Help with VHM and Apache
by Russ Rollins 13 Nov '03

13 Nov '03

I've been trying to get Zope setup with Apache. I continually read that I need to add a VirtualHostMonster in order to accomplish my objective. However, I cannot find where to download this object, and the how-to seem to indicate that this file is included with Zope. Could anyone shed some light on this? Much thanks, -Russ- ********************************* Get your free E-Mail and Homepage Go to http://www.networld.com *********************************

Ape 0.7 - prob. installing
by Larry J. C. Prikockis 13 Nov '03

13 Nov '03

I'm no doubt missing something silly, but Ape 0.6 worked and now 0.7 is giving me troubles. Here's the specifics: Zope 2.6.2b4 on RH Linux 9. I have Ape 0.7 and DBTab 1.2 installed. and actually, Zope starts up fine if I remove the DBTab.conf and custom_zodb.py files from my instance root. WITH those files configured according to the instructions (pretty much the defaults) though, I get the following traceback when starting Zope: 2003-08-13T15:22:49 PANIC(300) z2 Startup exception Traceback (innermost last): File /usr/local/zope/Zope/z2.py, line 585, in ?

[Fwd: [Zope] Sessions between domains]

I am wondering how others have solved this problem. Are people using cookies between the 2 sites (I would like to avoid this) or are people writing this info to a database? Any help would be much appreciated.

newbie: ZTP, SQL, plone
by andrew cooke 11 Nov '03

11 Nov '03

hi, maybe i'm being trying too much too soon, but i'd appreciate help with the following (i'm new to zope but have used python for years and have some experience with jsp and similar web tech). i am using plone with postgresql. the DA is working. my problems are, i think related to ZTP and how to structure applications. i have the folder "timesheets" defined inside my root folder. as two subfolders i have "sql" and "ztp" in /timesheets/sql are two SQL methods: add_person and list_people. the SQL method /timesheets/sql/list_people returns a list of people from a table. this works (the "test" button produces results; the column name is "person"). but how do i get that data displayed in the ZTP page? i have a page in the /timesheets/ztp folder (also called "list_people") with the following text, but it won't compile: <ul tal:repeat="item /timesheets/sql/list_people"> <li tal:content="item/person">name</li> </ul> the error message is: Compilation failed TAL.TALDefs.TALError: Invalid variable name "" in expression '/timesheets/sql/list_people' my problem seems to be accessing the sql method that is "../sql/list_people" relative to the location of the ztp page. how i do this? or is the problem elsewhere? apologies if i've done soemthing very stupid! cheers, andrew -- http://www.acooke.org/andrew

Re: [Zope] ZODB size limitations?
by BZ 09 Nov '03

09 Nov '03

(not bragging) my ZODB currently is at around 90,000 objects and grows from 270MB -> 500 MB. It used to house almost double that and grew to 1.5GB with no problems. Obviously I did some house cleaning. There are file size limitations in some OS's (I think Linux is 2GB). 150,000 objects is no biggy and if it grew to 500,000, you would still be fine.

Tracking upload of files to Zope
by Gitte Wange 08 Nov '03

08 Nov '03

Hello, Sorry if I post to a wrong list - if that is the case, please tell me where to post instead. I have one huge problem with Zope: It's impossible to track how far an upload of a file to Zope is :-(( It seems like Zope "blocks" untill a file is uploaded to Zope making it impossible to tell how many bytes has been transfered or similar. Is it me that hasn't got a clue on how the HTTP protocol works or is it a "bad implementation" of file uploads in Zope ? I kinda hoped I could create some sort of "wait page" when users upload files to my website ... it's big files (video files) so it takes some time and therefor it would be really great to be able to display a wait page to people. -- Gitte Wange Technical Manager Email: gitte(a)mmmanager.org Web: http://www.mmmanager.org Tlf: +45 36 46 20 02 (On the statement print "42 monkeys"+"1 snake") BTW, both perl and Python get this wrong. Perl gives 43 and Python gives "42 monkeys1 snake", when the answer is clearly "41 monkeys and 1 fat snake". -- Jim Fulton, 10 Aug 1999

VarImage, Problems with uploaded files.
by Edward Pollard 08 Nov '03

08 Nov '03

Good afternoon all, I would like to use the VarImage product as part of a "notice board" project. Different ways data is access demand different sizes for the graphics, and the VarImage product seems to be the right tool for the task...almost. These will be graphics uploaded by the end user via a form, and I've encountered two problems where it seems VarImage ate my Zope server, presumably due to "bad input". 1) A huge JPG (~10MB) was uploaded. The server then died. 2) A bitmap was uploaded instead of a jpg/gif. The server then died. Both scenarios are repeatable, but by no means are my diagnosis skills sophisticated to comment any further on what's going on. So as a preamble to my actual question I'd welcome advice on how to more properly figure out whats going on here. It seems that processing threads are getting sent off into the wild blue yonder and never ever coming back. I figure the only way I can use VarImage for my needs is if I make sure that files are <500k and if they are actually gifs of jpegs. So my *actual* question is: How can I tell if an uploaded file is a gif or a jpg? I know I'll probably need to look at the first 4 bytes for some kind of code, but I don't know what that is (nor exactly how to do it) and am dead certain that someone out there has done this already.
