I don't know about Samba, but Jim Fulton warns against _accessing_ Data.fs over NFS. It is a surefire way of corrupting it. About sharing the Data.fs between multiple Zope processes: Don't do it, it doesn't work. The Data.fs file is locked by the Zope process using it for a reason. For load balancing like this yuo will have to go with either ZEO, or some form of XML-RPC based load balancing (ie. write your own). -- Martijn Pieters, Software Engineer | Digital Creations http://www.digicool.com | Creators of Zope http://www.zope.org | mailto:mj@digicool.com ICQ: 4532236 | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 -------------------------------------------

Hey WorldPilot authors, you have a bug
by Tom Neff 19 Feb '00

19 Feb '00

I am posting this to Zope Digest since the N & H people have no Bug Collector of their own on the WorldPilot site, and I don't know how to get through to them otherwise. If you know anybody who works for them, please pass this on. There is a bug in WorldPilot 1.0 release 1 that causes a re.split error if you have certain kinds of IMAP folder names, e.g. an all numeric one like "2000". The problem is that in WorldPilot.py around line 415 you have 414 for folder in FS: 415 FolderFullName=folder[2] 416 cf=rf 417 Folders=re.split(r'\.', FolderFullName) but apparently folder[2] may not be a string if the IMAP name looked un-stringlike. The following change fixes the problem and lets you work with any IMAP folder name: 415 FolderFullName=str(folder[2]) I really like the looks of WorldPilot - all it lacks to be a really killer app is a search function.

AUTHENTICATED_USER in ZSQL
by Ulrich Wisser 19 Feb '00

19 Feb '00

Hello, I tried to use the AUTHENTICATED_USER object in a ZSQL method. Like: INSERT INTO MYTABLE(USER) VALUES('<dtml-var "AUTHENTICATED_USER.getName()" sql_quote>') But Zope tells me that AUTHENTICATD_USER is not known. Why that?

[ZGotW] ZGotW#4 -- addendum: ReportLab announcment
by Tres Seaver 19 Feb '00

19 Feb '00

*clipped from comp.lang.python. TS* ReportLab, Inc. (http://www.reportlab.com/) is a new company formed on January 21st to develop a new generation of reporting tools for the web and print. The team includes Andy Robinson (CEO and Chief Architect), Aaron Watters (Chief Technical Officer), Robin Becker (Quantitaive Analyst) and Gordon McMillan (Technical Consultant). ReportLab has seed capital and its first customer, and is opening offices in New Jersey and London. The core product is the ReportLab PDF library (formerly known as "pdfgen"). This can be used for - dynamic PDF reporting in real time on the Web - back office forms generation and database reports - adding a cross-platform 'Print Preview' capability to applications - electronic publishing In addition to this, the company has strong general expertise in all aspects of Python development, and will be working on data acquisition and transformation tools, and platform independent graphics solutions. Unlike other PDF generation libraries, ReportLab is intended to go beyond the 'Canvas' level to handle page layout with flowing text and frames, and XML-to-PDF conversion. ReportLab is, and will remain, 100% Open Source. It runs now, but we are seeking intensive feedback on the page layout API over the next few weeks from as wide a developer base as possible before 'freezing' the API. And of course there are many, many more features to add. The company is planning to generate revenue from consulting, service, support and training. There are two main forks to the plan: - an Open Source strategy aimed at making ReportLab a pervasive standard - developing an integrated commercial "Enterprise Reporting Engine" for portals and financial institutions To this end we will be working with 2-3 strategic customers over the next six months. The support arrangements are as follows: 1. The ReportLab library (formerly known as pdfgen) is available from http://www.reportlab.com/ 2. The latest development code is under CVS at http://reportlab.sourceforge.net 3. The mailing list for all discussion is reportlab-users(a)egroups.com. Go to http://www.egroups.com/group/reportlab-users to sign up.

Please send me the contents of /var/spool/worldpilot/storage/<user>/Events so that we can find out what and how it happens, since I haven't had this problem yet. The quick solution to the problem is to remove the /var/spool/worldpilot/storage/<user>/Events folder, shut down Zope, restart and relog onto WorldPilot. The Events folder and contents will be recreated (empty). I assume this helps, at least I haven't received negative feedback yet. Does everybody run into this problem on initial setup?
