[issue7330] PyUnicode_FromFormat segfault
Ray.Allen ysj@gmail.com added the comment: You can write %20s as a argument for PyUnicode_FromFormat(), but it has no effect. The width and precision modifiers are not intended to apply to string formating(%s, %S, %R, %A), only apply to integer(%d, %u, %i, %x). Though you can write %20s, but you cannot write %20S, %20R and %20A. There can be several fixes: 1. make the presence of width and precision modifiers of %s, %S, %R, %A raise an Exception, like ValueError, instead of segment fault. 2. make the presence of width and precision modifiers of %s, %S, %R, %A have no effect, just like current %s. 3. make the presence of width and precision modifiers of %s, %S, %R, %A do have correct effect, like %r and %s in string formatting in python code. Thanks to Eric's ideas. Now I'm sure I prefer the last fix. I will work out a patch for this. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7330 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue8603] Create a bytes version of os.environ and getenvb()

[issue9411] configparser doesn't support specifying encoding in read()
New submission from Łukasz Langa luk...@langa.pl: By default, configparser classes simply `open()` and `read()` files specified in the list passed to `.read()`. This means these calls use the default platform-specific encoding and this is prone to breakage. An existing solution is to use `readfp()` and pass files one by one to it, handling opening them with a specific encoding manually. This is needlessly complex as it increases the amount of boilerplate needed. Please find attached a patch where I've added an `encoding=` argument to the `read()` method. By default it chooses `sys.getdefaultencoding()` so the behaviour is backwards compatible. We might consider switching that to 'UTF-8' but there are many INI files from the Windows land encoded in Windows specific codepages. Anyway, the currently proposed implementation is compatible and enables specifying an `encoding` explicitly. The patch includes a new unit test and some minor fixes for behaviour exposed by this test. -- files: cfgparser.3 messages: 111899 nosy: brian.curtin, ezio.melotti, georg.brandl, lukasz.langa, michael.foord priority: normal severity: normal status: open title: configparser doesn't support specifying encoding in read() Added file: http://bugs.python.org/file18247/cfgparser.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9411 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue9414] infinite loop with specific regexp
New submission from gnuthor ja...@internet24.de:
The follow code hangs on vanilla compile python 2.7 on Ubuntu 10.04 x86_64 and
all other versions of Python that I could find (i386/x86_64, 2.6.5/2.5.2/2.2):
import re
regex = re.compile(r'^((?:\.\d+)+|(?:\.?\w+(?:\-*\w+)+)+)\.(\d*?)$')
match = regex.match('lldpLocChassisIdSubtype')
infinite loop or possibly exponential time
the regex is taken from file client.py of libsnmp-python ( version 5.4.2.1
~dfsg0ubuntu1-0ubuntu2.1 in Ubuntu 10.04 )
libsnmp-python ( 5.4.1~dfsg-12 in Debian Lenny) contains
a previous version of this regex which does not produce an infinite loop
regex = re.compile(r'^((?:\.\d+)+|(?:\.?\w+(?:\-*\w+)+)+)\.?(.*)$')
match = regex.match('lldpLocChassisIdSubtype')
print match
_sre.SRE_Match object at 0x7f5d2abebc68
Perl 5.10.1 can run both of the regular expressions without problems
$ perl -e '$x=lldpLocChassisIdSubtype; print $1 if $x =~
m/^((?:\.\d+)+|(?:\.?\w+(?:\-*\w+)+)+)\.(\d*?)$/;'
$ perl -e '$x=lldpLocChassisIdSubtype; print $1 if $x =~
m/^((?:\.\d+)+|(?:\.?\w+(?:\-*\w+)+)+)\.?(.*)$/;'
lldpLocChassisIdSubtype
I realise that these two regular expression might not particularly sensible and
are certainly not equivalent semantically, but they are syntactically correct,
as far as I can tell, and do not contain back references etc. and thus the
matching process should be able to always
terminate.

