My Efforts

• Effort/Revise OOo Multi-Threading
  • Tasks
    • cppu - remove the cppu::ClearableEnvGuard - done
    • verify that cppu::Shield is indeed needed and works as expected - done, it is needed!
    • review documentation, place tests and testers
    • rename Environment.pReserved -> pEnterable
    • do threading tests - with component, with the office
    • convert rest of office services to be thread unsafe - in progress
    • convert dtrans to thread affine?
    • Rename Threading Model impl to Threading Framework?
    • See if I can optimize the "identity mapping" somehow.
  • Possible order of integration
    • done - SRC680_m191: some clean ups - krmisc
    • done - SRC680_m196: Binary Uno identity mapping - bunoidmap - depends: krmisc
    • done - SRC680_m212: Binary Uno extended threading model - bunoexttm - depends: bunoidmap
    • in progress : VCL thread-transparency 1 - vclthreadtransparency1 - depends: bunoexttm
      • fix thread-affinity
      • DDE
      • Drag&Drop
      • Clipboard
    • open : Binary Uno new threading architecture - bunonewta - depends: bunoexttm
    • done - SRC680_m195: async dialogs - asyncdialogs
    • in progress : async dialogs 2 - asyncdialogs2 - depends: asyncdialogs
    • open : VCL thread-transparency 2 - vclthreadtransparency2 - depends: asyncdialogs2, vclthreadtransparency1
      • remove the Solar Mutex
    • open : new OOo threading architecture - ooonewta - depends: bunoexttm, vclthreadtransparency2
• Move Uno stuff into the Uno Wiki. See Uno/Effort/Migrate Documentation.
  • Update udk.openoffice.org to reflect latest wiki changes.
• Do a source code inventory:
  • Analysis/Source Code Inventory
