regrtest now uses sys.unraisablehook() to mark a test as "environment
altered" (ENV_CHANGED) if it emits an "unraisable exception".
Moreover, regrtest logs a warning in this case.
Use "python3 -m test --fail-env-changed" to catch unraisable
exceptions in tests.
Use catch_unraisable_exception() to ignore 'Exception ignored in:'
error when the internal BufferedWriter of the BufferedRWPair is
destroyed. The C implementation doesn't give access to the
internal BufferedWriter, so just ignore the warning instead.
* bpo-29505: Enable fuzz testing of the json module, enforce size limit on int(x) fuzz and json input size to avoid timeouts.

Rename compile() feature_version parameter to _feature_version and
convert it to a keyword-only parameter.
Update also test_type_comments to pass feature_version as a tuple.
When the line is uncommented, the equals character causes it to be incorrectly interpreted
as a macro definition by makesetup. This results in invalid Makefile output.
The expat code only requires XML_POOR_ENTROPY to be defined; the value is unnecessary.
Fix an unintended ValueError from :func:`subprocess.run` when checking for
conflicting `input` and `stdin` or `capture_output` and `stdout` or `stderr` args
when they were explicitly provided but with `None` values within a passed in
`**kwargs` dict rather than as passed directly by name.
Currently, inspect.getfile(str) will report nonsense:
```pytb
>>> inspect.getfile(str)
TypeError: <module 'builtins' (built-in)> is a built-in class
```
This fixes that

There is a possibility that someone (like me) accidentally will omit parentheses with `FileType` arguments after `FileType`, and parser will contain wrong file until someone will try to use it.
Example:
```python
parser = argparse.ArgumentParser()
parser.add_argument('-x', type=argparse.FileType)
```

Replace two Python function calls with a single one to ensure that no
memory allocation is done between the invalid object is created and
when _PyObject_IsFreed() is called.
* bpo-36520: reset the encoded word offset when starting a new
line during an email header folding operation
* 📜🤖 Added by blurb_it.
* bpo-36520: add an additional test case, and provide descriptive
comments for the test_folding_with_utf8_encoding_* tests
* bpo-36520: fix whitespace issue
* bpo-36520: changes per reviewer request -- remove extraneous
backslashes; add whitespace between terminating quotes and
line-continuation backslashes; use "bpo-" instead of
"issue #" in comments
In test_fromkeys() the derived test class now supports all arguments in its
constructor so that the class to be tested can use its own constructor in its
fromkeys() implementation.
In test_mutatingiteration() the test fails as soon as iterating over a
dictionary with one entry and adding new entries in the loop iterates more
than once (to avoid endless loops in faulty implementations).
