zope 'hangs'
by Stephan Herschel 10 Dec '01

10 Dec '01

Hello, We have got a funny problem in Zope: if user A issues a long-running query user B also has to wait in the meantime - zope just waits for A's query to finish. We are using interbase as our database and GV Interbase Database Adapter 0.9.6 on a linux system. In the README it says 'threadsafety ... is set to 1 - threads may share the module but not connections' Somehow i suspect the problem lies there. Can anyone give me a hint on this problem? Thanks in advance, Stephan

Hello, I tried to make the Zope related Debian packages for the future Debian 3.0 distribution up to date. When I tried to install the product Zope EMarket I've got the following Traceback: Product at /Control_Panel/Products/EMarket Import Traceback Traceback (most recent call last): File "/usr/lib/zope/lib/python/OFS/Application.py", line 563, in import_product product=__import__(pname, global_dict, global_dict, silly) File "/usr/lib/zope/lib/python/Products/EMarket/__init__.py", line 12, in ? import EMarket File "/usr/lib/zope/lib/python/Products/EMarket/EMarket.py", line 23, in ? from Globals import HTMLFile, MessageDialog, Persistent, DateTime ImportError: cannot import name DateTime I'm using zope version 2.4.2 zpatterns version 0.4.3p2 Any fix for that problem available? Kind regards Andreas.

e: [Zope] using mysql LOAD command to store values into table from zopemgt screen (is it realistics?)
by hamzatk＠3dresearch.com 10 Dec '01

Hello Nitin, Please I need your utmost support to get this done. First and foremost i am new to php, infact i have never lay my hands on it before. Please how do i get this done. I wouldn't mind if you can tell me in a layman's lang. Then my situation is that i have limited access to the Mysqlserver at the remote site. . where do i get PhpMyadmin? I am desperate to get this done. Bcos I have wasted alot of time trying to get it solved. What i was actually looking for was to use SSh (through telnet) then my host is not ready to give me that kind of priviledge. I wiil be glad if you can put me through. or is it possible to achieve this from zope mgt interface through mysql methods or python script. I expect the LOAD command to work at ZMI since it is one of the MySQL command just like INSERT command. Best Regards.

Adding files
by Derek Simkowiak 10 Dec '01

10 Dec '01

All, I have a few (easy?) questions wrapped into one email here, so I apologize for that. But I haven't been able to find the necessary info in the docs, www.zope.org, or "The Zope Book". My client wants to publish files to Zope using MS-Windows "drag'n'drop". They want to drag entire directory trees and drop them into Zope. Publishing files individually (and manually creating all subdirectories) through the web admin interface is too slow. I see two possible solutions: 1. Use Samba to "share" a filesystem via SMB, and then use some kind of 3rd-partyProduct that lets Zope import a filesystem tree. The client would drop files to the Samba share, and those files would magically appear in Zope. (Can anyone point me to such a Product?) 2. Use either WebDAV or FTP with Windows XP's native support for those protocols. Windows Explorer would make the Zope server appear like any share, but use WebDAV. This would require Windows XP or an Explorer add-on such as FTPDrive (which makes FTP sites appear like a drive). Have I missed any possibilities? My next question is: When I create a object in Zope, I have to select the type (i.e., the "Select type to add..." dropdown). Is it a DTML Document? DTML Method? An Image? When adding files to Zope with WebDAV or FTP, how does it know what "type" to make those new files? If I upload 'spam.html', will that become a DTML Method? A DTML Document? What if I want .html files to be ZPT pages instead? Does it use file extensions, or MIME types, or magic numbers? Finally, related to the above question, my client wants to use Zope to publish LARGE files. Video files, DVD images, etc. (it's a video shop). I've looked at the Product ExtFile (w/ExtImage), which claims to store only meta-data in the Zope ODB, and not the file contents itself. With ExtFile, the contents reside as regular filesystem files, thus not plugging up the ZODB when you have very large files. Frankly, I'm a bit surprised that this is not standard Zope architecture. Anyway, I want to make sure that these huge (300MB to 2 gig) don't bring Zope to a halt. Other than ExtFile, are there any recommendations? If files are uploaded with WebDAV, how do I make it default to "type" ExtFile? Thank You, Derek Simkowiak dereks(a)realloc.net

Hi all I'm sure this is dead simple, but I'm not getting it. How do I do this? :: brains = catalog( Status != 'dismissed' , meta_type = 'Reminder' ) Specifically, that "!=" inequality condition. I want all reminders that aren't dismissed. Regards, Jean

CookieCrumbler and Apache/IIS
by Jeffrey Robinson 10 Dec '01

10 Dec '01

Hello folks; This question may have been asked before, but I don't believe I've found an answer to it. I have been using the CookieCrumbler product to give me nice web-based login/logout facilities, and am quite pleased with how it works when I access Zope directly. Though now that I'm trying to get things into more of a production environment I'm running into a bit of a problem... My initial work with one company had Zope behind IIS using PCGI and no matter what it seemed that users could not login when going through IIS. Though if they bypassed the server and went directly to port 8080 there was no problem at all. Now, I have a setup (on Linux) using Apache and rewriting URLs (for Virtual Hosts) to access specific folders in Zope ( using the instructions based on: http://www.zope.org/Members/anser/apache_zserver ). The access and administration passing through Apache work fine; the admin interface is entered into by using the standard Zope (HTTP) authentication... but no matter what I do it seems like I can't get the CookieCrumbler working behind a webserver! Have other folks had difficulties with this before? Can it work, or should I be using a different method of authenticating/tracking visitors? Thanks in advance; Jeff Robinson Graphic Designer Motor Coach Industries

Hi; I have this code: <dtml-if expr="URL[-(_.len('_frame')):]=='_frame'"> <dtml-call "SESSION.set('select_blueline_temp',select_blueline(_.None,_))"> <dtml-if expr="error_type == 'SessionNotFoundError'"> <dtml-return happysession_exception> <dtml-else> <dtml-return index_frame> </dtml-if> </dtml-if> that produces a traceback stating *global error_type is not defined*. Huh? I thought this was part of the distro! What do? TIA, BenO

exUserFolder - users updating their passwords
by Heimo Laukkanen 10 Dec '01

10 Dec '01

Hi all, my system still runs 2.3.3 for a while - and there is also exUserFolder 0.8.x installed. Now I noticed a strange thing happening from time to time. When users update their passwords - their old password come back after a while. My users have not been able to say yet, how much time it takes -- but that it happens. I haven't yet tried to update the exUserFolder - installation. I will try that during this week. Just had a thought if anyone else have had same experiences. -huima
