NorduGrid technical meeting

23-24 June 2005, Copenhagen

Minutes

Since people from Denmark didn't travel to St.Petersburg in May, this extraodinary meeting was called in order to keep everybody in sync with the developments.

Participants: Michael, Mattias, Anders, Oxana, Balazs, Aleksandr, Jakob

Warm-up

SC3 briefing

Build order: lots of cleanup is needed to make nightlies build (datamove, std.h, namespaces, include system headers, include order etc)

1. Build should be able to use the SUBDIRS of autotools
2. Also dependencies should be explicitly expressed in terms of .la libs
3. Merge/solve std.h and config.h
4. Use std:: instead of "using namespace std;"
5. Include system headers where needed directly (not rely on indirect dependencies)
6. Include order:
   • std.h/config.h
   • system
   • globus
   • local
7. Try as much as possible to have:
   • ClassName.cpp
   • ClassName.h
   • (single class per file)
8. Use cpp suffix

.cpp is THE extension!

Naming: postponed; preferably not imposed

Agenda

Actual minutes

Next meeting: Oslo, August 17-19. Invited talks are discussed. Balazs has the list.

Externals:

• gacl, stays inside
• libxml2 - outside
• mysql client: a dependency; still not treated properly
• SWIG - LATER
• gSOAP: 2.7.2 works out of box, 2.5.2 to 2.6 (not including) also did work. Not a runtime dependency though
• VOMS: there are VDT and EDG-specific things that have to be removed (patched); 1.5.x does NOT depend on mysql++; VOMS-ng based on 1.5.4. 1.3.9 is useless. Try to build against 1.5.4, if doesn't work - remove VOMS from 0.4
• Globus: GT4; RC better be removed from 0.6. Existing RC-registered files have to be moved, announcement made. Anders has ideas on how to drop Globus' OpenSSL and to use whatever comes with the system.

Build:

• arclib included for 0.6
• packages: server, client, monitor, gridmap-utils, ca-utils, devel; ngui and ngdata merged into ngui
• issue of retaining NORDUGRID_LOCATION: better get rid of it, hardcode ../ relatively to the binary. Env. variable NORDUGRID_LOCATION will nod be hardcoded
• user scripts (nordugrid.[c]sh) move to userinterface directory in CVS
• SWIG: build-time dependency. Try to check-in generated wrappers, if works - no dependency
• CVS restructuring: modularity, allows for independent builds, testing. Anders to try it on a separate copy of the tree
• Logger: nothing in the client, perhaps separate logger client binary/package is needed

Manpower:

Everybody's busy. Anders' deadline for the paper: Wednsesday, June 29. If not ready, somebody else writes it.

Balazs to send an e-mail

0.6

• Feature freeze in CVS on September 1st 2005
• Aim at release by mid-September 2005
• TODO list in CVS, Balazs updates it regularly

Somebody called Jakob will evaluate the possibility to have complete data movemet in arclib and hence build ngcopy on arclib - not for 0.6
