[issue19610] Give clear error messages for invalid types used for setup.py params (e.g. tuple for classifiers)

2015-04-08 Thread Berker Peksag

Berker Peksag added the comment:

Thanks for the review, Éric. New patch attached.

 When running a setup.py that uses a tuple for classifiers, is the error 
 message in the terminal user-friendly, or do we get a full traceback?

A full traceback:

Traceback (most recent call last):
  File setup.py, line 37, in module

[issue23857] Make default HTTPS certificate verification setting configurable via global ini file

2015-04-08 Thread Nick Coghlan

Nick Coghlan added the comment:

I like the idea of a separate 2.7-redistributor branch to capture changes 
like this, as that would almost *exactly* duplicate the kernel maintenance 
model.

That approach would also mean that we don't have to figure out sensible 
upstream documentation for features like this that only make sense in the 
context of a redistributor that is responsible for ensuring they're used 
appropriately.

Milap: I think changes like you mentioned (originally by me) would be fine. 
Another variation was done for Issue 10838: revision 10b0a8076be8, which 
expects each object that is not a module object (e.g. not from “import sys”), 
rather than expecting each object that is a function or class defined in the 
module. It might depend on the particular circumstance which technique is 
superior.

[issue23886] faulthandler_user should use _PyThreadState_Current

SIGUSR1/2 will get delivered to any running thread. The current thread of the

thread which holds the GIL instead, or use NULL.

[issue23865] Fix possible leaks in close methods

2015-04-08 Thread Serhiy Storchaka

Serhiy Storchaka added the comment:

Ah, yet one purpose of the patch is to make close() methods more robust when 
called at shutdown. Objects can be partially deconstructed at that time, 
attributes can be set to None to break reference loops. That is why I use None 
as signaling value and always check some attribute for None.

The changes to aifc make sense. close() is called from __exit__(). When context 
manager is used in a generator, it creates a reference loop. So self.file is 
None in this case and self.file.close() will raise an AttributeError.

[issue23882] unittest discovery and namespaced packages

2015-04-08 Thread Alex Shkop

Alex Shkop added the comment:

Spent some time looking into this one. Looks like the problem is in 
TestLoader.discover() method. There are couple of issues I found in it, all 
caused by same assumption.

Documentation [1] states that all test modules found by discover() method 
should be importable from top_level_dir. Whenever this method finds a 
subdirectory of start_dir it checks for __init__.py file. If there's no 
__init__.py then finder assumes that files within this package is not 
importable and stops recursion. This kind of 'importablity' check is not valid 
since we have namespace packages.

I'm not sure what should be done to fix this issue. We can change documentation 
to state that only regular packages with tests will be discovered. Or we can 
fix 'importability' checks, which will mean that all tests in all 
subdirectories will be discovered.

[issue23887] HTTPError doesn't have a good repr representation

2015-04-08 Thread Facundo Batista

New submission from Facundo Batista:

I normally print(repr()) the exception I got, for debugging purposes. I use 
repr() because for builtin exceptions, str() will print only the message, and 
not the exception type.

But for HTTPError, the repr() of it is HTTPError(), without further 
explanation...

[issue23889] Speedup inspect.Signature.bind

2015-04-08 Thread Yury Selivanov

New submission from Yury Selivanov:

Right now the implementation of Signature.bind is very complex, which leads to 
a subpar performance. The only way to significantly speed it up is to employ 
code generation and cache (the other way it to rewrite it in C, but that's 
something I'd like to avoid). I'll upload an initial implementation soon.

[issue23888] Fixing fractional expiry time bug in cookiejar

2015-04-08 Thread ssh

New submission from ssh:

If the FileCookieJar reads a cookie whose expiry time is a decimal fraction, it 
crashes.

Chrome extensions cookies.txt and EdiThisCookie export the expiry time as 
decimal fractions. This is accepted by wget and curl, but not by the 
FileCookieJar which ends up crashing.

I made a StackOverflow question checking if fractional decimal expiry times 
were even allowed (if it was a bug in the extensions), but didn't get a 
response: 
https://stackoverflow.com/questions/29502672/can-the-cookie-expires-field-be-a-decimal-value

At any rate, this patch should make the library more robust.

Jeff McNeil added the comment:

So, yeah, that's right. In the attached patch, I'm closing the file descriptor 
if the timeout/error happens on a non-blocking call.  It fails with an EBADF on 
reconnect at that point, but it doesn't potentially leave an FD in the proc's 
file table.

Should be no more EINTR's coming out of the select call.

[issue23891] Tutorial doesn't mention either pip or virtualenv

2015-04-08 Thread A.M. Kuchling

New submission from A.M. Kuchling:

(from discussion at the 2015 Python Language Summit)

Current versions of Python make it relatively easy to install third-party 
packages such as requests.  New users may not realize this, though, and 
continue using libraries such as urllib/urllib2 because they're in the stdlib.

The Python tutorial doesn't seem to mention either virtualenv or pip. It 
should, describing how to create a virtualenv, install packages, and manage 
them in basic ways (removing, 'pip freeze', requirements.txt.)

[issue15443] datetime module has no support for nanoseconds

2015-04-08 Thread Alexander Belopolsky

Alexander Belopolsky added the comment:

Python 2 line is closed for new features, but you can start with the main line 
Lib/datetime.py which will probably work with python 2.7.9 after some minor 
tweaks.  You should be able to publish the result on PyPI.  Note that many new 
in 3.x modules are provided for 2.x this way.

2015-04-08 Thread Steve

Steve added the comment:

Although I don't know what I am doing (patching python), if someone could point 
me to the relevant files in 2.7.9 that need to be patched, I'm willing to see 
if I can do it.

[issue15443] datetime module has no support for nanoseconds

2015-04-08 Thread mdcb

mdcb added the comment:

Alexander,

The initial patch is indeed minimal. If it gains momentum and some level of 
acceptation, I'd be happy to do more amends and fixes as needed and recommended.

As for 2.7.9 - I'm not sure it makes much sense going PyPI patch if it's not 
going to happen on 3.x?

[issue23893] Forward-port future_builtins

2015-04-08 Thread Brett Cannon

New submission from Brett Cannon:

future_builtins exists in Python 2.7, but not Python 3 which is annoying for 
code that wants to rely on it in Python 2.7 but not 2to3 (who is the primary 
user of the module for rewrite rules).

[issue15443] datetime module has no support for nanoseconds

2015-04-08 Thread Alexander Belopolsky

Alexander Belopolsky added the comment:

I have no doubt this will get into 3.x once we have a working patch and 
backward compatibility issues are addressed.  Given the amount of effort Victor 
has recently put in #22117 to rework CPython internal time handling to support 
nanoseconds, it will be odd not to support nanoseconds in datetime.

On the substance, in your patch you have chosen to add nanoseconds as a 
separate field instead of changing microseconds to nanoseconds.  I don't think 
this is the right approach.  See msg223082.  Once you get to implementing 
timedelta arithmetics, you will see that carrying two subsecond fields will 
unnecessarily complicate the code.

[issue9517] Make test.script_helper more comprehensive, and use it in the test suite

2015-04-08 Thread R. David Murray

R. David Murray added the comment:

Script helpers has been made more discoverable by moving it into the 
test.support namespace, but it has not been documented in the test.support 
docs.  I can no longer remember if this is intentional or not.  Regardless, 
this issue is still valid insofar as there are probably a number of places in 
the test suite where script_helpers can be used that they aren't being used.  
We probably don't want a multi-module changeset, though, so this could become a 
meta issue for new issues for converting particular test files to use 
script_helpers.

[issue19561] request to reopen Issue837046 - pyport.h redeclares gethostname() if SOLARIS is defined

2015-04-08 Thread John Beck

John Beck added the comment:

We (Solaris engineering) have hit this issue after migrating from 2.6
being our default version of Python to 2.7 being the default.  The
specific component that broke was vim (version 7.4), trying to compile
if_python.c:

/usr/include/python2.7/pyport.h, line 645: identifier redeclared:
gethostname 
 
current : function(pointer to char, int) returning int  
 
previous: function(pointer to char, unsigned long) returning int :  
 
/usr/include/unistd.h, line 412   
 

We had this patched out in Python 2.6's Include/pyport.h:

-#ifdef SOLARIS
-/* Unchecked */
-extern int gethostname(char *, int);
-#endif

but for some reason that patch was not propagated to our 2.7 line.
Until today, that is; I will be applying that patch shortly to both
2.7 and 3.4.

[issue21411] Enable Treat Warning as Error on 32-bit Windows

2015-04-08 Thread Zachary Ware

Zachary Ware added the comment:

This has been complicated by the migration to VS2015, which added a bunch of 
new warnings.  Obviously we can't enable this now without either fixing all the 
warnings (unlikely, I think; most of them are just about shadowing vars) or 
disabling particular ones.

So at this point, fix, disable, or reject?

[issue23865] Fix possible leaks in close methods

2015-04-08 Thread Martin Panter

Martin Panter added the comment:

Okay, I think I get it. You are setting some attributes to None, in case they 
happen to be causing a reference cycle. When close() is called, they are no 
longer needed, so it might help to breaking potential reference cycles. I have 
often wondered why this was done. I always assumed it was a carry-over from old 
code relying on the garbage collector to automatically close files, etc.

[issue15443] datetime module has no support for nanoseconds

2015-04-08 Thread Alexander Belopolsky

Alexander Belopolsky added the comment:

Matthieu,

I don't see you adding nanoseconds to timedelta in your patch.  Doesn't this 
mean that you would loose nanoseconds when you subtract one datetime from 
another?

To anyone who wants to contribute to this effort, I would recommend starting 
with pure python implementation in Lib/datetime.py .

[issue23890] assertRaises increases reference counter

2015-04-08 Thread R. David Murray

R. David Murray added the comment:

This is presumably a result of the exception object being saved on the context 
manager object and there being a circular reference chain that doesn't 
immediately get GCed.  This is just how python works.

I don't know if it would be sensible/useful to use the new lightweight 
traceback stuff in assertRaises.  If so it would probably have to be optional 
for backward compatibility reasons.

[issue8027] distutils fail to determine c++ linker with unixcompiler if using ccache

2015-04-08 Thread Joshua J Cogliati

Joshua J Cogliati added the comment:

I looked and the autoconf variable for the c++ linker is CXXLINK, so I think 
the proper way to fix this would be to change sysconfig.py to look at both 
CXXFLAGS and CXXLINK, and create those and use it to define a cxxlink variable, 
and only if they are missing should we actually try to do some of the magic 
that is currently used.

Also, my patches (fix-distutils-*.patch) do not always work, because sometimes 
the c compiler cannot link the c++ code.

2015-04-08 Thread Ned Deily

Ned Deily added the comment:

Russell, we talked a bit about this topic at the Python Language Summit today 
(after watching your excellent video).  I think there was general agreement 
there that having iOS support would be a good thing along with the 
recognition that the requirements for support of a mobile platform like iOS 
differ in some significant ways from most traditional platforms that Python has 
supported.  I agreed to shepherd this issue.  I have some initial thoughts but 
will write up something more detailed shortly.

[issue23713] intermittent failure of multiprocessing unit test test_imap_unordered_handle_iterable_exception

2015-04-08 Thread Davin Potts

Davin Potts added the comment:

Serhiy: If I understand correctly what you suggest, calling sorted(it) or 
list(it) would run the iterator all the way until it raises the SayWhenError 
exception, triggering the self.assertRaises before it ever actually gets to 
call the self.assertEqual or self.assertCountEqual you suggest.  It would 
indeed test the raising of the exception but would never test individual values 
returned by the iterator to see that they belong.

Or were you suggesting something different?
