[Ann] ZopeProfiler: high and low level timing statistics
by Dieter Maurer 02 Apr '03

02 Apr '03

ZopeProfiler provides profiling support for the development of Zope applications. It can derive both high and low level timing statistics (Zope object call and Python function call level, respectively). Unlike with the standard Zope profiling support, Zope runs normally in multi-threaded mode. Statistics gathering can be enabled/disabled dynamically via the ZopeProfiler object in the Control_Panel. This objects supports most features of Python's pstats.Stats timing analysis class and is much smarter than the standard Zope profiler. Should the features be insufficient, then statistics data can be saved to files and later analysed with Python's Stats class.

ZOPE NEWS January 27, 2002 1. DECISION TIME ON NEW ZOPE.ORG NZO is moving along thanks to the efforts of Guido, Sidnei, Jeff and others but the Zope Community has an important role to play. Should Plone be used? or the CMF? What content should be carried over to NZO and who's going to help out with this? Guido van Rossum's Latest Update on NZO http://lists.zope.org/pipermail/zope-web/2003-January/002310.html An Open Letter Advocating the use of Plone for NZO http://plone.org/Members/zwark/plone-nzo An open discussion on how to organize a community voting process for the NZO decision http://plone.org/Members/slinkp/CMF_Wiki.2003-01-25.3013/CommunityDecisionPr ocess 2. CMF 1.4: HELP WANTED Andy McKay is looking for help with the CMF 1.4 release. http://cmf.zope.org/projmgmt/project_schedule/roadmap_1_4 The relevent discussions on the CMF list: http://lists.zope.org/pipermail/zope-cmf/2003-January/thread.html#16893 3. ZOPE 3 SPRINTS December saw two Zope 3 sprints in Europe. The first, organized by Kit Blake at Infrae, brought together a large group of sprinters for a wonderful week-long session. Much was accomplished, not just in committed code, but in brainstorming and knowledge sharing. Rotterdam was a blast and Kit really did an exceptional job at running the circus. http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/InfraeSprin tathon http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/Alpha1Sprin t 4. ZOPE RELEASES In the last newsletter we discussed Jim's promise to get a Zope 3 alpha1 release out in 2002. Well, in most timezones, Jim met his promise! On Dec 31, Zope 3 officially saw its first light of day. The release had its intended impact: focus was brought to the project and the schedule. Quietly another release began to make its way out. Zope 2.6.1 beta1 was released, with fixes for some problems in 2.6.0. Another beta was scheduled for December, but that slipped. The second beta is planned for January, though no announcement has been made. 5. PLONE 1.0 RC2, FINAL IN SIGHT A second release candidate for Plone was released Jan 22. The number of translations is now up to 24! Also, if you want Plone to look different than the Norwegian Blue layout, RC2 has 8 new skins. http://plone.org/Members/runyaga/news/RC2_released 6. UPCOMING EVENTS SolutionLinux 2003 The Zope Europe Association has organized a pavilion of Zope companies and organizations for SolutionsLinux 2003, Paris, Feb 4-6. Participants include Ingeniweb, PilotSystems, Logilab, Cocof, Zope and Python Job Mart, University of Savoie, and Zopera. In conjunction with the pavilion, there is a second Zope 3 UI Sprint in Paris during the same week. http://www.zope-europe.org/sl2003/ Berne Plone Sprint The week after the Zope pavilion, there is a Plone sprint in Berne, Switzerland (Feb 10-12). Bernhard Bühlmann is organizing it, and he has an impressive list of attendees. And yes, Berne is gorgeous. http://plone.org/Members/buehlmann/PloneSprintBerne/News_Item.2002-12-06.054 9 DZUG meeting and sprint Christian Theune, Maik Jablonski, and the other DZUG'ers are planning a DZUG meeting Mar 24-27. Along with the meeting, a sprint is planned. Looks like Tres Seaver from ZC will be there as well. http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/DZUGSprint 7. ZOPE 3 NEWSLETTER NO. 6 http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/Zope3Newsl etter6 8. DISCUSSION ON IMPROVEMENTS TO ZPT If you've used Page Templates and the associated TAL functions, you've probably enjoyed the enhanced usefulness and flexibility they offer. Nevertheless, there is always room for improvement. Order of TAL operations(1) has been the topic du jour on the ZPT mailing list(2). Shane Hathaway introduced his "Mini proposal"(3) to improve TAL by adding two new attributes: tal:repeat-define and tal:repeat-condition. At issue is the fact that due to the order of operations, a tal:define or tal:condition will only be executed once when on the same element as a tal:repeat. Shane's proposal adds two attributes that would be evaluated for each repetition. Well, what looked like a fairly straight-forward request generated a storm of comments. The reactions ranged from moderate approval (4) (5) to proposals to change the order of operations and not add tags (6) to proposals of a user-defined order (7). With all the talk of changing things, the "leave well enough alone" crowd came out to play (8). At our deadline, the discussion looks to have stalled with no resolution. 