It takes an expanded Background Music .pkg installer and repackages it
into a new .pkg installer. It's mainly useful for code signing, since
you have to expand the unsigned package, sign each of the bundles,
repackage it and then sign the new package.
Also, fix build_and_install.sh putting the BGMXPCHelper dSYMs in the
wrong archive.
Archiving is the standard way to build a release for distribution using
Xcode. package.sh now uses this option when it creates a release
package.
This change is mainly to keep the Run settings in the Xcode schemes from
affecting the release builds, which means we can commit the schemes with
more sensible settings.
Also, disable AddressSanitizer in the BGMDevice scheme, which was
stopping coreaudiod from launching because its sandbox won't allow the
process to load the AddressSanitizer dylib.
Users reporting bugs will be able to use these packages to install debug
builds of Background Music without having to install from source. This
is mainly useful because debug builds have more detailed logging.
Hopefully we'll get around to adding an option to enable debug logging
at runtime, but this should work well enough for now.
Also:
- Use newer macOS images in Travis CI builds.
- Fix an xcrun command in build_and_install.sh that was accidentally
being started in the background.
- Fix build_and_install.sh building libPublicUtility.a twice for no
reason.
This is mostly so BGMApp won't leave BGMDevice as the default if BGMApp
crashes, which would stop audio from playing until the user changed the
default device themselves. Also handles SIGINT, SIGTERM and SIGQUIT.
For crashes where the BGMApp process may be in an unknown state, e.g.
segfaults, BGMXPCHelper handles changing the default device.
Should fix the Travis Xcode 9 build, which is currently failing because
the AppleScript we use to quit BGMApp in .travis.yml gets "user
cancelled" for some reason.
Also makes some minor improvements to the reports generated by
CrashReporter. The way CrashReporter works with Background Music should
otherwise be unchanged.
Skipping them by overriding runTest didn't work and this is the only other way
I can think of. xcodebuild's -skip-testing option would work, but only with
recent versions of Xcode.
6.4 should already have been retired according to their documentation, so it
will probably need to be removed. But it would be nice to have because it's the
only OSX 10.10 image.
Also, log the installed audio devices and their audio IDs.
I think the tests are probably failing because the Travis VMs don't have
any audio devices. If so, this won't actually fix the tests, but it
should help us narrow it down.
