| z3noob | hi, new five user here... got a basic interfaces question: how do i have my code ask for an implementation of an interface and not care which implementation it gets? or to put it another way - where do I put the responsibility for creating some actual instance that implements my interface? | 01:39 |
| z3noob | some kind of factory? | 01:40 |
| lifeless | getUtility is a call that can perform service location by interface | 01:40 |
| z3noob | i'll look that up | 01:40 |
| z3noob | is there a better channel for newbie stuff? or is this it? | 01:41 |
| z3noob | hmm i don't think utilities are what i want - these objects i'm working with are typically used only for one request, then thrown away | 01:47 |

| z3noob | can i register an adapter for python builtin types? e.g. given a string, adapt it to my interface | 02:05 |
| dman13 | I would think you should be able to do that | 02:11 |
| *** dman13 has quit IRC | 02:11 | |
| z3noob | hmm i would think so too, but i note he didn't say how :-\ | 02:16 |
| z3noob | i tried using <adapter for="str" but doesn't seem to work | 02:22 |
| z3noob | i guess the value of "for" must be an interface | 02:23 |
| z3noob | all the examples in docs do that, anyway | 02:24 |

| SteveA | faassen: aargh. python's optimisation of calling __len__ when doing list(foo) keeps tripping me up! | 13:51 |
| mgedmin | SteveA, what do you do? | 13:51 |
| SteveA | for example, sqlobject's ResultSet has a __len__ that makes an SQL count query | 13:52 |
| faassen | SteveA: I didn't do it! | 13:52 |
| SteveA | faassen: i know! but you're a good recipient of rants! you have a weblog! | 13:52 |
| faassen | SteveA: heh. :) | 13:52 |
| faassen | SteveA: that means I'm a good generator of rants. :) | 13:52 |
| mgedmin | while True: yield random.choice(self.rants) | 13:53 |
| SteveA | so, i want to do $work on __len__ of an object | 13:53 |
| SteveA | and the object is iterable, so it makes sense to say list(object), for example, from a tal:repeat in TALES | 13:54 |
| SteveA | but, tal:repeat will call __len__, even though it doesn't really want to | 13:54 |
| SteveA | there is no way from the object in question to tell if __len__ is a legitimate call worth expending effort on, or an optimisation from list() | 13:54 |
| SteveA | i did manage to look up to the next frame, look in its names and bytecode | 13:55 |
| SteveA | and try to infer if the global list() callable was called last | 13:55 |
| SteveA | but that's kinda flaky | 13:55 |
| SteveA | i think this is a mistake in python development. python should have used a separate slot for "optimize me for list()" | 13:55 |
| SteveA | like __listlen__ | 13:56 |

| romanofski | does something similar exist like verbose security or is there a way to track, why some permissions seems not to work? | 14:08 |
| romanofski | a ++debug++security or something would be neat | 14:08 |
| *** srichter has quit IRC | 14:09 | |
| philiKON | romanofski, yeah, the Debug skin has a view for the Unauthorized exception that tells you the permission it's lacking | 14:09 |
| philiKON | ++skin++Debug | 14:09 |
| * romanofski tries that | 14:10 | |
| romanofski | hm.. it works with the debug skin, but not with my own skin | 14:12 |
| * projekt01 there is also a debug namespace ++debug++tal or ++debug++source | 14:12 | |
| romanofski | right projekt01, but you can't debug why a user isn't allowed to access a particular page | 14:13 |
| lifeless | philiKON: ok that helps then ;) | 14:14 |
| SteveA | lifeless: i'll look into that too, of course | 14:14 |
| romanofski | something like verboseSecurity in the old zope2 days | 14:14 |
| projekt01 | romanofski, yes, that's true | 14:16 |
| romanofski | philiKON: how does the skin suppose to work, if a user is unauthorized to view an object? are there little tricks or buttons I've to press? | 14:17 |
| projekt01 | romanofski, you can click on the Error view where is reporting unauthorized errors if you enable to traceback unauthorized errors. | 14:17 |
| * romanofski looks for a big red button labeled: "press here and I do what you wan't" *G | 14:17 | |
| philiKON | romanofski, the debug skin simply has a view for the Unauthorized exception | 14:18 |
| philiKON | a special view | 14:18 |
| philiKON | that exposes security details | 14:18 |
| romanofski | okey... i try to look it up | 14:18 |
| andres | romanofski, you can make the debug skin part of your skin. | 14:18 |
| romanofski | just include it in the layers right? | 14:19 |
| lifeless | SteveA: naturally ;) | 14:19 |
| andres | romanofski, yes, i did that, and it works well. | 14:19 |
| philiKON | reminds me of writing that skins+layers = 1 proposal | 14:20 |
| romanofski | sounds like a very good idea andres - thanks :) | 14:20 |

