If `repo start foo` fails due to uncommitted and unmergeable changes in a single project, we have switched half of the projects over to the new target branches, but didn't on the one that failed to move. This change improves the situation by doing three things differently: - We keep going when we encounter an error, so other projects that can successfully switch still switch. - We ignore projects whose current branch is already on the requested name; they are logically already setup. - We checkout the branch if it already exists, rather than trying to recreate the branch.

%prog <newbranchname> [<project>...]
|
|
|
|
This subcommand starts a new branch of development that is automatically
|
|
pulled from a remote branch.
|
|
|
|
It is equivalent to the following git commands:
|
|
|
|
"git branch --track <newbranchname> m/<codeline>",
|
|
or
|
|
"git checkout --track -b <newbranchname> m/<codeline>".
|
|
|
|
All three forms set up the config entries that repo bases some of its
|
|
processing on. Use %prog or git branch or checkout with --track to ensure
|
|
the configuration data is set up properly.
