* bpo-35588: Implement mod and divmod operations for Fraction type by spelling out the numerator/denominator calculation, instead of instantiating and normalising Fractions along the way. This speeds up '%' and divmod() by 2-3x.
* bpo-35588: Also reimplement Fraction.__floordiv__() using integer operations to make it ~4x faster.
* Improve code formatting.
Co-Authored-By: scoder <stefan_ml@behnel.de>
* bpo-35588: Fix return type of divmod(): the result of the integer division should be an integer.
* bpo-35588: Further specialise __mod__() and inline the original helper function _flat_divmod() since it's no longer reused.
* bpo-35588: Add some tests with large numerators and/or denominators.
* bpo-35588: Use builtin "divmod()" function for implementing __divmod__() in order to simplify the implementation, even though performance results are mixed.
* Rremove accidentally added empty line.
* bpo-35588: Try to provide more informative output on test failures.
* bpo-35588: Improve wording in News entry.

* Remove stray space.
Also skip the same tests when using the undefined behavior sanitizer
as they much with the output.
Updates a regex in another test to use multi-line mode so that the ubsan
buildbot should pass again rather than also adding a skip to that one.
Add Clang Memory Sanitizer build instrumentation to work around
false positives from the socket and time modules as well as skipping
a couple test_faulthandler tests.
* bpo-32492: 2.5x speed up in namedtuple attribute access using C fast path
* Add News entry
* fixup! bpo-32492: 2.5x speed up in namedtuple attribute access using C fast path
* Check for tuple in the __get__ of the new descriptor and don't cache the descriptor itself
* Don't inherit from property. Implement GC methods to handle __doc__
* Add a test for the docstring substitution in descriptors
* Update NEWS entry to reflect time against 3.7 branch
* Simplify implementation with argument clinic, better error messages, only __new__
* Use positional-only parameters for the __new__
* Use PyTuple_GET_SIZE and PyTuple_GET_ITEM to tighter the implementation of tuplegetterdescr_get
* Implement __set__ to make tuplegetter a data descriptor
* Use Py_INCREF now that we inline PyTuple_GetItem
* Apply the valid_index() function, saving one test
* Move Py_None test out of the critical path.
There is a race condition in SelectorEventLoopUnixSockSendfileTests that causes the prepare() method return a non connected server protocol, making the cleanup() method skips the correct handling of the transport. This commit makes prepare() always return a connected server protocol that can always be cleaned up correctly.
There is a race condition regarding signal delivery in test_signal_handling_args for
test_asyncio.test_events.KqueueEventLoopTests. The signal can be received at any moment outside the time window provided in the test. The fix is to wait for the signal to be received instead with a bigger timeout.
Command line options for the xlc compiler behave differently from gcc and clang,
so skip this test case for now when xlc is the compiler.
Patch by aixtools (Michael Felt)
* Fix test_mktime on AIX by adding code to get mktime to behave the
same way as it does on other *nix systems
* Fix test_pthread_getcpuclickid in AIX by adjusting the test case
expectations when running on AIX in 32-bit mode
Patch by Michael Felt.
Depending on system config, a missing candidate compiler name may be
reported as the empty string rather than as None, so adjust the test
helper accordingly.
AIX allows a trailing slash on local file system paths, which isn't what we want
in http.server. Accordingly, check explicitly for this case in the server code,
rather than relying on the OS raising an exception.
Patch by Michael Felt.
This test case needs "signed short" bitfields, but the
IBM XLC compiler (on AIX) does not support this.
Skip the code and test when AIX and XLC are used.
Use __xlc__ as identifier to detect the XLC compiler.
* use platform.system() as runtime test, rather than sys.platform() build-time test
* IPv6 zone id support on AIX is limited to inet_pton6_zone(), so skip related
getaddrinfo() and getnameinfo() tests as not supported
"Include/token.h", "Lib/token.py" (containing now some data moved from
"Lib/tokenize.py") and new files "Parser/token.c" (containing the code
moved from "Parser/tokenizer.c") and "Doc/library/token-list.inc" (included
in "Doc/library/token.rst") are now generated from "Grammar/Tokens" by
"Tools/scripts/generate_token.py". The script overwrites files only if
needed and can be used on the read-only sources tree.
"Lib/symbol.py" is now generated by "Tools/scripts/generate_symbol_py.py"
instead of been executable itself.
Added new make targets "regen-token" and "regen-symbol" which are now
dependencies of "regen-all".
The documentation contains now strings for operators and punctuation tokens.
The Code Context menu label now toggles between Show/Hide Code Context.
The Zoom Height menu now toggles between Zoom/Restore Height.
Zoom Height has moved from the Window menu to the Options menu.
