regebroHuh? What does this mean:  exceptions.TypeError: Required specification must be a specification or class.15:39
regebroI try to adapt two interfaces...15:40
*** gimni|away is now known as gimni15:40
regebroBut when I use the implementation class instead of the interface it works.15:40

*** malthe has joined #zope3-dev15:57
*** J1m has joined #zope3-dev16:02
dobeebenji: ayt?16:05
dobeeregebro: i think you derived your interface from a non interface type16:06
regebrodobee: Well, not me in that case, it's not my interface. :)16:07
regebroWell, specifying the class instead works, so that's OK.16:07
dobeeah ok, it may also be an implementation class that derives from an interface class16:08
dobeei had this too16:08
regebroIt's funny that the specifying the class that implements the interface works, but specifying the interface doesn't work.16:08

regebroI love the component architecture.16:35
regebroOnce you get used to that way of thinking it's just so great.16:36
*** ignas has joined #zope3-dev16:39
mgedminregebro: pastebin the code that raises your error?16:40
mgedminI usually get it when I swap the order of arguments16:40
regebromgedmin: That didn't make a difference. The code is simply: adapts(ATEvent, IExecutable)16:41
regebrono sorry. THAT works.16:41
regebroadapts(IATEvent, IExecutable) doesn't.16:41
mgedminhow is IATEvent defined?16:41
regebroSo it's probably as dobee says, there is something that doesn't derives from Interface somewhere in the IATEvent hierarchy.16:42
regebroIt's a big interface hierarchy, i can't be bothered to check through it.16:42
mgedmintype(IATEvent) is what?16:42
regebromgedmin: <class 'Interface._InterfaceClass.Interface'>16:44
mgedminsounds reasonable16:44
regebroyeah, very strange.16:44

*** __mac__ has quit IRC17:19
TheuniZagy and I have hit a problem with the afterCommitHook (as reported in #137739)17:19
Theuniand we need some feedback on how to proceed.17:20
TheuniMy guess actually is that we should have (after|before)AbortHooks (symmetrical to (after|before)Commit)17:21
run|homeTheuni: i would say +1 to that17:21
Theuninote: you can implement those hooks using data managers already but they are a bit more complex than just a hook17:23

timteregebro: I got the same error not that long ago, but it was for IATFile, so I did like you and used the class instead17:29
regebrotimte: Yeah, there is something fishy with ATContentTypes, evidently.17:30
J1mTheuni, I hate the whole idea.17:32
J1mI have no great desire to dig in my heels.  But I have very little sympathy for this feature.17:32
J1mGiven that you have questions, this is not something that shoudl be done for 3.8.17:33
J1mTheuni, I like the observation about implementing these with data managers.17:33
J1mI like that a lot!17:33
J1mTheuni, ayt? I don't want to spew for nothing. :)17:34
*** LeoRochael has joined #zope3-dev17:34
LeoRochaelhi, when on a long running batch process, and trying to conserve memory, should I call root._p_jar.cacheGC() then root._p_jar.cacheMinimize()? or should I call it the other way around?17:35
LeoRochaelhmm, according to my question makes no sense at all...17:53

amit_amsrichter, I don't think I have the permission to checkin20:43

jodokJ1m: is there a way to pack zodb on a zeo using a different directory to store the temporary file? my zeo partition is running out of space and i don't have double space to pack it...21:28
*** regebro|away is now known as regebro21:28
J1mjodok, no.21:37
jodokJ1m: because it moves the file, right? i suspected that21:38
J1mIt renames the file.21:38
jodoko.k., too bad. thanks21:38
J1mIf you put the temporary file on another fs, it would have to copy that back and it would take too long.21:38

toutptwho what a strange bug i m on. My recipe install a parts directory. at uninstall it failed, but it try to remove /home/lost+found23:44
toutptreally strange23:44
J1mhehe, ya23:48
J1mis there something funky in .installed.cfg?23:48
*** greenman has quit IRC23:49
regebroYou know what I hate with Zope3? Especially with Grok in addition?23:53
regebroIt makes you feel really productive.23:53
regebroAnd then when you have to get back to Plone, coding feels like walking in Jello. :-/23:54
MrTopfHm, Zope3 so far hasn't made me very productive ;-)23:54
MrTopfI just keep wondering how something is supposed to work on every corner23:54
MrTopfmight be the same though when working with Plone as a Plone newbie23:55
regebroWell, true.23:55
MrTopfand honestly for me it's really a bit too overengineered23:55
*** mgedmin has joined #zope3-dev23:55
MrTopfor academic, whatever you want to call it23:55
MrTopfotoh I now checked out Django, Pylons and TG and there it's of course easier but you have to do a lot yourself23:56
regebroAlthough with Plone you wonder why it doesn't work.23:56
MrTopfso not really sure what's better23:56
regebroMuch is a matter of taste, of course.23:56
regebroWell, gotta go to bed. See y'all!23:56
*** regebro has left #zope3-dev23:56
MrTopfof course.. just wondering if one couldn't build something like a CMS on top of one of these frameworks23:56
MrTopfbut then again the question is at which point it might be as complex as Z3 or Plone23:57
MrTopfwell, cya ;-)23:57
