Not done yet. I want to respin once more before it hits next. I've picked up a number of test related changes from Clemens Buchacher and Tay Ray Chuan, plus some suggestions from the latter were fixed up in the WebDAV code. John "warthog9" Hawley and I were spending some time yesterday to try to figure out why smart HTTP serving off kernel.org was giving me only 300 KiB/sec during clone, but git-daemon was giving me 12 MiB/sec for the same server and repository. Peff noticed the TCP windows for smart HTTP were ~16 KiB in size, but with git-daemon were ~200 KiB on size. John and I are pretty sure this is the throughput problem, but we haven't found why the window is so much smaller under smart HTTP. We also need proper tests for smart HTTP. I haven't had time to write tests yet, and the ones that were proposed for t5540-http-push aren't suitable because you have to run the test suite twice in order to test both WebDAV and smart HTTP push for the same build. -- Shawn.
