[issue5950] Make zimport work with zipfile containing comments

[Dmitry]

Dmitry  added the comment:

I'm talking about internal zimport function (see attached testcase): 

i.e.

import sys;
sys.path.insert(0,'test.zip');

import test
test.testme()

doesn't work if test.zip contains comment.

Right, but you still have to check whether wchar_t is usable, don't
you ? If wchar_t is 2 bytes on a non-Windows platform, using the
wctypes functions won't work either.

The line should probably read:

#if defined(WANT_WCTYPE_FUNCTIONS) && defined(HAVE_USABLE_WCHAR_T) && 
defined(Py_UNICODE_WIDE)

True.

The support for the wctype functions should have been remove long ago,
since they cause subtle incompatibilities between Python builds. I should
have probably never added it in the first place... people were worried
about the size of the type record tables at the time, which is why
I thought it would be a good idea to try to optionally use the C lib
functions.

The comment was true before the Python type tables were changed
into a type record database: the switch used to remove the
Python tables required for those functions. With the type records
database, this is no longer the case, since the records are also
being used for properties that are not exposed via wctype functions.

I'd suggest to close the ticket.

The main idea behind version 0 was to have a readable format. The
occasional UTF-8 in the stream should be readable enough nowadays,
even if it's not ASCII.

At least visually, there don't appear to be any differences between
v4 and v5 of the patch.

I'd be fine with enabling the switch on those platforms as well,
if we could get feedback from someone testing the behavior of gcc
on an AMD platform running Ubuntu 10.4.

If the problem is really only with the code snippet listed in the
bug report, there shouldn't be a problem and we can go ahead with
enabling computed gotos on that platform/compiler combination as well.

If R Oudkerk signed the agreement, replacing 'see COPYING.txt' with

Does the PSF have the agreement?

[issue9211] Cannot close socket after ssl handshake failed

[Christian Hager]

New submission from Christian Hager :

When running a SSL socket server in Python 2.5 or 2.6 (didn't try with newer 
versions), new connections are setup with "ssl.wrap_socket()". Everything works 
fine if I connect a client with SSL, but if I just telnet to the server it's 
not possible to close the socket anymore (receiving data works fine through the 
non-ssl socket though).

I get a SSL exception like this: "SSLError: [Errno 1] _ssl.c:480: 
error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol". After 
that I am not able to close the socket, but still can send data on the 
non-ssl-wrapped socket. How would I close this now open non-ssl socket?

Simplified code:

read_sockets,write_sockets,error_sockets = select.select(CONNECTION_LIST,[],[])
for sock in read_sockets:
if sock == server_socket:
newsock, addr = server_socket.accept()

# SSL Setup
try:
sslsock = ssl.wrap_socket(newsock, server_side=True, 
certfile="../cert.pem", keyfile="../cert.pem")
CONNECTION_LIST.append(sslsock)
except:
print "ssl handshake failed"

try: 
newsock.send("bye\r\n") # succeeds
newsock.close() # doesn't work

Indeed. I would also remove "pythonic", because it will only confuse the

[issue2009] Grammar change to prevent shift/reduce problem with varargslist

[Mark Dickinson]

Mark Dickinson  added the comment:

+!. I had to do a very similar refactoring recently when trying to fix the 
parser module to understand keyword-only arguments and annotations.

Taking keyword-only arguments into account, I think the replacement needs to be:

varargslist: (vfpdef ['=' test] (',' vfpdef ['=' test])* [',' 
   ['*' [vfpdef] (',' vfpdef ['=' test])* [',' '**' vfpdef] | '**' vfpdef]]
 |  '*' [vfpdef] (',' vfpdef ['=' test])* [',' '**' vfpdef] | '**' vfpdef)

and the analogous replacement needs to be made in the production for 
'typedargslist', too.

BTW, I'm a bit surprised that the grammar doesn't allow for trailing commas 
after keyword-only arguments:  that is,

def f(a, b,): ... is fine, but
def f(*, a, b,): ...  is a SyntaxError

[issue9198] Should repr() print unicode characters outside the BMP?

