Tamás Cservenák updated MINDEXER-157:
-------------------------------------
Fix Version/s: 6.2.1
> After import all groups and root groups are inverted in the IndexingContext
> ---------------------------------------------------------------------------
>
> Key: MINDEXER-157
> URL: https://issues.apache.org/jira/browse/MINDEXER-157
> Project: Maven Indexer
> Issue Type: Improvement
> Reporter: Matthias Bläsing
> Priority: Major
> Fix For: 6.2.1
>
>
> I investigated a regression introduced into the NetBeans codebase by the
> update of maven indexer to 6.2.0
> ([https://github.com/apache/netbeans/issues/4102)] It turned out, that maven
> indexer after loading the index needs to explicitly rebuild the group lists
> as they are not stored with the index any longer. Rebuilding on demand is not
> an option for us, so a solution using a cached version was tried.
> The idea is, that after the index is updated, the current group lists will be
> dumped into cache files and when the index is loaded from scratch, that cache
> is used to initialize all groups and root groups. This seemed to work ok, but
> the results were strange - only the root groups were returned. Debugging
> showed, that the all groups list was very short (~950 groups for maven
> central) while the root groups list was very long (~66.000 groups for maven
> central). The opposite ratio was expected.
> The issue can be traced into _DefaultIndexUpdater#loadIndexDirectory_ where
> _IndexingContext#replace_ is called with the with the wrong order or
> parameters. The declared method:
> {code:java}
> public interface IndexingContext {
> void replace( Directory directory, Set<String> allGroups, Set<String>
> rootGroups ) throws IOException;
> }{code}
> is called as:
> {code:java}
> private Date loadIndexDirectory( final IndexUpdateRequest updateRequest,
> final ResourceFetcher fetcher,
> final boolean merge, final String
> remoteIndexFile )
> throws IOException
> {
> // ...
> updateRequest.getIndexingContext().replace( directory,
> rootGroups, allGroups );
> // ...
> }
> {code}
> The last two parameters need to be reversed.
