PyCon Posters deadline looms: Nov. 30
The deadline for PyCon poster proposals is coming up soon - November 30! This year PyCon is introducing Poster Sessions. Poster sessions provide an alternative presentation mechanism that facilitates more one-on-one communication between the presenter and the audience. Poster sessions are particularly suited for topics of interest to a subset of the community, and we anticipate these sessions will provide an incubator for further discussions. PyCon 2010 is now seeking proposals for poster presentations and virtual poster presentations. Proposals for posters will be accepted through November 30th, and acceptance notifications will be provided by December 14th. More information about the what, how, when, and why of poster sessions is here: http://us.pycon.org/2010/conference/posters/cfp/ See you at PyCon, -- - Catherine http://catherinedevlin.blogspot.com/ *** PyCon * Feb 17-25, 2010 * Atlanta, GA * us.pycon.org *** -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
Python 3.1 cx_Oracle 5.0.2 ImportError: DLL load failed: The specified module could not be found.
Hello, I'm trying to get Python 3.1 and cx_Oracle 5.02 (cx_Oracle-5.0.2-10g.win32-py3.0.msi) to connect to an Oracle 11.1.0.7.0 database via OraClient10g 10.2.0.3.0 with Pydev 1.5.1.1258496115 in Eclipse 20090920-1017 on Windows XP SP 3 v2002. The import cx_Oracle line appears as an unresolved import and when I run the application I get the following error to console: Traceback (most recent call last): File FILEPATHHERE, line 1, in module import cx_Oracle ImportError: DLL load failed: The specified module could not be found. Apparently the error is caused by cx_Oracle not being able to find the Oracle client DLLs (oci.dll and others). The client home path and the client home path bin directory are in the PATH System Variable and oci.dll is there. I tried getting the Oracle Instant Client (instantclient-basic- win32-11.1.0.7.0.zip from http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/winsoft.html) and installing it as directed. I added the instant client path to the PATH System Variable but that didn't work either. I have scoured the internet and have not found a solution.

Communication between python and wxWidgets.. Help needed...
Hi Friends, I want to thank you all for doing a great job.. I seek your suggestions and valuable guidance regarding two things. 1) I'm using python 3.1.1 and wxWidgets for GUI development in my project .. I want to have a half-duplex communication between widgets and python(say passing something from wxWidgets to python and processing there and sending it back to display the results in widgets). When i googled around i found that we have to have SWIG or Boost::Python and some other third party applications to make this to work.. I'm wondering why it's really tough to establish a communication between the two though wxWidgets which is an excellent tool is mainly projected as a GUI toolkit especially for c++ and python and python is described as a powerful scripting language.. Can u suggest an efficient way by which i could make these two programs to interact(back and forth) easily?? 2) My second question is even if i did that successfully if i want to convert my project into an executable file how would i do that? (Bcoz. i will be having two executables or binaries in linux one for python and other for widgets) Do i need to convert it to lib or dll file with respect to python and c++ or is there any other way for making a build-script? What are the tools and libraries needed(like cx-freeze,pyWin32) to accomplish this?? Please give me some useful links... All of your suggestions are highly welcomed..

Re: non-copy slices
No I'm well aware that there is no deep copy of the objects and the lists only keep references to the objects and in essence they have the same objects in there. But this doesn't mean they are the same list. Modifications to slices are not written back to the original list. x = range(5) y = x[1:3] y[0] = 13 x[1] == y[0] -- False Of course if I modify the object in the slice then the original list will see the change, but this is not what I was saying. Second and more importantly it's the performance penalty from allocating a large number of lists produced from the slices and the copy of the references. islice does not have this penalty, it should only instantiate a small object that iterates on the original list.

