and stored in pyconfig.h as the new HAVE_GETRANDOM_SYSCALL define.

Fix os.urandom() tests using file descriptors if os.urandom() uses getrandom().

retried with the recomputed delay, except if the signal handler raises an
exception (PEP 475).

Modify also test_signal to use a monotonic clock instead of the system clock.

add private method to enum to support replacing global constants with Enum members:
- search for candidate constants via supplied filter
- create new enum class and members
- insert enum class and replace constants with members via supplied module name
- replace __reduce_ex__ with function that returns member name, so previous Python versions can unpickle
modify IntEnum classes to use new method

broken after converting instance attributes to properies in issue #2211.

available, syscall introduced in the Linux kernel 3.17. It is more reliable
and more secure, because it avoids the need of a file descriptor and waits
until the kernel has enough entropy.

Use a Python source file (linecache.__file__) instead of /etc/passwd.

Modify also linecache docstrings to clarify the linecache is written to cache
Python source files, not any text files.

source files, even if "it works" with other text files encoded to UTF-8.

Use None as a sentinel to stop a worker.

PyMarshal_ReadShortFromFile() can fail.

Detect also earlier PyMarshal_Read*() errors in zipimport.

the caller can replace the directory with a different file kind.

The bottom-up way, os.walk(topdown=False), still uses entry.is_symlink(), and
so can be faster than Python 3.4.

Retry open()/fopen() if it fails with EINTR and the Python signal handler
doesn't raise an exception.

Setting attributes key, value and coded_value directly now is deprecated.
update() and setdefault() now transform and check keys.  Comparing for
equality now takes into account attributes key, value and coded_value.
copy() now returns a Morsel, not a dict.  repr() now contains all attributes.
Optimized checking keys and quoting values.  Added new tests.
