[issue14790] use packaging in setup.py

[Martin v . Löwis]

Martin v. Löwis  added the comment:

At the moment, it seems that this just won't happen. If a new attempt is made 
to integrate packaging with Python, this may or may not become an issue (e.g. 
whoever is doing the integration the next time might adapt setup.py from the 
beginning).

So closing this as "won't fix".

[issue15352] importlib.h should be regenerated when the marshaling code changes

[Meador Inge]

Meador Inge  added the comment:

Hmmm, I guess the idempotency issue is no worse than it already is -- the
same thing can still happen with trivial changes to the other prerequisites 
for importlib.h.

Consider this small example (you might have to run sample program multiple 
times to see a difference):

$ cat dis-closure.py
import dis

def adder(a, b):
def add():
return a + b
return add

print(dis.dis(adder(1, 2).__code__))

$  ./python.exe dis-closure.py
  5   0 LOAD_DEREF   0 (a) 
  3 LOAD_DEREF   1 (b) 
  6 BINARY_ADD   
  7 RETURN_VALUE 
None
$  ./python.exe dis-closure.py
  5   0 LOAD_DEREF   1 (a) 
  3 LOAD_DEREF   0 (b) 
  6 BINARY_ADD   
  7 RETURN_VALUE 
None

The order of 'co_cellvars', 'co_varnames', and 'co_freevars' can be
different from compile to compile, thus the bytecode can be different
from compile to compile (I am not sure if this is worth fixing).

Thus there may be times where importlib.h is regenerated, but the changes 
in the bytecode aren't significant.

I will just commit this patch as is.

[issue15233] atexit: guarantee order of execution of registered functions?

[Larry Hastings]

Larry Hastings  added the comment:

I have been meditating on this, and I'm not sure we should change 2.7.  3.2 
might be okay.

The thing is, I fear we're not just talking about CPython implementation 
details, we're talking about the Python Standard Library.  The existing 
documentation clearly gives alternative implementations free license to call 
atexit registered functions in any order they like.  So it's conceivable that 
other implementations don't guarantee reverse order.

I don't know what the right thing is to do here.  It seems like we could define 
atexit's behavior for 2.7 *if* all the major alternative implementations 
happily also implicitly guarantee reverse order.  Failing that we probably 
shouldn't touch it.  Or we could just document that reverse order is guaranteed 
in CPython only.

Of course, there are no alternative implementations that support 3.2.  That's 
why I think 3.2 might be okay.  It does seem strange to redefine part of the 
implicit language spec more than a year after the release shipped though.

[issue15342] os.path.join behavior

[Yongzhi Pan]

Yongzhi Pan  added the comment:

I suggest append "An empty last part will result in a path that ends with a 
separator" or something similar to the docstring, though it is already in the 
HTML documentation. 

Suppose someone does this like me:

In [10]: join('a', sep)
Out[10]: '/'

He must be surprised. He has to guess how to append a separator if he does not 
look at the code, or fiddle around until he finds the soultion. 

Given it explained in the docstring, after he sees:

In [10]: join('a', sep)
Out[10]: '/'

He will probably look at the docstring:

In [16]: join?
Type:   function
Base Class: 
String Form:
Namespace:  Interactive
File:   /usr/lib/python2.7/posixpath.py
Definition: join(a, *p)
Docstring:
Join two or more pathname components, inserting '/' as needed.
If any component is an absolute path, all previous path components
will be discarded. An empty last part will result in a path that
ends with a separator.

Ok, he immediately knows he has to supply an empty string instead of a 
separator.

[issue15363] Idle/tkinter ~x.py 'save as' fails. closes idle

[Roger Serwy]

Roger Serwy  added the comment:

IDLE silently closing is due to issue13582.

On Linux (Ubuntu 11.04, Tk8.5) I can not specify "~template.py" for a filename 
for opening or saving a file. Clicking on either open or save produces no 
action. However, I can specify "~/template.py".

On Win7 I see there error Terry describes. This is due to "Tilde Substitution" 
described here: http://www.tcl.tk/man/tcl/TclCmd/filename.htm#M20

Attached is a patch against 3.3 that escapes the initial tilde on Windows. The 
patch should be identical against 3.2 and 2.7.

