Problems with SybaseDA
by A J Wilson 08 Jun '00

08 Jun '00

Hi I have installed Zope-2.1.6 on my PC (Pentium running Mandrake 7) and it seems to work fine. However, I have tried installing the SybaseDA and am having trouble. I have downloaded and installed the common Sybase libraries, set the SYBASE path, complied it without errors and moved the sy_occ.so up one directory. However, when I restart Zope it fails and produces a core dump. There are no errors generated so I am having trouble diagnosing what is wrong. I can import the sy_occ.so into python without error, but if I try to import db.py and DA.py I get errors. These two scripts reference modules such as DateTime, zLOG, Missing, Globals, Shared.DC.ZRDB.TM, and Shared.DC.ZRDB.Connection - none of I can find. Can anybody please help? Thanks Austin

Zope Weekly News for June 7th
by ethan mindlace fremen 08 Jun '00

08 Jun '00

This week's somewhat abbreviated ZWN includes Zope at LinuxTag and the Open Source Convention, lots of documentation progress, including a chat, a new home for Zope Studio and more! The opinions expressed in Zope Weekly news are solely the author's, and not the opinions of Digital Creations, The Zope Community at-large, or the Spanish Inquisition. The Zope Weekly News now has a "permanent home", http://www.zope.org/Documentation/ZWN. And Now For Something Completely Different: Coming Events LinuxTag There will be a Zope booth at the "LinuxTag", http://www.linuxtag.de in Stuttgart, Germany from June 29th to July 2nd. In addition to the booth that will be there for the whole conference, there will be 2 rooms available for talks and discussions on the business day, Thursday 29th. We are still looking for people who want help organizing the conference, give some talks and attend the booth. Generally, it would also be great to know who is planning to be at the conference. Please send feedback to "Stephan Richter", mailto:srichter@plandepot.com See "Zope at Linuxtag", http://www.zope.org/Members/Linuxtag/ for the most up-to-date information. The Open Source Convention This "enormous convention", http://conferences.oreilly.com/oscon2000/ hosted by O'reilly, is shaping up to be pretty interesting. Aside from the State of Python, given by Guido von Rossum, there's also going to be a "talk on the CERT Advisory", http://www.oreillynet.com/pub/w/evening_events.html about cross-site scripting, a web-wide security issue that the Zope Community was among the first to begin implementing security policies for: they'll land with zope 2.2. Zope is going to be at the conference in force, with: - Paul "opening eyes to the Zope-Mozilla initiative", http://www.oreillynet.com/pub/e_sess/853 - Ryan telling the world "you can have web IMAP and collaboration", http://www.oreillynet.com/pub/e_sess/725 - Christopher, as always, concentrating on the "edification of the community", http://www.oreillynet.com/pub/w/python_tutorials.html Documentation -- by Amos Lattier This Week * Stephan Richter finished reviewing, fixing, and expanding online help content for the Zope management screens. We hope to get him set up with CVS and get this checked in later this week or next week. In addition to brining the help content up to date, he is converting it to use Structured-Text. This will make editing help pages much easier and will eliminate the two step process of editing XML, rendering to HTML and then checking the HTML into CVS. This should make life much easier for the Zope team when they are documenting their work. * Amos released updated "Zope training material", http://www.zope.org/Members/Amos/TrainingSlidesAnnounce that he and Michel Pelletier have been working on for the past couple weeks. There are twenty slide presentations which cover such topics as DTML, application design, and developing Python products. Note: the PowerPoint slides are built by a Python script that reads Structured Text and talks to PowerPoint over COM - cool. * Michel and Amos participated in an IRC chat about documentation. A transcript of the chat "is availiable", http://www.zope.org/Documentation/Chats Thanks to everyone who participated and posed great questions. We even got a volunteer commitment out of the chat - way to go ZDP folks! * Amos is putting together a wiki that details all official Zope documentation projects, their schedules and status. Look