Re: [hibernate-dev] HSEARCH-1270 : indexing (still) happening after Session#clear()

I'm having a half-baked solution for HSEARCH-1270, and it looks like I can't do better than that without waiting for HHH-8577 to be included in ORM [JIRA links at the bottom]. # The problem described by HSEARCH-1270 After the user has enqueued some indexing operations in Hibernate Search's Worker, if he then invokes Session.clear() the queue is not cleared. I realize that clear() might not be as popular as most other methods on Session, still I consider this an annoying limitation: it introduces an inconsistency in the index and the user might not even realize the mistake, and neither do we have an opportunity to warn him. # Partial solution This is working well, and the test passes: https://github.com/Sanne/hibernate-search/compare/HSEARCH-1270?expand=1 #Why it's not complete The test requires to invoke the clear() operation *after* having wrapped the Session in a FullTextSession. In other words, if I'm just using the Session the bug would still manifest. #What now Considering that we can't do better than that - at least without patching ORM with HHH-8577 - would you still merge such a patch? I would propose to merge it, and add a warning in the docs, at least the user has an option to workaround the issue. The downside is that so far, at least Session and FullTextSession behave consistently.. was that a good thing? Another approach to the problem could be to provide an explicit FullTextSession#clearIndexingQueue() I think I'd like that, especially as it can be useful in other situations, for example to avoid triggering any indexing operation for a specific transaction. Also, it would be a good companion for FullTextSession#flushToIndexes() -- Sanne https://hibernate.atlassian.net/browse/HSEARCH-1270 https://hibernate.atlassian.net/browse/HHH-8577
