Are you saying that manage_addPhoto >completes *before* the exception? The exception you posted is pretty clear >to me -- line 8 (before manage_addPhoto), no 'the_file' key in the 'request' >var. How can the line after it be successful if this is the case? On first reading your response, I thought there was a difference between the code generating the error response and the code I posted. Just to be sure, I reran the test case and, yes, you are right. The exception identifies the line just before the manage_addPhoto call. BUT, by the time the execption is raised Photo has already successfully added the photograph. I am at a loss to explain the fault. The passed in REQUEST looks fine if I replace manage_addPhoto with a script the dumps REQUEST to the screen. The 'the_file' variable is a FileUpload object as I would expect. Whatever is going on, it's very repeatable on my system. Thanks for your help.

POSKeyError on zexp import

I am getting errors like this on import 2002-07-15T21:40:39 ERROR(200) ZODB Couldn't load state for '\x00\x00\x00\x00\x00I\x97\x93' Traceback (innermost last): File /usr/lib/zope/lib/python/ZODB/Connection.py, line 447, in setstate File /usr/lib/zope/lib/python/ZODB/FileStorage.py, line 582, in load (Object: /var/lib/zope/var/Data.fs) File /usr/lib/zope/lib/python/ZODB/FileStorage.py, line 557, in _load (Object: /var/lib/zope/var/Data.fs) POSKeyError: 0000000000499793 I have tried to look at that object directly using >>> import Zope >>> app = Zope.app() >>> ob = app._p_jar['\x00\x00\x00\x00\x00I\x97\x93'] However that object does not exist in the db since zope aborts the import. Hence you can see my problem. How can I open up a zexp file and see what is in it to find out what objects are causing the problem to figure out what is going wrong.

total "hits" in dtml-in?

Sorry is this is a second posting On 16 jul 2002, you wrote in ZopeList: > I know I could do a len() of the query, but that > seems like a bad idea because the database would essentially get queried > twice - once to get the len, and once to create the <dtml-in> list. Hope I'm not wrong, but i think this should cache 'yourquery' for the <dtml-in>. <dtml-let query_result=yourquery total="_.len(query_result)"> <dtml-in expr="query_result" size=x> </dtml-in> </dtml-let> On the other hand, i'd be interested to know how you get results x and y in 'x to y of total' cheers, Dirk

ISSUE with ZEO + Squid please help!!
by Gustavo M. Palomares Reyes 16 Jul '02

16 Jul '02

Hi, I have a problem with squid and ZEO. I was using in one machine a squid and Zope, but the site was comming slow, so i decide to move to a three computers architecture and a load balancer. I have one data storage and two Zeo Clients. In both zeo clients I put squid, both of them pointing to local machine in accelerated mode (non-real IP). Both machines non-real ip addreses and an real IP pointing to them via NAT. My load balancer point to both zeo clients through the internal IP. I saw with a day with no load the site works good , but in days with much load the site start to work strange, it begans to slow his replies dramatically. I saw my zeo clients and apparently everything works fine, I saw also the CPUS load, and zope do not use much cpu (56%) and squids neither. Im desperate, i dont know what to do im new in squid connecting to ZEO, i saw the how-tos that are in Zope.org buth the one who use squid with zope is wit a configuration wit virtual host and DTML, im not using virtual host and im using ZPT's I configured my squid in the following way: acl all src 0.0.0.0/0.0.0.0 http_access allow all http_port 80 httpd_accel_port 8080 httpd_accel_host localhost httpd_accel_single_host on httpd_accel_with_proxy on memory_pools off ie_refresh off the rest its the default stuff. Also i put siteRoot in my zope pointing to my load balancer (eg.base http://mydomain.com) to force zope to pass first through squid. Because if i took off this my squids, sent back a reply to my users like this http://localhost:8080/myzpt.html Im using Zope 2.5.1, squid 2.4 and Zeo 1.0 My Zeo clients has 730 Mb RAM Hope somebody can help me tavo

I tried the suggested change with no effect. (Inspection of the REQUEST structure had already established that it was reasonable and without name conflicts.) Perhaps it was not clear from my posting: the upload process completes successfully prior to the point where the exception is thrown. Moreover, I have checked the type of the form variable, 'the_file' and it is correct as is its contents. As the problem is still with me, any further suggestions would be appreciated.

