== News

  • ARC6 builds are disabled, Fedora 41 builds are removed as well
  • ATLAS BOINC is upgraded to ARC7, almost w/o glitches, except that somehow session dir ACL got changed. pyARCrest is patched. The next step is to upgrade aCT servers to ARC7
  • New version of Nagios probes package has no GridFTP plugin, which breaks EGI monitoring. This can be fixed by changing the EGI config package (Mattias)
  • There are some issues with Gitlab runners, work in progress

Draft proposal for transfer request XRSL (T-XRSL) is discussed, notes added, see

https://docs.google.com/document/d/1rdhZX3r0iRt96iaZJr12NwNNoPeuEySicPnOP1hO7ME/edit?tab=t.0

The streamFile attribute use case is still unclear, postpone to future discussions. See also notes from October 21 (temporary file caching is not needed for streaming, and may lead to creation of a whole new SE service).

Draft to be finalised by Lars.
