No, for two reasons. Firstly Zope does seek over the pickle data, reading only the FileStorage transaction metadata. However it will be faster if those pickles are small, since more than one transaction metadata block will fit in one disk block. Further, it is more likely that the disk blocks will be available faster due to read-ahead in your OS. Secondly the internally-stored files will consume *more* ZODB objects - one object for each 64k of file size. This is necessary for the memory-reduction tricks mentioned earlier in the thread.

new user, having problems with apache
by jacob walcik 03 May '01

03 May '01

i'm trying to setup zope (2.3.1 built on redhat 7.0) and apache (the two are communicating via fastcgi) in a manner in which it can handle multiple virtual hosts. zope itself is working just fine via ZServer on port 8080, and here's what i have in my apache config: for fastcgi: LoadModule fastcgi_module libexec/mod_fastcgi.so FastCgiExternalServer /usr/local/apache/htdocs/zope \ -host localhost:8889 \ -pass-header Authorization for the virtual host: <VirtualHost 216.171.4.49> ServerAdmin jwalcik(a)iensemble.com DocumentRoot /usr/local/apache/htdocs ServerName milkman.iensemble.com ErrorLog logs/milkman.iensemble.com-error_log CustomLog logs/milkman.iensemble.com-access_log common RewriteEngine on RewriteCond %(HTTP:Authorization) ^(.*) RewriteRule ^/images/(.*) /usr/local/apache/htdocs/images/$1 [L] <Location /> Options ExecCGI SetHandler fastcgi-script </Location> </VirtualHost> like i said, my ultimate goal here is to be able to serve multiple virtual hosts from a single machine. i'd like everything past / at the url milkman.iensemble.com to be interpretted by zope, except for /images which will let apache hand out static images w/o having to bother with zope. now for the problem. with the configuration above, when i go to http://milkman.iensemble.com/ i get a "403 Forbidden" message from apache. if i go to http://milkman.iensemble.com/zope, i get the default zope index page. if i had the "Location" directive in the virtualhost set to /zope, i'd understand why this was happening, but since that's not the case, i'm not clear on what i've done wrong here. also, the rewrite rule doesn't appear to be working, but i can work on that another day... -- jacob walcik jwalcik(a)notwithstanding.org

how to know if an object is an objectmanager
by Jerome Alet 03 May '01

03 May '01

Hi, I'm writing something generic in a python script which has to test if an object is an objectmanager or not, since I want it to work with Folders but also with user defined types which inherit from objectmanager. How can I do that ? thanks.

Making users work
by Malcolm Box 03 May '01

03 May '01

Hi all, As a Zope newbie (sorry!), I'm deeply confused by how to make users work the way I want. The site I am developing is an "ideas" site, where people can vote on ideas and post new ideas. What I want to achieve is that everyone can access the content or vote anonymously, but to post they have to log in. As this is an intranet site, the WinNT domain controller already has a list of every possible user and a password, so I want to use this to authenticate who people are, and I certainly don't want to have to create and maintain a Zope user for each and every person in the organization! When people try to post without logging in, I want to send them to a page explaining the login requirements and giving them a login form, rather than popping up a http authenticate dialog. To say that I have no clue how to go about this is an understatement. I think there are three parts to this - one is the login form, the other is setting the right permissions on the posting form and the third is accessing the NT user database. I've looked at LoginManager, acl_users and various howtos, but I can't work out how to put it all together, despite my feeling that it's all there somewhere :-) So could anyone outline how to go about this - pointers to dtml source, howtos etc gratefully received.

Displaying the current date
by Andreas Pauley 03 May '01

03 May '01

Hi, How do I display the current server-side date with DTML? Thanks, Andreas. -- ... Any resemblance between the above views and those of my employer, my terminal, or the view out my window are purely coincidental. Any resemblance between the above and my own views is non-deterministic. The question of the existence of views in the absence of anyone to hold them is left as an exercise for the reader. The question of the existence of the reader is left as an exercise for the second god coefficient. (A discussion of non-orthogonal, non-integral polytheism is beyond the scope of this article.)

Browser sniffing for wireless devices
by Chris Muldrow 03 May '01

03 May '01

Anyone doing browser sniffing with Zope to determine whether a user is coming in with and HDML or WML-enabled phone? I've got some leads on this, but I REALLY don't want to have to check for every USER_AGENT available. Is there a good way to check and see A) if it's a WML device B) If not, if it's an HDML device C) If it's not, is it an HTML device? AND another wireless Zope conundrum. I'm serving some HDML pages from Zope. When I feed a Content-Type: text/x-hdml with the page, it doesn't show up on my Verizon Motorola 2260 phone. When I don't send the content-type, it does show up. The opposite is true on the Phone.com SDK phone browser--without a content-type, it chokes, but with a content type, it works. Any enlightenment? Thankee! -- Chris Muldrow, muldrow(a)mac.com

TUX and Zope? + ab results
by Jason Byron 03 May '01

03 May '01

This may sound silly, but do you think it would be feasably to get some more speed out of Zope by combining it with TUX (the linux kernel based web server) ? Maybe build the python interpreter into it ? I know, speed isn't important, abstraction is better, yada yada yada. It's just totally cool to see results like this, and I want to make Zope as cool as possible. 1000 requests, 100 at a time TUX 2898.55 Requests per second AOLserver 603.14 Requests per second Apache 502.51 Requests per second Zope 60.57 Requests per second bear in mind this is my piece of crap celery 700 with 128Megs RAM __________________________________________________ Do You Yahoo!?
