JRA1-UK Action List

Low Priority

• Design and code mediator - ??? - 27/4/2006
  There is a problem with views. Need to get back the underlying table as well as its description when querying something which turns out to be a view rather than a table. Needs checking by someone.
• Code new streaming - ??? - 6/6/2006
  Mostly done on consumer side. Needs checking by someone.
• Tuple stores - ??? - 12/6/2006
  Coming along nicely
• Complete PP design and code it
• OGSA Naming into GLUE 2 - Antony - 2/10/2006
  Wont be done till OGF.
• Follow up on gEclipse - Steve - 2/10/2006
• Having confirmed that it does not introduce compatibility problems, make the exceptions explicit in each language where it can be done without negative impact. This will only be done on the new code - ??? - 5/1/2007
• Ensure that C and C++ APIs have logging code IFDEFed so that a developer can turn on logging for himself but deployed code has no dependencies - ??? - 1/1/2007
• Consider changing the consumer to make use of "Tuple Stores" It would reduce the volume of code though probably at the expense of some performance loss. The "Tuple Store" is able to deal with both memory and disk based stores and may make the SP trivial. - ??? - 15/2/2007
• Devise a way to conceal the DB user name and password - ??? - 21/2/2007

Medium Priority

• Follow-up on MonAMI - Antony - 5/7/2006
  Only runs on insecure port. Discussion with Paul underway. 
• Should SAM publish to GOC Node? Maybe Dave K could publish. 
• It is possible to access our services on port 8080 if the server.xml has connector. We should be able to secure the service however the connector is setup (as others may be using tomcat).
• New "simpler" init.d scripts for the flexi 
• Try to break JDK socket library
  Various ways to get socket into closed wait state. 1.4 and 5 look similar. It would appear that JVM being out of memory can provoke this.
• Investigate protection against running out of memory
  He thinks that we should detect and restart the service - not clear how to do it. Lots of discussion... Maybe we should make some measurements. Alastair has done some work (it stops the service, trys to start the GC and restarts the service). Tested with big linked list on 1.5 - it did not recover well. Will add an RGMABusy exception to allow service to say it is too busy. Maybe do a better job of estimating total memory used.
• Service Proxy Module - add to GIN etc
  Antony has done this for the job status raw archiver - can it be done in a more generic way? GIN has some bug fixes to make as well. Need to assign bug to Alastair - Antony will check that it is in Savannah.
• Consider load on registry in new design - consider stored procedures in RDBMS 
• Investigate Tomcat long running test (memory leak) and use of log4j
  Made contact with Torsten.
• Need to generate RGMABusy exceptions at the right time on the HEAD server code
  First need to define waht it is to "be busy".
• Eliminate the spec fixmes - Steve - 9/1/2007
• Dependency diagram in design needs updating - Steve - 15/1/2007
• Plan migration from physical DB names to logical - ??? - 21/2/2007
• Talk to Philipa next week about maintenance of registry XML - Antony and Alastair - 1/2/2007
  Ask again - but not before end of March
• Eliminate log4j
• Eliminate log4cxx/pp
• Use jaxp

High Priority

Alastair

• Client patch
  patch #1086 is now with John Walsh. The test tar file and instructions have been sent to John.
• UI and WN for SL4
• Server patch
  
• GIN patch
  Tagged code - Antony will provide info on how to test then the patch can be created
• Upgrade machines
  Memory for Parminder and 2 Keyboards needed - then done.
• Define configuration for mon box and get it going
  Work has started
• Cleanup ETICS stuff
• 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
  Now waiting for wms #24148 - A new tag of wmproxy is going to be released in the next days. Meanwhile Antony is looking at the log file parser
  
• Watch bug on job publishing tables with VO and predicate
  22869 - Antony will agitate. Another mail sent but no response.
• #24643 Tomcat can fail in various ways detectable by parsing its log file
• Find a way to look for GIN/ServiceStatus problems in R-GMA so that we are useful to the infor supermarket.
• #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. Should be fixed today (26/3/07)
• 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. Need to also update the inspector to match
• Add logging to consumer in "approved" style (still log4j)
  Waiting for Steve
• 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
  This is not to be done yet

Ming

• 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. Need to modify and clean up the remote schema API. Hope to finish replication this week.
• Add logging to schema in "approved" style (still log4j) - 13/2/2007
• #19645 The Sub exception org.edg.info.ReadTimedOutException is an inappropriate type

Parminder

• Convert tests to python,  introduce more automation and bring the document and the code in line with each other. This will all be done initially on the 1.5 branch. One subsystem to be completed first.
• 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
  Written code to generate the AST. Now working on the BDII query string.   Can generate filter string for BDII queries
  

Steve

• Improve release plan - 9/2/2007
• Add new new calls to list available VDBs to spec and design- 20/2/2007
• Add to the spec that both client and mon box names should be a stringified numeric IP addresses - 12/3/2007
• Add to the spec that both client and mon box names should be a 13/2/2007 stringified numeric IP addresses - 12/3/2007
• Update design for schema following e-mail - 20/2/2007
