Planning

• Scoping and planning process
• Report content

Application Performance

• Overall
• Image processing [Russell]
• Detection [Tim]
• Association [K-T/Serge]
• NightMOPS [Tim/?]

Build system

• Current status [Ray/David]
• Shared libraries on MacOS
• g++ versions (3.4.6 vs. 4.0.1/TR1)
• Version management
  • trunk/svn/LOCAL vs. numbered
  • current vs. setup vs. restrictions
• Alternate ideas [Bill Baker]

MWI

Potential topics for lessons learned/discussion:

• Log vs. Trace [Ray]
• Exceptions (generic Runtime vs. app-specific) [Robyn]
• Policy vs. DataProperty
  • Policies and dictionaries and inclusion
• Persistence framework [K-T]
  • Writing Formatters (they are LSST-specific)
  • writeFits() methods vs. persistence
• Factory vs. constructor (use of SupportFactory, LsstDataConfigurator does nothing)
• JSON vs. PAF
• Common utilities should live somewhere else? (fw::getInt64FromAny(), fw::extractPolicyString(), dps.Utils.getDPValue(), dps.Utils.dataPropertyToDict(), ap::extractRequired(), ap::extractItemName(), ap::extractPolicyString(), ap::verifyPathName(), mwi::persistence::Storage::verifyPathName()) [K-T]

FW

• Application topics from appsDiscuss that deal with interface with middleware, not application innards [Russell]