for an announcement before the end of the week. We hope that this along with weekly ZWN summaries will give folks a much better idea of what were doing on the documentation front. * Michel is working on turning his in progress O'Reilly book on Zope into a piece of official Zope documentation. If all goes well the book will replace the current Guides. We are really excited about this and think that if we are successful that this will do a tremendous amount for Zope documentation. Next Week * We plan to complete and make public the Wiki that describes all official Zope documentation projects, their schedules and status. * We plan to focus on getting docs in shape for Zope 2.2 Specifically this means shoring up the help system docs, API docs, and tutorial. This all won't get done next week, but hopefully we can make some good progress and stay on track to have everything up to date for the 2.2 final release. If we are really fast we may even sneak a DTML reference into the Zope 2.2 final release. * Hopefully we will have final word on the status of converting Michel's Book into official documentation. That means we can start the process of making the Book public and opening it up to community critique and contributions. Zope Status -- by Brian Lloyd Summary o More collector issues resolved, made progress on the todo list for the 2.2 beta. Last week highlights A somewhat shorter list this week since we have changed the scheduling of the ZWN :) 12 more collector issues were closed and the changes to the ownership model were checked in (move and rename operations no longer affect ownership, a knob was added to the import screen to allow retaining existing ownership on import). The online help for ownership and import were updated and expanded as well. This week's friends of the core: o Jeff Rush contributed several patches from his RPM distribution. o Chris Withers gets the bug-writer-o-the-week award :^) o Sam Rushing clarified the license for the medusa files underlying ZServer. Next week Finish the outstanding issues for 2.2 beta 1: o Some basic hooks to support virtual hosting (a la SiteAccess) have been designed and will be added to allow product authors to write virtual hosting support without fragile dependencies on parts of the Zope core. o Finish changes to the undo machinery that will expose a more appropriate subset of undo-able transactions to the user. The set exposed now was fine at one time, but as the line between "site management" and "site user" continues to blur, a more restricted subset will make undo easier to delegate to a broader range of users. (I think that this is actually in testing now). o Get the minimal Observable default implemention checked in to the Zope core. Note that for 2.2 at least, the only impact of this will be that ZClasses will be able to subclass the default Observable implementation. While we suspect that many builtin Zope objects could benefit from being Observable in the longer run, we want to let the interface and default implementation shake out in application usage before taking that step. o Some misc. catalog bugs need to be closed. In other news, there is now a "zope-dev wiki", http://www.zope.org/Wikis/zope-dev/FrontPage where we will begin capturing discussions on future Zope development. Zope Studio -- by Martjin Pieters - Zope Studio has "a new home", http://www.zope.org/Products/ZopeStudio/. - With the new home comes a new and improved front door, with better access to the resources. This also includes a Tracker! - I fixed the Zope Studio install issues. This should be in CVS by the time you read this. Looking ahead - More fixes to unbreak Zope Studio against the current Mozilla codebase. - Start implementation of a object handling component architecture, where new object types can be supported with installing new Zope Studio components. Zope Web -- by Ethan Fremen - The Spotlight has been altered in a mostly behind-the-scenes fashion, but they should be easier to maintain. - The second Zope Chat went over well. I want to do them every week: Tell me what the topics "should be", http://www.zope.org/Documentation/Chats/ChatTopics If you want to speak, "tell me", mailto:mindlace@digicool.com - The came_from bug "was squished", http://www.zope.org/Tracker/37 - ZopeNews properly "formats structured text", http://www.zope.org/Tracker/39

