Upstream corresponding version: v. 6.1.3

Highlights

  • dCacheView: uses inotify-over-SSE to keep page up-to-date.
  • storage-events:
    • added missing events in inotify-over-SSE.
    • performance and robustness improvements for inotify-over-SSE
  • Optional TLS for p2p transfers
  • Zone-aware cell messaging
  • New serialization format

Incompatibilities

  • Starting release 6.1 the BerkeleyDBMetaDataRepository is the default metadata repository for the pools. Sites that was not explicitly specifying pool.plugins.meta property have to set the old default value: pool.plugins.meta=org.dcache.pool.repository.meta.file.FileMetaDataRepository
  • Pool in 6.1.x are not compatible with older dcap doors. However, new dcap doors can operate with existing pools.
