Consolidates the logic for nlargest() into a single function so that
decoration tuples (elem,order) or (key, order, elem) only need to
be formed when a new element is added to the heap. Formerly, a tuple
was created for every element regardless of whether it was added to
the heap.
The change reduces the number of tuples created, the number of ordering
integers created, and total number of tuple comparisons.
The paragraph above already says, clearly and correctly, that
"However, being completely deterministic, it is not suitable for
all purposes, and is completely unsuitable for cryptographic purposes."
Also we should make any promises about SystemRandom or os.urandom()
being cryptographically secure (they may be, but be can't validate
that promise). Further, those are actual random number generators
not psuedo-random number generators.
The new parser does not rely on Spark (which is now removed from our repo),
uses modern 3.x idioms and is significantly smaller and simpler.
It generates exactly the same AST files (.h and .c), so in practice no builds
should be affected.
instead relying on OpenSSL source being configured and ready to build. The
``PCbuild\build_ssl.py`` script has been re-written and re-named to
``PCbuild\prepare_ssl.py``, and takes care of configuring OpenSSL source
for both 32 and 64 bit platforms. OpenSSL sources obtained from
svn.python.org will always be pre-configured and ready to build.
Issue #21435: Segfault in gc with cyclic trash
Changed the iteration logic in finalize_garbage() to tolerate objects vanishing
from the list as a side effect of executing a finalizer.
in order to have the same resolution as pthreads condition variables.
At the same time, it must be large enough to accept 31 bits of
milliseconds, which is the maximum timeout value in the windows API.
A PY_LONG_LONG of microseconds fullfills both requirements.
This closes issue #20737
