open(), io.open(), codecs.open() and fileinput.FileInput no longer
accept "U" ("universal newline") in the file mode. This flag was
deprecated since Python 3.3.
This adds a "readlink" method to pathlib.Path objects that calls through
to os.readlink.

Fix stdatomic.h header check for ICC compiler: the ICC implementation
lacks atomic_uintptr_t type which is needed by Python.
Test:
* atomic_int and atomic_uintptr_t types
* atomic_load_explicit() and atomic_store_explicit()
* memory_order_relaxed and memory_order_seq_cst constants
But don't test ATOMIC_VAR_INIT(): it's not used in Python.
test.regrtest now uses process groups in the multiprocessing mode
(-jN command line option) if process groups are available: if
os.setsid() and os.killpg() functions are available.
* bpo-27657: Fix urlparse() with numeric paths
Revert parsing decision from bpo-754016 in favor of the documented
consensus in bpo-16932 of how to treat strings without a // to
designate the netloc.
* bpo-22891: Remove urlsplit() optimization for 'http' prefixed inputs.
Also updates the documentation to clarify the situation surrounding
the digestmod parameter that is required despite its position in the
argument list as of 3.8.0 as well as removing old python2 era
references to "binary strings".
We indavertently had this raise ValueError in 3.8.0 for the missing
arg. This is not considered an API change as no reasonable code would
be catching this missing argument error in order to handle it.
main() is now responsible to send the ANSWER, rather than
ServerProto. main() now waits until it got the HELLO before sending
the ANSWER over the new transport.
Previously, there was a race condition between main() replacing the
protocol and the protocol sending the ANSWER once it gets the HELLO.
TLSv1.3 was disabled for the test: reenable it.
Add a total_nframe field to the traces collected by the tracemalloc module.
This field indicates the original number of frames before it was truncated.
Fix test_compile_dir_maxlevels() on Windows without long path
support: only create 3 subdirectories instead of between 20 and 100
subdirectories.
Fix also compile_dir() to use the current sys.getrecursionlimit()
value as the default maxlevels value, rather than using
sys.getrecursionlimit() value read at startup.
The symbol table handing of PEP572's assignment expressions is not resolving correctly the scope of some variables in presence of global/nonlocal keywords in conjunction with comprehensions.
Currently if any finalizer invoked during garbage collection resurrects any object, the gc gives up and aborts the collection. Although finalizers are assured to only run once per object, this behaviour of the gc can lead to an ever-increasing memory situation if new resurrecting objects are allocated in every new gc collection.
To avoid this, recompute what objects among the unreachable set need to be resurrected and what objects can be safely collected. In this way, resurrecting objects will not block the collection of other objects in the unreachable set.
Add missing stat.S_IFDOOR, stat.S_IFPORT, stat.S_IFWHT,
stat.S_ISDOOR, stat.S_ISPORT, and stat.S_ISWHT values to
the Python implementation of the stat module.
