Zope refusing to serve our large files (180M+)
by Chris Wilton 08 Dec '05

08 Dec '05

Hi all, Sure someone's probably come across something similar, but I couldn't find anything in the archives: our zope is refusing to allow download of files greater than around 170M through the http server. We have a number of db dumpfiles we want people to be able to access. We are running Zope 2.7.0 with an Apache front (reverse-proxy, as our zope is on a non-standard port) on a linux2.4 kernel (mosix) with bags of memory; the apache end is fine - the zope installation is local and I am using the port number with all the same problems. 1) I can download a 170M file but not a 180M file through the http server. With the larger file request we get a 500 error in the trace log. The download box pops up but nothing is actually downloaded. 2) I can reach both through the ftp server but transfer rate is ridiculous (1.7Kb/sec) for a University lan. 3) Even if I could find out why ftp transfer is so slow and sort it, I seem unable to grant a non-manager read access to a LocalFS object: the properties don't stick when I change them, and Zope creates the link to the local directory with user Zope, group Zope, permissions 660, hence although managers can reach the files, nothing is reachable for an 'anonymous' user (I created a special user for ftp and gave only access to the specific directories, before you voice concerns!) I don't know all the ins and outs of Zope and there's probably something obvious I haven't done, but any help greatly appreciated, it's been driving me mad. I guess another option is to use our apache front for secure ftp access, but I wanted everything tidy, and besides I don't have root privileges on the server. Thanks in advance, Chris

oddity with zope and webdav
by David Bear 08 Dec '05

08 Dec '05

I have a zope instance listening on localhost. I use apache and fastcgi to reach zope. Now I would like to provide webdav. Since my apache is already doing ssl, I wanted webdav connections to also go through apache. when I use cadaver and connect to my zope zope through apache, all works well even though I have specified in my zope.conf file that webdav listen on localhost:8088 (it seems that cadaver is smart enough working through the fastcgi interface to just work). When attempting to using dreamweaver mx or windows webfolders to connect to zope I get an error. So I attempted to use an apache proxy pass directive to campture all urls at myzopeserver.edu:8088/webdav back to localhost:8088. This had no effect. cadaver was still able to work. Dreamweaver (using webdav site setup) and windows webfolders still failed. What deep magic do I need to make dav work through apache? ( would prefer to have all things go through fastcgi but I understand the trend is to use proxy-pass ) -- David Bear What's the difference between private knowledge and public knowledge?

Heh, it worked a treat! Blinkered as I was, I never thought to check the system temp dir; df-ing our filesystem tells me that today there is only 174M free on the root partition, where default /tmp is. That magical figure explains why I was able to download a 170M file but not a 180M file. Sorted. Big big thanks, Chris

Whoops. Sorry. Error log tells me it's a 'no space left on device' error: 2005-12-08T19:33:30 ERROR(200) SiteError http://ekhidna.biocenter.helsinki.fi/dali/downloads/180M.tar/index_html Traceback (most recent call last): File "/data/backup/Zope-2.7.0/lib/python/ZPublisher/Publish.py", line 100, in publish request, bind=1) File "/data/backup/Zope-2.7.0/lib/python/ZPublisher/mapply.py", line 88, in mapply if debug is not None: return debug(object,args,context) File "/data/backup/Zope-2.7.0/lib/python/ZPublisher/Publish.py", line 40, in call_object result=apply(object,args) # Type s<cr> to step into published object.

There's plenty of room left on our fs (hundreds of GB) so Zope isn't being allowed to use it at the moment. I'm asuming this is a Zope rather than local filesystem issue, but maybe I'm wrong; if it is a Zope issue, how I can increase standard cache size? We're not using a cache manager, yet... Thanks for your patience, Chris

Re: [Zope] Saving a Rendered DTML Document
by Asad Habib 08 Dec '05

08 Dec '05

Hello. The PHP script that I use relies on a path to locate the HTML file on the file system and since the DTML document is a Zope object, it does not have access to that. I also tried using a Zope File object as well as a DTML document that is part of a Local File System. Using a Zope File object does not work since the ouput of a rendered DTML document is text and providing the PHP script a Zope File filled with plain text does not work. The same goes for a DTML document that is part of a Local File System, once the document is rendered it is plain text. - Asad On Thu, 8 Dec 2005, Robert (Jamie) Munro wrote: > Asad Habib wrote: > >> Hello.

Can HTTP and WebDAV share port 80?
by Michael Dexter 08 Dec '05

Hello, It appears that Apache and IIS put both HTTP and WebDAV/HTTP traffic over the same port. Can Zope do the same? Why? Why not? Apprecaited, Michael.
