It will allow bcc users to\r\nprovide debug symbols if only they can write to at least one directory. Nothing\r\nelse needs to be assumed regarding the system bcc runs on.\r\n\r\nMy intention is to make debuginfo lookup work on Android in one form or another.\r\nNone of the gdb rules works out of the box:\r\n- native libraries are often managed by Android apps themselves and uncompressed\r\n by apps into private directories. Sideloading debuginfo into those directories\r\n might not be feasible. What's more it's desirable to remove data like\r\n debuglink from release builds of mobile apps. At the same time those builds\r\n are the most interesting ones to investigate with bcc.\r\n- there is no /usr directory on Android, so there is no /usr/lib/debug/. It\r\n could be created with some effort, but symfs is much more convenient and\r\n already used when profiling with simpleperf (fork of perf for Android).ghprbCommentBody[buildbot, ok to test]ghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="Support perf's symfs mechanism for debuginfo lookup." href="https://github.com/iovisor/bcc/pull/2482">PR #2482</a>: Support perf's symfs mechan...#453378047460664bcc-pr #4545false45388FAILURE1565021118288https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/45/git45https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc25/45/45https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc26/45/45https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc27/45/45https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=fc28/45/45https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=ubuntu1604/45/45https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=ubuntu1710/45/45https://buildbot.iovisor.org/jenkins/user/danobi/my-views/view/all/job/bcc-pr/label=ubuntu1804/45/
