Can we just use js-test-pre.js, which also defines gc()? I'm not quite sure if this script doesn't have any side effects when included though.

Use gc() in js-test-pre.js instead.

I changed the code to use js-test-pre.js and reran all the tests locally and they seem to pass. Lets see what the EWS bots say. The mechanism for triggering GC when GCController is not available is different in the js-test-pre.js implementation, but I'm not sure how much that matters.

Good refactoring. GC behavior is a bit unpredictable (e.g. 10000 and 100000 can result in different behavior) and thus it's important to maintain the code in one place.

Actually I've observed a couple of cases where manually written gc() didn't trigger a major GC of V8 because the number of object instantiation was not enough.

r=me too, but I have comments that need to be addressed.

We should not have these files in http/tests/resources. Someone was confused when adding them.

Please use "/js-test-resources/js-test-pre.js". This path is mapped to fast/js/resources, so we avoid code duplication.

It would be helpful to remove the copies in http/tests/resources.

I've changed includes to /js-test-resources/js-test-pre.js, but I think removing the duplicate file and updating the other tests should be in a different patch since it is unrelated to the goal of this bug.

The title of this bug is "Remove GC code duplication in http/tests LayoutTests", so updating other tests is part of that task as stated. It's perfectly fine to do it in one patch or in multiple patches, whichever is more practical.
