Why is the garbage collection being disabled?

Hi,

I noticed the checkout action is disabling the garbage collection of the local git repo. Since the .git folders of our local repos on our self-hosted runners are starting to get bigger, I was wondering why it is being disabled and if this is something that should be optional?

checkout/src/git-source-provider.ts

Line 92 in afe4af0

if (!(await git.tryDisableAutomaticGarbageCollection())) {

Thanks for the feedback.

Same problem where with self hosted runners.

I guess this is not an issue for the GH runners because they are using short-lived VMs. One workaround I can think of would be to use a post job script 1 and do something like

git config gc.auto 1024
git config gc.packLimit 10
git gc --auto

in it. But that is also a bit wasteful although this should be fast in the common case that no garbage collection is required.

At 1 is an example of a monthly job which runs on all self-hosted runners. The trick is to give a unique label to each runner and then apply a matrix onto it.
