From f13a3490fdb404bbd4c77e45b83540d6deec1358 Mon Sep 17 00:00:00 2001 From: Dan Dedrick Date: Mon, 21 Jan 2019 15:15:27 -0500 Subject: devtool: improve git repo checks before check_commits logic The check_commits logic assumes that both devtool-base and args.branch exist in the git repo that it is operating on. In order to prevent errors at that point it's best to first ensure that both of these refs actually exist. If they don't both exist then the check_commits logic should just be skipped, as it would be if the repo wasn't originally checked out by devtool. Previously if a user removed the args.branch branch from their devtool cloned repo this code would crash on adding the repo with -n. The crash would look like this: Traceback (most recent call last): File "/home/ddedrick/src/poky/scripts/devtool", line 344, in ret = main() File "/home/ddedrick/src/poky/scripts/devtool", line 331, in main ret = args.func(args, config, basepath, workspace) File "/home/ddedrick/src/poky/scripts/lib/devtool/standard.py", line 812, in modify (stdout, _) = bb.process.run('git log devtool-base..%s' % branch, cwd=srctree) File "/home/ddedrick/src/poky/bitbake/lib/bb/process.py", line 178, in run raise ExecutionError(cmd, pipe.returncode, stdout, stderr) bb.process.ExecutionError: Execution of 'git log devtool-base..devtool' failed with exit code 128: fatal: ambiguous argument 'devtool-base..devtool': unknown revision or path not in the working tree.
