| WebMaven | srichter: AYT? | 08:40 |
| CSWookie | WebMaven: Do you know how to adapters out of the registry without knowing the kinds of things they adapt? | 08:45 |
| CSWookie | WebMaven: I'm trying to spelunk my adapter registery to better understand what's going on. | 08:45 |
| WebMaven | CSWookie: I don't think I understand the question. | 08:46 |
| WebMaven | you want a list of all adapters? | 08:46 |
| CSWookie | WebMaven: For example, I know that my AddForm class implements IAdding, and I'm pretty sure thaat in order to get it out of the registry, I'd need a request of some sort. I want to be able to say, "Hey aapter registry, give me all the registered adapters, and let me look at them. | 08:47 |
| CSWookie | WebMaven: And that way I'll be able to figure the rest of what's registered. | 08:47 |
| CSWookie | Basically, the Adapter and Utility registries are sort of black magic for me, and I want to better know how they work. | 08:48 |
| WebMaven | Umm... I guess you could ask for everything that adapts None... | 08:48 |
| WebMaven | I think that gets you everything, but I'm not sure. | 08:48 |
| CSWookie | I think maybe I'll just hang it up for the night, and ask at work tomorrow. It's well meyond a sane man's bed time. | 08:51 |

| WebMaven | CSWookie: good night, then. | 09:05 |
| srichter | WebMaven: here | 09:06 |
| WebMaven | Ah, good. | 09:06 |
| WebMaven | I'm having trouble finding an example of a success_handler | 09:06 |
| srichter | in formlib? | 09:07 |
| WebMaven | Yes. | 09:07 |
| srichter | @form.action(_('Action')) | 09:07 |
| srichter | def handle_action(self, action, data): | 09:07 |
| srichter | ... | 09:07 |
| srichter | handle_action() is the success handler | 09:07 |
| WebMaven | Umm | 09:07 |
| WebMaven | OK, I guess I was confused. I found this in form.py: | 09:08 |
| WebMaven | def success(self, data): | 09:08 |
| WebMaven | if self.success_handler is not None: | 09:08 |
| WebMaven | return self.success_handler(self.form, self, data) | 09:08 |
| WebMaven | So it looked like I needed to make an optional method named success_handler | 09:09 |
| WebMaven | OK, so, if that's where I'm supposed to put the code, I'm not sure why this doesn't work: | 09:10 |
| WebMaven | @form.action(_(u"Apply Changes")) | 09:10 |
| WebMaven | def handle_edit_view_action(self, action, data): | 09:10 |
| WebMaven | self.default_actions['form.actions.apply'].success(data) | 09:10 |
| WebMaven | xmlerror = validateXML(self.context.page_xml) | 09:10 |
| WebMaven | self.context.page_isvalid, self.context.page_error = xmlerror | 09:10 |
| WebMaven | self.request.response.redirect(self.nextURL()) | 09:10 |
| WebMaven | I get this error: | 09:11 |
| WebMaven | ForbiddenAttribute: ('page_isvalid', <rogue.courses.page.Page object at 0xb6b4bbac>) | 09:11 |
| srichter | looks like you are missing a security declaration for the page_isvalid attribute | 09:12 |
| WebMaven | Yeah, but I'm not sure why. | 09:15 |
| WebMaven | it's in the Interface, | 09:15 |
| WebMaven | I use the Interface to decalere the security | 09:15 |
| srichter | well, then it might be missing, which causes the error as well | 09:15 |
| srichter | put in a break point | 09:16 |
| WebMaven | missing how? | 09:16 |
| WebMaven | you mean from the class? | 09:16 |
| srichter | it might be non-existent | 09:16 |
| WebMaven | in the form, you mean? | 09:16 |
| srichter | security proxies will mask attribute errors | 09:16 |
| srichter | yes | 09:16 |
| WebMaven | Huh. | 09:17 |
| WebMaven | I didn't realize it had to be there if I was ignoring it. | 09:17 |
| WebMaven | OK, that explains it. Thanks. | 09:17 |
| WebMaven | no, wait, that doesn't make sense. | 09:18 |
| WebMaven | since when can't I omit a field from a form? | 09:18 |
| srichter | just put in a break point, remove the security proxy and see what the original problem is | 09:18 |
| WebMaven | form_fields = form.FormFields(IPage).omit('__parent__','page_isvalid') | 09:18 |
| srichter | you can | 09:18 |
| srichter | but you specifically assign self.context.page_isvalid there | 09:19 |
| srichter | I bet you it is not security declared | 09:19 |
| WebMaven | Maybe I'm confused. It is in the IPage schema, and I declare it like this: | 09:20 |
| WebMaven | <require | 09:20 |
| WebMaven | permission="zope.ManageContent" | 09:20 |
| WebMaven | set_schema=".interfaces.IPage" | 09:20 |
| WebMaven | /> | 09:20 |
| srichter | well, how is it declared in IPage? | 09:21 |
| WebMaven | page_isvalid = zope.schema.Bool( | 09:21 |
| WebMaven | title = _(u'Valid XML'), | 09:21 |
| WebMaven | description = _(u'The validity of the page XML'), | 09:21 |
| WebMaven | required = False, | 09:21 |
| WebMaven | readonly = True) | 09:21 |
| srichter | ok, all this is correct | 09:22 |
| srichter | you really need to debug there | 09:22 |
| WebMaven | OK. | 09:22 |
| srichter | to check out what self.context is | 09:22 |
| srichter | see what the error without the security proxy is, etc | 09:22 |
| WebMaven | This is embarrasing, but I'm still not comfortable with pdb. Do you have the patience to walk me through it? | 09:23 |

