Minutes from face to face meeting @ FU Berlin on September 27, 2013
Local participants: Lotte Steenbrink, Christian Mehlis, Oleg Hahm, Ludwig Ortmann Skype participants: Thomas Eichinger, Martin Landsmann Minute taker: Ludwig
1.) Message API Problems 2.) Merging Policy 3.) Features for the next release 4.) C++ integration 5.) Makefiles Windows compatibility 6.) Network stack memory optimization
- invalid (internal problems in Christian's application)
- reminder: anyone with commit rights should merge as soon as enough people have acknowledged the pull request and the pull request has been open for reviewing $long enough
- trivial changes (like a new header include) can be merged immediately after the first ACK
- network stack optimization
- POSIX features
- time.h
- pthread.h
- semaphore.h
- Martin Lenders looks at the network part, Christian at the rest
- Martin Landsmann checks what is needed for libcppa
- basic support for Cortex A9
- destiny fixes
- CoAP
- CCN lite
- currently issues with printf and float (e.g. for the sht-11 on MSB-A2)
- encapsulate with "extern C", pull request follows
- find yet not declared functions and add them to the header
- try to avoid ifdefs
- split up the pull request (wherever possible)
- the according pull request needs to be updated and should be merged (no further objections)
-
currently every abstraction layer holds its own buffer
-
the upper layers should share one buffer, possibly using Stephan Zeisbergs memory manager
-
the lower layers (driver and transceiver module) should use one buffer together
-
possible real-time improvement: driver just informs the transceiver module, which fetches the packet from the radio
-
additional: check defined stack sizes and try to minimize them
Next meeting: Since the next release is envisioned for November (due to CoAP plugtest (20.11. and SAFEST demo (25.11)) -> 28.10 - 1.11., Doodle follows
