Zope fails on large task?
by David Whiteley 20 Jan '06

20 Jan '06

I have a quite complicated data collection and reporting system based on zope2.7 and postgresql. All the postgresql stuff is handled by external scripts. I have used page templates throughout. It is running on a Debian Sarge based system, and uses Apache as a front end. This is my first experience developing with Zope, so I have probably done things oddly, but... I have script that generates a large bundle of data dictionary for each "target entity", which is in this case is a person. I then pass this data to a script that converts it to XML. My template repeats over a list of people, and concatenates and sends the XML for them all to the user, where a bit of XSLT creates a paged report. It works for a few people. If I try too many people it fails with an Error reading from remote server message from the Apache. I cannot find any hints in the apache or zope logs. I have tried to monitor the server to see if any resources are running out, but have not found anything. Can anyone suggest how I try to diagnose this failure. I repeat, I am fairly new to Zope, and so need fairly basic help.

Zope MailTemplates
by Erik Myllymaki 19 Jan '06

I haven't delved too deeply here, but I think Zope MailTemplates are wrapping any subject longer than 70 characters. Is there any way to turn this feature off?

Software to Administer a Zope Project?
by Pablo Ziliani 19 Jan '06

19 Jan '06

Hi everybody, I want to keep track of a project I am developing in Zope, so basically I need some advise on the software I might prefer to adopt. I tried trac, but I find it a bit complicated to have to admin everything through the shell and also, unless there's an easy way to integrate zodb stuff to it, I'm not interested in the svn part, just the project management itself (tickets, milestones, etc). I'm not saying that I won't use Trac, but maybe I'm just missing something. Zepp is not an option. Thanks in advance, Pablo

Re: [Zope] Products have incorrect "home" attribute

In lib/python/App/Product.py line 549: product.home=home 'home' is the product path as determined by OFS.Application.install_product; it looks, from a cursory glance, that this should be reset every time Zope is restart. It should be perfectly safe to delete the Products from your Control Panel Products folder and restart Zope to have them recreated though. If you don't trust this procedure, back up the ZODB, but from my reading this should happen every time you start Zope anyway. -- Martijn Pieters

ANN: ZSyncer 0.7.0 released
by Paul Winkler 18 Jan '06

18 Jan '06

ZSyncer 0.7.0 Released Version 0.7.0-final (2005/12/15) is available for download from sourceforge: http://sourceforge.net/project/showfiles.php?group_id=28073&package_id=2091… ZSyncer is a Zope 2 product that allows you to synchronize and compare objects from one zope (source) to another (destination). It is a lot more convenient than the old manual export / transfer / import procedure. Noteworthy changes since 0.6.2: Features added: * We now have two-directional sync! Instead of just "sync", we now have both "put" (like the old sync) and "get" (pulls changes from the remote system to the client system). Thanks Alan Milligan! * new method of ZSyncer and ZSyncerTool: callManyRemote() to call multiple arbitrary methods on the remote system and return a list of results. * Pretty complete example skins for ZSyncerTool integration with CMF/Plone. See README.txt for more instructions. Doesn't have all features yet (e.g. no "pull" support). * Should work with Zope 2.8 now! * The "override user" stuff is removed from the UI. You now have to use the proto://user:passwd@server url format. See README.txt for more information. * The (broken) XMLRPC code has been removed. * New config variable, "upload_threshold_kbytes", determines the point at which the server spools data to a temp file instead of RAM. * "delete" now deletes from both local and remote systems. * SSL connections using ConnectionMgr should now set timeout properly. * Lots of unit tests! For bugfixes and older changes, see CHANGES.txt. -- Paul Winkler http://www.slinkp.com

Isn't package_home() doing the same? package_home serves a different use-case, I think; you use it within a Product to determine paths to templates and such. As for users of Product.home; QuickInstaller uses it, and the product object itself uses it to find the README.txt file for the ZMI tab. -- Martijn Pieters

Zope 2.7 with postgresql 8.1 anyone?
by David 18 Jan '06

18 Jan '06

Is anyone using successfully Zope 2.7 with postgresql 8.1? Or any other version of Zope? What is your database adapter product? We're using Pyscopg (happily using 1.1x with Zope 2.7 and pg 7.3/4), but have problems getting it to work with either Psycopg 1.2x (protocol missmatch errors) or Psycopg 2.x (transactions are getting aborted for no reason). We're happy to dabble, but would like to know that it is working in principle. We're on a delivery schedule and don't want to be dependant on bug fixes still required. Thanks!

Autoconnect with ZMySQLDA 2.0.9
by Dennis Allison 18 Jan '06

18 Jan '06

I have been seeing occasional "release unlocked lock" errors from a storage error in a two-phase commit which really comes from a "Lost connection to MySQL server during query". Apparently this arises from a failure of self.db.ping() to find a connected database as the transaction is opened. It is possible that the connection has really timed out. Looking at the code it appears that ZMySQLDA does not attempt to recreate the connection. Is that correct? What's the recommend approach to re-establish the connection? -d --
