[issue8094] Multiprocessing infinite loop

[Benjamin VENELLE]

New submission from Benjamin VENELLE :

Hi,

The following code results in an infinite loop -->

# 
import multiprocessing

def f(m):
print(m)

p = multiprocessing.Process(target=f, args=('pouet',))
p.start()
# 

I've firstly think about an issue in my code when Python loads this module so 
I've added a "if __name__ == '__main__':" and it works well. But, with the 
following code Python enters in the same infinite loop -->

proc.py:

# 
import multiprocessing

def f(m):
print(m)

class P:
def __init__(self, msg):
self.msg = msg

def start(self):
p = multiprocessing.Process(target=f, args=(self.msg,))
p.start()
# 

my_script.py:
# 
from proc import P

p = P("pouet")
p.start()
# 

It's like Python loads all parent's process memory space before starting 
process which issues in an infinite call to Process.start() ...

[issue8095] test_urllib2 crashes on OS X 10.3 attempting to retrieve network proxy configuration

[Ned Deily]

New submission from Ned Deily :

The current mechanism for urllib and urllib2 on OS X to retrieve network proxy 
information is to call _scproxy.c to query the OS X SystemConfiguration 
Framework.  _scproxy.c uses a schema key, 
kSCPropNetProxiesExcludeSimpleHostnames, that was introduced in OS X 10.4.  
Building on 10.3 results in a compile error.  Current python.org OS X 
installers are built using the 10.4u SDK with a deployment target of 10.3 to 
allow running on OS X 10.3.9.  When such pythons are installed on 10.3, 
attempts to use proxy support, such as is tested in test_urllib2, result in a 
crash:

Exception:  EXC_BAD_ACCESS (0x0001)
Codes:  KERN_PROTECTION_FAILURE (0x0002) at 0x

Thread 0 Crashed:
0   _scproxy.so 0x000a77ac get_proxy_settings + 0x6c

Whether this is worth fixing is debatable, considering that 10.3 has not been 
supported by Apple for many years and that the use of network proxy  servers 
has likely been declining.  At a minimum, it would be better for it to fail 
without a crash but perhaps a README item would suffice.

[issue8095] test_urllib2 crashes on OS X 10.3 attempting to retrieve network proxy configuration

[Ronald Oussoren]

Ronald Oussoren  added the comment:

I don't have a 10.3 system to test on, and definitely don't want to spent 
effort on enabling compiles on 10.3

The patch below would probably fix the crash when running a binary created on 
10.4 or later on osx 10.3:

Index: ../Mac/Modules/_scproxy.c
===
--- ../Mac/Modules/_scproxy.c   (revision 78807)

result = PyDict_New();
if (result == NULL) goto error;
 
-   aNum = CFDictionaryGetValue(proxyDict,

kSCPropNetProxiesExcludeSimpleHostnames);

The patch hasn't been compiled yet, but the idea should be clear: test if 
kSCPropNetProxiesExcludeSimpleHostnames has a valid value before using it, 
default to 'True'.

(This also changes the default on 10.4/10.5, IMHO defaulting to true would be 
better: I haven't seen an enviroment yet where local systems should be accessed 
through a proxy).

BTW. Removing 3.1 and 3.2 because _scproxy isn't in those releases yet (mostly 
because porting requires signifant changes to the C code and I haven't had time 
to do that yet)

[issue8097] bug in modulefinder: import_hook() got an unexpected keyword argument 'level'

[Andreas Pfeiffer]

New submission from Andreas Pfeiffer :

Hi,

  the attached file (moduleFinderBug.py) crashes in python 2.6 on
linux (RedHat EL 5) and Mac OS X (10.6) with the traceback below.

A possible fix for this would be in modulefinder.py:

< self.import_hook(name, caller, level=level)
---
> self.import_hook(name, caller=caller, level=level)

Please let me know if you need any further information.

Thanks,

[issue8083] urllib proxy interface is too limited

[Dominique Leuenberger]

Dominique Leuenberger  added the comment:

I like the idea of having the proxy handler expanded. In fact I suggest to base 
the idea on libproxy ( http://code.google.com/p/libproxy ) which is available 
on Linux / openSolaris / Windows and Mac (currently).

Libproxy queries the correct settings to be used from KDE and gnome, depending 
on the currently running session. A fallback is of course env.

the API of libproxy is very simple and python bindings are available.

