Re: [Zope] newbie question: parameter passing for ZSQL Object
With dtml-call insertItem, Zope gives me following error message: If the parameters are from another SQL statement, then the SQL method will not find them, since not the entire namespace is sent. Try: dtml-call "insertItem(param1=pvalue1, param2=pvalue2, param3=pvalue3, param4=pvalue4)" pvalueX can be also a variable. If your variables are called paramX, then the following will work: dtml-call "insertItem(param1=param1, param2=param2, param3=param3, param4=param4)" That is typical Python syntax. So in case you want to know why and how that works, read a little in the Python documentation (which is btw excellent.)

Re: [Zope] ANN: Perl For Zope
I have kept silent on this issue while watching comments fly by. I'll agree with a comment Paul made about passions being high and that can be a good thing. Disagreements are sometimes inevitable, however we do not have to be disagreeable. It seems that many here who do not share the concerns of others have left technically arguments and gone on to calling others childish or silly. It is reasonable and understandable that you may not agree with them. However to resort to such behaviour is below this community. I hope the concerns expressed by many here do not happen. However, that does not mean they can't. I like many here chose Python then Zope. I chose Python not Perl. What is taking place here and has caught many in the community off guard is somewhat of a change in what Zope is. Some have expressed that Zope is already multilingual. That is true to a certain extent. But Perl does not add to Zope capabilities that Python does not have. (IMHO) In this perspective it does not add to Zope. Python, DTML, SQL, XML, XML-RPC, XSLT, etc. are not equivalent languages. They have different scopes and capabilities. Python and Perl are reasonably equivalent in capabilities and it boils down to personal preference on the choice. This brings us back to a change in what Zope is or what Zope has been seen as. This provides an opportunity for DC and the community to really define what is Zope. This discussion needs to clarify what Zope's definition is. This will promote greater understanding and reduce misunderstandings. To this point in many peoples minds Zope has been defined as being Python. This changes things. Yes I understand Zope itself is built in and will continue to be built in Python and C. This is a paradigm shift for many here. Once this settles down, I hope this community will be stronger for it.

[Zope] Deprecation of dtml-var ?
I've noticed that just about every new Zope user gets bitten by dtml-var foo == dtml-var name="foo" and dtml-var "foo" == dtml-var expr="foo". Messages reflecting this confusion come to the Zope list frequently. Everyone appreciates the shorthand, and everyone does eventually learn the difference between dtml-var foo and dtml-var "foo". Perhaps it would be better to use dtml-var name="foo" and dtml-var expr="foo" more often on the list for the sake of newcomers? Or perhaps there should be a whole (but short) chapter in the DTML that is nothing but boldface "dtml-var "foo" is actually running a python expression". Or, how about a dtml-expr tag (which could even start out as a simple synonym for dtml-var) so that people won't be confused about what is python and what is a variable lookup with the special calling properties. I think DTML is quite nice and works very well, but I see a lot of people get caught on this, and almost anything that can be done to remove the barriers of entry to Zope is a good thing.

If this approach would let users email content into things like the PTK, or more generally to create Zope objects by emailing content to an address that corresponds to a Zope method or object then that's what I'm on about. Archiving mailing lists shouldn't be a big issue since there are already Zope mailing list archives that are searchable in ways currently more powerful than ZCatalog has to offer. Note that no mailing list software I know of tries to be an MTA. With sooo many different implementation issues, making zope an MTA would be a big challenge, IMNSHO.

Re: [Zope] ANN: Perl For Zope
Are Python Products considered implementation level? Or another question. What are the current reasons that Perl Products are a no no? Where are the lines for having other languages being first class citizens of Zope without them being "implementation languages"? I think this also goes back to and begs the question of what is core Zope and what is built upon it? This somewhat could be answered by the modularization of Zope and it's companion packages. Just a couple of questions to hopefully clarify things. Jimmie Houchin Paul Everitt wrote: Bill wrote: [snip stuff about Perl's OO model] It's funny that you bring this up. One of the really interesting things about this project so far is learning about Perl internals. You're description is, apparently, pretty accurate. However, the way we've done this mitigates the issue in two ways. First, Perl doesn't need objects to fulfill its job. Functions are bound to the object system. All the real stuff (persistence, transactions, etc.) is in Zope (read: Python). Honestly, the goal really _is_ to make Perl a scripting language for Zope, not an implementation language!

