The primary change is to set
CARGO_TARGET_DIR=target
which instructscargo install
to use the target/ directory which is cached between builds on travis. This is only available on recent nightlies so I've bumped clippy and rustfmt versions.Unfortunately,
ring v0.11.0
does not compile on recent nightlies and upstream provides no support for older versions. Therefore I've added a patch section to use a git repo that incorporates the fix and a few other cleanups. This issue would have broken the build soon anyway when rust 1.24 goes into beta.A few other changes:
npm install
on the stable job
