cookie crumbler and error messages
by Paul Hendrick 22 Nov '05

22 Nov '05

Hi all, I'm using CookieCrumbler on a project which sits in / on one server, and /project in another. I'd like to secure a part of the site through *.metadata files so that users of a certain role can't access it. this is done and works well. however, when they try to access a part of the site which is secured, they're: a- given a log in popup prompt which they don't have the details for. and b- when they click cancel, they're given the dreaded zope barf screen. how can i either just redirect them to loggin_form or change the standard_error_message template to pick up these errors. i've tried changing the template that is in my zmi root, but none of the changes affect the screen when it appears, so i have no idea where to go from here. many thanks for reading! paul

Re: [Zope] unlinking stale socket?

Yes, so something must have killed the server and shut it down leading to the stale socket message. However I guess without further checking through the server logs I won't find out exactly why etc. On 11/22/05, J Cameron Cooper <jccooper(a)enfoldsystems.com> wrote: > > michael nt milne wrote: > > Ok, but Zope and Apache were serving nothing until I re-started Zope. > > The server had died for some reason > > Indeed.

Proxy setting for Zope and Products
by Renfer Serge (EDU) 22 Nov '05

22 Nov '05

Hello all, I'm responsible of a server (Debian Sarge) which has been put behind a firewall! I am strugling with proxy problems. For instance, CMFSin doesn't seem to work (for syndication slots in Plone), and LDAPUserFolder cannot reach an external ldap server. On the system itself, I have set the http_proxy environment variable (in .bashrc), it works fine for apt-get, for example, but it seems it has no effect on Zope! Do you have any idea if there is a way to inform directly Zope and all its products about a proxy in a simple way, or only products that are proxy-aware can be set to work in such an environment? Thanks in advance! serge

unlinking stale socket?
by michael nt milne 22 Nov '05

22 Nov '05

Hi My zopeinstance went down and I was getting an 'upstream server' unknown message from apache. On restarting zope from ./zopectl this was the message I got..... unlinking stale socket /home/zopeinstance/var/zopectl/sock,sleep/ No handlers could be found for logger 'root' Does anyone have any idea on how to prevent this at all, or what happened here? Thanks Michael

dtml-sqlvar problem with large strings?
by Joshua Burvill 22 Nov '05

22 Nov '05

Hello All, I am uploading and encoding files and then trying to insert the file content into a database. It works fine for small files (under about 20KB), but fails for larger ones with the error: Error Type: ProgrammingError Error Value: (-104, 'execute.isc_dsql_prepare: Dynamic SQL Error. SQL error code = -104. Unexpected end of command. ') See below for traceback etc. Using zope 2.6.4 on win32 with kinterbasdbda (not sure what version), firebird 1.0 It sounds like the sql command is getting trucated or something with the larger strings. Can anybody offer suggestions?

Check Interval
by Kozloski, Matthew E 22 Nov '05

22 Nov '05

I have a fairly large zope installation (thousands of users, ~130G combined zeo storages) and have been playing with the check interval. I have a single Xeon 3.2 that runs the show (both ZEO and Zope). I notice that when I set the check-interval at 826 (pystone / 50) the performance is horrible. In my case the lower I set the check interval, the faster the site is (quite significantly). Its not a problem - I'm just curious as to why this is/may be. From reading docs/postings online, it seems to me that the higher the check interval is, the faster the site should be (up to a point -- law of diminishing returns sort of thing). It is completely opposite for me and inquiring minds want to know... Thanks - Matt ________________________________ Matthew E.

<EMBED ...> problem
by David De Maeyer 21 Nov '05

21 Nov '05

Hi all, Got a weird problem with Zope... One of our user reported the following issue (under Zope 2.6.0): One html page makes use of the <EMBED> tag to show and play a MPEG video using the Windows Media Player. When we tried to edit that page for a minor text revision and saved that page, Zope did throw a 'Dynamic tag "embed" not allowed.'... and the change made to the page was lost. We then decided to remove the <EMBED> tag, just did a cut, and proceeded with the text revision. It worked but as one could expect we couldn't get the <EMBED> tag pasted into the document without having Zope complaining about that tag. Therefore a simple question: how do we get Zope to properly deal with this <EMBED> tag again? Is it is a configuration problem? Any idea?

Re: [Zope] probably a simple answer..

I'm thinking Kate means that she is writing to an Excel file on a Zope/Windows server, acting as a simple database, perhaps via ODBC. Kate can you clarify what you are trying to do? Thanks. -- Harlow Pinson Indepth Learning Email: hpinson(a)indepthl.com Phone: 505 994-2135 Fax: 505 994-3603

does anyone know of something like this
by Kate Legere 21 Nov '05

21 Nov '05

I develop for a library and wanted to know if there was a zope product that might accomplish what we're looking for before we build it ourselves. We have a number of book club sets that are loaned out to patrons for a 6 week period. The way in which this differs from our regular collection is that patrons can reserve a set by date rather than just joining a waiting list. Right now the way it works is almost beyond belief in it's complexity and archaic-ness. As I say, we can build an application that will handle this but it seems like it might be a common enough situation that if there was already something out there that we could just modify we might be better off doing that.
