The length check for AF_ALG salg_name and salg_type had a off-by-one
error. The code assumed that both values are not necessarily NULL
terminated. However the Kernel code for alg_bind() ensures that the last
byte of both strings are NULL terminated.

Fix xml.dom.minidom cloneNode() on a document with an entity: pass
the correct arguments to the user data handler of an entity (fix an
old copy/paste mistake).
Bug spotted and fix proposed by Charalampos Stratakis, initial
reproducer written by Petr Viktorin.

* tests: Further validate `wraps` functionality in `unittest.mock.Mock`
Add more tests to validate how `wraps` interacts with other features of
mocks.
* Don't call the wrapped object if `side_effect` is set
When a object is wrapped using `Mock(wraps=...)`, if an user sets a
`side_effect` in one of their methods, return the value of `side_effect`
and don't call the original object.
* Refactor what to be called on `mock_call`
When a `Mock` is called, it should return looking up in the following
order: `side_effect`, `return_value`, `wraps`. If any of the first two
return `mock.DEFAULT`, lookup in the next option.
It makes no sense to check for `wraps` returning default, as it is
supposed to be the original implementation and there is nothing to
fallback to.
Replace os.popen() with subprocess.check_output() in the platform module:
* platform.uname() (its _syscmd_ver() helper function) now redirects
stderr to DEVNULL.
* Remove platform.DEV_NULL.
* _syscmd_uname() and _syscmd_file() no longer catch AttributeError.
The "except AttributeError:" was only needed in Python 2, when
os.popen() was not always available. In Python 3,
subprocess.check_output() is always available.
select() calls are retried on EINTR (per PEP 475). However, if a
timeout was provided and the deadline has passed after running the
signal handlers, rlist, wlist and xlist should be cleared since select(2)
left them unmodified.
* posixpath.expanduser() now returns the input path unchanged if
the HOME environment variable is not set and pwd.getpwuid() raises
KeyError (the current user identifier doesn't exist in the password
database).
* Add test_no_home_directory() to test_site.
platform.libc_ver() now uses os.confstr('CS_GNU_LIBC_VERSION') if
available and the *executable* parameter is not set. The default
value of the libc_ver() *executable* parameter becomes None.
Quick benchmark on Fedora 29:
python3 -m perf command ./python -S -c 'import platform; platform.libc_ver()'
94.9 ms +- 4.3 ms -> 33.2 ms +- 1.4 ms: 2.86x faster (-65%)
When using link time optimizations, the -flto flag is passed to
BASECFLAGS, which makes it propagate to distutils. Those flags
should be reserved for the interpreter and the stdlib extension
modules only, thus moving those flags to CFLAGS_NODIST.
Modify asyncio tests to utilize the certificates from the test directory
instead of its own set, as they are the same and with each update they had
to be updated as well.
Fix an undefined behaviour in the pthread implementation of
PyThread_start_new_thread(): add a function wrapper to always return
NULL.
Add pythread_callback struct and pythread_wrapper() to thread_pthread.h.
Remove platform.popen() function, it was deprecated since Python 3.3:
use os.popen() instead.
Rename also the "Removed" section to "API and Feature Removals"
of What's New in Python 3.8.
Fix memory leak in PyUnicode_EncodeLocale() and
PyUnicode_EncodeFSDefault() on error handling.
Changes:
* Fix unicode_encode_locale() error handling
* Fix test_codecs.LocaleCodecTest
Fix mktime() overflow error in test_email: run
test_localtime_daylight_true_dst_true() and
test_localtime_daylight_false_dst_true() with a specific timezone.
The lineno and col_offset attributes of AST nodes for list comprehensions,
generator expressions and tuples are now point to the opening parenthesis or
square brace. For tuples without parenthesis they point to the position
of the first item.
Regression introduced in e3ce695 and 25b804a, where the old parameter
update_tryorder to _synthesize was first ignored, then given the opposite
value in the attempt to fix bpo-31014.
Fix str.format(), float.__format__() and complex.__format__() methods
for non-ASCII decimal point when using the "n" formatter.
Changes:
* Rewrite _PyUnicode_InsertThousandsGrouping(): it now requires
a _PyUnicodeWriter object for the buffer and a Python str object
for digits.
* Rename FILL() macro to unicode_fill(), convert it to static inline function,
add "assert(0 <= start);" and rework its code.
There are some same consts in a module. This commit merges them into
single instance. It reduces number of objects in memory after loading modules.

Importing ProcessPoolExecutor may hang or cause an error when the import
accesses urandom on a low resource platform
https://bugs.python.org/issue29877
The "-I" command line option (run Python in isolated mode) is now
also copied by the multiprocessing and distutils modules when
spawning child processes. Previously, only -E and -s options (enabled
by -I) were copied.
subprocess._args_from_interpreter_flags() now copies the -I flag.
Include/*.h should be the "portable Python API", whereas
Include/cpython/*.h should be the "CPython API": CPython
implementation details.
Changes:
* Create Include/cpython/ subdirectory
* "make install" now creates $prefix/include/cpython and copy
Include/cpython/* to $prefix/include/cpython
* Create Include/cpython/objimpl.h: move objimpl.h code
surrounded by "#ifndef Py_LIMITED_API" to cpython/objimpl.h.
* objimpl.h now includes cpython/objimpl.h
* Windows installer (MSI) now also install Include/ subdirectories:
Include/cpython/ and Include/internal/.
