[Zope-Annce] CMF 2.1 released
The CMF developer community is hereby announcing the release of CMF version 2.1.0-alpha. What is the CMF? The Zope Content Management Framework provides a set of services and content objects useful for building highly dynamic, content-oriented portal sites. The CMF provides the foundation for popular software packages such as Plone. It is intended to be easily customizable, in terms of both the types of content used and the policies and services it provides. Where do I get it? For release files, change logs, installation instructions and more please visit http://www.zope.org/Products/CMF/CMF-2.1.0-alpha. Roadmap and release information can be found at http://www.zope.org/Products/CMF/docs/roadmap. The CMF mailing list can be reached at the [EMAIL PROTECTED] address, to sign up please visit http://mail.zope.org/mailman/listinfo/zope- cmf. Please file bug reports, feature requests or suggestions in the CMF bug collector at http://www.zope.org/Collectors/CMF . What has changed since the last release? New Features - CMFDefault utils: Added getBrowserCharset function. Returns the charset preferred by the browser. Strings encoded with this charset are decoded correctly by Five.browser.decode.processInputs. - Content: Added IFactory utilities for all content classes. They are now used by default instead of the old constructor methods. - FactoryTypeInformation: Added support for Zope3 style factories. If the 'product' property of a type info instance is empty the 'factory' property is interpreted as an IFactory name. Bug Fixes - CMFCore.ActionInformation: don't use a fixed set of properties for ActionInformation. (http://www.zope.org/Collectors/CMF/232/) - CMFCore.CatalogTool: Use current executable's proxy roles, if any, in place of user's roles when computing 'allowedRolesAndUsers' for a query. (http://www.zope.org/Collectors/CMF/380) Others - skins: Changed encoding of translated portal_status_messages. Now getBrowserCharset is used to play nice with Five forms. Customized setRedirect and getMainGlobals scripts have to be updated. - FSFile: Added registration for 'txt' extension. - Profiles: All profiles are now registered by ZCML. - ZClasses: Removed unmaintained support for ZClasses. Marked the 'initializeBases*' methods as deprecated. - Content: All content classes are now registered by ZCML. ContentInit is still used to register oldstyle constructors. - Favorite: Added 'handleFavoriteAddedEvent' subscriber. This replaces the 'manage_afterAdd' hook and some code in 'addFavorite'. - CMFCatalogAware: Added 'handleObjectEvent' subscriber. This replaces the deprecated 'manage_afterAdd', 'manage_afterClone' and 'manage_beforeDelete' hooks. - setup handlers: Removed support for CMF 1.5 CMFSetup profiles. ___ Zope-Announce maillist - Zope-Announce@zope.org http://mail.zope.org/mailman/listinfo/zope-announce Zope-Announce for Announcements only - no discussions (Related lists - Users: http://mail.zope.org/mailman/listinfo/zope Developers: http://mail.zope.org/mailman/listinfo/zope-dev )

So that might mean me. :) I would like to propose setting up some sort of 'nightly build' using the buildbot already in place. We can setup it so that you don't need to change the buildbot config to point it to another release. Then whenever a release tarball is done, we poke the buildbot and an installer will show up. If the installer breaks we get some visibility at least. I'm already running a slave for pybots which has all the needed tools in place.

I am a strong favorite of (multiple) inheritance and use it excessively. I have the feeling that it makes me very productive. There is of course no conflict between the two attitudes. It may *look* like there is, though. ;) In one case, you make loads of small objects with separate concerns, and merge them into one object by multiple-inheritance. In the other case you make loads of small objects with separate concerns and merge them via adapters. The first version is less flexible, as changing the behaviour of the resulting fat objects requires subclassing, while the other attitude can be hard to overview and grasp (and hence, I'll call it greasy. Haha.) I think one generally should, in Zope3/Five, use objects as if they always need to be adapted. That is, you get the context, and you adapt it to whatever interface you need, with IMyinterface(context). Then, of course, you may very well make your object a fat object that implement all the bloody interfaces you need, instead of having multiple sets of objects and adapters, which in most cases just make things complicated. But with this attitde, that is make fat objects, but never assume they are fat when you use them, you can with little effort make something flexible. For example: The CalZope calendar attaches all views directly to the ICalendar interface. Only ICalendar objects can have these views. A calendar object in CPS is therefore a calendar that directly implements ICalendar, and some other extended interfaces with CPS support and stuff. This seems perfectly reaonable, but it turns out Plone people don't want that. They want ordinary folder to have these views. The solution to that is to attach all the views to ICalendarViewable and in all views make self.context = ICalendar(context), and this way adapt the context. By making my fat calendar objects IcalendarViewable, I need not to change any other code in CPSSharedCalendar or CalZope. I still have the same monolithic objects, that are easy to understand and debug. But for Plone, it would with these changes be perfectly possible to make adapters from Plone folders to ICalendar, and therefore use CalZope views for folders full of plone events. So, as long as you *use* the objects as if they always need to be adapted, you can very well write the objects monolithically if that suits you. So, heres a new tagline: Use your objects as if they were greasy, and it isn't a problem if they are fat. ;-) -- Lennart Regebro, Nuxeo http://www.nuxeo.com/ CPS Content Management http://www.nuxeo.org/ ___ 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 )