| WebMaven | srichter: ? | 09:26 |
| WebMaven | OK, I guess not. | 09:30 |
| naro | WebMaven: I can help you with pdb a bit | 09:30 |
| naro | WebMaven: before the line self.context.page_isvalid, self.context.page_error = xmlerror enter the following line: | 09:30 |
| naro | import pdb; pdb.set_trace() | 09:31 |
| WebMaven | OK, done | 09:31 |
| naro | and start zope on foreground (zopectl fg or runzope) | 09:31 |
| WebMaven | thanks, BTW | 09:31 |
| naro | np | 09:31 |
| WebMaven | OK. | 09:32 |
| WebMaven | now what? | 09:32 |
| naro | follow your browser to reach the code (Apply changes action) and look to zope console. There should be (pdb) prompt | 09:32 |
| naro | and your browser will freeze (waiting for server) | 09:32 |
| WebMaven | yes | 09:33 |
| naro | now you can try to enter "self.context" or "print self.context" to the pdb prompt. I don't know why, but sometimes is breakpoint reached inside the set_trace method, so there is no self.context. In this case enter "n" (next) command and try self.context again | 09:34 |
| naro | you can see what is in self.context variable now. got it ? | 09:34 |
| WebMaven | self.context | 09:35 |
| WebMaven | <rogue.courses.page.Page object at 0xb6a4450c> | 09:35 |
| naro | great | 09:35 |
| naro | now | 09:35 |
| naro | there are several pdb commands I'm using: n(next) command; c(continue) running of program, s(step) into function r(return) from function | 09:36 |
| naro | p - print variable | 09:36 |
| naro | read pdb documentation for full set of commands | 09:36 |
| naro | look for pdb.txt in your python library (/usr/lib/python2.4) | 09:37 |
| romanofski | moin | 09:38 |
| naro | I can't hel you to solve your zope related problem, I'm still zope3 newbie and I do not know what you are doing :) | 09:38 |
| naro | good morning | 09:38 |
| WebMaven | OK. | 09:38 |
| naro | WebMaven: so, after you find what you need, use "c" command to continue your session in browser | 09:39 |

