If you are using python to build a zope product, the ZODB is used automagically, you don't have to do anything special. To access MySQL DBs you have to add an appropriate zope product to handle queries. A search on zope with mysql ...or vice versa returns mostly IMO embarrassingly old hits, many from old.zope.org and five to ten years old. So either the old info is still valid, or there is a lack of current information on using zope with mysql (though it is said that it is easy - where are non-stale howtos/tutorials for those who don't already know how?). Can you point me to a resource for Python and mySQL? I've bought 'Dive into Python' but it has no reference on how to use it with mySQL. If my current hosting provider supports Python and mySQL, can I make it work? They won't let me install anything on the server side though, so I can't use any modules that aren't there already. Look for info/howtos on Python's DB-API and the MySQLdb module. For example: http://pypi.python.org/pypi/MySQL-python/ http://sourceforge.net/projects/mysql-python/ http://zetcode.com/databases/mysqlpythontutorial/ http://www.devshed.com/c/a/Python/MySQL-Connectivity-With-Python/ ...though sounds like you can't add such modules on your current provider's server if not there already.

Re: [Zope] Help in deciding approach to Web App
Aloha, I think you might want a "both and" approach rather than an "either or" approach. In which case Niels' comments re the ability to use both objects/object DB and relational DB in python/zope applications are highly relevant. If you go with an object-based combination like python/zope/ZODB where you can also use/integrate relational data, then you can use each model/data approach where most appropriate for what you're building. It sounds like there may be some of both, as you describe an eventual "expert system" app. If you use PHP or most any other HTML-munging/scripting platform that I'm aware of, you are crippled in terms of using 'true' OO programming methods (useful for an 'expert system') and object DB where they are most appropriate. Especially for the size and flexibility of what you are aiming for, a 'true' OO language seems essential. In short, you don't have to do object DB *or* RDB - you can use both, if using a platform that supports that such as zope. cheers, John S.

But now I'm more confused than ever. To answer your questions - Only an expert can perform data entry for the tools, obviously. Since I have no clue how to enter data into mySQL or ZODB I have no idea what's in store for me. The ultimate goal is for the engine to become an expert system that is capable of taking inputs, learning from mistakes, scraping data from reports and from the internet, and become better and better at its predictions. The logic engine will get better and more complex as more tools are added - but once all the 'current' tools are added, the system must be able to go 'solo', with an accuracy that reaches six sigma levels. As Fernando has suggested, I will have to go with C/C++, or even my own language in the future, but that day is far off. I plan to start with 50 higher-level tools and try to build a prototype. The front-end is really very simple. The choices available for the start parameters and end parameters are pretty basic, and most of the logic happens under the hood - probably at the back end if possible. Once I've built this prototype, I will know whether mqSQL can handle scaling up (in my particular case). If not, I can confidently invest in ZODB. If I can make my position any clearer in order to get a conclusive answer either way - I'll be glad to. Thanks again for your help.

