looks like that.
i am using the crate bevy, and when i use some macros there comes the crash:

looks like it is saying 'the pipe is closing',but i dont know how it means.
i tried to restart the RA event the computer but not working.

Can't reproduce in 0.3.1541. Do you have any settings like rust-analyzer.server.path?

[Veykril]

That's using yesterdays rust nightly proc macro server, I wonder did something go wrong with the subtree sync?

[lnicola]

Oh, right, I had the previous nightly. Oof.

[Veykril]

-in-rust-tree = [
    "proc-macro-srv/sysroot-abi",
    "ide/in-rust-tree",
    "syntax/in-rust-tree",
]
+sysroot-abi = ["proc-macro-srv-cli/sysroot-abi"]
+in-rust-tree = ["sysroot-abi", "ide/in-rust-tree", "syntax/in-rust-tree"]

This is the only diff part that seems relevant, but this should work fine no? Only difference is the intermediate feature flag but to my knowledge that will pass through properly right?

[Veykril]

@zerodegress you can get around this by downgrading your toolchain to a version from before yesterday for now

I think the proc macro server gets built with proc-macro-srv/sysroot-abi, but without sysroot-abi? But the panic is in proc-macro-srv-cli.

[Veykril]

Ah, that explains it. proc-macro-srv-cli was previously a dependency of proc-macro-srv https://github.com/rust-lang/rust-analyzer/pull/14432/files#diff-90bc501a1b3268c21aa349b968f706e31ac022ddb76b05eb675ca44066eb1ecb

So no subtree problems, we just need to update the build step

Thanks, it realy works.
hope this be fixed soon.

Fixed in the 2023-06-08 nightly toolchain.
