[issue3890] ssl.SSLSocket.recv() implementation may not work with non-blocking sockets

[Giampaolo Rodola']

The patch seems ok to me. This is how it was supposed to be in the first place 
if ssl.py behaved as expected with non blocking sockets.

[issue1544339] _ctypes fails to build on Solaris x86 32-bit (Sun compiler)

[Nick]

Nick  added the comment:

Hello is this not the fix?  Are there any plans for patch and ctypes 1.0.3?  
ctypes is a setuptools dependency for various Python 3rd party packages, and 
this breaks any that enlist ctypes on Solaris.

[issue8199] zipfile.py: consistency between "write" and "writestr"

[Hervé Cauwelier]

New submission from Hervé Cauwelier :

Hi,

In class "ZipFile", method "write" accepts "compress_type" parameter but not 
the "writestr" method.

I see no reason for this limitation and the change is trivial.

This is needed for generating ODF documents since the mimetype file must not be 
compressed, contrary to other parts.

For now, I've copied the block of code that create a "ZipInfo" object in that 
"writestr" method.

The attached patch shows the desired change.

Thanks

[issue8047] Serialiser in ElementTree returns unicode strings in Py3k

[Florent Xicluna]

Florent Xicluna  added the comment:

http://codereview.appspot.com/664043 (patch against 3.x)

IIUC, the changes proposed (for 3.2) are:
 - default encoding or bool(encoding) == False
   ==> fallback to 'US-ASCII' encoding (instead of Unicode)
 - encoding=str or encoding='unicode'
   ==> serialize to Unicode

And it changes the behavior of :
 - ET.write()
 - tostring()
 - tostringlist()

For 2.x we could add the options for Unicode output:
 - encoding=unicode
 - and encoding='unicode'

[issue8047] Serialiser in ElementTree returns unicode strings in Py3k

The reason I chose the unicode type over a 'unicode' string name at the time 
was that I wanted to make a clear distinction to show that this is not just 
selecting a different codec but that it changes the output type.

I don't really care either way, though, given that this reads a lot less well 
in Py3. If ET supports both, lxml will follow.

[issue8200] logging module errors out if log called when multiprocessing module not finished loading

[Chris Jerdonek]

New submission from Chris Jerdonek :

The logging module errors out if the multiprocessing module is not finished 
loading when logging.log() is called.

This can happen, for example, if a custom import hook is defined that causes 
third-party code to execute when the multiprocessing module gets to an import 
statement.  (autoinstall is an example of a package that defines such an import 
hook: http://pypi.python.org/pypi/autoinstall/0.1a2 )

Here is a stack trace of the issue in action:

  File 
"/Users/chris_g4/dev/apple/WebKit-git/WebKitTools/Scripts/webkitpy/executive.py",
 line 118, in cpu_count
import multiprocessing
  File 
"/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/multiprocessing/__init__.py",
 line 60, in 
import os
  File 
"/Users/chris_g4/dev/apple/WebKit-git/WebKitTools/Scripts/webkitpy/thirdparty/autoinstall.py",
 line 279, in find_module
_logger.debug("find_module(%s, path=%s)" % (fullname, path))
  File 
"/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/logging/__init__.py",
 line 1036, in debug
self._log(DEBUG, msg, args, **kwargs)
  File 
"/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/logging/__init__.py",
 line 1164, in _log
record = self.makeRecord(self.name, level, fn, lno, msg, args, exc_info, 
func, extra)
  File 
"/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/logging/__init__.py",
 line 1139, in makeRecord
rv = LogRecord(name, level, fn, lno, msg, args, exc_info, func)
  File 
"/opt/local/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/logging/__init__.py",
 line 279, in __init__
self.processName = sys.modules['multiprocessing'].current_process().name
AttributeError: 'module' object has no attribute 'current_process'


Here is a possible fix (in logging/__init__.py):

 if not logMultiprocessing:
 self.processName = None
 # "current_process" might not be defined if multiprocessing is
 # not finished loading yet.  This can happen, for example, if
 # a custom import hook is defined that causes third-party code
 # to execute when the multiprocessing module calls import.
-elif 'multiprocessing' not in sys.modules:
+elif 'multiprocessing' not in sys.modules or \
+ 'current_process' not in dir(sys.modules['multiprocessing']):
 self.processName = 'MainProcess'
 else:
 self.processName = 
sys.modules['multiprocessing'].current_process().name
 if logProcesses and hasattr(os, 'getpid'):
 self.process = os.getpid()

There's always the possibility of adding a new official codec
called 'unicode' which converts Unicode to Unicode as no-op.