Perhaps. That's to be seen. For one, the CA's registries are much less magic because look-up is always explicit (as opposed to the implicit acquisition as its widely used in Zope 2). I expect this to happen as soon as Zope3 is becoming main stream and not only used by the fittest people. This is indeed a good point. There are currently efforts to make Zope 3 easier for simpler use cases that wouldn't involve dealing with those registries, at least not directly.

I am a strong favorite of (multiple) inheritance and use it excessively. I have the feeling that it makes me very productive. That's good. Again, I think multiple inheritance is a valid tool. One reason why I would advise against using is excessively, though, is the lack of pluggability. The way Zope 2 deals with APIs, for example, makes hard to reuse and customize existing components. Sure, you CAN try to reuse stuff (and I know some of your tools, e.g. rebindFunction et.al. from ReuseUtils), but most of these revolve more around implementation details than around well-defined APIs and responsibilities. ___ 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 )

dtml-call REQUEST.set('recid', '1049298593')
dtml-in Catalog({'master_recid' : recid})
dtml-call REQUEST.set('drid', data_record_id_)
/dtml-in
drid= dtml-var drid
Incorrect (typo):
dtml-in Catalog({'master_recid' : recid})
Corrected:
dtml-in Catalog({'id' : recid})
Displays:
drid= 17223047659
All is well, so far... I now want to remove the record from the ZCatalog:
dtml-call Catalog.uncatalog_object(recid)
generates the following error in my log file:
2004-07-02T11:13:07 ERROR(200) Catalog uncatalogObject unsuccessfully
attempted to uncatalog an object with a uid of 1049298593.
and
dtml-call Catalog.uncatalog_object(drid)
generates the following error in my log file:
2004-07-02T11:21:07 ERROR(200) Catalog uncatalogObject unsuccessfully
attempted to uncatalog an object with a uid of 1722304759.
So, how do you remove a 'non-catalog aware' object from a zcatalog? (this
is
the first time I have used non-catalog aware instances, in previous
projects
I used catalog-aware objects and just deleted the object in the folder and
the object was automatically removed from the zcatalog).
I don't understand why the uid of 1049298593 works in retrieving the record
from the zcatalog, but not when used to delete the record from the
zcatalog?! (I have looked at the code in Catalog.py and nothing in the
uncatalog_object method provides any hints as to why this problem is
occuring).
Any ideas would be really appreciated!
Thanks,
Jonathan

