ANNOUNCE: Zope 2.2.4 (final) released...

29 Nov '00

Hello all, Zope 2.2.4 has been released - you can download it from Zope.org: http://www.zope.org/Products/Zope/2.2.4/ This release supercedes the 2.2.3 release, which had an error that prevented permissions from being acquired correctly. Until the testing infrastructure that has been started in the 2.3 CVS is more mature and there is a useful regression test rig, we'll be planning for at least one (short) beta period for third-dot releases. This bug-fix release contains the fixes for all released Hotfixes to date, as well as fixes for a memory leak in the Acquisition module, various ZCatalog fixes and a fix for the infamous "__call__" bug. It also contains a fix for a problem in header parsing in the dtml sendmail tag that has affected some users recently. The problem with caching of ImageFile objects (mainly icons in the Zope management interface) in the 2.2.4 beta is also fixed (and verified using the Cacheability Engine (http://www.web-caching.com/cacheability.html) For more information on what is new in this release, see the CHANGES.txt and HISTORY.txt files for the release: - http://www.zope.org/Products/Zope/2.2.4/CHANGES.txt - http://www.zope.org/Products/Zope/2.2.4/HISTORY.txt Note that we have also posted "diff" updates as .tgz files that will let you easily upgrade an existing 2.2.x site. These updates are available for those currently using the 2.2.x source release or the 2.2.x binary releases. To apply a differential update to your site: - download the appropriate .tgz file from zope.org - shutdown your Zope process - copy the .tgz to your Zope directory and extract it - run w_pcgi or wo_pcgi *if you are not using a binary release* - restart your process Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Help!!
by Ot Ratsaphong 29 Nov '00

Hi, I'm new to Zope and have just installed Zope on a Win98 PC. I'm trying to install squishdot and TinyTable, but Zope tells me that superuser has no permission to install the above products. I have created another user called 'admin' with Manager priviledges but I don't know how to logout of superuser and login as 'admin'. I have tried shutting down Zope and closed off internet explorer and restarting again but I still get into superuser. If I need to login as a non superuser, how do I do this? I have looked for all relevant documentation but can't find anything on this. Your help would be appreciated. TIA Ot Ratsaphong Canberra, Australia

Re: [Zope] [BUG] [Zserver] GET and HEAD give different MIME types

If the implication here is that the corresponding GET request could have meaningful side effects (i.e. not just changes to caches, logs or hit counters), then strictly it would be breaking the semantics of GET, which is meant to be idempotent - capable of being called multiple times without meaningfully changing the state of the server-side system or application. Requests that can change the state are supposed to use POST. Hamish Lawson

First stop postgres and then ... /usr/local/pgsql/bin/pg_ctl -o "-i -d 3" -D /var/lib/pgsql/data start (YMMV with the path etc...) This logs everything to the console. You can vary the debugging level, 3 is a bit "vocal", try 2. cheers, oliver

Yes, this works fine on the Mac. I suspect the difference is because on the Mac they are taking the http content types to figure out the content, but on Windows they are being lazy and using the file extension. Why they didn't use the same code I don't know. To make Dreamweaver on Windows happy, we name our index files "index.html" and then have a DTML method for index_html which is just <dtml-var index.html>. Most of our content people use Dreamweaver (on Macintosh and Windows) to edit Zope sites and are very happy with it.

I assume, because preferences of Python, Zope's implementation language, have had a higher priority than Windows preferences ;-) Python does not like periods in names. > * Should I install 2.2.2. now, or are there any WebDav-updates in 2.2.4? I do not think, the two version will differ in WebDAV support (though someone is working on locking through WebDAV). However, if I would start a new project, I would go for 2.2.4 (I expect less bugs than 2.2.2). > * Is it possible to backup all files from Zope easily?

I > would like to have all the files backed up on a regular filesystem, rather > than a proprietary database. You can do that. But you will lose information. Objects in Zope not only have content, but properties, security attributes, ownership, modification times .... All these will not be extractable by WebDAV. I would go for the backup of the complete proprietary database. At least as the primary backup. As an additional safety belt, I might think about backing up the content independently. Dieter

strange behaviour of ZSQL methods
by Martin Winkler 29 Nov '00

29 Nov '00

Hi listies, something strange is happening with my ZSQL methods. I have a huge query that works great when testing it in the management-interface - it returns about 10 records or so. but when I implement it into a dtml-method getting the parameters via X-Y-GMX: $flush REQUEST as usual, I am getting the whole database in return. I'm quite sure that it's my own fault, so I'd like to see the translated SQL-query in the dtml-method to check for the wrong fields. Is there a tag for it like: <dtml-var MyZSQLQuery showRenderedSQLsource> ? This problem drives me nuts since already two days :-(( Martin
