commit 66322718234c0bc7a74be3e5d60b62b9e897abb3 Author: Isis Lovecruft isis@torproject.org Date: Mon Jul 17 21:43:05 2017 +0000

Fix and expand upon our Travis CI configuration.

* CHANGE .travis.yml so that commands for different purposes (e.g. getting dependencies, building, testing) are in separate config lines and sections. * CHANGE .travis.yml to use their mechanism for installing dependencies via apt. [0] This also allows us to not need sudo (the "sudo: false" line). * CHANGE Travis CI tests (the "script:" section) to build and run tests in the same manner as Jenkins (i.e. with --enable-fatal-warnings and --disable-silent-rules and run `make check`). * CHANGE Travis config to install nightly rustc and cargo. * CHANGE Travis config to split rust install into commands for getting dependencies ("before_install:") and commands for installing them ("install:"). * REMOVE shell redirection when downloading the rustup.sh script. * CHANGE cargo to be in "online mode" so that we can get our Rust dependencies. There's not really a way to get the dependencies without using cargo right now. See https://bugs.torproject.org/22830 for more info. * REMOVE cargo "offline mode" envvars from rustup.sh invocation. * ADD commands to get more info about rustc and cargo before building. * FIX sourcing the cargo/toolchain environment that rustup creates. (Without this, our build scripts don't know about anything called "rustc" or "cargo".) * ADD Travis configuration to do all the target builds with both GCC and clang. * ADD make flags to build with both of the cores available. * ADD notifications for IRC, and configure email notifications (to the author of the commit) only if the branch was previously building successfully and the latest commit broke it. * ADD the ability to run the Travis build matrix for OSX as well, but leave it commented out by default (because it takes roughly ten times longer, due to a shortage of OSX build machines). * ADD Travis config option to cancel/fail the build early if one target has already failed ("fast_finish: true"). * ADD comments to describe what our Travis config is doing and why it is configured that way.