Existing tools will also have version updates. Each tool, on average, has at least 100 properties that define the tool. Some of them have as high as 1000 unique properties." How familiar are you with OOP? What I mean is, when I read your high-level description of what you want to do, I imagine objects interacting with other. In your "car wash" example I see that, for instance. Or any kind of work-flow, which is what this sounds like to me. A state machine. Each tool is an object; it knows what its properties and abilities and possible states are and can communicate them to other objects and can accept and act on communication from other objects. In that way the objects interact with one another to do whatever it is you build them to do. I'm thinking of your "car wash" metaphor. In a car wash there are a variety of elements (objects) that communicate with one another to move the car through and to wash it as it moves through. Simple example: * mechanism that pulls or pushes the car through * mechanism that sprays it with water and soap * mechanism that scrubs and wipes and rubs it * mechanism that sprays it with rinse water * drying mechanism(s) These all need to signal one another so they do the right thing at the right time. Spray (or scrub or blow hot air) only when the car is in the right place for each. If some tools can be built by adding to/extending other tools, that is an object-friendly situation, since enhancing an existing tool to make another that you need saves you having to create all tools from scratch. In the car wash, maybe the different sized scrubbers used are all made by bolting together two or more of the smallest size scrubber. Maybe in parallel, maybe in series, depends on what is needed. Maybe the same scrubber controller can have different size brushes attached to it. In short, an object - tool - is code and data that interacts with other tools (other entities of code and data). An upgrade to a tool would involve changing the code and/or data that constitutes the tool. If that introduces some new way of interacting that other tools need to also know, then you add that to those tools also. Adding more tools means coding them. If they can be based on existing tools, so much the easier (and more object-appropriate). So that's some high-level information about an object-oriented approach to what I think your project is about. Tthe flexibility you appear to need as the system grows may be problematic for an RDB. And, my bias is OO, so perhaps someone who thinks in RDB-space can describe at high level how this would look in an RDB implmentation. cheers, John S. -- John Schinnerer - M.A., Whole Systems Design - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration j...@eco-living.net http://eco-living.net ___ Zope maillist - Zope@zope.org https://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - https://mail.zope.org/mailman/listinfo/zope-announce https://mail.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Help in deciding approach to Web App
Aloha, Very briefly, from what you describe, it looks like you are dealing with large numbers of complex objects (your 'tools') that interact with each other - and with some other elements that are going through this workflow process? And a context for the process? ...not sure of that part... In any case, this looks (to me anyhow) like a very object-oriented system you are modeling so an object oriented approach and language would seem most suitable. Python is one reasonable language option; zope for the web publishing aspect of the project would fit well with that. I haven't worked with other OO languages enough to usefully compare. It also sounds to me like the web publishing is the lesser part of this...? That is, the workflow of interacting tools is the real 'app' here, a process which does not all get shown somehow on a web page...or does it? Or just the outcomes? LAMP platform is so common and cheap that it's all a lot of people know about. It can be used well, and, it is all too easy to make horrible hacks and Frankestein monster apps in PHP/MySQL. Meaning, a highly structured (yet powerful) OO programming language will support you in avoiding that. Also, for development (or just to explore if python+zope might meet your needs) you don't need any hosting, you can install python+zope on your development system and try it out. best wishes...

I am not under any time constraint. *About the App:* The best I can describe it is as a kind of expert system (but not AI) that needs to find the best workflow for a process, given a set of initial and final parameters. E.g. a 'capsule' of data must pass through many 'tools' or 'environments' to reach a desired output - something like a very complicated car wash. Let's say there are many tools that can be used at various stages in the process. I have estimated there are at least 500 tools as of now, and it is bound to grow in the future as newer tools are introduced. Existing tools will also have version updates. Each tool, on average, has at least 100 properties that define the tool. Some of them have as high as 1000 unique properties. Some of these tools are linked to each other - e.g if one tool is selected, there are only n tools that can correspond to it for the next step in the process. I also have the problem of 'matching' the tools for analysis. E.g. Tool A might have only three fixed rpms - 100, 200 and 500, but Tool B might have rpms from 20 to 2000. I'm not sure how I can construct a database without spelling out each number, as in the example above. The total number of tools needed for the process can be defined at the beginning, however, it will change as the application becomes more complex in the future. I plan to address every contingency in the process. The idea is - if the user inputs the initial parameters and the desired outcome (another set of parameters), the app must find the 'best' path - sort of like a decision tree. The best path can be the fastest, cheapest, etc. I would like the user to choose what is best for him/her. Unfortunately, parameters might change, relationships might change (but not regularly) - the 'rules' I will be using might be revised for better accuracy in prediction. I also need to track each user's path and solutions' for future reference (but no personal details except username and email address for logging in). Maybe when the app is up and running, I'd like to make it more democratic, with users contributing to refining the logic/rules involved. If possible, I would also like the app to output a graphical flowchart at the end showing the workflow with all tools grouped in an easy to understand layout. *My questions:* 1. Will the app be better served with a relational DB like mySQL or an Object database? After a lot of research I've guessed that my particular case might be better served with Python and Zope/ZODB. But I might be wrong? Maybe PHP+mySQL or Django is a better fit? 2. Can anyone provide general advice on how to go about beginning such a project in ZOPE. Which is the best place to start learning for a newbie? 3. Can anyone recommend a good shared hosting provider that supports Zope fully but is not expensive? 4. Is there a module or app that is open source that I can use to output a graphical flowchart based on the results, or will I be better served programming it from scratch with Python? I would appreciate any help in getting started. Thank you in advance. I have tried most online forums but have not good any productive answers. Most of the answers I got were pro-PHP+mySQL. Adam

