[Zope-dev] Ids starting with _

Now, with the change to a security policy "Everything is forbidden when not explicitely allowed", the need for such a rule based on naming dwindles. Maybe, it will disappear sometime in the future.

[Zope-dev] Membership and ZPatterns
OK, so I have been playing with ZPatterns quite a bit lately. And some old (current) issues with PTK comes back to mind. Among them are: o Not all portals will want a user to have a folder o username is not changeable With ZPatterns, I believe we can solve the first one. First things first, the first one. :) Proposal: On the Membership Add form, there be an option for user folders. If set, this option would install a trigger. This trigger would then, upon creation of a new user, fire off a MakeMemberFolder (that name is just a placeholder) method that would handle the creation of their folder. Of course, this is secondary in priority to getting some user management tools available, IMO. Now, something to remember, is that the lack of a user folder does not neccesarily elminate the capability of a user to contribute to the community site information base; though that is desireable for some sites. Through use of ZTopics, ZPatterns-based Content, and ZCatalog, one can build a site that stores types of content in it's own place, and provide a variable interface, for both browsing, and user management. I am actually working on a site built like this, so I know it is do-able. :) Thoughts, Opinions?

[Zope-dev] ZPatterns design question
Let's say I have an AddressBook specialist. It stores Address records as DataSkin-derived ZClass instances (meta_type Address). The AddressBook has various methods to list the addresses, search the addresses, enter new addresses. The Address ZClass has a single propertysheet: address. When I add a new Address, a Trigger causes the AddressBook's catalog to catalog the new address. When I delete an address, it gets removed from the catalog. Let's say I want to combine my AddressBook with a Suppliers specialist. The Suppliers specialist knows about DataSkin-ZClasses called Supplier. A Supplier has its own propertysheet "supplies" that has information about the kind of goods and services supplied. A Supplier also has an address. Suppliers appear in the AddressBook. When I get a Supplier from the Suppliers specialist, I want it to have two propertysheets: supplies and address. Implementation: When I create a new Supplier, I also create a new Address in the AddressBook that has the same key (read "id") as the new Supplier. The Suppliers specialist has some sort of SheetProvider that either asks the AddressBook for the "address" sheet for a particular key, or (not so good) delegates directly to the Rack where the Address objects are stored. Bunch of questions: Is this the ZPatterns ideomatic way to do this? Can I use SkinScript to get propertysheets from another specialist? Is the SheetProvider that gets the address for the Supplier objects also responsible for adding and deleting Address objects? Do I need an Address object for each Supplier object? What kind of propertysheet should I be using? Should the method in the AddressBook specialist be returning an Address object, or just an address propertysheet? Or, more generally: Adding sheets to a "party" seems to be one of the important ZPatterns ideas. What is the best way of implementing it, using the simple case of two specialists as an example?

