Can you get a pdb.post_mortem prompt at the actual ZODB/serialize.py:416 error or only at transaction/_transaction.py:267 where some sort of previous error is handled? yes, i put the post_mortem around the "transaction.savepoint" call at line 559 of Products/ZCatalog/ZCatalog.py. this is the place where the error is happening, but it's where the subtransaction threshold has been reached, so IIUC the error could be caused by any of the objects in the subtransaction. If the former, I often find it informative to step up to ZODB/serialize.py:407 where obj.__getstate__() is called and find out what obj is. Is it the same object every time? If not, is it of the same type every time? right. as long as the subtxn threshold number is the same, then the object is the same. but if i change the subtxn threshold, then the object will be different. as i said, i even tried reducing the subtxn threshold to '1', so, assuming my understanding is correct, this would be triggered after every object. it took many hours to get to my debug prompt; when i did, the obj was FileAttachment object that didn't seem to have any problems. i was able to interactively index the object from the pdb prompt, and even commit the transaction, w/ no problems. A next step can also be to put a pdb.set_trace() at transaction/_transaction.py:340 in the register() method such that it's is only called when the offending object is added to the transaction. i'll give this a shot, thx. Hope some of that helps, even just having someone to discuss it with is helpful, for my sanity at least... ;-) thx. -r ___ 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] help debugging a "can't pickle" error deep within a catalog reindex
hi,
i'm trying to perform a ZCatalog.refreshCatalog() on a catalog with over
29,000 indexed objects. it churns for a good long time, and eventually fails
with a long set of tracebacks, of which i've included a sample at the end of
this message.
i think i understand the gist of the issue... it's trying to write an object
(probably a CatalogBrain) to the database, but this object's __dict__ contains
a value that is of type instancemethod, which isn't allowed for persistent
objects.
the problem is that i can't figure out which specific objects are causing the
problem. i've used pdb.post_mortem to get a debug prompt way down in the
traceback, but the code goes in and out of C modules, so i'm missing a lot of
what's happening. and when i interactively peek at the objects that are being
indexed when the error happens, there doesn't seem to be anything wrong, and i
can index the objects w/ no problem. i've even tried dropping the
subtransaction threshold down to 1, so it will try to commit a savepoint after
every object, but none of the objects being indexed seemed to have any problems.
i CAN verify that the instancemethod that is causing the problem renders like
this:
/session_data_manager>>
even that hasn't proven enough for me to concretely identify the source of the
problem, though.
i've been working on this for a full day already, and am not sure how to
proceed. does anyone have any debugging tips that might help me figure out
what, exactly, is causing the reindex attempts to blow up?
thanks!

