Segfault on empty YESOD project #230

makarenya · 2020-07-23T21:51:37Z

In visual studio code i got The Haskell (yolo) server crashed 5 times in the last 3 minutes. The server will not be restarted on Yesod project, just created by:
stack new yolo yesodweb/sqlite
In the project root command:
/Users/username/Library/Application\ Support/Code/User/globalStorage/alanz.vscode-hie-server/haskell-language-server-0.2.1-darwin-8.8.3
make a lot output, ends with

Ok, I try to use haskell-ide-engine instead of haskell-language-server with same segserv result.
BUT! i insert some debug output in the haskell-ide-engine, and got something:
segserv happends on this line in haskell ide engine, and i think, that in this porject is same.
https://github.com/haskell/haskell-ide-engine/blob/master/hie-plugin-api/Haskell/Ide/Engine/ModuleCache.hs#L256

The text was updated successfully, but these errors were encountered:

You can get same repo, just typing stack new yolo yesodweb/sqlite, ghc 8.8.3
System: macOs Catalina. And it's not new bug for me, it reproduced on previous mac os on ghc 8.6.5

jneira · 2020-07-24T09:14:01Z

Hi, are you using a explicit hie.yaml? if that is the case please attach it. Otherwise try to open the project creating the explicit hie.yaml, following the readme: https://github.com/haskell/haskell-language-server#project-configuration .
The ide tries to load your files without hie.yaml calling stack repl path/to/file underneath. What is the output if you executes stack repl app/devel.hs?
Also there is an error about hspec not present, it is closely related with #176, and the workaround is to install the executable globally.

makarenya · 2020-07-24T09:34:51Z

Before you last message i use pretty simple hie.yaml:

cradle:
  stack

But, after reading it, i change hie.yaml to

cradle:
  stack:
    component: "haskell-language-server:lib"

And got new error:

> Error parsing targets: Unknown local package: haskell-language-server

I think, that i must do some additional installation steps to solve it...
But i'm sure after fixing this issue, i will get the segfault back.
Next:
stack repl /app/devel.hs output:

Warning: Couldn't find a component for file target /Users/username/projects/yolo/app/devel.hs. This means that the correct ghc options might not be used.
         Attempting to load the file anyway.
Configuring GHCi with the following packages:

Ok, one module loaded.
Loaded GHCi configuration from /private/var/folders/9y/h9dg4bhn3759h7ybs9djb27j7t15nw/T/haskell-stack-ghci/aafecffd/ghci-script

And I want to reiterate that this is not an exception, but a segfault.

jneira · 2020-07-24T14:21:57Z

But i'm sure after fixing this issue, i will get the segfault back.

Yeah it is probable, still they could be related (f.e. one could cause the other).
Even if the segfault is not related you will need to fix the load of the project anyways 😉 .

The hie.yaml should describe your project components (libs, exes, tests), not the haskell-language-server ones so it would look:

PS D:\dev\ws\haskell\issues\yolo> cat .\hie.yaml
cradle:
  stack:
    - path: "./src"
      component: "yolo:lib"

    - path: "./app/main.hs"
      component: "yolo:exe:yolo"

    - path: "./app/DevelMain.hs"
      component: "yolo:exe:yolo"

    - path: "./app/Paths_yolo.hs"
      component: "yolo:exe:yolo"

    - path: "./test"
      component: "yolo:test:yolo-test"

I've used the utility gen-hieto generate the hie.yaml, installed with stack install implicit-hie.

Without the hie yaml i got 13 files worked, 7 files failed (log)

With that hie.yaml, 19 files worked, 1 file failed (log). The module that fails is ./app/devel.hs.

makarenya · 2020-07-24T14:30:12Z

Thank you for support, gen-hie works fine. So, segmentation fault come back.

Jumm, ok, when the language server crashes, could you see the same error in the hls output? please, attach that log just in case it could help.
In my windows 10 i am able to load the project (screenshot to show where the output can be found):

The hie.yaml i am using now is this one:

cradle:
  multi:
    - path: "./app/devel.hs"
      config: { cradle: { none:  } }

    - path: "./"
      config:
        cradle:
          stack:
            - path: "./src"
              component: "yolo:lib"

            - path: "./app"
              component: "yolo:exe:yolo"

            - path: "./test"
              component: "yolo:test:yolo-test"

And yes, it's only os x problem, i use haskell-ide-engine with vim on ubuntu without any problems.
Half a year ago i find workaround: using haskell-ide-engine from nix build. I don't know why, but it work without any problems. It was good a half year ago. But all-hies project stops to update... And workaround not working for 8.8.3 and newer

jneira · 2020-07-24T20:21:21Z

And the executable was automatic downloaded by the extension so it comes from the release of this repo.
Maybe @bubba can help, given the tip about the nix build you mentioned.

makarenya · 2020-07-25T11:27:11Z

Can I somehow help identify the problem? For example, I can try to localize the source of the segfault. In the case of haskell-ide-engine, I have already done this, I wrote it off earlier.
And for haskell-language-server, this is one of 2 places (errors occur sometimes in one, sometimes in another)

You can get same repo, just typing stack new yolo yesodweb/sqlite, ghc 8.8.3
System: macOs Catalina. And it's not new bug for me, it reproduced on previous mac os on ghc 8.6.5

One thing to note is that stack new won't necessarily give the same results over time:

The underlying template may change
stack new will choose a Stackage version for you, that also might change over time

So, probably best to create a new Github repo with the exact configuration you have to help people reproduce

Just double checked here, this happens on HLS built from source as well, not just with the static binaries

@bubba - I got the same thing with both hls and ghcide. In my case, I was using the path library and the mkAbsFile family of template haskell functions. Once I removed those, segmentation fault disappears in both applications. I suspect that #230 and #277 are duplicates.

Hi. Sorry for the long delay. My repo: https://github.com/makarenya/yolo
Over the past time, I managed:

Check this repo on mac mini with macOS high sierra - it worked without issue.
Change my laptop to a new one, but of the same model, and also with a Catalina - the error persists.
So I assume that there is a certain connection with a specific OS.
Possibly with a certain hardware on my MacBook Pro (15-inch, 2017)

makarenya · 2020-08-27T10:59:06Z

UP. I tried to reproduce error on MacBook Pro (Late 2013) with macOS Catalina. And it reproduced.
So. macOS Catalina. and only it.

navilan · 2020-08-27T12:29:54Z

I'm on Mojave - so I guess whatever the issue is, ~~it got fixed on high sierra~~ it got created in mojave :)

makarenya · 2020-08-27T12:33:04Z

Catalina is the latest version of macOS. Fixed in High Sierra but reproducible on Catalina? Strange ...

navilan · 2020-08-27T16:28:06Z

Yeah, I got my Mac OS X version chronology wrong :)

vikrem · 2020-09-09T03:20:52Z

Also running into this, using MacOS 10.14.6 (Mojave). Are there any recent updates on this?

+1

Fails on version 0.5 and 0.6 and master of haskell-language-server. OSX Darwin difference.local 18.7.0 Darwin Kernel Version 18.7.0: Mon Aug 31 20:53:32 PDT 2020; root:xnu-4903.278.44~1/RELEASE_X86_64 x86_64. Specific project only, works on others.

Likely duplicate of #469 which is a bug upstream in GHC. There are more details in that issue, including a workaround.

dcastro · 2021-10-21T09:43:07Z

Since everyone else having this problem seems to be on macOS, I'm just leaving a comment to say I've also had this problem on Ubuntu 20.04.3 LTS.

As pointed out in other issues, running cabal configure --enable-executable-dynamic and compiling from source fixed the issue for me.
