`Could not load module`/`Cannot satisfy -package` error for exe/test/bench component whose main lib doesn't build or was not built

[runeksvendsen]

Overview

Oftentimes I will change code in the library component of a project, and then fix the test suite by following compiler errors. However, this doesn't work for me with HLS, as the test suite not compiling causes VSCode to report the following type of errors for imports in the test suite that are dependencies of the test suite:

Could not load module ‘<test dependency module>’
It is a member of the hidden package ‘<test dependency>’.
You can run ‘:set -package <test dependency>’ to expose it.
(Note: this unloads all the modules in the current scope.)

Reproducing

This should be reproducible with the following steps:

1. Run the following commands to clone and build the example repo (the last step results in a compilation error):

git clone https://github.com/runeksvendsen/bellman-ford.git
git checkout 781835aa000ad40f6c54f2c7426e9378ff6905e4
stack build
stack test

2. (Now I would like help from VSCode to fix the test suite error) open the project in VSCode and browse to e.g. the file test/Spec.hs

Result

Test dependency module imports report an error, e.g.:

Could not load module ‘Test.Tasty’
It is a member of the hidden package ‘tasty-1.2.3’.
You can run ‘:set -package tasty’ to expose it.
(Note: this unloads all the modules in the current scope.)

Expected

VSCode highlights the errors that GHC prints in the stack test build step.

Does it emit the same error even on your master branch? More specifically, when you provide a hie.yaml file.

[runeksvendsen]

With the hie.yaml file from master, instead of the "Could not load module"-error for test dependency imports, the following error occurs (reported for the first line of the source file):

Hm... the log looks innocent...
Have you built your library before opening the file? Being without build process causes such errors sometimes.

[runeksvendsen]

Yes. I've run stack build and stack test before opening the project in VSCode.

Are these log lines not an indication of something awry?

No, it is a spurious error: #181

I see something that is weird:

We see this line very often, but it should only occur once per component.
Could you run the server in debug mode? You can do haskell-language-server --debug test/ and it should try to load all modules in the test directory.
Personally, I am interested in lines such as: Session loading result: as they tell us whether loading actually succeeded.

[runeksvendsen]

I see something that is weird:
[...]
We see this line very often, but it should only occur once per component.

Yes. When there is no hie.yaml file present and I open VSCode then in the project file explorer I can see each source file in test/ slowly turn red, one at a time. So it looks like this log line appears for each source file in the test/ directory.

Could you run the server in debug mode? You can do haskell-language-server --debug test/ and it should try to load all modules in the test directory.

With hie.yaml present:

Without hie.yaml we see this:

[INFO] Making new HscEnv[main,main,main,main,main,main,main,main]

which is definitely a bug and hints that each file is put into its own component.
What happens on stack repl? And what happens when you do stack repl bellman-ford:test:bellman-ford-test?

I still don't see the debug message I am interested in...

[runeksvendsen]

stack repl loads the library without errors:

Loading only the test suite in the REPL emits the error cannot satisfy -package bellman-ford-0.1.0.0 that HLS outputs with hie.yaml file present:

And loading both the library and test suite outputs the error that I'm interested in (in the file test/Digraph/Spec.hs). This is the same error that GHC outputs when I run stack test in a terminal:

That this command: $ stack repl bellman-ford:test:bellman-ford-test does not work is a stack bug in my opinion.
It should work, and it is the reason the explicit hie.yaml fails.

What is your stack version? We should probably report this issue/regression to upstream.

[Ailrun]

After removing all errors and successfully building the test once, it looks like it works fine...

[runeksvendsen]

All the above was run using stack 2.3.1 (Git revision de2a7b694f07de7e6cf17f8c92338c16286b2878).

Upgrading to 2.3.3 the output of stack repl bellman-ford:test:bellman-ford-test improves, in that it prints the error I'm looking for. However it still ends up failing with cannot satisfy -package bellman-ford-0.1.0.0:

After removing all errors and successfully building the test once, it looks like it works fine...

Yes. In my experience the error appears when I change something in the library, and then open a source file from the test suite (which now fails to build). Then HLS fails with this error (missing either all test dependencies or the library dependency). However, fixing all errors in the test source files, and introducing a new error in one of the tests HLS works fine. I haven't figured out the exact conditions that cause this error, but I know it happens after refactoring the library and then navigating to a file in the test suite (which now fails to build).
