[issue5345] cStringIO class name typo
Alexandre Vassalotti alexan...@peadrop.com added the comment: This is not a typo. cStringIO.StringIO is a factory function that returns either a cStringO object (for writing) or cStringI (for reading). If this behavior causes a problem to you, then consider using StringIO.StringIO. Alternatively, you could upgrade to Python 2.7 or 3.0 and use io.StringIO() which doesn't have this limitation. -- nosy: +alexandre.vassalotti resolution: - wont fix ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue5345 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue2389] Array pickling exposes internal memory representation of elements
Alexandre Vassalotti alexan...@peadrop.com added the comment: Ah, I just remembered the smart way I had devised some time ago to handle this issue without changing the constructor of array.array. The trick would be to add a __reduce__ method to array.array. This method would return a special constructor function, the binary data of the array and a string representing the format of the array. Upon unpickling, the special constructor function would be called with the binary data and its format and then it would recreate the array. Now, the only thing I am not sure about is whether this would work well with subclasses of array.array. I guess we make __reduce__ also return the instance's type which could be used by special constructor to recreate the instance from the proper subclass. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue2389 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Then the faulty wordwrapping kicks in, and it has to be fixed by removing all the extra spaces and CR by hand. The only way around it that I've found is to use hard CR. But then you have to second guess the right margin. You'll notice that if you undo the wrapping it did on my comment, that the lines are shorter than in your comments! This paragraph was entered w/o returns. It gets screwed as soon as I click outside the widget.

[issue1672568] silent error in email.message.Message.get_payload
Renaud Blanch rndbl...@gmail.com added the comment:
Daniel: i can't remember the exact scenario (i filled this bug 2 years
ago !)
after having a look back at email.message.Message.get_payload, i
remember the problem: the decoding errors are silented by the method and
you have no way to know if the decoding has been successful or not.
to find my malformed email i had to patch the module like that
(basically just removing the try/except blocks):

once again, the behaviour is documented, so it's not really a bug.
but it caused me a lot of trouble (and it does not conforms very well to

but i guess applying such a patch could potentially break number of

[issue5527] multiprocessing won't work with Tkinter (under Linux)
Aki akin...@users.sourceforge.net added the comment: Hello Jani Hakala, Thank you very much for working on the case I created. And, sorry for not getting back to you. I have confirmed observation that the problem is fixed under Linux if Tkinter is imported after fork(). However, this remains a problem for me and most other Tkinter programmers. It is fairy common to import Tkinter using from Tkinter Import *. This is because otherwise all Tk constants need to be prefixed with Tkinter. That is very painful and I don't see such coding except small examples. If I import Tkinter module after fork(), I cannot use from Tkinter *. Therefore this forces programmers to use Tkinter. prefix for every Tk constants. Is there any way to figure out the cause of this problem? Or, is there any way to do from Tkinter import * after fork()? Thank you for your help.

[issue5682] Move io-in-c modules into a subdirectory of Modules/
New submission from Alexandre Vassalotti alexan...@peadrop.com:
Here is a patch that moves the source files of the _io module (and
closely related modules) into subdirectory of Modules. The new file
hierarchy proposed is the following:
Modules/
_io/
_iomodule.h
_iomodule.c
iobase.c
fileio.c
bufferedio.c
textio.c
bytesio.c
stringio.c
I believe that moving the io module into its own subdirectory will make
clear whether the different I/O implementations share common bugs.
Currently, it is quite easy to miss a module when doing a bug fix.
The patch was not tested on Windows. I tried my best to configure by
hand PCbuild and PC/{VC, VS7.1, VS8.0}. However, I would be surprised if
my changes were flawless.

