2.2 installation problem on Linux
by Ragnar Beer 16 Jul '00

16 Jul '00

Howdy! Zope 2.2 (linux2) installs and works fine using ZServer but for whatever reason there is no pcgi-wrapper built in the pcgi dir so that I cannot call Zope.cgi. I checked again and again but ./install doesn't give an error message. What am I doing wrong? --Ragnar

That would be great ! Perhaps you can also find a way to do this recursively ? Have a look at my recursive copier: http://zdp.zope.org/projects/zsnippet/snippets/DTMLTags/recursive_copier This does it the other way around, but it can be adopted to do what you need. It would be handy if you have many instances floating around. Maybe you can also do it easier with a ZCatalog search ?

2.2.0 and Membership ... NoGo
by Bill Anderson 15 Jul '00

15 Jul '00

Dunno what changed, but in 2.2.0b4 I could use Membership w/the latest ZPatterns just fine. In 2.2.0 when I try to add one, I get: "keyword redefined" errors. -- Do not meddle in the affairs of sysadmins, for they are easy to annoy, and have the root password.

hard dtml syntax problem
by Jerome Alet 15 Jul '00

15 Jul '00

Hi want to call ZopeFind to find all folders in the current folder which doesn't have got any subfolder. the following query works but returns all folders, even those which have got subfolders: <dtml-let myresult="ZopeFind(this(), obj_metatypes=['Folder'], search_sub=1)"> <dtml-in myresult> ... </dtml-in> So I play a little with the Zope Search Interface and I find that if I type in "not objectValues(['Folder']" (without the double quotes) in the obj_expr (Expression) field then this solves my problem. my question is: How to rewrite my ZopeFind with obj_expr="not objectValues(['Folder'])" ? I've tried with or without quotes (single, double and even triple ones), but with no luck: I've always got a Document Template Parse Error. What is the correct syntax please ? Actually I've added a test inside my dtml-in loop but I think it's stupid because I need the exact result length and I don't want to rebuild a list of matching results since the Zope Search Interface can do it. thanks in advance for any answer.

Optimization and speed
by Stephan Richter 15 Jul '00

15 Jul '00

Hello everyone, I write this mail, because I could not find anything useful in the archives: I have a pretty big site with quiet a big database (PostGreSQL) in the background. When a site loads I can tell that after about 5 seconds the site is ready to download. The site downloads quickly thereafter if I am on a T1, DSL or Cable Modem connection. But since most of our users have 28.8k and 56k modem connection, we have to optimize for them too. When accessing the site over a modem, it takes a long time to load the site and then it pops up all at once (in IE (AOL) and Netscape). Is there a way that I can send parts of the HTML as it is generated, so that the customer starts seeing information before the entire site is loaded. Our site is about 50% slower than our competitors sites (we are serving 62kB and the competitor has up to 203kB and is 50% faster!!!) which use PHP and ColdFusion. I know that Zope is not slower. I strongly believe it is the HTML output which is not optimized (we are going to speed up the DB connection very soon by dedicating a NIC only for the DB communication). Technical Facts: - Zope 2.1.6+PCGI+Apache - Virtual Hosts for HTTP and HTTPS - PostGreSQL 7.0 (DB size: 50MB), ZPyGreSQLDA, UserDB - ZODB threads: 4 - Web Server: Pentium 500, RH 6.1, 322MB RAM (not all used), 100 MBit NIC - DB Server: Pentium 500, RH 6.1, 322MB RAM (plenty left to use), 100 MBit NIC - dedicated subnet If someone could give me some tips where I should start looking for speed holes, please let me know. Do you think it is the DB which could be so slow and I should cache search results more, are there ZServer/Apache options I can set or anything else in Zope I should have a look at?

Delete property woes in ZClasses
by Paul Abrams 15 Jul '00

15 Jul '00

I noticed that when you delete a property in a ZClass, it doesn't actually delete the property in **instances** of that ZClass! This leaves properties lying around where they can be inadvertently acquired, causing problems that are difficult to trace. Has anyone gotten bitten by this, or know of a solution?

ZPygres connection problem
by Oleg Broytmann 15 Jul '00

15 Jul '00

Hello! I did an experiment (after having problems connecting Zope to Postgres) - I stopped ZServer and restared Zope in PCGI-only mode. I opened connection successfully! I stopped PCGI and restarted ZServer. I again got BadRequest (cannot connect to server). Anyone have an idea why Zope+ZServer cannot connect, while Zope-PCGI can? Deeper investigation did not reveal any difference - environments are the same, I can connect from command line, I can even import DB.py (from the Database Adapter) and connect through it from command line...