I have installed zope on both FreeBSD and various linucies and here is what I have observed: 1) Freebsd ports collection is an easy way to install zope -- the ports maintainer takes care of making the build files to handle all the zope dependencies including python versions, libraries, etc. However, I have yet to use portupgrade to apply security patches to zope instances running on freebsd. Does anyone know of using cvsupdate for getting security patches works over the ports collection of zope smoothly? 2) I've run zope on Red Hat and Suse linux. In both cases I found that I needed to install a different version of python than the one packaged with the distro becuase Zope had specific dependencies for new versions python. Applying patches to zope is manual. It has always been very inconvenient to build python and PIL in a separate run instances for zope. This seems like a major pain in the ... i've been most happy w/ debian or ubuntu, and have also had good luck w/ gentoo. in each case, i use python (as well as nearly all python dependencies, e.g. PIL) from the distribution, but then build Zope itself from source, either a checkout or a tarball. -r ___ 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] Re: Presentations Available
Nick Davis wrote: Hello Some thoughts : - Upgrading to Zope 2.8 without reading the release notes. I followed the release notes but this didn't fix catalog errors. I am not the only one. This is apparently fixed in Zope 2.8.2 but that doesn't look like it can be downloaded yet. in some cases the problem will go away if you simply execute a 'len(catalog)' command, either from a script or from zopectl debug. YMMV. - Third party products that are not yet fully compatible with Plone 2.1 and/or Zope 2.8. Should this perhaps be the other way around? If those products used the APIs correctly, perhaps a new release of Zope/Plone should still support old APIs and/or deprecate them gradually and with warning? This is a difficult problem to address but sometimes it may be better to hold back on releasing something new if it causes things that depend on it to break. On the other hand I can understand peoples desire to release something new and cool (even if not quite ready) . ;-) And its hard to know quickly what the bugs are if you don't release it to the real world. So hard to know what to do.. the problem is not with the APIs... those we have taken care to deprecate. the problems lie within template code (such as the problem you describe below), where it's much harder to maintain backward compatibility and still move forward. - Sites that have customized parts of Plone they shouldn't have touched in the first place. This is an important issue. It is difficult not to touch things that one shouldn't. A trivial example - If you want your breadcrumbs to just list the breadcrumbs instead of say "you are here" you have to copy across global_pathbar.pt and take out "you are here". There is not another easy way to do it that I can see. If you then migrate to 2.1, that .pt has changed so you have to copy the new one and re-do it otherwise nothing renders. If you want to add another logo on the right of the header you have to hack Plone's templates further. Each change is in itself trivial but they add up and when you migrate, you;re left with stuff that doesn't work and spend quite a while resolving it. And thats for those of us savvy enough to use the filesystem. Those who customised through the ZMI will have a bigger headache. tres responded to this more eloquently than i'd be able to... as for the broken products, that is a pandemic within the open source community, hardly unique to plone. True. AT's problems are entirely recognized by those of us who use it heavily, and i can assure you that the AT developer pool has no intention of continuing to pile more cruft on top of a shaky stack. . the first iterations of this will probably also have some warts. but please don't assume that plone/AT developers don't see the same problems that you see, and that they aren't willing and able to learn from their mistakes. It would seem Archetypes has improved over time. My real worry is when we do have a new release of Plone sitting on top of Zope 3 we'll have a whole new set of bleeding edge code sitting on top of other bleeding edge code, while stuff that did work with a mature AT1.3.x (or 1.4.x or whatever) suddenly stops working. Hopefully this will prove to be an unjustified fear! as tres said, z3 isn't really bleeding edge any more. i'm not saying that there won't be migration bumps.. i expect there will be. but there are a lot of folks with a lot of working code dependent on this stack, and we'll all be working together to get to the next level. Probably this is no-one's fault. It is the nature of open source. To compare, have to admit I tried to get Bricolage to work a while back, and ran into CPAN dependency hell. I wonder if perhaps the real problem is trying to do so much with so few resources. this is, to me, the crux of the problem. there are a million things that could be better. i've got far more ideas for improvement than i have the time to give those ideas... we've all still got to get billable hours in. that being said, things are getting better with time, and i expect them to continue to do so. Linux has a very mature platform as much of its base, and a lot of commercial support which helps. Perl and the CPAN is quite mature now and also had quite a lot of commercial support. The good thing about commercial support is people being paid to do grunt work and run loads of tests and update documents. Both Linux and CPAN are very modular. It is relatively easy to change one part without knowing about other parts. I think it would be easier to find someone who could patch a broken CPAN module, than someone who could delve inside Zope and Plone. This is because many of us don't understand the various components of the underlying architecture, and a lot is changing for Zope 3. Also many Perl modules are widely used by many applications, whereas a lot of Zope code is only used by other Zope code. again, tres
[Zope] Re: Presentations Available
