Hi Peter, I'll see if I can get me, Jake, and Olle all on board to finish the refactoring and merge back with the original branch. Functionally the PHP client works and is ready. We'd like to add unit tests and better organize the code. How about the REST api? Any word on whether the path

Hi Nikola, Below is a baseline for unit testing neo4j. Please let me know if you have any ideas for helpers that would make writing tests easier. It might be useful to pull together a package of base classes and maybe hamcrest matchers that are common to all testing. Cheers, Andreas package

[Neo4j] Questions about Neo4j vs Hadoop

After reading the article on highscalability I have a few questions about it: 1. You're saying that matching data on the client side in for example Java would be slow. Are you just talking about skipping multiple round trips to the server, since the matching should take as long on the server as

Hi Andreas, thank you for your effort ! But I am looking for a way to detach neo4j completely from file system. What I understood from thread below, there is a way to start neo4j so it works only in memory, creating no files, so there is no need to delete db files with every test run. Best,

Re: [Neo4j] unit testing

2010-10-19 Thread Andreas Kollegger
Hi Nikola, Ah, I see. Unfortunately there is no way to avoid any file creation. The lowest file access would be to never commit a transaction. Are you interested in easier unit-testing, or are you interested in in-memory to have all the graph semantics without being persistent? Cheers,

[Neo4j] Lucene result sorting

2010-10-19 Thread Balazs E. Pataki
Hi, Is it possible to do get sorted results form LuceneIndex#query()? It would be really helpful if results would be sorted at lucene time according to one or more indexed fields rather than loading the actual neo4j nodes and than iterating over them for sorting. Currently, it seems that

Re: [Neo4j] unit testing

2010-10-19 Thread Andreas Kollegger
For easier unit testing, I could imagine two approaches: 1) providing a few base classes that provide methods for creating/shutting down a temporary graph database, and maybe @Before/@After type annotation; 2) a TemporaryGraphDatabaseService which manages itself. For #2, I'm imagining use

Hi Balazs, We've been working on a new lucene-index module just these last days. The new index module allows sorting, through the QueryContext-class. You can look in svn https://svn.neo4j.org/components/lucene-index/trunk/, if you are so inclined, or wait for the next milestone release

Yes, neo4j.py does abstract away a lot of this hassle, but it does not (yet) provide an abstraction for the RDF component. I tried to retrace your steps, but I am not able to reproduce your error, so I don't really know what might be going wrong for you. It could be that you are missing a jar
