Flapping tests #456
Description
Recently travis tests have failed every once in a while due to network failures. Ticketing here so other devs have some visibility that this is happening and to log any ideas for mitigating.
The most common error appears to be when running the android compile test (https://github.com/mapbox/mason/blob/master/test/c_build_android.sh). This test usually succeeds and outputs:
* Downloading binary package osx-x86_64/android-ndk/arm-9-r13b.tar.gz...
* Installed binary package at /Users/travis/build/mapbox/mason/mason_packages/osx-x86_64/android-ndk/arm-9-r13b
* Downloading http://nongnu.askapache.com/freetype/freetype-2.5.5.tar.bz2...
* Building for Platform 'android/arm-v7-9'...
FreeType build system -- automatic system detection
But every once in a while it fails because the download of arm-9-r13b either fails or times out and then the build falls back to trying to build arm-9-r13b from source. The arm-9-r13b.tar.gz looks to be 125 MB.
The source build then fails with:
The MASON_PKGCONFIG_FILE variable not found in script.sh. Please either provide this variable or override the mason_cflags function hook
which looks like outfall from #356.
