[issue31443] Possibly out of date C extension documentation

[issue26750] Mock autospec does not work with subclasses of property()
Amaury Forgeot d'Arc added the comment: inspect.isdatadescriptor() is better indeed. (I was initially working on an old version of mock.py which does not import inspect, and I did not want to add the dependency there). - inspect uses hasattr(type(obj)) instead of hasatr(obj). This is better, (but does not work for 2.x old-style classes) - my patch tested for __del__... this is completely wrong, it should have been __delete__. oops. inspect.isdatadescriptor() does not test for __delete__. This is insaccurate, but I doubt it will ever matter. This is only possible for Python-defined descriptors, the C implementation always exposes both __set__ and __delete__ when tp_set is filled.

New submission from Amaury Forgeot d'Arc: When an extension module is compiled with CPython3.4, the nb_matrix_multiply slot is not filled, and no memory is allocated for it.

Amaury Forgeot d'Arc added the comment: So, dir(C) contains '__mro__', but not 'mro'? I'm -1 on the change. From https://docs.python.org/3.4/library/functions.html#dir : Note Because dir() is supplied primarily as a convenience for use at an interactive prompt, it tries to supply an interesting set of names more than it tries to supply a rigorously or consistently defined set of names, and its detailed behavior may change across releases. For example, metaclass attributes are not in the result list when the argument is a class. dir(sys) does not list its __str__ method, even if sys.__str__() works, because returning only the explicit content of the module is more interesting to the user. Likewise, the implementation of dir(__class__) returns the methods and attributes of *instances* because [someone decided that] it's the most relevant info for the user. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22790 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20485] Enable 'import Non-ASCII.pyd'
Amaury Forgeot d'Arc added the comment:
I'd use a much simpler encoding.
Maybe something like
name.encode('unicode-escape').replace(b'\\', b'_')
As you said, simplicity is important for tools which generate code!

[issue19088] TypeError with pickle in embedded python3.3 when starting multiple Interpreters.
Amaury Forgeot d'Arc added the comment: The NoneType that fails is in typeobject.c: _PyObject_CallMethodId(copyreg, PyId__slotnames, O, cls); The error here is that copyreg comes from a cached reference to the module, stored in a static variable (cached_copyreg_module). When the interpreter shuts down the first time, all the module members are set to None... but the reference is kept forever. This variable should be reset, and reloaded (with a fresh module from the new interpreter) the next time it's used. I added a call to _PyType_Fini() in Py_EndInterpreter, this fixes the given example. Two sets of questions though: - There are many of these _Fini functions, called in Py_Finalize. Which ones should we call in Py_EndInterpreter? and why? Maybe this PyType_Fini() is not a _Fini, but should be renamed PyType_EndInterpreter? - one copyreg for multiple interpreters... this looks wrong: each interpreter has its own list of modules, but copyreg.__globals__ belongs to only one... A good solution would be to cache the copyreg module in the PyInterpreterState (it already has codec_search_cache). Or use PyImport_GetModuleDict() -- nosy: +amaury.forgeotdarc ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue19088 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Amaury Forgeot d'Arc added the comment: RPython... let's be serious. The code of pythonw.exe is very simple, see PC/WinMain.c. No, pythonw.exe is not meant to suppresses the terminal window on startup. This is only a consequence of being a windows application. There is a lot of documentation about this, for example: http://comsci.liu.edu/~murali/win32gui/Win32Apps.htm - python.exe is a regular console application, with a main() function. - pythonw.exe is a gui application, with a WinMain() function; as a consequence, stdout/stderr won't work properly.

Some workarounds: - don't use pythonw.exe in a console, it's meant to be a *windows* application, without standard streams.

[issue18298] pythonw.exe fails with redirected stderr
Amaury Forgeot d'Arc added the comment:
The proper solution if you use pythonw.exe is to define sys.stdout/sys.stderr
yourself in pythonw.exe::
sys.stdout = open('c:/temp/output.txt', 'w')
IOW, do the redirect from inside the program, don't rely on the shell which (by
design?) does not work correctly with /subsytem:windows binaries.
Again, this is a workaround for 2.7, because no backward-compatible fix could
be found.

For this reason, additional data cannot be stored before the variable-length section, only after. It is possible to store data after the variable section, and CPython does it already for the __dict__ slot of user-defined classes:: bytes.__basicsize__ 33 class B(bytes): pass ... B.__basicsize__ 41 B.__dictoffset__ -8 Note that tp_basicsize was increased by the size of the additional data (here a PyObject*). To access your data, the logic is something like:: tp-tp_basicsize + (obj-ob_size * tp-tp_itemsize) - sizeof(MyData) The function _PyObject_GetDictPtr() has similar code, and already aligns to the pointer size. Of course, at the end of one object you cannot have *both* a __dict__ slot and custom data. The custom type needs to either disallow subclassing, or provide a (negative) tp_dictoffset. Also, some care may be required if the base class uses a custom allocator. Overall, I think it's a bit involved, but doable. I close the issue as works for me, someone can reopen if there is something wrong in the base types. -- nosy: +amaury.forgeotdarc resolution: - works for me status: open - closed ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue515074 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue3329] API for setting the memory allocator used by Python

[issue18178] Redefinition of malloc(3) family of functions at build time
Amaury Forgeot d'Arc added the comment: Said simpler: dlmalloc.c code is indeed compiled twice: - once as part of closures.c, which #include dlmalloc.c; this is done carefully (with 'static' and 'USE_DL_PREFIX') to not clash with standard malloc functions. - once as a separate target; without USE_DL_PREFIX it will define functions named malloc() and free()... The second one is not necessary, of course. The patch looks good to me. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18178 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
