os.listdir(-1) and os.scandir(-1) now fail with OSError(errno.EBADF)
rather than listing the current directory.
os.listxattr(-1) now fails with OSError(errno.EBADF) rather than
listing extended attributes of the current directory.
Optimize memoryview comparison: a memoryview is equal to itself, there is no
need to compare values, except if it uses float format.
Benchmark comparing 1 MiB:
from timeit import timeit
with open("/dev/random", 'br') as fp:
data = fp.read(2**20)
view = memoryview(data)
LOOPS = 1_000
b = timeit('x == x', number=LOOPS, globals={'x': data})
m = timeit('x == x', number=LOOPS, globals={'x': view})
print("bytes %f seconds" % b)
print("mview %f seconds" % m)
print("=> %f time slower" % (m / b))
Result before the change:
bytes 0.000026 seconds
mview 1.445791 seconds
=> 55660.873940 time slower
Result after the change:
bytes 0.000026 seconds
mview 0.000028 seconds
=> 1.104382 time slower
This missed optimization was discovered by Pierre-Yves David
while working on Mercurial.

* introduce executable specific linker flags
Add PY_CORE_EXE_LDFLAGS and EXE_LDFLAGS which stores executable specific
LDFLAGS, replacing PY_CORE_LDFLAGS for building
executable targets.
If PY_CORE_EXE_LDFLAGS / EXE_LDFLAGS is not provided, then it defaults
to the value of PY_CORE_LDFLAGS which is the existing behaviour.
If both flags are supplied, and there is a need
to distinguish between executable and shared specific LDFLAGS,
in particular, PY_CORE_LDFLAGS should contain the shared specific LDFLAGS.
* documentation for new linker flags
* update Misc folder documentation
* Update Makefile.pre.in

The handle parameter was being ignored in the POSIX implementation
of CDLL._load_library(), causing it to always call _dlopen() even
when a valid handle was provided. This was a regression introduced
in recent refactoring.
Since os.stat() raises an OSError for existing named pipe "\\.\pipe\...",
os.path.exists() always returns False for it, and tempfile.mktemp() can
return a name that matches an existing named pipe.
So, tempfile.mktemp() cannot be used to generate unique names for named
pipes. Instead, CreateNamedPipe() should be called in a loop with
different names until it completes successfully.
