How to clear cache in Jira using CachManager class

[Nir Zolotorevsky]

I need to clear Lucene cache before reinexing issue.

I found that in previous versions clear caching and reindexing was done as following: 

boolean wasIndexing = ImportUtils.isIndexIssues();
    ImportUtils.setIndexIssues(true);
    ManagerFactory.getCacheManager().flush(CacheManager.ISSUE_CACHE, issue)
    log.debug("Reindex issue ${issue.key}")
    indexManager.reIndex(issue);
    ImportUtils.setIndexIssues(wasIndexing)

I am using Jira 5.0.5.

what is the coorect way in Jira 5 to run :

ManagerFactory.getCacheManager().flush(CacheManager.ISSUE_CACHE, issue)

Thanks

Flushing cache manager is no more needed in JIRA5. It wasn't doing anything in the later versions of JIRA too. Try this:

boolean wasIndexing = ImportUtils.isIndexIssues();
ImportUtils.setIndexIssues(true);
//Do your changes on issue here!   
log.debug("Reindex issue ${issue.key}")
indexManager.reIndex(issue);
ImportUtils.setIndexIssues(wasIndexing)

hi Jubin,

I have tried that many times, reindex command runs with no exceptions

but Lucene is not updated.

(in my plugin I update issue status in code. The status is updated correctly in DB but when I search the updated issue using JQL or IssueNavigator I get the issue with old status)

when I run manually reindexAll() everything get fixed but this operation takes alot of time which is not acceptable on end users

my code comes from EventListener when event is updated I check if in linked event status was updates and I update status:

see attached file with full code

Are you doing the changes to the issue where I have the comment? From your code, you are not doing any issue changes there. Maybe posting the full code will help.

2 changes. Reindex transResult.getIssue and not newIssue. This might be causing the problem.

Second change, I don't see you are using wasIndexing. You are setting it to true, which is a bad practice. Get the original indexing status, temporarily change to true and set it back to what it was!

[Jobin Kuruvilla [Adaptavist]]

I wonder if you have some other listener or code doing an indexing after this one the old issue object! Can't think of anything else.

Hi Jubin,

changed checkAndUpdateStatuses method got same results after search( I get old status) .

updated code:

IssueIndexManager indexManager= ComponentAccessor.getIssueIndexManager();
boolean wasIndexing = ImportUtils.isIndexIssues();
ImportUtils.setIndexIssues(true);
 
int actionid;
IssueService issueService=ComponentAccessor.getIssueService();
actionid=getActionIdForTransition(newIssue,transitionname);
IssueInputParameters issueInputParams= issueService.newIssueInputParameters();
issueInputParams.setComment("changed by: " + authContext.getLoggedInUser());
TransitionValidationResult transValidResult=issueService.validateTransition( authContext.getLoggedInUser(),newIssue.getId(), actionid,issueInputParams);
if(transValidResult.isValid())
{
     IssueResult transResult=issueService.transition(authContext.getLoggedInUser(), transValidResult);
      if(transResult.isValid())
         {
 		indexManager.reIndex(transResult.getIssue());
		ImportUtils.setIndexIssues(wasIndexing);
           }
}

thanks a lot Jubin!!!!

You was right I made reindexing twice inside checkAndUpdateStatuses method and afer executing this method.

How is that doing reindexing twice is reverting the index?

notice that in both cases I reindex the new issue (after changing it's status)

the important thing that is working :)

what if I want to reindex not an issue but something else like custom field. suppose I am adding NEW option to select list and I dont want to restart my jira but want to reset cache. I assume this one would only help for individual issue.

I saw my misspelling :)
