serge-sans-paille 7105319ada bpo-38634: Allow non-apple build to cope with libedit (GH-16986)
The readline module now detects if Python is linked to libedit at runtime
on all platforms.  Previously, the check was only done on macOS.

If Python is used as a library by a binary linking to libedit, the linker
resolves the rl_initialize symbol required by the readline module against
libedit instead of libreadline, which leads to a segfault.

Take advantage of the existing supporting code to have readline module being
compatible with both situations.

bpo-38631: Avoid Py_FatalError() in readline (GH-16998)
readline now calls PyErr_NoMemory() rather than Py_FatalError() on
memory allocation failure, when importing the module.

bpo-37194: Add a new public PyObject_CallNoArgs() function (GH-13890)
Add a new public PyObject_CallNoArgs() function to the C API: call a
callable Python object without any arguments.

It is the most efficient way to call a callback without any argument.
On x86-64, for example, PyObject_CallFunctionObjArgs(func, NULL)
allocates 960 bytes on the stack per call, whereas
PyObject_CallNoArgs(func) only allocates 624 bytes per call.

It is excluded from stable ABI 3.8.

Replace private _PyObject_CallNoArg() with public
PyObject_CallNoArgs() in C extensions: _asyncio, _datetime,
_elementtree, _pickle, _tkinter and readline.

Zackery Spytz 99d56b5356 bpo-35441: Remove dead and buggy code related to PyList_SetItem(). (GH-11033)
In _localemodule.c and selectmodule.c, remove dead code that would
cause double decrefs if run.

In addition, replace PyList_SetItem() with PyList_SET_ITEM() in cases
where a new list is populated and there is no possibility of an error.

In addition, check if the list changed size in the loop in array_array_fromlist().

Fix compiler warning in call_readline() (GH-10820)
Replace strncpy() with memcpy() in call_readline() to fix the
following warning, the NUL byte is written manually just after:

Modules/readline.c: In function ‘call_readline’:
Modules/readline.c:1303:9: warning: ‘strncpy’ output truncated before
terminating nul copying as many bytes from a string as its length
[-Wstringop-truncation]
         strncpy(p, q, n);

Zvezdan Petkovic c2f082e9d1 bpo-13631: Fix the order of initialization for readline libedit on macOS. (GH-6915)
The editline emulation needs to be initialized *after* the name is
defined. This fixes the long open issue.

bpo-29240: Fix locale encodings in UTF-8 Mode (#5170)
Modify locale.localeconv(), time.tzname, os.strerror() and other
functions to ignore the UTF-8 Mode: always use the current locale
encoding.

Changes:

* Add _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx(). On decoding or
  encoding error, they return the position of the error and an error
  message which are used to raise Unicode errors in
  PyUnicode_DecodeLocale() and PyUnicode_EncodeLocale().
* Replace _Py_DecodeCurrentLocale() with _Py_DecodeLocaleEx().
* PyUnicode_DecodeLocale() now uses _Py_DecodeLocaleEx() for all
  cases, especially for the strict error handler.
* Add _Py_DecodeUTF8Ex(): return more information on decoding error
  and supports the strict error handler.
* Rename _Py_EncodeUTF8_surrogateescape() to _Py_EncodeUTF8Ex().
* Replace _Py_EncodeCurrentLocale() with _Py_EncodeLocaleEx().
* Ignore the UTF-8 mode to encode/decode localeconv(), strerror()
  and time zone name.
* Remove PyUnicode_DecodeLocale(), PyUnicode_DecodeLocaleAndSize()
  and PyUnicode_EncodeLocale() now ignore the UTF-8 mode: always use
  the "current" locale.
* Remove _PyUnicode_DecodeCurrentLocale(),
  _PyUnicode_DecodeCurrentLocaleAndSize() and
  _PyUnicode_EncodeCurrentLocale().

bpo-29240: Ignore UTF-8 Mode in time module (#5148)

bpo-29240: readline now ignores the UTF-8 Mode (#5145)
Add new fuctions ignoring the UTF-8 mode:

* _Py_DecodeCurrentLocale()
* _Py_EncodeCurrentLocale()
* _PyUnicode_DecodeCurrentLocaleAndSize()
* _PyUnicode_EncodeCurrentLocale()

Modify the readline module to use these functions.

Re-enable test_readline.test_nonascii().

Fix CID-1414686: PyInit_readline() handles errors (#4647)
Handle PyModule_AddIntConstant() and PyModule_AddStringConstant()
failures. Add also constants before calling setup_readline(), since
setup_readline() registers callbacks which uses a reference to the
module, whereas the module is destroyed if adding constants fails.

Fix Coverity warning:

CID 1414686: Unchecked return value (CHECKED_RETURN)
2. check_return: Calling PyModule_AddStringConstant without checking
return value (as is done elsewhere 45 out of 55 times).

Nir Soffer fae8f4a9cb bpo-29854: Fix segfault in call_readline() (GH-728)
If history-length is set in .inputrc, and the history file is double the
history size (or more), history_get(N) returns NULL, and python
segfaults. Fix that by checking for NULL return value.

It seems that the root cause is incorrect handling of bigger history in
readline, but Python should not segfault even if readline returns
unexpected value.

This issue affects only GNU readline. When using libedit emulation
system history size option does not work.

Replace
    PyObject_CallFunction(func, "O", arg)
and
    PyObject_CallFunction(func, "O", arg, NULL)
with
    _PyObject_CallArg1(func, arg)

Replace
    PyObject_CallFunction(func, NULL)
with
    _PyObject_CallNoArg(func)

_PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate
memory on the C stack.
