I think this is what went wrong on Windows in the previous test (see
Lib/test/test_cmd_line_script.py:43):
s = '\udcf1\udcea\udcf0\udce8\udcef\udcf2'
f = open(s, w)
f.write(print('%s\\n' % __file__))
f.close()
C:\Users\stefan\pydev\cpythonPCbuild\amd64\python_d.exe ï�
encoding error
So __file__ isn't set correctly, which looks like a bug to me. I'm not sure
whether it should be part of this issue or if we should open a new one.

[issue16218] Python launcher does not support unicode characters
Serhiy Storchaka added the comment:
Andrew, you shod a flea.
1. Now the test skipped on non Cyrillic-compatible locales (such as
en_US.ISO-8859-1).
2. On UTF-8 locale the test does not test the bug (it passed even without the
patch).
Here is a new patch. It should fail on FreeBSD with ASCII locale (because there
is a yet not fixed bug), and I don't know how it will behave on Windows.
Temporary you can explicitly skip the test for such case:
@unittest.skipIf(sys.platform.startswith('freebsd') and
sys.getfilesystemencoding() == 'ascii',
'skip on FreeBSD with ASCII filesystem encoding')

[issue16353] add function to os module for getting path to default shell
Christian Heimes added the comment:
which('sh') isn't correct here. 'which' searches in all PATH environ parts.
However the shell must be looked up in CS_PATH only.
From man sh(1posix):
Applications should note that the standard PATH to the shell cannot be
assumed to be either /bin/sh or /usr/bin/sh, and should be determined by
interrogation of the PATH returned by getconf PATH , ensuring that the
returned pathname is an absolute pathname and not a shell built-in.
'getconf PATH' queries confstr(_CS_PATH).
I suggest that you modify the POSIX part to:
path = os.confstr(CS_PATH)
which('sh', path=path)

In particular, functions are provided which support file copying and removal.

[issue16389] re._compiled_typed's lru_cache causes significant degradation of the mako_v2 bench
mike bayer added the comment: in response to ezio, I poked around the source here, since I've never been sure if re.compile() cached its result or not. It seems to be the case in 2.7 and 3.2 also - 2.7 uses a local caching scheme and 3.2 uses functools.lru_cache, yet we don't see as much of a slowdown with 3.2. so it seems like the caching behavior is precedent here, but I would revert re.py's caching scheme to the one used in 2.7 if the functools.lru_cache can't be sped up very significantly. ideally lru_cache would be native. also does python include any kind of benchmarking unit tests ? over in SQLA we have an approach that fails if the call-counts of various functions, as measured by cProfile, fall outside of a known range. it's caught many issues like these for me. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16389 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16389] re._compiled_typed's lru_cache causes significant degradation of the mako_v2 bench
Nick Coghlan added the comment: Now that Brett has a substantial portion of the benchmark suite running on Py3k, we should see a bit more progress on the PyPy-inspired speed.python.org project (which should make it much easier to catch this kind of regression before it hits a production release). In this case, as I noted in my earlier comment, I think the 3.3 changes to make_key broke an important single-argument fast path that the re module was previously relying on, thus the major degradation in performance on a cache hit. I haven't looked into setting up the benchmark suite on my own machine though, so we won't know for sure until either I get around to doing that, or someone with it already set up tries the change I suggested above. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16389 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15125] argparse: positional arguments containing - in name not handled well
Simon Law added the comment:
But patching the module to allow explicitly setting dest via keyword
argument shouldn't hurt anybody.
I agree that it wouldn't hurt anybody. If you can find a way to do
this, feel free to provide a patch.
However, the correct way to have one name for the attribute (i.e.
dest=) and one name for the help (i.e. metavar=) is to use the
metavar argument like so:
parser.add_argument('positional_args', metavar='positional-args')
I don't think that making ``dest`` more magical is a good idea. In the
included patch, you'll find a change that makes the ValueError tell
people about ``metavar``, which is the right way to go about things
anyway.
That said, this is not the first time I've seen someone run into this
problem. I think the documentation could be improved in a few ways:
(1) In the name or flags section, describe how the flags (for
optional arguments) are translated into both a default dest
(stripping initial '-' and converting '-' to '_') and into a default
metavar (stripping initial '-' and uppercasing). Part of this is
in the dest and metavar documentation, but probably belongs up
in the name or flags documentation. Add cross-references to dest
and metavar sections.
In the included patch.
(2) In the name or flags section, describe how the name (for
positional arguments) are translated into the same default dest
and metavar (no string munging at all). Again, move stuff from the
dest and metavar sections as necessary. Add cross-references to
dest and metavar sections.
(3) In the dest section and somewhere in the parse_args section,
describe how getattr can be used to get attributes whose names
aren't valid Python identifiers. Maybe cross-reference this section
from the edits in (2).
If we make optional and positional arguments consistent, and provide
backwards-compatibility for positional arguments, then these two are
not necesssary.

