Maybe we can try and explore the reference graph again? This sort of thing is one of the reasons that the cycle GC does not call any finalisers. Attempting to do finalisation during deallocation is asking for trouble, and it seems to be pervasive in CPython. I'm surprised this sort of bug is not more common.

[issue13540] Document the Action API in argparse
Steven Bethard steven.beth...@gmail.com added the comment: Sorry about being out of contact (I'm flying back and forth between the US and the EU every 4-5 weeks right now), and thanks Terry for bringing this to my attention. Essentially, the API is: * The argument to action= must be a callable that accepts at least a dest and option_strings keyword arguments, and returns some object. The keyword arguments passed to this callable will be dest, option_strings, and whatever other keyword arguments were passed to add_argument(). * The object returned by the action= callable should have attributes dest, option_strings, default, type, required, help, etc. defined in essentially the same way as the add_argument() documentation. * The object returned by the action= callable should itself be callable, and should accept the arguments (self, parser, namespace, values, option_string=None). This method can do whatever it wants, but as you note, the typical approach is to invoke setattr(namespace, self.dest, ...) Now, all that said, the easiest way of creating a callable that returns an callable where both have the right signatures and the right attributes is to subclass argparse.Action. In fact, doing it any other way is probably crazy. I'm against changing the name of __call__ to invoke because it removes the possibility of defining an action as a function returning another function (which is currently possible), but I'm all for making the documentation strongly recommend subclassing argparse.Action. I would just say something like: You may also specify an arbitrary action by passing a subclass of :class:`argparse.Action`, or another callable object that implements the same interface. I wouldn't bother to go into more detail about implements the same interface - all sane people will just subclass Action. ;-) As to argparse.Action.__init__, hopefully the above bullet points make it clear that you must accept dest and option_strings, but what other keyword arguments you want to accept are up to you. Be sure to call the superclass __init__ to set any attributes that you didn't accept to appropriate default values. A simple example of accepting an additional keyword argument is the _VersionAction, which accepts a version keyword argument that the other actions don't accept. The current example of a custom action should probably define __init__ to show how this works. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13540 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue12776] argparse: type conversion function should be called only once
Steven Bethard steven.beth...@gmail.com added the comment: Could you add a test to verify that custom actions are still getting the converted values passed to their __call__? I suspect this may not be happening under the current patch - if that's the case, you may also need to add conversions in _get_values, where the lines look like value = action.default. Also, action.default == getattr(namespace, action.dest) should probably use is instead of ==. Other than that, the patch looks okay. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12776 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1559549] ImportError needs attributes for module and file name
Nick Coghlan ncogh...@gmail.com added the comment: The keyword-only idea is a backwards compatibility hack we discussed at the PyCon US sprints because ImportError currently accepts an arbitrary number of arguments: raise ImportError(1, 2, 3) Traceback (most recent call last): File stdin, line 1, in module ImportError: (1, 2, 3) We don't really want to be claiming that the module name is some strange value due to existing code that passes multiple arguments, hence the suggestion to make this a keyword-only argument. Regarding import.c, I think Brian misinterpreted Brett's last message. import.c absolutely *should* be modified by this patch, since it's still the default import implementation for the moment. Brett's comment was just to say that *he* wasn't going to do that part, since his aim with the importlib bootstrapping exercise is to nuke most of import.c from orbit :) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1559549 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Can __name__ and __qualname__ be looked up through the method cache? __name__ and __qualname__ are not looked up through the method cache, but their descriptors could be. Changing the descriptors would be caught elsewhere, so there is no need to to add any PyType_Modified to type_set_name and type_set_qualname. However, calls to PyType_Modified will never cause any errors, and if only used for genuine type modifications, will cause no discernible performance degradation. Since PyType_Modified is generally called whenever a type is modified, it is likely to act as a guardian for any future optimisations that require classes to be unchanged.

