[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.

ZopeDebugging - "Conversing With Zope" paper and a wiki
by Ken Manheimer 31 Mar '03

31 Mar '03

I presented a paper at the PyCon python conference last week, "Conversing with Zope: Interactive Debugging Using the Python Prompt", and i've put the paper in a wiki, at: http://www.zope.org/Members/klm/ZopeDebugging The paper contains techniques, tips, and hints for interacting with Zope using the python prompt and pdb. It can be eye-opening and sometimes incredibly handy to interact with Zope that way. The wiki includes the paper, a complete recipe for setting up a ZEO-based Zope site, and also space for feedback and visitor-contributed tips - this could be a place to collect and grow zope debugging wisdom... -- Ken klm(a)zope.com

CMFPortalLayout-0.1b1 released !
by Gitte Wange 31 Mar '03

31 Mar '03

Hello, Today we released the first beta version of CMF Portal Layout. From the release announce on zope.org: "CMF Portal Layout is kind of like CMF Porlets. The idea is that you can define a portal layout by defining rows and columns and filling these up with "Layout items" (like portlets). Layout can be applied to folderish content, and defines the layout for the folder and subfolders. Layout on a folder can be overwritten and changed depending on permissions, on a subfolder. At top level, manager can "lock" certain rows or columns, or selected layout items in rows and columns. Manager also defines a "Main slot", where content is presented. Rows and colums definitions are then used to generate the ZPT templates for the site. User can change the layout of their memberfolder, by adding rows and columns to their main slot, and add or remove layout items to the existing layout, if the inherited layout items aren't locked." The product can be downloaded at http://www.zope.org/Members/gittew/CMFPortalLayout/ -- Gitte Wange Technical Manager Email: gitte(a)mmmanager.org Web: http://www.mmmanager.org Tlf: +45 36 46 20 02 It starts as a benign web server with online content management... and turns into an insidious learning curve that will destroy your every waking hour. That is, until you uncover the secret that lets you do what you wanted it to in the first place. -- somebody describing the Zope experience to Jon Udell

[Ann] HCFileStorage: History controllable FileStorage
by Dieter Maurer 30 Mar '03

30 Mar '03

ZODB's FileStorage supports interesting information about modifications of the objects it maintains. The information includes when objects were changed, how they were changed and by whom they were changed. It is possible to revert to an old state. However, FileStorage provides only limited control for the management of this historical information. Packing deletes all non-current object versions before the specified pack time and effectively eliminates historical information before the pack time. HCFileStorage provides better control in that it allows the definition of history categories. A history category has a name, consists of a set of base classes and has an associated default retension time. When an object version is about to be deleted by packing, it is checked whether the object belongs to one of the defined history categories. If it does, it is only deleted when it is older than the retension time. An object belongs to the first history category such that it is an instance of one of the categories classes. The only differences between HCFileStorage and FileStorage lie in the constructor and packing. Otherwise, HCFileStorage is identical to FileStorage.

[Ann] ZopeProfiler 0.2: what Zope uses its time for
by Dieter Maurer 30 Mar '03

30 Mar '03

I have released ZopeProfiler version 0.2. ZopeProfiler helps you to understand what Zope uses its time for. It can derive both low and high level timing statistics. More information and download: <http://www.dieter.handshake.de/pyprojects/zope> New in version 0.2: * Python 2.2.2 incompatibility fixed * real time and CPU time timer (on plattforms supporting both) * much more careful monkey patching (hopefully removing a problem with WingIDE's debugging support for Zope) Dieter
