Speed win in Python's urllib.quote
by Tres Seaver 13 Sep '05

13 Sep '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 While profiling a page full of dynamically-generated links, I was interested to see Python's 'urllib._fast_quote' show up quite high in the total time list. After looking at it, I have found a pretty huge speed win available, posted to Python's SF tracker as bug #1285086: https://sourceforge.net/tracker/index.php?func=detail&aid=1285086&group_id=… Zope makes *heavy* use of urllib.quote (quoting each element of the path in 'absolute_url', for instance), which makes it a particularly interesting speedup for us. I'm attaching the speed test and the patch, for consideration by the Zope development community: if this is enough of a win, we might consider including a patched urllib in Zope2/Zope3 (or monkey-patching urllib.quote).

indexing multiple strings with ZCTextIndex broken in Zope 2.7.7
by Martijn Faassen 05 Sep '05

05 Sep '05

Hi there, The behavior of ZCTextIndex was intended to be able to index strings, but also lists of strings. The list of strings construction is useful in case one wants to index multiple pieces of text without generating patterns that aren't really there: ['foo bar', 'qux baz'] but we don't want 'bar qux' to be a pattern. Zope 2.7.7 appears to break this behavior due to a change in index_object in Products/ZCTextIndex/ZCTextIndex.py, and only accepts strings, not lists of strings anymore. The underlying indexing code is however capable of dealing with lists of strings. This problem has evidentially been broken and fixed on the Zope 2.8 branch, but remains on the Zope 2.7 branch. This comment is also present on Zope 2.8: Enter the document with the specified documentId in the index under the terms extracted from the indexed text attributes, each of which should yield either a string or a list of strings Are there plans for a Zope 2.7.8 that fixes this? The Zope 2.7 branch in CVS still appears to be broken. Regards, Martijn

Zope3 / ERP Project Launched
by Aurélien Calonne 31 Aug '05

31 Aug '05

Hi, On the behalf of ERP5 developer community,I am pleased to announce Zope3 / ERP Project and its new moto: "no overhead, high performance". The goal of the Z3ERP project is to leverage the Zope3 platform and build an ERP solution based on ERP5 technologies with the capability of handling more than 1,000 concurrent users or 1,000,000,000 business records and compete with the famous proprietary ERP solutions. The project has been discussed with ERP5 developers and customers in Africa, Americas, Asia and Europe for now one year. Initial high performance experimentations have been conducted with success and give us the confidence that this goal can be reached. Besides high performance, the project aims at providing full compatibility with Zope2 implementations of ERP5, developing Javascript Web user interfaces (AJAX) which increase enterprise productivity and are compatible with high latency WAN networks, creating predefined localisation guidelines and developing efficient model based configuration solutions. The project will be organised through a series of sprints and experience build-up sessions. Sprint activities are open to experienced ERP5 developers. Training sessions will be organised in parallel for experienced Zope developers who wish to gain ERP5 experience and participate in the next sprint. Project events will be published on www.z3erp.org. The first project sesssion will happen during the DZUG meeting on September 22 and 23 in Köthen/Anhalt city. Preferred licensing of project is GPL. Hosting of the project is on a dedicated Erp5.org workspace. Any contribution must be GPL compatible (ex. ZPL). Copyright is assigned to contributor on a per component level. To prevent any legal risks resulting from mergers or buyouts, all code will be formally licensed to the Foundation for a Free Information Infrastructure (FFII), a global independent software association. All project code must be archived in the FFII repository. Nexedi has already assigned 2 full-time engineers to this project.

29 Aug '05

Hi, in Zope-2.7.7-final, there are two licences for ZServer/medusa: Zope-2.7.7-final/lib/python/ZServer/medusa/docs/README.html and Zope-2.7.7-final/lib/python/ZServer/medusa/dist/license.html Can someone please remove this inconsistency? By deleting one of these of clearing the situation otherwise.

