Steps to reproduce

1. Open up VS Code (for this repo)
2. Observe that it takes a long time for all extensions to activate, including HLS

Expected behaviour

Popup saying e.g. "Resolving dependencies..."

Actual behaviour

No extensions activate, stuff like saving a file hangs; all waiting for HLS to finish its cabal cradle operation (which is busy doing "Resolving dependencies...").

Include debug information

Execute in the root of your project the command haskell-language-server --debug . and paste the logs here:

A simpler way to reproduce this may be to open a project that uses a cabal cradle, while replacing the cabal executable with a script containing:

echo Resolving dependencies...
sleep 60

and observing that the HLS extension does not activate, and that it blocks other extensions from activating.

[jneira]

Hi, thanks for the detailed bug report. I agree that we should show some kind of feedback while hls is loading the cradle.
We are showing in the status bas a progress notification while loading files and indexing it in the hiedb, is not showing anything while cabal/stack is building?

and that it blocks other extensions from activating.

Afaics the haskell syntax extension is activated quite fast, without waiting for the full loading of the file, what other related (or not) extensions are being blocked?

[runeksvendsen]

We are showing in the status bas a progress notification while loading files and indexing it in the hiedb, is not showing anything while cabal/stack is building?

After further analysis, I think the problem may be that getting project GHC version can be really slow. Here's an example of it taking more than a minute (with the aforementioned repo):

$ time /Users/rune/Library/Application\ Support/Code/User/globalStorage/haskell.haskell/haskell-language-server-wrapper-1.2.0-darwin --project-ghc-version
Found "/Users/rune/Obsidian/iohk/code/os-voltaire-fork/cardano-node/hie.yaml" for "/Users/rune/Obsidian/iohk/code/os-voltaire-fork/cardano-node/a"
 --project-ghc-version  61.78s user 1.15s system 98% cpu 1:04.13 total

Given that this takes so long, launchHaskellLanguageServer should also be slow to finish, since it also attempts to find the GHC version at startup. Perhaps all cabal-related operations should be async, and provide some sort of progress notification (as e.g. building and indexing does)?

Afaics the haskell syntax extension is activated quite fast, without waiting for the full loading of the file, what other related (or not) extensions are being blocked?

It's not quite deterministic, unfortunately. I've experienced e.g. the smooth scroll extension not activating until HLS is done starting up. Yesterday I experienced VS Code being really slow to save a file ("File create action", I believe the title of the progress dialog was) while HLS was starting up.

I think this is related to dependency resolution being slow for this repo, as it's the only repo I've worked with that has both really slow dependency resolution and makes the VS Code GUI hang on startup.

[runeksvendsen]

It appears the problem is that the cabal v2-exec command does dependency resolution before running the GHC command. So, running the command

cabal v2-exec --with-compiler <path_to_ghc> ghc -v0 -- --numeric-version

(which HLS runs on startup to find the project's GHC version) will take as long to finish as it takes cabal to resolve dependencies, which can be a very long time (e.g. in the case of the https://github.com/input-output-hk/cardano-node repo).

[jneira]

Many thanks for the further investigation. It seems when the extension calls cabal/stack to "simply" determine what ghc version is being used by the project, no progress indicator is being emitted
We have to add that prgress notification in the extension with an informative message ("Determining haskell-language-server version" or something similar)

[runeksvendsen]

I agree that's a good idea. However, it would also be nice if we could issue a cabal command that finds the correct GHC version without requiring dependency resolution. As far as I can see, it's not necessary for cabal to resolve dependencies before reporting back which GHC version it's using.

On my system, HLS runs the command below to find the GHC version, which takes 60 seconds for the cardano-node repo:

$ time cabal v2-exec --with-compiler /Users/rune/.cache/hie-bios/wrapper-13a09b18ea883dd377d59db5e821a86b ghc -v0 -- --numeric-version
8.10.4
cabal v2-exec --with-compiler  ghc -v0 -- --numeric-version  61.89s user 1.00s system 98% cpu 1:03.79 total

Is there a reason we can't just execute the GHC script whose path is passed to cabal via the --with-compiler switch above (/Users/rune/.cache/hie-bios/wrapper-13a09b18ea883dd377d59db5e821a86b) and pass it the --numeric-version argument like below?

Running this takes a fraction of the time:

$ time /Users/rune/.cache/hie-bios/wrapper-13a09b18ea883dd377d59db5e821a86b --numeric-version
8.10.4
/Users/rune/.cache/hie-bios/wrapper-13a09b18ea883dd377d59db5e821a86b   0.05s user 0.04s system 49% cpu 0.173 total

good question, the code making that call is in hie-bios, to investigate (maybe @fendor remember that part faster)
