Subject [jira] [Commented] (LUCENE-3795) Replace spatial contrib module with LSP's spatial-lucene module
Date Thu, 16 Feb 2012 16:55:00 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3795?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13209497#comment-13209497
] 

David Smiley commented on LUCENE-3795:
--------------------------------------

LSP is comprised of several modules:
* spatial-lucene: The heart of the project.
* spatial-solr: Solr support, notably field types using spatial-lucene.
* spatial-extras: An extension of spatial-lucene that uses JTS (LGPL licensed) for polygon
support.
* spatial-demo: A demonstration web UI using OpenLayers, Solr, Wicket, and the other LSP modules.

The spatial-solr module of LSP can be considered in another issue following the conclusion
of this one.  The other modules aren't being considered for incorporation into Lucene/Solr.

LSP is largely new code although some of it originated using chunks of the existing Lucene
spatial contrib module and SOLR-2155 (A recursive PrefixTree/Trie algorithm using geohashes).
 It's fair to say this is a superset and descendent of SOLR-2155 but with a real framework
around it and plenty of refactorings and tests.

I ran Atlassian's Clover code coverage to get some statistics of this spatial-lucene module
of LSP:
* LOC: 6,605, NCLOC: 3,959
* Packages: 18, Classes: 70
* Code coverage: 53%

The code coverage surprises me a little... perhaps the number is higher when the spatial-solr
module gets involved which uses more of the classes then the tests do here alone.

> I propose that Lucene's spatial contrib module be replaced with the spatial-lucene module
within Lucene Spatial Playground (LSP).  LSP has been in development for approximately 1 year
by David Smiley, Ryan McKinley, and Chris Male and we feel it is ready.  LSP is here: http://code.google.com/p/lucene-spatial-playground/
 and the spatial-lucene module is intuitively in svn/trunk/spatial-lucene/.
