Zope: http://www.zope.org/ does object caching and object deactivation. Zope was the combination of Bobo, Principia (our old commercial product), and our relational database intergration software. The Zope object database is perfectly usable outside of the rest of Zope. Good luck! --Paul

Using Zope to generate static HTML on a Mac

Actually, this would be a fantastic tool for me as well. Which brings up another question: Anyone succeed in getting Zope running on the Macintosh?

BoboPOS: Large Dictionary questions
by Brian Kelley 19 Feb '99

19 Feb '99

Hello all. Due to a recent post on comp.lang.python "Large Dictionaries" I have been looking at BoboPOS as a potential solution. I have been trying to muck through the available documentation to arrive at some simple, minimal-code versions of basic tasks (sort of a mini-howto for large Dictionaries). Basic Task #1 Store/Retrieve simple picklable objects from BoboPOS import PickleDictionary from BoboPOS import Persistence pd = PickleDictionary("/tmp/pickle_dict") # begin a transaction get_transaction().begin() pd[1] = "This is a test for entry 1" pd[2] = "This is a test for entry 2" # commit the changes to the database get_transaction().commit() del pd # did this work? pd = PickleDictionary("pickle_dict") print pd[1] print pd[2] del pd The above code works well (it, perhaps, is not minimal). The problem I am having is that the above implementation will not cache. Suppose the transaction is in a loop: for i in range(10000): pd[i] = "Entry for key int(%i)"%i The memory used by this implementation is the same as the size of the "pickle_dict" file. I have looked through the source code and noticed that what I might actually want to use is a Transactional Pickle Dictionary which apparently does call the internal jar.cache.minimize() . Alghough the cache.minimize is only called during the abort() function which confuses me. The question is: How do I make large pickle dictionaries cache? Of course, this particular thread might be well used in a how-to. If such a beast already exists, please point me in the right direction. In any case, the results of this query will probably be posted to comp.lang.python as a service to the community and to promote Zope. Thanks. -- Brian Kelley w 505 995-8188 Bioreason, Inc f 505 995-8186 309 Johnson Av Santa Fe, NM 87501 kelley(a)bioreason.com

I can't get the egroup search to work from the zope.org site. When I go directly to egroups, I can't find the zope list. Something appears to be wrong. John

Netscape Web Server Plugins
by solberg＠platinum.com 19 Feb '99

19 Feb '99

Does anyone know where I can find the Netscape Web Server Plugins that are mentioned in the Webserver doc file? In Webserver it says " Like Apache, Netscape does not pass HTTP Authorization information to CGI scripts. We have a plugin at our website that addresses this. http://www.digicool.com ". I haven't been able to find any plugins at either digicool.com or at zope.org. TIA, John M. Solberg PLATINUM technology, inc.

DTML Q
by Clint Shelby McCulloch 19 Feb '99

19 Feb '99

Hmmmm. I've been trying to persuade DTML to do something like below. The context is a document which can post to itself and fill out any form defaults to appropriately.  <select NAME="selectSkill">  <OPTION VALUE=""   selected  >   </SELECT><BR>  skills_to_enter is a document property consisting of the tokens 1-10. Skills is a tiny table with a list of skill_id's and skills. The DTML above does not properly set the REQUEST.form key to a dynamic value. Is there a better to do this sort of thing? CSM

Guestbook Product

Has anyone else noticed that the GuestBook Product no longer works in 1.10? Is it just me or what? I get a traceback of Traceback (innermost last): File "/usr/local/Zope-1.10.0pr1-src/lib/python/OFS/Application.py", line 393, in import_products product=__import__(pname, global_dict, global_dict, silly) File "/usr/local/Zope-1.10.0pr1-src/lib/python/Products/GuestBook/__init__.py", line 7, in ? import GuestBook File "/usr/local/Zope-1.10.0pr1-src/lib/python/Products/GuestBook/GuestBook.py", line 7, in ? from OFS.Document import DocumentHandler, Document ImportError: cannot import name DocumentHandler Any Ideas?

I tried it, but I got empty documents (Netscape says something like 'document contains no data'). The same module runs wit ZopeHTTPServer, I only use the ZPublisher from Zope.

RE: [Zope] Var includes
by Shaw, Howard 19 Feb '99

19 Feb '99

The challenge is that I have to do this using a string returned from an SQL query. This string must specify a multi-part reference: that is, a directory, and a file... Now, I can work around this by making it more structured; that is, the includes can only be in directory X. But I would really like to be able to put 'uid/studinfo' in the SQL and use that... Do I have to write an External Function to split the directory and perform the equivalent of nested 's to include this? I had hoped for a simple DTML based solution. > ---------- > From: Pavlos Christoforou[SMTP:pavlos@gaaros.msrc.sunysb.edu] > Sent: Friday, February 19, 1999 9:37 AM > To: Shaw, Howard > Cc: 'Zope(a)zope.org' > Subject: Re: [Zope] Var includes > > On Fri, 19 Feb 1999, Shaw, Howard wrote: > > > Using 'var' to include acquired documents is easy.

Tis true. On the other hand, only developers can use CF Studio, unless you plan to plop down several thousand dollars, ship it to you customers, and then train them on it. Put another way: what if someone outside the company wanted to change a ColdFusion page? What would be their IDE? > But there's no reason you couldn't also use CF Studio to > develop Zope/DTML > pages.

We have spent a lot of time over the last month thinking about an IDE. The direction that we are going is: o choose an IDE strategy that reinforces Open Source, rather than attempt to annoint a proprietary tool like CF Studio o base the IDE strategy on advanced standards (HTML4, CSS2, DOM, XML, RDF, and WebDAV) It appears that I'll have more to say on this in about a month. Other efforts, such as integrating PythonWorks from Pythonware, are feasible as well. > Typing angle brackets and obscure HTML tags into your browser > is a fun way > to astound and impress your non-HTML-literate friends, but I > wouldn't have > wanted to make a Georgetown/CASS questionnaire system that way.

If someone has Linux on their desktop, how do they manage CF sites? Let me ask a question that tries to quantify the situation. IMO, the current Zope IDE is pretty unproductive. On a scale of 1 to 100, its *productivity* level is about a 5 compared to NetObjects Fusion, Dreamweaver, etc. On other factors it shines -- it is based on standards, is completely portable, source code is available, is mind-numbingly easy to modify the IDE, etc. Just for argument, let's say that CF Studio is a 90. If we came out with an improved IDE that retained the factors listed above that CF Studio fails at, what number would it need to move up to for you to give an unqualified "Yes!" ?? > So if we want to use Zope for real-world tasks, one important > need in the > near term is to find a better way to do actual web page/HTML If *we* is your shop, how about...XEmacs? Using ZServer to publish your object system by HTTP, you can be *significantly* more productive: o fantastic editor that now runs deliciously on Windows o bulk copy from/to the local machine o all the ediff capabilities you could dream up o html-mode, etc. o using W3 in XEmacs, access to things like setting properties and undo It would still be missing a *whole* lot of things vs. CF Studio, such as link checkers, a list of variables that can be inserted, syntax colorization of the markup, etc. Let's say it moved up to a 25. --Paul Paul Everitt Digital Creations paul(a)digicool.com 540.371.6909