[Zope] Non-management actions recorded in Undo Log
Hi, we've recently seen a the Data.fs in a few of our Zope systems grow rather fat (from stable sizes around the 100-300MB level to >3GB in the most extreme cases). On further investigation it appears that regular user page requests are being recorded in the Zope undo log - these are not object modifications that have changed the objects themselves (the modification date against all these objects is unchanged), but normal HTTP GET requests. Systems are all 2.11.0 Zope clients with Data.fs served by matching versions of Zeo. Not all of our 2.11.0 apps that are showing this behaviour, only a couple, so I doubt it's something wrong with Zope or ZEO. I'm not a Zope developer, but can anyone shed any light on the possible issues that would cause regular requests to be logged in this way?

Re: [Zope] Character display issues upgrading 2.8.8 to 2.9.8
Aloha, OK, I have now done the upgrade the "right" way, by copying add-in products and data.fs from zope 2.8.8 instance to 2.9.8 instance (on debian 4.0). I still have the same problem occurring. StructuredDocument content that contains curly quotes, curly apostrophes, and some accented (French) chars (and maybe others I haven't spotted yet) is not displaying those chars correctly (they show up as hollow block, black diamond "?", etc. depending on browser). My assumption is that something has changed in character set handling/publishing between 2.8.8 and 2.9.8. I know nothing about zope char set handling (if that's even the right term) - it's never been an issue before.

[Zope] Resolving ConflictError

The websites are still useable, as this error only occurs several times per day, out of ~100s of requests. Searching on google, however, doesn't really give me too much insight into figuring out what my next step is. I'd obviously like to figure out what code is causing the ConflictError, and how I can get rid of it and/or fix the code that is causing it. I've read enough from google searching to familiarize myself with the fs* tools (fsrefs, fsdump), but I'm not sure where to go from there.

Re: [Zope] need advice on mass data processing
Aloha, Sounds like your data case/data model is better suited to a SQL database (Relational DB instead of Object DB). Zope works with MySQL, PostgreSQL etc. via ZSQLMethods. Look into using those, with your existing data going into a SQL DB (or maybe it is already?), if you want/need to access and manipulate the data from within zope applications. Then you also have the option of accessing that data via any app/platform that can talk to your SQL DB. I have a project I am working on where a portion of the data is very RDB-type data, while the rest is more zope/object content-management stuff. So the RDB-type data will be in a MySQL DB, and, accessible through the same zope-based platform that also provides the CMS for document/object management. Meanwhile if other stakeholders now or later want access to the RDB-type data they don't have to use zope, they can use whatever they want that will talk to MySQL. cheers, John S.

That means its going to take 50 ~ 60 minutes for 11 entries. You're creating 110k instances for storing a string and two floats? If yes, that's stupid idea.