1) http://www.zope.org/Documentation/Books/ZopeBook/current/AppendixC.stx#3-16 2) http://lists.zope.org/mailman/listinfo/zpt 3) http://lists.zope.org/pipermail/zpt/2003-January/004210.html 4) http://lists.zope.org/pipermail/zpt/2003-January/004248.html 5) http://lists.zope.org/pipermail/zpt/2003-January/004249.html 6) http://lists.zope.org/pipermail/zpt/2003-January/004241.html 7) http://lists.zope.org/pipermail/zpt/2003-January/004226.html 8) http://lists.zope.org/pipermail/zpt/2003-January/004244.html 9. ZOPE SOLUTIONS PROVIDERS LIST REACHES 100 As of this weekend, with the addition of TEKK <http://tekk.dk/> from Copenhagen Denmark and Uptime Systemlösungen GmbH <http://www.uptime.at/> from Vienna Austria, the Zope Solution Providers list now has 100 members. 10. CMF Portlets Reaches 0.5.1 I'm working on the next release of CMFPortlets, v 0.5.1, and the major new feature will be the interactive layout, thanks to OptionChooser 1.0, a DHTML layers switcher and chooser based on the Dynapi library, which I got to know by means of Tim Lynch, member of our community. OptionChooser is written by Dan George. CMFPortlets 0.5.1 will be released during the next week. An installer for Plone will be delayed until the release of its 1.0 version, due to remaining issues related to the behaviour of SkinnedFolders, which are the primitives for portlets. ZN: Ausum, can you give a sketch of what CMFPortlets does and what some possible, easy-to-grok applications could be? AS: Hi George, what a nice opportunity to write stuff. CMFPortlets was born from the need to offer personalized content to members, in the same way as many "my.something.com" portals, without paying the price of getting through any other processor in the middle. (No XML is needed here.) The key idea behind was to pack content into renderable container objects -the portlets, which rely on SkinnedFolders- so that they could use Zope's security and cataloguing machinery, while been able to be easily arranged in a presentation page. So, although portlets are indeed objects with a view method, we don't want nor need to watch them individually, but through a single global method, 'page_view', wich is callable from everywhere (from the root, by default). A portlet needs to be fully renderable before it gets its way to the presentation page, (aka 'workspace'). If the portlet uses CSS, it needs to contain its own styles, so that they don't disturb another portlet's look in the same workspace. (I'm working on a 'plugable' stylesheet concept so that the designer can define a general stylesheet for the site, and still allow portlets to look the way their authors wanted.). As portlets are containers, they can store anything from other portal types to just code, so that, if we store several documents, we'll see them rendered one below another; and if we store one or more methods calling things from different places, we'll see what those methods retrieve, one thing below the previous. A portlet's default view does render and show all what's inside it, but as it needs to provide itslef a graphical container to show off at the workspace, you can apply to it a "portlet_skin". (Typically boxes with a title.) Adding, renaming, deleting and setting the size properties of workspaces. Workspaces (or pages) aren't objects by themselves. Instead, 'page_view' is aimed to give you that impression, by rendering the portlets you have selected (which in their turn are a search to the catalog) in the place in page you've also selected, according to a variable living in portal_memberdata. Every time you add, delete, or rename a workspace, or change its size properties or add/delete a portlet, you retrieve and modify that variable, just that. The methods for the task live in 'portlets_garage'. Applications for portlets In its origin, portlets were meant just to provide content personalization for large B2C portals. I use it in combination with RDFSummary to display feeds in my local computer (which I used as demo for a few weeks), but in the corporate and intranet market, they can be used to allow an employee to have its own workspaces according to his role within the company. This same level of content discrimination on a personal basis is a must in large institutions like universities and even the government. There might be cases when the portlets selection is up to the end user, and there might be others where a person with the right role creates the workspaces and assigns them to the users. But the most important, from my perspective, is that it can be hooked to a personalization tool ('portal_personalization' maybe) that tracks a user's session and, based on a computer generated profile and his own needs, offers him a unique visit experience, all on the fly. I'm sorry I can't tell more within the context of this "impromptu". I hope I have covered at least some of your questions. I'll write a detailed how-to that you could quote for the next-to-tomorrow's release of Zope news. :) 11.

