Past Sprint Review

jelte: I suspect that due to people being away, we didn't have anyone to do reviews at a number of times. Also, a number of tickets are mergable but are waiting for other tickets to be finished (perhaps we do need a separate state for that).

jinmei: there were several things that were special for this sprint. Not sure if it's just about the special situation of this sprint or that we need to think about something in general. Apart from the holidays we have statistics tickets which by their nature make the review queue longer. One thing I noticed is that we probably need to recall that we should generally prioritize review tickets. Otherwise the review queue is getting longer and longer.

jinmei: also, there is one review ticket which has been open for quite a while; #2136. And assigned review work should have an even higher priority than other tasks.

Mukund: in this case, 2136 was reviewed and assigned back to the implementer, then I picked up 2165 and 2166 and that took quite some time, and I couldn't get back to 2136

Jelte: so 2165 was heavily underestimated?

jinmei: yes we cannot prevent that from happening sometimes. But we should probably take some action on the suspended review thing

jinmei: rather than leaving it open for a long time we should take some action and we should resolve it in the daily call probably

jinmei: one other thing, #2160 has been taken but there was no progress. If this happens it should probably be released so someone can take it over.

Past Sprint Goals

  • Further work on Scalability


  • Final breakdown of background loading


  • Statistics

some done, not all of them



  • Activate the new datasource

(what's left?) some cleanup tasks, maybe update some of the python programs (some of them use old config)

  • Do performance test?

need to update the new configurations, then it can just be run

  • Asynchronous zone loading

how many points? long queue atm business trip for jinmei

60-ish again?

jinmei: i'd like to get estimates for a couple of tickets, which are necessary for the in-mem scalability tasks

2218 2219


Should we carry current untaken tickets over?

2180: jinmei: not entirely clear what is needed here vorner: when bind10 starts for the first time, it creates the database, but if you change config and make a typo, it silently creates an empty new db there jelte: so only log a warning if the db doesn't exist? vorner: and then still create it jeremy: but if it points to a different file, there might still be a problem (if it's a valid file, but is the wrong one), so perhaps also check timestamp or number of zones or something vorner: does that happen a lot? jinmei: it's not about whether it's empty or not, but whether it's created? vorner: yes

jinmei: it already logs at info level vorner: so we just need to change it to warning jinmei: and probably add the filename


current tickets left new amount to 16 points
(this includes #2098 and #2108)

add statistics work:
(a third of the originally estimated points would give us 7 in total for these)

open work for meta-ticket #2101:

2216   update query_bench so it will use the new data source  config                  Next-Sprint-Proposed  defect        b10-auth                    3

There does not appear to be enough time to start with the zoneloading just yet; we'll see in one week if we can get it in after all. (the total is about 60 points of work)
