We are discussing backporting working patches, *NOT* having to go through the whole shooting match from scratch. Nevertheless, the task is (usually) far from trivial. Beside the pure functional aspect, you need at least also address testing againt interference with other features, i.e. you need detailed knowledge about Python's test suite and its setup. This obviously is non trivial - as I have seen fixes break other things. If C code is envolved, you need also understand Python's build environment -- another huge requirement of specific knowledge. Especially, because the Python build process must function on many platforms and typical users only use a single one. The first point causes me prefer external packages - where I (not a community) decide about the extent of testing. It is also easy to remove an external package should it really make problems.

As I understand from other messages in this thread, this is also a problem with Python bug fixing. (Not sure who said this, so my apologies if the attribution is incorrect) Bug fixing is not something most programmers find enjoyable, at least not for long durations. I prefer to spend my time solving real world problems, and designing intuitive APIs, this is what brings me joy. This was me. And I am like you. I do not hunt bugs I find in a bug tracker but only bugs I get hit in real world problems. But once hit, I usually find a solution (or work around) and like to share it with others who might get hit in the future. That's why I take the time to file bug reports (often with patches). But when those bug reports and patches seem to be ignored by the core development team - I look for other means, such as external packages. Heck, there have been many times that i purposefully re- invented the wheel simply because solving the problem is much easier (and more enjoyable) than trying to understand another programmer's atrocious spaghetti code. Therefor, we should not be surprised that the bug list is so understaffed and lacks vigor. In my experience (with other open source projects), I think almost none of my patches was ever taken over without modifications. In my view, the changes were usually of a cosmetic nature. For me, this is fine - as long as the problem gets fixed. ... What is becoming apparent to me though, is that most of the complaints i had voiced (years ago) about the exclusive attitudes, horrible interface, and the burdensome workflow of submitting patches is contributing to the lack of interest in this process - and it seems i am not alone! I can remember twice getting excited about helping out, to only quickly become frustrated with the politics and interface. Why should i have to fight just to volunteer? Experience like this (in another project) causes me to be very reluctant to become a core contributor (in the sense of actively fixing things in the core). You need a lot of knowledge (coding conventions, test setup, change workflow, ...) whichs goes far beyond the functionality of the fix -- and you must be resilient, patient and maybe even fighting to get the work accepted. -- https://mail.python.org/mailman/listinfo/python-list

Generating type annotations by tracing execution runs
Hello, I've knocked together a quick proof-of-concept that allows type annotations to be automatically added to Python source code by running it: https://github.com/mwilliamson/farthing As the code, such as a test suite, runs, the types of arguments and return values (for functions in the file/directory to be annotated) are stored. After the code has finished, appropriate annotations are added. (There's a tiny example in the README.rst in case that makes things a little clearer.) At the moment, this is just a small prototype that I've cobbled together. I was curious if anybody knows if anybody else has done anything similar?

A couple of things.
First some core devs are hostile, actually some have stated that
they're simply not interested in 2.7 and will not work on it.
Second how has the thread got here, as it was originally asking about
back porting bug fixes from 3.x to 2.7? Further it said:-

[issue24658] open().write() fails on 2 GB+ data (OS X)
Ronald Oussoren added the comment: This is likely a platform bug, it fails with os.write as well. Interestingly enough file.write works fine on Python 2.7 (which uses stdio), that appearently works around this kernel misfeature. A possible partial workaround is recognise this error in the implementation of os.write and then perform a partial write. Problem is: while write(2) is documented as possibly writing less data than expected most users writing to normal files (as opposed to sockets) probably don’t expect that behavior. On the other hand, os.write already limits writes to INT_MAX on Windows (see _Py_write in Python/fileutils.c) Because of this I’m in favour of adding a simular workaround on OSX (and can provide a patch). BTW. the manpage for write says that writev(2) might fail with EINVAL: [EINVAL] The sum of the iov_len values in the iov array over- flows a 32-bit integer. I wouldn’t be surprised if write(2) is implemented using writev(2) and that this explains the problem.

