It's +capable of comparing the sizes of ChromeOS images, and the size of Chrome's +debuginfo. An example of this is: + +``` +$ ./fetch_cq_size_diff.py --image gs \ + gs://chromeos-image-archive/asurada-release/R122-15712.0.0/image.zip + gs://chromeos-image-archive/asurada-cq/R122-15712.0.0-92036-8761629109681962289/image.zip +``` + +For convenience, this script can also figure out what to compare from a CL, like +so: + +``` +$ ./fetch_cq_size_diff.py --image cl \ + https://chromium-review.googlesource.com/c/chromiumos/overlays/board-overlays/+/5126116/3 +``` + +In the above case, this script will find a completed CQ build associated with +PatchSet 3 of the given CL, and compare the `image.zip` generated by said build +with the image.zip generated by a release builder for the same board. CQ +attempts don't have to be entirely green for this; as long as there're a few +green boards to pick from, this script should be able to make a comparison. |
