[issue5135] Expose simplegeneric function in functools module

[Paul Moore]

Paul Moore  added the comment:

Well spotted! I missed that when I checked. I will add tests and
documentation.

I agree that generic is better. I only left it as it was because the
original intent was simply to move the existing code - but that's not a
particularly good reason for keeping a clumsy name. There shouldn't be a
clash, as any more general mechanism can either be in its own module or
the existing function can be extended in a compatible manner. I'll make
this change too.

Thanks for the feedback!

[issue5150] IDLE to support reindent.py

[Raymond Hettinger]

New submission from Raymond Hettinger :

Add rstrip() to the Format menu.

Python's svn repository no longer accepts files with trailing whitespace
and it is often necessary to run reindent.py before submitting.  It
would be nice to have this as a built-in formatting tool.

[issue5128] compileall: consider ctime

[Martin von Gagern]

Martin von Gagern  added the comment:

Not being a regular Python programmer myself, I've never even heard of a
context manager before, but this latest patch should fit the bill.

As for tests, I believe that a few two-second sleeps (as FAT has only
two second resolution iirc) should avoid the kind of problem you
describe. This latest patch includes unit tests, where the test_backdate
fails for current implementation. The others are there to express even
more basic assumptions, and can be dropped if you worry about those
seconds spent running obvious tests. The tests are based on
test_dircache, from which I copied and adapted the infrastructure for
dealing with a temporary directory.

[issue5139] Add combinatoric counting functions to the math module.

[Mark Dickinson]

Mark Dickinson  added the comment:

> I suggested to include math.npermutations_with_repetitions for
> completeness,

Ezio, itertools currently has combinations with and without *replacement*, not 
repetition.  I think 
you're talking about something slightly different (repetitions in the 
*iterable*, rather than allowing 
repeated *drawings* of the same element).  itertools already has 
'permutations_with_replacement':  it's 
called 'product'.

combinations(it, r): select r elements from it, no replacement, no order
permutations(it, r): select r elements, no replacement, order is relevant
combinations_with_replacement(it, r): replacement, no order
product(it, repeat=r): replacement, order

[issue5109] array.array constructor very slow when passed an array object.

[Malcolm Purvis]

Malcolm Purvis  added the comment:

It's true that memcpy won't work when the data type changes, but I would
assume (with no evidence to back me up) that the most common case for
passing an array into the array's constructor would be when data types
are the same.  That case would be case to detect especially and use
memcpy for.

[issue5135] Expose simplegeneric function in functools module

[Nick Coghlan]

Nick Coghlan  added the comment:

The reason I like the simplegeneric name is that that is exactly what
this feature is: a *simple* generic implementation that is deliberately
limited to dispatching on the first argument (because that is easily
explained to users that are already familiar with OOP and especially the
existing Python magic method dispatch mechanism.

So the name isn't just about avoiding name clashes, it's also about
setting appropriate expectations as to what is supported. Yes, the name
is a little clumsy but one thing I do *not* want to see happen is a
swathe of feature requests asking that this become an all-singing
all-dancing generic function mechanism like RuleDispatch.

Don't forget that actually *writing* generic functions (i.e. using the
@functools.simplegeneric decorator itself) should be far less common
than using the .register() method of existing generic functions.

[issue5135] Expose simplegeneric function in functools module

[Paul Moore]

Paul Moore  added the comment:

Fair comment. As Ryan said, it's a bit of a bikeshed issue. I prefer
"generic", on the basis that I'd prefer to keep the simple name for the
simple use - something as complex as the RuleDispatch version could use
the name "dispatch" (if they want to keep it the name simple) or
"multimethod" (to emphasize that it dispatches on more than just one
argument).

If the consensus is for keeping it as "simplegeneric", I'll go with
that, but I'll wait for other views first.

BTW, another option is simply to clarify the limitations in the
documentation. I can add something there if that would be enough for you.

[issue4285] Use a named tuple for sys.version_info

[Eric Smith]

Eric Smith  added the comment:

The doc string for sys includes:
version_info -- version information as a tuple

I'm not sure changing this to "... as a structseq" makes it any more
useful, but it's more correct. Does anyone have a preference? I'd use
the same wording as float_info, but that's missing from the doc string
(and I'll deal with that as a separate issue).

Other than that, this all looks good to me. I also tested that the docs
build. I'll check it in once I get or invent new wording for the doc string.