[issue24646] Python accepts SSL certificate that should be rejected on OSX
Ronald Oussoren added the comment: Using our own OpenSSL build should be saver in the long run anyway. Apple provides enough API’s to reproduce the behaviour of Apple’s build in a cleaner way (by making the loading of system CA certs an explicit action). Problem is: that likely requires using API’s higher up in the API stack, which could cause problems when using os.fork without os.exec (the old “CoreFoundation crashes in child processes” problem).

Ronald Oussoren added the comment: BTW. I think someone (me?) should write down the problems with using higher levels in the API stack w.r.t. os.fork in a PEP-style document. This can then be used to decide whether or not we want to use such APIs in the stdlib (and if so, what should be changed to avoid crashes). I'm slighlty in favour of using such APIs if that makes Python better on OSX, even if that introduces slight differences w.r.t. Linux (for example, multiprocessing could no longer use only os.fork).

Fast 12 bit to 16 bit sample conversion?
I am currently writing a python script to extract samples from old Roland 12
bit sample
disks and save them as 16 bit wav files.
The samples are layouted as follows
0 [S0 bit 11..4] [S0 bit 3..0|S1 bit 3..0] [S1 bit 11..4]
3 [S2 bit 11..4] [S2 bit 3..0|S3 bit 3..0] [S3 bit 11..4]
In other words
sample0=(data[0]4)|(data[1]4)
sample1=(data[2]4)|(data[1] 0x0f)
I use this code for the conversion (using the struct module)
import struct
from array import array
def getWaveData(diskBuffer):
offset=0
words=array('H')
for i in range(len(diskBuffer)/3):
h0=struct.unpack_from('h',diskBuffer,offset)
h1=struct.unpack_from('h',diskBuffer,offset+1)
words.append(h0[0] 0xfff0)
words.append(h1[0] 0xfff0)
offset+=3
return words
I unpack the samples in an array of unsigned shorts for I later can use the
byteswap() method
if the code is running on a big endian machine.
What options using pure python do I have to make the conversion faster?
I thought of unpacking more bytes at once e.g. using a format 'hxhxhxhx' for 4
even samples
and 'xhxhxhxh' for 4 odd samples vice versa.
Can I map the ' 0xfff0' to the whole array?

The patch that I found on internet is only for python 3. Thanks in advance for your answer Best regards *Martine Carannante * Almost certainly no as the patch has never been commited, which is why http://bugs.python.org/issue11588 is till open. Even if the patch were committed there is no guarantee that the patch will be back ported to 2.7. There's almost a guarantee that it will NOT be backported to 2.7, actually; it looks like a completely new feature. But if you're interested, you might be able to apply the patch to a backported argparse, such as: https://pypi.python.org/pypi/argparse Or just patch your own local version, but that's a bit dodgier. If you're willing to migrate your code to Python 3, and you want this feature, post in the tracker issue; even better, help with testing the patch. The patch was updated for Python 3.5 roughly a year ago, and I suspect that that version will still work; the lack of response after that suggests that nobody has the time to test it and make sure it works in all cases. Since argparse is written in Python, you don't even need to play around with a C compiler to test this. It's a nice easy thing to play with - have a shot!

Can I map the ' 0xfff0' to the whole array?
I'll try to read the binary data with numpy.fromfile, reshape the array in

[issue4945] json checks True/False by identity, not boolean value
Mark Mikofski added the comment: This is effecting IronPython as well, because .NET objects return copies not references. If a .NET assembly method is called from IronPython, its return is a copy, not a reference. Therefore the reference of a boolean return is not the same as the internal Python reference for that boolean, and the JSON encoder doesn't recognize the value as a boolean, but instead treats it as an integer, and returns `str(o)`, which for `True` is True and for `False` is False. Then the decoder can't interpret the JSON object because true and false are capitalize, which is not in its spec. :( See my comment https://github.com/IronLanguages/main/issues/1033. The patch would solve this problem. A copy of a boolean will be equal to its value, ie False == False even if their references are not the same. -- nosy: +bwanamarko ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4945 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue24676] Error in pickle using cProfile

cPickle raises a PicklingError when trying to pickle an instance of a class

Example code:

class A(object):

a = A()
with open('file.dat', 'wb') as f:
cPickle.dump(a, f)
Running the above example with python -m cProfile resulted in
cPickle.PicklingError: Can't pickle class '__main__.A': attribute lookup
__main__.A failed
I'm not sure if this is the intended behavior (I suppose __main__ in this case
refers to the cProfile module file), but I googled it and couldn't find
anything. I noticed this problem in Ubuntu 14.04 and Windows 8.1, both with
Python 2.7.

