Not at all too good to be true. I use Hurrah for one of my sites. They are fast, prompt, helpful, and knowledgeable about Zope. I think they are the best deal running in Zope hosting at this time. -- Kit O'Connell Zope Administrator kito(a)clearcommerce.com 'yes is a world & in this world of yes live (skilfully curled) all worlds' - e.e. cummings -----Original Message----- From: Lee Marzke [mailto:lmarzke@kns.com] Sent: Friday, March 16, 2001 6:43 PM To: zope(a)zope.org Subject: Re: [Zope] Zope hosting Anyone have experience with http://www.hurrah.com/ ?

RE: [Zope] MS Explorer no longer shows the management interface.

The weird part of all this that it worked just fine until I put in the security patch. When MS puts out a new security patch will they break the IE connection to ZOPE again? Our shop is stuck, by official decree, to using IE but they haven't found a way to force us not to use Netscape on the Linux servers yet. (Possibly because we haven't told them we are using Linux?) Thanks, I will have to upgrade to 5.5 and warn my Zope managers about this problem.

RE:ZCatalog update question
by Darin Lee 19 Mar '01

19 Mar '01

Gari, You must call <dtml-call reindex_object> in any of your methods that operate on data (constructor, edit functions etc.) in order for the object to be automatically updated in the ZCatalog. Simply inheriting ZCatalog as a base class is not enough. Also, make sure when you are defining your base classes to include ZCatalogAware FIRST. Good luck, -Darin

Zope vs. other app servers. Any comparison available?
by Satheesh Babu 19 Mar '01

19 Mar '01

Hi, We use Zope a lot. However, there are some schools of thought that since MacroMedia has bought Allaire, it is going to be *the* web app development platform (personally, I think you can't compare Cold Fusion to Zope). So, are there any web sites that compare Zope vs. ASP, PHP, Cold Fusion, Java app servers? If this is "suite" friendly, better! Even other wise, if you've any pointers to existing documents, that would be of great help. TIA V. Satheesh Babu sbabu(a)tnc.org

Re: Fwd: [Zope] Using psycopg connections directly

Scavenging the mail folder uncovered Paolo Comitini's letter: > Because psycopg is advertised as having a per-cursor commits, initially I > just did the same thing in my code as a Z SQL Method would do: call the > database object for a connection and run query() on it.

This is probably due to the fact that the > psycopg DB class commits on the connection, not on the cursor it used. if you want to use the per-cursor commit extension of psycopg, you need to call the .commit() method on the *cursor*. calling it on the connection will commit on all the cursors derived from the connection. > So I now grab a cursor, and register that (inside a wrapper) with the > transaction manager, for every query.

There's probably some interaction between what I do and psycopg > that I don't understand. note that psycopg open one connection for every cursor (that will change in the near future) so, if you don't set a maxconn value on the connection but keep creating cursors, you'll finish with an hight number of phisical db connections (maxconn is about 32 by default.) > Would anyone have a suggestion as to how I could use psycopg Z Database > connections from Python code in such a way that everything works smoothly? > What's the Zope model anyway - does it instantiate one Z connection per > thread or do all the threads use the same connection and should the > connection figure it out by itself? mmm... i think that zope instantiate a connection for every thread. in the psycopg case, every zope thread gets one connection and one cursor. hope this helps, ciao, federico -- Federico Di Gregorio MIXAD LIVE Chief of Research & Technology fog(a)mixadlive.com Debian GNU/Linux Developer & Italian Press Contact fog(a)debian.org Qu'est ce que la folie?

MS Explorer no longer shows the management interface.
by Echlin, Michael 19 Mar '01

19 Mar '01

Hi, This morning I installed a few upgrades to MS 98 (Internet Explorer 5.01 Service Pack 1) and when I go to my Zope site I can no longer see the management pages. The right frames are displayed and the navigation tree, but instead of the management screen for a folder I get the view contents. Any Ideas?
