Error: "Connection got disposed" on eval

[Hu1buerger]

versions

Haskell extension v1.7.1. GHCi, version 8.10.7 Vscode:

Version: 1.62.2
Commit: 3a6960b964327f0e3882ce18fcebd07ed191b316
Date: 2021-11-11T20:59:05.913Z (5 days ago)
Electron: 13.5.2
Chrome: 91.0.4472.164
Node.js: 14.16.0
V8: 9.1.269.39-electron.0
OS: Darwin x64 20.6.0

How to reproduce

Assume the following code. Opened in Vscode as test.hs.

{-|
>>> add 1 2

}
add x y = x + y 

1. The extension will show Evaluate... on top of >>>add 1 2.
2. At first it is just stating evaluating without response.
3. Once clicked a new window pops up in the bottom right corner of the window
4. It states REDCROSS_IN_CIRCLE Connection got disposed

What I tried.

1. I tried to run the command >Haskell: Restart Haskell LSP Server
2. I rebooted the system

No fix as of now.

Hi, thanks for reporting the issue. As it is related with the lsp server, will move it to the haskell-language-server.
It would be great to have the lsp log when the error is reproduced, following the steps described here: https://github.com/haskell/vscode-haskell#troubleshooting

[Hu1buerger]

@jneira will do.

{-|
>>> add 1 2

}
add x y = x + y 

is actually a parse error because } does not close the block comment. Is that what was actually entered?

Fwiw, I can't reproduce using the nixos flake dev shell, ghc 8.10.7, hls commit 1b69975

[fishtreesugar]

I met same issue in MacOS Big Sur (11.6) and using homebrew built haskell-language-server ang GHC (8.10.7)

I noticed -- >>> import Prelude works fine, but -- >>> 1 + 1 or -- >>> a = 1 cause hls crash.
after doing some simple source code following, I found:

haskell-language-server/plugins/hls-eval-plugin/src/Ide/Plugin/Eval/CodeLens.hs

Line 499 in e1949dd

res <- exec stmt l

haskell-language-server/plugins/hls-eval-plugin/src/Ide/Plugin/Eval/CodeLens.hs

Lines 523 to 525 in e1949dd

	exec stmt l =
	let opts = execOptions{execSourceFile = fp, execLineNumber = l}
	in myExecStmt stmt opts

haskell-language-server/plugins/hls-eval-plugin/src/Ide/Plugin/Eval/Code.hs

Lines 90 to 93 in e1949dd

	myExecStmt :: String -> ExecOptions -> Ghc (Either String (Maybe String))
	myExecStmt stmt opts = do
	(temp, purge) <- liftIO newTempFile
	evalPrint <- head <$> runDecls ("evalPrint x = P.writeFile "<> show temp <> " (P.show x)")

myExecStmt is called newTempFile, and I can see temp file like extra-file-12162067389-64378-3 presented and empty, but not deleted. so my guessing is hls crash at calling runDecls

declaration case call runDecls too

haskell-language-server/plugins/hls-eval-plugin/src/Ide/Plugin/Eval/CodeLens.hs

Lines 513 to 516 in e1949dd

	do
	dbg "{DECL " stmt
	void $ runDecls stmt
	return Nothing

but runDecls is GHC api, I don't have farther ability to debug it.

@jneira hope it could help

may related to #2000

Yeah I do think it's related to linking because it seems to be Mac specific and the eval plugin depends on how libraries are linked.

I've been having the same issue. I started using HLS in vscode last summer. Everything worked fine until a week ago or so. Since then, evaluating expressions results in the "Connection got disposed." message most of the time. After trying several times, I get "The Haskell server crashed 5 times in the last 3 minutes. The server will not be restarted.".

The strange thing is that it still works some of the time, maybe 1 in 20 tries. Maybe there is some race condition?

Here is the log recording one such event (with "Haskell > Trace :Client" set to "debug"): hls.log

I started vscode at 00:55:38 and clicked on the evaluation code lens at 00:56:02. It looks like the actual evaluation executes successfully, but then HLS exits with code -11 and vscode tries to access the dead connection? I'm not entirely sure what's happening here.