Various comments of the PEP 393 and your patch.
For compatibility with existing APIs, several representations
may exist in parallel; over time, this compatibility should be phased
out.
and
For compatibility, redundant representations may be computed.
I never understood this statement: in most cases, PyUnicode_READY() replaces
the Py_UNICODE* (wchar_t*) representation by a compact representation.
PyUnicode_AsUnicode(), PyUnicode_AS_UNICODE(), PyUnicode_GET_SIZE(), ... do
reallocate a Py_UNICODE* string for a ready string, but I don't think that it
is a usual use case.
PyUnicode_AS_UNICODE() friends are usually only used to build strings. So
this issue should be documented in a section different than the Abstract, maybe
in a Limitations section.
So even if a third party module uses the legagy Unicode API, the PEP 393 will
still optimize the memory usage thanks to implicit calls to PyUnicode_READY()
(done everywhere in Python source code).
In the current code, the most common case where a string has two
representations is the conversion to wchar_t* on Windows. PyUnicode_AsUnicode()
is used to encode arguments for the Windows Unicode API, and
PyUnicode_AsUnicode() keeps the result in the wstr attribute.
Note: there is also the utf8 attribute which may contain a third representation
if PyUnicode_AsUTF8() or PyUnicode_AsUTF8AndSize() (or the old
_PyUnicode_AsString()) is called.
Objects for which the maximum character is not given at creation time are
called legacy objects, created through PyUnicode_FromStringAndSize(NULL,
length).
They can also be created by PyUnicode_FromUnicode().
Resizing a Unicode string remains possible until it is finalized, generally by
calling PyUnicode_READY.
I changed PyUnicode_Resize(): it is now *always* possible to resize a string.
The change was required because some decoders overallocate the string, and then
resize after decoding the input.
The sentence can be simply removed.
++ 000 = str is not initialized (data are in wstr)
++ 001 = 1 byte (Latin-1)
++ 010 = 2 byte (UCS-2)
++ 100 = 4 byte (UCS-4)
++ Other values are reserved at this time.
I don't like binary numbers, I would prefer decimal numbers here. Binary was
maybe useful when we used bit masks, but we are now using the C unsigned int
field:bit_size; trick for a nicer API. With the new values, it is even easier
to remember them:
1 byte = kind=1
2 bytes = kind=2
4 bytes = kind=4
[PyUnicode_AsUTF8] is thus identical to the existing _PyUnicode_AsString,
which is removed
_PyUnicode_AsString() does still exist and is still heavily used (66 calls). It
is not documented as deprecated in What's New in Python 3.3 (but it is a
private function, so nobody uses it, right?.
This section summarizes the API additions.
PyUnicode_IS_ASCII() is missing.
PyUnicode_CHARACTER_SIZE() has been removed (use kind directly).
UCS4 utility functions:
Py_UCS4_{strlen, strcpy, strcat, strncpy, strcmp, strncpy, strcmp, strncmp,
strchr, strrchr} have been removed.
The following functions are added to the stable ABI (PEP 384), as they
are independent of the actual representation of Unicode objects: ...
... PyUnicode_WriteChar
PyUnicode_WriteChar() allows to modify an immutable object, which is something
specific to CPython. Well, the function does now raise an error if the string
is no more modifiable (e.g. more than 1 reference to the string, the hash has
already been computed, etc.), but I don't know if it should be added to the
stable ABI.
PyUnicode_AsUnicodeAndSize
This function was added to Python 3.3 and is directly deprecated. Why adding a
function to deprecate it? PyUnicode_AsUnicode() and PyUnicode_GET_SIZE() were
not enough?
Deprecations, Removals, and Incompatibilities
Missing: PyUnicode_AS_DATA(), Py_UNICODE_strncpy, Py_UNICODE_strncmp
--
A very important point is not well explained: it is very important that a
(final) string is in its canonical representation. It means that a UCS2
string must contain at least a character bigger than U+00FF for example. Not
only some optimizations rely on the canonical representation, but also some
core methods of the Unicode type.
I tried to list all properties of Unicode objects in the definition of the
PyASCIIbject structure. And I implemented checks in
_PyUnicode_CheckConsistency(). This method is only available in debug mode.

[issue13601] sys.stderr should be unbuffered (or always line-buffered)
Antoine Pitrou pit...@free.fr added the comment:
Line-buffering should be good enough since in practice errors messages
are always terminated by a newline.
What I think too.
I'm hesitant to make it line-buffered by default when directed to a
file, since this could significantly slow down a program that for some
reason produces super-voluminous output (e.g. when running a program
with heavy debug logging turned on).
The slow-down is impressive in relative terms (6x) but the timings are
still small in absolute value:
$ ./python -m timeit -s f=open('/dev/null', 'a', buffering=4096)
f.write('log message\n')
1000 loops, best of 3: 0.156 usec per loop
$ ./python -m timeit -s f=open('/dev/null', 'a', buffering=1) f.write('log
message\n')
100 loops, best of 3: 0.961 usec per loop

We already have -u to switch all stdio to unbuffered. This issue proposes to make stderr line-buffered/unbuffered by default, since it's less surprising than fully buffered.

[issue13592] repr(regex) doesn't include actual regex
Ezio Melotti ezio.melo...@gmail.com added the comment:
If an eval-able re.Regex is used, the flags can be showed as second arg, like:
re.Regex('a', re.I|re.S)
instead of being added to the pattern as in
re.Regex('(?is)a')
The repr can be generated with something like
're.Regex({r.pattern!r}, {r.flags})'.format(r=r)
that currently prints
re.Regex('abc', 50)
but if #11957 is fixed, the result will look like
re.Regex('abc', re.I|re.S)
for a regex created with
r = re.compile('abc', re.I|re.S)