Re: [Zope-dev] ZPatterns design question
At 11:09 PM 7/30/00 +0100, Steve Alexander wrote: Let's say I have an AddressBook specialist. Why? :) Seriously, what is the function of "address book" in your application? Is it to find people in general? Or...? Let's say I want to combine my AddressBook with a Suppliers specialist. The Suppliers specialist knows about DataSkin-ZClasses called Supplier. A Supplier has its own propertysheet "supplies" that has information about the kind of goods and services supplied. A Supplier also has an address. Suppliers appear in the AddressBook. When I get a Supplier from the Suppliers specialist, I want it to have two propertysheets: supplies and address. I'm having a lot of trouble understanding your application. Can you tell me what you're trying to do in the problem domain? ZPatterns design is strongly rooted in the problem domain, not the programming side. The answer on the programming side is usually, "do whatever supports the problem domain." :) Bunch of questions: Is this the ZPatterns ideomatic way to do this? Dunno. Explain the problem you're trying to solve, and I'll tell you the simplest way I know to do it. Can I use SkinScript to get propertysheets from another specialist? No. I don't have SkinScript sheet providers yet. I'm not sure exactly how to make them just yet, because I haven't run into a spot where I've needed them. I hate trying to write something when I don't have a good feel for what's needed yet... :( Is the SheetProvider that gets the address for the Supplier objects also responsible for adding and deleting Address objects? Eh? A sheet provider is responsible for sheets. If you want to have the "same" sheetprovider being used for both objects' address sheet, that should work just fine. And it would be reasonable to have that sheet provider also act as a catalog trigger, if you want it to be an invariant that all address sheets are stored in the catalog. Do I need an Address object for each Supplier object? No, just a propertysheet. What kind of propertysheet should I be using? Depends on what your application needs. I can see circumstances where the best place for that sheet could be LDAP, SQL, or the ZODB. Your app's needs decide. (That's the nice bit about ZPatterns, too... you can always change your mind later, as long as you don't build in your assumptions.) Should the method in the AddressBook specialist be returning an Address object, or just an address propertysheet? Depends on what you want to do with it. Generally speaking, though, I have a hard time seeing what your addressbook specialist is FOR, unless it's just to provide a combination of general search location for anything that has an address plus a PIM-style addressbook. In which case, I think your confusion comes from terminology. I would expect to store "Contacts" or "Entries" in an addressbook, and these would have address sheets, as would "Suppliers" or whatever else. So the thing in an addressbook isn't a sheet by itself, but it's kind of confusing to be mixing address objects and address sheets. Anyway, to answer your question - I think that your getItem() for an address specialist wants to return some object with an address sheet. But not an address object. Contact, Entry, Supplier, TennisBuddy... whatever the heck kind of object it is. Or, more generally: Adding sheets to a "party" seems to be one of the important ZPatterns ideas. What is the best way of implementing it, using the simple case of two specialists as an example? Let's assume that the specialists are at different abstraction levels, e.g. "Addresses" and "Suppliers", where other things exist that have addresses, like "Customers". Customers and suppliers both have an "address" property sheet, which you want to be searchable, printable, etc. from your "Addresses" specialist. There are at least a few ways to do this: 1) Store all addresses in the same database, and implement a sheet provider which you place in all the specialists. Then create a Rack which returns generic "addressbook entry" objects from this database. (Downside: unless you store URL's in the database, there's no easy way to jump back to the "real" object from which the address entry derives.) 2) Store them in different places, but have all the sheet providers update a catalog in the addresses specialist (which takes care of the URL problem) 3) Combine 1 and 2 - use the same database for storage but use a catalog also anyway Which you select depends on your application and the things you're integrating. ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Generally, you should not write anything in the source code to zpasswd.py, unless you want to change how it works. But you know that, don't you. Jonathan, it happens often on the list that someone posts confusing questions, where people scratch their head for some time trying to figure out what the person's problem might be. This is rather inefficient, as the person does not get the answer they want, or get an answer that does not fit their problem (as the answering person did not understand it). Unfortunately, your posts fall rather often in this category. I would recommend that, when asking a question to the list, to - take time describing your problem clearly, assuming the reader knows Zope but not your application; - make clear what you want to achieve; - make clear if you either have a question how to do something, or if anything does not work as you expected; - wait at least one hour and re-read your post to verify that it is fully understandable before actually posting it; - if at all possible, have some other person read your post and ask them to rephrase your question back to you, i.e., make sure that they get your real question from your post. More work? For you, initially yes. For all together? No, a lot less. For you untilk you get an answer? Probably not, as you are much more likely to get an answer to your problem, without several exchanges back and forth. In any case, it is making better use of the time of people wanting to help you, and prevents them from just adding you to their kill file (as I was very nearly to do at some time). And it is likely to give you a better standing in the Zope community.

