Inspired by everybody's awesome work getting the 3D extension live, I spent some time yesterday making some tweaks, including working with Hashar to get continuous integration testing working for the 3d2png tool. :) Review on the patches would be welcome! 3d2png: * https://gerrit.wikimedia.org/r/#/c/413182/ - fix for test on node 7+ * https://gerrit.wikimedia.org/r/#/c/413183/ - fix for test loading files before they're completely written * https://gerrit.wikimedia.org/r/#/c/413184/ - update reference rendering to match current code * https://gerrit.wikimedia.org/r/#/c/413277/ - fix for Linux to run 'npm test' internals through xvfb-run, add mesa libs to debian package description * https://gerrit.wikimedia.org/r/#/c/413344/ - cleaner error throw in case GL doesn't initialize Hashar has already merged the configuration changes to CI and confirmed it now runs correctly with these patches in; we can take it out of experimental mode once these are merged. I also noticed that upload.wikimedia.org serves the .stl files uncompressed; gzipping would cut bandwidth usage and thus transfer time approximately in half. Patch to main puppet config which I think will resolve this: * https://gerrit.wikimedia.org/r/#/c/413236/ - apply gzip for application/sla files -- brion
