[jira] [Commented] (LEGAL-548) Question about modifying the Avro c++ project that uses Apache V2 License

    [ https://issues.apache.org/jira/browse/LEGAL-548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17253306#comment-17253306 ] 

Ralph Goers commented on LEGAL-548:
-----------------------------------

The Apache License 2.0 contains no clause that requires source code be made available.  Anyone can ask for unmodified avro source. You are free to tell them no or point to its location at the ASF. In my reading of the license I see nothing that requires you to provide a list of modifications.

> Hello,
> I need to modify the avro project (It uses that Apache V2 License) for use in my closed source, proprietary product.  Can you please help me with these questions:
> If I modify avro, do I need to publicly make available the full avro source code including my modifications?
> Can I redistribute the binary Avro lib along with my product without having to release the source code of my avro modifications?  Can someone ask for unmodified avro sources?
> In addition to attributing/acknowledging the use of Avro and displaying the Apache V2 license, the license says to list modifications?  Where and how should I list the modifications (since I don't want to distribute the source form of my changes)?
> Thanks for all your help with these questions.
