[python script] problem with AUTHENTICATED_USER
by BonviciniJ＠keops.net 21 Apr '05

21 Apr '05

I have problem with my python script. I want to check if a user has a the "manager" role, and add an option in a menu in this case Here is my script: for el in rep.objectValues('Folder'): if el.id=="Administration" and AUTHENTICATED_USER.has_role(self, ["Manager"]): #add option to the menu but Zope displays me an error: Error Type: NameError Error Value: global name 'AUTHENTICATED_USER' is not defined I don't know what is the problem. I use sessionUserFolder (a Zope products), so I think it could be the reason of the problem. Thank you for your help

repozo over nfs?
by Sascha Ottolski 21 Apr '05

21 Apr '05

Hi, I'm wondering how and how often people run repozo. Myself am running it to perform one full backup every night (after a pack), and a incremental one every hour (which needs about 15 min. with nice -n19). What bothers me, however, is the fact, that the backup process is real hit on the overall performance (espacially . The server in question has a RAID-5 setup, storing the backups on the same array as it reads the Data.fs from. Obviously, this keeps the harddisk quite busy during the backup. Now, did anyone try to let repozo write the backups onto a nfs share on another machine? Would that reduce the hit? Besides that, how often do you guys run your backups? In fact, I never needed to recover one until now, but if the case ever happens, I would prefer to have as recent data as possible, of course. Thanks, Sascha

Organisational vs. Functional hierarchies
by David Given 21 Apr '05

21 Apr '05

I apologise if this is a newbie question, but I can't seem to find anything in the documentation about this. The way Zope seems to want to organise things is so that folders roughly equate to classes. That is, if I have B inside A, then B inherits its behaviour from A. All of B's siblings are the same sort of object. However, this means that I have to seperate all my various types of object by kind, regardless of whether they're related. Let's say I have a site that talks about flowers. I have two main kinds of object: images of flowers, which support methods for scaling etc, and descriptions of flowers, which support methods for rendering in various interesting ways. I have to arrange things like this: / Text HistoryOfTheDaisy MoreInformationAboutDaisies HowToGeneticallyEngineerRoses MyFavouriteRoseStories Images WildDaisy DomesticatedDaisy MutatedDaisyFromBeyondTimeAndSpace FakePictureOfABlackRose This works, but is a bit icky. I have my daisies mixed in with my roses. It would be far more convenient for organisational purposes if I arranged things like this: / Daisy Text HistoryOfTheDaisy MoreInformationAboutDaisies Images WildDaisy DomesticatedDaisy MutatedDaisyFromBeyondTimeAndSpace Rose Text HowToGeneticallyEngineerRoses MyFavouriteRoseStories Images MutatedDaisyFromBeyondTimeAndSpace FakePictureOfABlackRose But to make this work, I need to duplicate all the code in each 'Text' and 'Images' folder... Is it possible to tell Zope that methods for a particular kind of object should be found at a particular location, regardless of the containment hierarchy? That way I could have /lib/text and /lib/image that contain the reference code to make my text and images work; the Text and Images folders would then point at these. Or even better, I'd like to do without the Text and Images folders completely and just mix .pt and .jpg files in the Daisy and Rose folders. But I can't seem to find out whether I can do this. Is this in fact possible, or do I need to start tinkering with custom products? -- +- David Given --McQ-+ "Every planet is weird.

Zope via WebDAV
by Erik Myllymaki 20 Apr '05

20 Apr '05

I am trying to use Zope with Dreamweaver via WebDAV. There are lots of good docs and plenty of info in the archives and I have one install setup and working really well. The one that works is Zope 2.7.4 on Win32. An older, production install I want to configure the same way is Zope 2.6.2 on a RedHat 9.0 machine, but it is not working. The trouble I am having with that one is that it downloads all ZPT files without their TAL and METAL tags, and then when uploading, it overwrites the good ones. "Munges" them, as I think I've seen it typed before. Is this just due to some changes between versions, or platforms, or...? I have tried connecting via WebDrive, directly to the zserver WebDAV port and via Apache proxy with the same results. Thanks for any info you can provide.

Zope2.7.4 with Python2.4?
by Luis N 20 Apr '05

20 Apr '05

Hi, I fired up zope on a new server yesterday. It's very very slow! I didn't think about it much at first (because I didn't think it possible), but, > sh bin/runzope /usr/local/lib/python2.4/whrandom.py:38: DeprecationWarning: the whrandom module is deprecated; please use the random module DeprecationWarning) <trimmed> line 99, in ? import psycopg ImportError: No module named psycopg </trimmed> > /usr/local/bin/python2.3 Python 2.3.4 (#2, Jan 1 2005, 23:02:40) [GCC 2.95.4 20020320 [FreeBSD]] on freebsd4 Type "help", "copyright", "credits" or "license" for more information. >>> import psycopg >>> Zope appears to be defaulting, and running with Python2.4 Forgive my newbieness, but might this be because I did something silly like: > python mkzopeinstance.py rather than, > /usr/local/bin/python2.3 mkzopeinstance.py when the instance was first created?

I have another problem (not in relation with AUTHENTICATED_USER): I would like to know if a special function exists to transform special char in html (like HTMLentities in PHP or escape in javascript)

Tips in memory leaks esp with Catalogs?
by Dylan Jay 20 Apr '05

20 Apr '05

Hi Everyone, I have an application that gains a large memory footprint very quickly, in casual testing 100M in an hour or so. I have a largeish ZCatalog with extra PathIndexes, using Plone, Archetypes and various other custom code. Using LeakFinder I get lots of BTree stuff from ZCatalog queries. It looks like it's being created legitimately but what's keeping the references to them and how to go about finding out? In the java world I would use a memory profiler to follow the reference chain till it went where it shouldn't. Is there such a thing for python? If not how does one go about working out whats keeping the memory?
