-Zui-testing was lost during revert.

It doesn't work at all. Whatever I try to do, I always end with empty stderr so I'll keep my code for the moment.

Ah nevermind, I didn't update correctly...

petrochenkov · 2018-03-03T00:51:02Z

Could you split this into revert commits for 9b597a1 and 1dc2015 and commit with actual new implementation?

Also UI test outputs need to be regenerated.

-Zui-testing was lost during revert. [...] split this into revert commits for 9b597a1 and 1dc2015

@GuillaumeGomez I think I got the restoration of -Zui-testing right in #48621?—in case you would rather cherry-pick those commits rather than re-authoring similar commits from scratch yourself. (git revert 9b597a1 and git revert 1dc2015 both result in conflicts that need to be fixed manually.)

src/librustc_errors/emitter.rs

While this does successfully implement #48041, it seems rather ad hoc to make a show_explain method be part of the contract of the Emitter trait. (In contrast to how it makes sense for all Emitters to have an emit method, because that's what being an Emitter is all about.) Can we implement this in a more generalizable way?

Two potential alternatives that come to mind:

Make the Emitter trait have a destination method that exposes something we can write arbitrary lines to, and use it to write the --explain usage message in abort_if_errors.

JsonEmitter's dst field is of type Box<Write + Send>, and EmitterWriter's Destination implements Write and the field of all three of its variants implement Send (visible in the source in the case of BufferedTerminal and Raw, and the term docs say that StderrTerminal is Send), so I think the types should check out.

Implement the --explain message as a Diagnostic, adding a plainer formatting mode to Diagnostic if necessary.

@GuillaumeGomez can you comment on this?

zackmdavis · 2018-03-03T03:21:18Z

src/libsyntax/json.rs

As I mentioned in passing at the end of a previous comment, Handler already knows what what codes we've emitted; JsonEmitter shouldn't have to know this.

Oh indeed. I'll remove this add.

(If we end up needing to regenerate the UI test expectations anyway in the course of this PR, then we might as well also update the language (and use backticks) at the same time; but if not, then we can continue leave those tasks to #48559.)

@petrochenkov: Tests (finally) passed.

src/test/ui/associated-type-projection-from-multiple-supertraits.stderr

Last thing: removing this trailing empty line and the empty line after "Some errors occurred...", then we'll land this with higher priority.

GuillaumeGomez · 2018-03-13T16:54:00Z

@petrochenkov: Done as well, but let's wait for CI confirmation first.

GuillaumeGomez · 2018-03-13T23:53:57Z