| srichter | naro: when running tests, the breakpoint ends in the test code; then you go one stack item up (u) to get to the right context | 09:41 |
| WebMaven | naro: srichter was saying I needed to remove the security proxy... | 09:41 |
| srichter | from zope.security.proxy import removeSecurityProxy | 09:41 |
| naro | srichter: ok | 09:42 |
| srichter | removeSecurityProxy(self.context) | 09:42 |
| naro | WebMaven: btw, I'm using WingIDE for Zope2 debugging long time and together with z3wingdbg it is possible to use it with Zope3 as well. | 09:43 |
| naro | but WingIDE is not free product | 09:43 |
| WebMaven | OK, it came back at me with | 09:43 |
| WebMaven | <rogue.courses.page.Page object at 0xb6a4450c> | 09:43 |
| srichter | store that | 09:44 |
| srichter | as a variable | 09:44 |
| naro | obj = removeSecurityProxy(self.context) | 09:44 |
| srichter | and then try accessing/assigning to the attribute | 09:44 |
| WebMaven | Ah, OK. | 09:44 |
| WebMaven | obj.page_isvalid | 09:45 |
| WebMaven | False | 09:45 |
| srichter | can you assign to it? | 09:45 |
| srichter | especially the value you originally wanted? | 09:45 |
| WebMaven | yes: | 09:46 |
| WebMaven | (Pdb) obj.page_isvalid = True | 09:46 |
| WebMaven | (Pdb) obj.page_isvalid | 09:46 |
| WebMaven | True | 09:46 |
| srichter | is that the calue that the original code tried to set? | 09:46 |
| srichter | if so, then you have a security declaration problem | 09:46 |
| naro | WebMaven: print xmlerror | 09:47 |
| WebMaven | (Pdb) print xmlerror | 09:47 |
| WebMaven | (True, '') | 09:47 |
| naro | you do not need to use 'print' command, 'xmlerror' is sufficient | 09:47 |
| WebMaven | err, yes. | 09:48 |
| WebMaven | OK, but I *declared* the security... | 09:49 |
| naro | if you use (n)ext command now, you should get the ForbiddenAttribute error | 09:49 |
| WebMaven | yes | 09:49 |
| WebMaven | ForbiddenAttribute: ('page_isvalid', <rogue.c...b6a4450c>) | 09:49 |
| WebMaven | > /home/webmaven/Desktop/ZopeRogue2/lib/python/rogue/courses/browser/page.py(57)handle_edit_view_action() | 09:49 |
| WebMaven | -> self.context.page_isvalid, self.context.page_error = xmlerror | 09:49 |
| * WebMaven looks at his code again... | 09:53 | |
| WebMaven | it's declared in the interface. | 09:55 |
| WebMaven | I use the interface to declare security | 09:55 |
| *** ivan has joined #zope3-dev | 09:55 | |
| WebMaven | The class implements the interface | 09:55 |
| WebMaven | it has the matching FieldProperty | 09:55 |
| WebMaven | The form omits the field | 09:56 |
| WebMaven | The add form omits the field too. | 09:57 |
| WebMaven | Adding succeeds (and the init does the equivalent successfully) | 09:57 |
| WebMaven | Could the security proxy be pitching a fit because I'm trying to access a field that I omitted from the form? | 09:58 |
| WebMaven | no, restoring the form makes no difference. | 10:04 |
| WebMaven | I mean, restoring the field | 10:04 |
| WebMaven | srichter: where else could I be missing a security declaration? | 10:05 |
| WebMaven | Wait, could it be the readonly declaration? | 10:06 |
| WebMaven | no, removing the readonly has no effect. | 10:11 |
| *** ivan has quit IRC | 10:11 | |
| WebMaven | What security declaration am I missing? This is very vexing. | 10:12 |

| *** __gotchaway has joined #zope3-dev | 10:17 | |
| WebMaven | srichter: what else can I investigate? | 10:17 |
| WebMaven | OK, so I reversed the order of the assignments, page_error has the same problem. | 10:20 |
| *** stu1 is now known as stub | 10:25 | |
| tahara | Hi. WebMaven, you can use checker for investigation. | 10:26 |
| WebMaven | ?? | 10:26 |
| tahara | from zope.security._proxy import getChecker | 10:27 |
| WebMaven | in pdb? | 10:27 |
| tahara | yes. | 10:27 |
| tahara | checker = getChecker(self.context) | 10:27 |
| tahara | I think variable checker is CombinedChecker instance, | 10:28 |
| tahara | so you can check the permission setting by following code... | 10:28 |
| *** jfroche has joined #zope3-dev | 10:28 | |
| tahara | checker._checker2.set_permissions | 10:28 |
| tahara | and | 10:28 |
| tahara | checker._checker2.get_permissions | 10:28 |
| tahara | then you can see your object's permission information. | 10:29 |
| WebMaven | Hmm. | 10:31 |
| WebMaven | (Pdb) checker._checker2.set_permissions | 10:31 |
| WebMaven | *** AttributeError: 'zope.security.checker.Checker' object has no attribute '_checker2' | 10:31 |
| WebMaven | (Pdb) | 10:31 |
| tahara | so, checker is not a CombinedChecker. | 10:32 |
| tahara | ok, please write "checker.set_permissions". | 10:32 |
| WebMaven | by itself? | 10:33 |
| tahara | yes. | 10:33 |

