Not starting on OTP26

[lukaszsamson]

There are several issues that make ElixirLS fail on OTP26. Some of them are already addressed on https://github.com/elixir-lsp/elixir-ls/tree/otp26 but some will need to wait for fixes upstream

• [x] dialyzer changed some internal APIs we depend on
• [x] changes in stdio interception
• [x] calling self now crashes io
• [x] OTP26 has critical bugs in stdio, e.g. https://github.com/erlang/otp/issues/7132 https://github.com/erlang/otp/issues/7230
• [x] stdio hangs on Windows https://github.com/erlang/otp/issues/7459

Hi, I just wanted to add that it does not work with the released version of Erlang 26.0. I am running elixir-ls in LunarVim and get this in the LspLog

Even with the OTP26 branch with master merged in things are working much, much better ;)

It crashes on first utf character in client request

It crashes on first utf character in client request

I see one crash, and then it seems to work fine after that.. (where previously it would just crash repeatedly.) I merged master into a local copy of this branch and recompiled. I'm using Elixir 1.15 and OTP 26.0.1

Not saying it's fixed. But it's actually usable right now for me...

[dvic]

FYI, the last open bug in OTP 26 has just been closed 🎉

[lukaszsamson]

Now we need an OTP release OTP-26.0.2 with the fix and find a way how to pass -standard_io_encoding latin1 to launch scripts

[garazdawi]

It would be great if you could test the latest maint before we release 26.0.2 and see if there are any more issues so that we can fix them as well. The plan is to release 26.0.2 early next week.

Just compiled and installed maint and getting the following error:

This is with what sounds to a the fix: https://github.com/erlang/otp/commit/bf1916dbbecb74c8315c83ffabf412ee36aef6d4

with the flag set as --erl "-kernel standard_io_encoding latin1" ... ( not sure if this is right ).

I also tested the credo-language-server over stdio which is working as expected.

Wonder how or where you can set the path for the Elixir source… but I think it's our last problem here ;)

[lukaszsamson]

Instead of posting the same crash log again and again what would actually help here would be testing the new flag added on OTP master.

[dmilith]

Nope. With the Otp master from today (2023-06-25 18:45 CEST):

Unfortunately, the process crashes very similar fashion as before.

[lukaszsamson]

Are you running with --erl "-kernel standard_io_encoding latin1"? Also OTP26 branch has other changes that may be needed

[lukaszsamson]

I added -kernel standard_io_encoding latin1 to launch scripts and it seems to be working OK with maint OTP branch. ElixirLS changes in https://github.com/elixir-lsp/elixir-ls/tree/otp26 branch. I'm going to run some more tests and cleanup the patch before it's ready for merging

[lukaszsamson]

Fixed in https://github.com/elixir-lsp/elixir-ls/pull/923

[axelson]

@lukaszsamson congratulations on getting this fixed! :tada:

Quick question, are there specific versions of OTP 26 that still aren't supported after this change? i.e. is OTP 26.0.1 required? If so then we may want to add that info to the README or ideally add a warning if we detect that we're running on an unsupported version of OTP (although maybe that's not feasible).

[lukaszsamson]

The OTP fix is attached to 26.0.2 milestone. I'll update the readme when it's out

[Fudoshiki]

Release a new version of the vs code extension?

[wkirschbaum]

@lukaszsamson thank you for the effort ❤️. I can confirm it is working, so I must have done the flag wrong.

[moogle19]

@lukaszsamson OTP 26.0.2 just released! 🙂

[nallwhy]

I still have the problem with OTP 26.0.2, Elixir 1.15.0-otp-26.

Maybe VSCode installs v0.15.0 yet, not v0.15.1.

There were no ElixirLS release yet

I'm running into the same error like @nallwhy on Fedora Linux 37 with VSCodium 1.79.2. Everything works with Erlang 25.3.2 and Elixir 1.14.5-otp-25. When I switch to Erlang 26.0.2 and Elixir 1.15.2-otp-26 this happens:

[lukaszsamson]

@adonig Please read release notes carefully. OTP 26 is supported since 0.15.1 and you are running 0.15.0

Installing ElixirLS release v0.15.0

[adonig]

@lukaszsamson I'm not intentionally running 0.15.0. It looks like I'm running 0.15.1 and it's installing 0.15.0, see here:

Running /home/asd/.vscode-oss/extensions/elixir-lsp.elixir-ls-0.15.1-universal/elixir-ls-release/launch.sh

I believe it's the same problem@nallwhy has. He's also running 0.15.1 and then it's installing 0.15.0 for some reason.

EDIT: So I went into the folder /home/asd/.vscode-oss/extensions/elixir-lsp.elixir-ls-0.15.1-universal/elixir-ls-release/ and read the source code of installer.exs and it looks like it gets the version from the VERSION file in the same folder and there the version 0.15.0 is hardcoded:

[asd@fwk elixir-lsp.elixir-ls-0.15.1-universal]$ cat elixir-ls-release/VERSION 
0.15.0

EDIT2: I changed the contents of the VERSION file manually to 0.15.1 and now everything works:

I'm not sure why there is the old version in that file. I believe I even deleted the whole /home/asd/.vscode-oss/extensions/elixir-lsp.elixir-ls-0.15.1-universal directory and did a clean reinstall of the ElixirLS extension like a week ago because I just couldn't get OTP26 working.

