Bug 1430315 - Add a toolchain job to build llvm-dsymutil independently. r?build We've had problems with crashes in llvm-dsymutil for a while, and while they are, in essence, due to the fact that rustc produces bad debug info, they are a hurdle to our builds. The tool comes along clang, and updating clang is not necessarily easy (witness bug 1409265), so, so far, we've relied on backporting fixes, which can be time confusing (witness bug 1410148). OTOH, llvm-dsymutil is a rather specific tool, that doesn't strictly need to be tied to clang. It's only tied to it because it uses the llvm code to do some of the things it does, and it's part of the llvm source tree. But it could just as well be a separate tool, like it was(is?) on OSX. So, we add a toolchain job to build it from the llvm source, independently from clang, so that we can update it separately, if we hit new crashes that happen to already be fixed on llvm trunk. It will also allow to more easily update after upstream fixes crashes after we report them.

Bug 1430908 - Use --progress=dot:mega with wget; r?glandium By default, wget prints dots every 1k bytes. This can render a lot of output for large files. We switch to the "mega" style, which makes each dot represent 64k, thus reducing output by up to 64x. We also force the use of dot display. By default, it uses "bar" which attempts to use terminal formatting if possible. Since most of this code executes in CI and terminal control characters can interfere with logged output, we force the use of "dot." (Although wget appears to automatically switch to dot in TC today. But consistency is good.) MozReview-Commit-ID: IpTWJdcauTV

Try to make |npm install| work in webconsole. MozReview-Commit-ID: P2EUd9WQR4

Bug 1401189 - Part 2: Add webconsole tests. MozReview-Commit-ID: 1t06QnJ4XNJ

Bug 1401189 - Part 1: Add new npm TC kind. This patch adds a new npm kind. A single npm declaration corresponds to a single npm command against a single package.json in the source tree. The npm declaration expands to two task declarations: 1) a toolchain task that runs |npm install| and collects the resulting `node_modules` directory; 2) another task that installs the `node_modules` directory produced by the toolchain task and then runs whatever npm command was specified. This two stage process -- dependency collection before task execution -- has worked well for the Android-Gradle dependency hierarchy. MozReview-Commit-ID: GAuTdOVVsfH

Bug 1430037 - Use sparse checkouts for docker image builds. r?dustin In many cases, building docker images starts on machines that don't have a cached checkout, and it often takes forever to get a full clone. It used to be worsened when 3 jobs could run at the same time because the worker would start up clean, and 3 jobs would be doing a mercurial clone at the same time, thrashing I/O, but that part is fortunately fixed. It is still, however, appreciable not to waste time in the mercurial clone part of image creation.

Bug 1430037 - Use the in-tree image builder image to build docker images. r?dustin The image builder image we use to build docker images is updated manually, and not necessarily when changes occur in tree that should be reflected by a new image builder image. For instance, its run-task is currently outdated. Not enough that it's actually a problem, but it could rapidly become a problem. There is also a lot of friction when trying to make changes in how docker images are built, and while last time I tried, I ended up not being able to do the changes I wanted to make because the docker version on the host is too old, but this is already the second time I've been trying to make things better and hit a wall because the the image builder is essentially fixed in stone on the docker hub. So with this change, we make all the docker images use the in-tree image builder image, except itself, obviously. That one uses the last version that was uploaded. We may want to update it at some point, but not doing so will only impact building the image builder image itself, not the other ones.
