Zope source code version control
by Kenneth Y.K. YOUNG 10 Jan '00

10 Jan '00

Zope already supports undo via its ODB, but is it possible to do automatic versioning like CVS? That would mean no matter if I update a page (1) via Cold Fusion and then FTP up to Zope (2) via the Zope web interface I can get consistent versioning of my documents. Although I thought of somehow using CVS, it wouldn't handle both (1) and (2). If anyone can point out what's needed to make that work, I will seriously _try to_ write patches, though I don't know how difficult that would be. Is it of interest to ye developers out there?

O need a central object to manage the scheduling of the different Event objects, so on Product initialisation, ZScheduler creates a ZScheduler object in the Zope root. Even better, it adds this object to the protected objects list, so a user cannot delete it. I do provide a way of removing it when you remove the Product though, and plan to document the procedure thoroughly, if I ever get to get to work on it again. -- Martijn Pieters, Software Engineer | Digital Creations http://www.digicool.com | Creators of Zope http://www.zope.org | mailto:mj@digicool.com ICQ: 4532236 | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 -------------------------------------------

Product Guidelines skeleton
by Martijn Faassen 10 Jan '00

10 Jan '00

Hi there, As promised, I've created a skeleton document that will hopefully one day be filled with guidelines for product writers. The document should contain what a product should behave like, conform to, look like, and so on. Right now it's a virtually empty skeleton, but take a look and feel free to discuss it on the list (preferably zope-dev instead of zdp; this is more than just a documentation issue; we're in fact _creating_ the guidelines as we go, which seems to be something more for zope-dev). If you want to take a look at it, it's here: http://www.zope.org/Members/faassen/product_guidelines This is the structured text source in case you feel the writing bug: http://www.zope.org/Members/faassen/product_guidelines_stx Please reply to the zope-dev list if you have some product guideline issues that I've missed there, or have any other kind of comment. Regards, Martijn

memory error on BSDi [Q]
by Bruno Mattarollo 10 Jan '00

10 Jan '00

Hello... I had the following traceback on a Zope-2.0.1 that we are using on a BSDi with a virtual kernel. I had problems compiling it but finally it did... It has been running with lots of problems since then and now I have seen this traceback ... chicos: {6} % Unhandled exception in thread: Traceback (innermost last): File "/usr/home/chicos/usr/local/ZopeChicosNet/ZServer/PubCore/ZServerPublisher.py", line 95, in __init__ response=response) File "/usr/home/chicos/usr/local/ZopeChicosNet/lib/python/ZPublisher/Publish.py", line 224, in publish_module response.exception() File "/usr/home/chicos/usr/local/ZopeChicosNet/lib/python/ZPublisher/HTTPResponse.py", line 630, in exception elif lower(strip(b))[:6]=='<html>' or lower(strip(b))[:14]=='<!doctype html': MemoryError Does anyone knows when a MemoryError raise appears? Is it hardware error? If so, I will send this to our hosting rep. TIA /B Bruno Mattarollo <brunomadv(a)ciudad.com.ar>

mod_pcgi2 version 0.3.0.
by Oleg Broytmann 10 Jan '00

10 Jan '00

Hi! http://www.zope.org/Members/phd/mod_pcgi2 Implemented new command PCGI_SetEnv to set environment variable specific to this location. I use this to pass SiteRootPATH env var to SiteAccess object. This completes virtual hosting support. I converted my sites to use the module instead of RewriteRule and Zope.cgi: http://sun.med.ru/pcgi/ http://sun.med.ru/pcgi/Random http://sun.med.ru/~zphd/ - this served by root folder "phd02"; SiteAccess is used for virtual hosting. I found and traced minor problem in the using of buffer "t". I fixed the problem by extending it 1 char more - made it 11 chars instead of 10 (HDRLEN) - and zero-fill it before using. I found yet another problem and will fix it in 0.4.0. It seems I copied too much from Andrew's mod_pcgi :) I need to change pcgiStartProc back to double-fork. With current code, Apache remembers PID of started process and kills it on stop or restart.