[issue16397] UserString doesn't combine nicely with strings
New submission from Jorge Cardona:
Hi,
I think UserString must play nicely with other standard objects to be useful.
For example, right now is not possible to join a list of UserString with a
string.
This shouldn't fail:
from UserString import UserString
'.'.join([UserString('some')])
but it fails in 2.7 and it fails too with 3.2 (replacing with collections).
I'm assuming most of the user of UserString, use it as a replacement of a
string, and it would be great to actually be able to replace strings passed to
thid parties with userstrings.
I imagine there would be some edge situations harder to resolve, but if someone
is just using standard libraries it should be safe to pass a string or an
userstring.
Bye.

[issue16394] Improving tee() memory footprint
Carsten Milkau added the comment: No. The sample code is a demonstration how to do it, it's by no means a full-fledged patch. The drawback of the current implementation is that if you tee n-fold, and then advance one of the iterators m times, it fills n queues with m references each, for a total of (n-1)*m references. The documentation explicitly mentions this is unfortunate. I only demonstrate that it is perfectly unnecessary to fill n separate queues, as you can use a single queue and index into it. Instead of storing duplicate references, you can store a counter with each cached item reference. Replacing duplicates by refcounts, it turns (n-1)*m references into 2*m references (half of which being the counters). Not in the demo code: you can improve this further by storing items in iterator-local queues when that iterator is the only one that still needs to return it, and in a shared queue with refcount when there are more of them. That way, you eleminate the overhead of storing (item, 1) instead of item for a fix-cost per-iterator. -- versions: +Python 2.6, Python 2.7, Python 3.1, Python 3.2, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16394 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15125] argparse: positional arguments containing - in name not handled well
Simon Law added the comment: 15125-2.patch applies to the default branch. It makes dest behave the same for positional and optional arguments in terms of name mangling. Also, there is a backward-compatibility path in Namespace to support old-style getattr() access. However, it's not documented as we really don't want people to use it. -- Added file: http://bugs.python.org/file27863/15125-2.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15125 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue14794] slice.indices raises OverflowError
Mark Dickinson added the comment: I should note that this patch fixes/changes one other aspect of slice.indices: namely that it used to accept a negative length, and return essentially meaningless results in that case: slice(0, 10, 1).indices(-3) (-3, -3, 1) With the patch, it now raises ValueError if given a negative length: slice(0, 10, 1).indices(-3) Traceback (most recent call last): File stdin, line 1, in module ValueError: length should not be negative -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14794 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue16398] deque.rotate() could be much faster
New submission from Simon Law: If you look at the implementation of deque.rotate(), it does the equivalent of deque.append(deque.popleft()) or deque.appendleft(deque.pop()). Unfortunately, for larger rotations, the pop() and append() calls just do too much work. Since the documentation recommends using rotate() to do slicing-style operations, this could get seriously slow. deque.rotate() could just touch up the internal pointers and use memmove() to realign the data. Benchmarks, of course, would have to be written to make sure this is a win. -- components: Library (Lib) messages: 174679 nosy: sfllaw priority: normal severity: normal status: open title: deque.rotate() could be much faster type: performance versions: Python 2.7, Python 3.2, Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16398 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue16349] Document whether it's safe to use bytes for struct format string
Mark Dickinson added the comment: but also discovered that example outputs are wrong That's documented to some extent: there's a line in the docs that says: All examples assume a native byte order, size, and alignment with a big-endian machine. Given that little-endian machines are much more common that big-endian these days, it may be worth rewriting the examples for little-endian machines. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16349 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16349] Document whether it's safe to use bytes for struct format string
Mark Dickinson added the comment: Also it would be nice to clarify if struct.Struct.format is meant to be a byte string. Hmm. That seems wrong to me. After all, the format string is supposed to be a piece of human-readable text rather than a collection of bytes. I think it's borderline acceptable to allow a bytes instance to be passed in for the format (practicality beats purity and all that), but I'd say that the output format should definitely be unicode. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16349 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
