Proposal: refactoring of zope.app.security
by Dan Korostelev 20 Mar '09

20 Mar '09

Hi people! One of most large packages that really wants to be refactored but still wasn't touched is zope.app.security. It has much in it and it brings many dependencies, including zope.app.form and company. And even some zope.* packages, like zope.securitypolicy still depend on it. So, let's finally refactor it :) Here's a sketch of a refactoring plan I wrote after taking a quick look at the current package: - Move IAuthentication and other interfaces into new zope.authentication package. Also move there PrincipalSource and the "checkPrincipal" utility function. Also move there the PrincipalTerms class, however that will add dependency on zope.browser (which is really really tiny, as you may know). - Move global principal registry, its IPrincipal/IGroup implementations and its directives into new zope.principalregistry package. - Move LocalPermission into new zope.localpermission package. I personally didn't ever need local permissions. - Rewrite PermissionsVocabulary and PermissionIdsVocabulary not to depend on zope.app.component and move them into zope.security. It's generally useful there and won't introduce any new dependencies. - Move zcml definition of zope.Public permission. Maybe move security declaration for the `zope.security.permission.Permission` class as well. - Leave all browser views, globalmodules.zcml, _protections.zcml, other zope.* permission definitions in zope.app.security as well as backward-compatibility imports. - Just to note: the "settings" module was recently moved to zope.securitypolicy as there's the right place for it. Not sure about: - ILoginPassword and its basic implementations. The interface should probably go into zope.authentication while implementations - into zope.publisher. It will add a dependency on zope.authentication to zope.publisher, but the zope.authentication are expected to be really tiny and already installed for most applications, so I believe that it's okay. - PrincipalLogging - the adapter from zope.security.interfaces.IPrincipal to zope.publisher.interfaces.ILoggingInfo. I'd just move it into zope.publisher, because it's already tied to zope.security. - ILogoutSupported flag interface/adapter. Looks like it's only ever used for enabling/disabling the "logout" button in the UI. I'd deprecate it and leave in zope.app.security. - _protections.py module. It defines a NoProxy checker for zope.i18nmessageid.Message and adds __name__ and __parent__ attributes to _available_by_default. This module was executed in zope.app.security.__init__ and generally does useful things for most of applications. The problem is that neither zope.i18nmessage, nor zope.location already depend on zope.security. One solution is to move the protections in that packages, placing the code into "try/except ImportError" block to avoid hard dependency. -- WBR, Dan Korostelev

ContainerOrderModifiedEvent
by Alan Runyan 19 Mar '09

19 Mar '09

It looks like zope.container.contained.notifyContainerModified is the event that is sent when *any* container modification occurs. Maybe this is too coarse grain? I would like to be able to differentiate when Ordering changes take place on a container. Are there any complaints against having ordering signal a more specific event? i.e. ContainerOrderModifiedEvent? It would inherient from ContainerModifiedEvent. specifically in: - zope.container.ordered.updateOrder - OFS.Folder.OrderSupport The problem is that it is very difficult to know if the Order has changed vs. some other container attribute has been changed. -- Alan Runyan Enfold Systems, Inc. http://www.enfoldsystems.com/ phone: +1.713.942.2377x111 fax: +1.832.201.8856

zope.password
by Roger Ineichen 19 Mar '09

19 Mar '09

Hi steering group and Dan During update z3c.authenticator and replace the password with the new zope.apssword implementation, I saw that the vocabulary "Passsword Manager Names" is not available in the zope.password package. I think the password package should also provide this vocabulary. Or at least the zope.app.authentication package should not configure that. Do you see any solution to solve that problem that not both package zope.app.authentication and z3c.authenticator configure that utility within the same name (needs the exclude directive for make that working) Regards Roger Ineichen _____________________________ END OF MESSAGE

ZPT attributes and ""
by Malthe Borch 18 Mar '09

18 Mar '09

Currently, if an attribute expression evaluates to any value that's boolean False, it's omitted (e.g. 0, "", object()). I think that's unexpected. Instead, attributes should only be omitted when the expression evaluates to ``None``. How do folks feel about changing this behavior in ``zope.pagetemplate``. \malthe

It probably could be (in fact, I prototyped it there first). However, it turns out that zope.hookable has effectively *no* clients beyond zope.component, which meant that I could lose the 'install_requires' dependency altogether by moving the pure-Python bits to zope.component.

[zope.testbrowser] r84900
by Malthe Borch 18 Mar '09

18 Mar '09

Code snippet: >>> def open(self, url, data=None): >>> """See zope.testbrowser.interfaces.IBrowser""" >>> url = str(url) This string coercion is unfortunate, because ``mechanize`` accepts a (mechanize-) request-object in place of a URL string here. Using a custom request object allows us to do such things as setting the REQUEST_TYPE header string, which is not possible throught the standard API. Changeset comment: - Remove vendor import of mechanize. - Fix bug that caused HTTP exception tracebacks to differ between version 3.4.0 and 3.4.1. - Workaround for bug in Python Cookie.SimpleCookie when handling unicode strings. - Fix bug introduced in 3.4.1 that created incompatible tracebacks in doctests. This necessitated adding a patched mechanize to the source tree; patches have been sent to the mechanize project. Not sure which of the above this coercion is trying to solve, but perhaps it could be solved in a way that didn't break the mechanize functionality. \malthe