[issue5151] extractall method for TarFile objects not setting owner:group on directories

[Nicholas Patterson]

New submission from Nicholas Patterson :

Used the TarFile object to create a bzip2 compressed tar file (seems to
have worked fine).  Then used the extractall method to restore the
archive in a new location.  All the files appear to have the same
permissions and owner:group as before, but most of the directories
('state' is only exception) have different permissions and the
owner:group are set to the UID that was running the script in this case
root:root.

Antoine Pitrou  added the comment:

Probably it has already been said, but for the record: is ipaddr's
current API ok for other libraries (mainly: netaddr) to build upon it
and provide compatible extensions or replacements, or would netaddr
become an incompatible alternative to the stdlib-provided ipaddr? The
latter would be a shame.

[issue3959] Add Google's ipaddr.py to the stdlib

[Duncan McGreggor]

Duncan McGreggor  added the comment:

Antione,

We're (netaddr) going to try to use ipaddr if possible, but there are 
operations which we are providing to API users that aren't directly
supported by ipaddr. We haven't yet determined the level of effort
involved in trying to work with ipaddr's base classes in supporting
these, but it may be more effort (and code) than it's worth (the
benefits of using ipaddr may be lost).

In a sense, it would be a shame. But on the other hand, we have examples
where 3-rd party web frameworks don't use the built-in HTTP server, and
that hasn't been a problem. In many ways, netaddr is evolving into an IP
manipulation framework. Those that need its features can use it; those
that just need the basics will be able to get that in the stdlib.

In any case, it will be in our best interest to provide some
compatibility layer between the two :-)

FWIW, I put an alternative in the sandbox /dbm_sqlite/alt/dbdict.py and

delay all writes until closing.  That lets us subclass from dict and get
high-speed lookups, sets, and deletions.  Freeing ourselves from an DB
also gets us a choice of ultra-portable file formats (json, csv, pickle,
eval).

[issue5135] Expose simplegeneric function in functools module

[Walter Dörwald]

Walter Dörwald  added the comment:

The patch looks fine to me. Tests pass.

I have no opinion about the name. Both "simplegeneric" and "generic" are
OK to me.

I wonder if being able to use register() directly instead of as a
decorator should be dropped.

Also IMHO the Python 2.3 backwards compatibility (__name__ isn't
setable) can be dropped.

[issue5152] Add a JSON-RPC module

[Martin v. Löwis]

Martin v. Löwis  added the comment:

I think this feature request is out of scope for this bug tracker. To
fulfill the request, one not only has to *add* the module, but to
*implement* it first.

Since there is no inherent need for such a module to be provided with
the standard library, somebody implementing it should well first publish
it on PyPI, build a community, have it used for some time, and then
propose it for inclusion (e.g. through this bug tracker). That's the
same route that the XML-RPC implementation took.

If nobody volunteers to implement such a module, chances are high that
it is because nobody actually needs a Python implementation of a
JSON-RPC client module.

[issue5154] OSX broken poll testing doesn't work

[Ben Bangert]

New submission from Ben Bangert :

OSX 10.5 has a broken poll, this is an already known issue as I noticed
there's even a HAVE_BROKEN_POLL option that is in the source:
http://mail.python.org/pipermail/python-checkins/2006-April/051710.html

However, this run-time check apparently does not work, as I continue to
get socket errors related to the broken poll (On *any* version of Python
I compile from 2.4 through 2.6) unless I recompile Python and manually
comment out HAVE_POLL like the first line of Apple's Python patch here:
http://www.opensource.apple.com/darwinsource/10.5.6/python-30.1.2/fix/pyconfig.ed

Further, I think its quite likely that other bugs being submitted all
over the place from users running MacPorts on OSX are misdiagnosing this
bug as they believe its related to other software, when it is in fact
specific to custom compiles (MacPorts included) of Python. This bug
usually manifests itself as a Socket 35 error like so:
http://bugs.python.org/issue1085
http://www.cherrypy.org/ticket/598

This issue was diagnosed for me by Phil Jenvey, who believes that all
versions of OSX to date have had a broken poll (which reflects my paste
experience with this socket 35 bug as well).

I'm not sure of the most appropriate fix, I've submitted a bug to
MacPorts as well with the recommendation that for now they apply a patch
to undef HAVE_POLL, as Apple does.