[Ezio Melotti]

Ezio Melotti  added the comment:

Here is a patch to "fix" sys_displayhook (note: the patch is just a proof of 
concept -- it seems to work fine but I still have to clean it up, add comments, 
rename and reorganize some vars and add tests).
This is an example output while using iso-8859-1 as IO encoding:

w...@linuxvm:~/dev/py3k$ PYTHONIOENCODING=iso-8859-1 ./python
Python 3.2a0 (py3k:82643:82644M, Jul  9 2010, 11:39:25)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys; sys.stdout.encoding, sys.stdin.encoding
('iso-8859-1', 'iso-8859-1')
>>> 'ascii string'
'ascii string'  # works fine
>>> 'some accented chars: öäå'
'some accented chars: öäå'  # works fine - these chars are encodable
>>> 'a snowman: \u2603'
'a snowman: \u2603'  # non-encodable - the char is escaped instead of raising 
an error
>>> 'snowman: \u2603, and accented öäå'
'snowman: \u2603, and accented öäå' # only non-encodable chars are escaped
>>> # the behavior of print is still the same:
>>> print('some accented chars: öäå') 
some accented chars: öäå
>>> print('a snowman: \u2603')
Traceback (most recent call last):
  File "", line 1, in 
UnicodeEncodeError: 'latin-1' codec can't encode character '\u2603' in position 
11: ordinal not in range(256)

-

While testing the patch with PYTHONIOENCODING=iso-8859-1 I also found this 
weird issue that however is *not* related to the patch, since I managed to 
reproduce on a clean py3k using PYTHONIOENCODING=iso-8859-1:
>>> 'òàùèì  óáúéí  öäüëï'
'ò�\xa0ùèì  óáúé�\xad  öäüëï'
>>> 'òàùèì  óáúéí  öäüëï'.encode('iso-8859-1')
b'\xc3\xb2\xc3\xa0\xc3\xb9\xc3\xa8\xc3\xac  
\xc3\xb3\xc3\xa1\xc3\xba\xc3\xa9\xc3\xad  
\xc3\xb6\xc3\xa4\xc3\xbc\xc3\xab\xc3\xaf'
>>> 'òàùèì'.encode('utf-8')
b'\xc3\x83\xc2\xb2\xc3\x83\xc2\xa0\xc3\x83\xc2\xb9\xc3\x83\xc2\xa8\xc3\x83\xc2\xac'

I think there might be some conflict between the IO encoding that I specified 
and the one that my terminal actually uses, but I couldn't figure out what's 
going on exactly (it also weird that only 'à' and 'í' are not displayed 
correctly). Unless this behavior is expected I'll open another issue about it.

That seems more like an oversight than a deliberate restriction. Does

3.x doesn't use FILE pointers for the main I/O library (it uses unbuffered I/O

me is the debug() function vanishing on us - something not good is happening on 
interpreter shutdown.

[issue9162] License for multiprocessing files

[Jesse Noller]

Jesse Noller  added the comment:

Hi Stefan - I'm familiar with the license/etc of the original module. This bug 
isn't urgent; I shot a quick email to the PSF's secretary Pat to confirm we 
have a contributor agreement however.

Jesse, there's no doubt that you know the original license. :)

I should have been more verbose: My BSD comment was intended for public

Also, GetFinalPathNameByHandle() is called 5 times with VOLUME_NAME_DOS, and 
once with VOLUME_NAME_NT.  This one looks suspect to me.

Thanks. The patch looks good and I'd be +1 on applying it.

The only problem I see is that we may have to follow the deprecation
process.

OTOH, I've announce the plan in 2004 and confirmed it again in 2005:

[issue1578269] Add os.symlink() and os.path.islink() support for Windows

[Jason R. Coombs]

Jason R. Coombs  added the comment:

Here's a patch to address the posix failures:

- test_posixpath seems to have lost the creation of one test file.
- WindowsError doesn't exist on other platforms, so it can't be caught directly 
(in tarfile.py). I've written a work-around, but I don't particularly like it 
(catches all exceptions and tests the name).

There were three other tests that reported BAD for me.

test_os and test_subprocess were reporting bad due to skipped tests. I presume 
this will not break the buildbots?

test_readline is failing on readline.clear_history because it appears that 
attribute doesn't exist. I suspect this error is not related to the symlink 
patch.

[issue9033] cmd module tab misbehavior

[Ronald Oussoren]

Ronald Oussoren  added the comment:

We either have to add some translation, or tweak parts of python:

* the cmd module needs to learn how to configure libedit when
  the readline extension was linked to libedit

* the rlcompleter documentation needs to be updated to do the same

And that's just the stdlib. IIRC ipython contains code that uses libedit
style configuration instead of readline when using /usr/bin/python on OSX, and 
there are probably other.

IMHO the current behavior is confusing: the module is named readline, but 
sometimes uses libedit behavior. At least I ensured that the usage of libedit 
can be detected by introspecting readline.__doc__.

A basic translator shouldn't be that hard...