Chris Withers wrote: Nick Davis wrote: there seem to still be migration problems and broken products which prevent people going to 2.1 yet. Yup. this strikes me as a bit unfair. to quote stefan holek from a post on plone-dev earlier today, most reported migration problems are due to: - Upgrading to Zope 2.8 without reading the release notes. - Third party products that are not yet fully compatible with Plone 2.1 and/or Zope 2.8. - Sites that have customized parts of Plone they shouldn't have touched in the first place. - Plone Team stupidity. thus, while it's true that we have made mistakes (and will continue to, no doubt), most of the problems are issues beyond our control. as for the broken products, that is a pandemic within the open source community, hardly unique to plone. how many zope products are out there of dubious quality, or that are poorly maintained? whenever you get a large community of developers, you get a mixed bag of talent and of follow-through. the suggestion you make in your talk of having a peer rating process for add-on products is a good one, certainly, and one that's been discussed before, but getting there takes some effort. My colleague has spent a long time trying to migrate a Product he wrote, from Archetypes 1.2.5 to 1.3.4, due to the fact he had to hack around problems with references. Archetypes is the chief sinner in all of this, I'm afraid. It's trying to solve a very difficult problem, and one which needs tackling with structure and upfront and intuitive design rather than the organic tacking on of new "bitz" whenever anyone felt like it that AT has suffered through... My fear is as more features are added, what you describe as a shaky stack of complex fragile components will get ever more dependencies and therefore ever more complex and fragile. Yup. yes, AT is in many ways a mess. but, as you say, it's tackling a very difficult problem, and, like most attempts at tackling difficult problems, the first iterations were somewhat less than perfect. the same can be said for zope itself... there's a reason z3 was a complete rewrite. AT's problems are entirely recognized by those of us who use it heavily, and i can assure you that the AT developer pool has no intention of continuing to pile more cruft on top of a shaky stack. instead, we're looking at how we can break the framework apart into components that can all be glued together in a nice z3 fashion. there are a great many tools available to us now that were not available when AT was originally developed (adapters, events, views, etc.), and we have every intention of making use of them to improve the stack (by making it leaner and more efficient, NOT by adding features willy-nilly!). ideally, you'll be able to pick and choose from the various AT features, using adapters to glue the functionality you need (and only what you need) into your own products. the first iterations of this will probably also have some warts. but please don't assume that plone/AT developers don't see the same problems that you see, and that they aren't willing and able to learn from their mistakes. -r ___ 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] More TM ideas
Following up to my note from yesterday. ZEA *is* the official registrant (but not legitimate owner) of the Cirlce-Z-Zope (CZZ) mark in many countries in the Madrid Protocol. You can search the WIPO database for "Zope" and find it. Zope Corporation is the official registrant of the word Zope in many countries in the Madrid Protocol and our registration predates the ZEAs. Since the ZEA registration is based on the word Zope we believe that an official trademark opposition will be successful. We are also only willing to pay the fees that Zope Corporation would otherwise have had to pay to register the marks itself. This offer was made in writing last Friday. The subtle but important point is that ZEA seems to be willing to transfer the marks to the Zope Foundation not Zope Corporation. This seems to be the essence of the difference in our position. If this is inaccurate -- i.e., ZEA is willing to transfer the marks to ZC with no strings attached then we can chalk this up to some incredible communication issue and can certainly move forward! It seems that the prospect of Zope Corporation's unfair (and unprecedented) management of the marks is the real issue. So that our position and policy are clear: *** We will not use (nor allow our successors or assigns) to use the Zope trademarks in non-competitive ways. *** The challenge is to figure out how to get this in place. One idea might be to make the BoD of the Zope Foundation the arbiter of any revocation action ZC might take. This would be a contractual relationship between ZC (and its successors and assigns) and the ZF. If ZC felt that a given ZC-licensed use of the marks had become inappropriate we would move to revoke the trademark license. If the license holder was unsatisfied with the revocation they would appeal to the Zope Foundation which, on vote of a supermajority of the BoD could overrule ZC's revocation action. It is our heartfelt sense that Zope Corporation is more likely to defend (within guidelines and process) the marks than a volunteer-led Foundation. We have heard comments that suggest that the Foundation should not be in the business of enforcement. Enforcement is an active responsibility. Perhaps once (and while) ZF has full-time staff to pursue Foundation business (including TM matters) the Foundation would be the first stop for tm issues. It has been reported that ZEA's original registration of the marks was defensive and done in an effort to preclude registrations from being made by unfriendly parties. We find it simply surprising that the first mention of their registrations to us was 18 months (!) after the fact. ZEA does not represent the entire Zope community in Europe (nor do they claim to) and certainly don't represent the global Zope community. In fact, we should all recognize that the ZEA competes with non-ZEA companies on proposals. That's fine, expected and natural. However, any action on ZEA's part that was made on "behalf of the community" is inappropriate. ZC does not claim to represent the whole Zope Community either. We are asserting our ownership (and, we think) aggressive desire to manage the marks and brand in a vendor-neutral way. With respect to ZEA's ownership of the Plone trademark - I am told by two people that ZEA helped register the Plone mark as a service to the Plone Foundation and that it has been or is in the process of being transferred. Presuming this is true I stand corrected. Even this morning the WIPO database advertises ZEA as the registrant of record for the mark.