Puzzling change to guarded_getitem in Zope 2.8
by Richard Jones 27 Aug '05

27 Aug '05

I'm migrating our 2.7-developed Product to 2.8. The following change has me puzzled. In 2.7, AccessControl.ZopeGuards guarded_getitem has the following code: def guarded_getitem(object, index): [ snip handling of slices ] ... v = object[index] if Containers(type(object)) and Containers(type(v)): # Simple type. Short circuit. return v if getSecurityManager().validate(object, object, index, v): return v raise Unauthorized, 'unauthorized access to element %s' % `i` note the use of "index" in the validate call. In 2.8, this appears as: def guarded_getitem(object, index): [ snip handling of slices ] ... v = object[index] if Containers(type(object)) and Containers(type(v)): # Simple type. Short circuit. return v if getSecurityManager().validate(object, object, None, v): return v raise Unauthorized, 'unauthorized access to element %s' % `i` where "index" has become "None". This would appear to imply that we can't perform access controls on a per-item basis in sequences or mappings, unless we do so in the actual __getitem__ method, which implies there's no such thing as trusted code. We have an access policy implementation of: def _checkAccess(self, name, value): if name.startswith('CG'): return 1 if self.isValidAggregateName(name): return 1 return 0 security.setDefaultAccess(_checkAccess) which obviously doesn't work any more, since "name" is never a item name, it's always None.

Create Zope 2.9 project wiki
by Fred Drake 26 Aug '05

26 Aug '05

I've created a project wiki for Zope 2.9: http://www.zope.org/Wikis/DevSite/Projects/Zope2.9/FrontPage The wiki is pretty bare at the moment. I've started adding some notes about moving the build and packaging support to use zpkg in the Tasks page: http://www.zope.org/Wikis/DevSite/Projects/Zope2.9/Tasks Feel free to start filling in other parts of the wiki as well. -Fred -- Fred L.

Build process for Zope 2.9
by Fred Drake 26 Aug '05

26 Aug '05

Hey all, I'm working on a revised build process for Zope 2.9, based on the work that we've done for Zope 3. What this means is that we'll have a setup.py that uses the code from zpkg (http://www.zope.org/Members/fdrake/zpkgtools/) to load metadata from the various packages are part of the checkout, and use distutils to perform the build. One thing that will need to change is the makefile that gets generated by the configure script. The current makefile has an enormous number of options that don't really seem to make sense, and many targets. I'd like to remove any that aren't being actively used, but it's hard to tell which those are. Would anyone object if we switch to something a lot closer to the Zope 3 makefile? There's basically in-place builds and tests, and that's it. Everything else is handled outside the makefile. Comments or objections? -Fred -- Fred L.

3rd party product migrations
by Alan Milligan 26 Aug '05

26 Aug '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, We're now migrating our product stack to Zope2.8/Plone2.1 and have been considering how best to proceed with this. We have one overriding objective in that we're very interested in reducing the window between core releases and third party developers making new releases both now and into the future. To this end, we've set up a development channel, synonymous with Rawhide for those familiar with Redhat/Fedora release management practices. Using yum or up2date, you can access this channel at https://linux.last-bastion.net/RPC2/up2date/development to transparently upgrade to the latest core. We will be producing regular releases of things Zope and Plone into the future here. At this stage, you do need to create an account on the portal as you need to be Authenticated to download. The Zope2.8/Plone2.1 packages happily sit alongside older installations. If you're an author of anything on https://linux.last-bastion.net/RPC2/up2date/plope, we're particularly keen upon getting you involved. If you've a Plope product you'd like to get put on this channel, then please do feel free to contact us. We're hoping to grow the list of successfully migrated packages as quickly as possible. We of course realise that the Zope and Plone landscape is diverse, both in terms of finding source code, and operating system environments, but if you're even remotely interested in packaging, or have something to say, please feel free to subscribe to maintainers-subscribe(a)linux.last-bastion.net.
