#6334: Fix summary entries appearing twice when f/F and s/S report chars were used at the same time in the -r command-line option (for example -rFf).
The upper case variants were never documented and the preferred form should be the lower case.
#7310: Fix UnboundLocalError: local variable 'letter' referenced before assignment in _pytest.terminal.pytest_report_teststatus()
when plugins return report objects in an unconventional state.
This was making pytest_report_teststatus() skip
entering if-block branches that declare the letter variable.
The fix was to set the initial value of the letter before
the if-block cascade so that it always has a value.
#6870: New Config.invocation_args attribute containing the unchanged arguments passed to pytest.main().
Remark: while this is technically a new feature and according to our policy it should not have been backported, we have opened an exception in this particular case because it fixes a serious interaction with pytest-xdist, so it can also be considered a bugfix.
#5477: The XML
file produced by --junitxml now correctly contain a <testsuites>
root element.
#6044: Properly
ignore FileNotFoundError (OSError.errno == NOENT in Python 2)
exceptions when trying to remove old temporary directories, for
instance when multiple processes try to remove the same directory
(common with pytest-xdist for example).
#4344: Fix RuntimeError/StopIteration when trying to collect package with "init.py" only.
#5478: Fix encode error when using unicode strings in exceptions with pytest.raises.
#5524: Fix issue where tmp_path and tmpdir would not remove directories containing files marked as read-only,
which could lead to pytest crashing when executed a second time with the --basetemp option.
#5547: --step-wise now handles xfail(strict=True) markers properly.
#5650: Improved output when parsing an ini configuration file fails.
