[issue4580] slicing of memoryviews when itemsize != 1 is wrong
Nick Coghlan ncogh...@gmail.com added the comment: I still don't see the problem: Py_buffer is a minimal description of a region of memory. No more, no less. It doesn't *do* anything, it's just a description. memoryview is an object that will (when it's finished) provide an easy way to access the memory of another object. Having a fairly raw low level API (Py_buffer/PyObject_GetBuffer/PyBuffer_Release) and a higher level, more convenient, but higher overhead API (memoryview) seems like a perfectly natural split to me. Multi-level APIs are a great way of freeing the more abstract interface from the need to handle every single possible edge case - we can quite reasonably tell people that care about the more obscure edge cases to drop down a level and handle them with the raw API. We just need to finish the job of making the convenience wrapper actually able to handle the task we would like it to handle. Your latest patch goes a long way towards doing that for the 1 dimensional case - if Travis doesn't get to it first, I plan on taking a look a closer look at it this weekend. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4580 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue4580] slicing of memoryviews when itemsize != 1 is wrong
Nick Coghlan ncogh...@gmail.com added the comment: Trying another way of getting the point across... if Py_buffer wasn't defined in PEP 3118, there would have to be some *other* API there whereby the memoryview implementation could ask an object for a description of the data layout of the object's buffer. It is Py_buffer which allows the implementation of memoryview to even be contemplated. The one point where the PEP is silent (and I think this might be what you've been attempting to get at) is as to whether or not it is OK for a client to *modify* the contents of the Py_buffer structure before passing it back in to PyBuffer_Release. And to that I would say that a robust type implementation shouldn't be assuming *anything* about the contents of the Py_buffer passed to PyBuffer_Release. If it needs to do more than decrement a reference count when the buffer is released (e.g. releasing memory allocated for shapes and strides information), then it should be doing its own internal bookkeeping based on the address of the Py_buffer object originally passed to PyObject_GetBuffer. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4580 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

For IDLE specifically I had to disable it. If it fixes a problem with supporting Tcl 8.5, then I will also reject the request. Supporting Tcl 8.5 is a new feature, and should thus not be added to 2.5.3. Only Tcl up to 8.4 is support by Python 2.5. But if it doesn't affect anything in the current usage, why not backport such patch ?

[issue3439] create a numbits() method for int and long types
Raymond Hettinger rhettin...@users.sourceforge.net added the comment:
The code looks fine.
For speed, you could insert the following just before the while-loop:
while (n = 256) {
n = 8;
result += 8;
}
Am not sure the numbits is the right-name. Is there precedent in
other languages or texts on bit-twiddling techniques? For
numbits(0b0100), I could forsee people predicting a result of 4, 3, or 1
depending on their world-view of what numbits might mean. Personally, I
tend to think in term of high-bit location or somesuch.

If I understand correctly, you agree that the SyntaxError is correct as the language is currently defined, but you want the definition changed. It is not clear if you only want implicit deletes at the end of except clauses to work or if you only want explicit deletes to work. If the latter, you want def f(): e = 1 del e def g(): print(e) return g to compile. I would not. Your reason After all, the variable referenced has no value before it is set, (duh, right) makes no sense to me in this context. g must have a valid value of e to run.

If you are saying that the Python command *should* return strings always, then this assumption is precisely a candidate for breakage: people might currently be returning all kinds of things to Tcl in callbacks (even outside Tkinter), and we might break these applications. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4342 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Raymond Hettinger rhettin...@users.sourceforge.net added the comment: Not sure the del e idea was a good solution to the garbage collection problem. Amaury's code looks correct to me. Maybe the existing e variable should be overwritten and the left intact (as it used to be) or perhaps it should be made both temporary and invisible like the induction variable in a list comprehension.

[issue4617] SyntaxError when free variable name is also an exception target
Amaury Forgeot d'Arc amaur...@gmail.com added the comment: Terry, my motivation is that the sample code above runs correctly with python 2.6, but python 3.0 cannot even compile it. The sample looks valid python code, and should run. Yes, the same 'e' is used both as a nested variable and as an exception target, but this should not matter with our dynamic language. First I thought to turn the implicit del e into something else (and change PEP3110), but then I saw that the error can not delete variable referenced in nested scope is actually a limitation of the interpreter that is easy to remove. ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4617 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4617] SyntaxError when free variable name is also an exception target
Phillip J. Eby p...@telecommunity.com added the comment: I could argue either way on this one; it's true that deleting a nested-scope variable is sometimes desirable, but it also seems to me like closing over an except: variable is a Potentially Bad Idea. In neither case, however, do I think it's appropriate to drop the temporary nature of the variable. I could perhaps get behind resetting the variable to None instead of deleting it, but of course the PEP would need changing. There's also a question of whether we should do the same thing with with ... as variables. (Btw, I'm not sure why this one's assigned to me; ISTM I might have proposed the current except/as GC semantics, but I'm not familiar with the actual implementation in 2.6 or 3.0) ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4617 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

It lets me input Japanese and runs commands correctly. So I used gedit and saved a simple print(Hello(in Japanese chars)), and run it with IDLE 3.0 but I get a blank line .

[issue4653] Patch to fix typos for Py3K
New submission from Johnny Lee typo...@gmail.com:
I ran my typo.pl perl script that locates possible C/C++ typos.
I found four that looked valid.
Two of the typos were in the Python directory {pythonrun.c,
dynload_win.c}, two were in PC/bdist_wininst {install.c, extract.c}.
Python/dynload_win.c:
Win32 API FormatMessageW() expects the 6th parameter to be the count of
characters, NOT the count of bytes.
Python/pythonrun.c:
The source code contains if (ferr != NULL || ferr != Py_None). This
does not work as expected - if ferr == NULL, then the second part of
the if expression will succeed. Look at the code handling fout about 8
lines up to see the correct code.
PC/bdist_wininst/extract.c:
Win32 API CreateFileMapping returns NULL on error, not
INVALID_HANDLE_VALUE.
PC/bdist_wininst/install.c:
Win32 API CreateFileMapping returns NULL on error, not
INVALID_HANDLE_VALUE.
