XRootD Developers Meeting

Wednesday 19 Jun 2024, 19:00 → 20:00 Europe/Zurich

Development

• Milestone for XRootD 5.7.0
• HTTP case-insensitive headers, use strcasecmp or not?
• PMark for HTTP/TPC - libcurl CLOSESOCKETFUNCTION not called if libcurl compiled with NSS support (i.e. on CentOS 7)
  • Need to verify that there will not be a memory leak in this case
  • Create a test that checks if libcurl links to libnss in the future (and fails in that case)

Issues

• GitHub Issues
• EOS Jira Issues
• Issues that need to be discussed
  • TPC issue via davs:// to redirector with multiple servers behind it (resolved in devel already)
  • Re-resolve IP address when reconnecting a socket (needed in Kubernetes) (moved to XRootD 6.0 milestone)
  • Adding server information to an XRootD request (added to XRootD 6.0 milestone)

Pull Requests

• Add ability to generate a new token on redirect
• [XrdCms] add a tunable weighed random load balancing algorithm
• Defer or disable TLS client authentication
• Add OSS statistics/monitoring plugin
• [XrdTpcTPC] Added tpc.header2cgi configuration

Release Plans

• Release 5.7 is coming by the end of June
• Need a solution for OpenSSL 3.0 performance issues seen on Alma 9
  • Partly mitigated already, if no fix is possible in XRootD for remaining issues, will use OpenSSL 1.1 or 3.2
  • See also https://its.cern.ch/jira/browse/EOS-6166 for more information
• What to prioritize for the XRootD Workshop?
