[xwiki-devs] XWiki Query Language & JCRStore status

Hi, devs. I committed first version of XWQL (or XQL) language to our sandbox (xwiki-query/xwql) for review. I worked ~2 last weeks for it. install info is in xwiki-query/README. Currently it works according my proposal[1], but it is quite easy to modify. It is not perfect, but it works and will be improved. You can test it via QueryManager. (for example in velocity: $xwiki.xWiki.store.queryManager.createQuery("select doc.fullName from Document as doc, doc.XWiki.ArticleClass as a where a.title like '%Launch'", "xwql").execute() ) plan for xwql (for fix in next week): * use xwiki-bridge instead of xwiki-core in xwql. (some methods in bridge are needed) * create query velocity service accessible like $services.query.xwql('...') (according Vincent's velocity services proposal [2]) * move xwiki-query maven module from sandbox to platform/components/ * move QueryManager component from xwiki-core to xwiki-query I would like to integrate xwql for hql in 1.6M2 (8 Sept) and improve it in RC if needed. JCRStore: old JCRStore with some modifications is partly working (save/load document is ok) on recent Jackrabbit, but missing some new stores and need redesign. plan: * create xwiki-store/jcr maven module in platform/components (at sandbox first) it have to depend on xwiki-core (but not reverse). Is it a problem for platform/components? * split JCRStore into components. (RepositoryFacory, SessionFactory, SessionPool, Stores, DAOs) * jcrstore will contains DefaultStores which will contain only business logic on data model, and use DAOs components for store/load data. DefaultStores will be reused in future HibernateStore to remove duplicating of code. * get rid of patched graffito-jcr-mapping (~ORM for JCR). it is old and unsupported. candidates: jcrom [3], jackrabbit-ocm (former graffito), simple hand-made annotation based mapping. I'll look at jcrom first. I already have some code and plan to work on it in sandbox, after finish with xwql-hql. I plan to create working version of JCRStore at the end of September. xwql on JCRStore will work only on JCRv2 implementation.
