[issue12319] [http.client] HTTPConnection.putrequest not support chunked Transfer-Encodings to send data

2011-06-15 Thread harobed

harobed steph...@harobed.org added the comment:

 Now I'm confused. Per the HTTP specification, GET requests don't have
a body, so Transfer-Encoding: chunked doesn't apply to them.

 Are you sure you don't confuse with the response that the server
sends? In responses, Transfer-Encoding: chunked is very common.

Sorry, yes GET requests have Transfer-Encoding: chunked in server response.
PUT requests can send body data in transfer-encoding chunked mode.

[issue12327] in HTTPConnection the are len(body) and TypeError catch exception to detect if body is file like object, this hack do work with StringIO object

2011-06-15 Thread harobed

harobed steph...@harobed.org added the comment:

 But if the len information is available, why not return it?

I use HTTPConnection to simulate Apple Finder WebDAV client.
When this WebDAV client do PUT request, it transmit data in chunked encoding 
mode and not set Content-Length HTTP field.

Do you understand my context ?

Regards,
Stephane

[issue12328] multiprocessing's overlapped PipeConnection on Windows

2011-06-15 Thread sbt

sbt shibt...@gmail.com added the comment:

pipe_interruptible.patch is a patch to support to making poll() interruptible.  
It applies on top of pipe_poll_2.patch.

I am not sure what the guarantees are for when KeyboardInterrupt will be raised.

I would have done it a bit differently if I knew a good way to test whether the 
current thread is the main one.  Maybe there should be something like 
PyThread_is_main() and/or threading.ismain().

[issue12338] multiprocessing.util._eintr_retry doen't recalculate timeouts

2011-06-15 Thread sbt

New submission from sbt shibt...@gmail.com:

multiprocessing.util._eintr_retry is only used to wrap select.select, but it 
fails to recalculate timeouts.

Also, it will never retry the function it wraps because of a missing import 
errno.

I think it would be better to just implement the retrying version of select 
directly.

[issue12313] make install misses packaging module

2011-06-15 Thread Éric Araujo

Éric Araujo mer...@netwok.org added the comment:

 Nice to see my search didn't find this bug. ;)
Do you remember what search terms you tried?

 I already committed a change to install packaging, but you may want to
 revert that and commit the patch in this issue.
I honestly don’t know.  Do we have a policy about using intermediary variables 
(like XMLLIBSUBDIRS) or not?  Can we assume find(1) exists on the system and 
use it?

Ah, this changes the situation.  I suppose it’s too late to stop pretending 
that HTML and XHTML are nearly the same thing (IOW change the doc), so apos 
needs to be defined for XHTML.

IMO, we need a way to have the right entity references for HTML 4.01, XHTML 1.0

2011-06-15 Thread R. David Murray

R. David Murray rdmur...@bitdance.com added the comment:

The code you are suggesting patching is trying its best to return a length.  If 
that code needs to be fixed to not throw an error when confronted with a 
StringIO, then it should do its best to return a length.  Your original message 
on the ticket did not mention chunked encoding, and indeed that appears to be 
correct.  This bug doesn't appear, from what you have written and what I see in 
the 3.x code, to have anything to do with chunked encoding.

[issue12339] logging.Formatter.format() assumes exception to support str() method which is not true for many libraries.

2011-06-15 Thread Piotr Czachur

New submission from Piotr Czachur zim...@gmail.com:

If I want my application to be bullet-proof against external libraries that can 
(and often do) raise Exception(u'nonascii'), I cannot use python's 
logger.exception() directly, as it will end up with UnicodeDecodeError. 

The reason is hidden in Formatter.format() which does:
s = self._fmt % record.__dict__

One can use his own formatter that can handle UnicodeDecodeError, but many 
users are quite unaware of such issue and it would be great if Python can 
handle it by itself.


Here is a simple case.

 e = Exception(u'ą')
 logging.basicConfig()
 logging.getLogger('general').exception(u'ą')
ą
None
 logging.getLogger('general').exception(e)
Traceback (most recent call last):
  File /usr/lib/python2.7/logging/__init__.py, line 842, in emit
msg = self.format(record)
  File /usr/lib/python2.7/logging/__init__.py, line 719, in format
return fmt.format(record)
  File /usr/lib/python2.7/logging/__init__.py, line 467, in format
s = self._fmt % record.__dict__
UnicodeEncodeError: 'ascii' codec can't encode character u'\u0105' in position 
0: ordinal not in range(128)
Logged from file stdin, line 1

[issue11934] build with --prefix=/dev/null and zlib enabled in Modules/Setup failed

2011-06-15 Thread R. David Murray

R. David Murray rdmur...@bitdance.com added the comment:

I normally build using --prefix, often with --prefix=/dev/null, and I can't 
recall any version not building zlib.  Of course, I don't uncomment the zlib 
entry in Modules/Setup.

