    • 3.7 release candidate still in progress

OSG DevOps

New: - Request to inject entire HTCondor job classad into GRACC records. Will require gratia-probe-condor changes.

Ongoing: - Elasticsearch will need to be updated, scheduled for last week in August. Planning ongoing. - StashCP go client is working and tested, and being tested by Christina now. Need to talk to Mats on packaging and releasing. (will follow up). No news from Christina, - Design document is done and is being distributed for xrootd monitoring collector NG (next gen). Shoveler is working and lightly tested. Collector is 90% done. Design document is still not reviewed, but moving foward anyways. - Discussions of xrootd-multiuser support for checksumming on-the-fly. After a discussion, the checksum-on-the-fly funcationality will be ported to xrootd-multiuser. Copied largely from xrootd-hdfs. This does mean that out-of-order writes will not be supported.

Back burner: - (Stalled, but need to get back to it) XRootD accounting information (from Frank): - May need help with automating the process of generating these reports. A month only takes a few minutes. Longer periods take much longer. - Table of working set, read, and re-read for monthly, quarterly, and year. - XRootD TCP plugin is ready for packaging. Derek will follow up with software team on who to hand that off to. -