Re: [Zope] Isn't DTML more like what other frameworks do?
Aloha, Mark, Jonathan (Integic) wrote: What does matter is that DTML is very similar to RHTML (as in Ruby On Rails), ASP, etc. ZPT requires a new way of thinking. I would much rather convert RHTML to or from DTML than to or from ZPT. So I don't really get the benefit of using ZPT. The fact that no one outside of Zope seems to have created a ZPT-like solution suggests to me that ZPT, as I said, solves a problem which doesn't exist. As mentioned other frameworks use TAL/METAL (the basis for ZPT; bear in mind ZPT is a zope-specific use of TAL and METAL) - I have worked with Roundup a bit and it was a joy to see that it used TAL for template language. One major factor nobody has mentioned yet is that TAL/METAL offers much better ability to separate logic, presentation and content. By their very nature HTML-munging template markups violate this well-known (if not well-respected ;-) design principle. The WYSIWYG editor thing is merely a side benefit of markup that is both XML compliant and cleanly separates logic, presentation and content. I suspect that nobody else created TAL because it is easier to go with what one is familiar/comfortable with - HTML-munging - than to break new ground, even when the new ground is better in both design and practice. Sure DTML is more like PHP and ASP and Ruby/Rails' HTML munge and Alfresco's HTML munge and so on (whatever they're called). As my grandma used to say, if everyone were jumping off a cliff, would you do it too just because they were? ;-) cheers, John S. -- John Schinnerer - MA, Whole Systems Design -- - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration [EMAIL PROTECTED] http://eco-living.net ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] Zope 2.9 Product Refreshing
Since I never knew the refresh tab was a fragile hack, it always worked fine for me... :-) Are you saying that a "really good" solution for this is in the hands of python developers, not zope developers? In that case it seems far off, if ever, since zope is only one of many many applications using python. I would settle for another fragile hack that works, I guess. The volume of posts so far would seem to indicate that it's not a trivial topic... John S. Chris McDonough wrote: The real effort towards making a "better refresh" should likely be spent at the level of the Python interpreter. The dynamic nature of Python is the thing that allows for a "refresh" in the first place, but the implementation of Python object references limits its usefulness. The implementation of "reload" could be vastly improved by changing Python internally to allow for a sort of mark-and-sweep reload that could traverse an object graph full of references between an object and the modules that it is declared in. Anything else will likely be too fragile to work in all cases.

import MySQLdb This is probably redundant. import string request = container.REQUEST session = request.SESSION result = (context.aq_parent).selects.select_from_table() print result Assuming you want the person's name printed, change this line to: print result[0].name Think of the result from a ZSQL query as a list/iterator over the resulting rows.

Re: [Zope] question on simple_send in MailHost
Aloha, I did try send() - it seems one must know something about RFC822 message formatting to use it...? I know nothing about that, and could not quickly find any clear and concise howtos or tutorials, just verbose and confusing specs and mailing list posts and so on. I tried using send() with the same plain text body and from and to strings I was using for simple_send()...in case it might work... When the mail arrived, some of the header content was in the body and not in the header. It did arrive at all addresses in the To: field, I will admit... :-) But the header was broken somehow, I assume because I didn't know how to format it correctly. That was all the time I had to mess with it for now. thanks, John S. Andreas Jung wrote: --On 18.

Re: [Zope] ZSQL Method Question
Aloha,
I think so, for the moment anyhow!
Thanks all,

Cliff Ford wrote:
Comment on Peter's suggestion: I am no expert on these things, but it is
my understanding that for MySQL LAST_INSERT_ID() fetches the last
autoincrement value made by the current insert, so the outcome is not
affected by virtually simultaneous requests. And I don't think MySQL
accepts a value for the autoincrement key. I am a bit surprised that the
code you quote is reliable - surely there is a possibility of an insert
after calling GetNextID and before calling SQLInsert in the python code?
Comment on Tino's suggestion: I think that LAST_INSERT_ID() is MySQL
specific and I guess CURRVAL() is Postgres specific. But the principle
is the same: calling within the same Z SQL Method ought to be safe.
Anyway, I hope John has had is question answered.

