Subject [jira] [Commented] (HBASE-12808) Use Java API Compliance Checker for binary/source compatibility
Date Mon, 19 Jan 2015 19:37:36 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14282921#comment-14282921

Andrew Purtell commented on HBASE-12808:
----------------------------------------

How would one use this to check the compatibility of an unreleased build? 

I applied the patch on this issue to branch 0.98, and did this:
{noformat}
$ mkdir dev-support/compatibility/1  
$ mkdir dev-support/compatibility/2
$ cp -a .git dev-support/compatibility/1  
$ cp -a .git dev-support/compatibility/2
$ ( cd dev-support/compatibility/1 && git co -f 0.98.9 ) # <-- this is a tag
$ ( cd dev-support/compatibility/2 && git co -f HBASE-12729-0.98 ) # <-- this is
a local branch
$ bash dev-support/check_compatibility.sh -n 0.98.9 HBASE-12729-0.98
The JARs to be analyzed from 0.98.9 are:

> Following [~busbey]'s suggestion in HBASE-12556, I've spent some time playing with the
[Java API Compliance Checker|http://ispras.linuxbase.org/index.php/Java_API_Compliance_Checker]
and think it would be a great addition to /dev-support. I propose that we use it to replace
the JDiff wrappers we currently have there (since it does what JDiff does and more), and look
into putting up automation at builds.apache.org to run the tool regularly (e.g. latest release
of a particular branch vs. latest commit of that same branch).
