[Error - 12:20:13] Request textDocument/hover failed.
Message: server panicked: index out of bounds: the len is 1 but the index is 1
Code: -32603
According to the trace, this occurred when hovering over the pp::$0Printer part of this line:
https://github.com/rust-lang/rust/blob/13edc17f65bcad7fe9046720a16fc192e810970e/compiler/rustc_hir_pretty/src/lib.rs#L83
That doesn't trigger the panic for me, so there might be local changes that shift the line/column numbers around
@jonas-schievink can we write a better assertion message here? Or maybe add something else to the panic context?
On a meta level, I don't think we will be very successful at reproducing the exact panics the user sees, as that needs in-memory state of the documents, and also the ability to cargo metadata the overall project.
That being said, with our current architecture, I don't think it would be too too hard to add something which dumps all salsa inputs at the moment of the panic into a ~100mb file which gives us a repro. I don't think we should do that due to the privacy concerts though.
So, I'd love us to really be able to look at the panic message, and be able to reverse-engineer the failing input, like in #10083.
I've opened https://github.com/rust-analyzer/rust-analyzer/pull/10095 to add more debugging info here
Just got this same panic today, in the middle of writing some fairly innocuous code. Something along the lines of Blah<Future = BoxFuture<.... Cleaning and restarting server didn't fix it. Deleted that line of code, everything worked. For some reason it's really not liking this BoxFuture, panics every time I put it back.
Side note: shout out to all the contributors, y'all have done a fabulous job, first stability problem in a long time, and tool is really fantastic.

@starkat99 that looks like https://github.com/rust-analyzer/rust-analyzer/issues/10046
Just ran into this while hacking on salsa:

thread '<unnamed>' panicked at 'index out of bounds: the len is 1 but the index is 3', crates/hir_def/src/nameres/path_resolution.rs:394:33
And managed to reproduce this once by hovering over Ident here, but a subsequent server restart made it no longer reproduce...
I have no idea why hovering over anything in on_demand_inputs.rs would make us try to resolve Ident though.
I'm currently getting this error a bunch with RA Nightly. Here's a dump of all the output in the VSCode output panel:

We're trying to get the trait implemented by this serde-yaml impl (which is None, of course). We query the impl's self type, Deserializer<'a>, and resolve that.
Now for some reason, it is using the DefMap of the test_de test in serde-yaml (which only has 1 module) to resolve Deserializer, but from a module that isn't part of this DefMap.
This still makes no sense at all to me, so I added some more info to the context in https://github.com/rust-analyzer/rust-analyzer/pull/10185. @jplatte do you by any chance remember what triggered these panics? I'm still not having any luck reproducing this locally.
I was working on https://github.com/matrix-org/matrix-rust-sdk/pull/309. Maybe you can fudge around with the code introduced by the second-to-last commit there? I think when writing that I got this (but also earlier when working on the same PR).
Either way I'm probably going to work on a followup PR to that in the next days so chances seem high that I'll trigger the bug again 😄
Got the panic again, dump:

Panicking whenever hovering the Option here in my current session https://github.com/rust-analyzer/rust-analyzer/blob/516eb40ba5b9d20e59e98185d1b2fcba5599ef7a/crates/base_db/src/fixture.rs#L91
Interestingly enough, the output of the debug prints you added differs on each panic... and if triggered often enough it stops panicking.

