[issue30002] Minor change to https://docs.python.org/3.6/extending/building.html
by Arthur Goldberg April 6, 2017

April 6, 2017

New submission from Arthur Goldberg: The core example on this page starts: from distutils.core import setup, Extension module1 = Extension('demo', sources = ['demo.c']) ... I suggest that 'sources = ['demo.c']' be changed to 'sources = ['demomodule.c']', because this would make the example consistent with https://docs.python.org/3.6/extending/extending.html which says: "Begin by creating a file spammodule.c. (Historically, if a module is called spam, the C file … [View More]

[issue29997] Suggested changes for https://docs.python.org/3.6/extending/extending.html
by Arthur Goldberg April 5, 2017

April 5, 2017

New submission from Arthur Goldberg: I've just taught myself how to write C extensions to Python with https://docs.python.org/3.6/extending/extending.html. I think it's quite good. Nevertheless, I've some suggested improvements. These all use the vi s/// replacement syntax. Ambiguous 'it': s/If the latter header file does not exist on your system, it declares the functions malloc(), free() and realloc() directly./If the latter header file does not exist on your system, Python.h declares the … [View More]functions malloc(), free() and realloc() directly./ Unclear, as 'The C function' refers to the specific example, whereas 'always has' implies that this applies to all calls from Python to C: s/The C function always has two arguments, conventionally/A C function called by Python always has two arguments, conventionally/ In PyMODINIT_FUNC PyInit_spam(void) { PyObject *m; m = PyModule_Create(&spammodule); if (m == NULL) return NULL; SpamError = PyErr_NewException("spam.error", NULL, NULL); Py_INCREF(SpamError); PyModule_AddObject(m, "error", SpamError); return m; } remove m = PyModule_Create(&spammodule); if (m == NULL) return NULL; and replace it with ... because it won't compile because spammodule has not been described yet on the page. Self-contradictory: 'normally always' is an oxymoron. s/It should normally always be METH_VARARGS or METH_VARARGS | METH_KEYWORDS; a value of 0 means that an obsolete variant of PyArg_ParseTuple() is used./It should always be METH_VARARGS or METH_VARARGS | METH_KEYWORDS; however, legacy code may use 0, which indicates that an obsolete variant of PyArg_ParseTuple() is being used./ Incomplete: this comment doesn't contain a complete thought s/module documentation, may be NULL/pointer to a string containing the module's documentation, or NULL if none is provided/ Provide hyperlink: for user convenience, add a hyperlink to 'Modules/xxmodule.c' s/included in the Python source distribution as Modules/xxmodule.c/included in the Python source distribution as Modules/xxmodule.c/ Incomplete: It would be good to lead programmers towards the easiest approach. s/ If you use dynamic loading,/<new paragraph> If you can use dynamic loading, the the easiest approach is to use Python's distutils module to build your module.

[issue28415] PyUnicode_FromFormat integer format handling different from printf about zeropad
by Terry J. Reedy April 5, 2017

April 5, 2017

Terry J. Reedy added the comment: (Response to what I believe is latest patch.) In msg278666, my two suggestions were 'either...or', not both. The list came from Antti's msg278528, but the correct list for Python appears to be different, and different for bytes and unicode. When I made the suggestion, I did not realize that 'exactly' was repeated for each conversion type in a table. As a note, I think the following might work. "For <list of> conversion types, the 0-conversion flag … [View More]

Dominic Mayers added the comment: I simplified the patch. Using a class as a factory function is the simplest case, so I took advantage of this. I also give one way to pass extra parameters to the handler in the factory function, because it's the main reason why we cannot always use a class. ---------- Added file: http://bugs.python.org/file46774/Issue29947_for_discussion_02.patch _______________________________________ Python tracker <report(a)bugs.python.org> <http://bugs.python.org/issue29947> _______________________________________
