Fix a race condition in Popen of
multiprocessing.popen_spawn_win32. The child process now duplicates
the read end of pipe instead of "stealing" it.
Previously, the read end of pipe was "stolen" by the child process,
but it leaked a handle if the child process had been terminated
before it could steal the handle from the parent process.
Import pyshell first in htest to call SetProcessDpiAwareness on Windows
before tkinter.Tk() is called for the htest. Apparently, 'root.destroy()'
undoes a previous 'root = Tk()'. Since IDLE unittests always destroy roots,
a unittest before an htest does not require anything more to work right.
Since part of the purpose of human-viewed tests is to determine that
widgets look right, it is important that they look the same for testing
as when running IDLE.
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.
Only make sure that the result is in unittest.signals._results, don't
check the full content of unittest.signals._results.
support._run_suite() uses TextTestRunner in verbose mode, but
TextTestRunner.run() calls registerResult(result) which made the test
fail with "odd object in result set".
Call also removeResult() to restore unittest.signals._results to
avoid test side effect.

Fix-up class name duplication in PR #7807. Combined effect is that
module calltips and its class CallTips are now calltip and Calltip.
In module calltip_w class CallTip is now CalltipWindow.

* 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.
In some development setups it is inconvenient or impossible to write bytecode
caches to the code tree, but the bytecode caches are still useful. The
PYTHONPYCACHEPREFIX environment variable allows specifying an alternate
location for cached bytecode files, within which a directory tree mirroring the code
tree will be created. This cache tree is then used (for both reading and writing)
instead of the local `__pycache__` subdirectory within each source directory.
Exposed at runtime as sys.pycache_prefix (defaulting to None), and can
be set from the CLI as "-X pycache_prefix=path".
Patch by Carl Meyer.
Create a template for minimally testing a tkinter-using module by importing it and instantiating its class(es). Add a test file for all non-startup IDLE modules. Edit existing files and update coverage. This is part 1 of 3, covering the 21 autocomplete to help modules and touching 33 idlelib files.
Fix "LC_ALL=C python3.7 -V": reset properly the command line parser
when the encoding changes after reading the Python configuration.
Fix pymain_read_conf(): use memset(0) to reset properly cmdline.
When Python is built with the intel control-flow protection flags,
-mcet -fcf-protection, gdb is not able to read the stack without
actually jumping inside the function. This means an extra
'next' command is required to make the $pc (program counter)
enter the function and make the stack of the function exposed to gdb.
Hangul composition check boundaries are wrong for the second character
([0x1161, 0x1176) instead of [0x1161, 0x1176]) and third character ((0x11A7, 0x11C3)
instead of [0x11A7, 0x11C3]).

* OSX: expose copyfile(3) instead of fcopyfile(3); also expose flags arg to python
* osx / copyfile: use path_t instead of char
* do not set dst name in the OSError exception in order to remain consistent with platforms which cannot do that (e.g. linux)

* use ctx manager for memoryview()
* update doc
* remove outdated doc
* remove last CopyFileEx remnants
* OSX - use fcopyfile(3) instead of copyfile(3)
...as an extra safety measure: in case src/dst are "exotic" files (non
regular or living on a network fs etc.) we better fail on open() instead
of copyfile(3) as we're not quite sure what's gonna happen in that
case.
* update doc
