Use `testdir.syspathinsert()` with multiprocessing tests:
- test_chained_exceptions_no_reprcrash
- test_exception_handling_no_traceback
This only works currently because `_importtestmodule` changes `sys.path`
as a side-effect.
It appears to be only required on Windows though - likely due to the
multiprocessing method used there.
Somehow in Python 3.5 on Windows this test fails with:
File "c:\hostedtoolcache\windows\python\3.5.4\x64\Lib\multiprocessing\connection.py", line 302, in _recv_bytes
overlapped=True)
OSError: [WinError 6] The handle is invalid
This only happens in this platform and Python version, decided to use
a dummy traceback as originally done in #6412.
(cherry picked from commit b9c136b809)
Tracebacks coming from remote processes crated by the multiprocess module
will contain "RemoteTracebacks" which don't have a 'reprcrash' attribute
Fix#5971
This methods were moved from xdist (ca03269).
Our intention is to keep this code closer to the core, given that it
might break easily due to refactorings.
Having it in the core might also allow to improve the code by moving
some responsibility to the "code" objects (ReprEntry, etc) which
are often found in the reports.
Finally pytest-xdist and pytest-subtests can use those functions
instead of coding it themselves.