By pure python I'm assuming you mean part of the stdlib.
Referring to https://wiki.python.org/moin/PythonSpeed/PerformanceTips
you could end with something like this (untested).
def getWaveData(diskBuffer):
offset = 0
words = array('H')
wx = words.extend #saves two lookups and a function call
su = struct.unpack_from #saves two lookups
# 'i' not used in the loop so throw it away
for _ in range(len(diskBuffer)/3): # use xrange on Python 2
h0 = su('h',diskBuffer,offset)
h1 = su('h',diskBuffer,offset+1)
wx((h0[0] 0xfff0), (h1[0] 0xfff0)) # MRAB pointed out a
problem with the masking in the second section???
offset += 3
return words
I thought of unpacking more bytes at once e.g. using a format 'hxhxhxhx' for 4
even samples
and 'xhxhxhxh' for 4 odd samples vice versa.
If that reduces the number of times around the loop why not? Combine it
with MRAB's suggestion of lookups and I'd guess you'd get a speedup, but
knowing Python I'm probably way out on that? There's only one way to
find out.
I'm also thinking that you could user one of the itertools functions or
recipes to grab the data and hence simplify the loop even more, but it's
now 3:45 BST, so I can't think straight, hence bed.
Can I map the ' 0xfff0' to the whole array?
If it works :)

Re: Can I copy/paste Python code?

I want to test out the code, and I can copy it, but when I paste it into the Shell, everything is all screwed up because of the indentation. Every time I paste in any kind of code, it seems like everything is immediately left-justified, and then nothing works. Any idea how to make this work easily? Without re-typing hundreds of lines of code... Sounds like a flaw in the PDF - it creates indentation in some way other than leading spaces/tabs. See if the PDF has a corresponding file of ready-to-go code, that might save you some trouble. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
Is there a way to install ALL Python packages?
I'd like to install ALL Python packages on my machine. Even if it takes up 4-5GB, or more, I'd like to get everything, and then use it when I need it. Now, I'd like to import packages, like numpy and pandas, but nothing will install. I figure, if I can just install everything, I can simply use it when I need it, and if I don't need it, then I just won't use it. I know R offers this as an option. I figure Python must allow it too. Any idea how to grab everything? Thanks all. -- https://mail.python.org/mailman/listinfo/python-list

If you want to accept patches and have them acknowledged to their original authors, the patches need to carry metadata identifying the authors. I went to the tracker and hit Random Issue and got one with an attached file as the first hit: http://bugs.python.org/issue12982 http://bugs.python.org/file26008/issue12982.diff Repeated the exercise and won again: http://bugs.python.org/issue4733 http://bugs.python.org/file12437/urlopen_text.diff Notice how the patch files start straight in with content. There's no authorship information retained. By comparison, a patch created with 'git format-patch' and applied with 'git am' starts with RFC 822 headers, provides a commit message, and generally is intended as a way of transmitting a *commit*, rather than simply some changes. I'm not overly familiar with Mercurial workflows, but I think 'hg export' and 'hg import' give the same sort of information; I tried on CPython and got this: # HG changeset patch # User Robert Collins rbtcoll...@hp.com # Date 1436838700 -43200 # Tue Jul 14 13:51:40 2015 +1200 # Branch 3.5 # Node ID 7021d46c490e8d9d3422737c69980dc1602f90db # Parent 0127b0cad5ecb83c39ce58a4be27bf6d43a78d91 Issue #23661: unittest.mock side_effects can now be exceptions again.