| WebMaven | so, those two attributes have no declaration, just like srichter thought. | 10:34 |
| WebMaven | But why? | 10:34 |
| tahara | hmm.others are same as you wrote? | 10:35 |

| tahara | hmm, I don't like custom widget too. But I have no idea... | 11:14 |
| tahara | if you don't need to display those attributes, then you can omit them from fields. | 11:15 |

| tahara | I was misunderstanding, a readonly field is always display only in form. | 11:40 |
| *** opetznick has joined #zope3-dev | 11:41 | |
| tahara | I think readonly field is fit for your purpose. | 11:45 |
| WebMaven | tahara: yes, but that is preventing me from setting the value. | 11:49 |
| WebMaven | My code needs to set the value, not the user. | 11:50 |

| WebMaven | Ahh... | 12:08 |
| *** yvl has joined #zope3-dev | 12:09 | |
| WebMaven | OK, for those of you who have been following along, here is the answer for making a form field display only *without* making it read only: | 12:09 |
| WebMaven | form_fields = form.FormFields(IPage).omit('__parent__','page_isvalid') | 12:09 |
| WebMaven | form_fields['page_error'].for_display = True | 12:09 |
| WebMaven | Damn, that was a pain in the ass to figure out. | 12:10 |
| * baijum added this to FAQ (http://wiki.zope.org/zope3/FAQ#how-to-make-a-form-field-display-only), thanks WebMaven ! | 12:19 | |
| WebMaven | you're welcome. | 12:21 |
| *** jinty has joined #zope3-dev | 12:23 | |
| philiKON_ | WebMaven: a look at IFormFields in zope.formlib would've done the trick :) | 12:23 |
| philiKON_ | you should never have to change your schema definition just the manipulate a form | 12:23 |
| philiKON_ | and baijum, that faq entry is wrong | 12:24 |
| philiKON_ | ah, never mind | 12:24 |
| philiKON_ | sorry, misread | 12:24 |
| WebMaven | so, this *is* the correct solution? | 12:24 |
| philiKON_ | for_display is correct, yes | 12:24 |
| WebMaven | OK. | 12:26 |
| WebMaven | this was all because I need to do validation that wouldn't prevent the form from being saved. Sigh. | 12:28 |
| WebMaven | Well, it works now. | 12:29 |
| WebMaven | both storing and displaying the XML schema validation error. | 12:29 |

| *** jfroche__ has joined #zope3-dev | 13:03 | |
| baijum | philiKON_, We are using 'zope' as a pure namespace package, but persitence is not like that, and it is very convenient to use 'import persistent' then use 'persistent.dict', but, may be to reduce the overall import speed it's done like that (and not everyone uses persistent.dict) | 13:09 |
| philiKON_ | it's also standard python import rules | 13:09 |
| philiKON_ | if you want to use something you should import it explicitly | 13:09 |
| *** jfroche_ has quit IRC | 13:11 | |
| *** niemeyer has joined #zope3-dev | 13:12 | |
| baijum | philiKON_, I think the module creator can decide on that, see I can 'import os' then use 'os.path' (but it should be documented like: http://docs.python.org/lib/module-os.html see bottom) | 13:15 |
| philiKON_ | i actually dislike the fact that you can simply import os and get os.path for free | 13:15 |
| baijum | but it's very convenient | 13:17 |
| baijum | anyway, in the case of 'persistent' we need not to do like that | 13:17 |