[Zope] Zope Foundation Update
Foundation Update This note updates progress on forming of the Zope Foundation. To remain transparent as possible, we are communicating in as timely a manner as possible. First, we have contacted the Software Freedom Law Center (SFLC) which specializes in the formation and maintenance of the legal structures that support open source software. From our first conference call with our primary POC there (who also helped with the Plone Foundation), we took away some homework items including: (1) draft trademark license agreement between Zope Corporation and the Zope Foundation (2) draft/initial set of ByLaws and related formation documents that capture the spirit of what we've been discussing for a while now (i.e., Eclipse Foundation-inspired membership and Apache Software Foundation-inspired operations). We have made progress on (2) but stopped when we discovered a trademark violation that needs to be addressed before Zope Corporation can properly license the trademarks to the Zope Foundation. During my stay at EuroPython I learned that eighteen months ago (and without Zope Corporation's knowledge or consent) Zope Europe Association (ZEA) registered a trademark consisting of the Cirlce-Z (the stylized Z surrounded by a circle) followed by the word ZOPE (hereinafter "Circle-Z-Zope"). The mark they registered is identical to the corporate logo used by Zope Corporation. In the three weeks since learning of ZEA's illegitimate registration of our marks we have tried diligently (but unsuccessfully) to get ZEA to unconditionally transfer the rights of the registration. We have offered to reimburse the registration fees paid by the ZEA to the WIPO (World Intellectual Property Organization) in order to facilitate the transfer. We have further offered to preserve their license to use the Zope mark in the conduct of their business as an association of Zope companies. ZEA's registration represents an abuse of registration and management of international trademarks and the misappropriation of a mark that is clearly the property of Zope Corporation. We are sorely disappointed that ZEA is unwilling to transfer the marks quickly and quietly so that we can proceed swiftly toward the formation of the Zope Foundation. We know that the establishment of a fair trademark license for the entire Zope community is an _essential_ component of the Zope Foundation. It is possible that we will come to a conclusion with the ZEA prior to the conclusion of a trademark dispute process. However, as a result (and unfortunately), until this matter is resolved using the established legal/trademark management processes, we are not able to proceed with the Zope Foundation. We will keep the community updated as milestones are reached, so that you know what the new target dates are for the formation of the Foundation at the same time that we do. We recognize that there are lingering questions about the trademark and our management thereof. We have captured our position on these marks in an open letter to the Zope Community. You can find this letter at: o http://www.zope.com/about_us/legal/ ZopeCorpTrademarkManagement_OpenLetter.html As an aside, the ZEA has also registered the Plone logo as a trademark. It is not our business, but came as a surprise to us, that the Plone Foundation is not the owner of the Plone trademark. -- Rob Page V: 540 361 1710 Zope Corporation F: 703 995 0412 ___ 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] TAL and Javascript
Thanks to all the responders. It gave me some ideas, but alas no luck. To clarify, I am not trying to do everything in one request. Request one generates the page, a user event (selecting an option from a form) fires another request via javascript. like: And then a user event (onChange) calls getFormats. Even with generating the script with a Python script or DTML, the problem remains (for me at least) to get a value from the DOM passed as an argument to a Python script that queries my database. If my Python script didn't take an argument, I'd have no problem. I could do this and use javascript to build the select options from the appropriate values. But I'd like to cut down on what the browser has to handle. What the user chooses in the first selection can reduce what they get to choose in selection two from 3000 choices to hundreds. I'd prefer to have the backend reduce the result set rather than having the browser do the work. I thought about AJAX (no experience), but given time constraints, looks like I'll have to load everything on the page and go from there. Rob Yahoo! Sports Rekindle the Rivalries.