Zope would be used with Worldpilot, in order to provide Webmail, Calendar, to do, etc. THis demonstrates a problem or two with Worldpilot. I would defintiely _not_ use worldpilot in that setting. Why not? Well, the sharing capability (IIRC) gives a list of people on the system you can share with. Think about that for a moment. Four hundred thousand people. One list. It would be nice if it were possible for people to not appear in the list, and for there to be groups. Yes, this is a problem. As a first step, we are going to remove sharing from Worldpilot (disabling it). Then we would like to give customers the possibility to "create" their own groups and subgroups, so that they can build their own "company-on-the-web". Has anyone tried the scalability of Zope till this level ? Well, what you are describing really isn't a test of Zope's scaleability. , but rather workdpilots (and the machines's). Zope's scalability in this case is more a matter of resource usage, than a funtion of the number of users. Thats is to say, what is the expected load of the machine/site. 400,000 users will not access all at once, will they? Zope can be scaled accross multiple machines, through the use of ZEO, so if your load gets too high, you can move to a ZEO solution, adding machines as neccessary. As far as I can understand, ZEO is still in alpha/beta stage, so I am not sure to use it immediately. One caveat to that is that worldpilot stores data on the filesystem, so that data would need replicated accross the sites. Perhaps NFS or Coda could server this function. There is one more problem. Worldpilot create a directory for each user. For 400.000 users this means 400.000 directories, which is not nice for Linux+ext2 (and in general I am not sure I want a directory with 400.000 files inside). So we are considering either hacking WP, so that it creates something like a p/a/paolo directory for the paolo user, or moving data to a relational database. The latter could be the preferred solution, but it could become a too long step right now. So probably we are going to use the former. BTW, I have seen WP has the directory /var/spool/worldpilot that is hard coded into the code. Perhaps we could create a configuration file for WP, in which one can specify these directories.

Re: [Zope] Starting Zope
Interesting argument. However, consider this: if you completely trust your 'firewalled' box, then why not run the web server as root? One response, in your case is the fact that you mention your trust on users(humans are the most easy to compromise, however that argument is a bit OT). However, do you trust all of your webserver code? Do you trust your cgi-bin scripts and applications? And by trust I not only mean harmful intent by the authors of software, but unintentional bugs which can be exploited, and will be given the privilege to bind to 1024 ports even when they run as a user with least privileges.

Re: [Zope] Can multiple processes access a ZODB3 file?
As Chris already stated (many times 4 effects:) ZODB is process locked. The question than becomes what kind of process interaction do you want with the zodb. most everything can be done by having hooks into zope and interacting with those hooks from your external python process. examples are a cronned mail script that checks emails and sends them into zope, an external document retrieval system that grabs new docs and sits them on a file system or inserts into ZODB via hooks, a python zope product that gives a corba interface to selected zope objects... basically anything python can touch. if you're python process needs to be more intimate with the zodb than it might require a bit more planning. what were you trying to do? generally for external interactions i use xml-rpc (if the data sets aren't huge), but you could also script a monitor session. Kapil Ross Boylan wrote: If I have Zope running, using ZODB3 on Data.fs, can a separate process also use ZODB3 to access Data.fs? I have my suspicions, but I'm not sure. I'm interested in this because I'm in the middle of a balloting period. People email me their ballots. I will need to check them for validity, send out confirmation or error messages, and eventually tally the results. I definitely want a persistent store, so ZODB seems good. Also, I eventually would like this to be a Zope product, with people able to access the results on the web (and, in the future, vote on the web). But getting it Zoped may be too much work in the short run. So, I'll have a Zope server running on my Debian system, and another process will be going through the mail. It would be more straightforwad if that other process worked directly with the database, rather than going through Zope via http or xml-rpc or something similar. So I'm wondering if that's possible. I can always take the indirect route if, as I suspect, that's necessary. I'm cribbing from parts of the Poll product as appropriate. The polling machinery is considerably more complex though: a restricted list of voters, various muckings around to get the info out of the email, and preference voting (1 for first choice, 2 for second, etc with an instant run off). I know Zeo is more in the multi-process space, but I don't want to use it for this project because I don't have time to learn it; it's alpha; and it seems like overkill for my problem. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev ) ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] OQL for ZODB - (SQL like for objects Databases)
Its probably possible but its probably more work than you're interested in. They speak different languages a relational system is built on relations in square/rectangular tables. an object system esp. the ZODB can store objects which can be of arbitrary nature, not to mention acquistion and inheritance. a couple of pointers (maybe misleading) what you need is an object relational mapping that understands the ZODB and SQL. it depends on what you want to do with it and what kind of queries looking at your original email, this sounds most like you just want... ie to be able to retrieve objects based on properties in which case ZCatalog is the way to go. A Catalog is an object indexing system built on top of the ZODB for maintaining knowledge of objects and they're properties for fast searching/retrieval. if you really want an sql syntax to the ZODB read on but be warned getting at acquired props will require some serious work/design. you could create an inherited catalog that can layer a simple sql syntax over its searches and design it to return objects instead of references. you could also write a custom ORB that could map into the ZODB according to SQL syntax. although i haven't looked at the source. chris m's Interbase storage might be worth a look (it probably stores everything as a BLOB which might not be helpful). Other systems that might be helpful are OZONE an open source java OODBMS and Lore an XML storage with searches. Kapil E. Discors wrote Hi, Is there a tool like SQL for ZODB ?