[issue4285] Use a named tuple for sys.version_info

[Raymond Hettinger]

Raymond Hettinger  added the comment:

> Eric Smith  added the comment:
> "... as a named tuple" works for me. I'll go with that. Thanks!

+1 

Remember, "named tuple" is a concept, not a class.  It is anything that
provides attribute access as an alternative to indexed access (see the
definition in the glossary where time.struct_time is given as an
example).  Running the collections.named_tuple() factory function
creates a new class with named tuple features, but it is just one of
several ways of creating named tuples.

That's not a sufficient reason to copy their work-around. A problem must

[issue5135] Expose simplegeneric function in functools module

[Paul Moore]

Paul Moore  added the comment:

Agreed about the compatibility. It's there from pkgutil, where to be
honest, it's even less necessary, as simplegeneric was for internal use
only, there. I'm certainly not aware of any backward compatibility
requirements for functools.

Assuming nobody speaks up to the contrary, I'll rip out the
compatibility bits in the next version of the patch.

I'm unsure about the non-decorator version of register. I can imagine
use cases for it - consider pprint, for example, where you might want to
register str as the overload for your particular type. But it's not a
big deal either way.

Ah, sorry, misunderstanding. I'm not recommending that Python copy

Python done on OSX will suffer this socket 35 error without having
HAVE_POLL commented out.

As I mention in the original message, I'm not sure of the most

[issue691291] codecs.open(filename, 'U', 'UTF-16') corrupts text

[And Clover]

And Clover  added the comment:

> The problem is that codecs.open() forces binary mode on the underlying
file object, and this defeats the U mode.

Actually the problem is it doesn't defeat it!

The function is documented to force binary, but it actually only does
"mode = mode + 'b'", which can leave you with a mode of 'rUb'. This mode
should be invalid but in practice the 'U' wins out, and causes the
expected problems for UTF-16 and some East Asian codecs.

Until such time as text/universal mode is supported at the overlying
decoded stream level, I suggest that 'U' should be .replace()d out of
the mode as well as 'b' being added, as the documentation would imply.

[issue5155] Multiprocessing.Queue created by subprocess fails when used in sub-sub-process

[Beau Butler]

New submission from Beau Butler :

(Note: This issue only happens on linux - on Windows things work fine.)

Please see the attached script.

The script creates a process (TestProcess()). That process runs and
creates a sub-process (TestSubProcess()). When TestSubProcess tries to
access a Queue created by TestProcess, the .get() call fails with the
following stack trace:

Process Process-1:1:
Traceback (most recent call last):
  File "/opt/python2.6/lib/python2.6/multiprocessing/process.py", line
231, in _bootstrap
self.run()
  File "/opt/python2.6/lib/python2.6/multiprocessing/process.py", line
88, in run
self._target(*self._args, **self._kwargs)
  File "queue_test.py", line 7, in TestSubProcess
item = q.get()# Fails with IOError if queue
created in TestProcess
  File "/opt/python2.6/lib/python2.6/multiprocessing/queues.py", line
91, in get
res = self._recv()
IOError: [Errno 9] Bad file descriptor

If the same queue is created by main (top level), TestSubProcess
accesses it with no errors. This behavior can be stimulated by
uncommenting the q = multiprocessing.Queue() line in TestProcess.


Tested using:
Python 2.6.1 (r261:67517, Dec  4 2008, 16:51:00) [MSC v.1500 32 bit
(Intel)] on win32
(Installed using binary installer, windows XPSP2)

*No problems*

Python 2.6.1 (r261:67515, Jan  6 2009, 15:23:19) [GCC 4.2.4 (Ubuntu

(Compiled from source due to ubuntu 8.04 (Hardy) not having python2.6 yet)

[issue5135] Expose simplegeneric function in functools module

[Ryan Freckleton]

Ryan Freckleton  added the comment:

I think that registering existing functions is an important use case, so
I vote for keeping the non-decorator version of register.

Another thing that we may want to document is that [simple]generic
doesn't dispatch based on registered abstract base classes.

>>> class A:
... pass
...
>>> class C:
... __metaclass__ = abc.ABCMeta
...
>>> C.register(A)
>>> @generic
... def pprint(obj):
... print str(obj)
...
>>> @pprint.register(C)
... def pprint_C(obj):
... print "Charlie", obj
...
>>> pprint(C())
Charlie <__main__.C object at 0xb7c5336c>
