Language server logs not showing up in remote development
Summary
It seems like language server support on remote development is poor. I am frequently seeing errors like (remote server) oneshot canceled, do not see any feedback in the notifications on whether the language server is running, when looking at debug logs for the language server, I see multiple instances of the language server running.
I also don't see any of the status messages in the bottom left on remote development (i.e "Initializing Workspace", "Importing root project", "Refreshing Workspace" etc.) whereas I see them when running locally.
Description
To reproduce, open a Java file using remote development while having the https://github.com/zed-extensions/java extension installed.
Expected Behavior: Logs when I run locally:

Zed's page says it's coming soon. Has support for extension been released?
@josecanciani, yes we have extensions support. You can read about them at https://zed.dev/docs/extensions, I'm not sure where you got that screenshot of the site, it seems to be outdated
@Alaska47 are the Language servers working as intended? From your description it sounds like just the logs aren't going through, but the language servers themselves are working

Main Page -> Remote Development https://zed.dev/remote-development
There you can see the "extensions support coming soon".
I'll give it another try when I'm a bit free again. Any tips on how I could debug this to know if it's running? I tried using the PHP extension (which uses phpintelliphense if I remember correctly).
You can see the running language servers in the dropdown in the top left of the pane opened by dev: open language server logs

Thanks, I could open the log, but I don't find anything related to php. I have the extension installed, but I only see a tailwind lsp:
Should I be getting something else?
That means the PHP language server is not running, there is likely an error message in the zed logs (zed: open log), if you could find it and share it I can help you figure out what's going wrong if needed
I have zero LSP and server logs for anything (including r-a) for any ssh remote project. Steps to repro are trivial: open any buffer, open lsp logs.
Seems like the issue is similar to https://github.com/zed-industries/zed/issues/27328 where the replies say:
I see, seems we're just not sending the server logs from the remote to the client at all.
I can also verify the same behavior for clangd, it is definitely running on the remote machine but no logs show up on the client.
