* Add _PyCoreConfig_ReadFromArgv() function which parses command line
options: move code from main.c to coreconfig.c.
* Add _PyCoreConfig_Write() to write the new configuration: coerce
the LC_CTYPE locale, set Py_xxx global configuration variables,
etc.
* _PyCoreConfig_ReadFromArgv() now only changes the LC_CTYPE locale
temporarily. _PyCoreConfig_Write() becomes responsible to set the
LC_CTYPE locale.
* Add _Py_SetArgcArgv() and _Py_ClearArgcArgv() functions
* Rename many "pymain_xxx()" functions
* Add "const" to some function parameters
* Reorganize main.c to declare functions in the order in which they
are called.
* Add PyBuildExt.srcdir atribute in setup.py: the source directory is
now always absolute.
* Add PyBuildExt.inc_dirs and PyBuildExt.lib_dirs attributes:
replace 'inc_dirs' and 'lib_dirs' local variables of
detect_modules().
* Replace "from distutils.errors import *"
with "from distutils.errors import CCompilerError, DistutilsError"
to be able to use static analyzers like pyflakes
* Reorder imports.
* Add PyBuildExt.add() which adds the extension directly to
self.extensions, rather than using a temporary 'exts' local
variable in detect_modules() and then add 'exts' to self.extensions
* Convert 'missing' local variable from detect_modules()
into PyBuildExt.missing attribute
* _detect_openssl(), _decimal_ext() and _detect_nis() now call
directly self.add(), rather than returning an extension
(or None if not found).
* Rename _decimal_ext() to _detect_decimal() for consistency with
other methods.
* Move fields from _PyMain to _PyCoreConfig:
* skip_first_line
* run_command
* run_module
* run_filename
* Replace _PyMain.stdin_is_interactive with a new
stdin_is_interactive(config) function
* Rename _PyMain to _PyArgv. Add "const _PyArgv *args" field
to _PyCmdline.
Add a new _Py_INIT_EXIT() macro to be able to exit Python with an
exitcode using _PyInitError API. Rewrite function calls by
pymain_main() to use _PyInitError.
Changes:
* Remove _PyMain.err and _PyMain.status field
* Add _Py_INIT_EXIT() macro and _PyInitError.exitcode field.
* Rename _Py_FatalInitError() to _Py_ExitInitError().
The whole coreconfig.h header is now excluded from Py_LIMITED_API.
Move functions definitions into a new internal pycore_coreconfig.h
header.
* Move Include/coreconfig.h to Include/cpython/coreconfig.h
* coreconfig.h header is now excluded from Py_LIMITED_API
* Move functions to pycore_coreconfig.h
Use locale.getpreferredencoding() rather than locale.getlocale() to
get the locale encoding. With some locales, locale.getlocale()
returns the wrong encoding.
For example, on Fedora 29, locale.getlocale() returns ISO-8859-1
encoding for the "en_IN" locale, whereas
locale.getpreferredencoding() reports the correct encoding: UTF-8.
* Rename globals to upper case to better distinguish if a variable is
global or local:
* Rename cross_compiling to CROSS_COMPILING
* Rename host_platform to HOST_PLATFORM
* Rename disabled_module_list to DISABLED_MODULE_LIST
* Add MS_WINDOWS, CYGWIN and MACOS constants.
* Use booleans: replace "return 0" with "return False"
and replace "return 1" with "return True"
The standard math library (libm) may follow IEEE-754 recommendation to
include an implementation of sinPi(), i.e. sinPi(x):=sin(pi*x).
And this triggers a name clash, found by FreeBSD developer
Steve Kargl, who worken on putting sinpi into libm used on FreeBSD
(it has to be named "sinpi", not "sinPi", cf. e.g.
https://en.cppreference.com/w/c/experimental/fpext4).
Per POSIX, `nice(3)` requires `unistd.h` and `exit(3)` requires `stdlib.h`.
Fixing the test will prevent false positives with pedantic compilers like clang.
Responding to suggestions on the tracker and some off-line suggestions.
Davin suggested that english named accessors instead of greek letters would result in more intelligible user code. Steven suggested that the parameters still need to be *mu* and *theta* which are used elsewhere (and I noted those parameter names are used in linked-to resources).
Michael suggested proving-out the API by seeing whether it generalized to *Lognormal*. I did so and found that Lognormal distribution parameters *mu* and *sigma* do not represent the mean and standard deviation of the lognormal distribution (instead, they are for the underlying regular normal distribution).
Putting these ideas together, we have NormalDist parameterized by *mu* and *sigma* but offering English named properties for accessors. That gives lets us match other API that access mu and sigma, it matches the external resources on the topic, gives us clear english names in user code. The API extends nicely to LogNormal where the parameters and the summary statistic accessors are not the same.