Notes on a Zope IDE
by Eron Lloyd 10 Jan '00

10 Jan '00

Greetings all; I'm a (fairly) new Zope developer, and I've been following the discussion of the ZIDE lately. A few months ago I scoured the mail-list archive and put together some notes pertaining to this effort. They can be read at my section on zope.org, at www.zope.org/Members/Earthtone/ZGUI I'm a long-time Homesite user, and see the potential for Zope's future with the integration of nice editing/management tool. Particularily, I'd like to see a nice editor with good DTML/Python support, that can access Zope through WebDAV or XML-RPC. I've lately been looking at wxPython and Java for this. Soon I might begin a prototype, and try to solicit support from the community to aide in it's development. Any ideas on this would be appreciated. I'm working on a fairly complex Zope based project, and having a good IDE would help development/maintenance enormously. Thanks in advance, Eron Lloyd

Hmm, I think the "file location" mechanism for ExternalMethods was changed recently to allow product developers to put external methods in an 'Extensions' subdirectory under their product (this was always supposed to work, according to the docs, but didn't; now, it does). Could we use the same logic for imports, such that typing 'FooProduct.demo.zexp' would check an 'import' directory under 'FooProduct'? -- ========================================================= Tres Seaver tseaver(a)palladion.com 713-523-6582 Palladion Software http://www.palladion.com

Re: [Zope-dev] Zope/CORBA integration proposal
by Josh Zeidner 09 Jan '00

09 Jan '00

Tres, A Zope/CORBA bridge would be extremely useful... In my view Zope has its major utility as a small-scale dynamic content server. A CORBA bridge would allow Zope to integrate with : 1) Server side and Client side Java, the largest growth area in the server-side dev market. 2) High-End distributed systems( mainly in the financial industry ).

Zope/CORBA integration proposal

Spurred by the recent questions about CORBA integration, I have revisited my notes on integrating Zope with external CORBA servers, and put a version up for your review and comments: http://www.zope.org/Members/tseaver/CosNaming/Requirements/index_html Let me know what you think! Tres.

searching/viewing Zope source?
by Jon Udell 09 Jan '00

09 Jan '00

On the "eat your own dogfood" principle, I decided today that since -- let's face it -- the Zope Python, DTML, and C source files *are* the definitive documentation -- I ought to index them, and why not with ZCatalog? First, I imported /zope/lib/python into Zope. Which took longer than I expected, mainly because although I remembered having used fsimport.py in Zope 1.x, I could not find it in 2.x, nor in any searchable Zope place I could think of (zope.org, egroups.com, altavista, deja.com, etc.). Fortunately, I found a backup of Zope 1 that had fsimport.py, so I set it up as an external method, made a Zopedir called src, and ran this: http://host/src/fsimport?fsdir=/usr/zope2/lib/python Cool. Now the source tree is in Zope. I added a ZCatalog to the src folder, and told it to add everything. I'd have liked to have added just *.py, *.dtml, and *.c, but none of the strings I could think of typing into the with ids: containing: expr: boxes of the "Find Items to ZCatalog" seemed to find anything. I'm guessing that regexps can be used here somewhere, but none of the usual suspects (zope.org, egroups.com, altavista, deja.com, etc.) yielded any clues. (This, of course, is *why* I was trying to index the source in the first place!) Whatever, I just took the whole lot, 800 and some files. Then tried searching, and realized -- oops, no text index, only a meta_data index. After searching the usual suspects again (zope.org, egroups.....) I came up with the idea of indexing the 'data' attribute of the File objects. But no joy. It's looking like either: a) wrap those files, in some way, so that they have a catalog-able attribute (which I guess means changing fsimport.py?) or b) use a conventional search engine I guess b) sounds easier :-) The reason for all this is that I've begun, finally, to be productive in Zope. I would like to be much more productive. I think one thing that would help me would be something like Mozilla's searchable, cross-referenced source viewer: <http://lxr.mozilla.org/seamonkey/> I wonder if there's a tool like this that groks Python syntax rather than C? -- Jon Udell | <http://udell.roninhouse.com/> | 603-355-8980
