I need to make sure Since you say: a) you are new to Zope b) you don't want to use sessions c) you need to do something that is exactly what sessions are for, I'll have to ask - what are the conditions and the course of action that makes sessions cause problems? And whatkind of problems they are - and is the reason for these problems sessions or something else? And as a reminder: 1) HTTP is a sessionless protocol - there is no such thing as a session in the protocoll 2) Passing variables or arguments happens usually either in the URL ( http://xx.xx.xx?foo=bar&dinner=spam ),as a form field or in a cookie. 3) Since passing multiple arguments all the time is stupid - systems for storing the data with a session key have been developed to practicly all the web development platform. Instead of passing all the arguments you just pass the session key. And then the session key gives you access to all your arguments. And when you are done, you can just remove the arguments or kill the session. Now. Is the session mechanism really the problem? -huima

Zope won't start
by Scott 09 Sep '02

09 Sep '02

I have installed zope on Mandrake 8.2 from rpms. The docs say to start zope with "etc/rc.d/init.d/zope start" and when I do this from the command line it says OK. But zope does not really start. I can't connect to zope from my browser and if I do "etc/rc.d/init.d/zope stop" it fails because it was never runnung in the first place. Does anyone know what the problem might be? Thanks, SW

FTP defaults, overloading, or monkeypatching?
by Terry Hancock 09 Sep '02

09 Sep '02

Hi All, I've implemented a replacement image object that I would really like to be the default on my site. I've thought of a few different approaches, and would like to see if there's any wisdom out there on which might be the easiest (or perhaps safest?) approach: 1 FTP defaults Can I change what product class is used to load image data when it is "put" from the FTP interface? I'm not sure how it decides this, but when I upload images they always appear as plain Zope images. This would probably be the most convenient solution, even though it won't do much about the ZMI upload (but I can use permissions to make the custom image easier to find), and, of course, it won't fix existing image instances (but that's a temporary problem). 2 Overloading Could I overload the product class with my product? E.g., could I just change "meta_type" to image in my product and have it clobber the plain Zope image? Sounds scary, but maybe possible. 3 Monkeypatching This would probably be the least convenient approach -- start with Image and overload all its methods. However, this is the only method I've actually seen in use. Opinions? Thanks!

xmlrpc and fastcgi on IIS
by Marco Catunda 09 Sep '02

09 Sep '02

Hi, I have tried to use xmlrpc on fastcgi zope support at IIS. I think IIS doesn't pass correct headers to zope, so Zope understand the xmlrpc request as html request. I decided to use xmlrpc request at 8080 port of zope, and html request through IIS. But I was using IIS authentication. So I can't authenticate xmlrpc request. Is there other idea to resolve it? -- Marco Catunda

LFS (large file support)
by Roel Van den Bergh 09 Sep '02

09 Sep '02

We're running out of luck We need LFS (large file support) for the Data.fs file Upgraded to RH 7.3, ext3 filesystem, compiled our own python 2.1.3 and build zope 2.5.1 from source Exported all sites from previous zope and imported in new zope to avoid conflict with existing Data.fs but no luck Everytime we want to go over the 2GB limit zope truncates the Data.fs Did we mis some configuration settings? TIA, R. - - - Roel Van den Bergh

Zope cookies data point
by Kyler Laird 09 Sep '02

09 Sep '02

I know it seems like I'm the only one in the world who doesn't accept cookies, but recently my boss was having problems cutting and pasting in Zope. He'd done it before, but it had stopped working. It turned out that cookies had been disabled on both of his browsers (not sure how). I tried to explain that Zope used cookies instead of saving selections on the server. It was embarrassing. Anyway...I'm willing to pay a small bounty for someone to get rid of cookie dependency in the management interface. --kyler

Kaivo Document Library customisation?
by Richard Hewison 09 Sep '02

09 Sep '02

I've been able to customise a fair amount of the standard Kaivo Document Library product to meet our own needs, but have now hit the limit of my current knowledge and understanding. The author of the product (Casey Duncan) has kindly dropped a few suggestions to me in the past, but I still don't understand how to achieve what he has suggested. What I'm trying to do is automate an email to be sent to the author of a submitted document 6 months afterwards to say "Please re-visit your document". I added 'email' to the DL document properties and the 'document_submit' form, and the 'created_date' is already defined in the DL product. I created a simple 'sendmail' dtml document (using a Mail host object) which automatically sends an email to the librarian (me at the moment!) from the author's email address. This tells me whenever a document has been submitted to the library, so I can go and approve or decline it. Casey's suggestion was to create a dtml method within the Document Library that queries the library for old documents and then sends the author an email. You then use the OS command line utility 'wget' in a script to execute the dtml method periodically via a cron job on the server. We could get the email sent from outside of Zope, but it is probably neater for everything to be done inside and just use 'wget' to run the method automatically. The bare minimum info we need from the document library Document Store object (which is called 'Documents') is 'email', 'review_date', 'filename' and 'title' for each and every document file (word, excel or pdf file) inside it. Trouble is, I don't understand enough about how the DL product works. I know that the 'Documents' Document store object isn't a normal folder but I have no idea where to start on examining it and getting the info out! Richard Hewison
