  The

[issue1222585] C++ compilation support for distutils

[Tarek Ziadé]

Tarek Ziadé  added the comment:

If we consider that Distutils didn't provide c++ support, and that it partially 
worked by accident (through gcc), I would call it a new feature. Especially 
since it requires a new option.

We are freezing the API so we can't add options to methods/functions. 

That's why it could be done on distutils2 instead, which will be released when 
2.7 final is released (but not in the stdlib), and backward compatible with 
2.4, 2.5, 2.6.

If we could do the proper job for C++ support in distutils2 that would be 
better. 

Notice that distutils2 is a fork of how distutils was in trunk last month, so 
it should be fairly simple to depend on it in your project, to benefit from new 
features etc. The goal is to push it back in the stdlib in 3.3. 

If you want to start a dev. branch of your project using distutils2, I am 
willing to help there.

[issue8113] PyUnicode_AsUnicode doesn't check for NULL pointer

[Lorenz Quack]

New submission from Lorenz Quack :

The C-API function "PyUnicode_AsUnicode(PyObject *unicode)" does not check the 
argument for NULL pointers. 
It passes it directly to the macro "PyUnicode_Check(op)" which then crashes 
when trying to access "Py_TYPE(op)".

I marked this as Python 2.7 because I checked this on trunk but I assume that 
this bug is present in all versions.

The attached patch fixes this issue.

[issue8107] test_distutils fails on Windows in 2.6.5rc2

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

Um, this sucks because I think that that means it was introduced after 2.6.4 
final.  Since it's a regression, marking as a blocker for 2.6.5 final, but in 
order to stay a blocker it has to be a really critical bug and I'll want to 
review the fix before it goes it (to make sure it doesn't break anything else). 
 Otherwise, I'll bump it down to deferred blocker and we can fix it for 2.6.6.

[issue8107] test_distutils fails on Windows in 2.6.5rc2

[Tarek Ziadé]

Tarek Ziadé  added the comment:

This test just grabs xxmodule.c from Python to try out a compilation.

It's a lot of work just to try out a .c file in build_ext. I've already changed 
this in trunk by having a c file local to distutils tests, as a fallback in 
case the location cannot be found (depending on the execution context).

I can backport this to 2.6. It's pretty safe to do it since its just a change 
in the test, the distutils code is not changed. Barry let me know if you want 
me to do backport it in release26, and if yes, when I should do it.

[issue8107] test_distutils fails on Windows in 2.6.5rc2

[Ned Deily]

Ned Deily  added the comment:

I'm guessing this falls into the same category as Issue8102, that is, since the 
python tests are also installed and run on end-user systems by various 
installers, it is important that none of the tests depend on files from a 
python build directory or source tree.  In other words, if a test needs a file, 
that file needs to be explicitly installed.

[issue7774] sys.executable: wrong location if zeroth command argument is modified.

[STINNER Victor]

STINNER Victor  added the comment:

"Thanks to" my commit r78826 (fixing #3137), site errors are now fatal: Python 
exits with an error instead of just printing "import site failed; ...". It's 
the come back of #7774: test_executable_with_cwd of test_subprocess now always 
fail.

The test fails because of an error raise by the site module:
-

[issue8113] PyUnicode_AsUnicode doesn't check for NULL pointer

[Lorenz Quack]

Lorenz Quack  added the comment:

I thought that the CamelCase C-functions like PyUnicode_AsUnicode would check 
for errors like this and if you don't want error checking you can use the 
capitalized versions like PyUnicode_AS_UNICODE.
I just looked at the code for PyFloat_AsDouble and it checks for NULL pointers. 
so does PyInt_AsLong. 
OTOH, PyString_As does not.
I didn't check on any other types.

So if it is not considered a bug then I just want to point out the 
inconsistency.

IMHO, the C-API documentation lacks information on how it behaves in error 
conditions (this might be a bit over generalized). Would there be interest in 
documentation patches in these cases or are developers expected to look at the 
actual source code for this kind of information?

[issue8113] PyUnicode_AsUnicode doesn't check for NULL pointer

[STINNER Victor]

STINNER Victor  added the comment:

> I just looked at the code for PyFloat_AsDouble and it checks for NULL pointers

It's just a little help for developers: it will raise the ugly TypeError("bad 
argument type for built-in operation") and returns -1.

It's never a good idea to pass NULL to a function of the Python C API. I think 
that most (or all?) functions will fail.

> IMHO, the C-API documentation lacks information on how it behaves 
> in error conditions (this might be a bit over generalized).

I didn't read the documentation, but you HAVE TO always check the result of a 
Python function.

If the function returns a PyObject*, you have to check that the result is not 
NULL. The same rule applies for Pyxxx_AsXxx(): you also have to check the 
result (the error value depends on the function). Eg. PyInt_AsLong() returns -1 
on error: use (result == -1) && PyErr_Occured()) in the caller to detect an 
error.

[issue8107] test_distutils fails on Windows in 2.6.5rc2

[Barry A. Warsaw]

Barry A. Warsaw  added the comment:

Tarek, I guess the fix is as haypo suggests?  Just use sysconfig.project_base 
if sysconfig.get_config_var('srcdir') returns None?

If that's the only change, then please do fix this for 2.6.5 final.  Thanks!

[issue7774] sys.executable: wrong location if zeroth command argument is modified.

