bpo-43172: readline now passes its tests when built against libedit.
Existing irreconcilable API differences remain in readline.get_begidx
and readline.get_endidx behavior based on libreadline vs libedit use.
A note about that has been documented.
In contrast to macOS, libedit is available as its own include file and
library on Linux systems to prevent file name clashes. So if both
libraries are available on the system, readline is currently chosen by
default; and if only libedit is available, it is not found at all. This
patch adds a way to link against libedit by adding the following
arguments to configure:
--with-readline link against libreadline (the default)
--with-readline=editline link against libeditline
--with-readline=no disable building the readline module
--without-readline (same)
The runtime detection of libedit vs. readline was already done in commit
7105319ada (2019-12-04, serge-sans-paille: "bpo-38634: Allow
non-apple build to cope with libedit (GH-16986)").
Fixes: GH-12076 ("bpo-13501 Build or disable readline with Editline")
Fixes: bpo-13501 ("Make libedit support more generic; port readline / libedit to FreeBSD")

PyObject_RichCompareBool() returns -1 on error, but this case is
not handled by the find_in_strong_cache() function. Any exception
raised by PyObject_RichCompareBool() should be propagated.
* bpo-42979: Enhance abstract.c assertions checking slot result
Add _Py_CheckSlotResult() function which fails with a fatal error if
a slot function succeeded with an exception set or failed with no
exception set: write the slot name, the type name and the current
exception (if an exception is set).
The Py_FatalError() function and the faulthandler module now dump the
list of extension modules on a fatal error.
Add _Py_DumpExtensionModules() and _PyModule_IsExtension() internal
functions.
Convert the 6 CJK codec extension modules (_codecs_cn, _codecs_hk,
_codecs_iso2022, _codecs_jp, _codecs_kr and _codecs_tw) to the
multiphase initialization API (PEP 489).
Remove getmultibytecodec() local cache: always import
_multibytecodec. It should be uncommon to get a codec. For example,
this function is only called once per CJK codec module.
Fix a reference leak in register_maps() error path.
A compiler that doesn't define `__has_builtin` will error out when it is
used on the same line as the check for it.

The coding cookie (ex: "# coding: latin1") is now ignored in the
command passed to the -c command line option.
Since pymain_run_command() uses UTF-8, pass PyCF_IGNORE_COOKIE
compiler flag to the parser.
pymain_run_python() no longer propages compiler flags between
function calls.
Add pycore_atomic_funcs.h internal header file: similar to
pycore_atomic.h but don't require to declare variables as atomic.
Add _Py_atomic_size_get() and _Py_atomic_size_set() functions.
Port the _thread extension module to the multiphase initialization
API (PEP 489) and convert its static types to heap types.
Add a traverse function to the lock type, so the garbage collector
can break reference cycles.
"uint8_t day" is unsigned and so "day < 0" test is always true.
Remove the test to fix the following warnings on Windows:
modules\_zoneinfo.c(1224): warning C4068: unknown pragma
modules\_zoneinfo.c(1225): warning C4068: unknown pragma
modules\_zoneinfo.c(1227): warning C4068: unknown pragma
* Fix ExceptHookArgsType name: "_thread.ExceptHookArgs", instead of
"_thread._ExceptHookArgs".
* PyInit__thread() no longer intializes interp->num_threads to 0:
it is already done in PyInterpreterState_New().
* Use PyModule_AddType(), Py_NewRef() and Py_XNewRef().
* Replace str_dict variable with _Py_IDENTIFIER(__dict__).
* Remove assert(Py_IS_TYPE(obj, &Locktype)) from release_sentinel()
to avoid having to retrive the type from this callback.
* Add thread_bootstate_free()
* Rename t_bootstrap() to thread_run()
* bootstate structure: rename keyw member to kwargs
atexit._run_exitfuncs() now logs callback exceptions using
sys.unraisablehook, rather than logging them directly into
sys.stderr and raising the last exception.
Run GeneralTest of test_atexit in a subprocess since it calls
atexit._clear() which clears all atexit callbacks.
_PyAtExit_Fini() sets state->callbacks to NULL.
If config->run_filename doesn't exist, log the error into sys.stderr
using "%R" format, to escape properly unencodable characters (usually
with backslashreplace).
* Add _PyAtExit_Call() function and remove pyexitfunc and
pyexitmodule members of PyInterpreterState. The function
logs atexit callback errors using _PyErr_WriteUnraisableMsg().
* Add _PyAtExit_Init() and _PyAtExit_Fini() functions.
* Remove traverse, clear and free functions of the atexit module.

At Python exit, if a callback registered with atexit.register()
fails, its exception is now logged. Previously, only some exceptions
were logged, and the last exception was always silently ignored.
Add _PyAtExit_Call() function and remove
PyInterpreterState.atexit_func member. call_py_exitfuncs() now calls
directly _PyAtExit_Call().
The atexit module must now always be built as a built-in module.
pymain_run_file() no longer encodes the filename: pass the filename
as an object to the new _PyRun_AnyFileObject() function.
Add new private functions:
* _PyRun_AnyFileObject()
* _PyRun_InteractiveLoopObject()
* _Py_FdIsInteractive()
- Copy existing xxlimited to xxlimited53 (named for the limited API version it uses)
- Build both modules, both in debug and release
- Test both modules
Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector:
- collections.OrderedDict.items
- dict.items
- enumerate
- functools.reduce
- itertools.combinations
- itertools.combinations_with_replacement
- itertools.permutations
- itertools.product
- itertools.zip_longest
- zip
Previously, they could have become untracked by a prior garbage collection.
No longer use deprecated aliases to functions:
* Replace PyObject_MALLOC() with PyObject_Malloc()
* Replace PyObject_REALLOC() with PyObject_Realloc()
* Replace PyObject_FREE() with PyObject_Free()
* Replace PyObject_Del() with PyObject_Free()
* Replace PyObject_DEL() with PyObject_Free()
No longer use deprecated aliases to functions:
* Replace PyMem_MALLOC() with PyMem_Malloc()
* Replace PyMem_REALLOC() with PyMem_Realloc()
* Replace PyMem_FREE() with PyMem_Free()
* Replace PyMem_Del() with PyMem_Free()
* Replace PyMem_DEL() with PyMem_Free()
Modify also the PyMem_DEL() macro to use directly PyMem_Free().
* bpo-40791: Make compare_digest more constant-time.
The existing volatile `left`/`right` pointers guarantee that the reads will all occur, but does not guarantee that they will be _used_. So a compiler can still short-circuit the loop, saving e.g. the overhead of doing the xors and especially the overhead of the data dependency between `result` and the reads. That would change performance depending on where the first unequal byte occurs. This change removes that optimization.
(This is change #1 from https://bugs.python.org/issue40791 .)