Zope would be used with Worldpilot, in order to provide Webmail, Calendar, to do, etc. THis demonstrates a problem or two with Worldpilot. I would defintiely _not_ use worldpilot in that setting. Why not? Well, the sharing capability (IIRC) gives a list of people on the system you can share with. Think about that for a moment. Four hundred thousand people. One list. It would be nice if it were possible for people to not appear in the list, and for there to be groups. Yes, this is a problem. As a first step, we are going to remove sharing from Worldpilot (disabling it). Then we would like to give customers the possibility to "create" their own groups and subgroups, so that they can build their own "company-on-the-web". Cool. Has anyone tried the scalability of Zope till this level ? Well, what you are describing really isn't a test of Zope's scaleability. , but rather workdpilots (and the machines's). Zope's scalability in this case is more a matter of resource usage, than a funtion of the number of users. Thats is to say, what is the expected load of the machine/site. 400,000 users will not access all at once, will they? Zope can be scaled accross multiple machines, through the use of ZEO, so if your load gets too high, you can move to a ZEO solution, adding machines as neccessary. As far as I can understand, ZEO is still in alpha/beta stage, so I am not sure to use it immediately. That is stur aboiut the stage, but seems to be more One caveat to that is that worldpilot stores data on the filesystem, so that data would need replicated accross the sites. Perhaps NFS or Coda could server this function. There is one more problem. Worldpilot create a directory for each user. For 400.000 users this means 400.000 directories, which is not nice for Linux+ext2 (and in general I am not sure I want a directory with 400.000 files inside). Linux+ReiserFS ;^) So we are considering either hacking WP, so that it creates something like a p/a/paolo directory for the paolo user, or moving data to a relational database. The latter could be the preferred solution, but it could become a too long step right now. So probably we are going to use the former. I agree this is another issue of WP. Perhaps if it was modified to use ZPatterns ... BTW, I have seen WP has the directory /var/spool/worldpilot that is hard coded into the code. Perhaps we could create a configuration file for WP, in which one can specify these directories. Yeah, this is one of the my issues with WP. It just seems to be counter to the precepts of Zope and Linux to hard code this stuff. The other is that user login information is stored on the hard drive in plaintext.

Firestar wrote: Hi, I have read through(and tried out) the tutorials and Guides at Zope.org, and now eager to port my company's website over to Zope. (The website was originally programmed in PHP) In my original design, I used OOP mainly. I defined each section(e.g. News, Events, Products) as a class by itself, inheriting from a "main" superclass. Each class would contain their own set of attributes(such as font-color, title) and methods(e.g. display news headline, or display events schedule). Common attributes method that are widely used are placed(shared) in the "main" class(e.g. talking to MySQL database). So, if there's any changes or updates, inheritance will propagate the changes to the rest of the subclasses. (As usual, management will require extra features such as personalised page, membership or web-based email to be added in future. Hopefully, this kind of structure would make adding new features a breeze.) I believe Zope is based on a similar way (and much more powerful). I was wondering how shld i start something like this in Zope - i read abt ZClasses(where you can define your own Folders), Products(for defining yr business logic) and DTML(for dynamic data display). Your opinions will be much appreciated. regards, firestar My Take. zope adds enough complexity and options that they're is invariable More than one way to it. i generally do pure logic suff in base classes in python. and then setup an inherited zclass to do the display and sql stuff. i think you should also take rely on acquistion more for your sql issues. you're classes can acquire the sql stuff. try sticking an SQL folder in your root zope and call your methods dtml-in "SQL.myMethod()" /dtml-in or alternatively in the section for each class. acquistion is an integral part of zope and is pretty powerful for simplifying design and implementation.

