|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4173: Use core instead of std for builtin derive macros r=edwin0cheng a=edwin0cheng Fixed #4087. We can't use `$crate` here right now because : 1. We have to able to detect `macro` 2.0 in collecting phase for finding `rustc_builtin_macro` attrs. 2. And we have to make hygiene works for builtin derive macro. r= @flodiebold Co-authored-by: Edwin Cheng <[email protected]>

This is perhaps a bit circuitous, but it does actually get the job done. The result of this change is that once RA is finished its initial loading of a project, goto-definition requests are instant. There don't appear to be any more surprise latency spikes. This _partially_ addresses #1650 in that it front-loads the latency of the first goto-definition request, which in turn makes it more predictable and less surprising. In particular, this addresses the use case where one opens the text editor, starts reading code for a while, and only later issues the first goto-definition request. Before this PR, that first goto-definition request is guaranteed to have high latency in any reasonably sized project. But after this PR, there's a good chance that it will now be instant. What this _doesn't_ address is that initial loading time. In fact, it makes it longer by adding a phantom goto-definition request to the initial startup sequence. However, I observed that while this did make initial loading slower, it was overall a somewhat small (but not insignificant) fraction of initial loading time. ----- At least, the above is what I _want_ to do. The actual change in this PR is just a proof-of-concept. I came up with after an evening of printf-debugging. Once I found the spot where this cache priming should go, I was unsure of how to generate a phantom input. So I just took an input I knew worked from my printf-debugging and hacked it in. Obviously, what I'd like to do is make this more general such that it will always work. I don't know whether this is the "right" approach or not. My guess is that there is perhaps a cleaner solution that more directly primes whatever cache is being lazily populated rather than fudging the issue with a phantom goto-definition request. I created this as a draft PR because I'd really like help making this general. I think whether y'all want to accept this patch is perhaps a separate question. IMO, it seems like a good idea, but to be honest, I'm happy to maintain this patch on my own since it's so trivial. But I would like to generalize it so that it will work in any project. My thinking is that all I really need to do is find a file and a token somewhere in the loaded project, and then use that as input. But I don't quite know how to connect all the data structures to do that. Any help would be appreciated! cc @matklad since I've been a worm in your ear about this problem. :-) Co-authored-by: Andrew Gallant <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit makes RA more aggressive about eagerly priming the caches. In particular, this fixes an issue where even after RA was done priming its caches, an initial goto-definition request would have very high latency. This fixes that issue by requesting syntax highlighting for everything. It is presumed that this is a tad wasteful, but not overly so. This commit also tweaks the logic that determines when the cache is primed. Namely, instead of just priming it when the state is loaded initially, we attempt to prime it whenever some state changes. This fixes an issue where if a modification notification is seen before cache priming is done, it would stop the cache priming early.
