* Always return bytes from _HackedGetData.get_data().
Ensure the imp.load_source shim always returns bytes by reopening the file in
binary mode if needed. Hash-based pycs have to receive the source code in bytes.
It's tempting to change imp.get_suffixes() to always return 'rb' as a mode, but
that breaks some stdlib tests and likely 3rdparty code, too.
Most of the change involves fixing up the test suite, which previously made
the assumption that there wouldn't be a new line if the input didn't end in
one.

subprocess.Popen now copies the startupinfo argument to leave it
unchanged: it will modify the copy, so that the same STARTUPINFO
object can be used multiple times.
Add subprocess.STARTUPINFO.copy() method.
Result of function interpreter_requires_environment() depends on os.environ.
This was not covered by the tests, leading to fail when PYTHONHOME was set.
Fix test_forkserver_sigkill() of test_multiprocessing_forkserver:
give more time to the first child process to complete, double the
sleep in the parent process.
Reduce also the child process sleep from 1000 ms to 500 ms, to not change
the total duration of the test.
The Opera Browser was using a outdated command line invocation that resulted in an incorrect URL being opened in the browser when requested using the webbrowser module.
* Correct the arguments passed to the Opera Browser when opening a new URL.
When hunting memory leaks using -R 3:3, test_imap_unordered() of
test_multiprocessing leaks randomly a few memory blocks. It is a
false alarm: when testing using -R 3:20 for example, no leak is
detected.
Modify test_imap_unordered() to be closer to test_imap():
* Only test 10 numbers instead of 1000: it's a pool of 4 processes, so
10 is enough to test at least one number per process
* Use chunksize=100 instead of chunksize=53 to mimick test_imap()
* `flags` is indeed deprecated, but there is a validation on its value for
backwards compatibility reasons. This adds mention of this in the docs.
* The docs say that `sizehint` is deprecated and ignored, but it is still
used when `epoll_create1()` is unavailable. This adds mention of this in
the docs.
* `sizehint=-1` is acceptable again, and is replaced with `FD_SETSIZE-1`.
This is needed to have a default value available at the Python level,
since `FD_SETSIZE` is not exposed to Python. (see: bpo-31938)
* Reject `sizehint=0` since it is invalid to pass on to `epoll_create()`.
The relevant tests have also been updated.
bpo-30339, bpo-33913:
* Increase timeout from 10 seconds to 1 minute in
test_source_main_skipped_in_children source of
test_multiprocessing_main_handling.
* Replace time.time() with time.monotonic().
* On timeout, include the duration in the error message.
test_mymanager_context() now also accepts -SIGTERM as an expected
exitcode for the manager process. The process is killed with SIGTERM
if it takes longer than 1 second to stop.
Tolerate a different of 50 ms, instead of just 30 ms, in
test_timeout() of multiprocessing tests. This change should fix such
test failure on Windows:
FAIL: test_timeout (test.test_multiprocessing_spawn.WithProcessesTestQueue)
Traceback (most recent call last):

Fix bug in `Lib/test/libregrtest/runtest.py` that makes running tests an extra time than the specified number of runs.
Add check for invalid --huntrleaks/-R parameters.
* Add support.MS_WINDOWS: True if Python is running on Microsoft Windows.
* Add support.MACOS: True if Python is running on Apple macOS.
* Replace support.is_android with support.ANDROID
* Replace support.is_jython with support.JYTHON
* Cleanup code to initialize unix_shell
* Fix also PyInit__gdbm() to catch errors.
* test.pythoninfo: add gdbm.version
* test_dbm_gnu now logs GDBM_VERSION when run in verbose mode.
* pythoninfo: rename function to collect_gdbm()
bpo-33671
* use memoryview() with size == file size on Windows, see https://github.com/python/cpython/pull/7160#discussion_r195405230
* release intermediate (sliced) memoryview immediately
* replace "OSX" occurrences with "macOS"
* add some unittests for copyfileobj()
with debuglevel=1 only the header keys got printed. With
this change the header values get printed as well and the single
header entries get '\n' as a separator.
Using gdbm 1.15, creating a database creates a file of 16 MiB. Adding
a small entry and then modifying the small entry doesn't change the
file size. Modify test_dbm_gnu to be less strict: allow that the file
size doesn't change.
* Test exists(), lexists(), isdir(), isfile(), islink(), ismount()
with bytes paths.
* Remove unneeded silencing DeprecationWarning for ismount() with
bytes path.
* Test common functions with unencodable and undecodable paths.
* Minor clean up and refactoring.
