Expected Behaviour

The test suite should pass consistently.

Actual Behaviour

One time when running the tests, I saw this failure. However, I haven't seen it since.

bin/lua-language-server: attempt to yield from outside a coroutine
stack traceback:

The test failed in Alpine's build system CI and the full output is here: https://gitlab.alpinelinux.org/xordspar0/aports/-/jobs/1554206

Reproduction steps

1. git clone --recursive https://github.com/LuaLS/lua-language-server.git
2. cd lua-language-server
3. ninja -C 3rd/luamake -f compile/ninja/linux.ninja
4. 3rd/luamake/luamake all
5. 3rd/luamake/luamake unit-test
6. Rarely see the above failure.

Additional Notes

lua-language-server version: 3.11.1

No response

まず、記載されている build コマンドと unit-test コマンドを実行し、その後、報告された coroutine.yield のスタック付近にある script/await.lua、workspace/workspace.lua、test/full/self.lua を調べます。Alpine CI のログとテストの繰り返し実行を使って、断続的な失敗を調査します。unit-test スイートが coroutine の外部で yield することなく、一貫して成功すれば完了です。
