Erick Erickson updated SOLR-10857:
----------------------------------
Attachment: SOLR-10857.patch
Final patch, committing momentarily. Will commit to 6.6 branch for re-spin if
we do that.
This affected all core unloading, not just stand-alone.
If you look at the patch you'll notice a kind of scary bit where I took out the
if test when I moved the removeCoreDescriptor, see below. This does just what
the old code did since the core descriptor was removed anyway even when
deleteInstanceDir==false in 6.0+ at least.
{code}
if (deleteInstanceDir) { // we aren't going to reload this if we delete the
instance dir.
solrCores.removeCoreDescriptor(cd);
}
{code}
This was another consequence of having copies of the CoreDescriptor hanging
around in several places.
I thought about removing the CoreDescriptor from SolrCore in SOLR-10007 and
making the internal lists of CoreDescriptors in SolrCores and the transient
plugin be the one true source of CoreDescriptors, but decided against it at the
time due to how intrusive that patch was already, leaving that discussion for
another day/JIRA.