Depending on the kind of comparisons you want to do and the sizes of
your input files you could build a dict of dicts.
For example:
def generate_dict_values(F):
column_names = f.readline().split()
for line in F:
row = line.split()
yield row[0], dict(zip(column_names, row[1:]))
# Fake a file.
from StringIO import StringIO
f = StringIO('''\
AA100 AA109 AA101 AA103 AA102
BB1 2 9 2.3 1 28
BB3 12 9 2.3 1 28
BB9 0.5 2 2.3 1 28
BB2 2 9 21 1 20
''')
d = dict(generate_dict_values(f))
# Now you can access the values without regards to the order in the
file like so:
d['BB9']['AA109']
# Pretty print the dict of dicts.
from pprint import pprint
pprint(d)
# Prints:
#
#{'BB1': {'AA100': '2',

Assuming you're talking about optparse, just prefix the number with 0x on the command line: python myscript.py -F 0xDEAD If you don't want to have to type the leading 0x, you'll either have to make yourself a custom type for optparse, or treat it as a string and do the parsing and error handling afterwards.

So every modification you make in this view is actually modifying the original list accordingly. Blist that was suggested in a previous email in the thread seems lightweight but it does create a new list when a modification is made. In any case, I've already implemented the object myself and I can post it if you care to have a look, but I was just wondering if there was already something in the standard library. Themis Unfortunately, I am not very familiar with the stdlib yet (gotta buy that book!). I'm going to guess 'No' since nobody has chimed in with a 'Yes', though. I'd love to see what you have for that. Does in support a stepped window, or only contiguous sequences? The one I put together this afternoon only does contiguous sequences, as I had no use cases to decide how assignments of multiple items should be handled, and not a lot of time to implement something generic -- so, to answer John's question from a completely different thread, yes I do enjoy working on small projects even if IAGNI. :) Cheers! ~Ethan~ -- http://mail.python.org/mailman/listinfo/python-list

[issue7355] Struct incorrectly compiles format strings
New submission from Steve Krenzel sgk...@gmail.com: The struct module has a calcsize() method which reports the size of the data for a specified format string. In some instances, to the best of my knowledge, this is wrong. To repro: from struct import calcsize calcsize(ci) 8 calcsize(ic) 5 The correct answer is 5 (a single byte character and a four byte int take up 5 bytes of space). For some reason when a 'c' is followed by an 'i', this is wrong and instead allocates 4 bytes to the 'c'. This has been verified in 2.6 and 2.5. You can also repro this by using 's', '2c', and similar combinations in place of 'c'. as well as 'I' in place of 'i'. This might effect other combinations as well. -- components: Library (Lib) messages: 95467 nosy: sgk284 severity: normal status: open title: Struct incorrectly compiles format strings type: behavior versions: Python 2.5, Python 2.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7355 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Tom Lynn tl...@users.sourceforge.net added the comment: This bug should be re-opened, since there is definitely a bug here. I think the patch was incorrectly rejected. If I can expand palfrey's example: from textwrap import * T = TextWrapper(replace_whitespace=False, width=75) text = '''\ a a a a a b b b b b c c c c c d d d d d e e e e e''' for line in T.wrap(text): print line Python 2.5 textwrap turns it into: a a a a a b b b b b c c c c c d d d d d e e e e e That can't be right. palfrey's patch leaves the input unchanged, which seems correct to me. I think Guido guessed wrong here: the docs for replace_whitespace say: If true, each whitespace character (as defined by string.whitespace) remaining after tab expansion will be replaced by a single space The text should therefore not be reflowed in this case since replace_whitespace=False. palfrey's patch seems correct to me. It can be made to reflow to the full width by editing palfrey's patch, but that would disagree with the docs and break code. -- nosy: +tlynn ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1859 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue7353] Why was Include/intobject.h removed in 3.1?
Mark Dickinson dicki...@gmail.com added the comment: However, that header file was removed in this commit: http://svn.python.org/view?view=revrevision=71697 Hmm. That was me. with this message: Issue #4910: PyNumber_Int is deprecated in 3.0.1; will be removed in 3.1. That's the message for r69517, I think, which just added an entry to Include/intobject.h. The message for r71697 was: The comments at the top of intobject.h say that it will be removed in 3.1. Make it so. I'm not too sure of the history here, but I suspect that Include/intobject.h was at least partly an aid to porting the Python extension modules from 2.x to 3.0, rather than third-party modules. Christian, Benjamin: any comments? I'm -1 on resurrecting Include/intobject.h in its old location. I don't much like the idea of having a random include file that's no longer used by Python itself in the main Include directory; it'll likely succumb to bitrot before long. But maybe there's a place for 2-to-3 porting aids in the Tools directory, where there's less expectation that files are well-maintained? Is is acceptable if I ship that header file in my distribution packages of python-3.1.1 ? (possibly with a reworded deprecation warning?) I can't see any problem with this.