First public release of RevisionManager (1.0rc2)
by Philipp von Weitershausen 26 Jan '03

26 Jan '03

Hello everybody, I am proud to publicy release RevisionManager. RevisionManager is a CVS frontend product for Zope. It brings the power of revision controlling to the ZODB. I know, the idea is not new. To my knowledge, RevisionManager has two competitors: * The first one is Steve Spicklemire's ZCVSFolder product on which development seems to have stopped. Its disadvantage is that it is complicated to use and stores data as pickles. * The other one is CVSFile by Ariel Partners LLC. Here, the object you wish to revision control IS a CVSFile. Although it can behave like a PageTemplate or DTMLMethod, you cannot revision control real PageTemplates with it. If you already have a site with a large amount of PageTemplates, you will have to replace them with CVSFiles. Here is how RevisionManager does it and the advantages: * There is one instance per site, like with ZCVSFolder. That also means central settings and a central, tabular view of all managed files and their current status in CVS. * You define your settings, commit changes, update objects and view logs comfortably through the ZMI. No command line is involved. * You may revision control all objects that support FTP up and download (i.e. most standard Zope content objects). * Editors may checkout the site to their file system and use their favourite editor and standard file system tools. * It is great for keeping two Zope sites in sync and document changes on the way. RevisionManager has only been tested on Linux, but it should run on all Unices. There is no support for Windows and I don't think there ever will be. Please try it out, test it and tell me how you found it. You may download it at: http://www.zope.org/Members/philikon/RevisionManager Cheers, Phil

TriZPUG January Meeting: Current - Exploring a real world program
by Tom Bryan 25 Jan '03

25 Jan '03

The Triangle Zope/Python User Group (TriZPUG) will hold its third meeting this Wednesday, January 29, at 6:30 p.m. in Raleigh, NC. We will be meeting in the DELTA conference room(s) at Venture III, who has kindly permitted us to use their meeting room, on NCSU's Centennial Campus. Directions to Venture III are below. Hunter Matthews will be giving a talk about one of his projects: Current. Hope to see you there! Title: Current - Exploring a real world program =============================================== Current is a open-source reverse engineered up2date server (for Red Hat linux systems). It is implemented entirely in python, and uses several different kinds of technology. Data storage, network service, logging/debugging, cryptography, security and future growth are all areas covered in most programming books, but rarely do they give you an idea of what real users in real situations will hand you. This talk will attempt to do that. Directions to the TriZPUG Meeting: ============================ Note that we will be meeting in a different location from our previous meetings. If you need directions to NCSU's Centennial Campus, try the following link http://centennial.ncsu.edu/howtogethere/htgh.htm If you need directions to the Venture III building, follow this link http://lts.ncsu.edu/about/venture3.html, but skip step #3 since the meeting is after hours.

From: O'Reilly Conferences [mailto:oraconf@ora-info.ora.com] Sent: Thursday, January 23, 2003 3:56 PM Subject: oscon 2003 call for participation 2003 O'Reilly Open Source Convention Call For Participation Embracing and Extending Proprietary Software http://conferences.oreilly.com/oscon/ O'Reilly & Associates invites programmers, developers, strategists, and technical staff to submit proposals to lead tutorial and conference sessions at the 2003 Open Source Software Convention, slated for July 7-11 in Portland, OR. Proposals are due February 15, 2003. For more information please visit our OSCON website http://conferences.oreilly.com/oscon/ The theme this year is "Embracing and Extending Proprietary Software." Few companies use only one vendor's software on desktops, back office, and servers. Variety in operating systems and applications is becoming the norm, for sound financial and technical reasons. With variety comes the need for open unencumbered standards for data exchange and service interoperability. You can address the theme from any angle you like--for example, you might talk about migrating away from commercial software such as Microsoft Windows, or instead place your emphasis on coexistence.
