From my shell history earlier this afternoon, attempting to push to try: froydnj@hawkeye:~/src/mi.hg$ ./mach try syntax '-b od -p android-dependencies,android-lint,android-findbugs,android-test,android-checkstyle,android-api-16,android-x86 -u none -t none' Must specify platform when selecting tests. froydnj@hawkeye:~/src/mi.hg$ ./mach try syntax '-b od -p android-dependencies,android-lint,android-findbugs,android-test,android-checkstyle,android-api-16,android-x86' Must specify platform when selecting tests. which is just wrong, because that try syntax (particularly the first one) works just fine, especially why I created a try syntax commit manually and pushed that.
