ANNOUNCE ZEO 0.3 Released
by Jim Fulton 31 Aug '00

31 Aug '00

A new release of Zope Enterprise Objects (ZEO) is available at: http://www.zope.org/Products/ZEO. This release fixes a bug that caused spurious conflict errors and that could eventually make it impossible to make changes without restarting a ZEO client (e.g. Zope process). The release also has two enhancements when running the ZEO server on Unix: - When the storage server start script is run as root, the script will switch to a different user (nobody by default). There is a new '-u' option that can be used to specify the user. - The storage server will gracefully close served storages when the server is killed with a SIGTERM or SIGHUP. If a FileStorage is being served, then an index file will be written. If you encounter problems with ZEO, please report them using the ZEO issue tracker at: http://www.zope.org/Products/ZEO/Tracker.

Re: [Zope] FSSession problems...
by Hung Jung Lu 30 Aug '00

Curtis, Could you describe how often does the problem happen? How many session users goes to the site? You mentioned about a month of public usage. During that month, did you have one single incident? How many sessions happened during that month? All key-based session management systems are intrinsically unsafe, since other people can tap into your session, with non-zero probability, if the key-length is finite. The only hope is to make the key long enough, so even if the hacker has a supercomputer, it would still take him/her the age of the universe to crack into your website. One thing I mentioned to Pavlos (and/or Anthony Baxter?) before is that the key lengths of their cookies are a bit too short. For my HappySession product (another session management product, which is RAM based), I cranked up the key length to 128 alphanumeric char key, exactly because I wanted no key collision for a long long time. :) Another thing I observed during the development of HappySession was that on Linux (and Debian) server systems, I had problem with deleting the cookies of the clients. (No problem with NT server.) At the end, I chose not to delete cookies but instead setting their values to blank, when the session expires. It was a weird problem, I did not know why I couldn't delete client cookies (maybe it was a mistake on my part), but I chose the simple way out by setting the cookie to blank. And it worked fine. So instead of detecting the presence of the cookie alone, I detected the presence AND whether the cookie was blank. regards, Hung Jung _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Newbie SQL problem: Query Error: Cannot render query template
by Farrell, Troy 30 Aug '00

30 Aug '00

Hello. I am running Zope as a service on NT4WS. I have multiple MS Access databases connected to different ZJetDAs and I am not able to modify the data in them with SQL statements. For example, INSERT INTO test VALUES (<dtml-sqlvar value_one type=string>, <dtml-sqlvar value_two type=int>) returns the error "Query Error: Cannot render query template". Can you tell me what the cause is. I think it might be a permissions problem, but I have everything wide open and I can't figure it out. Thanks.

Re: [Zope] Apache: mod_perl, mod_rewrite, prefix
by Hung Jung Lu 30 Aug '00

30 Aug '00

>(1) I have mod_rewrite statically >(2) I have mod_perl statically >(3) prefix is /usr/mydir Okie, I figured it out. So I'll reply to myself. :) By the way, I am on Linux platform. So the appropriate commands are (1) Download latest apache and mod_perl. Unzip and untar them. (2) Place the untarred mod_perl-1.24 into your apache_1.3.12 folder. (3) cd into the mod_perl-1.24 folder. (4) perl Makefile.PL \ USE_APACI=1 \ APACI_ARGS='--enable-module=rewrite' \ APACHE_PREFIX=/usr/mydir (5) make (6) make install (this will install the the httpd executable but not override the existing httpd.conf file. If you want to play safe, make a backup of the httpd executable before installing the new one.) C'est tout!

Reminds me some strange behaviour i had while redirecting to an URL with a variable. When i changed the redirect with "hard coding" the URL this disapeared.

Apache: mod_perl, mod_rewrite, prefix
by Hung Jung Lu 30 Aug '00

30 Aug '00

Hi, Although this is more an Apache question, I would guess that a lot of Zope users have gone through exactly the same problem I am going through, so I might as well try it out here. As you can probably tell, I am trying to hook up Zope and Apache via PCGI. The thing is, I need also mod_perl, and my Apache root prefix is non-standard (not /usr/local/apache). I want to build Apache from source such that (1) I have mod_rewrite statically (2) I have mod_perl statically (3) prefix is /usr/mydir Now, those are three requirements, and things got too complicated. I know how to do (1) and (2) together, I know how to do (1) and (3) together, but I still fail to do (1)(2)(3) all together. Anyone cares to share their experience? I want a final httpd executable, so that I can simply copy and replace my current copy of apache. I have read: http://perl.apache.org/guide/install.html but I am still a bit confused. Thanks, Hung Jung PS- I think mod_perl is an example of big failure when it comes to installation, since it tries to control and override the apache installation process. What a mess! In comparison Zope product installations are as easy as drag and drop. _________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Case Studies (good!)
by J. Atwood 30 Aug '00

30 Aug '00

Does anyone else love those case studies? I have was grinning ear to ear reading the new one about replacing all Notes/Domino (which I know and respect) with Zope. I would love to see more studies on all sorts of different sites (big, small, database driven, not). They are also really useful for those of us who need to try and convince management that 'others are doing it too', which is a cold hard fact of the corporate world. I would love to see much more (weekly) as well as more on hardware and hits. Keep up the great work DC. Cheers, J
