Has GC_INTERVAL gone missing?

Expected behaviour

A config parameter GC_INTERVAL is listed in Thumbor’s documentation here. It was added from this PR back in 2017. I’ve been attempting to use this while troubleshooting high memory usage on our Thumbor pods.

Actual behaviour

But the code in thumbor/server.py to implement timed garbage collection has since disappeared, and grepping the codebase for any use of GC_INTERVAL returns no matches. Is GC_INTERVAL still supported?

I can’t speak for everyone but my use case is deploying it to a Kubernetes cluster alongside the rest of our application stack, and I imagine that’ll be a fairly common one. Best practice is to give pods a fixed memory limit so while we aren’t very resource-constrained we do need predictable usage.

As @kkopachev noted the usage for us has stabilised around 1GB per Thumbor instance. That’s a lot higher than before but we can live with it. I had hoped the GC_INTERVAL setting would help us reduce it by triggering garbage collection differently.

Given GC_INTERVAL no longer does anything I think a simple solution would be to remove it from the documentation. Lower memory usage is always welcome though!
