fpoli · 2018-07-09T13:31:39Z

As in the tagged issue, the question here is whether the current implementation ignores the callsite of macro expansions on purpose or not.

From the tests it looks that yes, some tests expect the error to be reported inside the macro definition. If this works as intended I can close the PR and that's all.

However, if the test calls a macro from a library and an error arises from the macro expansion, then there is no way to write the //~ bla comment in the test to expect the error. In some cases it can be confusing.

That said, this pull request would still require some fixes because on some tests it doesn't match the expected error. Maybe span expansions are not used just for macros?

TimNN · 2018-07-17T17:58:14Z

Ping from triage, @alexcrichton: This PR requires your review.

alexcrichton · 2018-07-17T21:11:02Z

Oh dear sorry for the delay!

I don't personally know much about spans/diagnostics, but this does look like we may not want to change it due to the number of failing tests? For UI tests as have the full output anyway to match against, so this is largely an issue for compile-fail tests which we're migrating over time to UI tests I think.

@fpoli do you still want to land this PR as-is after fixing up some tests? Or were you thinking of taking an alternate strategy?

fpoli · 2018-07-18T13:12:30Z

I think that the number of failing tests is not a problem: usually the fix requires to move the //~ comment to a different line and it's easy. If it's fine I can start fixing the tests.

petrochenkov · 2018-07-19T09:38:25Z

For tests in which new //~ ERROR annotations are now required (errors from macros from other crates) this is an important fix for a long-standing issue, but for other tests it's a regression because //~ ERROR annotations are now placed on different lines than errors actually appear in the output (this can be seen in UI tests).

Also see #52531 which is somewhat relevant.

For macros we should ideally go up the macro call stack until we are in the current file, but then stop.

For macros we should ideally go up the macro call stack until we are in the current file, but then stop.

That's a great suggestion, quite easy to implement I think. I'll try

Done. Existing //~ ERROR annotations stay where they are, so it's not a regression. For errors generated in external macros, it's now possible to write an //~ ERROR annotation that expect them.

Overall, I think that the tests are strictly better.

fpoli · 2018-07-21T07:11:34Z

With this PR the test suite no longer ignores some errors, which is good, but existing tests need to be updated with more `//~ ERROR` annotations. How can I reproduce these tests locally? `./x.py test [--bless]` seems to be not enough.

petrochenkov · 2018-07-21T12:37:31Z

Travis passed, so this seems to be a Windows-specific error.
Perhaps self.file_name == file_name fails due to / vs \ mismatch or something.

I attempted a fix for the failing tests on windows, but I'm not super confident because I don't have a windows machine on which to run the tests. I'm waiting for my own execution of the tests on AppVeyor.
