Creating Graphs
by Stuart Foster 19 Aug '00

19 Aug '00

We need the ability to create multiple graphs from data that we get from Postgres. Currently we use a py method to call gnu plot, but we are looking for an alternative to serve up graphs. Any suggestions? I took a look at the Python Image Library is this the best solution? TIA Stuart

Declaration of a sheet property as a personnalise class...
by Vincent 18 Aug '00

18 Aug '00

Hi, I would like to add a new property to a ZClass that I created. Right now, I can choose between int, date, text, selection..., How can I choose another ZClass I created in the same product ? Thanks Vincent

After further investigation, there was another aspect to the problem that was not addressed in the recent hotfix. I've uploaded a new hotfix release (Hotfix_2000-08-17) that supercedes the one from the 9th and includes the extra fix required. http://www.zope.org/Products/Zope/Hotfix_2000-08-17/ If you run a Zope site and allow untrusted users to edit DTML on your site, you should install this updated hotfix. There is no need to uninstall the prior hotfix release. These fixes will also be in the 2.2.1 release, expected next week.

But you don't seem to be able to EDIT the title of the property sheet ever again. Is there some magic property sheet property name or is there just no way to edit the title from the management interface?

Both succeeded eventually in getting Xron started, but we didn't succeed in diagnosing the problem, nor in determining precisely how to work around it. I myself haven't been able to reproduce the problem. The problem seems to occur only on Linux, but it does not always occur. Some users have successfully started Xron on Linux with no problem. The problem seems to have to do with contention for a lock on ZODB. Did you see any log or console message that would confirm this? One user went to the console and killed all the Zope processes that were running at the time, then restarted Zope from the command line. The second time, Zope started up correctly with Xron. Another user thought that he had mistakenly tried to start Zope while logged in as root. When he restarted as a different user, Zope started up with Xron correctly. I suspect that the user was not relevant to the Xron problem (it is normal in some installations to start as root), but that the restarting was the key. One user thought that the monitor process contributed to the lock contention. I don't know, but it might be worthwhile to try to restart Zope without the monitor (changing the start-up options to disable the monitor). The problem seems to relate to Xron's creating the Schedule catalog the first time the Xron product is loaded during Zope start-up. If you succeed in creating the Schedule one time, the problem will not recurr, as Xron will just use the existing Schedule. I hope that helps you get started. Let me know how it goes. I'll copy this email to the zope list in hopes that someone else can shed some light on the problem. -- Loren ----- Original Message ----- From: "Nicholas Lo" <nicklo(a)siliconcreation.com> To: <lstaffor(a)dynalogic.com> Sent: August 18, 2000 12:41 AM Subject: xcron test > Hi Loren, > > I have a problem with installing Xron 0.9 onto my machine.

The problem is: I have a Zope 2.1.6 with SiteAccess and Apache 1.3.12 with the mod_proxy and mod_expire set up to that all request get at por 80 by Apache are proxed back to port 8080 of Zope. SiteAccess garantees that this cycle works all the time and port 8080 is never accessed directly. This works fine. The problem is that the Apache proxy is not caching the pages as it should, so that requests made to Zope once are not made again until expired from the cache. This results that every single request made to Apache goes directly to Zope and than the lack of robustness of ZServer makes it very slow and unstable (as expected). The strange thing is that the directory used for the cache is been filled up with files but it looks like Apache is ignoring them and going directly to Zope. When I shut down Zope, it never goes to the cached files and when I make requests to Apache the Zope´s log grows up all the time for the same bunch of pages. Here´s the configuration in my httpd.conf CacheRoot "D:/Program Files/Apache Group/Apache/proxy" CacheSize 50000 CacheGcInterval 1 CacheMaxExpire 24 CacheLastModifiedFactor 0.1 CacheDefaultExpire 1 CacheForceCompletion 90 ProxyPass /zope/ http://10.10.10.176:8080/ ProxyPassReverse /zope/ http://10.10.10.176:8080/ ExpiresActive On ExpiresDefault A86400 ExpiresByType image/gif A604800 ExpiresByType image/jpg A604800 ExpiresByType text/html M43200 Anyone knows why this happens? What´s the workaround? I searched through all the web and find nothing about the mod_proxy configuration so it´s turning to be extremelly difficult to maintain the Zope site, even with the robust Apache as the front-end.

You could use Xron to schedule sending the email. You could schedule it for later or for "now". Either way the email would be sent asyncronously from the original request.

If Zope is going to increase its market then this sort of book is essential to make Zope accessible. Can I help at all? But a book covering the internals will be useful.

A *major* change between 2.1.x and 2.2.x is in the security dept. 2.2.x runs all methods using the security level of the _owner_ of the method, regardless of whether this is a lower or higher level than the currently authenticated user. My guess is that your method has no owner (which is what pre-2.2.x objects default to when run under 2.2.x). This means it is running as anonymous which does not have rights to do what you want. Specify an owner for the method that has sufficient rights to do what you want and try it again.

Apache is not caching Zope pages
by Fabio Akita 18 Aug '00

18 Aug '00

Hello again There´s something very strange with the Apache + ZServer solution presented in the zope.org howtos. The problem is: I have a Zope 2.1.6 with SiteAccess and Apache 1.3.12 with the mod_proxy and mod_expire set up to that all request get at por 80 by Apache are proxed back to port 8080 of Zope. SiteAccess garantees that this cycle works all the time and port 8080 is never accessed directly. This works fine. The problem is that the Apache proxy is not caching the pages as it should, so that requests made to Zope once are not made again until expired from the cache. This results that every single request made to Apache goes directly to Zope and than the lack of robustness of ZServer makes it very slow and unstable (as expected). The strange thing is that the directory used for the cache is been filled up with files but it looks like Apache is ignoring them and going directly to Zope. When I shut down Zope, it never goes to the cached files and when I make requests to Apache the Zope´s log grows up all the time for the same bunch of pages. Here´s the configuration in my httpd.conf CacheRoot "D:/Program Files/Apache Group/Apache/proxy" CacheSize 50000 CacheGcInterval 1 CacheMaxExpire 24 CacheLastModifiedFactor 0.1 CacheDefaultExpire 1 CacheForceCompletion 90 ProxyPass /zope/ http://10.10.10.176:8080/ ProxyPassReverse /zope/ http://10.10.10.176:8080/ ExpiresActive On ExpiresDefault A86400 ExpiresByType image/gif A604800 ExpiresByType image/jpg A604800 ExpiresByType text/html M43200 Anyone knows why this happens? What´s the workaround? I searched through all the web and find nothing about the mod_proxy configuration so it´s turning to be extremelly difficult to maintain the Zope site, even with the robust Apache as the front-end. Thanks