[Zope] CMF 2.1 released
The CMF developer community is hereby announcing the release of CMF version 2.1.0-alpha. What is the CMF? The Zope Content Management Framework provides a set of services and content objects useful for building highly dynamic, content-oriented portal sites. The CMF provides the foundation for popular software packages such as Plone. It is intended to be easily customizable, in terms of both the types of content used and the policies and services it provides. Where do I get it? For release files, change logs, installation instructions and more please visit http://www.zope.org/Products/CMF/CMF-2.1.0-alpha. Roadmap and release information can be found at http://www.zope.org/Products/CMF/docs/roadmap. The CMF mailing list can be reached at the [EMAIL PROTECTED] address, to sign up please visit http://mail.zope.org/mailman/listinfo/zope- cmf. Please file bug reports, feature requests or suggestions in the CMF bug collector at http://www.zope.org/Collectors/CMF . What has changed since the last release? New Features - CMFDefault utils: Added getBrowserCharset function. Returns the charset preferred by the browser. Strings encoded with this charset are decoded correctly by Five.browser.decode.processInputs. - Content: Added IFactory utilities for all content classes. They are now used by default instead of the old constructor methods. - FactoryTypeInformation: Added support for Zope3 style factories. If the 'product' property of a type info instance is empty the 'factory' property is interpreted as an IFactory name. Bug Fixes - CMFCore.ActionInformation: don't use a fixed set of properties for ActionInformation. (http://www.zope.org/Collectors/CMF/232/) - CMFCore.CatalogTool: Use current executable's proxy roles, if any, in place of user's roles when computing 'allowedRolesAndUsers' for a query. (http://www.zope.org/Collectors/CMF/380) Others - skins: Changed encoding of translated portal_status_messages. Now getBrowserCharset is used to play nice with Five forms. Customized setRedirect and getMainGlobals scripts have to be updated. - FSFile: Added registration for 'txt' extension. - Profiles: All profiles are now registered by ZCML. - ZClasses: Removed unmaintained support for ZClasses. Marked the 'initializeBases*' methods as deprecated. - Content: All content classes are now registered by ZCML. ContentInit is still used to register oldstyle constructors. - Favorite: Added 'handleFavoriteAddedEvent' subscriber. This replaces the 'manage_afterAdd' hook and some code in 'addFavorite'. - CMFCatalogAware: Added 'handleObjectEvent' subscriber. This replaces the deprecated 'manage_afterAdd', 'manage_afterClone' and 'manage_beforeDelete' hooks. - setup handlers: Removed support for CMF 1.5 CMFSetup profiles. ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] Surprising load test results? (more results)
Hi all, I have added ab tests at the end of the page. (http://talk.lastminute.com/wiki/index.php/Loadtest) These extra results confirm everything we had found so far, except for 2.10 with use-wsgi on... We could see what others reported: in 2.10, WSGI adds a similar overhead to all type of requests (html, gif, swf, ...). So there must have been something wrong in our initial test. Again, Zope 2.8.8 remains the fastest version... Something new that we could not see in the previous test is the evolution of the results with the number of concurrent threads, as we have done the same test with 1,2,5,10,20,50 and 100 threads. Please have a look, and let me know what you think about these additional results. Thanks.

It works, but possible problem with volatile attributes persists - it is specific to Zope Database Adapters, and SQLRelay adapter uses '_v_' attributes too. Issue with 'reconnect' behaviour of SQLRelay may be that your Zope instance will appear 'hanged' when database is not running (or something like that) because Zope threads will be waiting for DB response. AFAIR there is no timeout for SQLRelay (sometimes it is good, sometimes not). Another question is what happens with transactions integrity in this situation. -- Maciej Wisniowski ___ Zope-DB mailing list Zope-DB@zope.org http://mail.zope.org/mailman/listinfo/zope-db
[Zope-DB] Zope3.3.0 - zope.rdb implementation - bug, feature or what?
Hi!
First of all sorry if it is not correct list for this question
but there is no Zope3-DB... maybe Zope3-users or
Zope3-dev?
I've just tried to use Zope3.3.0 with cx_Oracle adapter
and to check whether connection works I've used
typical for Oracle statement:
select 1 from dual
I've received error:
TypeError: __slots__ must be identifiers
The problem is (I think) with class Row or
RowClassFactory defined
in zope/rdb/__init__.py.
There is current implementation of RowClassFactory:
def RowClassFactory(columns):
Creates a Row object
klass_namespace = {}
klass_namespace['__Security_checker__'] = InstanceOnlyDescriptor(
NamesChecker(columns))
klass_namespace['__slots__'] = tuple(columns)
return type('GeneratedRowClass', (Row,), klass_namespace)
in my case:
klass_namespace is {'__slots__':('1',)}
and '1' causes error.
select 1 as abc from dual
executes correctly.
I've implemented temporary solution that simply changes
the names of numeric attributes (like '1') to prefixed ones
(like '_1') It works but I'm not sure whether it is proper
solution for something other than tests, but in general
who may use this kind of dynamically created labels for
something useful...?
Is this issue a bug or feature or something else. I'm not able to
recognise them myself (especially after submitting
request.locale issue on z3-five list :)).
I would like to know your's opinions
before submiting a bug and/or trying to create a patch.
