Scans all yaml files with cfn-lint at startup. #198

Open b3cft opened 3 years ago

b3cft commented 3 years ago

Issue Type: Bug

I have a couple of hundred cloudformation templates and serverless templates in my default workspace.

Every time I start or reload vscode it scans all the yaml files with cfn-lint.

It pushes to load average up to approx 200, until the WSL stops responding and disconnects. Then reconnecting it does it again. Rinse, repeat.

I've had to start running

pkill -f cfn-lint

multiple times in a terminal session when vscode or my machine reloads to keep it under control.

Is there a way to add a setting, to only lint files on open, rather than scan the whole workspace on load?

The default configuration, if the VS Code docs are correct, is that it will only scan on files being open.

Do you have a .cfnlintrc file?

b3cft commented 3 years ago

No, I don't have .cfnlintrc file in the workspace or my home dir.

I am running into this issue as well and dont have a cfnlintrc either. Is there some way to only limit the behavior of this plugin to only evaluate the open file?

gmergulhao commented 1 year ago

also running into this issue, which causes 100% ram utilization since cfn-lint runs for 100+ templates. same behaviour with pip installed cfn-lint versions 0.50, 0.60, 0.63, 0.65 running python 3.10 x64

I may have to add some debugging output to get more details but can you provide me the abbreviated Output from the plugin? We should see the execution for every file that was opened or saved. We should only see executions for the files that are open.