I use PostgreSQL and with postgres you can always ask the sequence what

next_id = context.GetNextId()[0].next_id
context.SQLInsertUser(uid=next_id, name='Peter')
where 'GetNextId' is a ZSQL method that looks like this::
SELECT NEXTVAL('users_uid_seq') AS next_id
Its even easier:
one ZSQL Method:
INSERT INTO foo (foo_id,blah,bar) VALUES
(nextval('foo_foo_id_seq'), ... );
SELECT CURRVAL('foo_foo_id_seq') as foo_id;
But your above solution is valid too.

[Zope] Improved Zope Org Proposal
Aloha, ... >> I start to understand: >> >> You want to have a narrow, a focused site >> because you fear that a bigger one cannot be managed. >> >> In such a case, I would say: start with the small solution >> and maybe get bigger later. This is a basic principle of design that works (as opposed to design that fails to work). Start small and work the edges outwards. The "work edges outwards" that works is often modular in nature (perhaps a.k.a. 'micro-sites'). That doesn't mean it can't look-and-feel like "one big site as access point." Biting off more than one (person, organization, whatever) can chew usually results in choking... So I actually see a lot of agreement in what may appear to be argument. Also: I agree that despite the wonders of zope, the zope.org site is not as stunning a place to refer people to as it could be. For the most general public face of the site, I support the idea of a clear and simple "brochure-like" approach. A couple major open source project/product sites that I am excited about referring people to: http://rubyonrails.org http://www.mozilla.com ...and to some extent http://www.openoffice.org ...although IMO the OO site is not quite as clear and well-designed as the other two...better than zope.org though. Also bearing in mind that the Ruby On Rails site is for a development platform while Mozilla and OO are end-user app sites - somwhat different audiences. cheers, John S. -- John Schinnerer - MA, Whole Systems Design -- - Eco-Living - Whole Systems Design Services People - Place - Learning - Integration [EMAIL PROTECTED] http://eco-living.net ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] Improved Zope Org Proposal
Aloha, As an occasional user of the zope.org site I'll present my typical use case, as that's what matters most to me... :-D I go there normally for one of two reasons: 1) to slog through available products to see if I can find something to suit a development need I have 2) to slog through HowTos and documentation and tips and the like to try and solve some issue I can't figure out or learn how to do something I'm trying to do first time or differently etc. On the one hand, there is a lot of completely and nearly obsolete content that turns up in both these cases, thus my use of the word "slog"... On the other hand, I do sometimes find just what I need somewhere in all of what's there...and it's not usually easy. And, sometimes, it's somewhere in all that "bit-rot" that will no longer be supported...so I guess there will be less cruft and, hopefully, not too much less useful information in the new site? What I would really appreciate on a new zope.org site would be an improved search functionality. Something that lets me filter out all but certain types of objects would be great. If I'm searching for a product, I only want to see hits on relevant product objects or directly related objects that will clearly point me to a product (like a product review, if there is to be such a thing)...likewise for HowTos, etc. etcinstead of as now where I get back all kinds of objects that happen to be hit by my search string even when most of them are irrelevant types of objects.

[Zope] How to set selected items in multi-select list from lines property
Aloha, I have an "add" form where a user can add an object. In one part of the form, the user selects zero or more options from a multiple select list. The selected options populate a lines property of the object when the object is added. I also have an "edit" form where the user can later edit these same objects they've created. They can use the same multiple select list to change the selected options. Of course the previously selected options (in the lines property) need to be displayed as such when they first visit the edit form. So... I need to know how to display the multiple-select list in the "edit" form so that the options currently in the lines property are set as selected. I suspect there is some very slick way to do this, maybe with TAL alone...? So far I am only coming up with what seem to be cumbersome solutions that have unecessary overhead (comparing a list option with every element in lines property via python script to see if it should be set selected, and repeating for every list option)...is there a better way?

[Zope] Looking for current shopping cart product
Aloha, I am wondering if there is any current and stable shopping cart products for zope (2.7.5 is my current live version). I have a custom merchandise product for a client's business site. Retail sales are already handled via their PayPal merchant account. The retail items only need the appropriate PayPal button/form code and PayPal handles the rest. However the client also does wholesale, but not via PayPal, and wants a wholesale "cart" into which a wholesale buyer can put items and quantities to submit for review, final pricing, and shipping costs.