[issue8098] PyImport_ImportModuleNoBlock() may solve problems but causes others.

[Graham Dumpleton]

New submission from Graham Dumpleton :

Back in time, the function PyImport_ImportModuleNoBlock() was introduced and 
used in modules such as the time module to supposedly avoid deadlocks when 
using threads. It may well have solved that problem, but only served to cause 
other problems.

To illustrate the problem consider the test code:


import imp
import thread
import time

def run1():
   print 'acquire'
   imp.acquire_lock()
   time.sleep(5)
   imp.release_lock()
   print 'release'

thread.start_new_thread(run1, ())

time.sleep(2)

print 'strptime'
time.strptime("", "")
print 'exit'


The output of running this is


grumpy:~ grahamd$ python noblock.py 
acquire
strptime
Traceback (most recent call last):
  File "noblock.py", line 17, in 
time.strptime("", "")
ImportError: Failed to import _strptime because the import lockis held by 
another thread.


It is bit silly that code executing in one thread could fail because at the 
time that it tries to call time.strptime() a different thread has the global 
import lock.

This problem may not arise in applications which preload all modules, but it 
will where importing of modules is deferred until later within execution of a 
thread and where there may be concurrent threads running doing work that 
requires modules imported by that new C function.

Based on old discussion at:

http://groups.google.com/group/comp.lang.python/browse_frm/thread/dad73ac47b81a744

my expectation is that this issue will be rejected as not being a problem with 
any remedy being pushed to the application developer. Personally I don't agree 
with that and believe that the real solution is to come up with an alternate 
fix for the original deadlock that doesn't introduce this new detrimental 
behaviour. This may entail structural changes to modules such as the time 
module to avoid issue.

Unfortunately since the PyImport_ImportModuleNoBlock() function has been 
introduced, it is starting to be sprinkled like fairy dust across modules in 
the standard library and in third party modules. This is only going to set up 
future problems in multithreaded applications, especially where third party 
module developers don't appreciate what problems they are potentially 
introducing by using this function.

Anyway, not optimistic from what I have seen that this will be changed, so view 
this as a protest against this behaviour. :-)

FWIW, issue in mod_wsgi issue tracker about this is:

http://code.google.com/p/modwsgi/issues/detail?id=177

I have known about this issue since early last year though.

[issue8056] Piped parent's multiprocessing.Process children cannot write to stdout

[Vilnis Termanis]

Vilnis Termanis  added the comment:

I tried to reproduce / narrow-down the cause of this with a debug build in a VM 
but couldn't reproduce the behaviour (neither with debug nor with standard 
2.6.4 binary). I have to conclude that there is something perculiar with my 
native Windows installation (since in both VM and natively Python is using 
exactly the same DLLs and ).

Apologies for wasting your time.

[issue8036] Interpreter crashes on invalid arg to spawnl on Windows

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc  added the comment:

2.6 and 3.0.1 used to disable the Microsoft CRT argument error handler: they 
return EINVAL, but newer versions don't, and should check their arguments 
before calling _spawnv.

FWIW, the checks are::
pathname != NULL
*pathname != '\0'
argv != NULL
*argv != NULL
**argv != '\0'
The first and third checks are guaranteed by the implementation, but the other 
three should be done in posix_spawnv().
And the other calls to the various nt.spawn* functions probably suffer the same 
problem.

[issue8099] IDLE(Python GUI) Doesn't open

[Estroms]

New submission from Estroms :

I downloaded Python 3.1 yesterday. I can open the Python command line, but when 
i press IDLE(Python GUI)shortcut no window or program opens.

i typed to command promt C:\Python31\lib\idlelib\idle.py and got an error 
message. It's too long to write to here, but in the end of it, it said that 
"This probably means that Tcl wasn't installed properly". What should I do?

[issue8093] IDLE processes don't close

[Terry J. Reedy]

Terry J. Reedy  added the comment:

I reproduced this with 3.1.1 on xp. It took a while to get the shell menu to 
restart as the calculation process is hogging the cpu 99%.
KeyboardInterrupt (^C) would not stop the runaway process. There may have been 
other issues about this.

