[OT ?... HTTP ?...] redirect W/ POST data
by Pierre-Julien Grizel 17 Oct '00

17 Oct '00

Hi, [This message may be off-topic.... Sorry...] I know how to do a RESPONSE.redirect with GET data (very easy : RESPONSE.redirect ('url?data=value&so_on=xxx'). But I'd like to do the same with POST data, that is, data that doesn't show up in the URL. I suppose there is a way to feed RESPONSE.headers with such data - although I'm not sure of it - but is there a better way (if there is a way...) to do this ?... Many thanks, P.-J. -- If the only tool you have is a hammer, you tend to see every problem as a nail.

Upgrade from 201 to 222
by Paul Zwarts 17 Oct '00

17 Oct '00

Hi all, I have installations of Zope, one for development and one for our live system. We had run Zope 201 on both machines for quite some time, and have just migrated the devshop to the latest Zope build 222. I have noticed that the import/export mechanisms work and I can import across both verisons, but before I was able to export an entire folder and then import it. Now from old to new, I get an error Error Type: TypeError Error Value: ('len() of unsized object', , None) What does this mean? I can still import single objects, but it is a major pain to import one by one, as there so many. Using an XML type doesnt work either because you cannot seem to apply that to a folder of objects either. Does anyone know about any issues that deal with this problem or am I missing something?

REQUEST.set size
by Paul Zwarts 17 Oct '00

17 Oct '00

Hi all, I am new to Zope but worked for 2 years in a dev-env called Uniface so Im fairly up to speed on Zope quickly. But I am having a problem writing data through a REQUEST.set that is larger than its apparent limit. (sorry can remember the exact error i get from Zope) What I am trying to do is collect in a field a large list of emails that are gathered in a dtml-in statement with a REQUEST.set('all', all + email) nested in the loop. While appending the namespace to store the data in PGSQL, i always get the size error which i assume is coming from the publisher saying that a the request can only have a byte size of 1800 bytes or so. Im not so hot with straight SQL because Uniface had its own methods, so Im not sure if I can append data directly to a stored field or if I need to continue trying to use the REQUEST.set. After the hundreth occurence in the IN, the namespace I use to store the appended data, so I cannot fully make a list of 2000 occurences. Any ideas? Sorry, no code to show what Im doing but it should be pretty easy to understand for all you veterans out there... TIA, -- Paz Oratrix Development BV http://www.oratrix.com GRiNS SMIL Editor -

Any help is appreciated!!! I tried your suggestion. The animGif works fine with every kind of HTML. I really think it's a Zope problem. Also the gif downloaded from Zope works with HTML outside Zope. The following doesn't work as well: Refer to the gif situated on your Zope server from a HTML file outside Zope. - Same problem... <html> <head><title>the title</title></head> <body><img src="http://localhost:8080/animGif"></body> </html> I also tried to name the animGif explicitely animGif.gif instead of animGif - guessed what? - same problem!

Zope in Windows is faster than Linux ???
by Aitor Grajal Crespo 17 Oct '00

Hi, I have a problem with Zope speed. I've done benchmarking in two machines, with the same hardware. (K7 700 MHz, 128 MB, 20GB HD) Windows machine : W 2000 Professional with Zope for Windows Linux machine : Linux RedHat 6.1, with Apache Server 1.3.12 and Zope 2.2.1 Windows 2000----------------------------------------------------------- Server Hostname: windows Server Port: 80 Document Path: /index_html Document Length: 486 bytes Concurrency Level: 25 Time taken for tests: 1.807 seconds Complete requests: 1000 Failed requests: 137 (Connect: 0, Length: 137, Exceptions: 0) Non-2xx responses: 864 Total transferred: 660974 bytes HTML transferred: 473471 bytes Requests per second: 553.40 Transfer rate: 365.79 kb/s received Connnection Times (ms) min avg max Connect: 0 0 10 Processing: 11 42 356 Total: 11 42 366 ----------------------------------------------------------------------------------- Linux--------------------------------------------------------------------------- Server Hostname: linux Server Port: 8088 Document Path: /Contactos Document Length: 396 bytes Concurrency Level: 25 Time taken for tests: 7.688 seconds Complete requests: 1000 Failed requests: 0 Total transferred: 595000 bytes HTML transferred: 396000 bytes Requests per second: 130.07 Transfer rate: 77.39 kb/s received Connnection Times (ms) min avg max Connect: 0 8 224 Processing: 102 181 54 Total: 102 189 278 ------------------------------------------------------------------------------------------------------- There's a big difference in the number of requests per second, four times more in the Windows machine.