[Zope] TAL and Javascript
I'm stuck this, and would appreciate help or pointers.
I have a form with 2 selection drop-downs. I want the user's choice of
select 1 to drive the options displayed in select 2. When the user
makes a selection in select 1, onChange calls a Javascript function
that should write select 2 options based on the result of a call to a
Python script, passing the select 1 choice as an argument to the Python
script.
But: I cannot get the Javascript var into the namespace that the TALES
expression knows about.
Example:
function makeDropDown() {
var widget = document.getElementById('select1');
var choice = widget.options[widget.selectedIndex].value;
var data = [result of calling Python script 'foo(arg)' with
arg=choice]
// create options for select 2
}
[various html...]
[options...]
I've tried with multiple scripts, where one has tal:content=... but
cannot figure out how the TALES expression can get at what my
javascript gets from an event. I haven't done much with JavaScript
inside Page Templates, so perhaps I'm going about this all wrong.
TIA,
Rob

[Zope] Zope Corp and Z3ECM
Zope Corporation is delighted to announce its active participation in the Zope 3 Enterprise Content Management project recently organized by Nuxeo and joined by a number of community members. It's clear that the Zope Community will benefit from a consolidation of common patterns and their implementations in order to grow Zope's market share and we are excited to participate in this effort. In conjunction with the Zope Foundation we expect the Z3ECM project to set the example for global collaboration on sophisticated content management functionality and its application. We are looking forward to launching the Foundation with community involvement so that the Z3ECM project can safely share in the Zope brand. We would like to sincerely thank all of the pioneers who planted the seeds for this effort at the recent sprints (Castle, Paris, etc.). We know from first-hand, large-scale commercial experience that Zope 3 will excel at supporting this effort. Zope Corporation has been making substantial investments in Zope 3 evolution and associated add-on componentry for the last year. An example of this investment is the XML Process Definition Language (XPDL) support that is now available in Zope 3. XPDL support is the first in a series of substantial, customer-inspired contributions that Zope Corporation will be making to the ZECMP over the coming months. Together with Nuxeo's significant ongoing investment in CPS (the Zope 3 version of which will also be contributed to the Z3ECM) we expect the platform will quickly evolve to be the world-leading content management platform. We also propose a name change to the project from Z3ECM to Zope Enterprise Content Management Platform (ZECMP). This will allow the project to disassociate from Zope 3 (it seems likely that there will be 2.8/"5" ports of many/most capabilities). It also makes for a natural transition to the Zope Foundation when that's available in the early Fall. Thanks again to everyone who has helped get Zope 3 and these ideas to this exciting point!

[Zope] ANNOUNCE: Zope Foundation
Zope Corporation has begun the process of creating a Zope Foundation. The Zope Foundation will provide a mechanism for managing the various Zope projects (e.g., Zope 2, the Zope CMF, Zope 3, and other Zope community projects) in a vendor neutral way. The Foundation will have global copyrights over the Zope source code (to include Zope 2, Zope 3, and any other projects managed by the Foundation) as well as a limited, world-wide, non-exclusive, irrevocable, perpetual license to use the Zope trademarks (i.e., "Zope" and the "Circle Z") to brand its software releases. In addition, zope.org will be operated and maintained by the Foundation. The Foundation's governance mechanisms are being developed by taking the most appropriate ideas from other leading open source projects. These mechanisms are being developed and legally reviewed. We will launch the Foundation by or before the end of October 2005. We have scheduled an IRC session to answer questions from the community about the Foundation. IRC Session Summary: - Who: Zope Corp and Zope Community - What: IRC session to discuss the Zope Foundation - When: Tue, 21 Jun 2005 10a - 12p (US EDT) - Where: irc.freenode.net #zope Please send specific questions to: mailto:[EMAIL PROTECTED] We hope to see you there!

[Zope] Property id clashes with object id?
I just observed something which I really wouldn't have expected. If I set a property on an object, via a PropertySheet, I then cannot add an object of the same id at the same level (and vice-versa). Say I have a folder, to which I add a property named 'draft'. Then I try to add any object (Page Template, whatever) with an id of 'draft' inside the folder. This fails with OFS.ObjectManager.checkValidId complaining that the id is already in use. Is this how it's supposed to work?

In a manner of speaking, yes. That is, Apache needs to have correctly configured VirtualHost directives to handle the requests from the outside world appropriately, and Zope needs to have the SiteAccess product installed with correctly configured SiteRoots and access rules. It takes a little bit of time to figure out, but it works like a charm and is really quite simple, once you wrap your head around it. There's a great HOW-TO on this at http://www.zope.org/Members/anser/apache_zserver.