Define usual. There were certainly plenty of occurrences of that in the Python code base, and I believe that extension modules also use it, provided they care about the content of string objects at all. PyUnicode_AS_UNICODE() friends are usually only used to build strings. No. They are also used to inspect them. So even if a third party module uses the legagy Unicode API, the PEP 393 will still optimize the memory usage thanks to implicit calls to PyUnicode_READY() (done everywhere in Python source code). ... unless they inspect a given Unicode string, in which case it will use twice the memory (or 1.5x). Resizing a Unicode string remains possible until it is finalized, generally by calling PyUnicode_READY. I changed PyUnicode_Resize(): it is now *always* possible to resize a string. The change was required because some decoders overallocate the string, and then resize after decoding the input. The sentence can be simply removed. Well, I meant the resizing of strings that doesn't move the object in memory (i.e. unicode_resize). You (apparently) changed its signature to take PyUnicode_Object** (instead of PyUnicode_Object*). It's probably irrelevant since that's a unicodeobject.c-internal function, anyway. PyUnicode_AsUnicodeAndSize This function was added to Python 3.3 and is directly deprecated. Why adding a function to deprecate it? PyUnicode_AsUnicode() and PyUnicode_GET_SIZE() were not enough? If it was not in 3.2, we should certainly remove it right away. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13604 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue13604] update PEP 393 (match implementation)
Martin v. Löwis mar...@v.loewis.de added the comment: (1) Upon string creation, do we want to *promise* to discard the UTF-8 and wstr, so that the caller can memory manage? I don't understand the question. Assuming discards means releases here, then there is no API which releases memory during creation of the string object - let alone that there is any promise to do so. I'm also not aware of any candidate buffer that you might want to release. (2) PyUnicode_AS_DATA(), Py_UNICODE_strncpy, Py_UNICODE_strncmp seemed to be there in the code I was looking at. That's very well possible. What's the question? (3) I can't justify the born-deprecated function PyUnicode_AsUnicodeAndSize. Perhaps rename it with a leading underscore? Though I'm not sure it is really needed at all. Nobody noticed that it is born-deprecated. If it really is, it should be removed before the release. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13604 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13607] Move generator specific sections out of ceval.
New submission from Ron Adam ron3...@gmail.com: The following changes cleanup the eval loop and result in a pretty solid 2 to 3% improvement in pybench for me. And it is about 5% faster for long generators. * Change why enum type to int and #defines. And moved the why defines to opcode.h so that they can be seen by the genrator objects after a yield, return, or exception. * Added an int f_why to frames so the generator can see why it returned from a send. * Refactored generator obj so it can use the f-f_why to determine what to do without having to do several checks first. * Moved the generator specific execption save/swap/and clear out of the cevel main loop. No need to check for those on every function call. The only test that fails is the frame size is test_sys. I left that in for now so someone could check that, and tell me if it's ok to fix it, or if I need to do something else. I also considered putting the why on the tstate object. It might save some memory as there wouldn't be as many of those. -- components: Interpreter Core files: f_why.diff keywords: patch messages: 149583 nosy: ron_adam priority: normal severity: normal status: open title: Move generator specific sections out of ceval. type: performance versions: Python 3.3 Added file: http://bugs.python.org/file23969/f_why.diff ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13607 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue13604] update PEP 393 (match implementation)
Jim Jewett jimjjew...@gmail.com added the comment: So even if a third party module uses the legagy Unicode API, the PEP 393 will still optimize the memory usage thanks to implicit calls to PyUnicode_READY() (done everywhere in Python source code). ... unless they inspect a given Unicode string, in which case it will use twice the memory (or 1.5x). Why is the utf-8 representation not cached when it is generated for ParseTuple et alia? It seems like these parameters are likely to either be re-used as parameters (in which case caching makes sense) or not re-used at all (in which case, the whole string can go away). Well, I meant the resizing of strings that doesn't move the object in memory (i.e. unicode_resize). This may easily fail because the new size can't be found at that location; wouldn't it be better to just encourage proper sizing in the first place? (1) Upon string creation, do we want to *promise* to discard the UTF-8 and wstr, so that the caller can memory manage? I don't understand the question. Assuming discards means releases here, then there is no API which releases memory during creation of the string object - let alone that there is any promise to do so. I'm also not aware of any candidate buffer that you might want to release. When a string is created from a wchar_t array, who is responsible for releasing the original wchar_t array? As I read it now, Python doesn't release the buffer, and the caller can't because maybe Python just pointed to it as memory shared with the canonical representation. (2) PyUnicode_AS_DATA(), Py_UNICODE_strncpy, Py_UNICODE_strncmp seemed to be there in the code I was looking at. That's very well possible. What's the question? Victor listed them as missing. I now suspect he meant missing from the PEP list of deprecated functions and macros, and I just misunderstood. -- Added file: http://bugs.python.org/file23970/pep-0393.txt ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13604 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13609] Add os.get_terminal_size() function
New submission from Denilson Figueiredo de Sá denilso...@gmail.com: Please add a function called os.get_terminal_size() that should return a tuple (width, height). The built-in argparse module would directly benefit from this function, as it would wrap the help text correctly. I'm pretty sure many users would also benefit from it. Once this function gets implemented, issue #13041 can be trivially fixed. There are some suggestions about how to implement this feature in issue #8408. [extra feature:] After this function gets implemented, it might be a good idea to implement some kind of API to detect size changes without requiring probing. (or, at least, the documentation should give some directions about how to achieve it) -- components: Library (Lib) messages: 149586 nosy: denilsonsa priority: normal severity: normal status: open title: Add os.get_terminal_size() function type: enhancement ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13609 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