[issue7198] Extraneous newlines with csv.writer on Windows
Skip Montanaro s...@pobox.com added the comment: If the documentation is not clear enough about requiring binary, it is a doc bug. The documentation for both csv.reader and csv.writer state (this is from the Python 2.7 version): If *csvfile* is a file object, it must be opened with the 'b' flag on platforms where that makes a difference. I suppose we could be explicit and mention Windows here, but the wording is quite clear. There is really no harm in always opening the file in binary mode, and I do that myself even though I only program on Unix or Mac platforms where it's safe to open the file in text mode. This all changed in Python 3. There, the choice of line ending is up to the programmer, so file objects for use by the csv module are opened with newline='' and when writing CSV data the writer object takes complete control of proper line termination according to the programmer's stated choice of lineterminator.

[issue9405] crash when calling urllib.getproxies() under OSX with subprocess / particular memory usage
Ronald Oussoren ronaldousso...@mac.com added the comment: This seems to be a minimal program to reproduce the problem: import sys import os import platform platform.mac_ver() if sys.version_info[0] == 2: import urllib else: import urllib.request if os.fork() == 0: print (about to call getproxies !) if sys.version_info[0] == 2: print (urllib.getproxies()) else: print (urllib.request.getproxies()) print (getproxies has completed !) else: os.wait() The call to platform.mac_ver is essential, without that call the problem goed away. This explains why my 2.7 build doesn't crash: I've committed a patch at the EuroPython sprints that replaces the platform.mac_ver implementation by one that reads the OSX version from an XML file instead of calling low-level Apple APIs, and those lowlevel APIs somehow cause the breakage (see also issue #7895) This means that the problem should go away in the next release for all branches. mike: are you able to test if the problem goes away when you build python from source using a subversion checkout?

[issue9337] Make float.__str__ behave identically to float.__repr__
Mark Dickinson dicki...@gmail.com added the comment:
A couple of notes on the patch:
- the test_unicodedata failure was a result of computing a checksum involving
str(numeric_value_of_character) for fraction characters like 1/6 and 2/3. I've
changed the test to use '{.12g}'.format(numeric_value) instead, and updated the
checksum.
- the patch changes the result of format(x, ''), so that it continues to match
str(x) when x is a float or complex instance. So when there's no typecode and
no precision given, float formatting behaves like repr/str; when there's no
typecode but a precision *is* given, float formatting behaves like 'g'
formatting, but always ensures at least one digit after the point for a result
in non-scientific format (as before).
This change involves some slightly messy logic in formatter.h (which now needs
to pass type 'r' to PyOS_double_to_string in this case); there may be a better
way to write this code. Eric, if you have a chance to look at the formatter.h
changes, I'd appreciate your comments.

[issue9417] Declaring a class creates circular references
New submission from Andrea Corbellini corbellini.and...@gmail.com: Creating a class (either using the 'class' statement or using type()) creates a circular reference. I've attached a script that simply demonstrates this. The problem is caused by the fact that MyClass.__dict__['__dict__'].__objclass__ is MyClass. Although most of the times classes are never deleted when the interpreted exits, some programs (like the popular Django framework) create temporary classes. And this is a pain because you can't disable the garbage collector. -- components: Interpreter Core files: test.py messages: 111935 nosy: candrea priority: normal severity: normal status: open title: Declaring a class creates circular references type: resource usage versions: Python 2.5, Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3 Added file: http://bugs.python.org/file18251/test.py ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9417 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue9399] Provide a 'print' action for argparse
Steven Bethard steven.beth...@gmail.com added the comment:
Should this print to stdout or stderr? I wonder if the API should allow either,
and instead look like:
parser.add_argument('--license', action='write', message='...', file=sys.stdout)
Where sys.stdout would be the default for the file= argument. The action would
then just literally call file.write(message), so the behavior would be pretty
easy to explain.
Of course, at that point it makes me wonder if maybe it wouldn't just be better
to have an easy way to have some arbitrary function called without having to
subclass Action, e.g.:
parser.add_argument('--license', action='call', callable=lambda:
sys.stdout.write(message))
Basically this would be a shorthand for subclassing Action when you don't need
any information about the command line.

