Subject Re: IRC chat summary

One comment: I do hope that once we hit feature freeze that we can spend 
some time stabilizing the release, having a "bug-fix fest".  We don't 
*have* to immediately go to GA release as soon as feature freeze is 
complete.  Maybe we could in the past, when we had fewer bugs and fewer 
contributions, but now perhaps we need a longer stabilization period. 
Maybe a release criteria could include a reduction in bugs by a certain

it all fits into the Junit framework.

sure if they are at this point, we'll see

regular bug reviews?

right now.

going in and the bugs that customers are hitting.  I am about to file one that the client
connection state for pooled connections is not getting reset properly  for isolation, autocommit
or  holdability.  Manjula  hit a serious  issue blocking system tests.  Perhaps is is just
a cycle but I  have customer cases coming in like a...

had asked how other projects handle bug triage.

it out -- and fixing it

it - httpd comes to mind

> (19:49:08) marsden: Yes. I had considered. "Can you break Derby?" contest on the QA side
and "Can you fix Derby?" contest on the fixing side.

in it..
> (19:51:22) marsden: I like bug fixer of the month, but maybe make it more generic to
be more of a "quality star" there are so many testing tasks that need to be done.

> (19:52:08) daghw: SO, yes, giving it attention is necessary.

> (19:52:57) daghw: We should all have those anyway .!!
> (19:53:04) jta: :-)
> (19:53:21) jta: how about a special t-shirt -- "I fixed a bug and all I got was this
damn shirt"
> (19:53:50) jta: oops, maybe not such a good byeline

many bugs?
> (19:55:58) daghw: i didnt know... where?

> (19:56:21) daghw: data bases are complex products... is one answer!
> (19:56:23) jta: people equate a jira number with "bug"  so DERBY-1023 means Derby has
had 1023 bugs so far
> (19:56:37) jta: in fact, Jira issues include features and subtasks
> (19:56:54) daghw: Well, MS KB numbers in the hundred thousands..!
> (19:57:01) marsden: There are 155 outstanding cod ebugs
> (19:57:04) daghw: but it coul dbe a perception problem
> (19:58:01) marsden: But one thing is client. It is a brand new thing as of 10.1. It needs
more testing  and  work.
> (19:58:09) jta: so back to the original question ... how do we entice people to fix bugs?
> (19:58:44) daghw: agreed. the client code has a way to go
> (19:59:40) jta: is fixing client code a good entrypoint for potential contributors?
> (20:00:13) jta: --I think Kathey has done some good work trying to highlight what might
be easy to fix
> (20:00:17) daghw: depends.... if error envolves communication issues, answer is probably
> (20:00:32) daghw: (DRDA is intimidating at first)
> (20:00:51) marsden: I think that the newcomer tasks are a good way to identify issues
for newcomers.
> (20:01:07) daghw: yes i like that!
> (20:01:21) jta: could a pointer to be added to http://wiki.apache.org/db-derby/ForNewDevelopers
> (20:01:23) marsden: But it is interesting that most everyone that seems  to want to contribute
wants to pick up some new feature.
> (20:01:35) marsden: Is it not there?
> (20:01:40) jta: I'm looking ....
> (20:02:23) marsden: I shouldn't say that.  Some folks have come in fixing a lot of bugs
like Bryan.
> (20:02:36) jta: oh I see it -- the "First Code Changes" section points to the Jira "Newcomer"
> (20:02:41) daghw: Some people's "itches" are not ncessarily their own at all times ;)
> (20:03:02) daghw: Bryan has been a great example
> (20:03:07) marsden: Also some bug fixes that have been   contributed have been ignored
by committers
> (20:03:27) marsden: DERBY-974
> (20:03:27) daghw: i suspect he has more latitude than some though, as far as priorities.
> (20:04:31) marsden: Yes I guess that is the key point a lot might be related to what
the paid volunteers are paid to work on.
> (20:04:34) jta: re DERBY-974, it looks like Deepa commented on it yesterday
> (20:04:51) daghw: in deed!
> (20:05:07) marsden: Yes. I asked her to. It has been sitting since Feb 13.
> (20:05:28) jta: Satheesh commented on it on Feb 14, and there it sat
> (20:05:41) daghw: if a bug gets forgotten, i think prompting the list again is ok
> (20:05:48) jta: it's definitely ok
> (20:05:55) marsden: There are 18 available patches.
> (20:06:09) jta: but new contributors might need to be encouraged to prompt the list "don't
be shy! your work is valuable!"
> (20:06:27) marsden: And so in addition to bug review we need  outstanding patch review.
> (20:06:46) daghw: yes, i sometimes worry newcomers can be put off 
> (20:07:21) marsden: Dag, would you mind summarizing this conversation and posting to
the list?
