Steve Rowe updated SOLR-9847:
-
Attachment: SOLR-9847-release-lock-before-replica-version-agreement.patch
Patch that narrows the period during which the schema update lock is held to
exclude waiting for other replicas to receive the update. With this patch,
there were no stalls when I beasted {{TestBulkSchemaConcurrent}} for 500
iterations (versus 5% of the time unpatched and with [~markrmil...@gmail.com]'s
patch on this issue). Running all Solr tests now.
> Deadlock on ManagedIndexSchema lock.

> Seems we hold the lock while in
> ManagedIndexSchema.waitForSchemaZkVersionAgreement, so we may never see
> agreement because are updates may also be waiting on that lock.
