[issue7980] time.strptime not thread safe
Carlos Corbacho cathec...@gmail.com added the comment: As per my comments on Issue11108 - I suspect that PyImport_ImportModuleNoBlock is a bit of a red herring here - in Python 2.5 and earlier versions (well before PyImport_ImportModuleNoBlock was added), we have occasionally seen 'AttributeError: strptime' from threaded code calling time.strptime(), so whatever this bug is, I don't believe it's caused by the call now being non-blocking from 2.6 onwards. -- nosy: +ccorbacho ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7980 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue10994] implementation details in sys module
Martin v. Löwis mar...@v.loewis.de added the comment: I can propose a specification of getsizeof: if you somehow manage to traverse all objects (without considering an object twice), and sum up the getsizeof results, you should end up with something close to, but smaller than the actual memory consumption. How close is a quality-of-implementation issue (so always returning 0 would be correct-but-useless). It may be that implementations can also support counting certain hidden memory usage (headers, blocks shared across instances that are not objects themselves). Such functions would should have different names and interfaces (e.g. sys.gethiddenblocks(o) may return a list of (address, size) pairs); CPython doesn't provide any such function (although sys.mallocoverhead might be useful). In any case: I'm not convinced that it is useful to mark functions as CPython-specific in the documentation. This clutters the documentation, and is of interest only for language lawyers. So if implementation details are to be documented, I'd prefer this to happen in a separate document. -- nosy: +loewis ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10994 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

I agree that it's not really useful to mark functions as CPython-specific in the documentation, if only because whenever a new implementation like PyPy comes along, then it's going to have a rather different set of functions that it wants to consider implementation details. I would say that more than half the functions in the sys module marked CPython-specific in the doc are implemented in PyPy just fine, and there is an equal number of functions not marked CPython-specific that have no chance to be implemented in PyPy. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue10994 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11114] TextIOWrapper.tell extremely slow
Laurens 3.14159265...@xs4all.nl added the comment: First of all, thanks to all for your cooperation, it is very much appreciated. I made some minor changes to the benchmark program. Conclusions are: * setting file._CHUNK_SIZE to 20 has a dramatic effect, changing execution time in 3.2rc2 from 8.4s to 0.06s, so more than a factor 100 improvement. It's a bit clumsy, but acceptable as a performance work around. * opening file binary has a dramatic effect as well, I would say. After 2 minutes I stopped execution of the program, concluding that this change made the program at least a factor 10 *slower* instead of faster. So I cannot confirm DSM's statement that the performance hit would be a factor 2. Instead, I see a performance hit of at least a factor 10 (10e5) compared tot 2.7.1, which is presumably not by construction ;-). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11076] Iterable argparse Namespace
Éric Araujo mer...@netwok.org added the comment: Nice idea indeed, thanks for the patch. For the doc section, I’d prefer to de-emplasize the specific use case of **kwargs, in favor of mentioning dict conversion in a general way: Converting the namespace to a dict ^^ Namespace objects are iterable so you can easily convert them to a :class:`dict`:: args = parser.parse_args() argdict = dict(args) This makes it easy to introspect the namespace or to pass the command-line arguments to a function taking a bunch of keyword arguments:: somefunction(**dict(parser.parse_args())) +def __iter__(self): +return iter(self.__dict__.items()) Isn’t “return self.__dict__.items()” sufficient in 3.x? Alternate idea: don’t implement __iter__, which is sorta too broad, and implement a method that just returns a dict. Musing: Isn’t Namespace (technically: _AttributeHolder) very much like a named tuple? Could some code be removed by using named tuples in argparse? Note that named tuples provide a method to convert themselves to a dict, and are efficient (IIRC). -- nosy: +bethard, eric.araujo stage: - patch review ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11076 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue11119] Passing a socket to a process (multiprocessing module)
New submission from pen hill imbenh...@gmail.com:
When I run the following listing (server_multi.py) by using multiprocessing
module of python, it runs successfully on a Linux machine. However, on a 64-bit
windows machine I get the following error:
pickle.PicklingError: Can't pickle built-in method recvfrom_into of
_socket.socket object at 0x02D2CF10: it's not found as
__main__.recvfrom_into
This module is from the book Foundations of Python Network Programming, 2nd
Edition. I am pasting the code with the permission of the author. It seems that
socket listen_sock cannot be pickled under 64-bit
Windows, however it can be pickled under Linux. How can we remove this issue on
Windows? It is interesting that if I use the threading module, it works for
both Windows and Linux. Thanks.

