[issue15035] array.array of UCS2 values
New submission from Ronald Oussoren ronaldousso...@mac.com:
I'm sometimes using an array.array with format character u as a writable
backing store for buffers shared with platform APIs that access buffers of UCS2
values. This works fine in python 3.2 and earlier with a ucs2 build of python,
but no longer works with python 3.3 because the u character explicitly
selects a UCS4 representation in that version.
An example of how I use this is using PyObjC on MacOSX, for example:
b = array.array('u', hello world)
s = CFStringCreateMutableWithExternalCharactersNoCopy(
None, b, len(b), len(b), kCFAllocatorNull)
s now refers to a mutable Objective-C string that uses b as its backing
store.
It would be nice if there were a format code that would allow me to do this
with Python 3.3, for example b = array.array(U, ...)
(BTW. I'm sorry if this is a duplicate, searching for array.array on the
tracker results in a lot of hits, most of which have nothing to do with the
array module)

[issue12897] Support for iterators in multiprocessing map

[issue8028] self.terminate() from a multiprocessing.Process raises AttributeError exception
Richard Oudkerk shibt...@gmail.com added the comment: One issue with sys.exit() is that it only makes the current thread exit. Even when called in the main thread, the program will wait for non-daemon threads to finish. A closer equivalent to terminate() would be os.kill(os.getpid(), signal.SIGTERM). The problem with minCrashing.py on Windows is that you are inheriting from Queue which has a __reduce__ method. Your Process class is trying to use Queue.__reduce__ to pickle itself. You should really just do self._queue = Queue() instead of inheriting from Queue. -- nosy: +sbt ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue8028 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

John Bollinger john.bollin...@stjude.org added the comment: I attach a patch fixing the issue and providing a test and docs. The fix is substantially as I described earlier: a thread that holds the Tcl lock is permitted to acquire it logically any number of times, but physically attempts to acquire it only if it doesn't already hold it. A thread-local counter ensures that the lock is logically released the same number of times it has been acquired before it is physically released. The external API is unchanged, and even source changes are minimized to the greatest extent possible. If this fix ultimately is accepted then I hope it can also be back-ported to 2.7. -- keywords: +patch Added file: http://bugs.python.org/file25866/reentrant-tkinter.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14390 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

My understanding is you have the copyright by virtue of having published the patch here, and your contributor agreement on file allows us to incorporate it into the codebase, and nothing more is needed.

[issue14390] Tkinter single-threaded deadlock
John Bollinger john.bollin...@stjude.org added the comment: Yes, I have basically made tkinter's Tcl lock into an Rlock. With respect to Python3's Rlock implementation, though, are you talking about what I see in Modules/_threadmodule.c? Even if it would be acceptable to make the tkinter module depend on the thread module (not clear), I don't think I can easily use that because it looks like all the relevant functions are static, in typical extension module fashion. In other words, it provides only a Python API, not a C API. Moreover, the current implementation can easily be backported to Python 2, but that would not be true of an implementation based on the thread module's Rlock. If you would nevertheless prefer that the thread module's Rlock be used then I would appreciate technical suggestions for how to overcome the lack of a C API. I am content to comply with the PSF copyright marking policy. Is it documented somewhere? My understanding is that my copyright does not depend in any way on marking the work -- at least in the US -- but there are other reasons to prefer to mark. Anyway, show me the policy or else just confirm that it is to not mark in cases such as this, and I will remove it. Tkinter threading and re-entrancy issues have been somewhat of a sore spot for a very long time, so I think this change is worth calling out. Nevertheless, if Raymund disagrees then so be it.

[issue15031] Split .pyc parsing from module loading
Brett Cannon br...@python.org added the comment: I point is that it shouldn't break at all if possible, although path_stats does potentially provide a way to deal with this (as does using keyword-only arguments for what needs to be verified). I'll have to think about this. One issue I have with this is I don't love exposing bytecode files too much as people should not typically muck with bytecode files, and if they do they should really know what they are doing. I honestly view them as an implementation detail and not something for people to play with. I also don't want people to get to into bytecode files as they are not necessarily the best way to store bytecode. E.g. a sqlite DB storing bytecode really shouldn't store all of that info in a single column but instead in separate columns and exposing a function as proposed kind of pushes against that idea. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15031 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15038] Optimize python Locks on Windows
New submission from Kristján Valur Jónsson krist...@ccpgames.com: The attached patch does three things: - Abstract the condition variable used by ceval_gil.h into a separate file, condvar.h. It now defines a PyMUTEX_T, PyCOND_T and associated functions. This file can be used by different parts of the python core. - Implement locking on windows using custom structures based on condition variables, rather than using a semaphore kernel object. This avoids kernel transitions for uncontensted locks and provides a large speedup for windows. - Add a condition variable implementation using native primitives for builds targeted for Vista. Experimental and disabled by default. Using this locking mechanism on windows results in a 60% speedup of using uncontested locks, due to the removal of the necessary kernel transition that is required by regular semaphore objects.

I suppose before we see the first bracketed form ({} or {\d+}) we don't know
which it is.

[issue14626] os module: use keyword-only arguments for dir_fd and nofollow to reduce function count
Guido van Rossum gu...@python.org added the comment: I haven't read the code, but from Larry's description this looks great to me. It's amazing how many extra functions were added to the os module since 3.2! I also agree that the redundant functions that existed in 3.2 should stay and I don't see it's fair to deprecate them. I do hope that not too many people have written code based on the 3.3 alphas using all those extra functions, but I suppose they will get what they paid for. Everything else Larry wrote also sounds reasonable to me. -- nosy: +gvanrossum ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14626 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

As in, don't start a deprecation cycle (warning in 3.3, deprecated in 3.4, gone in 3.5), just document consider using this other function instead? That's probably worth doing. I wouldn't use the word deprecated though, I'd just suggest a see also. Maybe we could remove the redundant functions in 4.0.
