VladDracthanks to json :)00:57
VladDracthat is, the json implementation01:09
VladDraczope3 now supports amf, hurray :)01:09
yotajson server will be integrate in zope 3 in the future ?01:15
mnemocwhat is recommended for ajax on zope3?01:17
*** yota has quit IRC01:18
VladDracyota I don't know01:21
VladDracmnemoc: I know the z3ecm people are looking at ajax integration01:21

newpersis 256 mb or ram enough for running zope?05:28
newpersalso, is it better to go through apache?05:28
*** niemeyer has quit IRC05:29
*** MJ has quit IRC05:38
mnemocnewpers: imo if you don't need apache for anything else, use pound to do the rewrite05:47
newpersnow i have to decide if i want zope to be developed on my windows or linux machine.  windows machine has 1GB of RAM.  linux machine has 256MB.05:50
newpersi've never really developed on windows before05:50

VladDracis anyone actually *using* sqlos?14:16
VladDracit feels more like a proof of concept14:16
VladDraceven if I get it to work with 3.1 I wonder if it'll be of any real use14:16
*** jinty has joined #zope3-dev14:16
philiKONVladDrac, sidnei @ enfoldsystem is using it in production14:18
roymsrichter: my understanding is that any registered implentation of IAuthenticatorPlugin will show up in the adding view for a PAU - correct?14:18
VladDracphil hmm ok14:18
VladDracI wonder if he's using he same code as on codespeak :)14:18
philiKONroym, if you have a browser:addMenuItem defined for it...14:19

VladDracit works14:32
*** _projekt01 has joined #zope3-dev14:33
VladDracbut okay, I can't say I trust this code (in a Zope 3.1) environment to actually use it14:33
VladDracbesides it's really minimal, it doesn't even support relations14:33

philiKONroym, you want to adapt context to IPrincipalRoleManager to get local stuff, too15:53
philiKONdon't ever import any globals... in the component architecture, you look up stuff15:54

ChrisW_hey Fred :-)19:36
fdrakehey Chris19:36
ChrisW_me and Jens have a really nasty question for him relating to a tiny change he made for 2.8, which breaks some stuff in really obscure ways19:36
ChrisW_Jens has been doing the inten19:36
ChrisW_stare at screen thing for 2 days now19:36
ChrisW_it's to do with the application of class security info19:37
fdrakeah, yeah, that'll get him to have a really nasty question  :-)19:37
ChrisW_Jim made something work, which didn't used to work, but it's not clear that it should work19:37
fdrakethat happens sometimes19:37
ChrisW_so we're wondering if we should just make it no twork again19:37
ChrisW_but it's haaard19:37
ChrisW_Jens mailed to about it but had no reply from Jim19:38
fdrakeif its Zope 2, I'm not the one to ask  :-)19:38
ChrisW_where is he anywho?19:38
fdrakesomewhere in Europe; he doesn't clear his itinerary with me19:38
fdrakemaybe Germany?19:38
ChrisW_oh right, thought he'd a left there by now19:39
fdrakethe sprint was last week, right?19:39
ChrisW_oh well, if anyone sees him, please direct him towards Jens' question on zope-dev@zope.org19:39
faassenI think he's in France,19:44
faassenat Nuxeo.19:44
ChrisW_ah yes, the evil ZC/Nuxeo plot that ZEA are always talking about ;-)19:47

andresmgedmin, thanks.20:04
VladDracwhat's the correct way to "unwrap" a proxy?20:09
VladDracgrepping like a madman on the zopesource20:09
VladDracperhaps someone knows right away :)20:09
mgedminfrom import removeSecurityProxy20:09
*** tvon has joined #zope3-dev20:11
VladDracthat did th etrick20:12
VladDracmy returnvalues weren't properly serialized20:12
VladDracthey turned out to be Proxies in stead of the real values20:12
VladDracAMF integration is working very nicely now :)20:12
* mgedmin does not know what AMF means20:12
VladDracneither do I actually20:13
VladDracit's a lame protocol invented by Macromedia people to have their "RIA" toolkit "Flex" communicatie with servers20:13
VladDracit's like soap/xmlrpc/json20:13
mgedminFlash is evil20:13
VladDracand zope3 now can handle it :)20:13
VladDracit is20:14
*** tvon has quit IRC20:17

*** ChrisW_ has quit IRC20:19
andresmgedmin, sorry for asking that stupid: what is, when i want to set it in code, but not over the zmi? (as this is not writable)20:26

*** faassen has quit IRC20:31
mgedminandres, I do not understand your question20:36
andresI want to set the title attribute in code, but i dont want, that it can be changed in the zmi20:37
*** tekNico has left #zope3-dev20:37
andresbecause the title attribute is composed out of mulitple values out of a sql database.20:37
andresSo it absolutely makes no sense to be able to set them in zmi or any other form.20:38
andresbut if i dont have <require set_attribute="title" permission=whatever/> i cant set it in code.20:38
andresmgedmin, is it understandeable this way?20:42
mgedminI think I see20:47
mgedminin that case you may argue that there's a bug in the container view20:48
mgedmin"C:\Python24\Lib\site-packages\zope\app\container\browser\", line 169, _extractContentInfo20:48
mgedminif info['retitleable'] = canWrite(dc, 'title') raises ForbiddenAttributeError20:49
mgedminperhaps the container view ought to catch it and say that info['retitleable'] = False20:49
mgedminperhaps canWrite should do that (but I think not)20:49
*** mkerrin has joined #zope3-dev20:49
mgedminor perhaps there should be a special permission, zope.Never, you could specify in the permission declaration20:49
SteveAi used WEGSND for that ;-)20:51
SteveA"what even god should not do", a hang-over from zope220:51
SteveAand believe me, zope2 gives me a hangover20:51
SteveAi think the permissions system should have tokens 'public' and 'forbidden'20:52
SteveAso, zope.Public is deprecated, and becomes just 'public'20:52
SteveAand there's a 'forbidden' too, doing what you want zope.Never to do20:52
SteveAthese are special tokens, rather than permissions as such.20:52
*** alga has joined #zope3-dev20:55
andresmgedmin, thanks, so its ok, that i didnt understand that...20:58
andresi will try tomorow... But now i go home... worked long enough.21:00

tarekVladDrac: oki thanks23:57
VladDractarek but xmlrpc methods are essentially views, it shouldn't be to hard to list them23:57
VladDracpossibly using another view :)23:57
tarekyup, that what i thaught of23:57
* VladDrac 's been diving into the xmlrpc code last few days23:58
tarekoh good to know23:58
tarekare you comming at neckar ?23:58
VladDracdeveloping another rpc (amf), the implementation is very similar to xmlrpc23:58
tarekthe sprint23:58
VladDracprobbaly not :) When/where? (france?)23:59
tarekno germany, next week23:59