[Zope] Second Try: Zope FTP tunneled through SSH1
Nobody picked up at all on my first post of this question, so I'm hoping I have better luck this time. Does anyone out there even have any leads for me in this situation? Here's the repost: I'm trying to tunnel FTP connections to a Zope server through SSH1 to ensure that passwords don't get sent in the clear. (I know the session will still be unencrypted; that's okay for now.) I've followed the instructions for doing so that are available at http://www.employees.org/~satch/ssh/faq/ssh-faq-5.html#ss5.6, and doing so I can successfully create an FTP session through an SSH tunnel. The problem is, once I've logged in, Zope won't let me do anything. It responds to every valid command with a single word: 'Unauthorized.' I know I'm connected to the server, because 'cd'ing into a nonexistent directory gives me a 'No Such Directory' response, byt 'cd'ing into a valid directory gives me th 'Unauthorized' response. If I connect directly to the FTP server using the same login and password, all works well. If this can't work, does anyone have Zope FTP server connections being tunneled through an encryption layer? I'd really like my developers to be able to use their favorite editor with an FTP connection, but I really don't want management-capable passwords flying around in the clear.

I don't think this works for me though, because I don't want to count all of the sequence items, just the ones that match a certain criterion.

No, that's not the case. Nice thought, though. I've discovered (with Jonothan Farr's help) that the problem doesn't occur in Zope 2.1.6, only in 2.2.0. This leads me to think that a) it's a new bug in 2.2.0 I've uncovered or b) there's something different about the way Zope 2.2.0 handles the REQUEST object that I need to understand and account for. I've discovered (quite by accident) that an attempt to add a Squishdot installation (Squishdot-0-4-1) into Zope 2.2.0 generates the same error that my code generates. There's a note on the Squishdot page that indicates that they know it doesn't yet work with 2.2.0, and that it will soon be resolved (by Squishdot-0-4-4, they promise). There's no indication, though, of whether the Squishdot author(s) know what the problem is at this point. I'm considering making a post to Zope-dev describing the problem and asking if anyone knows whether this is a feature or a bug that I'm bumping into. rob (p.s. I've just had a thought that I might be able to force the loop to sort the files by type, which would at least guarantee that all of the directories would be consecutive. I could also maybe construct a new list of just the directories and then iterate over the new list. Either of these may allow me to use the "sequence-" values constructively. I want to learn what's going on here, though, and I'd rather not have to resort to complicating my algorithms. Counting stuff is a basic programming task, it should be able to be accomplished in a straightforward manner.) ___ 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 )

I'm stepping through all of the files in a LocalFS directory, and I want to dynamically create a that displays all of the sub-directories of the current directory. I want to inject a "" every so often, so I need to count the number of directories I've found so far to see whether I need to start a new row or not. I've spent a few hours digging through the list archives, so I know that creating a manually managed counter variable is not a straightforward affair. Here's the code that I have: In case we end in the middle of a row... The error I get, running Zope in debug mode, is this: Error Type: AttributeError Error Value: 'string' object has no attribute 'set' This is referring to the line in the middle of the loop, the one that actually does the incrementing. It thinks that REQUEST is a string, which of course doesn't have a "set" attribute. I've been banging my head on this all day and can't come up with an way to accomplish this trivial task. I don't want to push this into Python; this is simple UI code, not business logic, so it doesn't belong there. Besides, it's absurd to think that I would need to write an external method or some other Python method to do something as simple as this.

I've searched through the list archives and come to the conclusion that your solution above is the cleanest way to handle this, for now. There are other ways, but they involve ugly-looking permutations of the "_" namespace variable, and they approach the splendor of Perl in their readability.

[Zope] HTMLFile from within a method?
Greetings. I'm a fairly experienced Python programmer, but am new to Zope.
I'm working on a Python product, and through this process I'm learning my way
around the Zope innards. I'm running Zope 2.2.0b3 on an RH6.1 box.
By declaring a class member that is an instance of the HTMLFile class, I
can publish dtml files. This is right out of the "Boring Product" How-To; it
looks like this:
--
class Product(Implicit, Persistent, RoleManager, Folder):
index_html = HTMLFile('index', globals())
--
Then when I browse to an installed instance of my Product, I'll see the
appropriate output generated by my 'index.dtml' file, which is in the same
directory as my Product's python modules.
What I'm having trouble doing is something similar but from within one of my
Product class's methods. I've tried this:
--
class Product(Implicit, Persistent, RoleManager, Folder):
def form_handler(self, REQUEST=None):
return HTMLFile('form_results', globals())
--
This causes the output to be munged, like so:
<dtml-var standard_html_header>
<dtml-in "REQUEST.keys()">
... and so on ...
I've also tried:
--
class Product(Implicit, Persistent, RoleManager, Folder):
form_results = HTMLFile('form_results', globals())
def form_handler(self, REQUEST=None):
return self.form_results()
--
This causes zope to attempt to publish the object, but the object (my DTML
method, stored in "form_results.dtml") doesn't seem to have access to the
Product's namespace. That is, I get an error like:
Error Type: KeyError
Error Value: standard_html_header
...even though there's definitely a standard_html_header defined.
Finally, I've tried this:
--
class Product(Implicit, Persistent, RoleManager, Folder):
def form_handler(self, REQUEST=None):
dtml = open('lib/python/Products/Product/form_results.dtml', 'r')
s = dtml.read()
dtml.close()
return s
---
This causes the right data to be passed out, but it's not treated
as dtml. A garbled version of my output appears in the browser window, and if
I view source I see:
... and so on ...
I know there are other ways to accomplish what I'm trying to accomplish, but I
really want to understand what's going on here. Can anyone enlighten me as to
why I'm seeing the results I'm seeing? Does anyone have suggestions for an
appropriately Zen approach to publishing dtml files from within a Product's
methods?
Thanks for your time,
rob