[Zope-dev] Zope view as object file system instead of web content management
Hello DC: It have been pointed out that zope is an object file system instead of an web content management system. But the current activities of zope usage have been mainly apply it as an web app server. This point of view may not release fully the potentials of zope. We have currently seen perl is being introduce to zope, I think this is just an start: more and more people will join in to use zope with their native language. However, the current zope status is not suitable to accept such an change, I shall say we should have something like DOM for xml for zope before we can invite them to explore the world of zope. 1, zope should based on unicode, having everything look at them as if it serve their native encoding by translating encoding during the publishing machanism. 2, zope should be prepared to meet the distribution world where multiple zope co-operative is possible. I can see the benefit to have unique zope object id by having a auto-gen local zope id and together with system identifier to form globally unique id. This will benefit many things: storing object to database, transfer them, archive, tracking their changes, etc. To solve the mirror and duplicate copy, the new objectid shall take the original id, plus the duplicate type and the new system id, to preserve link and unique id. 3. some zope object can be float around without a fixed location, this can be view as all of them are located in the root location or been placed to under a transparent folder. This make no big different but can free our way to utilize objects. 4. some interfaces of creating, modifing, publish through various protocol, access to meta data, attach method, make invisible (delete), duplicate, changing its storage method, spliting version, and such can be defined as what DOM does. 5. Make the publishing machenism forgiving by nature, i.e., one can access an object by putting before it some non-exist path, as if it were located in an non-existing location. This does not change many thing, but will give greate flexability to what people can do. 6. Map dtml to the new DOM model and let everybody happy using their own native language. I am not a programmer but I feel that the current zope have been very confusing with too many surprise in dtml and its syntax.

[Zope-dev] Zope 2.1.6 minor ZCatalog bug?
I have a ZCatalog object in Zope's root folder. Its ContentView uses absolute URL's to reference its objects: e.g. "//acl_users" rather than "/acl_users". Such URL's cause a browser to interprete the first URL part as host. In the above case, it looks for host "acl_users" which, of cause, does not exist. The following patch fixes the problem in my case. It might, however, introduce other problems if the ZCatalog is not in the root folder.

Re: [Zope-dev] Memory 2.1.4-2.1.6 a.k.a. how to get objects out of the cache
All, I also am having severe problems with memory creep. Our problem exhibits itself by quickly using gobs of memory and requiring a zope restart after about a day and a half at about 100M resident. First our configuration: Core Components: FreeBSD 4.0/FreeBSD 3.4 - on separate machines of course Postgres 6.5.3/Postgres 7.0(fixes some memory leaks) Python 1.5.2 Zope 2.1.4/2.1.6 have tried both pcgi with ZServer Apache w/mod_ssl 1.3.9 and 1.3.12 Products: ZPySQLDA SQLSession GenericUserFolder I have looked at a lot of different things. This includes: Installing the gc(garbage collection) python package - Neil Schemenauer's patches Installing Postgres 7.0(fixes some connection memory leaks) Tracking the cache cleanup inside zope Tracking thread locking inside DB.py, Transaction.py Results: gc python didn't help alleviate the problem Postgres 7.0 instead of 6.5.3 didn't help the problem I do see GenericUserFolder and SQLSession objects with the Control_Panel_Debug screen, and they do not seem to go away. I wrote a simple python script to do nothing more than authenticate (log in) using the GenericUserFolder method docLogin. The memory usage quickly grows out of control. After waiting 15 minutes(my cookie timeout), no decrease in memory usage. The objects are still in the cache also. Restarting zope clears everything up, and starts out nice and clean again. We have a cron job doing this right now. Questions: 1. How does a user's connection resources etc. get cleaned up by Zope after a cookie timeout? Do I need to do this myself? 2. How does a genericuserfolder's set of objects used by an authenticated user get cleaned up. I can't seem to make those objects get reclaimed by the system, even when the user logs off? 3. I am not explicitly removing SQLSession objects. Will my usage counts for these objects remain 1, thereby never allowing them to get cleaned up, and thereby keeping my usage counts for genericuserfolder's 1? 4. Since GenericUserFolder inherits from Folder objects, is it possible that the reason my memory grows so fast is that Zope does not release the resources used by a user properly, during an abrupt disconnect? I will assist/help trying different things to try to solve this problem! thanks. eric. ___ 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 )