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I seem to get more than a few errors emailed to me, and am trying to track down how they are occurring. I never see these errors myself which makes it frustrating. I know the url where these occur. Most of them occur at forms. How can I get the full url including the parameters of the queries that cause the problems? ( Interestingly most of the errors occur with DNS of the client browser based in the US whereas my target audience is home in New Zealand. ) - -- Regards, Graham Chiu gchiu<at>compkarori.co.nz http://www.compkarori.co.nz/index.php Powered by Interbase and Zope -----BEGIN PGP SIGNATURE----- Version: PGPsdk version 1.7.1 iQA/AwUBOT6Ba7TRdIWzaLpMEQK/UwCgwBccUuTQt53UH1UBgU5Qfpw6lfwAn1rI IbypvR/Er3amtKjZkX9ze33g =zHAB -----END PGP SIGNATURE-----

<dtml-sendmail> and Content-transfer-encoding
by Chien-Pin Wang 08 Jun '00

08 Jun '00

Dear All: I'm using <dtml-sendmail> to send messages of Chinese characters from Zope. From time to time I got wierd mail delivery behaviors. I was told then that mail header/message body must follow RFC-822 and RFC-2047 standard with proper encoding, if not in US-ASCII. Basically these RFCs are talking about methods of encoding for non-US-ASCII characters. My question is: How do I do this in Zope? Big thanks in advance! Chien-pin

seeking help on roles, authorization, permission
by Craig Allen 08 Jun '00

08 Jun '00

I've largely been able to ignore most of the Zope security mechanisms until now, but I have this new intranet app that's causing me problems. I have a folder called Reuters that has my application's methods; it has a subfolder called Staging that has documents being reviewed and subsequently published. I need to be able to limit the publishing to specific individuals. I created users in the Users Folder in my Reuters directory. I also created an editor role in my Reuters folder, and gave it what I thought were appropriate permissions, including manage_properties. I assigned the editor role to each of my new users. Users work in the Staging folder. When my users try to publish - which invokes a method that changes properties on documents in the Staging folder and also properties of the Reuters folder, they are prompted to log in by their browser. However, their usernames and passwords do not seem to work, and after 3 tries, they get a Zope error page saying they do not have permission to manage_changeProperties. I don't get it. Any clues?

TIA. No, I won't smack you. Newbies and Oldies alike go through this problem again and again. It's part of the Zope Voodoo ritual that everyone has to dance. :) In short, use <dtml-var "modules.leftbuttons(_.None, _)"> and see the magic before your eyes. Now, a longer explanation. When you use "module.leftbuttons", Zope does NOT call the leftbuttons method, intead, it tries to get its representation string (I think.) You will soon get used to the weirdness of DTML, and you will know that the following three approaches (1) <dtml-var "modules.leftbuttons"> (2) <dtml-var "modules.leftbuttons(_.None, _)"> (3) <dtml-with modules> <dtml-var leftbuttons> </dtml-with> all have subtle differences that haunt Newbies and Oldies alike. If you can tell the difference, congratulations, you've graduated from the Zope Elementary School and understood how the namespace voodoo works. Otherwise, keep consulting the manuals or the newsgroup. :) Hung Jung ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com

Try: http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.7.3.html For accessing variables containing hyphen inside expressions, use something like: <dtml-in firetruck> <dtml-if "_.['count-firetruckname'] > 26"> ... </dtml-if> </dtml-in> (The above assumes that "firetruckname" is an attribute of an item inside the "firetruck" list.)

Help on synchronous methods?
by Craig Allen 07 Jun '00

07 Jun '00

How can I synchronize external method completion with DTML method invocation? [and do I need to?] I found an unexpected bug in a Zope content management app I am developing: the actual publishing process invokes an External Method that uses urllib and ftplib to pull rendered documents from Zope and PUT them to a web server via FTP. One of the documents is a table of contents of the "current" documents, which is generated dynamically by a DTML method that looks at a property of each document in the folder. The last step in the publishing process is "archiving", a DTML method that clears the "current" property in all documents. What appeared to be happening was that the external method was still chugging along when it came time to grab the table of contents; meanwhile, the archive method had already cleared the "current" property, so there were no documents listed in the table of contents. First question: is my hypothesis likely? Are methods - in particular an external method - executed strictly sequentially (which is what I would have assumed) or is it possible that the DTML archive method could have completed before the prior external method did? Second question: if methods are _not_ executed synchronously, is there any way I can force them to be?

Newbie question: graphics in subdirs
by Randy Edwards 07 Jun '00

07 Jun '00

I'm going to rewrite my web site in dtml and am using the latest stable Zope. Well, I should say I'll rewrite it after I get over this infuriating newbie problem I have. :-) ` I'm trying to get Zope to display an image from a subdir. I've whipped up a simple dtml document called "test". Test contains this: <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p>This is the <dtml-var id> Document.</p> <p>Now show a graphic: <br> <dtml-var logo.jpg> </p> <dtml-var standard_html_footer> That references an image file in the root directory called logo.jpg. Everything works, it displays fine. However, I want to keep all of my commonly used image files in a subdirectory called /images. So I create a folder called "images", upload another copy of logo.jpg into it, everything's fine. I change the dtml in the "test" document to be "<dtml-var /images/logo.jpg>". And it doesn't work, giving me an error message of: Error Type: KeyError Error Value: /images/logo.jpg Looking through the docs and tutorials I can't find anything on this -- and I know it's mindlessly simple. Can someone whack me with a clue-bat?

Re: [Zope] How do you changing web port address of Zserver installed as a service on Win NT4?rvice on Win NT4?

Restart your service and your set. Alternatively you might tweak the registry at key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\<yourZopename> \Parameters\start with the -p switch. But the first is easier i'd think ;-) Also see: http://zdp.zope.org/projects/zbook/book/VII/PlatformInstallation/InstallDraf ts/instwindraft3/
