Mark Miller updated SOLR-4471:
------------------------------

    Attachment: SOLR-4471.patch

Another test and fix for when a new index directory is forced. Turns out we are 
doing things different somehow currently and don't need that commit at all any 
more to update our commit points. Some other improvement or bug fix.
                
> slave index version is different form master (full index copy needed)

> Scenario: master/slave replication, master delta index runs every 10 minutes, 
> slave poll interval is 10 sec.
> There was an issue SOLR-4413 - slave reads index from wrong directory, so 
> slave is full copy index from master every time, which is fixed after 
> applying this patch from 4413 (see script below).
> Now on replication the slave downloads only updated files, but slave is 
> create a new segement file and also a new version of index (generation is 
> identical with master). On next polling the slave is download the full index 
> again, because the new version slave is force a full copy.
> Problem is the new version of index on the slave after first replication.
> {noformat:apply patch SOLR-4413 script, please copy patch into patches 
> directory before useage.}
> mkdir work
> cd work
> svn co http://svn.apache.org/repos/asf/lucene/dev/branches/lucene_solr_4_1/
> cd lucene_solr_4_1
> patch -p0 < ../../patches/SOLR-4413.patch
> cd solr