[Zope-dev] Case Insensitive TextIndices
Since www.zope.org and classic.zope.org (not to mention digicool.com) all seem to be down, I'll dump my feature request here (although given the lack of mail this morning, maybe mailman is down too ;-) Could it at least be an option, my view is that it should be the default option ;-), for text indices to be case insensitive... It seems crazy to me that a search for 'Fishing' will not return objects containing 'fishing'.

Okay, I get the joke now :-) * "persistent" references are effectively required to be immortal: it is _mandated_ that one be able to stringify the IOR, copy it to a piece of paper, put the paper in a bottle, and cast it on the waves; whoever opens the bottle should be able to transcribe the IOR, reify the reference from the string, and communicate with the object (which may be an entirely new "incarnation" created just for this request). This is the sort of persistent reference I meant, it's one of the reasons I like CORBA as a model ;-) A general-purpose, persistable reference in Zope pretty much has to be represented as an absolute containment path I don't agree. What happens when you move an object? The object doesn't change so why should its persistent reference? In a similar way, what happens when an object moves between storages? I reckon it should have the same POID... A man with one watch knows what time it is; A man with two is never sure. That's not quite what I meant... An object is unique. It's aquisition context may give it more attributes to play with, but at the end of the day it is a seperate entity. This entity should have a unique, global identifier; it's POID. I think putting a path in front of this identifies the context, but doesn't really do a lot to identify the object. I guess my view depends on _data_ being stored in the object rather than acquired. Is this the case? cheers, Chris ___ 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 )
[Zope-dev] Re: [Zope] newbie question: parameter passing for ZSQL Object
With dtml-call insertItem, Zope gives me following error message: If the parameters are from another SQL statement, then the SQL method will not find them, since not the entire namespace is sent. Try: dtml-call "insertItem(param1=pvalue1, param2=pvalue2, param3=pvalue3, param4=pvalue4)" pvalueX can be also a variable. If your variables are called paramX, then the following will work: dtml-call "insertItem(param1=param1, param2=param2, param3=param3, param4=param4)" That is typical Python syntax. So in case you want to know why and how that works, read a little in the Python documentation (which is btw excellent.)

Our problem exhibits itself by quickly using gobs of memory and requiring a zope restart after about a day and a half at about 100M resident.

I wrote a simple python script to do nothing more than authenticate (log in) using the GenericUserFolder method docLogin. The memory usage quickly grows out of control. After waiting 15 minutes(my cookie timeout), no decrease in memory usage. The objects are still in the cache also. Restarting zope clears everything up, and starts out nice and clean again. We have a cron job doing this right now. This seems to dovetail with the reports of SQLSession being a memory leak source.

[Zope-dev] Cataloging LocalFS content
Dear Zopistas, I think, cataloging "LocalFS" content would be nice. I have the following problems with it: 1. "LocalFS" defines various meta types: "Local File System", "Local Directory" and "Local File". Only "Local File System" is a "true" meta type which should appear in the available objects list of ObjectManager's. However, I may well be useful, to select the others, too, in for "find" and cataloging. 2. ZCatalog uses "bobo_modification_time" in its meta table and for indexing. For "LocalFS" content, this is not the best modification time to use for indexing. It would be nice, if "bobo_modification_time" could somehow be synchronized with the object's modification time in the file system. Can you give me some ideas how to best solve these problems.