Because no padding is necessary in the second case: both the integer and the character already start at a position that's a multiple of 4---the integer at position 0 and the character at position 4. In the first case, without padding, the integer wouldn't start at a word boundary. The aim is to make sure that the byte sequence output by struct.pack matches the layout of a corresponding C struct. In the first case inter- item padding is necessary to make that work, in the second it isn't. You could argue that in the second case, Python should add trailing padding, but I'm not sure what the point would be. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7355 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue7355] Struct incorrectly compiles format strings
Mark Dickinson dicki...@gmail.com added the comment:
I'm half-convinced that struct.pack *should* ideally add trailing padding
in the same situation that C does, for consistency with C. Then calcsize
would match C's sizeof. If you're writing or reading a struct from C,
it's probably easiest/most natural to write or read sizeof(my_struct)
bytes, rather than worrying about stripping trailing padding for
efficiency.
I don't see a sensible way to make this change without breaking backwards
compatibility, though.
(Note: this still wouldn't mean that the calcsize result would be
independent of order: calcsize('cci') and calcsize('cic') would still be
different, for example, on a typical platform.)
Eric's solution of adding '0i' should be included in the documentation
update.

[issue7365] grp and pwd should treat uid and gid as unsigned
New submission from Ed Plese e...@edplese.com:
Both Linux and Solaris define uid_t and gid_t as unsigned integers. The
pwd and grp modules cast these to signed long values that are then
converted with PyInt_FromLong. For large values, greater than 2 ** 32 -
1, the result is correct when Python is compiled as a 64-bit executable,
but is incorrect when compiled as a 32-bit executable.
Similar bugs have been noted in the posix module as reported in #4591.
For example, on OpenSolaris build 127, the 32-bit version of Python
returns a negative uid: pw_uid=-2147483647:

The attached patch against 2.6.4 changes PyInt_FromLong to
PyLong_FromUnsignedLong and changes casts to unsigned long.

[issue6594] json C serializer performance tied to structure depth on some systems
Valentin Kuznetsov vkuz...@gmail.com added the comment: Hi, I just found this bug and would like to add my experience with performance of large JSON docs. I have a few JSON docs about 180MB in size which I read from data-services. I use python2.6, run on Linux, 64- bit node w/ 16GB of RAM and 8 core CPU, Intel Xeon 2.33GHz each. I used both json and cjson modules to parse my documents. My observation that the amount of RAM used to parse such docs is about 2GB, which is a way too much. The total time spent about 30 seconds (using cjson). The content of my docs are very mixed, lists, strings, other dicts. I can provide them if it will be required, but it's 200MB :) For comparison, I got the same data in XML and using cElementTree.iterparse I stay w/ 300MB RAM usage per doc, which is really reasonable to me.

Guess I need to be more careful with that possibility. =) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7361 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue7311] Bug on regexp of HTMLParser
Glenn Linderman v+pyt...@g.nevcal.com added the comment: Re: the BTW -- and should be entity-escaped when used in attribute values inside tag attributes... (but are probably seldom found as part of tag attribute values) But the example you showed is not an attribute in a tag, but rather text within a paired tag. But your suggestion for the regexp seems correct to me, if the non-ASCII characters are permitted for non-quoted attribute values. -- nosy: +v+python ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7311 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue7361] Strange importlib error during test_multiprocessing failure
R. David Murray rdmur...@bitdance.com added the comment: This was on a buildbot, and regrtest -j isn't used there, but in any case it wouldn't affect importlib as far as I know. From the traceback it looks like multiprocessing is just doing an import. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7361 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
