Subject [jira] [Commented] (HADOOP-4258) the test patch script should check for filenames that differ only in case
Date Fri, 04 Sep 2015 21:41:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14731482#comment-14731482

Allen Wittenauer commented on HADOOP-4258:

* This likely won't be getting committed to trunk given that all development on test-patch
there has stopped.  So please change this to use the HADOOP-12111 branch.

* preapply is too late.  This should be in postcheckout.  Doing that also simplifies the code
since returning 1 for failure will trigger all the cleanup, etc., so that wouldn't have to
be done in the plugin.

* I suspect the problem that [~owen.omalley] is actually talking about is a problem where
a new file was added because it conflicted with a pre-existing file in the source tree.  This
patch would miss that situation.

* This seems like it would be very expensive on large patches due to the number of calls to
tr.  Off the top of my head, it looks like it could be optimized to use uniq -id first to
limit the set of files that need to looked be at for at least one of the loops (outer would
likely be better, given point 2 above should be handled prior to even running the inner loop!)

* Totally not a fan of having A and a and B and b as var names. I get the why's but it makes
it really hard to read at a glance! :D

> It would be nice if the test patch script warned about filenames that differ only in
case. We recently had a patch committed that had a pair of colliding filenames and subversion
broke badly on my Mac.
