Subject Re: svn commit: r774580 - in /openjpa/trunk/openjpa-jdbc/src: main/java/org/apache/openjpa/jdbc/meta/ main/java/org/apache/openjpa/jdbc/schema/ test/java/org/apache/openjpa/jdbc/meta/
Date Thu, 14 May 2009 19:37:00 GMT
We have to be very careful about this. Apache needs to track the  
provenance of every contribution. Patches should only be uploaded to  
JIRA issues by the author.

1. It is against the rules to commit contributions without the author  
of the contribution signing an ICLA.

2. It is against the rules to commit contributions without  
acknowledging the author in the commit message (if the committer is  
not the author).

3. We don't want @author tags. These tags don't foster community. If  
tags exist in contributions, they should not be committed until the  
tags are removed.

If there are any questions about the above, please raise them now.
