webdav interface
by nwingfield＠che-llp.com 29 Jan '04

Is Zope's webdav interface documented anywhere, such that I could find the necessary methods that I must write to webdav-enable a custom class? The situation is such that my product will define a single Zope class. An application will use only one instance of this class, which will pull the strings of a relational database and a file system, rather than objects in the ZODB. The relational data dynamically defines the navigational structure of the documents stored on disk. Thus, the webdav behaviors that my class automatically inherits will not work for me, BUT I assume that if I override Zope's default webdav methods I can provide similar functionality. I essentially need to know the webdav interface, i.e. what methods Zope calls to list folder contents, retrieve a file, lock a file, etc, etc. I would be grateful even if someone would just point me to the particular file(s) where this code is implemented in Zope...

Zope Web Serving Options?
by Sean Kelley 29 Jan '04

29 Jan '04

I have a zope 2.6.1 server running on windows 2000 and using the zope www server to run an intranet. I want to host out a public site with nearly the same software (zope,plone,etc) on windows. I need to decide what the best approach is. Do I use something like VHM and run Zope www server or should I install Apache 2 on Windows 2000? Any ideas on pros and cons of each? Performance is an issue so I would guess apache could be good for images,etc. Any other ideas on using the Zope server for a medium to low traffic public site? What about security of running public and private sites on same box?

Re: [Zope] non-persistent publishable objects

The object cannot be completely generic - at the least, it needs an index_html or __str__ method to publish, and it has to satisfy security before it can be traversed to. Parsed XML does this, with a persistent head object, a persistent single XML object, and transient wrapped node objects that are created on the fly, and published with full ZMI access. -- Karl Anderson kra(a)monkey.org http://monkey.org/~kra/

recover from POSKeyError after corruption by pack()ing bug
by Dominik Schäfer 28 Jan '04

28 Jan '04

Hi! I have a serious problem: I think about a week ago my database was damaged by this nasty pack()ing bug. Unfortunately this error was not noticeable until my zope restart yesterday. :-( The consequence is a POSKeyError (POSKeyError: 0000000000000009) which prevents zope from starting. I tried to repair the database with fsrecover.py (from zope-2.6.3 and zope-2.6.4rc1), and it deleted some invalid transactions but it did not solve the problem. Then I tried the instructions on http://www.zopelabs.com/cookbook/1054240694, but had no success at all because I got again a POSKeyError. *g* I used fsrefs.py on the Data.fs and the first 2 error it found was: --- cut here --- oid 0x4 AccessControl.User.UserFolder last updated: 2004-01-16 14:08:02.781121, tid=0x3526BB00BDDB9CCL refers to invalid object: oid 0x9 missing: 'Persistence.PersistentMapping' oid 0xf17 AccessControl.User.UserFolder last updated: 2004-01-16 14:08:14.036884, tid=0x3526BB03BE40544L refers to invalid object: oid 0x1162 missing: 'Persistence.PersistentMapping' --- cut here --- After these 2 errors follow about 24Kb of errors or references to missing objects or objects that could not be loaded. It seems to me, that some very basic objects were destroyed a week ago. Of course all backups during the last week contain the damaged database. :-( It is really a pity, that the consequences of this database damage shows not up until the next zope restart... Is there any possibility to recover the database or to "extract" the transactions of the last 8 days and to prevent the complete loss of data in that time? Has anybody an idea, which I could try? Bye, Dominik P.S. I hope I got the suitable mailing list, I was uncertain if zope.general or zope.zobd fits better...

Revisionmanager Bugs for Win!?
by Sebastian Krollmann 28 Jan '04

28 Jan '04

Hi Phillip, trying to get RevisionManager 1.3.2 running on my Zope2.7/WinXP(ActivePython 2.3.2) I get some problems: 1. the "/tmp/RevisionManager-" + module.filename path cannot be created with os.mkdir(import_dir) on Windows as its a dir/subdir in importModule I think the easiest solution is just make one dir out of the two. The following change works on my machine. (or maybe use os.makedirs()) -- snip #import_dir = "/tmp/RevisionManager-" + module.filename import_dir = os.path.join(INSTANCE_HOME, 'Temp_RevisionManager-%s' % module.filename) #my patch os.mkdir(import_dir) -- snip 2. I got some problems with missing bobobase_modification_time attribute in writeToFS for some object instances: So I did the following quick-hack without a deep look in writeToFS, which worked for me: -- snip obj_last_modified = 0.0 if hasattr(obj, 'bobobase_modification_time'): obj_last_modified = float(obj.bobobase_modification_time().timeTime()) -- snip 3. I get conflicts with the following method in another Product: FileSystemSite.FSPythonScript.FSPythonScript.document_src() in _get_source: if hasattr(obj, 'document_src'): result = mapply(obj.document_src, keyword=kw) I guess its a nameconflict, but I didn't have the time to look to it much closer. The following error message is thrown: Error Type: AttributeError Error Value: _source Error error_tb: Traceback (innermost last): * Module ZPublisher.Publish, line 98, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 39, in call_object * Module Products.RevisionManager.RevisionManager, line 1476, in rm_import * Module Products.RevisionManager.RevisionManager, line 685, in importModule * Module Products.RevisionManager.RevisionManager, line 1190, in writeToFS * Module Products.RevisionManager.RevisionManager, line 246, in _get_source * Module ZPublisher.mapply, line 89, in mapply * Module Products.FileSystemSite.FSPythonScript, line 152, in document_src AttributeError: _source It seems that RevisionManager could help for the cvs-problem of Zope's ZODB objects. So if I could use it in my environment it would be great. Anyway thanks for your effords. Sebastian Krollmann

Something like this, which I use, in a method called 'du', which I just call on various folder objects: <dtml-in "PARENTS[0].objectValues()"> <dtml-var id> <dtml-if title> (<dtml-var title>)</dtml-if> <dtml-try><dtml-var getSize> <dtml-except>no size reported </dtml-try> <br /> </dtml-in> - John Maxwell jmax(a)sfu.ca