Does Zope security provide a way of restricting what objects are listed to an authenticated user inside the Zope 'manage' interface? I'm getting my head all twisted up over this security / proxy roles /local roles lark. Thanks, seb

Socket.error problem
by Ronald L. Chichester 17 Oct '00

17 Oct '00

I'm getting the exact same socket.error message that appeared on this list in March, 2000. (See the attached problem.txt file.) Specifically, this is the error message that I get when I start zope. The person who kindly identified the problem didn't provide a solution. I have my netstat -a results attached as netstat.txt. Could someone tell me how I can resolve this port conflict? Incidentally, I'm using Mandrake 7.1 in a fairly standard configuration. Thanks in advance, Ron ./. This is the reply that was provided to the first person who encountered this problem (and submitted it to the list): <MESSAGE> You have another process that is "bind" to port 98... this is the registered port for "tacnews". try "netstat -a" under the shell... ----- Message d'origine ----- De : Ulf Byskov <ulf.byskov(a)comptel.com> À : <zope(a)zope.org> Envoyé : lundi 13 mars 2000 11:28 Objet : [Zope] socket problem > When I try to start Z Server i get the following error messages: > > File > "/WWW/Docs/product_development/teams/AMD_framework/dev/Zope/ZServer/medusa/a syncore.py", > line 205, in bind > return self.socket.bind (addr) > socket.error: (98, 'Address already in use') > > > I don't use the number 98 in any address or port (http=80, ftp='' and > monitor='') > so what could this error be about ? > > > </MESSAGE> [nobody@localhost Zope-2.2.2-linux2-x86]$ ./start ------ 2000-10-08T-5:31:03 PROBLEM(100) ZServer Computing default hostname ------ 2000-10-08T-5:31:03 INFO(0) ZServer Medusa (V1.16.4.3) started at Sun OCt 8 00:31:03 2000 Hostname: localhost.localdomain Port:8080 Traceback (innermost last): File ?/usr/local/Zope-2.2.2-linux2-x86/z2.py?, line 634, in ? logger_object=lg) File "/usr/local/Zope-2.2.2-linux2-x86/ZServer/FTPServer.py?, line 619, in __init__ apply(ftp_server.__init__, (self, None) + args, kw) File ?/usr/local/Zope-2.2.2-linux2-x86/ZServer/medusa/ftp_server.py?, line 725, in __init__ self.bind ((self.ip, self.port)) File ?/usr/local/Zope-2.2.2-linux2-x86/ZServer/medusa/asyncore.py?, line 242, in bind return self.socket.bind (addr) socket.error: (98, ?Address already in use?)

DTML Method not working
by Ronald L. Chichester 17 Oct '00

17 Oct '00

I took some code that was in the (work-in-progress) O'Riley book on Zope. In that example, then had a DTML Method used for identifying folders and hyperlinking to them. The code is as follows: <ul> <dtml-in expr="objectValues('Folder')"> <li><a href="&dtml-absolute_url;"><dtml-var title_or_id></a><br></li> </dtml-in> </ul> The problem is, it doesn't work. I know the method is being invoked because there is some other text that is indeed being inserted. Moreover, there are sub-folders in the folder that calls the method. Does anyone know what the problem is? Is it a permission issue. The standard_html_header and _footer, show up just fine, along with logos and such. The only part that isn't showing up is the stuff that was supposed to be generated by the <dtml-in> block. Any hints? Thanks in advance. Ron ./.

Newbie question : ZopeTime & permissions
by Aaron Straup Cope 17 Oct '00

17 Oct '00

Hi, My name is Aaron. I am trying to set up zope with (atleast) three roles : manager, admin, user. I'd like to give the last two the bare minimum Security permissions possible and adding them as needed later on. My problem is that I can't seem to figure out, specifically, which permissions to give a user that will allow them to read ZopeTime(). (see below) For the admin user, I have set the Access content information and View * options globally. I've tried guessing at some others, but there are alot of possible combinations to try so I thought maybe I would just ask. Related, is there a detailed description of the default Security settings? I've checked the mailing lists and the Zope docs and if it's there, I guess I missed it.