[STINNER Victor]

STINNER Victor  added the comment:

This issue is not related to subprocess, subprocess is just used in examples to 
show the bug. The problem is that Python defines an invalid sys.executable if 
the process was created with a custom argv[0]. In Python trunk, the site module 
now uses sysconfig which depends on sys.executable. If sys.executable, 
sysconfig fails, site import fails, and finally Python exists (since my fix for 
#3137). I think that we have to split the problem in two parts:

 1) Python startup fails if sysconfig raises an error
 2) sys.executable is invalid is argv[0] is modified

(1) Functions using (indirectly) sysconfig in site module:

 - addbuilddir()
 - addusersitepackages()

I don't know if Python should exits with an error if these functions fail.

(2) Except of Python unit test, is it required in "real world" applications? I 
know that Twisted does modify argv[0] to display "twistd" in process list. It 
looks like there is trivial, portable and/or reliable solution for this problem.

[issue7774] sys.executable: wrong location if zeroth command argument is modified.

[STINNER Victor]

STINNER Victor  added the comment:

Twisted uses the following code (on UNIX-like OS):

def launchWithName(name):
if name and name != sys.argv[0]:
exe = os.path.realpath(sys.executable)
log.msg('Changing process name to ' + name)
os.execv(exe, [name, sys.argv[0], '--originalname'] + sys.argv[1:])

Twisted doesn't care if sys.executable is invalid when argv[0] has been 
changed. sys.executable is only used to change the process name (sys.executable 
is used before argv[0] is modified).

[issue7774] sys.executable: wrong location if zeroth command argument is modified.

[Florent Xicluna]

Florent Xicluna  added the comment:

Actually there's 3 steps to fix this:
1) do not absolutize the sys.executable if it is empty (in Modules/getpath.c)
2) change sysconfig.py to deal with empty sys.executable (see this patch)
3) do a best effort to provide a valid sys.executable.
   It should be possible in most cases.

See message above for details on (3):
http://bugs.python.org/issue7774#msg98284

Patch attached for (2). (Fixes tests)

[issue7424] segmentation fault in listextend during install

[Jon Buller]

Jon Buller  added the comment:

Sorry to not be able to follow up for so long, but I was moving 
cross-country.

I was playing with the tests a bit and ended up trying this:

$ ./python -E -tt -d -v -W all ./Lib/test/regrtest.py -l -v -s test_builtin

Which resulted (after quite a bit of output) in this:

# /usr/pkgsrc/lang/python26/work/Python-2.6.4/Lib/tempfile.pyc matches 
/usr/pkgsrc/lang/python26/work/Python-2.6.4/Lib/tempfile.py
import tempfile # precompiled from 
/usr/pkgsrc/lang/python26/work/Python-2.6.4/Lib/tempfile.pyc
dlopen("/usr/pkgsrc/lang/python26/work/Python-2.6.4/build/lib.netbsd-5.99.24-sparc-2.6/fcntl.so",
 
2);
import fcntl # dynamically loaded from 
/usr/pkgsrc/lang/python26/work/Python-2.6.4/build/lib.netbsd-5.99.24-sparc-2.6/fcntl.so
import thread # builtin
test_builtin
[1]   Segmentation fault  ./python -E -tt -d -v -W all 
./Lib/test/regrtest.py -l -v -s test_builtin

So, is this perhaps a bug either in Python's thread usage, or NetBSD's 
thread
library?  Is there an easy way to tell python to build without any threads,
even if configure finds the proper system include files and libraries?  Is
it as simple as "./configure --without-threads" when starting the build?
(I'm about to try that...)

[issue8107] test_distutils fails on Windows in 2.6.5rc2

[Tarek Ziadé]

Tarek Ziadé  added the comment:

No that won't work because the test tries to find a module that is only in the 
source dir. So not existing on python installations. The simplest thing to do 
is to skip the test if srcdir cannot be found. 

I'll fix this asap

Tarek Ziadé  added the comment:

Also, notice that srcdir can be broken on some platform. For instance, under 
Mac OS X Framework install:

>>> import distutils.sysconfig
>>> distutils.sysconfig.get_config_var('srcdir')
'/Volumes/Rivendell/Users/ronald/Projects/python/r264'

we get the path that was used by Ronald to compile the distribution :)

Working on it..

[Ned Deily]

Ned Deily  added the comment:

It's not that "srcdir" is broken - that undoubtedly was the value of the source 
directory on the *build* machine.  The problem is that "srcdir", (and likely 
some other build related config variables) has no meaning other than on the 
*build* machine at the time of the build.  It (they) cannot in general be 
meaningfully used at execution time, particularly if the install takes place on 
a machine other than build machine.

[issue8115] Pyojbc on Snow Leopard

[Ronald Oussoren]

Ronald Oussoren  added the comment:

This issue is off-topic for the python bugtracker.

But: to install pyobjc you need to do three things:

1) Download and install easy_install or distribute 
   (download from pypi.python.org)

2) Check that 'which easy_install' refers to a 
   file inside /Library/Frameworks/Python.framework

3) Run easy_install pyobjc==2.2

If that doesn't work: subscribe to the list at 
 and ask there.

[issue8107] test_distutils fails on Windows in 2.6.5rc2

[Ronald Oussoren]

Ronald Oussoren  added the comment:

IMHO stuffing xxmodule.c inside the distutils test tree (see msg100815) is the 
right solution because the python source tree might not be present during 
testing (such as when the user does a binary install and then runs the 
unittests to check if everything works).

Tarek: sysconfig.get_config_var('srcdir') returns the value of 'srcdir' in  
'Makefile' and that value is only valid during the build of Python. It is the 
variable that is used in Python's makefiles to refer to files in the source 
tree and is needed when you run configure from a directory that is not the root 
of the source tree.

This doesn't fail on OSX when using a framework build of Python because that
