RE: [Zope] Single authentication for several servers
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 07 Mar '03

I've faced a similar situation (Though not with Zope at all actually) ... The way I prefered was to set the cookies for both domains in one pass, by using cascading scripts on each server, so that when you log in to one, it sets cookies for itself, and then transparently calls a script on the other site asking IT to set cookies for itself. This of course depends on both sites using the same cookies, which may or may not be the case depending on exactly how you authenticate. But it's an option, Cheers, J.F. -----Original Message----- From: Thierry FLORAC [mailto:thierry.florac@onf.fr] Sent: Friday, March 07, 2003 12:57 PM To: zope(a)zope.org Subject: [Zope] Single authentication for several servers Hi, I'd like to setup this environment : - I have a first site, handled by Zope, behind an Apache server and rewrite rules. Authentication on this server is done throught an LDAP server with LDAPUserFolder. - I have a second site on a different server, handled by Apache+PHP. Authentication on this server is done throught the same LDAP server, so with the same login/password, throught mod_ldap. My problem is that when I switch from the first server to the second, I'd like to avoid a second authentication. So my idea was to access to server2 throught "http://www.site1.com/site2", with Apache handling a new rewrite rule in proxy mode. Do you think that it should work (I can't test easilly before asking you !!) ?? Of course : - I don't have any SSO solution ; - I can't rebuild my PHP application with Zope before several months :-(( (but I can update scripts to take the new access path into account). Thanks for any help or advise.

COMObject product question
by Micheál Healy 07 Mar '03

07 Mar '03

Hi, Has anybody used the COMObject product package much? I have been trying on and off to put data into an existing Excel template and display the result within the browser. I can do it using an external method to populate the spreadsheet and save it, then using the LocalFS product to retrieve the file and return it to the browser. This is all fine, but I was wondering if there wasn't a better way. Does anyone know if it's possible to return the Excel file to Zope as a COM object (without having to save the file to the local filesystem of the server) and just sent it to the browser as binary content, setting the content type. Does the COMObject product work like this? Thanks, Micheál Micheál Healy Engitech Ltd. 01 6204 516

The problem is created by setting the "save_interval" greater than 4. After changing the setting the error message went away.

ExternalEditor has problems with editors that detach from their parent process. I think the only way around this is to have an editor-specific plugin to deal with this. I think there is one for Word, but not for notepad. Try MSWord or gvim instead, or consider figuring out how to make a plugin work for the editor of your choice. I haven't done this, but I think there is info you can either google for or search list archives.

Thanks for the reply. I am baffled because I have the same setup. If I use notepad.exe instead of gvim.exe I also get the same message. It must be a configuration issue specific to my machine.

ZODB: Are all handles closed?
by Ulla Theiss 07 Mar '03

07 Mar '03

Hello list, in our product (and additionally in an other process) we use separate ZODB-Storages. Opening and closing the ZODB several times the number of file-handles increases. We have separated the multiple openings and closings to the following code. It shows the increasing of the handles clearly. Have we forgotten to clear anything or made anything wrong? If not, has anybody an idea, how to fix or work around the problem. ----------------------------------snip------snap--------------------- from ZODB import FileStorage, DB for i in range (1,100): storage=FileStorage.FileStorage("TestZODB.fs") db = DB(storage) db.open() print "Open" db.close() print "Close" storage.close() ----------------------------------snip------snap--------------------- Enother nice behaviour we can achieve with the following code: ----------------------------------snip------snap--------------------- from ZODB import FileStorage, DB storage=FileStorage.FileStorage("TestZODB.fs") db = DB(storage) for i in range (1,100): db.open() print "Open" db.close() print "Close" storage.close() ----------------------------------snip------snap--------------------- It works about seven times. Then the programm hangs completely. Much thanks in advance, Ulla.

Zope 2.6.1 changed default number format
by Ed Crewe 07 Mar '03

07 Mar '03

Hi, Rather than do uneccesary work can I just enquire about whether recent numeric handling changes in Zope 2.6.1 are intentional or might they be reversed? Zope 2.6.1 has changed the default dtml number display format from integer to one decimal place floating point. This breaks any sites that use dtml integer display. Was this a deliberate change? If so what is the recommended solution for replacing dtml such as <dtml-var link_id missing="0"> Should all dtml integer rendering be replaced with <dtml-if "_.has_key('link_id')"><dtml-var link_id fmt="%i"><dtml-else>0</dtml-if> or is there an economical way of displaying an integer in dtml?