[issue15363] Idle/tkinter ~x.py 'save as' fails. closes idle

[Terry J. Reedy]

New submission from Terry J. Reedy :

I have (had ;-) a project file ~template.py with common boilerplate.
To start a new project file, I want to open the above and save as xyz.py. I can 
edit and 'save' the template to update it just fine. But trying to do a 'save 
as' to a new name, in Idle editor, on all three current versions, I get (when 
starting Idle from command window)

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\Programs\Python33\lib\tkinter\__init__.py", line 1442, in __call__
return self.func(*args)
  File "C:\Programs\Python33\lib\idlelib\IOBinding.py", line 347, in save_as
filename = self.asksavefile()
  File "C:\Programs\Python33\lib\idlelib\IOBinding.py", line 514, in asksavefile

filename = self.savedialog.show(initialdir=dir, initialfile=base)
  File "C:\Programs\Python33\lib\tkinter\commondialog.py", line 48, in show
s = w.tk.call(self.command, *w._options(self.options))
_tkinter.TclError: user "template.py" doesn't exist

When starting Idle normally, this causes it to silently close. When run from 
the cp interpreter, the edit window blinks but continues while the trackback is 
printed in the cp window.

Just saving does not bring up a dialog; hence no problem. And I understand that 
'~' has special meaning on *nix, but I am running on Windows.

I changed '~' to '@' and the file still sorts at the top (though above 
__init__.py rather than below) and save as now works as it should. I know that 
save as worked for this file last October, but while I think it had the same 
~name then, I cannot be sure. Maybe I added '~' after the last time I 
successfully used the file.

As near as I can tell, asksavefile() passes initialfile = base = '~template.py' 
to savedialog.show which passes it unchanged and unexamined to tk.call. So the 
special casing of ~ seems to happen in tcl/tk out of our control. I am not sure 
if doing this on Windows is a tcl/tk bug or not.

For Windows, just removing '~' or even blanking the name before the .show() 
might be sensible, but maybe not for *nix.

Instead, we could catch the error instead of letting it crash Idle and put up a 
message box to the effect that one cannot 'save as' when editing a file named 
'~'. More specifically, in IOBinding.py, line 514 or so, replace

filename = self.savedialog.show(initialdir=dir, initialfile=base)

with

try:
filename = self.savedialog.show(initialdir=dir, initialfile=base)
except TclError as e:
if e.args[0].startswith('user'):
xxx display message, click ok
filename = None

I am assuming the None is the return from canceled dialogs. Certainly, None 
caused the file save code back up in saveas() (346) to skip the save.

The message could be something like "tcl/tk gives special treatment to file 
names starting with '~' and returned this error message {}".format(e.args[0])

We could also add "else: message('unanticipated tclerror prevented save as 
dialog )"

[issue15320] thread-safety issue in regrtest.main()

[Chris Jerdonek]

Chris Jerdonek  added the comment:

Thanks a lot for the feedback.  The thinking was to use a stand-alone (even 
testable) construct with dependencies made explicit.  For example, it wasn't 
obvious that the current iterator depended on forever, or whether the 
args_tuple parameter was a necessary part of it.  But I agree it should be 
simplified.

Here is a simpler patch, keeping iterator semantics.  My preference is to avoid 
adding lock semantics and additional complexity directly to main(), even though 
doing so would permit a smaller patch.

[issue15362] pyport.h includes antiquated UTF handling for FreeBSD

[John Schneider]

New submission from John Schneider :

Revision 36793 introduced a libc wrapper for FreeBSD 5.x which addressed some 
UTF issues. Unfortunately, this causes C compilation errors for certain ports.

Also reference issues 10910, 1455641

This change is no longer applicable for FreeBSD 9.  I'm not sure what version 
of FreeBSD made it not longer applicable, but there were reports of it still 
being necessary for FreebSD 7. FreeBSD 6 - 8 should be tested with this test 
script:

#!/usr/bin/env python

from ctypes import *

cdll.LoadLibrary("libc.so.7")
libc = CDLL("libc.so.7")

assert libc.isspace(0xa0) == 0


I've also attached a patch for python 2.7.3.

[issue15361] venv's Activate.ps1 causes broken prompt with powershell

[Richard Oudkerk]

New submission from Richard Oudkerk :

If I create a venv on Windows called "py3" then py3/Scripts/Activate.ps1 
defines the prompt to be

function prompt {
Write-Host -NoNewline -ForegroundColor Green [(py3) ]
_OLD_VIRTUAL_PROMPT
}

However this prompt function does not work properly, and running

Write-Host -NoNewline -ForegroundColor Green [(py3) ]

on its own produces an error because of the lack of quotes around (py3).  
Adding quotes as shown in the patch seems to fix the problem.

