Current total open defects: 428
(last sprint: 408)

Past Sprint Review

Research tickets appear to take both more calendar-time and personnel hours than anticipated.

shared mem design: needs a bit more fundamental design that is not really suitable for a simple email, working on wiki page

Jinmei: I think we can close #2777

Shane: What I'd like to do is basically have a proposal for the architecture and design for the system by the end of the month (march). So obviously we need some more work.

This (research) type of work does not appear to fit snugly in a scrum setting, but we do need some form of tickets so that we don't ignore the work completely. This type of tickets may not be the ideal solution but we'll probably need to do something similar in the coming sprints.

We could schedule some time in next week's meeting to make final decisions, but this should not be a brain-storming session (use list for that if you have something)

Past Sprint Goals

  • Resolver work?
  • Shared memory auth design?
  • Some more work towards msgq
  • Some final(?) work on rdata parsing for loadzone-ng

all points have been worked on, but these aren't really goals with deliverables...

Estimate/ticket Discussion

#2753 (error building BIND 10 1.0.0-rc on Debian 6)

Ranges from 1 to 8, I think because most of us don't have an idea what
is causing this at the moment...


#2755 (the use of "list" structures for configuration
considered harmful)

This probably needs some discussion; i tend to agree in general, but
also see the ticket comments


#2788 (bind 10 binaries should be stripped at install time)

This may have consensus already (it's looking to go the wontfix direction)


#2819 (row 55) (configuration file path relative to a BIND 10 "home
directory")

While it's about configuration (and hence one is inclined to think
pile it on the ng stack); this is slightly different, as it's about
how 'path' values are *used*. Unless part of the -ng is to introduce a
'path' type (as opposed to a string), this needs to be handled every
place where a path config is used.


#2820 (row 56) (system/platform independent BIND 10 configuration)

It seems unclear what we should do here.

Seems mostly about portability-related things rather than run-time environment. But it's quite abstract what kind of parameters are meant here.

set to 'needinfo'? dhcp task? *can* we get around it?


#2822 (remove dependecies to OpenSSL, use Botan instead)

(discussion on-list ongoing)

Goals

Shane wants resolver design in next 1.5 sprint, so that will have to be the main goal.

  • Resolver design
    • create receptionist metaticket? (ticket to create the tickets)
    • make the rest of the design tickets more concrete
  • Shared-mem design

Do we need more tickets than the current 'research' set? Shane will go through what we think the design will look like and pick outstanding questions out of that.

take 24 points; one of them is untaken, so reserve 16 points for 'research work to be filled in'

3 for receptionist ticketcreationticket

carry on existing 2778

Time off

Mukund: PTO on March 8 and 15. Perhaps off sometime in week of March 18 on BTR -R.

IETF next week, anyone going? no.

60-70?

Tickets

carry on existing?

have discussion on 2668 and pull it out for now

raise priority of 2624

2737, leave as is?

need to check if sprint master page is up to date and clear
