      Alastair

      • Client patch
        patch #1086 all tests pass - John about to certify it
      • Server patch
        patch #1124 is now with John Walsh. Waiting for bugs 18006, 22147 and 23963
      • GIN patch
        patch #1093
        In configuration. Needs pushing along a bit.
      • Evaluate impact of schema content updates upon the registry
        Just started
      • Define configuration for mon box and get it going
        Work has started
      • Cleanup ETICS stuff
      • Tag monitoring tools
        Created configuration on HEAD but needs to be branched
      • Prepare configuration and building of new code before the code is finalised
        Will probably use 2 war files.
      • Find why Alessandra's mon box is unhappy - 15/1/2007
        CERN monb001 is also not happy. Threads and memory etc run out. Runs out of memory in about 90 minutes.
      • Code Registry - 27/4/2006
        Registry is just about there - but without replication of course. Uses a dummy schema. Using Martin's remote registry service which needed some changes. Not yet described in design. It must also be protected from bad ACL files. Will remove context in Registry and use ThreadLocal.

      Antony

      • Get UI info so that we can get back in the RTM
        New parser written. Schema has been updated. WMS patch #24148 has gone into certification. Need this patch and the dependent L&B patch.
      • #24643 Tomcat can fail in various ways detectable by parsing its log file
        Checked in another change - just needs ETICS configuration
      • Find a way to look for GIN/ServiceStatus problems in R-GMA so that we are useful to the info supermarket.
        Started thinking about it - this is related to service publishing
      • #22205 Upgrade to Glue schema 1.3
      • Write an R-GMA-probe or PrimaryProducer-probe https://twiki.cern.ch/twiki/bin/view/LCG/GridMonitoringProbeStandard
      • #24641 LD_ASSUME_KERNEL no longer needed
      • #24007 org.glite.rgma.flexible-archiver contains deprecated calls
      • #24029 org.glite.rgma.servicetool contains deprecated calls
      • #22167 GLUE archiver has problems with stale lock files

      Kush

      • Fix bug in HEAD in ServletResponseWriter
        Source should include stack trace, truncated if necessary. Now decided that should not send the stack trace but just a simple message.
      • Do we need and can we pass the epoch time in each streamed block
      • Check what happens if streamed (or one-off) data are not as expected wrt schema of the consumer
      • Code consumer and task q monitoring service details following recent e-mails and in line with WLCG monitoring requirements
        Need to consider whether to use key value pairs in the response or XML and look at the WLCG document.
      • Review and eliminate fixmes from task q chapter of design document - NEW
      • Update the inspector to work with new and old consumers
        In progress.
      • Add logging to consumer in "approved" style (still log4j)

      Ming

      • #25502 Producers don't die
        Changing from daemon to normal registry thread makes things better - but not necessarily the only reason. Also note that there is a registration thread for each producer.
      • #25616 Declare table can be very slow - Marked as a duplicate of #25502
      • Add a getCreationTimestamp(tableName) for the schema
      • Add logging to schema in "approved" style (still log4j)
      • #19645 The Sub exception org.edg.info.ReadTimedOutException is an inappropriate type

      Parminder

      • Convert tests to python
      • Rule of thumb for how many mon boxes a site should run
      • Ensure that the start call to Producer being added by Alastair is tested and the 2 new exceptions added by Ming are tested.
        Will be DONE once tested on HEAD.

      Paventhan

      • BDII with C++ with SAGA query style
        Just needs tidying
      • Join SAGA mail list and resolve SAGA issues
      • R-GMA plugin
      • gLite style C wrappers
