> Improvements to DirectoryTaxonomyWriter (synchronization and others)

> Project: Lucene - Java
> Issue Type: Improvement
> Components: modules/facet
> Reporter: Shai Erera
> Assignee: Shai Erera
> Fix For: 4.0, 5.0

> Attachments: LUCENE-4061.patch, LUCENE-4061.patch

> DirTaxoWriter synchronizes in too many places. For instance addCategory() is
> fully synchronized, while only a small part of it needs to be.
> Additionally, getCacheMemoryUsage looks bogus - it depends on the type of the
> TaxoWriterCache. No code uses it, so I'd like to remove it -- whoever is
> interested can query the specific cache impl it has. Currently, only
> Cl2oTaxoWriterCache supports it.
> If the changes will be simple, I'll port them to 3.6.1 as well.
