Shouldn't these be TypeErrors?

{type} should be added.

Better, but all common.expectsError need {type} (since before the RegEx did assert the Type as part of the message).

Addressed and rebased

💯

refack · 2017-06-21T13:13:55Z

Just found #11317.
But IMHO this PR's approach is better

BridgeAR · 2017-06-21T13:26:12Z

@refack I tried to find a duplicate and I didn't find that one... I am fine to remove the overlapping changes here. I guess that would be best?

BridgeAR · 2017-06-21T13:28:50Z

Oh, #11317 was closed when I was looking for it. That's why I couldn't find it 😃

I don't think flags need a special error code.

this change looks entirely unrelated to the internal/errors change... it should likely be in it's own PR

~~I think it is pretty much a leftover of a former change. I'll remove it again~~

I had another look at it and I changed it to original because the error is thrown with original and not orig. I originally changed the error but @refack suggested to change the variable name instead as the documentation also speaks of original.

Having a specific ERR_UNKNOWN_ENCODING error would be better here.

I believe this and the flags assertion are superseded by #11317
(Where I made the opposite argument 😉 #11317 (comment) )

I think I agree that sticking to the generic one makes sense, but open discussion on the merits of a more specific one.

ERR_FS_UNKNOWN_FILE_OPEN_FLAG or something similar

refack · 2017-07-09T22:34:18Z

@BridgeAR now that the other PRs landed, could you rework & rebase. Probably could use the new expectsError(fn, options) in allot of these places.

Needs rework to use newly landed ERR codes

Can you rebase? This is conflicting with master.

In addition refactor common.throws to common.expectsError

BridgeAR · 2017-07-22T21:18:59Z

There is not much left of this after a couple of rebases as there were other PRs that got merged that did the same thing. This is happening very frequently with the internal/errors and I am wondering how it's possible to prevent these duplicates a bit better. I actually stopped opening PRs with ports because of that.

I squashed the commits as they individually did not change a lot anymore.