[Error - 오전 12:57:31] Request textDocument/hover failed.
Message: server panicked: index out of bounds: the len is 1 but the index is 1
Code: -32603
I re-hovered the ident until it stopped panicking at which point it worked normally, here is the entire panic log for this https://gist.github.com/Veykril/9c189877bb965b006bdd0eefa5570ec5
Edit: Just ran into this again, this time hovering std's Arc, at which point hovering any type or trait of std caused the panic.
Same issue for me.
Log: https://gist.github.com/f32by/4ed1151cdb5a71e39fc0d46970fb540a
Panicking when hovering AsRef and Display in following code snippet.
impl<T> ExpectLogError<T> for Option<T> {
#[inline]
fn expect_log_err<S>(self, msg: S) -> T
where
S: AsRef<str> + fmt::Display,
{
match self {
Some(v) => v,
None => panic_with_log!(msg),
}
}
}
After adding some asserts for myself and having fortunately triggered some of them it seems like the tuple in the vec![(def_map.clone(), self.local_id)]; here
https://github.com/rust-analyzer/rust-analyzer/blob/c577e128fc3aa9d5cf113c24c7f425e2b68bb2b6/crates/hir_def/src/resolver.rs#L739-L753
is incorrect.
Unfortunately forgot to save the stracktrace but the previous call was <hir_def::ImplId as hir_def::resolver::HasResolver>::resolver and then its basically the same stacktrace as the other ones.
So we are somehow creating an invalid module_id in an ImplLoc somewhere which doesn't really make sense... or the def_map query is incorrect.
Yeah, I've looked at the code in hir_def and couldn't find anything that looked wrong (most APIs in there make it very hard to mismatch IDs like that).
It looks to me like something outside of hir_def is causing the problem. Almost as if the data interned in the salsa database gets corrupted or mixed up somehow.
Not sure whether more backtraces are useful, but here is another one and I actually had a closer look. The type being referenced (that's supposed to be resolved?), UnsupportedError, is one that I have no idea where it could come from because that string is not found within the entire codebase I'm working on. Full error:

[Error - 12:43:13 PM] Request textDocument/hover failed.
Message: server panicked: index out of bounds: the len is 1 but the index is 1
Code: -32603
I ran into this when hovering String in an Enum declaration. The code is private, so I can't share the full context, but the block I was looking at looked like this (hovering the String part of the Identifier variant):
#[derive(Debug, Eq, PartialEq)]
enum ContextPredicate {
Identifier(String),
Equal(String, String),
NotEqual(String, String),
Not(Box<ContextPredicate>),
And(Box<ContextPredicate>, Box<ContextPredicate>),
Or(Box<ContextPredicate>, Box<ContextPredicate>),
Just(bool),
}

Out of curiosiosity, but does everyone here who ran into this issue before this monday have rust-analyzer.experimental.procAttrMacros enabled? For the people that have had this happen since this tuesday, are you running the nightly rust analyzer version?
I can't shake the feeling for some reason that this is attribute macro related so I wanna confirm this.

I have rust-analyzer.procMacro.enable enabled and rust-analyzer.experimental.procAttrMacros disabled.
Just checked and I was on the stable channel.
I have the same as @cherryleafroad, rust-analyzer.procMacro.enable is on and rust-analyzer.experimental.procAttrMacros is off.
Also, I'm not sure if it's helpful, but for me the only times I've seen this error manifest is on types from the Standard Library. Hovering over a type from my own crate or a crate dependency works fine, but hovering over std types fails (I've seen it with String, Option, Arc, File, Command, OsString, AtomicBool, Ordering). Primitive types like f32, bool, and usize seem to work fine, as does hovering over a module name to get the module-level documentation. It's only the concrete types that cause issues.
It's only the concrete types that cause issues. That is because the actual panic occurs when fetching implementations of types(and traits), but I've also only seen this happen on std items so far, never on a workspace crate or other dependency.
If this helps anyone, it did this a lot to me (every single ctrl button press, literally) when I was ctrl+z'ing a lot of code. (In this case, ctrl+z was undoing one of my use statements)
It might also help to know that I set this option: "files.autoSave": "afterDelay",, which means it's going to be calling Rust Analyzer A LOT
Other options
"rust-analyzer.procMacro.enable": true,
"rust-analyzer.lens.references": true,
"rust-analyzer.hoverActions.references": true,
"rust-analyzer.experimental.procAttrMacros": true,
"rust-analyzer.checkOnSave.enable": true,
"rust-analyzer.diagnostics.enable": true,
"rust-analyzer.updates.channel": "nightly",
(note that most of these were different before and it was still happening; I was on stable, and diagnostics, checkon save, and procattrmacros were all off; all other ones were likely enabled all this time) - I have switched to nightly since then - not that it changed anything for me.
I have investigated this issue further and it does indeed look like a bug in salsa's interning code. Updating salsa to include https://github.com/salsa-rs/salsa/commit/f7dd6b3219b25a5cdc1ab09c94574a8c2432bbb7 does no longer trigger my assertions and should hopefully fix this issue too.
Hmm. I am still casually getting this panic (even with the fix in #10479). I wasn't able to reduce the code to something reproducable but I'll try...