Re: [Zope] OQL for ZODB - (SQL like for objects Databases)
Thanks to all, Having Class wine Drinker in relation. Drinker can drink (0-N) wines. Want to do a query like : MyListOfWine = wine where driker like 'Emmanuel' (Pseudo code) Is there a way to do that in ZODB ? E.D. == Le dim, 30 jui 2000, vous avez écrit : Its probably possible but its probably more work than you're interested in. They speak different languages a relational system is built on relations in square/rectangular tables. an object system esp. the ZODB can store objects which can be of arbitrary nature, not to mention acquistion and inheritance. a couple of pointers (maybe misleading) what you need is an object relational mapping that understands the ZODB and SQL. it depends on what you want to do with it and what kind of queries looking at your original email, this sounds most like you just want... ie to be able to retrieve objects based on properties in which case ZCatalog is the way to go. A Catalog is an object indexing system built on top of the ZODB for maintaining knowledge of objects and they're properties for fast searching/retrieval. if you really want an sql syntax to the ZODB read on but be warned getting at acquired props will require some serious work/design. you could create an inherited catalog that can layer a simple sql syntax over its searches and design it to return objects instead of references. you could also write a custom ORB that could map into the ZODB according to SQL syntax. although i haven't looked at the source. chris m's Interbase storage might be worth a look (it probably stores everything as a BLOB which might not be helpful). Other systems that might be helpful are OZONE an open source java OODBMS and Lore an XML storage with searches. Kapil E. Discors wrote Hi, Is there a tool like SQL for ZODB ?

RE: [Zope] Starting Zope
Not to continue offtopic for too much longer, but IMHO, the "only root can bind to ports under 1025" was, and continues to be, a terrible UNIX hack that was possibly reasonable at its time of inception, but that has since *caused* more security holes than it ever helped to prevent. The argument for the hack is backwards compatibility, any other explanation usually ends up as rationalization or circular logic.

That's what we did. Which is an even worse idea. Why? On a sufficiently firewalled off box, where the few logins are completly trusted, what's the diff? If you were worried about people cracking a user account and getting underneath telnet, than limit the lifting of the restriction to port 80. If you are concerned that non-root users could launch attacks from low ports at other machines, assuming that only good guys can come from low ports is pretty naive. The whole business about not letting anyone but root bind to low ports makes sense for a public access machine where all the first year engineering students have an account, but for a dedicated application server it is kind of misdirected. You ought to be running next to nothing but the application, and you had better trust everyone that you give a login to, and you out to have the thing locked down/firewalled well. So the tiny bit of possible protection may not be worth the hassle/risks of writing your own suid-wrapper, or the complexity of having a redirect and messing with site-access so that the port numbers in the zope -- what it is that parameter -- base or whatever, comes out write. Just for fun - does NT have the same restriction? Nitesh Dhanjani wrote: Interesting argument.

[Zope] Python/Zope API
Hello folks. I want to be able to render Zope objects from my python external method/product. Idea is to use it to render parent object. Here is code I came up so far with: def view(self, REQUEST): if self.meta_type == 'Folder': doc = self.aq_base.index_html(self, self.REQUEST) else: doc = self.aq_base(self, self.REQUEST) return doc It does return rendered parent object, but I have some questions and probably request for improvement ideas :) 1. The whole thing becomes broken with SiteAccess. Complains about premissions/PhysicalRoot (AFAIR) 2. Are there ways to improve it? For example I would love to know how you can check if you can actually render an object. (For example you can not render Control_Panel). Possible use for it (to make the whole idea a bit clearer) /index_html (some stuff in it) /view (above code in external method) /index_html/view returns rendered index_html doing some magic with HTML/whatever is in it (for example encrypts it with public key, strips down carriage returns/tabs/spaces etc...) In other words acts as a filter.

Acquisition is very similar to inheritance, in that it deals with the sharing of namespaces. After that, it starts to become a little more complex.
