Fix JSON reexport ICE #97599

Fixes #97432.

The problem was that the ID was conflicting because the reexports have the same one. To fix it, I "extended" it by adding the Symbol into it as well.

This is more like a bandage than a real solution.

You should look at #93518 which is a completely different approach than this PR is taking, basically the idea is for the JSON output to not inline any item like the html output is doing, meaning that re-exports will not ICE anymore because they will still be different and thus not have the same id.

Does that PR fix this bug? If so, then I'd like to merge that one instead.

That PR needs updated and is not yet perfect, it still has some known failures. On the other hand as far as I can tell it does fix re-export issues generally. I've been slacking on doing the work to carry it over the finish-line, I'd be willing to help mentor someone else if they are willing to do some of the work to push it over the finish-line, alternatively I'll try to set aside some time this weekend to finish it up.

I also took another approach at the start where I stopped inlining reexports but I found the result sub-optimal. However it'd be a better approach overall than my current PR.

What is missing in #93518?

What is missing in #93518?

It's currently blocked on fixing #93518 (comment) and applying this suggestion #93518 (comment). And maybe adding some more tests cases.

I see. Considering none of these PRs are anywhere close to being merged, should we move forward with this one then? I can add a FIXME: remove this function once no more inlining for JSON format above the from_item_id_with_name function to make sure it won't remain.

My problem here is that we have an ICE, which should be avoided at all cost.

I'd support moving forward with this as a future FIXME

Ok, updating the PR then. :)

Fix JSON reexport ICE

Fixes rust-lang#97432.

The problem was that the ID was conflicting because the reexports have the same one. To fix it, I "extended" it by adding the `Symbol` into it as well.
