Client patch - 13/2/2007
patch #1086 is now with John Walsh
Server patch (once format exception testing complete) - 13/2/2007
Just waiting for Parminder's testing
GIN patch - 13/2/2007
Tagged code - Antony will provide info on how to test then the patch can be created
Upgrade machines - 18/3/2007
Memory for Parminder and 2 Keyboards needed - then done. Order up another graphics card.
Review APEL code - 18/3/2007
Define configuration for mon box and get it going - 13/2/2007
Work has started
Cleanup ETICS stuff - 13/2/2007
Prepare configuration and building of new code before the code is finalised - 13/2/2007
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.

Get UI info so that we can get back in the RTM - 1/2/2007
Antony to phone Ales
Watch bug on job publishing tables with VO and predicate - 15/1/2007
22869 - Antony will agitate
Complete monitoring questionnaire as circulated by Luigi - 13/3/2007
#24643 Tomcat can fail in various ways detectable by parsing its log file
Follow up with Enzo on the info supermarket. Might use half an archiver. Cleanup based on ServiceStatus. Or might use cleanup on the supermarket directly - 13/3/2007
#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
#22167 GLUE archiver has problems with stale lock files

Fix bug in HEAD in ServletResponseWriter - 13/2/2007
Source should include stack trace, truncated if necessary
Look at the spec and the way in which the VDB relates to authz. If it then seems sensible, move op authz a filter on the server - rather than the service - 20/3/2007
Code consumer and task q monitoring service details following recent e-mails and in line with WLCG monitoring requirements - 13/2/2007
Add logging to consumer in "approved" style (still log4j) - 13/2/2007

Code Schema - 8/1/2007
Schema coding work has started Will use a single DB e.g. RGMA_Schema specified in the config file. The VDB tables has the VDB name prepended. Class framework and constructors done. The replication is now being worked on. Working on MySQL class - it now supports transactions. Need to consider the performance of INNODB.
Use synchronised methods to access DB. Later provide a different implementation with INNODB.
Hope to finish replication this week.
Need to modify and clean up the remote schema API
Add logging to schema in "approved" style (still log4j) - 13/2/2007
#19645 The Sub exception org.edg.info.ReadTimedOutException is an inappropriate type

Set up a test to simulate 1000's of producers feeding an archiver - 15/1/2007
Managed to provoke an out of memory exception on the server. Run with constant but tolerable load to see if it degrades. We also want a client simulating the log publisher.
Need to find out the size of the insertlist and emulate monb001 properly
For now simpler test with fixed number of producers, multiple threads and a lot of inserts. Monitor error messages on producer side and see what data gets to to the archiver.
Rule of thumb for how many mon boxes a site should run - 20/2/2007
Ensure that the start call to Producer being added by Alastair is tested and the 2 new exceptions added by Ming are tested. - 8/1/2007
Will be DONE once tested on HEAD.

BDII with C++ with SAGA query style
Written code to generate the AST. Now working on the BDII query string.
