Wrong mime type sent by Zope on every page
by dillera＠isc.upenn.edu 09 Jun '00

Hello: It was just brought to my attention that Zope (using Zserver) is sending the wrong MIME type of all its pages. Here is the header from zope: (some lines have been cut) ------------------ HTTP/1.0 200 OK Server: Zope/Zope 2.1.6 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Thu, 08 Jun 2000 15:45:23 GMT Ms-Author-Via: DAV Content-Type: application/octet-stream Last-Modified: Thu, 8 Jun 2000 15:45:07 GMT Here is one from apache: ------------------------- HTTP/1.1 400 Bad Request Date: Thu, 08 Jun 2000 15:29:59 GMT Server: Apache/1.3.6 (Unix) Content-Type: text/html I want Zope to be sending text/html, as some browsers want to download the page rather than view it. I haven't discovered anywhere to configure this. I read the Setting the MIME Type of a DTML Method http://www.zope.org/Members/anser/howto_dtml_mimetype which claims that you can set the mime type of a method by putting it at the top of the method. I did this on a test page, but still received the same header from Zope. Can someone shed some light on this? 1. how to set the mime type for all methods and documents of Zope 2. What is the Ms-Author-Via: DAV in the Zope header? WebDAV? thanks, andy diller

Getting a specific user role
by Mabe, Brad 09 Jun '00

09 Jun '00

Forgive me if this has been covered before. I am implementing a login/security scheme through the use of GUF and SQL methods. My user and role information is kept in a SQL database and a user can have more than one role assigned to him/her. What I would like to do is check if a specific role has been assigned to the current user, and then display some additional menu items if that role has been assigned. I haven't been able to figure out how to get and check the roles that have been assigned to the current user. As usual, any help will be greatly appreciated. -=Brad=-

You may try to look into the OS documentation to find, whether you can specify a default thread stack size. If Python uses Posix threads on your machine, you may find the information in the "pthread_create" documentation. If you find nothing, I fear, you will have to fetch the Python sources, provide large enough stack size and recompile. Dieter

worldpilot has issues with imap when the INBOX is open by some other application . . . . . should be able to display and allow composition of email (pine does this, for example, if I have my mail open in another imap client).

Several users having problem accessing field names of a ZSQL Method
by Jones, David H 08 Jun '00

08 Jun '00

I am a new Zope user and am attempting to access field names of a ZSQL method. I have read and tried to use the How-To : "Access the field names and fields of any arbitrary ZQSL query" by teyc. The code suggested there has not worked. For example, when I use the code: <dtml-in SQL.names> <dtml-let vname=sequence-item vvalue="SQL()[0][_['sequence-index']]"> <dtml-var vname>, <dtml-var vvalue><br> </dtml-let> </dtml-in> I get the error: Error Type: KeyError Error Value: SQL.names I have nested the above code in code that references a ZSQL method, as well as trying several other permutations, but nothing has worked. I'm wondering if this is a name lookup problem. In checking this news group I see that several others have had similar problems. See: http://zope.nipltd.com/public/lists/zope-archive.nsf/Main?SearchView=++&Sta… Can anyone tell me (us) how to correctly do this, or what mistake I (we) am making.

Problems uploading large attachments
by Cary O'Brien 08 Jun '00

08 Jun '00

I am using confera to help coordinate some development work I would like people to be able to upload large (100k) attachments into the system so the documents can be shared by people at different sites. I find that things work fine for small attachments, but for larger attachments, Zope is very slow in reading from the socket, and the browser often times out. Any ideas? Also, couldn't seem to run strace on the zope process. I started under strace but the system went bezerk opening sockets or something. Is there any way to start a single-process non-threaded zope server? (Oh, Zope 2.1.6, Linux glibc/2.0.something kernel,ix86). -- cary

search on search results, dynamically
by Philipp Dunkel 08 Jun '00

08 Jun '00

Hi out there, I have a Catalog that indexes ZClasses (only one type). Now I want to show the user all Instances in a list when they come to the page. The user should be able to use a search form to tailor down the amount of results, e.g. if my ZClass would handle Cars, they first see 500 car-objects, then they specify only reds, they get 200 results from the 500. Now they can specify a price and again the amount goes from 200 to say 50. This means I have to search on the results. Does anyone have an idea how to do this?

RE: [Zope] Wrong mime type sent by Zope on every page

I'll throw out a proposal on this. It also is not perfect, but seems to strike a happier balance. When HEAD is called on an object, what currently happens is: if a 'content_type' attribute exists, it is used else if the object's id seems to have a file extension (. in the id), try to use guess_content_type else fall back to the hated application/octet-stream (or, I've seen x-unknown-content-type used before, but I don't know if this is really any better). What if we change this to: if a 'content_type' attribute exists, it is used else if the object's id seems to have a file extension (. in the id), try to use guess_content_type > else if there is a 'default_content_type' attribute, use that else fall back to the hated application/octet-stream (or, I've seen x-unknown-content-type used before, but I don't know if this is really any better). Then we could put a 'default_content_type' attribute in the class of dtml documents and methods, which would take care of the most common case. Thoughts?
