philiKON_TresEquis is reviving zope.bobo?00:01
philiKON_J1m: re egg day: theuni, uwe and I were discussing a cleanup sprint at europython00:03
philiKON_J1m: to be scheduled at the end fo september00:03
philiKON_cleanup as in dependency cleanup00:03
TresEquisphiliKON_: I just tried making an egg of it, which led me to the sulphurous hairball that is
fsufitchanybody here familiar with i18n?00:05
fsufitchi need some help with it00:05
lisppaste6fsufitch pasted "Traceback" at

fsufitchk good :)00:06
Lumieresrichter: see traceback pasted above ;)00:06
*** greenman has quit IRC00:07
*** jodok_ has joined #zope3-dev00:07
srichterI have no idea what this error is00:07
srichterit will require some serious debugging00:07
srichterfirst you have to find the location in the page template where this happens00:07
fsufitchi did00:07

Lumierethat isn't it, it's a piece generated from a zcml00:08
srichterdid you specify an i18n domain in the scope of the call?00:08
*** jsadjohnson has quit IRC00:08
fsufitchalthough i barely have a notion of what u mean...00:09
fsufitchthis was in an ftest00:09
*** RaFromBRC|lunch is now known as RaFromBRC00:09
fsufitchwhere i just did getLink("Import Competencies").click()00:09
srichterwell, where in the template is the "i18n:domain" decalration (btw, I am just guessing that this might be the problem)00:10
fsufitchin the <html>00:10
lisppaste6Lumiere annotated #45180 with "page zcml" at
srichtermh, then I have no idea00:11
srichteryou have to use the debugger to see what's going on00:12
Lumierek -> eldar ;)00:12

J1mphiliKON_, that sounds good.00:44
J1mTresEquis, I thought I hooked it up w wsgi, but I don't remember for sure.00:45
TresEquisI get the feeling that there is about five times too much machinery there as needed00:45
J1mThe dance to set this up with or is a mess.00:45
TresEquisfor instance, why is the publication not looked up as an adapter to the request00:45
J1mCould be.00:46
philiKON_publication and request are usually created together00:46
*** Ariel_Calzada has joined #zope3-dev00:46
philiKON_at least that's how it is in plain zope 300:46
philiKON_why should i know, i didn't write that :)00:47
TresEquisit looks as though it tries to reuse the publication *instance* across requests, which is just silly00:47
TresEquisif IPublication were and adapter interface00:47
TresEquisthen all its API would lose the 'request' argument00:47
J1mI don't really remember the details and can't look atm.00:47
TresEquisand the publisher would just adapt the request00:47
J1mI'm sure major improvements could be made.00:47
philiKON_that much is certain00:47
TresEquiswe could move all the silly traversal logic out of the request, too00:47
*** philiKON_ is now known as philiKON00:48
TresEquissince that is inherently a policy of the publication object00:48
philiKONyes yes yes00:48
TresEquisso object publication would consist of:00:48
TresEquis1. adapt request to IPublication00:48
* philiKON looks into his magic ball and sees a branch of zope.publisher coming up00:48
*** eldar has quit IRC00:49
TresEquis2. call the IPublication methods in template fashion until the publication says stop00:49
TresEquiswe could then throw out all the 'requestpublicationfactory' nonsense00:49
TresEquiswhich I can't figure out how to configure now00:50
J1mI doubt we need to use adaptation to get the publication.00:50
philiKONTresEquis: it's nasty00:50
philiKONTresEquis: grok does it00:50
J1mUse Python luke.00:50
J1mand wsgi00:50
J1mand paste00:50
philiKONbut something needs to create the publication00:50
TresEquisthe publication object could just turn into the WSGI application00:50
J1mI though philiKON  cleaned all this up w his paste work. :)00:50
philiKONand making the publication an adapter of request seems quite good00:50
philiKONJ1m:  i merely provided tiny shims over what's there already ;)00:51
philiKONTresEquis: almost00:51
J1mI think the application setup code could do it.00:51
philiKONTresEquis: there's which ends up creating request + publication00:51
J1mIt's not like a single application is going to have more than one.00:51
TresEquisJ1m:  adaptation might be needed to allow DAV traversal to differ from "normal" traversal00:51
philiKONdifferent kinds of requests have different kinds of publications00:52
philiKONat least right now00:52
J1mbut I really don't have time for an on-line design session though. :)00:52
philiKONmay not be a good idea00:52

*** ChrisW has joined #zope3-dev12:46
ChrisWmornin' all, where do I find the actual provideAdapter call that results from a zcml <adapter> directive?12:46
ChrisWI'm specifically interested in what turns the * into whatever it gets turned into...12:46
wiggyit gets turned into zope.interface.Interface12:47
wiggyI'm guessing zope.component12:47
ChrisWsee, I reckon it gets turned into None12:47
wiggyafaik it doesn't12:48
ChrisWwell exactly, hence trying to find the code ;-)12:48
wiggyzcml doesn't directly result in a provideAdapter call, there is delayed init involved12:48
ChrisWyeah, I'd imagine an action gets created during zcml parsing which later results in the provideAdapter call12:49
ChrisWhowever, the action contains all the parameters12:49
ChrisWso I suspect the parsing is done before then12:49
wiggyit is immediately parsed12:49
ChrisWyeah, and I reckon it's the parsin that turns the * into something12:50
ChrisWI guess that's the code I'm looking for12:50
ChrisWit's not in zope.component12:50
ChrisWI suspect it's in, I'm just trying to figure out where12:50
bigkevmcdmaybe put an error in and look at the traceback?12:54
projekt01ChrisW, * represents None12:55
projekt01This is done in zope.configuration.fields.GlobalObject / fromUnicode12:56
ChrisWprojekt01: thanks, who are you?12:56
projekt01The field converts the * to None and the adapter registry uses None as discriminator12:56
projekt01ChriW, Roger Ineichen12:57
ChrisWaha, thought I rememberedthe projekt01 ;-) Thanks Roger!12:57
ChrisWI think I may have found some weirdness with adapter looks preference, just playing around to see if I can reproduce...13:00

fdrakeprojekt01: Probably not.  ;-)  What I want is to report a bug in z3c.configurator.21:32
projekt01Ah, I don't know what is the state of the art for report a bug right now. Probably launchpad since the community is not able to develope a own bugtracker.21:34
projekt01fdrake, what is the issue?21:35
fdrakePerhaps so.21:35
projekt01You can tell me what is the issue, I'll fix that.21:36
*** tarek has quit IRC21:36
fdrakeThe requiredPlugins() function can enter an infinite recursion because it doesn't keep track of what it's looking at in each iteration of _add().21:36
fdrakeTaking note of the items as it enters _add() avoids that.21:36
*** richardkan has quit IRC21:37
projekt01Did you fix this allready?21:37
fdrakeI have a patch, but it's a hack; I've only used that package a very little, and probably don't understand the full requirements.21:38
fdrakeI'll get the patch I made...21:38
