Hi All,
I am working on moving JSC EWS queues from old EWS to new EWS. I am trying to clearly understand various JSC EWS queues. I have few questions:
1) What does 'jsc-only' port represent? From https://trac.webkit.org/browser/ webkit/trunk/Tools/Scripts/webkitpy/common/config/ews.json#L45 it seems like Apple JSC EWS uses 'mac' port, while linux jsc EWSes use 'jsc-only' port. Is jsc-only port specific to linux? Is there a corresponding jsc port for mac?
2) Is there any difference between the three linux JSC EWSes (JSC i386, JSC MIPS32el, JSC Armv7) apart from the architecture and few queues running/ skipping tests?
I think the main difference is indeed the different architecture. There is also the fact that the JSC i386 EWS runs the tests natively, but the mips and armv7 EWSes cross-compile and run the tests on a set of remote devices.
3) Where is the architecture for various linux JSC EWS queues configured in the old EWS code (e.g.: I don't see the architecture being added in https:// trac.webkit.org/changeset/237001/webkit)? Is the queue configuration for various JSC EWS queues same, and the device connected to the queue actually decides the architecture?
I guess it's not defined anywhere indeed. The scripts that start the queues for the arm and mips EWSes define a bunch of env variables to point to the cross-compiler and also add a few options in JSCTESTS_OPTIONS, such as a --remote-config-file and --memory-limited. I can share these scripts with you if you need more details. Hope this helps. Cheers, Guij
