Adding async-request-handlers for lsp-json

[kiennq]

Since json language server requests emacs to provide file/remote resource content that may take time to retrieve, we need to make the request response being able to not block typing via async callback,

This is per discussion in #1073

Looks good! You may fix lsp-json.el header as well.

I had some troubles when testing on clean machine with emacs 27.

1. The automatic install does not work on linux systems since it requires super user privileges. I suggest removing automatic installation until we make it work for all systems.
2. The lists must be vectors because emacs 27 json serialization supports only vectors.

Are you talking about lsp-json--schema-associations? Also I wonder where can you get the emacs-snapshot version that support json serialization?
I'm on Ubuntu (via WSL) and install emacs with this PPA https://launchpad.net/~ubuntu-elisp/+archive/ubuntu/ppa

Oh, it works great on Windows though.
In my Ubuntu, once I set npm config set prefix '~/.npm-global', then install npm i -g will not require sudo anymore.
I'm not sure if there's anyone really install some packages for everyone on their machines.
For now I will scoop down the automatic installation to Windows, is that fine?

I don't know - I am compiling it from source - Another option is to use lsp-docker, which has emacs 27.

lsp-json--schema-associations
lsp-json--extra-init-params

I fixed these locally but I am unable to get completion working.

In general, I prefer having #506 in before working on any automatic installations because it makes the task harder(e. g. whoever starts working on it will have to fix all automatic installations that are implemented). If you insist keep it for windows.

Can you post the locally fix here? I don't have emacs27 with native json now, so it would be better to reuse your fix.

The latest vscode-json-languageserver has problem, you may need to install the version before it.

It works fine after this commit.

Can you document that?

Fixed!!!

Thank you!

As a side note, when you mark a server with :multi-root t lsp-mode will run only one instance of that server but I am not sure whether it could cause issues if the server does not support workspace folders.

Oh, I didn't know about this. Certainly lsp-json could be benefit from this
