Why do you want to recode into DTML? I think that is piece of good code and much faster than DTML. You could try following replacing (original line of your code, follows with DTML code), but not tested: > rec = context.test_select_sql() <dtml-call "REQUEST.set(rec , test_select_sql())"> > print "Fields definitions" Fields definitions > recordset = rec.dictionaries() <dtml-let "recordset = rec.dictionaries()" > rownum = 1 <dtml-call "REQUEST.set(rownum,1)" > for record in recordset: <dtml-in recordset> > print "Row %d" % (rownum), "check", record Row <dtml-var rownum>, check <drml-var sequence-item><br> > rownum = rownum + 1 <dtml-call "REQUEST.set(rownum,rownum+1)" </dtml-in> and so on on the rest of code. > for key in record.keys(): > print key, "=", record[key] > print "-" * 80 > return printed

read-only-database

Hello list, I want to run the database in read-only mode from CD and configured it accordingly in the zope.conf: read-only-database on enable-product-installation off zserver-read-only-mode on Starting Zope, I get the following error: Traceback (most recent call last): File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 56, in ? run() File "\Programme\Zope\lib\python\Zope2\Startup\run.py", line 21, in run starter.prepare() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 98, in pre pare self.startZope() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 257, in st artZope Zope2.startup() File "E:\Programme\Zope\lib\python\Zope2\Startup\__init__.py", line 47, in sta rtup starter.setConfiguration(cfg) File "D:\Programme\Zope\lib\python\Zope2\App\startup.py", line 56, in startup File "D:\Programme\Zope\lib\python\DBTab\DBTab.py", line 96, in getDatabase File "D:\Programme\Zope\lib\python\DBTab\DBTab.py", line 113, in _createDataba se File "E:\Programme\Zope\lib\python\Zope2\Startup\datatypes.py", line 163, in o pen DB = self.createDB() File "E:\Programme\Zope\lib\python\Zope2\Startup\datatypes.py", line 160, in c reateDB return ZODBDatabase.open(self) File "D:\Programme\Zope\lib\python\ZODB\config.py", line 97, in open File "D:\Programme\Zope\lib\python\ZODB\config.py", line 133, in open File "D:\Programme\Zope\lib\python\ZODB\FileStorage\FileStorage.py", line 112, in __init__ File "D:\Programme\Zope\lib\python\ZODB\lock_file.py", line 57, in __init__ IOError: [Errno 13] Permission denied: '\\Zope-Instance/var/Data.fs.lock' r+ means opening the file for updating. This has not to do anything with read-only. Does anybody know what I have to configure additionaly, that read-only works? I run Zope 2.8.4 on windows. Many thanks in advance, Ulla.

Yup, that and Squid 3's "not production quality" status makes the whole Squid/ESI thing a total non-starter, which is a shame... ...but I do wish, as a result, that people would stop touting it as a way to scale Zope apps. cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Problem with WebDAV and non-ascii titles
by Pawel Lewicki 01 Apr '08

01 Apr '08

Hi, I have a problem with accessing files with non-ascii titles via Enfold Desktop (WebDAV)- Zope 2.10.4). Traceback (innermost last): Module ZPublisher.Publish, line 119, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 42, in call_object Module webdav.Resource, line 286, in PROPFIND Module webdav.davcmds, line 124, in apply Module OFS.PropertySheets, line 344, in dav__allprop UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 47: ordinal not in range(128) Is it a bug? I solved my problem with extra line: -------------- + result = [r.decode('ascii', 'ignore') for r in result] result='\n'.join(result) return propstat % (self.xml_namespace(), result, '200 OK', '') -------------- Pawel Lewicki

ZSyncer & Zope 2.10
by Craig Chasseur 01 Apr '08

01 Apr '08

Hello All, We've recently completed an upgrade to Zope 2.10.5 on one of our servers and we've begun to encounter problems with ZSyncer. We use ZSyncer to synchronize objects between this server and another running Zope 2.9.8 (both have ZSyncer 0.7.1 installed). When attempting to "put" folders from the 2.10 server to the 2.9 server, the process hangs and nothing is transferred. However, when we attempt to put individual objects, we are successful. Does anyone know what might be the cause of this issue? ZSyncer 0.7.1, which is the latest release, claims that it may not be compatible with Zope 2.9 and up, but we were able to use it successfully before this most recent upgrade to 2.10. If anyone is aware of a fix or a workaround, or simply has an insight into why this breaks for us, I would greatly appreciate the help. Sincerely, Craig Chasseur University of Michigan

zope on google file system
by Tim Nash 31 Mar '08

31 Mar '08

The google summer of code is almost underway and already has a lot of good ideas but I was wondering if any of my fellow zope users would have any interest in the following area: I don't have the skills but I think it would be cool if some student ported Zope to utilize features of the google file system or libferris. Libferris is a virtual file system that mounts just about everything including postgres, xml and OpenOffice docs. If zope ran on the gfs (primarily adding business logic, security and publishing) it would give a boost to the value of any zope based company. Also, I think it would be fun to run map/reduce on my stored objects! A zope that ran on libferris and offered secure publishing of libferris resources would just be cool. If anybody else thinks this would be useful I will jon the gsoc user list, (even though I'm not a student and I'm not experienced enough with zope to be a mentor) and do my best to make this happen.

RE: Managing Zope objects in Subversion
by martin.gfeller＠comit.ch 31 Mar '08

31 Mar '08

Dear all I would like to thank all those who have responded to my query about management of Zope objects in Subversion. After I sent out my message on 2 March, I got completely side-tracked by other business. Please accept my apologies for this late response. I've experimented with FSDump and FileSystemSite, but that's a one-way solution; i.e., I cannot restore the file system back into ZODB. For me, the most promising respone was: > From: Sam Rangaswamy sam(a)zeomega.com > Sent: Sunday, March 02, 2008 5:46 PM > Subject: Re: [Zope] Managing Zope objects in Subversion > Hello Martin > We use subversion extensively to manage our entire product development life cycle. > We have built tools to move source code back and forth between file system and zodb. > I will have it documented and share it with you and publish it.

Then when the gfs becomes a service that can be purchased (surely coming one day) zope is ready to be ported to gfs. Also, google can only offer so much without the ability to utilize business logic and security. They must be looking for an affordable way to offer business logic that can scale and serving secure objects. A bright student can help them explore using zope for this. > > Also, I > > think it would be fun to run map/reduce on my stored objects! > > Dunno what this means either... > Here is a paper on map reduce.