As far as I can see the zlib entry is unique in Setup in using prefix, so it 
probably is a bug (or, rather, a holdover from when there were various issues 
with the platform zlib).

[issue12339] logging.Formatter.format() assumes exception to support str() method which is not true for many libraries.

2011-06-15 Thread Vinay Sajip

Vinay Sajip vinay_sa...@yahoo.co.uk added the comment:

This is happening because if you pass an object instead of a string as the 
first argument in a logging call, it's treated as a message object whose 
__str__() will be called to get the actual message when it's needed, as 
documented here:

http://docs.python.org/howto/logging.html#arbitrary-object-messages

If, instead, you do it like this:

# coding: utf-8
import logging

logging.basicConfig()
try:
raise Exception(u'ą')
except Exception:
logging.getLogger('general').exception(u'An error occurred')

you get

ERROR:general:An error occurred
Traceback (most recent call last):
  File bug_12339.py, line 6, in module
raise Exception(u'ą')
Exception: \u0105

2011-06-15 Thread Éric Araujo

Éric Araujo mer...@netwok.org added the comment:

Thanks!  In my latest message, I had forgotten that msgfmt was in Tools, not in 
the standard library, and as such has no automated regression tests.  Features 
get added and bugs get fixed after manual testing only, so I will commit your 
patch (modulo the unneeded global statement) without tests (but after manual 
testing) unless someone objects.

[issue12335] pysetup create will clobber an existing setup.cfg

2011-06-15 Thread Éric Araujo

Éric Araujo mer...@netwok.org added the comment:

Well, create is not update :)  In its current form, create will save an 
existing setup.cfg as setup.cfg.old and generate a new one.  The human operator 
will then have to merge both files if necessary.  Automatically merging the old 
file into the new one would raise issues with respect to comments, whitespace 
and all that in Pythons  3.2.

The doc and help messages are probably unclear about that.

I missed the setup.cfg.old.  I think that's fine.  Probably `create` should
print a message that it moved setup.cfg to setup.cfg.old.

[issue12340] Access violation when using the C version of the io module

2011-06-15 Thread OscarL

New submission from OscarL oscar.le...@gmail.com:

This is on Windows XP SP2. Using Python 2.7.1 and 2.7.2.

While executing the unit tests of the PySerial package, version 2.5 
(http://pypi.python.org/pypi/pyserial) one of the tests fails when using the C 
version of the io module (io), but pass if the pure Python version is used 
(_pyio.py).

The specific test case in question is: test_iolib.py. When executed like:

 python test_iolib.py loop://

the test fails with the following traceback:


Traceback (most recent call last):
  File C:\pyserial-2.5\test\test_iolib.py, line 68, in test_hello_raw

self.failUnlessEqual(hello, unicode(hello\n))
AssertionError: u'memory at 0x00C5D940' != u'hello\n'


And Windows shows a crash report dialog, with the following information:


AppName: python.exe  AppVer: 0.0.0.0 ModName: python27.dll
ModVer: 2.7.2150.1013Offset: 00089f57

Exception Information
Code: 0xc005Flags: 0x
Record: 0x  Address: 0x1e089f57


As said above, if in the said test case, instead of import io one does 
import _pyio as io, the crash does not happens, and the test succeeds.

[issue12341] Some additions to .hgignore

2011-06-15 Thread Sandro Tosi

New submission from Sandro Tosi sandro.t...@gmail.com:

following http://docs.python.org/devguide/coverage.html doc you'll end
up with several new files/dirs in your checkout:

- .coverage, used by coveragepy to save its info
- coverage/ , the symlink to coveragepy/coverage
- htmlcov/ , the dir where the coverage HTML pages are written

I think they should be added to .hgignore so that hg st won't show them, and 
the attached patch just does it. It's meant for 'default' but should there be 
no problem to backport it to previous branches.

[issue1711800] SequenceMatcher bug with insert/delete block after replace

2011-06-15 Thread Terry J. Reedy

Terry J. Reedy tjre...@udel.edu added the comment:

I believe this issue should be closed and have set it to pending.

The original report of a 'bug' and the two 'testcases' were and are invalid as 
they are based on an incorrect understanding of SequenceMatcher. It is not a 
diff program and in particular not a line diff program but the function used 
internally by such. It works on sequences of characters, lines, numbers, or 
anything else. Given the character strings 'abc' and 'abcd\def' it correctly 
reports that the second is a copy of 3 chars from the first plus insertion of 5 
more.

Gabriel correctly suggested the above in suggesting that if one wants to 
compare sequences of text lines, one might use Differ. One could also use 
SequenceMatcher directly, but this loses the diff-like formatting and report of 
within-line differences. I think this issue should have been closed then.

I do not know what functionality Andrew thinks Christian was talking about. 
Using Differ with

a = ['abc\n']
b = ['abcd\n', 'def\n']
for line in difflib.Differ().compare(a,b): print(line, end='')

# prints
- abc
+ abcd
?+
+ def

One line is replaced with two, with the extra info that the first new line is 
the old line with an extra char. I do not believe that 'any diffing program' 
will report the latter. The '?' lines are easily filtered out if not wanted.

The patch by Peter has no motivation that I can see other than the idea that 
replacing a subsequence with one of a different length is somehow bad. Tim 
Peters did not think so and neither do I -- or Guido. Unequal replacement is 
built into the syntax of Python:

 s = [1,2,3]
 s[1:2] = [4,5,6]
 s
[1, 4, 5, 6, 3]

I would not be surprised it the proposed change broke some existing application 
or degraded performance a bit.

U+1 is not the most common character in fonts. You should try another

Extract of http://wiki.tcl.tk/1364 :

RS 2008-07-09: Unicode out of BMP ( U+) requires a deeper rework of Tcl 
and Tk: we'd need 32 bit chars and/or surrogate pairs. UTF-8 at least can deal 
with 31-bit Unicodes by principle.

 I don't think there is anything practical IDLE
 or tkinter can do about that.

We might raise an error with better error message than ValueError('unsupported 
character'), but it's maybe overkill.

[issue12328] multiprocessing's overlapped PipeConnection on Windows

2011-06-15 Thread Antoine Pitrou

Antoine Pitrou pit...@free.fr added the comment:

 pipe_interruptible.patch is a patch to support to making poll()
 interruptible.  It applies on top of pipe_poll_2.patch.

Hmm, it seems to me that it should be done in _poll() instead. Otherwise, 
recv() will not be interruptible, will it?

Also, after looking at this again, it seems sigint_event would be better 
provided (at the C level) by the Python core, e.g. as _PyOS_SigintEvent. The 
time module already uses a similar mechanism.

By setting the event in the sigint handler itself, rather than in an auxiliary 
HandlerRoutine callback function, it should also ensure that, when the event is 
set, the tripped bit in signalmodule.c has been set, meaning we wouldn't need 
to Sleep() anymore.

(I also wonder why the event isn't auto-reset. Otherwise, there's a race 
condition - which is probably harmless in most cases, but still.)

[issue12340] Access violation when using the C version of the io module

2011-06-15 Thread Santoso Wijaya

Santoso Wijaya santoso.wij...@gmail.com added the comment:

Regarding the crash,

From what I can see, the `tp_clear` method of bufferedrwpair is called during 
Py_Finalize() that leads to garbage collection. This NULLs `self-writer` for 
the rwpair object.

Later, in the same garbage collection routine, the `tp_clear` of textio (the 
wrapper) is called. This attempts to finalize its wrapped object by first 
calling the `closed` property of the wrapped object. This property read is 
propagated down to the wrapped bufferedrwpair, `bufferedrwpair_closed_get()`.

At this point, `self-writer` for the bufferedrwpair object is already NULL 
from the previous clear. Hence, the crash happens because a NULL pointer 
dereferencing is attempted.

[issue12000] SSL certificate verification failed if no dNSName entry in subjectAltName

2011-06-15 Thread Mads Kiilerich

Mads Kiilerich m...@kiilerich.com added the comment:

Nicolas Bareil wrote, On 05/07/2011 09:48 AM:
 Do you think this test should fail?

Until now I have considered this behaviour OK but undocumented and 
officially unsupported in Python. One (the best?) reason for considering 
it OK is that if someone (intentionally or not) trusts a certificate 
that happens to have the textual representation of an IP address in 
commonName then there is no doubt what the intention with that is. This 
case is thus within what i considered secure behaviour.

But the more I look at it the more convinced I get that this test should 
fail. RFC 2818 mentions subjectAltName iPAddress as a must for IP 
addresses - even though it only uses a lower-case and thus 
perhaps-not-necessarily-authoritative must. But the best argument 
against IP in commonName is that it isn't mentioned anywhere, and when 
it isn't explicitly permitted we should consider it forbidden.

A consequence of that is that my previous concern is invalid. There is 
no reason the presence of a subjectAltName iPAddress should prevent 
fallback from dNSName to commonName.

Windows Vista and later
 - fix usage of the default character on encoding, depending on the code page 
(incompatible with CP_UTF7 and CP_UTF8)
 - add some more unit tests
 - read the windows version only once, at startup
 - decode_code_page_chunk() now adjusts the input size depending on the final

[issue12343] Python 2.7.2 regression: ssl.SSLError: [Errno 2] _ssl.c:503: The operation did not complete (read)

2011-06-15 Thread Jesús Cea Avión

New submission from Jesús Cea Avión j...@jcea.es:

Combining non-blocking SSL sockets and select() raises ssl.SSLError: [Errno 
2] _ssl.c:503: The operation did not complete (read) in Python 2.7.2, but 
works OK in 2.7.1, 2.6.* and previous.

This test shows the issue:


import ssl
import socket
import select

s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.connect((gmail.com, 443))
s.setblocking(0)
s = ssl.wrap_socket(s)
s.write(GET / HTTP/1.0\r\nHost: gmail.com\r\n\r\n)
select.select([s], [], [])

s.read(999)
print OK!


Under python 2.6 and 2.7.1 I get OK, but under 2.7.2 I get:


Traceback (most recent call last):
  File z.py, line 8, in module
s = ssl.wrap_socket(s)
  File /usr/local/lib/python2.7/ssl.py, line 372, in wrap_socket
ciphers=ciphers)
  File /usr/local/lib/python2.7/ssl.py, line 134, in __init__
self.do_handshake()
  File /usr/local/lib/python2.7/ssl.py, line 296, in do_handshake
self._sslobj.do_handshake()
ssl.SSLError: [Errno 2] _ssl.c:503: The operation did not complete (read)


Changing the order between the s.setblocking() and the ssl.wrap_socket() 
seems to solve the issue in this particular code sample, but this seems to be a 
serious regression in 2.7.2. I have programs in production here where changing 
the order doesn't solve the exception :-(. Dead in the water! :-(

[issue12344] A kind of 'reinitialize_command' function which can initialize a command with key-value pair should be added for Command class

2011-06-15 Thread higery

New submission from higery shoulderhig...@gmail.com:

There is a 'reinitialize_command' function in setuptools' command class which 
can initialize a command with a key-value pair, but it seems that 
distutils2/packaging does not yet have this function. I think it's useful in 
the condition that we want to run some commands with some options initialized. 

For instance,  if we want to run 'build_ext' command with its 'inplace' option 
initialized, we can use : self.reinitialize_command('build_ext', inplace=1), 
and then self.run_command('build_ext') .

[issue12345] Add math.tau

2011-06-15 Thread Nick Coghlan

New submission from Nick Coghlan ncogh...@gmail.com:

I'd like to add a new constant to the math module:

  tau = 2*math.pi

Rather than repeating all the reasons for why tau makes more sense than pi as 
the fundamental circle constant, I'll just refer interested readers to 
http://tauday.com/

[issue11549] Build-out an AST optimizer, moving some functionality out of the peephole optimizer

2011-06-15 Thread Eugene Toder

Eugene Toder elto...@gmail.com added the comment:

I found a problem in constant de-duplication, already performed by compiler, 
that needs to be fixed before this change can be merged. 

Compiler tries to eliminate duplicate constants by putting them into a dict. 
However, duplicate in this case doesn't mean just equal, we need a stronger 
relationship, as there are many equal values that behave differently in some 
contexts, e.g. 0 and 0.0 and False or 0.0 and -0.0. To this end for each value 
we create a tuple of the value and it's type and have some logic for -0.0. This 
is handled in compiler_add_o in Python/compile.c.

This logic, however, only works for scalar values -- if we get a container with 
0 and the same container with False we collapse them into one. This was not a 
problem before, because constant tuples were only created by peephole, which 
doesn't attempt de-duplication. If tuple folding is moved to AST we start 
hitting this problem:

 dis(lambda: print((0,1),(False,True)))
  1   0 LOAD_GLOBAL  0 (print)
  3 LOAD_CONST   1 ((0, 1))
  6 LOAD_CONST   1 ((0, 1))
  9 CALL_FUNCTION2
 12 RETURN_VALUE

The cleanest solution seems to be to introduce a new rich comparison code: 
Py_EQUIV (equivalent) and implement it at least in types that we support in 
marshal. This will simplify compiler_add_o quite a bit and make it work for 
tuples and frozensets.
I'm open to other suggestions.

[issue12345] Add math.tau

2011-06-15 Thread Benjamin Peterson

Benjamin Peterson benja...@python.org added the comment:

Perhaps we should wait until \tau gains popularity larger than some impassioned 
physicist. \tau has been used to represent the golden ratio longer.
