Nathaniel J. Smith e46a8af450 bpo-30579: Allow TracebackType creation and tb_next mutation from Python (GH-4793) 
Third party projects may wish to hide their own internal machinery in
order to present more comprehensible tracebacks to end users
(e.g. Jinja2 and Trio both do this).

Previously such projects have had to rely on ctypes to do so:

  fe3dadacdf/jinja2/debug.py (L345)
  1e86b1aee8/trio/_core/_multierror.py (L296)

This provides a Python level API for creating and modifying real
Traceback objects, allowing tracebacks to be edited at runtime.

Patch by Nathaniel Smith.

Serhiy Storchaka f15c4d374a bpo-20548: Use specific asserts in warnings and exceptions tests (#788) 2017-03-30 18:05:08 +03:00

Zachary Ware 38c707e7e0 Issue #21741: Update 147 test modules to use test discovery. 
I have compared output between pre- and post-patch runs of these tests
to make sure there's nothing missing and nothing broken, on both
Windows and Linux.  The only differences I found were actually tests
that were previously *not* run.

Amaury Forgeot d'Arc db26f7c137 Issue 3611: in some cases (a __del__ re-raising an exception, when called from inside 
an 'except' clause), the exception __context__ would be reset to None.
This crases the interpreter if this precisely happens inside PyErr_SetObject.

- now the __context__ is properly preserved
- in any case, PyErr_SetObject now saves the current exc_value in a local variable, to
avoid such crashes in the future.
