This is the meeting agenda/notes for the Meeting held on 2010-11-29.

Date and Time: 2010-11-29 20:00 UTC

Agenda

• Next Meeting
  • Jan 3rd
• Releases
  • 5.6.1 (starting today)
    • short 1-week turn around times
  • 5.5.1 (aim for Jan)
    • will start .pre1 a week or two after 5.6.1.pre1
  • 5.3.4 (post 5.5.1)
• Administrative
  • Policy reminder on changes from last meeting
  • Patch applying pain during a release?
    • cross release patches should be applied at the same time/revision, ideally
    • release on one branch breaks this (or delays applying stuff)
    • Results:
      1. Live with it
      2. use more branches (create a new branch just for the release, off the existing -patches branch)
    • Live with it
  • IETF Report
    • KSM is probably going to resurface; hopefully with code contributions
    • power management is doing a lot of work too
• Technical
  • Unit tests
    • Wes got trounced in the last month and didn't write the promised documentation
    • bvassche has been creating lots of tests
    • tabled until next time when Wes can get docs written
  • autoconf vs the world
    • still no takers on doing the work
  • stream lined/stripped-down
    • work under way to make a "read only" code set using an ifdefs (along with a script to actually remove it as well)
    • thinking about multi-pass compile for really-reduced code. Something like sample at bottom.
    • discussion results captured below
• Round Table
  • dts12: upcoming releases
  • Wes: most of the above discussion items
  • rstory: dtls testing

feature possibility thinking

Marking of features. Standard configure/make would always produce 1 for these ifdefs

// will only compile if needed by something else
NETSNMP_BEGIN_FEATURE(counter64)
... code ...
NETSNMP_END_FEATURE(counter64)

// something else says it's needed
NETSNMP_REQUIRE_FEATURE(counter64)

Adding an extra "make reduce" or something would turn them into real ifdefs

.

resulting conclusions

1. ifdefs over macros
   • but simple ifdefs. #ifdef NETSNMP_IMPLEMENTS_FEATURE
2. by default called from configure
   • but actually runs a sub-script for non-configure-possible platforms
3. new parallel to config_require
   • start with something new
   • maybe convert the MIB config_require later if possible
4. defaults to including all features
5. will be useful for reducing backwards-compatability code
