[Zope-dev] possible bug in zope.app.publication
I'm trying to integrate lazr.restful into a Zope3 app and I was advised to
created my own publication factory. For that I did
publisher
name=LAZRWS
factory=.root.WSFactory
methods=GET POST HEAD DELETE
mimetypes=*
priority=5
/
Priority is set to 5 as opposed to priority 10 of the standard BROWSER
declaration in zope/app/publication/configure.zcml
publisher
name=BROWSER
factory=.requestpublicationfactories.BrowserFactory
methods=GET POST HEAD
mimetypes=*
priority=10
/
But although the RequestPublicationFactory class say:
The `priority` is used to define a lookup-order when multiple factories
are registered for the same method and mime-type.
the RequestPublicationFactory.lookup does not really take that into account.
So what I did on line 104 of
zope/app/publication/requestpublicationregistry.py
from operator import itemgetter
factory_lst = sorted(factory_lst, key=itemgetter('priority'))
Now it works as expected, calling canHandle of my factory and then falling
back to .requestpublicationfactories.BrowserFactory for non WS requests.
Is this really a bug or should I be doing something different?
Thanks
Gustavo

Re: [Zope-dev] New Zope 3 name: BlueBream

So, for time being I will focus on the getting started story (which is somewhat ready) then documentation, a small website ( http://bluebream.zope.org ) and before 1.0 release, an upgradation path from Zope 3.4 KGS. I am fine with calling the project as Bream for short, however BlueBream will remain. But all the framework specific packages will remain in zope and zope.app namespaces. May be we can think about bream as a namespace in future. I remember the days when I started contributing to Zope project. Zope developers were eagerly started looking at the larger Python community with cool technologies emerging out of it like WSGI, egg, Paste and other web frameworks. As a first step for adoption, eggification of Zope 3 packages was in radar for many contributors. I am glad that I was able to accelerate the project by creating a proposal: https://mail.zope.org/pipermail/zope3-dev/2006-October/020858.html To further accelerate the eggification of zope.app packages, I implemented Jim Fulton's proposal: https://mail.zope.org/pipermail/zope3-dev/2006-December/021352.html (BTW, This is the greatest appraisal I ever received from a FOSS community) With all the contributors effort, Zope 3 packages became more reusable by other projects. But the Zope 3 users were at a loss, they lost their main development discussion platform itself (zope3-dev list) and there was no releases. Then Stephan Richter created Zope 3.4 KGS, that was a good move which helped the existense. For a sucessfull web framework, few packages maintained by people with different interest in not sufficient. With BlueBream/Bream, I hope we will be able to bring together the framework developer community again. I appreciate all your support for this project. Regards, Baiju M As a new comer in zope community (a few months), I appreciate this move as well. The new name can also be seen as a excuse for a stronger and more meaningful statement: There is value in zope3 web app part and we want to continue it's development regardless of the other projects. Having read and recommended to many people philiKON zope3 book I felt all the work put into building a coherent and stable web framework was going away. Philipp, please consider a Web component Development with Bluebream in the future :) P.S - As a ibm employee, there is already too much blue going on in my day to day work :) I would vote for Bream only.