[issue9417] Declaring a class creates circular references
Andrea Corbellini corbellini.and...@gmail.com added the comment: Disabling the GC can increase performances (although not significantly). But this bug is the cause of other problems too: what if the metaclass contains a __del__() method? An another issue that I've found is that debugging is harder. I always try to avoid to create ref cycles in my code, also if my objects are collectable. In this way, I'm sure that I'll always be able to add a __del__ method in the future without problems. However, I can't easily check ref cycles without manually inspecting `gc.garbage`. And also, specifying DEBUG_SAVEALL will put all the deleted classes and their attributes in the garbage, which makes debugging *very* hard in case of a leaking program. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9417 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue9419] RUNSHARED needs LDFLAGS
New submission from Peter Häring p.haer...@gmx.net: test_distutils fails with 2.7 on a shared build (at least if building outside the source tree), 2.6 versions work. The reason for this is, that the test tries to link and doesn't find libpython-2.7.so.1. A solution (or workaround) is to add LDFLAGS=-L`pwd` to the variable RUNSHARED, as I did in the attached file for SUNOS and GNU/Linux etc. Other systems probably need some similar patch. -- components: Build files: Python-2.7-RUNSHARED.patch keywords: patch messages: 111970 nosy: phaering priority: normal severity: normal status: open title: RUNSHARED needs LDFLAGS type: compile error versions: Python 2.7 Added file: http://bugs.python.org/file18255/Python-2.7-RUNSHARED.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9419 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue8603] Create a bytes version of os.environ and getenvb()
STINNER Victor victor.stin...@haypocalc.com added the comment: Le jeudi 29 juillet 2010 03:08:27, Ezio Melotti a écrit : A quick search[0] also shows that environ.data is used by several projects. _Environ is a wrapper on data: call putenv() when a value is changed and unputenv() when a value is removed. Since os.environb, it does also convert key and value types. So .data should not be used directly. It looks like a common usage of .data is to get get to a real dict (and not an user dict). I think that os.environ.data or os.environ.data.copy() can be replaced by dict(os.environ) is that case. Changing it from str to bytes will most likely break these programs, I'm not sure of that. It looks (in the search result) that os.environ.data is just stored and passed to a function, but not used as a dictionary to get a value (well, I'm not sure because it's hard to say with just 3 lines of the program). In that case, it doesn't matter if the dictionary contains byte or unicode strings. Eg. zope2instance: old_env = os.environ.data.copy() ... os.environ.data = old_env It does still work with bytes. so I'm not sure it's a good idea Yes, it's not a good idea to use .data :-) This attribute should be protected, not public (even if it is not documented). IMHO os.environ.data should contain str, whereas os.environb.data bytes. data is shared between os.environ and os.environb, because data is the solution to synchronize both dictionaries. If they must share the same data I would prefer them to be both str. No, data should use the native type: bytes on UNIX and BSD, str on Windows. -- If you still consider that the change on .data as a bug, I think that the fix is to remove .data (mark it as protected: environ.data = environ._data). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8603 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue9404] IDLE won't launch on XP
Chris Leaf xcyborgni...@gmail.com added the comment: I solved the problem myself by editing the EditorWindow.py file where it sets self.recent_files_path by setting it to a different file location (I created a file in my Python31 directory named recent-files.lst and then set the recent_files_path to the absolute path to this file I made). This seems to be working so far and works like a complete work around the .idlerc folder issue.

[issue9420] gdbm with /usr/include/ndbm.h
New submission from Peter Häring p.haer...@gmx.net: There are systems out there, wich don't have ndbm, but gdbm and ndbm.h directly in the include-path (usually /usr/include), not in the subdirectory i.e. gdbm. setup.py at the moment assumes, that there is ndbm on the system, if there is ndbm.h in the include path. If it doesn't find libndbm, it continues to try to use ndbm without library, which doesn't work. BLFS (http://www.linuxfromscratch.org/blfs/view/svn/general/python.html) fills in the gdbm and gdbm-compat library, which works, but is wrong, because we really use gdbm and not ndbm. The right way is to start with the library change and then look for the header file, as it is in the proposed patch for setup.py -- components: Build files: Python-2.7-gdbm.patch keywords: patch messages: 111978 nosy: phaering priority: normal severity: normal status: open title: gdbm with /usr/include/ndbm.h versions: Python 2.7 Added file: http://bugs.python.org/file18256/Python-2.7-gdbm.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue9420 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
