https://indico.cern.ch/event/1248514/

• First collaboration meeting in 4 years

• Workshop planned and announced (also first for 4 years)

Upcoming releases

• Currently an issue with openssl3 (fixed hoped for the release)

• tested with Alma 9 (with existing tests), from this release

• 5.5.X (with rc), from which releases are tags

• Currently ~ 90 tickets; including ~ 22 bug tickets

• Prep for HL-LHC and focus on performance

• Tokens also will expect some further requirements / developments

• Comments:

  • 500 server errors cause operational complexity (from CMS)

  • LE might allow to spoof a hash on a certificate, allowing to take another auth.

  • OSG: repackages rpms with relabelled release number as EPEL version (different patches in place)

  • Performance markers for xroot->xroot transfers (e.g. in CTA FTS logs).

    • (not done); won’t be important once tape rest API is used (i.e. move to HTTP)

  • Container hostnames; this is partially done, but may not work with complex setups involving e.g., k8s.