This may also be useful to have in other situations where you
want to signal a special case for Unicode input or output.

[issue8201] test_logging fails if the loggerDict contains non-ASCII loggers.

[Florent Xicluna]

New submission from Florent Xicluna :

Following test case fails with a UnicodeDecodeError:

import logging
import logging.config
logging.getLogger("\xab\xd7\xbb")
logging.getLogger(u"LOG")
logging.config.dictConfig({'version': 1})


Same behavior on "non-ASCII" path buildbots, when test_lib2to3 is run before 
test_logging. It happens because "test_lib2to3" set a logger with key 
u"".
IMHO, it should be fixed in the logging module.

[issue3890] ssl.SSLSocket.recv() implementation may not work with non-blocking sockets

[Antoine Pitrou]

Antoine Pitrou  added the comment:

> The patch seems ok to me. This is how it was supposed to be in the
> first place if ssl.py behaved as expected with non blocking sockets.

Ok, patch applied.

In light of the recv() and recv_into() implementation change, I also
think we should enable SSL_MODE_AUTO_RETRY for SSL sockets. It prevents
blocking read() calls from getting SSL_ERROR_WANT_READ at all.
(previously, we would loop manually in recv() and recv_into(); letting
the C OpenSSL runtime do it for us is certainly more efficient)

See description in
http://www.openssl.org/docs/ssl/SSL_CTX_set_mode.html:

« SSL_MODE_AUTO_RETRY

Never bother the application with retries if the transport is
blocking. If a renegotiation take place during normal operation,
a SSL_read(3) or SSL_write(3) would return with -1 and indicate
the need to retry with SSL_ERROR_WANT_READ. In a non-blocking
environment applications must be prepared to handle incomplete
read/write operations. In a blocking environment, applications
are not always prepared to deal with read/write operations
returning without success report. The flag SSL_MODE_AUTO_RETRY
will cause read/write operations to only return after the
handshake and successful completion. »

The code was added in 2002-07-30 by nnorwitz, to support OSF1 (Dec Unix). Is

It is defined if I add the new "include".

Do we have a list of officially supported?.

Investigating the issue, I could say that HAVE_MAKEDEV should be deleted, but I 
don't have access to a OSF1 machine for trying.

How should I proceed?

[issue8200] logging module errors out if log called when multiprocessing module not finished loading

[Vinay Sajip]

Vinay Sajip  added the comment:

It's structured the way it is for two reasons:
 1. IMO It's better (more readable) to have the simpler case in the "then" 
clause and the more complicated case in the "else" clause.
 2. If multiprocessing is not used, the process name needs to be set anyway to 
"MainProcess". So, I've structured it so the assignment is in just one place.

[issue8108] test_ftplib fails with OpenSSL 0.9.8m

[Antoine Pitrou]

Antoine Pitrou  added the comment:

Ok, I finally agree that test_ftplib should be patched.
The patch isn't exactly correct: it should ideally retry the unwrap() call 
later, rather than simply ignore the error. But since it's just used for 
testing, it looks sufficient.

(we probably lack a higher-level abstraction around ssl sockets, especially 
non-blocking ones; there's too many domain-specific stuff to know for the 
average programmer.)

[issue1069092] segfault on printing nested sequences of None/Ellipsis

[Terry J. Reedy]

Terry J. Reedy  added the comment:

General policy is that ordinary code (not using, for instance, ctypes) should 
not crash or segfault the interpreter.  I believe there is a 'crashers' 
subdirectory somewhere in the tree for examples that do so that people so 
inclined can work on them.

The OP reported a crash on 2.3/2.4a on Linux, but not 1.5. I could not 
reproduce it on 2.2 on Windows. Instead, I (properly) got an exception. Trying 
again with 3.1, I get a similar exception: RuntimeError: maximum recursion 
depth exceeded while getting the repr of a tuple. List instead of tuple does 
similar.

If 
>>> t=None,
>>> for i in range(5): t = t,None

>>> print(t)

still crashes on 2.6/2.7, at least with Linux, then there is still a bug to be 
fixed and the issue should be left open. If it now raises an exception as 
above, then this should be closed as fixed.