RE: [Zope] Zope + Apache on Quad Debian machine
Why do you want to do this? Do you believe that this is more effective or efficient than the scheduling algorithm that Linux uses? Binding an application to a single processor makes very little sense at all. If Zope really is your limiting factor, then you need to spread that load over as many processors as possible, not lock it down to a single cpu - if you do that, then the rest of the processors sit idle while waiting for Zope to respond. Read up on ZEO. Then set yourself a ZEO server up and a couple of ZEO clients, balance your requests between the two using pound, apache or squid. I can guarantee you that if your system is Zope limited, then this will greatly increase responsiveness and the number of requests you can process simultaneously - I run over a dozen dual processor machines hosting approx 60 Zope applications across them, all using ZEO - an average of 5 or 6 instances per system, we have no problem with Zope only using one processor; the applications that are across most machines (up to 10 in our largest application) are very, very fast indeed and can cope with all the concurrent users we can throw at it. Your problem is not Zope itself... you definitely need to investigate further before coming to the conclusion that binding a Zope instance to a single processor is a solution - if you'll excuse me, that's a rather simplistic view to take. I was also suggest reading up on Apache, Linux, Proxying/Caching, Clustering and Load Balancing - they're all factors to consider when developing and deploying a web application.

I'm having difficulty figuring out how to make METAL macros reusable. Is it standard practice to put macros into a common folder where they can be used by numerous different websites? I just can't get a handle on how they are supposed to be used. According to:- http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/AppendixC.stx Macros provide a way to define a chunk of presentation in one template, and share it in others, so that changes to the macro are immediately reflected in all of the places that share it. Additionally, macros are always fully expanded, even in a template's source text, so that the template appears very similar to its final rendering. This does not really tell me how they should be used.

[Zope] Help needed to simplify some code
Several months ago someone provided me with me with some sample code which did exactly what I wanted, but looking at it again it looks a little unwieldy and could do with tidying up. It consists of:- which involves parsing a file containing two fields separated by ',' eg. 001,abc 002,jkl 003,xyz The second field is just a string which appears in a selection menu, and the first is the name of a folder which contains an object called 'content' which get displayed on selecting the correponding link. I know this is not a particularly elegant way of doing it, but after looking at some TAL examples just can't figure out the right way to do it. Some help in simplifying it would be appreciated. -- John ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
[Zope] Using PUT_factory for objects outside of ZODB
I want to be able to intercept PUT requests to Zope to store objects
outside of the ZODB by storing the body of the PUT request in an SQL
database. I've written a PUT_factory external method that calls the
function PUT_ParameterFile defined below:
==
[...boilerplate Zope imports...]
class ParameterFile(Implicit):
security = ClassSecurityInfo()
security.declareObjectPublic()
security.setDefaultAccess("allow")
def __init__(self, context, job_batch_id, body):
self.context = context
self.job_batch_id = job_batch_id
self.body = body
def PUT(self, REQUEST, RESPONSE):
self.context.SQL_UpdateJobBatchParameterFile(
job_batch_id=self.job_batch_id, parameter_file=self.body)
RESPONSE.setStatus(204)
return RESPONSE
def PUT_ParameterFile(self, name, typ, body):
if typ == "text/plain":
return ParameterFile(self, name, body)
=
The ParameterFile.PUT method is being called, but then Zope returns w/
the error "Can't pickle : attribute lookup __builtin__.ParameterFile failed". Why is
Zope trying to pickle the ParameterFile object when it's handling PUT
itself?
TIA,

Hello, I have been using the Structured Document (SD) product with page templates (to provide some content sections that a client can edit using structured text).