[Zope-dev] z3c.jsonrpc and zope3.4 egg versions
Hello I'm trying to use z3c.jsonrpc with Zope3.4 but I'm encountering problems with imports that z3c.jsonrpc does from zope.publisher. From http://download.zope.org/zope3.4/3.4.0/versions.cfg I see that zope.publisher for zope3.4 is 3.4.6 but the latest version of zope.publisher from svn is 3.8.0. From reading the Changes section of http://pypi.python.org/pypi/z3c.jsonrpc it seems like version 0.5.3 did changes to cope with changes of zope.publisher newer versions (newer then what comes with zope3.4). I haven't tried but I imagine that if I downgrade z3c.jsonrpc to version 0.5.2 things might work but then some questions came into my mind as i'm new to zope3 and buildout/eggs world. 1. Am I looking things in the wrong way or zope 3 components don't necessary follow the stable release of zope3 but rather a zope component version (in this case z3c.jsonrpc is following zope.publisher not zope3.4) 2. If 1 is true, I imagine that whenever I try a zope3 component It's a trial and error adventure and it's not guaranteed that developer is following zope3 versions. 3. If 2 is true, isn't there a better way to do things? :) Appreciate some help Thanks -- Gustavo Matheus Rahal IBM Linux Technology Center ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] Schema to JSON
Em Seg, 2009-06-29 às 11:18 +0100, Paul Wilson escreveu: 2009/6/29 Martijn Faassen faas...@startifact.com Hi there, Paul Wilson wrote: I'm about to embark on a module to serialize Zope schemas into the JSON format for my application, taking inspiration from z3c.schema2xml. I've had a look around SVN to see if this functionality has already been implemented but can't find anything - does anybody know whether this has already been done somewhere? I imagine lazr.restful hides functionality for this somewhere in its codebase. Perhaps one way forward would be to extract it? Maybe not, but it bears some investigation. Thanks for the hint. I'll take a look. Also, it makes sense in my mind for a schema2xml and schema2json to implement the same interface. How does Zope handle this case? With a format agnostic interface module or something? I am not sure I understand the proposal. Which interface would be the same and why would that be useful? I don't want my application to have knowledge of the format that the object tree will be serialized into - I want that to be a configuration detail. So, a simple format independent interface (with serialize and deserialize) would hide this. I was considering implementing some of the TODOs in the schema2xml package for my json version, but this would diverge their behaviour enough to spoil my hopes of switching freely between the two formats. Perhaps I'm looking at this the wrong way? I think you should just think in terms of what the API should be like before you worry about interfaces. (though interfaces are also used to look up adapters here). I've structured it internally in a very similar way to your schema2xml package, and shamelessly copied your test cases! :-) Sounds like a useful project! It's in my sandbox at the moment - all tests pass as it stands but it needs more attention I think. Regards, Paul Nice, I would be interested in helping as well. Perhaps you could open a launchpad project or something? We are planning a new web app using GWT (Google Web Toolkit) as frontend. We already have an application written in Django that spits json to a GWT interface and we are planning a new app based on zope3 (yeah, I did not like django that much, perhaps I should write about this when I get to know zope3 more...) -- Gustavo Matheus Rahal IBM Linux Technology Center ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
Re: Fwd: [Zope-dev] Options replacing DateTime with datetime!?
Hey again Lennart,
OK, I'm just going after my old notes here, and they could be wrong.
It could be that these types of timezones doesn't work in a datetime string?
Maybe. If there's a problem with parsing, I'll be happy to fix that.
The important part is that there is some sort of way to tell the
module what the local timezone is, so that you can test conversions.
Just use the POSIX-defined TZ variable, and the gettz() method
to retrieve the timezone.
from dateutil.tz import gettz
os.environ[TZ] = Brazil/East
gettz()
tzfile('/usr/share/zoneinfo/Brazil/East')
os.environ[TZ] = US/Eastern
gettz()
tzfile('/usr/share/zoneinfo/US/Eastern')
(...)
But it makes it impossible without actually modifying the modules code
somehow, and in my book, it is reasonable to call that impossible.
Just use gettz(), as explained above. You'll get a richer source
of information for free.
Of course nothing is impossible in computing.
(...)
If I monkey-patch the module for testing, then am I really testing
what goes on in production?
These are interesting statements. I won't move into discussing them
because it won't benefit the main point. If you'd enjoy some general
conceptual discussion we can do so privately.

Re: [Zope-dev] getting a dtmlfile from ZODB instead of the file system.
The problem i have is that the forms for management are always created on
the file system, like this:
index_html = DTMLFile('www/index_html', globals())
I'm sure you have your reasons. But this don't seem to hurt many people,
basically because it's not usual to change management forms without
changing the code handling it.
Best regards!
