ciao Fabio, I use an external method based on the one described in this how-to: http://www.zope.org/Members/Ioan/FastSiteSearch to achieve this. However, it requires a lot of text to be in metadata and may be the cause of my frequent memory errors and Zope crash/restarts. In fact if anyone could point me in the direction of a solution for that, or a source of info on the metadata-memory issue I would be very grateful ;-) Ken >Thus spake Fabio Rolando: > >I have a collection of docuements that are indexed and >automaticaally handled by Catalog.

Is there any >product that can help me impementing this funzionality?

this().aq_explicit() & this().document_src() - what is the relationship?
by Fabio Rolando 05 May '03

05 May '03

Hi, I have a ZClass with DTMLDocument as base class. I made a DTMLMethod to display the contents of the Object with <dtml-var "this()"> but I got the HTML tag escaped (i.e. < transformed in < and so on) so I changed in <dtml-var "this().document_src()"> and it worked correctly, with the HTML rendered, but I got problems with unauthenticated user, getting the message Error.... document_src not allowed in this context. So I changed (practically by mistake!) to <dtml-var "this().aq_explicit()"> It works correctly with no authentication problem! Now I am happy, yet a bit frustrated because I could not find any document around helping me understanding the reason WHY it does work now! :-| I don't even understand what is the relationship between aq_explicit() and the contents of the document. Any pointer, suggestion, hint, whatever...? Thank you so much Fabio

Is Zope susceptible to denial of service attacks?
by Toni 05 May '03

05 May '03

Helo every body. I'm testing zope (2.5.1) and i would like to know your experience about this stuff. Is zope suceptible to dos attacks? Or is better to run behind Apache/Squid? Another subject: I have detected with netcat http connections that Z2.log file hasn't logged, How can it be? ..........................................................

RE: [Zope] Using Internal exchange server email and Zope Mailhost

Hi, The email guy was out last week, this morning he said he turned smtp relay off for security reasons. Thanks. -----Original Message----- From: Troy Farrell [mailto:troy@entheossoft.com] Sent: Friday, May 02, 2003 4:57 PM To: McDonnell, Larry Cc: zope(a)zope.org Subject: Re: [Zope] Using Internal exchange server email and Zope Mailhost Larry, I would first run a manual SMTP session via telnet to your mail server. If that works alright, then I would use a packet sniffer to figure out when Zope is getting this disconnect from the smtp server.

Hi. I have a collection of docuements that are indexed and automaticaally handled by Catalog. My search results interface now give information that are stored in the metatypes of the documents. I have to modify the results interface so that a short quote of the matching documents is displayed with the matching words in evidence. Something like the Google results page. Is there any product that can help me impementing this funzionality? Thank you all Fabio

XML + HTTP == XML-RPC
by Toni Andjelkovic 05 May '03

05 May '03

Hi, I'm using Zope 2.6.1 with ZServer listening to port 80. I need to receive XML documents via HTTP POST. Unfortunately, ZPublisher assumes that POST requests with a content-type of "text/xml" must be XML-RPC, so it tries to parse them accordingly, which fails. I'd be grateful for suggestions on how to solve this elegantly. Thanks, -- Toni Andjelkovic <toni(a)soth.at>

Zope and permissions in Linux
by Fernando Martins 05 May '03

05 May '03

I'm moving my web site from OS/2 to Suse 8.2 and I've a few questions to understand how to deal with the permissions. The installation creates a user called zope which owns the directory var/gadfly and also var/gadfly/demo. I tried to create another directory, gadfly/db to put my database files in. However, I could not 'su zope' as I didn't know the password given at install time. I was not present during the Suse install but my colleague doesn't remember having seen a password for Zope (as stated in a couple of pages online, the install script outputs a password). Then, I went root and I gave zope a new password. Only afterwards, I realised this was probably a mistake. What happens if I restart Zope? Anyways, even after changing the password i could not su zope. Nothing would happen. So to create var/gadfly/db I went root and then chown the directory to zope. Was this the correct procedure? Also, I've a little External method file to install. Should it be owned by root or by zope? Any good piece of advice regarding zope security in Linux? (it's an internal web site but still) Thanks, Fernando

