[elbe-devel] [PATCH 0/3] elbepack: introduce cli exception handling framework

[Thomas Weißschuh]

The current practice of sprinkling explicit calls to sys.exit() all
through the codebase has various issues:

* The stacktrace is always lost, making debugging harder
* Code calling sys.exit() is non-composable
* Any changes to the error-reporting have to applied all over the codebase

Introduce a new reporting framework which works through sys.excepthook
and a small helper to attach additional information to arbitrary exceptions.
This helper avoids the mentioned pitfalls.

It also preserves the possibility for per-error exitcodes and allows a
stepwise migration process.

In addition, other exceptions that have no explicit handling set up,
while currently printing a enduser-unfriendly stacktrace now
automatically use nicer formatting.