Okay, I'm not sure exactly how I'm supposed to go about this.  Here's  
the output from diff   for sndhdr.py

131d130
< import wave
135,141c134,138
< f.seek(0)
< try:
< w = wave.openfp(f, 'r')
< except (EOFError, wave.Error):

 > return 'wav', rate, nchannels, -1, sample_bits
$

All I did was use test_aifc() as inspiration, so the patched sndhdr.py  
calls wave.py to get the file parameters.

Here's the new test_wav() in its entirety:


def test_wav(h, f):
 import wave
 # 'RIFF'  'WAVE' 'fmt ' 
 if h[:4] != 'RIFF' or h[8:12] != 'WAVE' or h[12:16] != 'fmt ':
 return None
 f.seek(0)
 try:
 w = wave.openfp(f, 'r')
 except (EOFError, wave.Error):
 return None
 return ('wav', w.getframerate(), w.getnchannels(), \
 w.getnframes(), 8*w.getsampwidth())


If you want anything else, please ask.

[issue4044] test_output_textcalendar fails on non-englisch locale

[R. David Murray]

R. David Murray  added the comment:

This passes for me on linux (2.7), which is what I would expect, since the 
locale should not actually affect a python program unless locale.setlocale is 
called, which regrtest doesn't do.

I also tried OSX 2.7+, and the 10.4 system python (2.6.1).  test_calendar 
passed using the specified command line in all cases.

Can anyone reproduce this issue?

[issue444582] Finding programs in PATH, adding shutil.which

[Jan Killian]

Jan Killian  added the comment:

@tarek:

Sorry for not reacting, it completely vaporized out of my head. I'll do the 
patch this weekend.

Agree, only which/which_files belong to public API.

Regarding PATHEXT:

1. When a new process is created, the value is taken from registry variable 
PATHEXT in the 'HKCU\Environment' key, or the 
'HKLM\System\CurrentControlSet\Control\Session Manager\Environment' key (in 
this order). The first key is for custom user values, and PATHEXT is not set by 
default there. The second key is a system-wide setting and defaults to:
A. ".COM;.EXE;.BAT;.CMD" in Windows NT, and possibly also W2K (although it is 
already 5.0 version)
B. ".COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH" in Wine [01], XP and WS 
2003 [02]
C. ".COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC" in Vista and W7 and 
possibly also WS 2008.

2. When the PATHEXT is missing, or is set to be empty in registry, or  is set 
to be empty in the shell via "set PATHEXT=", then:
A. CMD.EXE, START.EXE and standard exec do use the default value, which is 
probably hardcoded somewhere (not taken from registry) ... tested on XP only
B. Wine [11] uses a hardcoded ".BAT;.COM;.CMD;.EXE" (I can't say I do see the 
reasons for this particular order)
C. GnuWin32 which utility [12] uses a hardcoded ".COM;.EXE;.BAT;.CMD"

So, in the corner case when the PATHEXT is set empty for whatever reason, we 
have basically the following options:

1. Find some magical way how to get the default value from windows. Any brave 
soul to fight this?

2. Stick with basic NT setting ".COM;.EXE;.BAT;.CMD", and document that it 
doesn't always match the execution behaviour in this case, eg. that .JS file 
would get executed on XP, but won't be found by which()

3. Resemble CMD.EXE/START.EXE and standard windows exec behavior, and hardcode 
the values for different windows versions from NT to W7, and for Wine. This is 
quite simple to do, as windows versions are well documented in 
platform.release()(we don't actually have to call this function, just check 
into which of the 3 intervals the current windows version fits). To do so, I 
only need someone to verify the correct default PATHEXT for W2K and WS 2008, as 
I do not have access to these.

My .02$ for 3, as this is what user expects.

What do you think?

[issue1147646] Windows deadlock with PyEval_ReleaseLock

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc  added the comment:

This issue looks invalid to me: PyEval_ReleaseLock manipulates the interpreter 
lock, but not the thread state.
Both have to be released/reset before another thread can install its own thread 
state and run.

In other words, PyEval_SaveThread() should be used instead (and 
PyEval_RestoreThread() at the end, but the example code does not care to 
finalize the interpreter)

Yes, it's an issue in py3k. Also, I prefer the behavior of 2.5, but
I'm not sure if that can be changed easily in 2.7.

[issue7268] 2to3 execfile conversion changes behavior

[Éric Araujo]

Éric Araujo  added the comment:

Not sure if this merits a new bug report: The conversion currently promotes the 
open().read() anti-pattern, which is not guaranteed to release file handles as 
soon as possible in all VMs. Using a with block would fix that.