[issue15352] importlib.h should be regenerated when the marshaling code changes

[Meador Inge]

Meador Inge  added the comment:

Eric, that is a good point, but if someone forgets (like I did) or just hasn't 
gotten around to bumping the number yet, then the build breaks because the 
interpreter crashes.  I think we should always try to avoid building an 
interpreter that is in an inconsistent state.

Anyway, I am hitting another problem now -- _freeze_importlib is *not* 
idempotent.  Thus adding this rule might cause some noise in the builds because 
importlib.h is different when nothing has actually changed.  I am still 
investigating that problem.

Assuming I can fix the idempotency problem, then maybe _freeze_importlib should 
just be always run.

[issue14988] _elementtree: Raise ImportError when importing of pyexpat fails

[Arfrever Frehtes Taifersar Arahesis]

Arfrever Frehtes Taifersar Arahesis  added the comment:

IMHO wrong exception could be treated as a bug, which could be fixed in 3.2 and 
3.3.
Benjamin Peterson and Georg Brandl: What do you think?

> P.S. is there any way to create a test for it?

You can set sys.modules["pyexpat"]=None and test exception type when trying to 
import _elementtree.

[issue15360] Behavior of assigning to __dict__ is not documented

[Davide Rizzo]

New submission from Davide Rizzo :

The documentation (at least the obvious places, see 
Doc/reference/datamodel.rst) says classes and class instances have the 
'__dict__' attribute, but nothing is said about what happens when assigning to 
it (like obj.__dict__ = something).

As far as I understand that's undefined behavior and other implementations may 
not work the same as CPython (and CPython itself behaves differently between 
versions).

I'd submit a documentation patch if I knew how to specify this matter. Maybe 
just say the behavior is not defined?

[issue15351] Add to unittest.TestCase support for using context managers

[Michael Foord]

A method on TestCase that *just* executes the test method - allowing for 
overriding in subclasses - is an interesting idea. Including setUp and tearDown 
would be harder because TestCase necessarily does a bunch of bookkeeping

[issue15359] Sockets support for CAN_BCM

[Brian Thorne]

New submission from Brian Thorne :

In addition to CAN_RAW introduced in Python 3.3, it would be really useful to 
expose the CAN_BCM protocol. Effectively it hands off as much  to the kernel as 
possible which gives Python programs the ability to send and receive many 
periodic messages with little additional jitter or overhead.

I've attached an early stab at a patch to see if there is interest.

I'll be putting more examples of using BCM sockets at 
https://bitbucket.org/hardbyte/python-socket-examples

[issue15343] "pydoc -w " writes out page with empty "Package Contents" section

[Nick Coghlan]

Nick Coghlan  added the comment:

Fixing this has uncovered another issue: the old import emulation in PEP 302 
ignored encoding cookies, thus merrily decoding everything as utf-8 in 
"get_source()". importlib is smarter about this, which means the pydoc tests 
started failing as they tried to load the files with invalid encoding cookies.

I plan to tackle this in two parts:

- move get_source() and get_code() in importlib towards consistently raising 
ImportError, regardless of the reason the result couldn't be provided (chaining 
the exceptions to ensure details aren't lost)

- update pydoc to tolerate ImportError from get_source.

New submission from Nick Coghlan :

Created to record the egregious hack of relying on the test_runpy

It gets the job done, but is a really messy way of going about it. Worth 
cleaning up by factoring the support code out to a helper module when there 
isn't a release deadline looming.

[issue15272] pkgutil.find_loader accepts invalid module names

[Nick Coghlan]

Nick Coghlan  added the comment:

OK, this one is trickier than I thought - the exact behaviour depends on how 
you traverse the code, and I believe a PEP 302 importer is technically allowed 
to accept "/" in module names. (Unless there's a module names "must be valid 
identifiers" in there somewhere that I have forgotten about)

Punting on it for the moment.

[issue1767933] Badly formed XML using etree and utf-16

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Thank you, Eli.

However changes to tostring() and tostringlist() break the invariant 
b"".join(tostringlist(element, 'utf-16')) == tostring(element, 'utf-16'). You 
should add followed methods to DataStream:

def seekable(self):
return True

def tell(self):
return len(data)

Note, that monkey-patched version is faster.

stream = io.BufferedIOBase()
stream.writable = lambda: True
stream.write = data.append
stream.seekable = lambda: True
stream.tell = data.__len__

Benchmark results:
