Python for Qt version 1.0.0~beta3 salmiak released
The PySide team is happy to announce the third beta release of PySide: Python for Qt. New versions of some of the PySide toolchain components apiextractor, shiboken, libpyside have been released as well. This is a source code release only; we hope our community packagers will be providing provide binary packages shortly. To acquire the source code packages, refer to our download wiki page [1] or pull the relevant tagged versions from our git repositories [2]. Major changes since 1.0.0~beta2 === This is a bugfix release. Since beta2, a total of 35 high-priority bugs have been fixed. See the list of fixed bugs at the end of this message. Path towards 1.0 release There are still some outstanding bugs in our Bugzilla [3]. To have these fixed, we plan to do a new beta in two weeks. After that we will check the possibility of a release candidate or other beta before 1.0. About PySide PySide is the Nokia-sponsored Python Qt bindings project, providing access to not only the complete Qt 4.7 framework but also Qt Mobility, as well as to generator tools for rapidly generating bindings for any Qt-based libraries. The PySide project is developed in the open, with all facilities you'd expect from any modern OSS project such as all code in a git repository [2], an open Bugzilla [5] for reporting bugs, and an open design process [4]. We welcome any contribution without requiring a transfer of copyright.

Re: [PyQt] Working with PyQt and Pydev
On Thu, Jan 6, 2011 at 9:32 AM, Rohit Coder passionate_program...@hotmail.com wrote: I installed the PyDev plugin into Aptana Stdui 3 Beta. Someone suggested me to use PyQt for Python GUI app, and so I downloaded and installed PyQt. But when I open Aptana Studio, I could see a new menu added with the name PyDev, but there is nothing for PyQt. In the Windows Start Meny item list, I could see a folder named PyQt and when I open it, there are few tools like Designer. When Designer is run, it opens Qt IDE for designing Forms like Visual Studio and the files have the extension .ui. I want to know how to integrate PyQt and PyDev. Do I need to use them separately by adding the .ui files to PyDev and then adding Python core code for functionality? After you design your class in the Qt Designer, you need to run pyuic to convert the .ui file to a python file (which you'd probably subclass in another module to add your own code, as you don't want to mess the automatically generated file). If you want, you can add a builder (project properties builders) to run pyuic when a .ui file is changed, so you don't have to go to the console to ask pyuic to be rerun every time you change the file.

Re: PEP: possibility of inline using of a symbol instead of import
On Jan 6, 7:28 am, dmitrey dmitrey.kros...@scipy.org wrote:
hi all,
I have th PEP (I'm not sure something like that hadn't been proposed
although):
very often in a Python file header the following lines are present,
like:
from MyModule1 import myFunc1
import MyModule2 as mm2
from MyModule3 import myFunc3 as mf3
etc
and after several pages of code they are using somewhere, maybe only
one time, e.g.
r1 = myFunc1(...)
r2 = mm2.myFunc2(...)
r3 = mf3(...)
It makes programs less clear, you have to scroll several pages of code
in IDE to understand what it refers to.
I propose to add possibility of using a symbol instead (for simplicity
I use @ here, that is already reserved for decorators, thus it should
be other symbol, maybe from Unicode although for simplicity to type it
I would prefer something ordinary like $ or ` or !).
e.g. instead of
import MyModule
(...lots of code...)
r = MyModule.myFunc(...)
someone could just type in the single place
r = @MyModule.myFunc(...)
Also, import MyModule2 as mm2 could be replaced to mere
mm2 = @MyModule2
and from MyModule3 import myFunc3 as mf3 could be replaced to mere
mf3 = @MyModule3.myFunc3.
As for __import__(ModuleTextName), it could be replaced to something
like @(ModuleTextName) or @{ModuleTextName} or @[ModuleTextName].
I actually wouldn't mind this; in fact Python's importing mechanism is
bad enough that a complete overhaul might not be a bad thing.
But, first of all, one can already do in-line imports in Python with
the __import__ built-in function (and I used to do this frequently in
throwaway scripts before list comprehensions were added). For
instance, a one-liner to generate a password would be this:
python -c 'for i in xrange(8):
__import__(sys).stdout.write(__import__(random).choice(__import__(string).letters))'
Today a better way to do it would be like this:
python -c 'import random,string; print
.join(random.choice(string.letters) for i in xrange(8))'
But that's a digression.
The problem with in-line imports is that it can lead to deadlock in
multithreaded programs, so for the most part it's a good idea to avoid
importing within functions.
Therefore, a syntax for it would really be needed to gain full
benefit. This would allow the compiler to scan the file to collect a
list of prerequisite modules. In my mind, the module itself wouldn't
import the dependencies itself, it simply lists prerequisites and
leaves it to the runtime to ensure that they've been imported.
A side benefit to this is to keep module namespaces clean.
Main drawback is that it makes accessing symbols in deepely nested
packages unwieldy (since presumably you'd have to write out the fully-
qualified name). Meh, I pretty much avoid deeply nested packages, and
typically spell out the fully-qualified module names anyway. So not
my problem.
As for listing imports at the top of the program--I can't say I have
much use for it. Sometimes it helps to see a list of prerqequisites
in one place, but I can't say it's the most useful thing ever, and
anyway it's misleading since the imports can become stale. I'd rather
not have to stop and scroll up ten pages to add an import to the top
of the module when I suddenly need to access time.sleep or
itertools.count.
So, pending a better syntax, I'll give it a +0; and the only reason I
don't give it a +1 is it's such a drastic change.
The syntax probably would deserve a lot of thought (being such a
drastic change) but drawing from C++ a postfix operator would seem to
fit.
sys:: - evaulates to the sys module
sys::version - evaluates to sys.version
xml::etree::ElementTree:: - as expected
That has the unfortunate effect of making Python look like C++ though.
Won't ever happen though.

Close stdout socket on CGI after fork with subprocess
Hi, I work with Python 2.4 and CGI. I have a CGI which call a Python script in background process and return result before background task is finished. Actually, the browser displays response but it is waiting for end of background task because the socket is not closed. Internet told me that I must close the stdout file descriptor (sys.stdout.close()) to close the socket but it doesn't work. The background task is launched via subprocess.Popen and is attached to the root process on ps command. Any idea ? Thanks Thibaud -- http://mail.python.org/mailman/listinfo/python-list

os.system and loggers
hi, I'm using a 3rd-party python program that uses the python logging
facility and also makes calls to os.system. I'm trying to capture its
output to a file.
In my own code, I've taken control of the loggers that are setup in
the other program by removing its StreamHandler and replacing with
FileHander. But when it comes to the call to os.system I'm at a loss.
I want to capture the stdout from that os.system call in my
FileHandler. I thought this might work, before I call the other
program's class/method:
sys.stdout = getLogger('status').handlers[0].stream
but no dice. Is there any clean way to get what I want? If not, I
guess I'll override the other method with my own, but it will
basically be a bunch of code copied with os.sytem replaced with
subprocess, using getLogger('status').handlers[0].stream for stdout/
stderr.

That is true (that __getattr__ is called only if the attribute doesn't
exist), however deepcopy works by creating a new instance *without*
calling __init__. When it is copying the attributes self.d *doesn't*
exist initially. You should work around this case in your __getattr__
if you want your object to be deep-copyable.

.. except KeyError:
.. raise AttributeError

I've tested the above code in Python versions 2.4 through 3.2 and the
only one that prints that message is 2.6.

Re: Can I have both Python 2.7 and Python 3.1 at the same time on the Mac?
MacPorts! They include a nifty little package called python_select that lets you switch default python versions on-the-fly and organizes everything for you perfectly. I have python 2.4, 2.5, 2.6, 2.7, 3.2, and the system default 2.6.1 all installed, and python_select python27 python_select python32 python_select python26-apple switches seamlessly between them.

I've also seen various resources indicate that one can install both Python 2.7 and Python 3.1 -- but when I did this, I get no end of problems in the 2.7 install. IDLE, in particular, fails rather spectacularly, even if I launch it directly from the Python 2.7 directory in which it resides. So, either I've been misled and should only try to have one or the other. OR I'm missing some (probably simple) step that's mucking me up. Help? Yes, you can have multiple versions of Python installed on Mac OS X. In fact, Apple ships multiple versions of Python with OS X (2.6 and 2.6 with OS X 10.6, for example). Starting with Python 2.7, python.org offers two variants of OS X installers, one is 32-bit-only and works on all versions of OS X 10.3.9 through OS X 10.6, the other supports 64-bit execution and only works on 10.6 (as of 2.7.1). Unfortunately, there are some major interaction problems between Tkinter, Python's GUI toolkit which is used by IDLE, and the Tcl/Tk 8.5 supplied by Apple in OS X 10.6. I'm assuming you installed the 64-bit version. If so, until the problem is resolved in the next maintenance release of Python 2.7, I suggest you download and install the 32-bit-only version of Python 2.7.1 which does not have those problems. Thank you, Ned! Installing what appeared to be the 'old OS' version seems to fix my difficulty. IDLE now works fine without hanging, I can enter code, save, check syntax, and run from the 'new window'. And 3.1 still works as before. regards, Bill -- http://mail.python.org/mailman/listinfo/python-list -- Jason M.

The python.org installers take the route of providing a shell script app for each version to modify your shell login profile to insert that version's bin directory at the head of the $PATH env variable.

Your code can be simplified significantly.
In particular:
- Don't add single-element lists. Use the list.append() method instead.
- One seldom manually tracks counters like `i` in Python; use range()
or enumerate() instead.
- Lists have a multiply method which gives the concatenation of n
copies of the list.
Revised version (untested obviously):
inputfile = file('sample.pdf','rb')# This is PDF with
which we will work
lines = inputfile.readlines() # read file one line at a time
linestart = [] # Starting address for each line
lineend = []# Ending address for each line
linetype = ['normal']*len(lines)
print len(lines)# print number of lines
addr = 0# and address pointer
for line in lines: # Go through each line
linestart.append(addr)
length = len(line)
lineend.append(addr + (length-1))
addr += length
for i, line in enumerate(lines):
if line.find(' obj') 0:
linetype[i] = 'object'
print At address ,linestart[i],object found at line ,i,: , line
if line.find('endobj') 0:
linetype[i] = 'endobj'
print At address ,linestart[i],endobj found at line ,i,: , line
As to the bug: I think you want != -1 rather than 0 for your
conditionals; remember that Python list/string indices are 0-based.

Chris

That's incorrect. readlines() reads the entire file in one go, and splits
it into individual lines.
linestart = [] # Starting address for
each line
lineend = []# Ending
address for each line
linetype = []
*raises eyebrow*
How is an empty list a starting or ending address?
The only thing worse than no comments where you need them is misleading
comments. A variable called linestart implies that it should be a
position, e.g. linestart = 0. Or possibly a flag.
print len(lines)# print number of lines
i = 0 # define an iterator, i
Again, 0 is not an iterator. 0 is a number.
addr = 0# and address pointer
while i len(lines): # Go through each line
linestart = linestart + [addr]
length = len(lines[i])
lineend = lineend + [addr + (length-1)] addr = addr + length
i = i + 1
Complicated and confusing and not the way to do it in Python. Something
like this is much simpler:
linetypes = [] # note plural
inputfile = open('sample.pdf','rb') # Don't use file, use open.
for line_number, line in enumerate(inputfile):
# Process one line at a time. No need for that nonsense with manually
# tracked line numbers, enumerate() does that for us.
# No need to initialise linetypes.
status = 'normal'
i = line.find(' obj')
if i = 0:
print Object found at offset %d in line %d % (i, line_number)
status = 'object'
i = line.find('endobj')
if i = 0:
print endobj found at offset %d in line %d % (i, line_number)
if status == 'normal': status = 'endobj'
else: status = 'object endobj' # both found on the one line
linetypes.append(status)
# What if obj or endobj exist more than once in a line?
One last thing... if PDF files are a binary format, what makes you think
that they can be processed line-by-line? They may not have lines, except
by accident.

What's going on here? I really appreciate any help! After talking a bit with Alex Grönholm it seems this is an issue raised fairly often (not always in the context of this package) and is not really a problem with APScheduler. It has far more to do with attempting to start a thread, then immediately exiting the main thread. That's not how threading is supposed to be used, so don't do it. ;) APScheduler 2.0 adds some improved examples, according to Alex, that don't suffer the problem demonstrated by the short code snippit you provided. A package of mine, TurboMail, suffers from the same threading issue if used improperly; you enqueue e-mail, it starts a thread, then you immediately exit. TM tries to work around the issue, but in most cases that workaround does not work properly. (You get strange uncatchable exceptions printed on stderr though AFIK the e-mail does get sent correctly, your application may hang waiting for the thread pool to drain if you have a minimum thread count option set.)

[issue10845] test_multiprocessing failure under Windows
Terry J. Reedy tjre...@udel.edu added the comment: On xp, changing from -m test to -m test.regrtest removed the extra craziness during and after the test run that I reported on pydev. I think making at least a tempory fix to whatever -m test runs should be a release blocker so only individual tests and not the test process are broken. If necessary, just refuse to run under windows and say to use test.regrtest as before.

[issue10512] regrtest ResourceWarning - unclosed sockets and files
STINNER Victor victor.stin...@haypocalc.com added the comment: Le vendredi 07 janvier 2011 à 02:19 +, Nadeem Vawda a écrit : Most of these leaks seem to stem from the fact that socket.SocketIO.close() doesn't behave as documented. According to its docstring, it is meant to decrement the underlying socket's refcount, and close it if the refcount drops to zero. However, to do this job it calls socket._decref_socketios(), which is defined as follows: def _decref_socketios(self): if self._io_refs 0: self._io_refs -= 1 if self._closed: self.close() Clearly, this doesn't do what the docstring describes. Changing the second conditional from if self._closed: to if self._io_refs = 0: disposes of all but one of the ResourceWarnings, but also breaks 8 tests in test_socket. It seems that the tests expect a socket to remain open after all referring SocketIO objects have been closed, which contradicts the docstring for SocketIO.close(). I suppose I should open a separate issue for this. Can you please open a new issue for that?

Nick Coghlan ncogh...@gmail.com added the comment: As per the discussion over in issue #10181, I've changed my position on this issue. Since the PEP isn't explicit on the exact semantics here, I think we should be guided by the memoryview behaviour and make it official that bf_releasebuffer implementations shouldn't trust the contents of the passed in Py_buffer struct. Instead, if that information is important, the exporter should create an internal data structure that preserves the necessary detail and merely use the Py_buffer address as an identifier to locate the internal copy. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9990 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue4953] cgi module cannot handle POST with multipart/form-data in 3.0
Glenn Linderman v+pyt...@g.nevcal.com added the comment: Pierre said: Option 1 is impossible, because the CGI script sometimes has no control on the stream : for instance on a shared web host, it will receive sys.stdin as a text stream I say: It is the user code of the CGI script that calls CGI.FieldStorage. So the user could be required (option 1) to first tweak the stdin to be bytes, one way or another. I don't understand any circumstance where a Python CGI script doesn't have control over the settings of the Python IO Stack that it is using to obtain the data... and the CGI spec is defined as a bytestream, so it must be able to read the bytes. Victor said: It is possible to test the type of the stream. I say: Yes, why just assume (as I have been) that the initial precondition is the defaults that Python imposes. Other code could have interposed something else. The user should be allowed to pass in anything that is a TextIOWrapper, or a BytesIO, and CGI should be able to deal with it. If the user passes some other type, it should be assumed to produce bytes from its read() API, and if it doesn't the user gets what he deserves (an error). Since the default Python sys.stdin is a TextIOWrapper, having CGI detect that, and extract its .buffer to use for obtaining bytes, should work fine. If the user already tweaked sys.stdin to be a BytesIO (.buffer or detach()), CGI should detect and use that. If the user substitutes a different class, it should be bytes, and that should be documented, the three cases that could work. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4953 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue9990] PyMemoryView_FromObject alters the Py_buffer after calling PyObject_GetBuffer when ndim 1
Nick Coghlan ncogh...@gmail.com added the comment: The alternative (if we declare that clients should treat Py_buffer contents as completely read-only) is to update memoryview to include a separate orig_view field that would never be touched. The GetBuffer and ReleaseBuffer calls would then use orig_view, with dup_buffer used to copy the data into the main view field before modifying it. However, this approach greatly complicates the bf_getbuffer and bf_releasebuffer implementations, since memoryview could no longer pass the supplied Py_buffer pointer straight through to the underlying implementation. Instead, for each call to bf_getbuffer, it would need to create a new Py_buffer struct, use that for the GetBuffer call to the underlying object, copy the contents over to the passed in buffer (modifying the shape information as appropriate for any slicing that is in effect), then, in bf_releasebuffer, use the passed in pointer to find the right Py_buffer struct to use in the ReleaseBuffer call. Putting the onus on exporters to be suspicious of the contents of the Py_buffer objects handed to bf_releasebuffer implementations actually seems like the more robust approach in the long run. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9990 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10181] Problems with Py_buffer management in memoryobject.c (and elsewhere?)
Mark Dickinson dicki...@gmail.com added the comment:
by the time the relevant C stack frame goes away, ReleaseBuffer should
already have been called.
Hmm. I'm not sure I understand how/when that would happen. Looking at the
current py3k code, in Objects/memoryobject.c at line 92, we have:
PyObject *
PyMemoryView_FromObject(PyObject *base)
{
PyMemoryViewObject *mview;
Py_buffer view;
if (!PyObject_CheckBuffer(base)) {
PyErr_SetString(PyExc_TypeError,
cannot make memory view because object does
not have the buffer interface);
return NULL;
}
if (PyObject_GetBuffer(base, view, PyBUF_FULL_RO) 0)
return NULL;
mview = (PyMemoryViewObject *)PyMemoryView_FromBuffer(view);
if (mview == NULL) {
PyBuffer_Release(view);
return NULL;
}
return (PyObject *)mview;
}
So here 'view' is being allocated on the stack, and its address passed to
PyObject_GetBuffer; PyBuffer_Release isn't called (except when an error
happens) before the function exits and the stack frame becomes invalid.
Sorry for the odd questions; it's clear to me that I'm misunderstanding
something fundamental, but I'm struggling to figure out what.

