Discovered a nice little git trick today.  I haven’t seen this documented, so I’m not sure if it’s a feature per se, but if you set your user.name via git config like so:

[user]
    name = accountname
    email = email@company.com

and then commit with the --author="Full Name" flag set to another name, this will set git’s commit metadata such that “Author:” is “Full Name” and “Committer:” is “accountname”.

Useful when you want to see the Author in your git logs and the Committer in tools like Hudson or Jenkins.

If you’re trying to automate Symfony2/Doctrine2 migrations with Jenkins, you may run afoul of the interactive confirmation that the doctrine-migrations package throws out:

$ app/console doctrine:migrations:migrate

Application Migrations

WARNING! You are about to execute a database migration that could result in schema changes and data lost. Are you sure you wish to continue? (y/n)

This will break the Jenkins build. While there is probably a way to get Jenkins to reply to this with a “y”, it’s easier just to use the under documented --no-interaction switch. In a build.xml for example:

<target name="schema" description="Update database">
<exec executable="app/console" failonerror="true">
<arg line="doctrine:migrations:migrate --no-interaction" />
</exec>
</target>


Now if the migrations work, so does the build.
