15:20 → 15:25 Hot topics

15:25 → 15:55 Developers roundtable

• Developers Roundtable
  • Removing the network strategy in dev docker-compose file
  • Globus deletion issue #5987
    • Small fix to ensure that exception is exposed properly
    • Larger issue behind (async deletion) for now will not be fixed
  • #5967 rename "Data rebalancing" activity to "Data Rebalancing"
    • Would need change in most schema files
      • ATLAS, BelleII, CMS, ESCAPE, generic, generic_multivo, icecube, lsst
        • Most communities probably don't use this activity
  •  Support RFC format for X509 identities #5842
    • There are two formats: an RFC-compliant (e.g. CN=John Doe,OU=Users,DC=example,DC=com) and a legacy (e.g. /DC=com/DC=example/OU=Users/CN=John Doe)
    • In Rucio 1.29 and prior, X509 identities must be stored in the legacy format and the authentication server tries to silently convert them from the RFC to the legacy format, if necessary
    • In Rucio 1.30, this conversion has been removed
    • Communities who would like to keep using the legacy format must ensure that LegacyDNStringFormat in mod_ssl is enabled
    • ATLAS plans to convert its existing X509 identities to the RFC format
      • A small probe will become publicly available and should be usable by other communities