[issue10686] email.Generator should use unknown-8bit encoded words for headers with 8 bit data
R. David Murray rdmur...@bitdance.com added the comment: Well, unknown-8bit is registered as a charset with IANA. It is registered specifically for use in message bodies, but as a registered charset it should be acceptable in headers as well. There is no similar registration for just 'unknown', but it sounds like mailers may be more likely to accept it if it exists in the wild. I'm hoping to fix this before the RC (which is tomorrow, which means fixing it today), so your suggestion of making the 'unknown charset' token configurable is a good one. I'm not so worried about providing a way to reject such headers, since this incarnation of email makes a point of not throwing errors on parsing, and if you read binary messages with unknown bytes the best thing to do is generate the outgoing message with BytesGenerator, in which case you get the unknown bytes back without the rfc2047 munging. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10686 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10855] wave.Wave_read.close() doesn't release file
New submission from Peter Creath pjcreath+pyt...@gmail.com: Calling wave.close() fails to release all references to the file passed in via wave.open(filename_or_obj, rb). As a result, processing many wave files produces an IOError of too many files open. This bug is often masked because this dangling reference is collected if the wave object is collected. However, if the wave object is retained, calling wave_obj.close() won't release the reference, and so the file will never be closed. There are two solutions: 1) The workaround: the client program can explicitly close the file object it passed to the wave object (file_obj.close()). 2) The bug fix: the wave module can properly release the extra reference to the file, by setting self._data_chunk = None in the close() method. Explanation: Trunk code (and 2.7.1, and older): def close(self): if self._i_opened_the_file: self._i_opened_the_file.close() self._i_opened_the_file = None self._file = None but note initfp(self, file): ... self._file = Chunk(file, bigendian = 0) ... chunk = Chunk(self._file, bigendian = 0) ... self._data_chunk = chunk ... therefore close needs to add: self._data_chunk = None -- components: Library (Lib) messages: 125654 nosy: pjcreath priority: normal severity: normal status: open title: wave.Wave_read.close() doesn't release file type: resource usage versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10855 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Alexander Belopolsky belopol...@users.sourceforge.net added the comment: I think we should investigate deeper why this enhancement request didn't get into Python 3. There is nothing to investigate here. This is a request for a marginal improvement and OP did not follow up even though a core developer responded on the next day after his post. The only lesson to be learned from this is that Python improvements should be discussed on the tracker or appropriate python mailing lists and not on private blogs. -- nosy: +belopolsky ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1559549 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Brian Curtin cur...@acm.org added the comment: See _PyImport_GetDynLoadFunc in Python/dynload_win.c -- that's where this is happening. Why Python can't get information about the reason .DLL is not loaded? Windows does not provide it in the case you are speaking of. If I call LoadLibraryEx for techtonik.pyd, either it succeeds because everything is there, or it fails because something is not there. We get no information about dependency hierarchies failing to load. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10854 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10849] Backport test/__main__
Raymond Hettinger rhettin...@users.sourceforge.net added the comment: 2.6 is right out. Martin, would you please decide on whether this should be backported to 2.7 and 3.1? IMO, the rationale is flimsy (its not hard to run the test suite in *any* version) and it goes against our usual policy; however, it is also a trivial and isolated patch, making it somewhat harmless. Also note that 3.1 is very soon to be closed for anything but security fixes. Only 2.7 will in long-term maintenance. -- assignee: benjamin.peterson - loewis nosy: +loewis versions: -Python 2.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10849 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10854] Output DLL name in error message of ImportError when DLL is missing
Amaury Forgeot d'Arc amaur...@gmail.com added the comment:
The code is in Python/dynload_win.c
To load an extension module mymodule.pyd, Python calls
LoadLibrary('/path/to/mymodule.pyd'); when it returns NULL, the code calls
GetLastError() (which returns 126 in this case) then FormatMessage to get an
error message.
To get the full path to the .pyd, you can use imp.find_module(), but there is
nothing else we can do I fear.

[issue10858] Make source code links less proeminent
New submission from Antoine Pitrou pit...@free.fr: Reading library source code will only be enlightening to expert users, since most modules are not academic but real-world implementations, with all the complications it entails. Therefore, putting a link at the top of module sections is only confusing for most people. I would like to shift these links to the bottom of doc pages, where we already have see also links to RFCs and the like. -- assignee: d...@python components: Documentation messages: 125669 nosy: d...@python, pitrou, rhettinger priority: normal severity: normal status: open title: Make source code links less proeminent versions: Python 2.7, Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10858 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue10852] SSL/TLS sni use in smtp, pop, imap, nntp, ftp client libs by default
Antoine Pitrou pit...@free.fr added the comment: I understand this patch relies on #10851. As I said there, I would rather have SSLContext become the primary API, and the stdlib standardize on it. Part of the stdlib, as you have witnessed, already allows the user to pass a custom SSLContext, which is very simple way of allowing for custom user settings.

[issue10808] ssl unwrap fails with Error 0
Antoine Pitrou pit...@free.fr added the comment: As we discussed on IRC, there are two things here: - unwrap() can give an error because it tries to shutdown the SSL layer cleanly, and the other side doesn't support it or is already closed; unwrap() is useful mostly if you plan to use the clear-text layer afterwards, otherwise you can just call shutdown(socket.SHUT_RDWR) and then close() - the error message and errnos are totally bogus, but I'm afraid that's because of OpenSSL giving us this information. -- resolution: - wont fix status: open - closed versions: +Python 3.2 -Python 2.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10808 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