Vision Statement ... ...where vision_statement is a SD object. I expected that this would work the same if vision_statement were a RSTD object...however it does not. What displays is only the unrendered, plain text content of the RSTD. Can I use a RSTD object in the same way I have been using a SD? If so, how do I get it to render? This is on zope 2.7.5 with the ZReST that comes "built in." A RSTD called directly (instead of inside a ZPT as above) renders as expected. thanks, John S. __ Do You Yahoo!? Tired of spam? Yahoo!

[Zope] dynamically creating zip file, returning to user
Zope 2.8.0, Python 2.3.5
I'm having a heck of a time figuring out how to zip up some files in my
zope instance and return them to the user. I can sucessfully create a
zip file on the local file system, but if I try to pass it back to the
user it is corrupted. Of course I'd rather not create this tmp3.zip
file, so if there's a way around that (which I'm sure there is!) please
do let me know.
filename = 'test.zip'
response = self.REQUEST.RESPONSE
response.setHeader('Content-Type','application/zip')
response.setHeader('Content-Disposition','attachment; filename=%s' % filename)
# tried zf =
zipfile.ZipFile( response, 'w' ) but get error, ZHTTP object doesn't
have tell method
zf = zipfile.ZipFile( '/tmp3.zip', 'w' )
zf.writestr( 'testfilename', str( self._getOb( testfileid ) ) )
zf.close()
f = open('/tmp3.zip')
return f.read()
Any thoughts on what fairly obvious thing I'm doing wrong? Thanks!

[Zope] Programmatically flushing entries from RAM cache?
Is it possible to flush a path w/ a specific argument from a RAM cache from a Python script? Here's my situation: I have a script FolderExists() that takes a single "path" argument and, after running an SQL query, returns True or False if the folder path exists or not in the database. Since the database query is relatively expensive, I want to cache its result in RAM. However, if a folder is created (using another Python script in the same Zope instance) I want to flush the cached result for the path (i.e., I don't want to flush all of the cached entries for the FolderExists method if that can be avoided).

[Zope] Mailman & Zope
How do I configure a Mailman list for a website which is Zope based? I guess some entries in Apaches configuration file need to distinguish between Zope based pages and Apache pages for a given virtual host, but I've no idea how to do this. Can anyone give me an example? -- John ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

All I'm asking for at the moment is how to take advantage of what are supposed to be existing options of setting the socket name to something other than the default 'zdsock'.

I am unable to use the name 'zdsock' so would like to configure Zope to use a user specific socket name. Either it is possible or it isn't. So far no one has told me how I can use what are supposed to be existing features. I've even found a sample.conf which contains this # Harmless example program sleep 100 # Repeat the defaults backoff-limit 10 daemonTrue forever True socket-name zdsock exit-codes0,2 # user has no default umask 022 directory . default-to-interactive True hang-around False but no one seems to know how/where this is can be used.

Zope itself works fine when started via runzope, so what is the problem in trying to provide an alternate socket name? zdctl is supposed to accept an alternative socket name:- -s/--socket-name SOCKET -- Unix socket name for client (default "zdsock") Unfortunately, I can't figure out any way to make use of this option. > Chris > > -- > Simplistix - Content Management, Zope & Python Consulting > - http://www.simplistix.co.uk > -- John ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Tres, Do you mean ? $SOFTWARE_HOME/lib/python/Zope2/Startup/zopeschema.xml That is the location of such a file on my system. As for hacking schema's that is something I'm not familiar with so I might need a little hand holding before I manage to apply the change you suggest. This section describes the options for zopectl. These options ... options, the command line option (short and long form) are given here too. The program(s) that will be run by the runner Command-line option: -d or --daemon. - call umask(022) How exactly do I hack the 'socket-name' key into the file? Would the file $SOFTWARE_HOME/lib/python/zdaemon/sample.conf be of any use in this matter? > Please submit a patch (to http://www.zope.org/Collectors/Zope) when you > get it working.

I haven't found any documentation for zope.conf anywhere and have no idea if is an acceptable keyword.