I am pretty sure this issue has nothing to do with None and Ellipsis but only 
with the structure (not necessarily a sequence) being deeply, deeply nested. So 
I think the title should be: "Segfault on printing deeply nested structures."

I think the deeper issue is the use of recursion on the C stack to print. If 
the print routine instead usee iteration with an auxiliary Python stack (list), 
then there should be no stack overflow to worry about. [When in increase the 
recursion limit to 10 and try to print the 5 nested tuples, I get 
"MemoryError: stack overflow" instead of the RuntimeError above. So there might 
be more than one fix needed.]

[issue1625] bz2.BZ2File doesn't support multiple streams

[David Bonner]

David Bonner  added the comment:

Picking this back up again.  There's actually no docs changes necessary...the 
docs never mentioned that the module didn't support multiple logical streams, 
and I didn't see any other mentions in the docs that seemed to need updating.  
I supposed I could add something along the lines of "BZ2File supports multiple 
logical streams in a single compressed file", if that's what you/re looking for.

Working on a patch for trunk as well.

[issue8200] logging module errors out if log called when multiprocessing module not finished loading

[Chris Jerdonek]

Chris Jerdonek  added the comment:

Reversing the if-else in Florent's suggestion seems to address points (1) and 
(2).  Is there a reason to set and check an mp variable rather than simply 
having the try-except block?

if not logMultiprocessing:
self.processName = None
else:
# Errors may occur if multiprocessing has not finished loading
# yet - e.g. if a custom import hook causes third-party code
# to run when multiprocessing calls import. See issue 8200
# for an example
try:
self.processName = sys.modules['multiprocessing'].current_process().name
except StandardError:
self.processName = 'MainProcess'

Thanks for the quick action!  I'll try in my dev environment when this is 
settled.

Just that it went over the 80-column limit :-)

Also, I know about asking forgiveness rather than permission, but Florent's 
change doesn't make clear the intent to call current_process only if 
multiprocessing has already been imported (i.e. is in sys.modules). In other 
words, he would catch both the KeyError and any error due to an incomplete 
import of multiprocessing. While either version will work, the way I have it 
preserves the original intent and only traps errors due to multiprocessing 
being incompletely imported.

I don't think so: applications relying on the previous behavior
would need to be updated and requiring this for a patch level
release of Python is not a good idea.

[issue8202] sys.argv[0] and python -m package

[Michael Foord]

New submission from Michael Foord :

When you execute "python -m package" the package is first imported with 
sys.argv[0] set to '-c' (and sys.modules['__main__'] exists but is empty. Then 
package.__main__.py is executed with the correct sys.argv[0].

This means module level code executed during the initial import that attempts 
to work out how the code is being executed can't use either 
sys.modules['__main__'] *or* sys.argv[0].

[issue8108] test_ftplib fails with OpenSSL 0.9.8m

Actually unwrap() should already be called.
What the patch does is returning in case of ERROR_WANT_READ/WRITE, and 
*explicitly avoids to close() the connection when such an event occurs*.

This should grant that another asyncore poll() loop is executed, handle_close() 
automatically be called again and so unwrap().

As I said in comment #100977 I'm not 100% sure of this since I've not been able 
to reproduce the issue. I'm just presuming this as I know that asyncore works 
like this with plain-text sockets.

I'd like to make sure this works as expected even if it's just a test.
If some of the folks able to reproduce this issue could confirm that unwrap() 
gets called again it would be great.

[issue3928] os.mknod missing on Solaris

[Roumen Petrov]

Roumen Petrov  added the comment:

>>> "HAVE_DEVICE_MACROS" is defined if "configure" finds "makedev()" macro.
>> And what is result on you platform ?
>It is defined if I add the new "include".

a) Why you touch test case for "AC_MSG_CHECKING(for major, minor, and makedev)
AC_TRY_LINK([
#if defined(MAJOR_IN_MKDEV)
#include 
#elif defined(MAJOR_IN_SYSMACROS)
#include 
#else
#include 
#endif
],[
  makedev(major(0),minor(0));
],[
  AC_DEFINE(HAVE_DEVICE_MACROS, 1,
[Define to 1 if you have the device macros.])
  AC_MSG_RESULT(yes)
],[
  AC_MSG_RESULT(no)
])"
?
Sorry I did't understand why this test case fail for you.


b) PEP 11 list unsupported platforms and OSF1 is not listed.

c) So code if from revision 27820 that fix "SF patch #584245, get python to 
link on OSF1 (Dec Unix)" . The current patch as is will break OSF1 and other 
OS-es (as example linux don't define this header). Just adding new include will 
fail test case and will left as undefined HAVE_MAKEDEV => mknod won't be added 
for those platforms.

