My first fix is not enough to make test_bpo20891() reliable. A second
fix is needed and it was decided to not backport it, so remove the
test instead.
For Python 3.6, the workaround is to call PyEval_InitThreads() before
spawning the first C thread.
Python 3.7 will have both fixes.
Ensure that ``truncate()`` preserves the file position (as reported by ``tell()``) after writes longer than the buffer size..

Better account for single-line compound statements and
semi-colon separated statements when suggesting
Py3 replacements for Py2 print statements.
Initial patch by Nitish Chandra.
(cherry picked from commit 43c0f1ac5e)
Some tests failed when the PATH environment variable contained a path
to an existing file. Fix tests to ignore also NotADirectoryError, not
only FileNotFoundError and PermissionError.

The suggested replacement for print statements previously failed to account
for leading whitespace and hence could end up including unwanted text in
the proposed call to the print builtin.

This test doesn't care about order, the underlying filesystem APIs do not
guarantee directory listings on subsequent calls will be in the same order.

bpo-29240: On FreeBSD, if the LC_CTYPE locale is "C" or "POSIX",
writing and reading non-ASCII bytes into/from a TTY works,
but readline or ncurses ignores non-ASCII bytes on read.

Skip the test failing randomly because of known race condition.
Skip the test to fix macOS buildbots until a decision is made on the
proper fix for the race condition.

It no longer spends much time doing complex calculations and no
longer consumes much memory for creating large constants that will
be dropped later.
This fixes also bpo-21074.

* Fix spaces at the beginning of comments in test_logging.py.
(cherry picked from commit 53f7a7c281)
* fix issue32208: update threading.Semaphore docs and add unit test to validate correct behavior

The original algorithm tried to delegate the folding to the tokens so
that those tokens whose folding rules differed could specify the
differences. However, this resulted in a lot of duplicated code because
most of the rules were the same.
The new algorithm moves all folding logic into a set of functions
external to the token classes, but puts the information about which
tokens can be folded in which ways on the tokens...with the exception of
mime-parameters, which are a special case (which was not even
implemented in the old folder).
This algorithm can still probably be improved and hopefully simplified
somewhat.
Note that some of the test expectations are changed. I believe the
changes are toward more desirable and consistent behavior: in general
when (re) folding a line the canonical version of the tokens is
generated, rather than preserving errors or extra whitespace.

Previously, CO_NOFREE was set in the compiler, which meant
it could end up being set incorrectly when code objects
were created directly. Setting it in the constructor based
on freevars and cellvars ensures it is always accurate,
regardless of how the code object is defined.

When PyGILState_Ensure() is called in a non-Python thread before
PyEval_InitThreads(), only call PyEval_InitThreads() after calling
PyThreadState_New() to fix a crash.
Add an unit test in test_embed.
Enhance also embedded tests, backport from master:
* Add test_pre_initialization_api()
* Set PYTHONIOENCODING environment variable in
test_forced_io_encoding()
(cherry picked from commit b4d1e1f7c1)
* Fixed saving bytearrays.
* Identical objects will be saved only once.
* Equal references will be load as identical objects.
* Added support for saving and loading recursive data structures.
