DM writes out its images in a hierarchy that's a little different than GM, so this can't read GM's output. But it can read its own, written with -w. Example usage: $ out/Release/dm -w /tmp/baseline $ out/Release/dm -r /tmp/baseline -w /tmp/new (and optionally) $ mkdir /tmp/diff; out/Release/skdiff /tmp/baseline /tmp/new /tmp/diff GM's IndividualImageExpectationsSource and Expectations are a little too eager about decoding and hashing the expected images, so I took the opportunity to add DM::Expectations that mostly replaces skiagm::ExpectationsSource and skiagm::Expectations in DM. It mainly exists to move the image decoding and comparison off the main thread, which would otherwise be a major speed bottleneck. I tried to use skiagm code where possible. One notable place where I differed is in this new feature. When -r is a directory of images, DM does no hashing. It considerably faster to read the expected file into an SkBitmap and do a byte-for-byte comparison than to hash the two bitmaps and check those. The example usage above isn't quite working 100% yet. Expectations on some GMs fail, even with no binary change. I haven't pinned down whether this is due to - a bug in DM - flaky GMs - unthreadsafe GMs - flaky image decoding - unthreadsafe image decoding - something else but I intend to. Leon, Derek and I have suspected PNG decoding isn't threadsafe, but are as yet unable to prove it. I also seem to be able to cause malloc to fail on my laptop if I run too many configs at once, though I never seem to be using more than ~1G of RAM. Will track that down too.