| efge | I'm trying to get a list of subscribers for an event interface, but without "running" them. How would I go about doing that? | 16:53 |
| SteveA | you'd need to dig into the component registries | 16:54 |
| SteveA | i don't believe there is a good API for getting things by interface | 16:54 |
| J1m | Use the subscriptions method on the adapter registry. | 16:54 |
| J1m | If you get hold of the current site, it has an adapters attr which is the registry. | 16:55 |
| J1m | SteveA, for the June release, I'd like to follow up on a suggestion of yours. | 16:56 |
| J1m | I'd like to make explcit objects with methods for component lookup. | 16:56 |
| J1m | (In addition to what we have now.) | 16:56 |
| philiKON | J1m, can you elaborate on that? what are "explicit objects with methods"? | 16:57 |
| J1m | This way, an app could be a bit more explicit about how/where it looks things up. | 16:57 |
| J1m | so, now we use component package methods. | 16:57 |
| philiKON | right | 16:58 |
| J1m | These hide a policy of having thread-specific "sites", | 16:58 |
| J1m | I think it's fine to have such a default policy, but I think it would be good to have the ability to say: "use this particular component source". | 16:59 |
| J1m | In certain contexts you want to use sources other than the default. | 16:59 |
| philiKON | i guess so | 16:59 |
| SteveA | thread-specific sites? | 16:59 |
| philiKON | we already have that, no? | 16:59 |
| J1m | For example, when processing ZCML, you want to use a ZCML-provides source of components. | 17:00 |
| J1m | philiKON, we have bits of this, but it's not as well thought out as it should be. | 17:00 |
| SteveA | this would make the metazcml registry of components more explicit | 17:00 |
| J1m | SteveA, the component methods use a "site". | 17:00 |
| J1m | yes | 17:01 |
| J1m | The definition of site is pluggable. | 17:01 |
| J1m | Zope plugs in a mechanism that uses separate sites for each thread. | 17:01 |
| SteveA | as well as allow various nefarious plans i'd like to try out, like having a source of components for related to something about a particular interaction | 17:01 |
| J1m | yes | 17:01 |
| J1m | which is exactly what Zope does now. | 17:01 |
| J1m | In setting up a request, we set the thread-local site to one traversed to in the request. | 17:02 |
| J1m | At the end of the request, we set the thread-local site back to the global one. | 17:02 |
| efge | J1m: ok I found my subscribers, thanks | 17:04 |
| SteveA | but i think this "component source" would be less than the current zope3 concept of a "site" | 17:06 |
| *** stub has quit IRC | 17:12 | |
| *** J1m has quit IRC | 17:14 | |
| benji | agreed, SteveA; if not, we need a better name then "site" for them | 17:16 |
| SteveA | sites carry a lot of extra stuff now | 17:16 |
| SteveA | like, the expectation of a URL traversal to them | 17:16 |
| SteveA | zodb stuff | 17:16 |
| SteveA | the expectation of a UI | 17:16 |
| SteveA | of mutability | 17:16 |
| SteveA | of having local code | 17:16 |
| SteveA | on launchpad i've had no particular use for the zope3 "site" concept as such, but i do have uses for something that says from where i look up adapters and utilities | 17:17 |
| SteveA | maybe this is a case like with TAL/TALES vs DTML. a less powerful but clearer concept takes you farther. | 17:18 |

| zbir | I'd like to contribute another zopectl command that I have to allow for Zope2-like 'zopectl run some_script.py' to allow for easy client scripting. I've got it working here. For stuff like zopeskel binaries, is it just enough to have it and the batch file working? | 17:29 |
| zbir | J1m suggested working on his branch, since it *is* a new feature | 17:30 |
| zbir | just wanted to get some other input. | 17:30 |
| zbir | also, I'm curious why the very slight extra effort isn't made in zopectl debug to put the root container in the locals - I've got a version that does. Saves having to do 'root = debugger.root()' every. single. time. | 17:32 |

| *** sashav has quit IRC | 17:34 | |
| philiKON | J1m, btw, would you care to explain why exactly we need 'Zope' to be in the tag name? | 17:38 |
| J1m | Because of a bug/missfeature in zpkg. | 17:39 |
| J1m | It constructs the tag name by combining the collection name and the release name. | 17:39 |
| J1m | I didn't find a way to get around that and I didn't want to delay things to fix it. | 17:40 |
| philiKON | J1m, intersting, because MacYET reports that a '2.9.0b1' tag name works fine on zope 2 | 17:45 |
| philiKON | (no Zope- prefix) | 17:45 |
| J1m | weird | 17:48 |
