PersistentMapping not persistent?
by alex＠quad.com.ar 07 Nov '01

hey there, I've been trying to get around a problem in my zope 2.4.2 persistentMapping. I've built the zodb auth source of exIserFolder.. it basically uses a PersistentMapping to store all the user accounts, passwords and roles. Everything works fine, but then I noticed passwords getting reset when zope restarts (or just on a long non-activity period) I create a user, set his password and roles.. everything goes ok.. I change his password to something different.. and it works.. but then I restart zope, and his password gets resetted to the old one. now if I use a self.data={} instead of self.data=PersistentMapping() and then add a self._p_changed=1 on every method that updates the self.data everything works as expected, so here goes the question: is PersistentMapping fscked up on 2.4.2 or does it still need something similar to self._p_changed=1 to commit all the transactions back into zodb ? any hints, I could fix this by NOT using PersistentMapping, but since that's what User.py uses, I thought it was going to be a good way to do it.... please.. help :P Alex

IMAP/SMTP web interfaces for Zope
by Dragos Lipan 07 Nov '01

07 Nov '01

I intend to desing an web interface for my server IMAP/SMTP services. I use qmail-1.03, Courier IMAP on RH 7.2. Also Zope 2.4.2. Found two recommended products (even more than email interfaces, but real PIMs), a. worldpilot-release-1.1.0alpha4 b. zopegum-1.2.0-beta2 released also (in another product) as zopegud-1.0.0-preview5. Trying to install lastest version of those products, I failed, Zope don't see them in the list of intsalled products. (exception, from the whole bundle of ZopeGUD, ThreadSafeCounter was the only avaible and working). worldpilot, an older version, worldpilot.1.0.4 seems to work with zope-2.4.2, but after logging into IMAP server, sends me back to login screen (altought IMAP server reports me as logged in). I read about a patch for worldpilot1.0.4 to work with Courier IMAP, but coudn't find any help on their forum. I tried out IMAPAdapter, but either, cannot be intalled as Zope 2.4.2 product :(( Can any body help? even recommend me another product. Thanks, Dragos Lipan Piatra Craiului National Park str.

Zope hiccuping
by Chris Kratz 07 Nov '01

07 Nov '01

We have been noticing that periodically, we get an error from IE that says "Cannot find server or DNS error". It is not easily reproducable (except by just clicking links on the server) and a F5 refresh in the browser [almost] always loads the page correctly. I turned on logging today with the -M startup option and observed the following entries when it happened: B 145697132 2001-11-07T17:15:38 GET /OutcomeTracker/Dev_News I 145697132 2001-11-07T17:15:38 0 A 145697132 2001-11-07T17:15:39 200 32155 E 145697132 2001-11-07T17:15:39 B 145934020 2001-11-07T17:15:40 GET /OutcomeTracker/PeopleOrganizations/index_html I 145934020 2001-11-07T17:15:40 0 B 135053764 2001-11-07T17:15:56 POST /OutcomeTracker/Activities/index_html I 135053764 2001-11-07T17:15:56 2831 B 146464388 2001-11-07T17:15:57 GET /OutcomeTracker/PeopleOrganizations/index_html I 146464388 2001-11-07T17:15:57 0 A 146464388 2001-11-07T17:16:03 200 31200 E 146464388 2001-11-07T17:16:03 Notice how the Get /OutcomeTracker/PeopleOrganizations/index_html never gets the A or E lines, but only has a B and I line. The subsequent refresh finished the request. Interestingly, the two incompleted requests are not logged to z2.log. We can see the request before and the request after, but that's it. The other strangeness is that in the postgres log, we see a "pq_recvbuf: unexpected EOF on client connection". This seemed to point to zope threads dying. Since I'm not getting anything in the logs(*see below), I started running tests with one eye on the currently running processes. And sure enough, whenever I got that error at the browser (cannot find server...), *All* of the zope threads (except the main starter thread) die quietly and come back with new PIDs. It really appears like it reruns the entire startup sequence again. With Z_DEBUG_MODE on I can watch it go through the startup sequence again whenever this happens. But, there are no tracebacks. It's just like somebody clicked restart in the middle of a process. The one glimmer of hope is in the stupid log file: 2001-11-07T19:30:23 ERROR(200) zdaemon zdaemon: Wed Nov 7 14:30:23 2001: Aiieee! 1925 exited with error code: 11 ...restarting... Here's the questions, 1. It appears that something is causing those threads to crash (or end), but nothing is getting put in the log file. Is there any way to get the tracebacks I assume are happening or to find out what is going on? 2. Alternatively, is there a way to run zope in single threaded mode? Z_DEBUG_MODE appears to only apply to the main thread because it goes ahead and spawns additional threads. If I use -t 0 I get two processes, but no response from a web browser request. If I use -t 1, I get three processes owned by nobody and the original one by root. 3. Any further ideas on how to debug this thing? Where do I find what error code 11 is? Thanks for you time and help, -Chris ------------------------------ Chris Kratz chris.kratz(a)vistashare.com

Is anyone pulling excel charts into zope? I'm *trying* to use com and zope on NT to export a chart into a gif and drop it onto the file system with an external method. From there I can use LocalFS or figure out a way to get it into the zodb for display. Thanks - Scott

If I do <dtml-if expr="my_attribute == 1"> <dtml-in> </dtml-in> </dtml-if> my_attribute isn't an attribute of each sequence_item If I do <dtml-in> <dtml-if> </dtml-if> </dtml-in> I cannot use the dtml-in modifiers, like start="1", size="10">...
