[3:10pm] PeterThoeny: ah
[3:10pm] PeterThoeny: shall we start?
[3:10pm] PeterThoeny: i have limited time today
[3:10pm] PeterThoeny: http://twiki.org/cgi-bin/view/Codev/KampalaReleaseMeeting2016x02x04

[3:11pm] PeterThoeny: 3. Review Urgent and Not So Urgent Bugs
[3:11pm] PeterThoeny: 4. Miscellaneous
[3:11pm] PeterThoeny: ---++ 1. Feature Requests for Kampala Release
[3:11pm] PeterThoeny: http://twiki.org/cgi-bin/view/Codev/WebChanges
[3:12pm] PeterThoeny: twiki.org/cgi-bin/view/Codev/TWikiFuncGetDebugFilePath - by hideyo-san
[3:12pm] PeterThoeny: i have seen checkins
[3:12pm] PeterThoeny: are we all good here?
[3:13pm] HideyoImazu: I believe s
[3:13pm] HideyoImazu: so
[3:13pm] PeterThoeny: status?
[3:13pm] HideyoImazu: it's done
[3:13pm] PeterThoeny: cool
[3:14pm] PeterThoeny: i think that's it for features
[3:14pm] PeterThoeny: any feature you'd like to discuss? also brainstorming
[3:14pm] HideyoImazu: no
[3:15pm] PeterThoeny: ---+ 2. Extensions
[3:15pm] PeterThoeny: http://twiki.org/cgi-bin/view/Plugins/WebChanges
[3:15pm] PeterThoeny: DataTablePlugin - by hideyo-san
[3:16pm] PeterThoeny: updated
[3:16pm] HideyoImazu: minor update
[3:16pm] PeterThoeny: http://twiki.org/cgi-bin/view/Plugins/CasLoginContrib - by LucasMaciuga
[3:16pm] PeterThoeny: updated directly the tarballs
[3:16pm] PeterThoeny: e.g. not updated in svn
[3:16pm] PeterThoeny: wondering if we should sync back to svn
[3:17pm] HideyoImazu: did you have a chance to talk to him?
[3:17pm] HaraldJoerg: It's flagged "no" for DevelopedInSvn, but syncing wouldn't harm
[3:18pm] HideyoImazu: I wonder if it's possible to have him do that
[3:18pm] HaraldJoerg: Maybe he has no commit rights?
[3:18pm] PeterThoeny: this contrib is already in svn
[3:18pm] HideyoImazu: or he just doesn't know the process?
[3:19pm] PeterThoeny: maybe he has no commit rights, maybe he is not intersted in using svn
[3:19pm] PeterThoeny: let me reach out to him to invite to update to svn
[3:19pm] PeterThoeny: yes, if he is intersted and not in dev list, he can follow the process and request svn access
[3:20pm] PeterThoeny: i'll check
[3:20pm] HaraldJoerg: Without SVN syncing, "PleaseFeelFreToModify" is somewhat fragile
[3:20pm] PeterThoeny: http://twiki.org/cgi-bin/view/Plugins/CgiContribDev - comment by harald
[3:20pm] PeterThoeny: i have read the comment
[3:20pm] PeterThoeny: yes, good to update the known issues
[3:20pm] HaraldJoerg: Ah, yes, that's what hit me hard when I tried to work on the taint issue with Debian Jessie
[3:21pm] HaraldJoerg: Only it was well after midnight when I wrote that comment, so I decided to postpone it
[3:21pm] PeterThoeny: best to create a bug item (if not done already), and point to the bug item in the known issues
[3:21pm] HaraldJoerg: Yes, that's what I plan to do
[3:21pm] PeterThoeny: thanks!
[3:22pm] HaraldJoerg: The bug can be flagged "no action", because 6.0.2 does the trick, but we should have a clear 
reference quoting the symptom
[3:22pm] PeterThoeny: i think it would be also good to have an attention note in the CgiContrib docs pointing out the issue
[3:22pm] PeterThoeny: yes
[3:22pm] HaraldJoerg: Ah, ok, good point
[3:23pm] PeterThoeny: harald or hideyo-san, who wants to do the contrib doc update?
[3:23pm] HaraldJoerg: I can do that
[3:24pm] PeterThoeny: ok
[3:24pm] PeterThoeny: http://twiki.org/cgi-bin/view/Plugins/PloticusPlugin - bu HideyoImazu-san
[3:24pm] PeterThoeny: "by"
[3:24pm] PeterThoeny: so these are the debug entries? anything else?
[3:25pm] HideyoImazu: bug fixes
[3:25pm] HideyoImazu: code cleanup
[3:25pm] HideyoImazu: doc cleanup
[3:25pm] PeterThoeny: ok
[3:25pm] PeterThoeny: anything else on extensions?
[3:26pm] HaraldJoerg: No
[3:26pm] PeterThoeny: fyi, i might contribute a new plugin if the client approves the project
[3:27pm] HideyoImazu: cool
[3:27pm] PeterThoeny: they have knowledge base pages and want an easy way to restrict access on selected kb topics to a 
specific group
[3:28pm] PeterThoeny: so they want to button to "restrict access" if open, or a button "remove restriction" if restricted
[3:28pm] PeterThoeny: right now the manyally change the Set ALLOWTOPICVIEW in the topic, which is error prone
[3:28pm] HaraldJoerg: Sort of a clickable * Set ALLOWTOPICVIEW = SpecificGroup?
