...Just to kind of wrap this thing up... Thanks to those who helped me figure this out. As several people have now suggested and confirmed, the problem was the partition I had /var/tmp on filling up during the upload process. Moving /var/tmp to a bigger partition cured the basic problem I was having. However, transferring of extremely huge files still put more of a load on the system than I would've liked. In the end, what I've ended up doing is setting up a separate standalone FTP server, locking it down as much as possible and using an html/script front-end to allow some degree of integration with the rest of my Zope site. It's not quite as nicely integrated as using Zserver's native http/ftp capabilities, but it does the job. > -----Original Message----- > From: Jim Penny [mailto:jpenny@universal-fasteners.com] > Sent: Wednesday, January 16, 2002 7:22 PM > To: larry_prikockis(a)NatureServe.org > Subject: Re: [Zope] LocalFS and mega-uploads > > The /tmp path hypothesis does seem correct.

Unknown entries in PCGI log (Urgent Please help!)
by Steven Grimes 18 Jan '02

18 Jan '02

All, Fri Jan 18 11:48:12 2002 pcgi-wrapper: Failed to start resource (101) failure during start I've gotten the following error in the pcgi.log file. After this error I have to restart the zope process. I've tried searching the mailing list archives with no luck. Anyone have any clues? Also, is there anywhere that I can find a complete list of the pcgi errors? Current configuration: Window NT 4 SP 5 Zope 2.2.0 running through IIS 4 with PCGI.

Zope as daemon
by Allen May 18 Jan '02

18 Jan '02

I want Zope to run in the init.d as a daemon. Every time I've tried to set it up to run /zope/start it holds the process. It doesn't run in the background. I've tried copying code from the forum on Zope.org but no luck. Is there and easier way to make Zope an auto-run service.. this is import if we need to reboot the server. Thanks Allen May MCSi Web Admin 800.842.1702 x7628

Product->refresh broken in zope-2.4.3?
by Sven Rudolph 18 Jan '02

18 Jan '02

Hello all! After "refreshing" my product I can't create new instances of my product any more. I get the following error message: 'Object of type "None" is not callable' This happens even if I didn't change anything in my source code. Just clicking the "refresh" button is enough. When I restart the sever everything works fine again. This behaviour is new in zope-2.4.3 (I updated from 2.4.1) Is this a known bug? Must I downgrade again to 2.4.1? Thanks in advance Sven -- Sven Rudolph GermanMedicalServices.de GmbH Unter den Eichen 5, 65195 Wiesbaden Tel.: 06 11 / 97 46 25 2

Zope Not Being Logical
by Wade Pearce 18 Jan '02

18 Jan '02

Ok, Recently we had a site crash due to a corrupt Data.fs file. We attempted to recover the file using fsrecover.py but could never get it to run properly with Zope. We always got a Proxy Error: Connection Refused. So, we loaded a dated Data.fs file that is some 450MB smaller. Now, within zope/var, we have two Data.fs files: - Data.fs is the dated Data.fs at 245MB in size - Data.fs.Oz is the attempted recovered Data.fs at 695MB in size. But the strangest thing is happening. If we attempt to load Data.fs.Oz with Zope, it fails to work. But after attempting this, we restart Zope with the older Data.fs and the site contained within Data.fs.Oz appears. To further confuse matters, Data.fs.Oz continues to grow and when we create *.zexp files, they are coming from Data.fs.Oz. The older Data.fs file has not changed size since we discovered this back on January 10. Below is an ls -l of the zope/var directory over a period of time this morning: golum:/var/lib/zope/var# ls -l total 1738132 -rw-r--r-- 1 angel1 angel1 245093502 Jan 10 20:52 Data.fs -rw-r--r-- 1 root root 700849746 Jan 18 10:58 Data.fs.Oz golum:/var/lib/zope/var# ls -l total 1750088 -rw-r--r-- 1 angel1 angel1 245093502 Jan 10 20:52 Data.fs -rw-r--r-- 1 root root 707298826 Jan 18 11:22 Data.fs.Oz For some reason, Zope has loaded Data.fs.Oz and is using this. One thing I did notice was that when we tried to directly load Data.fs.Oz (as Data.fs), no z2-pcgi.pid file was created. Any ideas on what is causing this would be greatly appreciated. We've currently got a list of up-to-date *.zexp files from Data.fs.Oz, and during a quiter time, we're thinking of creating a clean Data.fs and uploading the data. The only problem we have is that we don't know if the clean Data.fs will inherit the problems of Data.fs.Oz because its buried within one of the folders. Cheers, Wade Pearce

apache + vhm & http-rfc compliance
by Oliver Bleutgen 18 Jan '02

18 Jan '02

I'm cc'ing one author of a vhm howto on this, couldn't find more contacts for relevant adresses. There is a small issue with the often used rewrite rules for apache + virtual host monster. All examples I have seen look like (sorry for the wrapping) RewriteRule ^/(.*) http://localhost:25080/zopefolder/VirtualHostBase/http/%{HTTP_HOST}/Virtual… [P] But, as I had to find out, this isn't completely HTTP/1.1 compliant, in so far as the client may send a host-header _with_ port number, i.e. Host: www.hostname.tld:80 which breaks above rules. When trying to leech my own site with wget, I was very astounded to get an 404 error, regardless what I entered as an URL. I use an extra condition to avoid that problem and do another rewrite if hostname has the port appended: RewriteCond %{HTTP_HOST} ^.*:80$ RewriteRule ^/(.*) http://localhost:25080/zopefolder/VirtualHostBase/http/%{HTTP_HOST}/Virtual… [P] http://localhost:25080/zopefolder/VirtualHostBase/http/%{HTTP_HOST}/Virtual… [P] Just wanted to mention that before internet explorer 7.8SP13 decides it wants to use the above rfc-option and a ton of zope-sites break seemingly for no known reason. Maybe VHM could/should be adapted? cheers, oliver

zope subtransactions with atomic commits
by Joseph Wayne Norton 18 Jan '02

18 Jan '02

Kapil - I have been doing some searching through some of the zope mail archives and the zope.org site. I ran across the following e-mail (quite old) from you ... http://zope.nipltd.com/public/lists/zope-archive.nsf/242bb7cc2b2c343d802568… I'm wondering if you have any further updates on the above subject. I have a similar requirement. I would like to be able to perform 1 or more "checkpoints" within a single zope request. If the request transaction is aborted, then only changes since the most recent "checkpoint" should be rolledback. Any ideas or suggestions? - j

Tomcat vs Zope
by fsd fds 18 Jan '02

18 Jan '02

ok ok, I know, I don't want to start a holy war here. I've been using Zope for a while, and I love python, but I see many people moving towards java/jsp/tomcat. I've studied java, but never liked too much, and so I tried to avoid it. But with all this "momentum" behind it, I think I might give it a try. Of course, being this a zope list, I know i'll get more positive opinions about the zope platform, but I'd like to hear from people who have tried both zope and tomcat: * what are the strenghts and weakness of both platforms? * is it possible to have something like the Zope Management Interface for Tomcat? * is tomcat web development object oriented as the zope one (I just love having objects that talk to each other and produce the pages. Makes design much easier and powerful) well, thanks in advance to the great zope community! Joe
