[issue1191964] asynchronous Subprocess
Ross Lagerwall rosslagerw...@gmail.com added the comment: Personally, I would factor out the code for Popen.communicate() in to a Communicator class which wraps a Popen object and has a method communicate(input, timeout=None) - (bytes_written, output, error) How would this differ from the normal communicate()? It seems like there are two different ideas for why people want an asynchronous subprocess: One is that they want to use communicate() but not be limited by memory issues. I think a good API for this case is an asyncore style API or like the one from the patch in issue1260171. Another use case is for an expect-type interface where you read and write based on a timeout or some kind of delimiter like a newline. These should probably be addressed independently.

[issue14879] invalid docs for subprocess exceptions with shell=True
R. David Murray rdmur...@bitdance.com added the comment:
Heh. Maybe what we ought to do is drop the shell argument and make everyone
build their own shell invocations :)
Actually, an API refactor where a shell call looks like this might be kind of
cool:
Popen(shell_cmd('echo magic'))
where shell would return a list.
As for the ValueError, yeah, it's vague, but I think that the only information
that sentence is trying to convey is that ValueError is one of the exceptions
you might get when calling Popen. Exactly what you get it for is pretty much
an implementation detail. If someone wants to grovel through the code and
figure out all the things that can raise ValueError, we could see if there's
any sensible way to turn that into a sentence, but it might not be easy. Short
of that, perhaps we could drop the existing qualifier and just say Popen may
also raise ValueError.

[issue6721] Locks in python standard library should be sanitized on fork
Richard Oudkerk shibt...@gmail.com added the comment: (1) Good catch. I suspect that this could be mitigated even if we cared about LinuxThreads. I haven't looked, but there's got to be a way to determine if we are a thread or a fork child. Using a generation count would probably work just as well as the PID: main process has generation 0, children have generation 1, grandchildren have generation 2, ... (2) I think I didn't explain my idea very well. I don't mean that we should release *all* locks on fork. That will end in disaster, as Charles-François amply explained. So what are you suggesting? That a lock of the default type should raise an error if you try to acquire it when it has been acquired in a previous process? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue6721 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue14775] Dict untracking can result in quadratic dict build-up
stw sil...@googlemail.com added the comment: I had a thought about untracking tuples. If a tuple contains only immutable objects (atomics and tuples of atomics etc), then it should be untracked. Once untracked, it will never need to be tracked again since the tuple is immutable. If a tuple contains mutable objects, it will always need to be tracked. True. However, some tuples may be in an unfinished state (they are being built up internally and a GC collection occurred in the middle). So the tuple is linked-in to the garbage collection list before its contents are constructed? I was wondering whether it is possible to determine whether a tuple needs to be tracked or not the first time it appears in generation 0 - tuples in older generations would then not need to be considered. I'm not sure that would make much of a difference in practice. Most tuples are very short, so checking them for untracking should be reasonably fast. Could tuples not be untracked at creation time then, or do not enough survive to gc to make this worthwhile? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14775 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Amaury Forgeot d'Arc amaur...@gmail.com added the comment: What fails here is the evaluation of x, not the assignment! You are right concerning the assignment, the outer definition has no effect at all. The very presence of x = in the function code turns x into a local variable for the whole function; so 'x + a' fails because the local variable has not value yet. Python, unlike Lisp, defines scopes lexically, not dynamically.

[issue14892] 'import readline' fails when launching with ''

But if I launched it in the following way: python2.X test.py It's stops before finishing the import command (so no output even if I print the output into a file). This doesn't raise any error just stop the program. I tried to add a try...except...finally... but even the finally statement is not executed. Of course, I realize that readline is not that interesting to load with that options. So I would be more than happy if you could indicate me a way to either detect that the user launch the program with '' or a way to avoid readline to stop the program in this situations.

[issue14893] Tutorial: Add function annotation example to function tutorial
New submission from Zachary Ware zachary.w...@gmail.com:
A couple months ago, I had never before heard of function annotations and came
across a function that had them (I don't remember where or what it was). I
spent a fair bit of time searching fruitlessly to figure out what the heck that
- in the function definition meant. Then finally, a week or two ago, I came
across a mention of pep 3107 and function annotations, and figured out what it
was that confused me so thoroughly.
In an effort to save others from the same confusion, I've put together a small
subsection to add to the tutorial about function definition. The text I'm
proposing to add is as follows:
:ref:`Function annotations function` are completely optional,
arbitrary metadata information about user-defined functions. Python itself
currently does not use annotations for anything, so this section is just for
familiarity with the syntax.
Annotations are stored in the :attr:`__annotations__` attribute of the function
as a dictionary and have no effect on any other part of the function. Parameter
annotations are defined by a colon after the parameter name, followed by an
expression evaluating to the value of the annotation. Return annotations are
defined by a literal ``-``, followed by an expression, between the parameter
list and the colon denoting the end of the :keyword:`def` statement. The
following example has a positional argument, a keyword argument, and the return
value annotated with nonsense::
def f(ham: 42, eggs: int = 'spam') - Nothing to see here:
... print(Annotations:, f.__annotations__) # print the function's own
annotations
... print(Arguments:, ham, eggs)
...
f('wonderful')
Annotations: {'eggs': class 'int', 'return': 'Nothing to see here', 'ham':
42}
Arguments: wonderful spam
I'd also like to see a link for - in the index, either to this note or to
the relevant paragraph of compound_stmts.rst or both. The attached patch
attempts to add such a link to this section, but I'm not certain that it's done
properly.
Thanks :)

[issue14744] Use _PyUnicodeWriter API in str.format() internals
STINNER Victor victor.stin...@gmail.com added the comment:
faster-format.patch: Patch for Python 3.3 optimizing str%args and
str.format(args), use _PyUnicodeWriter deeper in formatting. The patch uses
different optimizations:
* if the result is just a string, copy the string by reference, don't copy it
by value. It's not something new, this optimization was already used by the
PyAccu API. Examples:
- {}.format(str)
- %s.format(str)
* avoid a temporary buffer to format integers (base 2, 8, 10, 16). Examples:
- decimal=%s.format(int)
- hex=%x.format(int)
- %o.format(int)
- {}.format(int)
- {:x}.format(int)
* don't overallocate the last argument of a format string. Example:
- x=%s.format(A * 4096)

[issue14892] 'import readline' hangs when launching with '' on BSD and OS X
Ned Deily n...@acm.org added the comment: I took a quick look at this. It's not just OS X, the following also fails on FreeBSD 8.2: $ python2.7 -c 'import readline' $ $ python2.7 -c 'import readline' $ [1] + Stopped (tty output)python2.7 -c ?import readline It seems to be hanging on a read from stdin, as adding a redirect of stdin to /dev/null prevents the hang: $ python2.7 -c 'import readline' /dev/null [1] 36178 $ [1]+ Donepython2.7 -c 'import readline' /dev/null But, on Debian and Ubuntu, neither case hangs. Also, on OS X, the same hang behavior is observed when linked with either GNU readline or BSD libedit.

It works in Python 2.7 so I think it was viewed as a regression.
Python 2.7.3 (default, Apr 20 2012, 22:39:59)
[GCC 4.6.3] on linux2
Type help, copyright, credits or license for more information.
from distutils.version import LooseVersion as v
v('a') v('0')
False
But if 'a' is invalid, then LooseVersion should refuse to accept it in its
constructor, right?

That a lock of the default type should raise an error if you try to acquire it when it has been acquired in a previous process? I was suggesting a way to make 'logging' fork-safe. No more, no less.