[3:28pm] PeterThoeny: yes
[3:29pm] PeterThoeny: with settings stored as topic preferences in meta data
[3:29pm] HideyoImazu: I would implement with DYNAMIC_ACCESS_CONTROL = on
[3:29pm] PeterThoeny: ah, is that the stuff you did in trunk?
[3:30pm] HideyoImazu: yes
[3:30pm] HideyoImazu: with that, variables in ALLOW* and DENY* are evaluated
[3:31pm] PeterThoeny: how would you configure for the described scenario?
[3:31pm] HideyoImazu: for example ...
[3:32pm] PeterThoeny: ah, Set ALLOWTOPICVIEW = %FORMFIELD{ "Access control" topic="%BASETOPIC%" }%
[3:32pm] PeterThoeny: then have that form field set to a select with empty of name of group
[3:33pm] PeterThoeny: which would allow also a button to toggle the form field
[3:33pm] HideyoImazu: * Set ALLOWWEBVIEW = %IF{"'%FORMFIELD{"Access Control"}%' = 'on'" then="SomeGroup"}%
[3:33pm] PeterThoeny: ah, yes, even more simple
[3:33pm] PeterThoeny: have you done performance tests?
[3:34pm] HideyoImazu: not really. but I've never had performance problems
[3:34pm] PeterThoeny: what if there are several hundred entries in a query?
[3:34pm] PeterThoeny: or several thousand?
[3:35pm] HideyoImazu: it may can be slow
[3:35pm] HideyoImazu: but the value is cached during a session
[3:36pm] PeterThoeny: cached for all topics?
[3:36pm] HideyoImazu: so, at least, the same topic evaluate its accessibility only once
[3:36pm] HideyoImazu: that's right
[3:36pm] PeterThoeny: ah, so running report the first time is slower, after that faster
[3:36pm] PeterThoeny: but that's in a fastcgi env
[3:37pm] PeterThoeny: for regular cgi there is no caching between pageloads
[3:37pm] HideyoImazu: i'm talking about within a single session
[3:37pm] HideyoImazu: with %SEARCH{...}%, you may access many pages
[3:37pm] HideyoImazu: and each page's accessibility is checked
[3:38pm] PeterThoeny: and cached in user session?
[3:38pm] HideyoImazu: no
[3:38pm] HideyoImazu: cached in the TWiki object
[3:39pm] PeterThoeny: ah, yes, not user specific
[3:39pm] PeterThoeny: but in fastcgi, is the caching across page loads?
[3:40pm] HideyoImazu: no
[3:40pm] PeterThoeny: ok
[3:40pm] HideyoImazu: DYNAMIC_ACCESS_CONTROL is still regarded experimental
[3:40pm] PeterThoeny: that is again a case for mongodb 
[3:40pm] HideyoImazu: it can be tricky and difficult to devug
[3:40pm] PeterThoeny: do you remember how many files you touched for this feature? wondering how involved it is to 
patch a twiki-6.0
[3:40pm] HideyoImazu: but worth playing around
[3:41pm] HideyoImazu: it's only in TWiki/Access.pm
[3:41pm] HideyoImazu: nowhere else
[3:41pm] PeterThoeny: ah, so easy to patch
[3:41pm] PeterThoeny: i'll check it out
[3:41pm] PeterThoeny: ---++ 3. Review Urgent and Not So Urgent Bugs
[3:42pm] PeterThoeny: http://develop.twiki.org/~twiki/cgi-bin/view/Bugs/WebChanges
[3:42pm] PeterThoeny: ah, many changes, but just toggle from waiting for release to closed
[3:42pm] HaraldJoerg: Well, TWiki:Support/SID-02145 is not yet filed as a bug, but should be documented in Bugs
[3:43pm] HaraldJoerg: http://twiki.org/cgi-bin/view/Support/SID-02145
[3:43pm] PeterThoeny: ah
[3:44pm] PeterThoeny: could you do that HaraldJoerg?
[3:44pm] PeterThoeny: otherwise no bug items we did not already cover
[3:44pm] HaraldJoerg: I'm on it and already spent a few hours debugging...
[3:44pm] PeterThoeny: thank you
[3:45pm] PeterThoeny: anything else on bugs?
[3:45pm] HaraldJoerg: Nope
[3:45pm] PeterThoeny: ---++ 4. Miscellaneous
[3:46pm] PeterThoeny: in a january release meeting i mentioned a to be released FlotChartsContrib
[3:46pm] PeterThoeny: that project did not pan out with the client
[3:46pm] PeterThoeny: e.g. currently on hold
[3:47pm] PeterThoeny: anything else?
[3:47pm] HideyoImazu: no
[3:47pm] HaraldJoerg: Not for today
[3:47pm] PeterThoeny: ok, let's close the meeting
[3:47pm] PeterThoeny: i'll post the minutes and logs as usual
