[xwiki-devs] Query Generator review

Hi, devs. I have a small review of XWIKI-1090: XWiki Query Generator, XWikiQuery/makeQuery in order to move it to new XWQLanguage instead of old QueryPlugin. query automatically to run on the storage engine. allow to generate the query It is easy to rewrite syntax to XWQL, but there are some problems in design. 1. To make it run on XWQL we just need to replace QueryPlugin#makeQuery with something similar. I propose: 1.1 move XWikiCriteria to xwiki-query/manager module (it is not depend on core. except only one util method) 1.2 add Query QueryManager#createQuery(XWikiCriteria) as analogue to QueryPlugin#makeQuery 1.3 fix all affected references. There are one method that need be bridged (xwiki-bridge) for this: BaseClass#makeQuery. I don't like to bridge it, so looking other ways. 2. General overview of query generator: It is very connected with core and distributed across many classes. This is not good for our component architecture. There are: UI Generator: XWiki#displaySearch* PropertyClass#displaySearch* and overrides XWikiDocument#displaySearch Query Generator: XWiki#createQueryFromRequest BaseClass#makeQuery PropertyClass#makeQuery, #fromSearchMap and overrides Executers: XWiki#search*(XWikiQuery, ...) I'm doing 1. now. Query Generator redesign(2) is not important for now, I think. It works well.