[issue11123] problem with packaged dependency extracter script, pdeps
New submission from $$Coffeepot$$ coffeepott...@yahoo.com:
This bug concerns the pdeps script, python directory\Tools\Scripts\pdeps.py.
This script opens a list of files and extracts a list of their
inter-dependencies.
I'm running Python 3.1.1 on Windows XP, installed via binary installer, but
have confirmed that the bug is present in the source distribution of Python 3.2
rc2, the newest code I know of. (In fact, the only difference between the
pdeps.py files in each version was the shebang line, 3.2 rc2 shebang line: #!
/usr/bin/env python3, 3.1.1 shebang line: #! /usr/bin/env python.)
When I tried out the module I found a series of small bugs, basically typos,
each of which caused the script to crash due to an unhandled exception.
1.
The relevant section of the unmodified pdeps.py file
# Compiled regular expressions to search for import statements
#
m_import = re.compile('^[ \t]*from[ \t]+([^ \t]+)[ \t]+')
m_from = re.compile('^[ \t]*import[ \t]+([^#]+)')
# Collect data from one file
#
def process(filename, table):
...
if m_import.match(line) = 0:
(a, b), (a1, b1) = m_import.regs[:2]
elif m_from.match(line) = 0:
(a, b), (a1, b1) = m_from.regs[:2]
...
The match method of a compiled regular expression returns an SREMatch object,
so the conditionals must be changed. In addition, the regs data is a member of
the match object itself, not the compiled expression object, so the right side
of the assignments must also be changed.
modified version
...
import_match = m_import.match(line)
from_match = m_from.match(line)
if import_match:
(a, b), (a1, b1) = import_match.regs[:2]
elif from_match:
(a, b), (a1, b1) = from_match.regs[:2]
...
2.

# Invert a table (this is again totally general).
# All keys of the original table are made keys of the inverse,
# so there may be empty lists in the inverse.
#
def inverse(table):
inv = {}
for key in table.keys():
if not inv.has_key(key):
inv[key] = []
for item in table[key]:
store(inv, item, key)
return inv
Dictionaries have no has_key method, though I vaguely recall that they used to.
That's a quick fix though.

for key in table.keys():
if not inv.has_key(key):
inv[key] = []
* PDEPS.PY
for key in table.keys():
if key in inv:
inv[key] = []
*
With these changes the pdep script works as expected.
This is a pretty lower priority bug imho. It prevents anyone from using the
script, but fixing the bug took about 5 minutes, and I doubt the pdeps script
gets much use anyway. This bug is unlikely to inconvenience anyone.

[issue11122] bdist_rpm fails
Eric Smith e...@trueblade.com added the comment: rpm -ba is very old. I think it's been at least since 2002 that -ba was supported by rpm. I believe bdist_rpm is calling rpmbuild -ba, and if that doesn't exist, then rpm -ba is a transition strategy until all systems supported rpmbuild. This transition period should be over. Unfortunately today it's far more likely that rpm -ba will not be what you want to call, but rpm will almost always be found, giving this error. Most systems (certain RedHat based) ship rpmbuild as a separate command. RedHat installs it via the rpm-build package. I'd suggest just switching bdist_rpm to always use rpmbuild. Then at least the error would be that rpmbuild isn't found. -- nosy: +eric.smith ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11122 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