@adonig the release asset https://github.com/elixir-lsp/elixir-ls/releases/download/v0.15.1/elixir-ls-v0.15.1.zip includes a correct 0.15.1 version manifest

[lukaszsamson]

If you only modify the version you will end up using launch scripts from some other release which may be incomptatible

[adonig]

@lukaszsamson I uninstalled ElixirLS in VSCodium but it didn't remove the folder elixir-lsp.elixir-ls-0.15.1-universal in ~/.vscode-oss/extensions/. So I deleted the folder. Then I installed ElixirLS in VSCodium again and I immediately get the error again. When I check the VERSION file it contains the old version again:

[asd@fwk ~]$ cat $HOME/.vscode-oss/extensions/elixir-lsp.elixir-ls-0.15.1-universal/elixir-ls-release/VERSION 
0.15.0

I don't know whether this is because I'm using VSCodium and they get their release assets from another place or whether there is some kind of extension release asset cache in VSCode that prevents it from downloading the new release asset.

[lukaszsamson]

You are installing the wrong version once again. VSCode plugin versioning is independent from elixirLS versioning. You need 0.15.2 https://github.com/elixir-lsp/vscode-elixir-ls/blob/master/CHANGELOG.md#v0152-29-june-2023

[adonig]

It looks like the newest version available is 0.15.1:

asd@fwk ~]$ codium --install-extension elixir-lsp.elixir-ls

So I probably have to install it like described in the installation section of the README because it didn't get released yet?

Sorry for the turmoil but because of the vscode extension version 0.15.1 I thought that I'm installing ElixirLS 0.15.1 all the time.

Thank you @lukaszsamson for your patience. Since these issues are not related to ElixirLS itself, they could be moved to the vscode-elixir-ls repository, if there is indeed an issue?

[garazdawi]

I've done a fix for the Windows issue in https://github.com/erlang/otp/pull/7473. Would be great if you could test that both Unix and Windows still work as they should for ElixirLS.

[garazdawi]

Fix merged, but I'll hold of making a patch until I get confirmation here (or in erlang/otp#7473) that the fix solves the issue and that no new ones have popped up.

Maybe this should be pinned to the top of Open Issues, and maybe the title should be renamed to "elixlir-ls on OTP26 does not work in VSCode" or "Don't upgrade to OTP26 with VSCode". I'm new to Elixir (so I haven't upgraded from a previous version), and it took me some time to:

• even discover that elixir-ls wasn't running
• find out that the cause was OTP

i.e. for someone new to Elixir, being a bit more explicit about the problem would be helpful

[lukaszsamson]

@dr1ver1 It is already pinned since OTP 26 rc.3 release and mentioned both in release notes and README. There were at least ten threads on the forum and messages on slack. It does not stop people from running on incompatible versions and raising issues...

[dr1ver1]

ok. I was looking through issues at https://github.com/elixir-lsp/vscode-elixir-ls/issues I guess I was looking in the wrong place

[axelson]

@dr1ver1 I've added a pinned issue to that repo for additional visibility: https://github.com/elixir-lsp/vscode-elixir-ls/issues/365

[jschaeff]

Hello, I'm not sure to help here, but I wanted to report that elixir-ls 0.16 still fails on Archlinux with OTP26. By following this issue, I expected that the remaining problem was only for windows and the others were already fixed in 1.16 release. Is there a branch of elixir-ls that works on linux with OTP 26 ?

This is my error message when running in emacs with lsp-mode:

Process elixir-ls stderr finished
Runtime terminating during boot ({badarg,[{io,put_chars,[standard_error,[_]],[{_},{_},{_}]},{Elixir.Kernel.CLI,exec_fun,2,[{_},{_}]},{Elixir.Kernel.CLI,run,1,[{_},{_}]},{elixir,start_cli,0,[{_},{_}]},{init,start_em,1,[]},{init,do_boot,3,[]}]})

[lukaszsamson]

@jschaeff Please make sure you run OTP >= 26.0.2

[jschaeff]

Yes it's OTP 26.0.2

[lukaszsamson]

Please post more logs. Can you create a dockerfile that reproduces it?

[lobo-tuerto]

Latest version of elixir-ls (v0.16.0) runs without problems on Linux with the following versions:

• elixir: 1.15.5-otp-26
• erlang: 26.0.2

[lukaszsamson]

OTP 26.1 is out with the fix for https://github.com/erlang/otp/issues/7459, I'll test it out later

[jschaeff]

Please post more logs. Can you create a dockerfile that reproduces it?

It's hard to make a docker container that mimic's the dialog between emacs lsp-mode and elixir-ls, but it lead me to another path: by switching from lsp-mode to eglot, I got it working. This is a bit weird ... but then maybe it's an lsp-mode bug ?

Sidenote: It's also a bit weird that archlinux is so much behind in the elixir package (1.15.0)

[Hermanverschooten]

I have just tested erlang 26.1/elixir 1.15.4 with 0.16 in one of my projects, it works but some vim restarts were necessary. I removed both my _build and .elixir_ls upfront, but that's something I always do when switching versions. Oh and I am using rtx not asdf, on Mac OS Ventura 13.5.2 M2.

[garazdawi]

OTP 26.1 is out with the fix for https://github.com/erlang/otp/issues/7459, I'll test it out later

I'm curious, why wait for the release to test it? If you had tested my PR and confirmed that it fixed the problem I would have released a patch with this fix 2 months ago.

[lukaszsamson]

I can confirm that elixir-ls 0.16 with OTP 26.1 is working on windows

I'm curious, why wait for the release to test it? If you had tested my PR and confirmed that it fixed the problem I would have released a patch with this fix 2 months ago.

Let's put it like this: building OTP on windows isn't the easiest of tasks

Each PR opened towards our repository creates an .exe installer that can be used for testing. There is link to it in the auto-generated comment: https://github.com/erlang/otp/pull/7473#issuecomment-1620327191

[lukaszsamson]

I'm closing the issue as now all main OSes are working with OTP 26