Heeeeeeeeeeeeelp (login problem)
by Breuer, Yvon 16 Jul '02

Hi Zope-wizards, As you can see in my subject: I'm getting quite frustrated by some stupid error when I'm trying to login to my Zope server. (Yep, I'm a newbie...) SITUATION I'm going to create a website to gather funds for a hospital in Ghana (St. John of God Hospital in Duayaw Nkwanta). To get an idea about the situation: http://www.zwo.nhl.nl/hbov/buitenlandstage/ghana.html (Dutch & English). WEBSITE I want to do this with Zope & Python. I want people to be able to do online donations, retrieve information about the project, maybe send a mailinglist to keep them up to date and there are many more plans. So: I've got a lot to learn... LEARN & DEVELOP @ WORK & @ HOME In order to learn as quickly as possible I tried to install Zope at work and at home (of course during my break ;-) ). At work (Win2000 Prof.), everything functions OK. I've done the tutorial and I'm now working myself through the ZopeBook. So far so good, but... MY PROBLEM At home I've installed Zope (2.5.1) on my computer (Win98). No errors occured during installation. So, just like at work I tried to login to Zope for the first time, but... When I start the START.BAT, my computer starts a dial-in to my internetprovider! It seems this occurs when START.BAT is trying to retrieve my hostname. When START.BAT is finished, I've tried to type in... * http://127.0.0.1:8080/manage (START.BAT comes up with 127.0.0.1 as localhost and 8080 as port) * http://popeye:8080/manage or http://popeye:8021/manage (popeye is the computername in my Win98 network-settings and START.BAT comes up with popeye as localhost for port 8021) * http://localhost:8080/manage (should always work, right? Not!) * http://stjohnhospital:8080/manage (stjohnhospital is the superuser I installed Zope with) ... but none of them works!!! All that happens is that my browser (MsIE) when I'm OFFLINE shows me that the page cannot be found and when I'm ONLINE it shows me either "server error" or "page not found". >:-(( NB: It doesn't matter wether I login to my internprovider or not. I'm quite sure it's nonesense to be online in order to login to a local Zope-server, but hey, I've tried everything possible (as far as I know). I also tried to un- and reinstall Zope, but that didn't work either. :-( So please, help me out here!!! (In a short while I've got some days off and I want to do some work for the website at home.) Not only me, but also the people we're trying to help will be very gratefull! ;-)) Best regards, Yvon Breuer

Hi *, How can I change the port Zope runs on when Zope is running as a WinNT Service? After adding the -w80 switch to start.bat and restarting the Zope Service, Zope is still publishing on port 8080? Am I missing something here? Regards, Michael

RE: [Zope] ZSQL Method problem

Hi, Sorry, I solved the problem, the db had empty fields (nulls) and it does like that. Once I put in something I could see it. Thanks. -----Original Message----- From: zope-admin(a)zope.org [mailto:zope-admin@zope.org]On Behalf Of McDonnell, Larry Sent: Tuesday, July 16, 2002 10:28 AM To: 'Zope@Zope. Org' (E-mail) Subject: [Zope] ZSQL Method problem Hi, I have come across a strange problem in ZSQL Method. I am using OBDC adapter to MS Access. Below is real information. part_num:string="%" title_description:string="%" category_type:string="%" select * from part_number where (part_num like <dtml-sqlvar part_num type="string">) and (title_description like <dtml-sqlvar title_description type="string">) and (category_type like <dtml-sqlvar category_type type="string">); To test this query, I input the following: Part_num 66% title_description % category_type % My results: There was no data matching this Type Part Number Search query. select * from part_number where (part_num like '66%') and (title_description like '%') and (category_type like '%'); If I remove the variable category_type I will see records displayed with a part_num starting with "66". If I add it back I get no results. All the variables has information stored in the db. I have used other ZSQL methods with as many 4 parameters and they work. I thought maybe there were some reserved words and changed it to document_type but the same results. Any clues? Larry McDonnell Proton Energy Systems 50 Inwood Rd.

Zope+Apache - probably trivial problem + one tip :)
by Pawel Lewicki 16 Jul '02

16 Jul '02

Hi, I've installed Zope and Apache following the instruction I found. Rewrite line looks like this: RewriteRule ^/(.*) http://localhost:8080/VirtualHostBase/http/localhost:80/VirtualHostRoot/$1 Everything works just fine, except for one little thing. How to get rid of browser address looking like : http://localhost:8080/VirtualHostBase/http/localhost:80/VirtualHostRoot/ And request for a tip: How to make it working with SSL tunnelling? (already configured - https://localhost works fine and all attempts to change the rule above fail ) Pawel Lewicki
