Report HUMAVIPS code camp (also make notes for Stefan)

  • Aldebaran
    • Develops new open middleware
    • Made a tool for building binary distributions
    • Nao Robot
      • Improved CPU
        • Increased performance (e.g. video streaming)
      • Will be open sourced within a few weeks
  • High-level overview of projects currently missing
    • Catalogue can solve this (at least for CITEC projects)
    • Currently in beta
    • What about partners?
      • Partners can use the catalogue
      • CI servers of partners could be integrated
  • Experiences
    • RSB mostly OK
    • RST unclear
    • Easy-to-use Matlab interface would be useful

RST Policies and (Re-)Organization

  • Sandbox Area
    • Add separate directories per user or projects in Beta
    • Use different name for "beta", e.g. "sandbox"
    • Communicate that changes in "beta" are allowed and welcome
    • Promotion requests as redmine issues?!?
    • Use separate libraries / redmine projects for beta part?
  • Install type system in prefix
  • External monitoring needed and welcome
  • Connect type system to catalogue
  • How to decompose domain types in protocol buffer types?
    • Can language level considerations give guidance? (e.g. sending a 3DPoint as part of another object to a generic 3DPoint component)
  • Consider API/ABI breaks if RST types change (what cases exist?)
  • Consider naming scheme for protofiles?
  • RPC service to retrieve IDL information from running components via libRST?
    • One RPC service per process?
  • Decisions:
    • So far, we will collect the datatypes in the RST repository
    • Add installation target for proto files to RST library makefiles to have the IDL defs in $prefix
    • Or, if possible add introspection support for RST such that converters can report on their used IDLs
    • Use $prefix/share/RST for logger to retrieve IDL specifications

System-level Introspection

  • Urgently needed: Informer per Participant about participant state
    • Provide client-API in separate library + unix tool?
  • Requirements (Motivation: Debugging)
    • Presence / state information
    • Type introspection
    • Application-level logging (and runtime configuration)

Default Connector Policy

  • Proposal
    • Enable only in-process transport
    • Yes, accepted.