Re: [Zope] Internationalization
I only have a few internationalized pages, but I'm more than half-way happy with a very simple approach: 1) an External Method "preferred_lang", which takes a list of possible languages as argument, and returns the language from that list that has the highest ranking in HTTP_ACCEPT_LANGUAGE. If there is no hit, it returns the first language in the list. import string def preferred_lang(self,langs): for lang in map(string.strip,string.split(self.HTTP_ACCEPT_LANGUAGE,',')): if lang in langs: return lang return langs[0] - This External Method is available as "PreferredLanguage" on the root folder. 2) In each internationalized page, I call the External Method with a list of the available languages (it is not the same for all pages), and then select the contents based on the result. De Hooft Familie Webdienst The Hooft Family Web etc - One advantage of this approach is that it keeps the different versions together (making updates to the information easy to keep consistent). One disadvantage of this approach is that it keeps the different versions together (making it difficult to appoint different people to maintaining the different languages), and another disadvantage is that it clutters up the dtml source.

Re: [Zope] Virtual hosts: How to make proper intra-site URL's?
Following up to my own post: RWWH> If I am looking at page:"People" should link to: RWWH> http://www.host1/ People or http://www.host1/People RWWH> http://www.host1/News ../People or http://www.host1/People RWWH> http://www.site/Host1 People or http://www.site/Host1/People RWWH> http://www.site/Host1/News ../People or http://www.site/Host1/People To accomplish this it looks like I need the "base" url not of the current page being viewed, but the "base" url (absolute location) of the dtml-method that is rendering the links. So: even if I am viewing http://www.host1/News, I want to know in the dtml method making up the the navigation bar that it is in http://www.host1/nav_bar. Is there a dtml-var that points to the current method?

[Zope] Simple tabular data. Do I need SQL?
On my web site, I have made a "News" page. The "News" items themselves are listed as a "lines"-property named "Items" on the News folder: date1;text1 date2;text2 ... They are accessed in a dtml-method: - Since this is a small listing, this is still manageable. But: I do find the ";"-delimited fields a bit hackish, so I'm looking for a better way to handle this kind of very simple tabular data. Do I really have to go all the way to a proper relational database and learn SQL? Or is there another way? If I do need to go with a real database, do I have to pay attention to the "Demo Only" warnings in GadFly? Lots of questions from a python-loving-zope-newbie.

[Zope] Virtual hosts: How to make proper intra-site URL's?
I have set up a site: www.site In this site, there are a few virtual hosts: www.host1 --> www.site/Host1 www.host2 --> www.site/Host2 Thanks to a nice access rule, both the left and right names can be used to refer to the information. So far so good. In www.site/Host1 I have define a navigation bar dtml method to show some important check points in the host. Question: How do I make relative URLs in the navigation bar work so that they work under all circumstances. E.g. if I have a "People" Folder under "Host1" listed in the navigation bar, I'd like to see that the link shows up as follows: If I am looking at page:"People" should link to: http://www.host1/ People or http://www.host1/People http://www.host1/News ../People or http://www.host1/People http://www.site/Host1 People or http://www.site/Host1/People http://www.site/Host1/News ../People or http://www.site/Host1/People I have not been able to produce this effect using either BASE0..N or URL0..N.

