Create Error Infrastructure

[tsmaeder]

Coming out of discussions on #80, we should define common policies and infrastucture for reporting errors in ALM. Some features I would envision:

• Remember the context.Context at the time of creation
• Have a stack trace
• allow for nesting of errors (thus allowing for reconstruction of call stack and context chain)

Oh and yeah: 100th post!

damn it!! I've been doing Issue cleanup work for seemingly no good reason...

I read somewhere that one should still return "error" instead of more elaborate types, not sure why, though. Are interfaces assignement compatible in golang? Need to test.

Hi,
Has this been taken care of as part of https://github.com/almighty/almighty-core/pull/80/files , models/error.go Or are there more changes coming in ?

[tsmaeder]

No, the errors in that PR are an ad-hoc creation which lead to discussions about what requirements we have for error reporting.
