Remember, his site is an intranet. We at least, have had good results by increasing the internal ZODB caching. I fail to see how squid could help us with a site that is mostly non-static. It would be nicer of course if we could use some other kind of caching, so I am always open to suggestions :-) /dario -- -- ------------------------------------------------------------------- Dario Lopez-Kästen, IT Systems & Services Chalmers University of Tech.

Zope vs Plone: performance issues!
by Hugo Ramos 25 Jan '06

25 Jan '06

Hi all, I'm responsible for a big corporate intranet and corporate portal. They were using Zope/Plone before I got here and the problems are too many. Let's talk about performance issues... Plone is VERY SLOW responding requests. All content is stored in ZODB objects and zcatalog is used to search. But even if you request the intranet home only, it takes about 10 seconds to load. The hardware is very good and lots of ram is used in the servers. They also have zeo + 2 zope instances running in the same machine. I've never seen this in my life... only 3 machines running 2 zope instances + zeo instance, separately. Do you think Zope(logic)+MySQL(content)+Apache(HTTP server) is better solution than Zope+Plone ??? TIA -- Hugo Ramos - ramosh(a)gmail.com Senior Zope consultant

2.8.5/Win32 image opening error
by Mikko Ohtamaa 24 Jan '06

24 Jan '06

Hi, I installed Zope 2.8.5 for Windows (to use with Plone, moving from 2.7.4). I cannot start Zope in debug mode since I get errors about missing images. At least SiteErrorLog and OFSP complains about missing icons, though files are there. Looks like Zope just can't find them. IOError: [Errno 2] No such file or directory: 'images/version.gif' This happens on two machines I have tested. I might be doing something wrong in my setup/installation, but don't know what. Any hints to fix it? -Mikko Stdout: NOTICE global_symbols.py:22:Tue Jan 24 12:55:30 2006: 'Starting C:\\runtime- workspace\\hrm\\Data\\Products\\GroupUserFolder at 4 debug level' 2006-01-24 12:55:30 WARNING Init Class Products.GroupUserFolder.GroupUserFolder.

[ANN] iungoCMS 06.01
by Maik Jablonski 24 Jan '06

24 Jan '06

Hi, if you search an fast-and-flexible-and-easy-to-install-and-maintain Zope-based CMS for the typical "little" website, which is maintained by a little group of people, have a look at iungoCMS... http://www.iungo.org What is iungo? -------------- Based on the web-application-server Zope iungo provides a solid system to build up object-oriented web-databases, easy-to-use-wikis, content-, document- and knowledge-management-systems. iungo targets users and developers, who trust in the "Keep it simple"-philosophy and want to maintain control over their work. iungo tries to connect people with information. Features? --------- - Strict separation of content and application: your content can be moved between different zope-instances and iungo-versions without the fear of breaking anything. - Folderish-Content: In the web all "entities" are links, not folders, documents or files... no more headaches for users what content-type to use... in the default iungo-install there's only one for all...;) - Placeless-Content: All objects have a unique id (autogenerated per default) and can be moved around within the repository without breaking any links between objects. - KISS (Keep it simple stupid): It's easy to develop a custom layout with a basic knowledge of DTML or ZPT. - Expandable: Create new content-types for webdatabases with some clicks in the ZMI. What's new? ----------- - iungo is based on the paradigm of placeless content, so all documents can be moved in the hierarchy without breaking any links between documents. iungo now supports and delivers nice bookable urls for all documents, which was an often requested feature for the default-installation. Cheers, Maik

repozo problem
by Gerhard Schmidt 24 Jan '06

Hi, I have some problems with repozo. I have setup repozo for backup of our Data.fs about two years ago and it worked without problem until 4 weeks ago. Since than it behaves very strange. I am running repozo with den follwing parameters. /usr/local/bin/python /usr/local/www/Zope/bin/repozo.py -v -z -B -f /data/zope/zeo/var/Data.fs -r /data/share/backup/data.fs/ and I get the following error. looking for files between last full backup and 2006-01-23-03-43-40... files needed to recover state as of 2006-01-23-03-43-40: /data/share/backup/data.fs/2006-01-22-03-44-01.fsz Traceback (most recent call last): File "/usr/local/www/Zope/bin/repozo.py", line 501, in ? main() File "/usr/local/www/Zope/bin/repozo.py", line 494, in main do_backup(options) File "/usr/local/www/Zope/bin/repozo.py", line 431, in do_backup reposz, reposum = concat(repofiles) File "/usr/local/www/Zope/bin/repozo.py", line 248, in concat bytesread += dofile(func, ifp) File "/usr/local/www/Zope/bin/repozo.py", line 192, in dofile data = fp.read(todo) File "/usr/local/lib/python2.3/gzip.py", line 224, in read self._read(readsize) File "/usr/local/lib/python2.3/gzip.py", line 289, in _read self._read_eof() File "/usr/local/lib/python2.3/gzip.py", line 308, in _read_eof raise IOError, "CRC check failed" IOError: CRC check failed when I run it without compression the backup works but it doesn't do incremental. reprozo is run by cron ever 2 hours and the Data.fs is packed only once a day.

I have suspected an inconsitency in the Data.fs but i've done a fsrecover twice since the problems started and it came out without errors. The Zope systems and the daily pack are working without Problems. Our Data.fs is 2.6G at the moment (fresh packed) Bye Estartu ---------------------------------------------------------------------------- Gerhard Schmidt | Nick : estartu IRC : Estartu | Fischbachweg 3 | | PGP Public Key 86856 Hiltenfingen | EMail: estartu(a)augusta.de | on request Germany | |

Security issue with manage_page_header
by Stacy.Ladnier＠noaa.gov 24 Jan '06

24 Jan '06

I have patched the Navigation and Management so the drop-down containing 'Set Preferences' and 'Logout' is displayed in the menu frame. The 'Set Preferences' displays a customized page to the user to set a unique set of options for my application. My product consists of several additional roles and relies heavily on a nested structure of folders and acl_users for granting access. Previously, under 2.7 I set default security for every store, which is a top level container, and the entire site consists of several stores. I have now upgraded to 2.8, created each store as a separate mount point so it has its own ZODB, and security is set at the root level. However, now if a 'Custodian' with an account nested inside of a store chooses to go to 'Set Preferences' they recieve an Unauthorized error. Zope complains on the RESPONSE.setHeader() call contained in manage_page_header. I have gone as far as to set __roles__=None on the manage_page_header and preferences page in my Navigation patch. Only those users with an account established at the root can gain access to the preferences. Otherwise, they recieve an error. If I allow Anonymous all permissions in the Security Tab (BiG bad no no in my case) then users below the root level can gain access to the preferences page. In my understanding of Security, I thought declaring __roles__=None would also allow users to access an object without needing to pass security. What could I possibly be missing???? My site, including the bug, is currently public and to be demoed in two days. Any assistance or guidance is greatly appreciated.
