`diesel_derives` panic when executed under rust-analyzer

[gwy15]

rust-analyzer will have proc macro panics when using latest diesel (v2.0+) as a dependency, even without any code.

rust-analyzer version: rust-analyzer 0.3.1248-standalone (0531aab 2022-10-16)

rustc version: fails both on latest stable and nightly: rustc 1.64.0 (a55dd71d5 2022-09-19) / rustc 1.66.0-nightly (a24a020e6 2022-10-18)

relevant settings: no special settings

Reproducible example:

# src/lib.rs
<blank>

# Cargo.toml
[package]
name = "play"
version = "0.1.0"
edition = "2021"

[dependencies]
diesel = { version = "2", features = ["mysql"] } # or postgres

BTW diesel 1.4 works fine in rust-analyzer

now, running cargo c is fine:

$ cargo c
   Finished dev [unoptimized + debuginfo] target(s) in 0.03s

but rust-analyzer panics

$ rust-analyzer analysis-stats .

This doesn't seem to crash rust-analyzer. The diesel AsExpression proc macro has an error and to report it, it panics. This is the only stable way to report errors. Rustc suppresses the panic backtrace and reports the panic message as regular error. Rust-analyzer doesn't seem to suppress anything, but after the panic happened it continued just fine like it should. If rust-analyzer itself crashed, the last couple of lines showing the actual analysis stats that you requested wouldn't show.

Thank you, but I don't see any rustc errors when running cargo check, is there any way that I can see the suppressed backtrace or the panic message as regular error?

I've narrowed the problem to this:
for this specific item,

    #[derive(FromSqlRow)]
    #[cfg_attr(feature = "mysql_backend", derive(AsExpression))]
    #[diesel(foreign_derive)]
    #[cfg_attr(feature = "mysql_backend", diesel(sql_type = crate::sql_types::Unsigned<BigInt>))]
    struct U64Proxy(u64);

when using cargo check, the diesel_derives crate proc macro gets this TokenStream when generating output TokenStream: (sync::DeriveInput)

#[diesel(foreign_derive)]
#[diesel(sql_type = crate :: sql_types :: Unsigned < BigInt >)] struct
U64Proxy(u64) ;

attributes tokens are: (syn::Attribute)

 derive input attr: (foreign_derive)
 derive input attr: (sql_type = crate :: sql_types :: Unsigned < BigInt >)

Notice here cfg_attr are processed and gone.
diesel_derives handles this fine.

---

But when using rust-analyzer, rust-analyzer feeds this to diesel_derives: (sync::DeriveInput)

#[cfg_attr (feature = "mysql_backend" , derive (AsExpression))] #[diesel (foreign_derive)] #[cfg_attr (feature = "mysql_backend" , diesel (sql_type = crate ::sql_types ::Unsigned <BigInt >))] struct U64Proxy (u64) ;

And when diesel_derives handles attributes, it gets this: (syn::Attribute)

 derive input attr: (feature = "mysql_backend" , diesel (sql_type = crate ::sql_types ::Unsigned <BigInt >))

diesel_derives cannot handle this.

So the problem here I think is rust-analyzer does not pre-process the cfg_attr attributes, which is different from the behavior of rustc?

Same error

[Sytten]

It used to be fine for us, but the bug seems to have reappeared recently on v0.4.1744 (testing for earlier versions to see where it broke):

[luckysori]

Are there any workarounds to this problem other than not using diesel_derives?

I see this very often and it does appear to crash the server for me (every time?), as opposed to what was said here: #13436 (comment).

I'm using diesel_derives v2.0.2 and rust-analyzer 1.74.0 (79e9716 2023-11-13).

[gwy15]

Are there any workarounds to this problem other than not using diesel_derives?

@luckysori personally, I only use the mysql feature. So I forked the diesel repo and modified all cfg_attrs, keeping only mysql-related attributes and removed all cfg_attrs. This is the best workaround I can think of by far.

[Veykril]

If it crashes rust-analyzer or the proc-macro server itself thats a different bug than what is being tracked here

Hmm, that's a good idea! Although that wouldn't quite work for us because we're using sqlite and postgres.

Fair enough. To be honest, I think I might be mistaken. The server crashes and Emacs' lsp-mode tells me to look for errors in a *rust-analyzer::stderr* buffer and all I can find is a bunch of these panics. But I've just verified that these panics are there even if the server hasn't crashed. False alarm most likely.

How would you go about debugging a crash like this given that the aforementioned error buffer does not seem to have the right data?
