The previous CI attemtped to use Homebrew for builds, but
unfortunately Homebrew has dropped support for universal packages aka
multiarch (fat) binaries. This means that in order to build an arm64 +
x86_64 package, macports has to be used instead of homebrew.
Unlike Homebrew, MacPorts is not installed by default on the GitHub
Actions runners, so we need to install it ourselves. This means
managing our own instance of the cache, which itself produces
challenges as the `gtar` binary run by the action doesn't have enough
permissions to restore the MacPorts checkout. So we have to shim gtar
with a sudo wrapper.
With this commit, we produce a Mosh package that works on macOS 11.0
and newer, on both arm64 and x86_64 architectures. The protobuf
library is statically linked, but all other libraries are provided by
the system.
This builds an OS X package and deploys it to a GitHub release when a
tag is pushed. It also generates a tarball reporting the build
environment and configuration. The build log is still separate.
This is not yet final, it deploys to cgull/mosh and not
mobile-shell/mosh.
It should not affect Linux or OS X CI builds (other than the change to
the Travis Xcode 7.1 image).
Included changes:
The Travis Xcode 7 image seems to have added tmux while we were gone,
breaking our Homebrew setup.
There seems to be no clean reliable way to determine whether a
Homebrew package is installed or needs updating. Reinstalling is less
efficient but seems to work reliably.
The OS X build is now split between four files:
.travis.yml contains Travis-specific CI/release build configuration.
macosx/brew.sh contains Homebrew-specific package manager installs and
reporting.
macosx/osx-xcode.sh contains Apple-specific OS/X and Xcode reporting.
macosx/build.sh does the actual package build.
This broadens the OS X build support to include old and current OS
X/Xcode, and Homebrew/MacPorts.
