HIE doesn't work after build. "haskell-lsp: Failed to parse message header" error

[mingcenwei]

I attempted to build HIE with stack from source on my macOS Catalina. The executables were successfully installed to ~/.local/bin. However, whenever I run hie (or hie-wrapper), the program will block after displaying the line 2019-12-XX XX:XX:XX.XXXXXX [ThreadId 4] - args:[]. Then if I press any key, the program will crash (and print hie-wrapper: callProcess: /Users/say/.local/bin/hie-8.6.5 (exit 1): failed if I use hie-wrapper rather than hie). If I add the flags --lsp --debug, the program will block after displaying the line haskell-lsp:Starting up server ..., and crash if I press any key and print the message:

2019-12-26 01:28:33.947057 [ThreadId 4] -
haskell-lsp: Failed to parse message header:
: string
 exiting 1 ...

(^ The program gets stuck.)

(^ It crashes if I press any key.)

The Haskell Language Server extension on Visual Studio Code doesn't work, either. It's continually emitting the following error messages:

The following are the last few lines written to the standard output after I run stack repl haskell-ide-engine in the build directory:

[fendor]

Thank you for the detailed bug report!
I think you are running into multiple issues here. First, hie communicates with the lsp-client via stdin. So, if you enter anything, hie expects it to be a well-formed lsp message, which it is not, therefore not a bug.
Another issue is that it seems currently impossible to use stack repl in haskell-ide-engine itself, which crashes hie and produces this weird error message: cannot satisfay -package z-haskell-ide-engine-z-test-utils. Currently, it is easier to work on hie with cabal.
On which project did you execute hie? E.g. in which project did vscode emit the error messages? And which files did you open? I think you are also running into #1495, meaning that hie implicitly tries to use ghc 8.8.1 for which we have no support. The current effort to fix #1495 is in #1496.

EDIT: One last thing, does the project build with just stack build?

[alanz]

Also, make sure you are using current master, for a while we had a version that errored if it received the --lsp command line flag, which has been required up to now. Current master accepts it, as a nop, for backward compatibility.

[mingcenwei]

@fendor Thanks for your prompt explanation!
I just created a sample project using the command stack new test. It uses the default template "new-template" of stack, which can be directly built with just stack build:

>$ tree test/
test/
├── ChangeLog.md
├── LICENSE
├── README.md
├── Setup.hs
├── app
│   └── Main.hs
├── package.yaml
├── src
│   └── Lib.hs
├── stack.yaml
├── test
│   └── Spec.hs
└── test.cabal

3 directories, 10 files

Precisely, the following script can reproduce my problem on my computer:

#!/usr/bin/env bash

cd $(mktemp -d)
stack new test
cd test
code .    # open this directory in VS Code

If I open any one of the files Setup.hs, Main.hs, Lib.hs, Spec.hs in VS Code, then after some time the error messages will appear.

[mingcenwei]

@alanz Yes, I'm using the current master. I git-cloned it and built it yesterday.

[mingcenwei]

This is the log file of the VS Code extension:
vs-code-haskell-language-server-log-file.log

[fendor]

Opening Setup.hs will not work because that is a special file that is executed by Cabal. But the others need to work as expected.

You are using the implicit cradle discovery mechanism, also called, cabal-helper. This mechanism has a bug: mpickering#47.
tldr: Initial build of project does not generate enough files and is this happens because of this long standing bug haskell/cabal#2209 and our attempt to fix this is haskell/cabal#6441. However, it is a bit more complex to fix and will take some time to get right.
Work around: Initially build the project, e.g.

#!/usr/bin/env bash

cd $(mktemp -d)
stack new test
cd test
stack build # initial build
code .    # open this directory in VS Code

then open app/Main.hs.
This fixes the problem from above for me, could you try it, too?

[mingcenwei]

@fendor Thank you! I have just tried the commands. However, the problem persists.

EDIT: If I open app/Main.hs in VS Code, in a while the bottom of the window will show Initializing Stack project, and then it will disappear and the error message will appear

[fendor]

Can you show the log? E.g. press
and then select "output" and the haskell-ide-engine tab. Maybe there is something the logs?
If you are running into #1495, you need to put the appropriate ghc version on the path for now.

[mingcenwei]

I removed all the symlinks for GHC 8.8.1 from $PATH and substituted them with symlinks for GHC 8.6.5. However, the problem is still there. The following are the logs.

OK, can you try adding a file hie.yaml in the top-level directory with the contents:

cradle:
  stack:

Does that work?

[mingcenwei]

@fendor Yes, now it works well! Thank you very much!

[fendor]

Glad to hear that but you are not off-the-hook yet! We still have to find out why it doesnt work out-of-the-box.

To extend your configuration, see https://github.com/haskell/haskell-ide-engine#project-configuration
This is useful if you have a more complicated project with multiple executables.

I appreciate your efforts! I will continue watching this issue. Please let me know if there's anything that I can help with.