[issue5683] Speed up cPickle's pickling generally
New submission from Collin Winter coll...@gmail.com: This patch simplifies cPickle's complicated internal buffering system. The new version uses a single buffer closer to the Pickler object, flushing to a file object only when necessary. This avoids the overhead of several indirection layers for what are frequently very small writes. Benchmarked against virgin trunk r71058 using perf.py -r -b pickle,pickle_list,pickle_dict: pickle: Min: 2.225 - 1.962: 13.37% faster Avg: 2.254 - 1.994: 13.03% faster Significant (t=70.763434, a=0.95) pickle_dict: Min: 2.097 - 1.418: 47.83% faster Avg: 2.136 - 1.446: 47.75% faster Significant (t=214.900146, a=0.95) pickle_list: Min: 1.128 - 0.777: 45.22% faster Avg: 1.152 - 0.807: 42.65% faster Significant (t=169.789433, a=0.95) A similar patch for unpickling will follow. As issue 5670 and 5671 are committed, I'll update this patch to support them. This patch passes all the tests added in issue 5665. I would recommend reviewing that patch first. I'll port to py3k once this is reviewed for trunk.

R. David Murray rdmur...@bitdance.com added the comment: Is this about correct? Do any test cases need to be updated or added? I notice that something called BytesIO is imported from io but not used. Were some test cases removed which used to involve that class or is that a 2to3 artifact? The set of test cases is almost exactly parallel between 2.7 and 3.1. 3.1 adds an additional DictReader test, and refactors one set of tests to make the code simpler. Other than that, it is just a matter of replacing the file opening and closing code that uses binary mode with 'with' statements where the open uses newline=''. BytesIO is not used so would appear to be a conversion artifact. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4847 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4491] email.Header.decode_header() doesn't work if encoded-word was separeted by CRLF
Tony Nelson tony_nel...@users.sourceforge.net added the comment: See patch in issue1079.

[issue5645] test_memoryio fails for py3k on windows
Hirokazu Yamamoto ocean-c...@m2.ccsnet.ne.jp added the comment:
I'm sure, but with following test code,
def run(module):
print(///)
print(//, module)
memio = module.StringIO(newline=None)
# The C StringIO decodes newlines in write() calls, but the Python
# implementation only does when reading. This function forces them to
# be decoded for testing.
def force_decode():
memio.seek(0)
print(, repr(memio.getvalue()))
memio.seek(0)
print(, repr(memio.read()))
def print_newlines():
print(repr(memio.newlines))
print_newlines() # None
memio.write(a\n)
force_decode()
print_newlines() # \n
memio.write(b\r\n)
force_decode()
print_newlines() # (\n, \r\n)
memio.write(c\rd)
force_decode()
print_newlines() # (\r, \n, \r\n)
def main():
import _pyio, _io
run(_pyio)
run(_io)
if __name__ == '__main__':
main()
//-

///

Maybe universal new line decode behavior is inverse
between _pyio and _io?
That is, _pyio's write() converts '\n' to platform new line, and _io's
write() converts platform new line to '\n'.

[issue1680159] Misleading exception from unicode.__contains__
R. David Murray rdmur...@bitdance.com added the comment: Still gives the same message in 2.7a0. Looks to be simple enough to fix: just stop masking the UnicodeDecode and TypeError messages produced by the PyUnicode_FromObject call in the PyUnicode_Contains method. Test and patch attached.

[issue5527] multiprocessing won't work with Tkinter (under Linux)
Aki akin...@users.sourceforge.net added the comment: Hello Jani Hakala, Thank you for your suggestions. Yes, from Tkconstants import * would ease the pain. The second suggestion, importing gui in another file didn't work well with my code as I'm using a class to host both gui process and non-gui process such that separating gui into another class will create another problem. The first suggestion worked ... almost. I needed to import a bunch of Tkinter related modules in not only gui() but also other call back methods. It solves the problem but the code became pretty messy. It would be nice if the problem is solved so that I don't need to resort to these workarounds. It is a bit frustrating as things work flawlessly under Solaris. I will play around trying to find a bit nicer workaround. Thank you!