[Zope] Newbie alert! Frustration right off the bat...
and so it starts... I'm determined to learn zope for my next project and can't even get past the tutorial. Using zope v.2.16 on windows. I get to the part where I create the 1st DTML method (index_html) and zope reports an error: Error Type: Bad Request Error Value: the id index_html is invalid - it is already in use. This is in a virtually empty system. I suspect that the problem is in initializing the tuturial. I suspect further that the tutorial text and graphic figures don't jibe. The beginning of the tutorial says to create the ZAcme folder under my root installation. I take this to mean at the main manage entry point, rather than my literal root directory (as it says further down the page). When I do this, the ZAcme folder shows up in the workspace but the illustrations don't show this. I continue along and end up getting the above error. I also tried manually creating folders in my actual root directory (C:\) and in the zope directory (C:\Program Files\ZAcme) and I get the above error every time. Help!

Thanks for the info. I'll be reading through it. In the meantime we're using a script that checks for http connectivity.

I had similar problems some time ago (which have not been entirely resolved -- I'm still trying to tie them down -- but now seem to be less frequent), which seemed to be related to particular page accesses. Are you able to identify from your logs any pages/methods that have repeatedly been called prior to Zope going down? See the Wiki at: http://www.zope.org/Members/tseaver/Projects/HighlyAvailableZope/TwistingInT heWindProblems and take a look at DiagnosingHangProblems for some suggestions.

It was the command line within the shell. Actually, I've found something that's interesting... The system clock is an hour slow. The logs are written 6 hours ahead.

[Zope] Strange Zope behavior/Instability
For reasons unknown we lost http connectivity to our Zope server three times last night. I've checked the http logs and, as I suspected, didn't find anything unusual around the time we lost connectivity. The Python processes are still running and everything looks normal except for the connectivity problem. Does anybody have any idea what might be causing this? I haven't found anything. Here are some specifics about our setup... version of python: 1.5.2 operating system: Linux 2.2.12-20smp (Redhat 6.1) services running on machine: MySQL 2 instances of Zope Python machine specifics: CPU: 0.04 MEM: 31M of 512M Swap: 528688K free Disk Space: GB's available on all partitions Hardware: 598 Mhz Pentium III, 4 17.4 GB SCSI hard disks version of Zope: 2.1.4 Thanks, Rob ___ 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] Zope Instability
Hi, We recently setup a Zope server and it has been running great until this morning when it stopped responding, twice. There are no errors, core files or indication of a problem except that the server stopped responding to http requests. All processes were still running and a simple restart remedied the problem both times. Has anybody had any similar problems, advice, etc. We are running two Zope servers serving two different sites. Both servers run as the same user.

[Zope] Welcome Aboard!!!
Hello everybody! Please join me in welcoming Ethan Fremen to the Digital Creations team!! Ethan is in the process of relocating and should be joining us in our Virgia offices in the very near future. Welcome Ethan! >From Ethan's man page """ When I was twelve years old, I swore a mighty oath to myself that I'd get off this ball of rock before I died- and I even had some harebrained schemes to do so, probably inspired by to much R. A. Heinlein. As I got a little older, I realized that it wouldn't do to start spreading humanity about the solar system without significant changes in the way we interact with each other, the way we work together, and the way we deal with conflict. This led me to an exploration of the basic issues, like why are we here, why am I here, what am I anyway, what is the stuff that existence is of, and other abstract playthings. I've come to some conclusions, but the most important of these is that I contend that existence is communication. Of course, I had already nurtured a love affair with computers, from my original TI-99/4a (with voice synthesis!) to the Original Macintosh, that had flowered into a typographic and guerilla publishing bent. Meeting the love of my life online, I moved to Portugal to be with her. The sysadmin at the place I worked said "hey, we've got this big printer, print what you like"- and so, over two thousand pages of printed standards later, I was a web machine. Zope was a natural: it mapped to my thinking better than any other web tools I've ever encountered. After I built one site with Zope, I was determined to use it to my own ends- but there was no Zope hosting provider to meet my needs: Thus, imeme.net was born. Life has taught me that communication and community are the two most important things I can possibly be working on. As a Zopista Community Liason, I get to focus full time on helping our community grow and thrive. I was born in Washington, D.C., but moved away at 6 months of age. Working with Digital Creations brings me back full circle: A new beginning that incorporates all I've learned.
