ansible
Fork bomb getting `ansible-lint --version`
Type: Bug
I have an ansible playbook repo. With this extension installed, when loading an ansible file in that repo, I get a fork bomb of ansible-lint --version commands. It can get to the point of consuming 100% of my CPU and RAM.
Extension version: 2.0.58 VS Code version: Code 1.77.3 (704ed70d4fd1c6bd6342c436f1ede30d1cff4710, 2023-04-12T09:16:52.732Z) OS version: Linux x64 6.2.13-300.fc38.x86_64 Modes: Sandboxed: No

Can also confirm this is happening to me now. Nothing on my system has changed (minus updating vscode and extensions)
Noticed the same when doing a search and replace over a couple of hundred files in VSC. Without the plugin, everything works fine, but having this one activated ansible-lint also seems to scan every file VSC takes on action in the background.
- Are you experimenting this with a single folder/workspace open in vscode or multiple?
- Is the number or processes started equal to the number of open tabs or modified files in case of search/replace action?
- Try to reproduce the bug with like 3 tabs, and see if you get 3 processes.
If we have confirmation on this, we might be able to chain the operations and avoid running them in parallel.
Question 1 is quite important because for multi-workspace case, we might not be able to do that as different instances of the language server will be running.

Single.

More or less I can see now one process per tab, which is different to the fork bomb I was seeing before.
However now I see one process consuming 100% CPU for a very long time:
/usr/share/code/code /var/home/yajo/.vscode/extensions/redhat.ansible-2.13.148/out/server/src/server.js --node-ipc --clientProcessId=40820
Notice that ansible-lint usually lints the whole directory at once. At least, when used with pre-commit, it should not run per file, but per workdir.
