[Zope] Header information on file upload
by Martin Gebert 01 Feb '03

01 Feb '03

Hi! I already asked this question on the main Zope list, but there was no answer so far; so I hope I find the right audience here... In my HowTo about dealing with BLOBs <http://www.zope.org/Members/murphy/MySQL-BLOBs> I use a rather unelegant but working method to get the content type of an uploaded file. Stefan Tjarks has now drawn my attention to the Header attributes of the uploaded form data, namely the "Content-Type" attribute which seems to reveal the MIME type (photo.headers['Content-Type'] for the given exsample). My sorrow is now that this information isn't 100 % reliable, 'cause the Zope core (esp. the Image and File classes) doesn't seem to use this possibility either, but implements it's own methods which I use in the HowTo, too. The responsible class ZPublisher.HTTPRequest.FileUpload seems only to reach through the header information from the browser. Also I've learned through SelfHTML that the MIME type support of browsers has holes sometimes, as described for the accept attribute of the <form> tag. Does anybody have further information on that issue, and why headers['Content-Type'] isn't used by Zope (it is, in fact, but in ZPublisher for seemingly other purposes)? Martin

Permission denied for users in Manger role
by Robert Van Overmeiren 31 Jan '03

31 Jan '03

Hello, Scenario: I have a web app with a form in a folder and I removed "Aquire permission settings" from the "View" permission and added the perm to the "Manager" role. The folder with the form also has an "acl_users" folder and contains users defined as "Managers". When I browse to the form in Inet Explorer, I'm prompted to log in. Issue: When I log in as one of the defined "Managers", I get three strikes then I'm out (permission denied). Why don't the logins work? More Info: I can set the "View" perm to "Anonymous" and access the form without being prompted to log in. I, as "Owner", can log in when the "Owner" perm is enabled and can't when its disabled. So, the security framework partially works, but seems to be missing something. I've tried granting "View" permission to users in the "Manager" role on a simple HTML page I imported into Zope and can't get access to that as a "Manager" either. Have other developers had this problem? Thx, Bob Van

Adding Properties to Folder Objects via a Zope Python Script
by Asad Habib 31 Jan '03

31 Jan '03

Hi. I was wondering whether any of you know if it is possible to create properties for Folder objects using a Zope Python script that can then be invoked from a DTML method. I know that this is possible using Zope's management interface, but this procedure is not scalable. Any input would be appreciated. Thanks. -Asad __________________________________________________ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable. Sign up now. http://mailplus.yahoo.com

consistently getting conflicterrors on 'intSet'
by Ivo van der Wijk 30 Jan '03

30 Jan '03

Hi All After upgrading to Zope 2.6.0 (from 2.3.3 - 2.4.4), I found the following error in my stupid.log 2003-01-30T18:53:44 ERROR(200) Zope Couldn't install OFSP Traceback (innermost last): Module OFS.Application, line 700, in install_product - __traceback_info__: OFSP Module ZODB.Transaction, line 222, in commit Module ZODB.Transaction, line 195, in commit Module ZODB.Transaction, line 256, in _commit_objects Module ZODB.Connection, line 389, in commit - __traceback_info__: (('intSet', 'intSet'), '\x00\x00\x00\x00\x00\x00\x05x', '') Module ZODB.FileStorage, line 705, in store ConflictError: database conflict error (oid 0000000000000578, serial was 034a18174c3503ee, now 0000000000000000) ------ 2003-01-30T18:53:44 PROBLEM(100) Zope No such file or directory: /var/Zope/instances/cc26/Products/PlugIns/help ------ 2003-01-30T18:53:44 ERROR(200) Zope Couldn't install ZCatalog Traceback (innermost last): Module OFS.Application, line 700, in install_product - __traceback_info__: ZCatalog Module ZODB.Transaction, line 222, in commit Module ZODB.Transaction, line 195, in commit Module ZODB.Transaction, line 256, in _commit_objects Module ZODB.Connection, line 389, in commit - __traceback_info__: (('intSet', 'intSet'), '\x00\x00\x00\x00\x00\x00\x07\x8b', '') Module ZODB.FileStorage, line 705, in store ConflictError: database conflict error (oid 000000000000078b, serial was 034a1817514f2bb3, now 0000000000000000) I've seen several reports like this, but as everything "seemed" to work, noone seems to have bothered fixing it or finding out what's happening. However, we're currently upgrading squishdot as well, and now we get the same exception each time when adding a new post (probably due to ZCatalog updates) - the posts aren't added, of course Module ZODB.Transaction, line 256, in _commit_objects Module ZODB.Connection, line 389, in commit __traceback_info__: (('intSet', 'intSet'), '\x00\x00\x00\x00\x00\x16\xf2\xd1', '') Module ZODB.FileStorage, line 705, in store ConflictError: database conflict error (oid 000000000016f2d1, serial was 034976c696679466, now 0000000000000000) So, what's going on here?

Hi all - We're planning to cut 2.6.1 b2 this Friday. I wanted to give the heads-up in case anyone was in the middle of anything that needs to get in (I saw Toby had committed some things, and it looks like that merge is complete).

New Products can't included anymore in Zope !!!!!
by David Mauser 29 Jan '03

29 Jan '03

Hi Folks, i work now for some month as a devoloper on a Zope System. I have a local workstation where i do my work and then i copy the ready product to our Server. The product has worked very fine on my machine with the same zope version as on the server (2.5.1) After i finished the product i copied it to the Server, but it doesn't work. I checked up if there is anything missing, nope. I look if there is an error while compiling the product, nope. I build an bug into the product, and see, the error gets outputed on the console. Also the files get compiled, but they don't come into the products of Zope. I tried to copy another of our products and renamed the product folder. Normaly the product gets into Zope now a second time, but nope. Nothing happens, no new products can be included. The "Last modified" in productmanagement is for the newest (2002-08-21) and this is long time ago, we changed this product 2 weeks ago and the changes have worked. Has anyone a clue what to do? Many thanks David Mauser -- Neu auf AustroNaut: Visitenkarten, Horoskope, personalisierte Kinderbücher http://www.austronaut.at/