Two processes is normal - one for the shell and one for calculations. The 
'normal' behavior of Restart Shell (^F6) is to start a third process. Watching 
in task manager, the abandoned calculation process dies in 3-4 seconds. A stuck 
process does not end on its own though. Bad bug.

[issue8100] `configure` incorrectly handles empty OPT variable

[Arfrever Frehtes Taifersar Arahesis]

New submission from Arfrever Frehtes Taifersar Arahesis

The comment in configure.in says that some changes aren't applied to OPT 
variable when OPT variable has been set by the user, but they are applied when 
empty OPT has been explicitly set. The attached patch fixes this problem.

[issue8101] w32-shared-ptr.c assertion on Windows 7 with 2.6.4

[issue8103] threading.start() : unable to restart thread

[Benjamin VENELLE]

New submission from Benjamin VENELLE :

Hi,

I've found a bug in threading module. "self._started" event is never cleared 
when thread terminates. So, at line 452, in start() function, the test "if 
self._started.is_set():" prevents any restart.

PS: I saw this bug in Python 3.1.1 32 bit on a Windows 7 platform.

[issue8101] w32-shared-ptr.c assertion on Windows 7 with 2.6.4

[Dave Malcolm]

Dave Malcolm  added the comment:

Perhaps this is an issue in a 3rd-party extension module?  (Given that you're 
running Django, do you have a 3rd-party database connection module?; the last 
message in the log is "Validating models", does that require Django to go to 
the db to get the schema?)

Caveat: I'm not familiar with the Windows msi build of Python, so I could be 
way off here.

[issue6953] readline documenation needs work

[Ronald Oussoren]

Ronald Oussoren  added the comment:

Changing get_history_item to be 0-based would be a backward incompatible change.

The point of my report is that the documentation of the readline documentation 
should mention how the APIs actually behave, you currently have to hunt down 
that information in the documentation from libreadline.

Stefan's message does point to a potentional issue though: history_base is  not 
exposed to python code, and hence Python code cannot use the correct offset.  I 
don't understand the documentation for history_get in that same document 
though, it says "get the item at `offset`, starting from `history_base`". I 
don't understand if that means that `offset` must be at least `history_base` or 
something else (and won't read the readline sources to find out).

[issue8095] test_urllib2 crashes on OS X 10.3 attempting to retrieve network proxy configuration

[Ned Deily]

Ned Deily  added the comment:

OK, I tried the patch.  Reversing the default sense causes the proxy tests in

Unfortunately, it didn't help on 10.3; test_urllib2 still gets a bus error:

[issue8065] Memory leak in readline.get_current_history_length

[Alexander Belopolsky]

Alexander Belopolsky  added the comment:

I my experience, reporting bugs in open source components of OSX to 
bugreport.apple.com is a waste of time.   Such reports are largely ignored  and 
they are not visible to upstream developers.

I believe the upstream for libedit is NetBSD, 
http://cvsweb.netbsd.org/bsdweb.cgi/src/lib/libedit, but I cannot find their 
bug tracker.

I have read the readline source code, and it does mean just that. :-) 

Anyway, this does not really apply to the stdlib because unless someone 
implements 'stifle_history' and friends 'history_base' is going to be 1 at all 
times.

[issue7300] Unicode arguments in str.format()

[STINNER Victor]

STINNER Victor  added the comment:

PyString_Format() uses a "goto unicode;" if a '%c' or '%s' argument is unicode. 
The unicode label converts the partial formatted result (byte string) to 
unicode, and use PyUnicode_Format() to finish to formatting.

I don't think that you can apply the same algorithm here (converts the partial 
result to unicode) because it requires to rewrite the format string: arguments 
can be used twice or more, and used in any order.

Example: "{0} {1}".format("bytes", u"unicode") => switch to unicode occurs at 
result="bytes ", format=" {1}", arguments=(u"unicode"). Converts "bytes " to 
unicode is easy, but the format have to be rewritten in " {0}" or something 
else.

Call trace of str.format(): do_string_format() -> build_string() -> 
output_markup() -> render_field(). The argument type is proceed in 
render_field().

[issue7300] Unicode arguments in str.format()

[STINNER Victor]

STINNER Victor  added the comment:

*Draft* patch fixing the issue: render_field() raises an error if the argument 
is an unicode argument, string_format() catchs this error and converts self to 
unicode and call unicode.format(*args, **kw).

