• Progress review
• How can we improve the extension location scenario?

• Memory consumption, can we also intern the strings at generation time?

Minutes

Round-table Progress

Dave

• Dave and DJ have been working on platform.xml support
• had some success
• still some problems
• needs more tests
• on track for M7

Susan

• wants to add code to better use the progress monitoring
• how do we want to handle the case where people try to install something while another install operation is already happening in the background
• on track for M7
• enable/disable sites might require some UI work

Darin

• new p2 target provisioning bundles are available in the next i-build
  • based on looking for capability
• added preference for target platforms
  • can use bundles.info
  • or can scan directory

Andrew O

• working on shared artifact repository

Tim W

• working on a few more patches

Scott

• would like to get some SSL changes into the build
• 2 new fragments - need to add those to the set of bundles that are included in the build
• new bundles might require equinox.security or only javax... Scott will confirm
• also working on some proxy-related code

Tim M

• working on SSL UI related code
• trust manager

Simon

• looking at some update site bugs
• will talk to Tim W in case work is related
• added #revert back in. will be in the next N-build
• curious about remaining work to be done to address startup regressions
• Pascal wants to look into the amount of time we spend going to the file system

Andrew N

• reviewed the publisher work that Jeff did
• looked at making the generator depend on the publisher
• that would take a few days to do if we wanted to take that route
• problems when PDE/UI calls p2... in PDE/Build we use statics to hang onto thing across calls but when PDE/UI does this the way that class loaders work it clears the static
• one fix might be to move the statics from the Ant task to the bundle
• or do a normal export and then a one-time generate on the result
• problem with multi-platform builds... rather than building once they build once per platform
• looking at PDE/Build reading a p2 target to get the state (some code is in the UI that we can look at)
• real answer is to be using FrameworkAdmin

Pascal

• working on patch support
• will also help with optionality in reconciler and some of the problems in shared install scenario
• need to come to a conclusion about this by the end of the week
• EPP currently uses the drop-ins functionality
• need to work with them to get proper packages

John

• discovery site - UM has support to extend the feature.xml to discover other features
• have released some code to handle this (from dropins and update site)
• doesn't handle the case where we use p2 to install the feature
• don't want to encode this functionality in the IU
• could have a new touchpoint that knows what to do
• have been thinking about site association
• currently we look at all sites when doing an update

DJ

• working on platform.xml code with Dave
• build stuff, update site stuff, etc

Extension Locations

• do we understand fully how people use extension locations?
• we allow people to add repos which are extension locations but we don't automatically add everything in the site
• we originally talked about an auto-install property on repositories
• if we improve our work-flow we should be ok
• we could auto-select everything when you first add a site so they just have to press Install

Multiple Configuration Folders

• we have people who run Eclipse with the -configuration command-line
• how were people initially creating this other configuration?
• configuration now means it has more things (p2 area, bundle info, etc)
• also people have problems where they are just deleting the configuration folder

Memory and Generation on Startup

• problems on startup when we are reconciling a lot of bundles
• after we generate, do we flush the IUs from memory?
• can we intern the string at generation time?

Build ID Problems

• be careful when getting the build id from people
• get it from the config.ini or the splash
• are issues w.r.t. it not getting updated correctly