Hmm, the problem here is we don't *know* the module filename until we get hold

import of the package as a side effect.

[Brett Cannon]

Brett Cannon  added the comment:

Nick is right that importing package.__main__ requires importing 
package.__init__ first.

But it sounds like Michael really just wants some way to know when runpy is 
being used over something else. Could a special string token like "" or 
"<-m>" be placed in sys.argv until it is back-patched to what it will 
eventually become? That should allow Michael to find out what whether runpy was 
being used or not.

I don't think this conversion is correct. If there is a test for InstanceType, 
there is (IMO) a fifty-fifty-chance that it is there to distinguish old-style 
and new-style classes, so converting it to object is most likely to break the 
code.

People who actually want this conversion to happen could replace 
types.InstanceType with

  getattr(types, 'InstanceType', object)

or add

try:
  from types import InstanceType
except ImportError:
  InstanceType = object

to the top of the module; this would then work for both 2.x and 3.x (assuming 
that replacing InstanceType with object is actually correct in the code in 
question).

Can't say whether the patch is ok, but I confirm it does fix the issue
here.

[issue8196] sqlit3.paramstyle reported as 'qmark'

[Gerhard Häring]

Gerhard Häring  added the comment:

Thanks for bringing this up.

By changing this we would maybe be a little bit closer to PEP 0249. I don't get 
why the PEP author thinks that 'qmark' is less clear than 'numeric', though. I 
think they're equally clear.

The real reason why I object changing anything here, however, is that by 
changing the paramstyle we would break backwards compatibility. Third-party 
software like ORMs might depend on sqlite3 having paramstyle 'qmark'.

So now someone might suggest to make paramstyle an instance of a subclass of 
string that will successfully compare against both 'qmark' and 'named'. To 
which possible suggestion I say forget it. You cannot anticipate how people 
will really access the paramstyle. And if it would make a difference in 
real-world scenarios.

[issue8206] 2to3 doesn't convert 'types.InstanceType' to 'object'

[Eric Promislow]

Eric Promislow  added the comment:

I'm working on a debugger, trying to identify instances of
old-style classes in Python 2, and any class in Python 3.
The getattr formulation will work, but because I already
need to maintain an "is_v3" flag, I might as well use it
here.

As a side note, how are instances of new-style classes in
v2 categorized?  This v2 code prints 'None':

import types
def get_type_name(target_type):
  for t in dir(types):
if target_type == getattr(types, t):
  return t

class C(object):
  pass

c = C()
print get_type_name(type(c))

[issue8206] 2to3 doesn't convert 'types.InstanceType' to 'object'

[Martin v . Löwis]

Martin v. Löwis  added the comment:

In a sense, *all* objects are instances of new-style classes in 2.x, including 
instances of old-style classes (which are instances of the InstanceType type, 
which is a type, and hence a new-style class).

You may want to look at the __flags__ property of the type object. If it is a 
heap type, there is a good chance that it was created through a class 
statement. Alternatively, you can look at the type's __module__, and find out 
whether the module is a Python module.

[issue8196] sqlit3.paramstyle reported as 'qmark'

[Santiago Gala]

Santiago Gala  added the comment:

I don't think they are equally clear, at least from the point of view of the 
code written towards the API. I think that

execute("UPDATE authors set name = ?, email = ?, comment = ? WHERE id = ?", 
(form.name, form.email, form.text, form.id))

is way less clear, more verbose, and prone to alignment errors, than

execute("UPDATE authors set name = :name, email = :email, comment = :text WHERE 
id = :id", form)

I think this is the reason why the PEP writer prefer named style and. I was 
about to recode an example using a dictionary for cleaner code, when I noticed 
the bug. Now I need to hardcode that sqlite3 supports 'named' style, even if 
paramstyle says other thing, or to dynamically test, in case they decide to 
remove support for the next release. Both are ugly alternatives.