Pseudo-code:

 try:
# self.format() raises an error if any argument is 
# an unicode string)
return self.format(*args,**kw)
 except UnicodeError:
unicode = self.decode(default_encoding)
return unicode.format(*args, **kw)

The patch changes the result type of '{}'.format(u'ascii'): it was str and it 
becomes unicode. The new behaviour is consistent with "%s" % u"ascii" => 
u"ascii" (unicode).

I'm not sure that catching *any* unicode error is a good idea. I think that it 
would be better to use a new exception type dedicated to this issue, but it 
looks complex to define a new exception. I will may do it for the next patch 
version ;-)

[issue7300] Unicode arguments in str.format()

[STINNER Victor]

STINNER Victor  added the comment:

My patch converts the format string to unicode using the default encoding. It's 
inconsistent with str%args: str%args converts str to unicode using the ASCII 
charset (if a least one argument is an unicode string), not the default 
encoding.

>>> "\xff%s" % u'\xe9'
...
UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0: ordinal 
not in range(128)

[issue7267] format method: c presentation type broken

[STINNER Victor]

STINNER Victor  added the comment:

u'{0:c}'.format(256) formatter in implemented in Objects/stringlib/formatter.h 
and this C template is instanciated in... Python/formatter_string.c (and not 
Python/formatter_unicode.c). Extract of formatter_unicode.c comment:

/* don't define FORMAT_LONG, FORMAT_FLOAT, and FORMAT_COMPLEX, since
   we can live with only the string versions of those.  The builtin
   format() will convert them to unicode. */

format_int_or_long_internal() is instanciated (only once) with 
STRINGLIB_CHAR=char and so "numeric_char = (STRINGLIB_CHAR)x;" becomes 
"numeric_char = (char)x;" whereas x is a long in [0; 0x10] (or [0; 0x] 
depending on Python unicode build option).

I think that 'c' format type should have its own function because 
format_int_or_long_internal() gets locale info, compute the number of digits, 
and other things not related to just creating one character from its code 
(chr(code) / unichr(code)). But it's just a remark, it doesn't fix this issue.

To fix this issue, I think that the FORMAT_LONG & cie templates should be 
instanciated twice (str & unicode).

[issue8105] mmap crash on Windows with out of range file descriptor

[Brian Curtin]

New submission from Brian Curtin :

Creating an mmap object can crash the interpreter on Windows if a file 
descriptor is passed in which is outside of the range for _get_osfhandle. I 
noticed the crash possibility while reviewing the Modules/mmapmodule.c code for 
work on another issue related to the consistency of the exceptions which mmap 
raises.

This can be tested by creating a mmap object with the file descriptor for a 
socket. This is not a valid way to create an mmap, but it represents a valid 
file descriptor which is out of range. For example, I created a socket with a 
file descriptor of 124, and _get_osfhandle expects the descriptor to be between 
0 and 23.

Patch against trunk, with a test.

Note that this does not seem to affect 2.6 (not sure why, yet).

[issue8106] SSL session management

[Jesús Cea Avión]

New submission from Jesús Cea Avión :

Current SSL module doesn't manage SSL sessions, so any connection must do the 
full SSL handshake.

SSL/TLS support session restarting, when an old SSL context is used in a new 
connection, so you don't need to do the full SSL handshake.

This is a huge performance improvement.

I think SSL module should keep a small pool of sessions in core, to reuse. 
Better yet:

a) In SSL sockets, a method should be added to get the SSL context.

b) When creating a SSL socket, in client mode, a new optional parameter should 
be accepted, for a SSL context.

c) When creating a SSL socket, in server mode, we have two options: a) provide 
a dictionary or similar, with different contexts for possible clients 
connections or, better b) provide a callback the SSL module will call when 
getting an incoming connection, with a session ID as a parameter. The callback 
can provide a session SSL state or "None". This second approach allow for 
session management, like expiration or persistence to disk.

(the second option is equivalent to the first if the dict-like object includes 
this logic inside)

What do you think?.

[issue2001] Pydoc interactive browsing enhancement

[Ron Adam]

Ron Adam  added the comment:

Missed a buffer write in the gettopic() method. Fixed.
Plus some minor doc string changes.

Can someone change the stage to "patch review".  I can't do that myself.

Or is there something else I need to do first?