| ivan | this is creating the subwidgets, filling with values | 16:15 |
| ivan | for i, item in enumerate(data): | 16:15 |
| ivan | widget = self._getWidget(i) | 16:15 |
| ivan | widget.setRenderedValue(item) | 16:15 |
| ivan | widgets.append(widget) | 16:15 |
| mgedmin | use a pastebot, please | 16:16 |
| mgedmin | see /topic | 16:16 |
| ivan | sorry this is the first time i'm here | 16:18 |
| ivan | what does pastebot means? | 16:18 |
| mgedmin | no problem | 16:18 |
| mgedmin | you go to http://zope3.pastey.net/ | 16:18 |
| mgedmin | paste your code into the form there | 16:18 |
| ivan | and? | 16:18 |
| mgedmin | then paste the numbered link you get here | 16:18 |
| ivan | ok | 16:18 |
| mgedmin | as a result you can show us large amounts of code without flooding the IRC channel | 16:18 |
| ivan | sure | 16:20 |
| ivan | http://zope3.pastey.net/5803 | 16:20 |
| ivan | this is my submit | 16:20 |
| ivan | the item in the highlighted row is _Proxy types | 16:21 |
| ivan | typed | 16:21 |
| ivan | therefore i see nothing in the view screen, just a big empty table | 16:21 |
| mgedmin | you may need to use zope.security.proxy.removeSecurityProxy() on it | 16:22 |
| ivan | yes, i did this and then i get the values | 16:22 |
| ivan | i used removeAllProxies() | 16:23 |
| ivan | so i have to subclass SequenceDisplayTableWidget and modify the widgets method? | 16:24 |
| mgedmin | hm | 16:25 |
| mgedmin | what sort of objects are they? | 16:25 |
| mgedmin | do you have security declarations for them? | 16:25 |

| faassen | philiKON_: hey | 16:47 |
| faassen | philiKON_: traversal question, if you have time :) | 16:48 |
| * mgedmin wants to see the question | 16:49 | |
| faassen | mgedmin: well, it's a zope 2 question as well :) | 16:49 |
| * mgedmin retracts his wish | 16:50 | |
| faassen | basically in Zope 2.10, traversal happens in one way for resources and views, and in another way for everything else. | 16:50 |
| faassen | for everything else, it uses DefaultPublishTraverse, or whatever you override that with by registering a multiadapter for IBrowserPublisher. | 16:51 |
| faassen | but for resources and views, that adapter is not in play somehow. | 16:51 |
| faassen | and instead an adapter on ITraversable (possibly a multiadapter if request is in play) is used. | 16:51 |
| faassen | I'm wondering whether it's that way in Zope 3, and whether Zope 2.10 is doing it right. | 16:52 |
| faassen | mgedmin: my general comment about Zope 3's traversal infrastructure is that I hope it can be made a lot simpler. :) | 16:52 |
| mgedmin | that would be nice | 16:53 |

| timte | It seems zope take about 9 seconds to return a 100 kb file. Isn't that a bit much? | 17:01 |
| faassen | timte: sounds much to me. you could use tramline to speed that up, if you're using apache. | 17:01 |
| faassen | http://www.infrae.com/products/tramline | 17:01 |
| timte | suppose I could | 17:02 |
| timte | right now I'm just curious why it takes so much time though | 17:02 |
| timte | can I profile zope somehow? | 17:03 |
| faassen | probably :) | 17:03 |
| mgedmin | http://mg.pov.lt/blog/profiling.html could be useful | 17:04 |
| mgedmin | find an interesting function (e.g. publish) and add @profile in front | 17:04 |
| mgedmin | after from profilehooks import profile | 17:05 |
| rocky | hmm... action handlers (in formlib) are invoked before render() right? | 17:06 |

| timte | :0(sub) takes 8 seconds, wonder what that is | 17:19 |
| mgedmin | what's the file name? | 17:19 |
| mgedmin | or just pastebot the whole thing | 17:19 |
| *** grahal_ has quit IRC | 17:20 | |

| timte | ok, I'll paste | 17:20 |
| timte | http://zope3.pastey.net/5810 | 17:21 |
| mgedmin | timte: I bet that's re.sub() | 17:23 |
| timte | yeah, could be | 17:23 |
| mgedmin | it spends 10 seconds in javascript.py compress() | 17:23 |
| mgedmin | using a regexp | 17:23 |
| mgedmin | I see 'cachingadapter.py' | 17:24 |
| mgedmin | so it should be faster the next time | 17:25 |
| mgedmin | you can say @profile(skip=1) to ignore the first request if you want to see the profile of just the second one | 17:25 |
| timte | I request only the javascript file so it's ok. | 17:26 |
| timte | at the top you can see it's only called once | 17:26 |
| mgedmin | yes, I saw that | 17:27 |
| mgedmin | I was just wondering how long the second request takes | 17:27 |
| mgedmin | given that there's some caching involved | 17:27 |
| timte | takes equally long every time | 17:28 |
| mgedmin | so the caching doesn't work | 17:28 |
| mgedmin | nice :) | 17:28 |
| mgedmin | "I have a problem: I need to compress javascript files. I know, I'll use a regexp!" | 17:28 |
| mgedmin | and now there are two problems :) | 17:29 |
