Hey Ausum, Very cool! Improvements indeed! I don't care for the splitting of words into separate links "click vi/click ew" but everything else seems like a thoughtful fine-tuning of the UI. Hopefully these ideas will make it into an future release. Cheers Lee >From: Ausum <augusto(a)artlover.com> >I've uploaded pic snapshots hoping to explain them.

RE: [Zope] TUX and Zope? + ab results
by sean.upton＠uniontrib.com 03 May '01

03 May '01

Caching w/ TUX, AFAIK, isn't going to be as efficient as Squid. I think that likely the reason is that TUX is a webserver and not a cache, and that (if TUX can cache; I think it can just proxy!) the overhead to proxying likely mitigates a lot of the magic marshmallows in TUX like Zero Copy, checksum caching, etc - a network copy is going to add latency, and cache machinery is going to eat some CPU cycles. Somebody correct me if I am mistaken here. Tux might work well with ExtImage/ExtFile and TUX's machinery for serving some URLs and passing on others to another server (Apache, ZServer...). For predictable content, that is served over and over, seems like Squid in http accelerator mode is a better solution...

TUX is a linux only thing ATM, so any integration of the two would have to be some sort of add on to a vanila zope. > TUX 2898.55 Requests per second > AOLserver 603.14 Requests per second > Apache 502.51 Requests per second > Zope 60.57 Requests per second There are important reasons why the figures are so different. In the case of TUX, the kernel server tries to do as little work as possible to translate a request into data flying out the NIC. Zope, on the other hand, at the very least checks to see if the requester has permisson to access that object, and often looks after other things like acquisition, setting caching headers and obviously executing content generating code. The easiest way for Zope to take advantage of TUX would be to have a TUX based caching reverse proxy sit in front of the Zope server. All of the images and other static content window dressing for the site which will always be served up to everybody can have cache TTLs set so they quickly end up in the proxy, which can serve them up as fast as they can go. If you still want to crank more speed out of zope, the next thing to do would be to profile the steps needed to serve up requests for static content where having a permission system matters, and look into optimizing that.

rename objects permission
by Peter Bengtsson 03 May '01

Which permission is need to have to NOT get this message: "You are not authorized to access manage_renameObjects. " I have a role which is only supposed to be able to rename Image objects and add/edit properties of Image objects. This user uses a special interface I built and does not go /manage. Tried the: Change Images and Files ...permission but that wasn't it. Cheers, Peter

Catalog Anything Problem
by Bobby Mathew 03 May '01

03 May '01

Hi all I used the catalog anything manual to do have my sql data from postgres to be indexed into zope but i ran into trouble. I must warn you i am a newbie so it must be a very silly mistake somewhere. Let me explain what I did My config Linux OS Zope 2.3.0 Postgres 7.0.3 ZPyGreSQL DA The process Since i am a newbie i was not sure what you meant in the cataloganything doc when you said... ============= Setting Up the Catalog The first step in any search is to set up the catalog. There is no difference in setting up a catalog for "normal" searches and setting one up for a search of SQL data, so I'm not going to go into detail here on how to do that. Just make sure you have created a catalog with the desired indexes and meta data. ============== So i just used the chapter 9 reference that was provided earlier and i created a ZCatalog called Products. I was not sure what else to do so i just let the defaults remain as it is - the AnimalTracker example in chap 9 didnt seem relevant to me since i have no dtml methods to search for - only products info from the postgres. So i just didnt do anything further. I have a products table in the postgres rdbms that i want to search by title and description. So after this i created a zsql method called getProdtoCatalog under the ZCatalog itself - the query i used is SELECT prodid as Number, Title, Descr || ' ' || Title as PrincipiaSearchSource, 'Product' as meta_type, prodid as id, Descr as summary FROM products Now i went into the Find Objects section and searched for the getProdtoCatalog zsql method and added to the catalog Next i went and created the python script (again under the Products ZCatalog itself) and i called it catalogProducts this is the code inside for book in container.getProdToCatalog(): container.catalog_object(Product, '/learn/search/Products/'+Product.Number+'/proddetails.html') print 'Product #' + Product.Number return printed The moment i test it i run into trouble - Can any one help please regards bobby For the error message this is what i get.... =================== Zope Error Zope has encountered an error while publishing this resource.

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.