Unexpected Squid problems
by Wankyu Choi 04 May '03

04 May '03

Hi everyone, I recently set up a Squid frontend before ZEO server + a single ZEO client. Specs: ZEO: 2.0.1 Zope: 2.6.1 Storage: DirectoryStorage 1.0.1 Platform: Redhat Linux 8 with all erratas applied up to this date Kernel: 2.4.20 + aa1 patch Squid: 2.4.STABLE7-4 I successfully set up a cache peer thanks to Toby Dickenson's excellent howto: http://www.zope.org/Members/htrd/howto/squid After running Squid for about a week, I found something really annoying about this setup: Squid gives up on the ZEO client for dead when Zope is packing the ZODB. And the Squid manual says it'll query even a dead peer from time to time to see if it came alive, but that never happens. I'm running z2.py with --icp 3130. And the problem occurs only when packing is in progress. It seems when packing is in progress, Zope's taking too long to respond to queries sent from Squid. I tried adjusting timeout values as high as 20 seconds to no avail. Going for higher values looks really stupid. I have to restart Squid again and again. I even came up with a little shell script to grep Squid's cache.log every 10 minutes and restart the daemon if it finds a string containing 'Detected Dead Parent' ( and, of course, empty the log ). But it's so kludgy a solution :-( It gets worse. Last night, I added two more ZEO clients to this setup, and now I have three clients in total. Whenever the packing script runs, all three ZEO clients are pronounced dead by Squid and during this time no service is available. The 10-minute cron job restarted Squid as many as 5 times. The packing script is started by a single ZEO client. Anyone experienced a simliar problem? Here goes another. I haven't been able to track down the cause of this problem but having three ZEO clients takes much longer to serve ZODB than having a single ZEO client. For example, it used to take an average 1 second rendering a CMF document when I ran a single ZEO client, but it now takes an average 2.5 seconds with three clients. Plus, it generates conflicts too often. The slow performance, however, is not directly related to read conflicts since even with no conflict, the overall performance is way too bad. All three ZEO clients are 2-way/4-way Xeon servers with RAM to burn: 2G. Nothing is hogging any of their resources. All three of them are hooked up with ZEO server/Squid frontend in 100M bandwidth. Any ideas? Thanks in advance.

Plone kills Zope
by pelayo 04 May '03

04 May '03

Hello, I'm working with the testing Debian packages of zope, cmf and plone, and I have some problems. 1) When I start zope there's no errors but, if I stop it I get: "stopping Zope...done (Zope was not runnig)", and, in fact, it's running. If I restart it, I get: "Zope is currently restarting (or something very strange)". The log file doesn't show anything interesting : ------ 2003-05-04T18:47:29 INFO(0) zdaemon Started subprocess: pid 27665 ------ 2003-05-04T18:47:31 INFO(0) ZODB Opening database for mounting: '144004256_1027354084.930550' ------ 2003-05-04T18:47:31 INFO(0) ZODB Mounted database '144004256_1027354084.930550' at /temp_folder ------ 2003-05-04T18:47:31 INFO(0) Zope Default Object Creation /usr/lib/zope/import/Examples.zexp examples import file could not be found. ------ 2003-05-04T18:47:31 INFO(0) ZServer HTTP server started at Sun May 4 18:47:31 2003 Hostname: volatil.gbt.tfo.upm.es Port: 9673 ------ 2003-05-04T18:47:31 INFO(0) ZServer FTP server started at Sun May 4 18:47:31 2003 Hostname: volatil Port: 8021 ------ 2003-05-04T18:47:31 INFO(0) ZServer PCGI Server started at Sun May 4 18:47:31 2003 Unix socket: /var/lib/zope/var/Z2-pcgi.soc ------ 2003-05-04T18:59:13 INFO(0) Z2 Caught signal SIGTERM ------ 2003-05-04T18:59:13 INFO(0) Z2 Closing all open ZODB databases ------ 2003-05-04T18:59:13 INFO(0) Z2 Shutting down 2)In spite of these menssages, if I use "basic Zope" and CMF, Zope seems to work right. But when I use Plone, Zope dies suddenly. Exactly, I get nothing when I point my browser to Zope, but if I try to restart it, the following text appears: "starting Zope...Only Z2 running! This should not happen. Please stop and restart Zope" I stop (and again this message:"zope was not running") and start it, and everything's OK until I use Plone again. Can you help me? Thanks Pelayo Beltrán
