I was thinking about the zope command line tools such as zopectl or so. But in fact yes, seems to work, so I'll do it that way :) Thanks -- Kereoz http://www.kereoz.org

I guess it has something to do with the Zeo disk cache. Anyway, the default installation has 'main' and 'temporary', and you can flush the cache for these. I'd like to do it in command line, but I can't figure out if there is a way to do it. I'm also looking for something to choose the objects to cache a bit more precisely (like a list of objects not to cache or so). Regards, -- Kereoz http://www.kereoz.org

Context in a view doesn't see marker interface
by Eric Steele 24 Jun '08

24 Jun '08

For a project I'm working on, I need to include the (Plone) content object that a view is called on in the view template, so if I call mysite/someObject/@@myview, I'll see the someObject page rendered with some extra bits, mostly through overridden (or additional) viewlets defined solely for the interface provided by my view. If I include something along the lines of <tal:block tal:replace="structure context" /> in my view template, someObject renders in the browser. The problem is that none of what's in there appears to recognize the interface that my view provides. Do I need to do some sort of context wrapping? (I also had some success creating a page template on the fly, injecting the current content object's template code into it along with whatever else I wanted to display, but that just feels icky and runs afoul of the restriction against python:test calls in views when calling it on folders and events).

help debugging a "can't pickle" error deep within a catalog reindex
by Rob Miller 24 Jun '08

24 Jun '08

hi, i'm trying to perform a ZCatalog.refreshCatalog() on a catalog with over 29,000 indexed objects. it churns for a good long time, and eventually fails with a long set of tracebacks, of which i've included a sample at the end of this message. i think i understand the gist of the issue... it's trying to write an object (probably a CatalogBrain) to the database, but this object's __dict__ contains a value that is of type instancemethod, which isn't allowed for persistent objects. the problem is that i can't figure out which specific objects are causing the problem. i've used pdb.post_mortem to get a debug prompt way down in the traceback, but the code goes in and out of C modules, so i'm missing a lot of what's happening. and when i interactively peek at the objects that are being indexed when the error happens, there doesn't seem to be anything wrong, and i can index the objects w/ no problem. i've even tried dropping the subtransaction threshold down to 1, so it will try to commit a savepoint after every object, but none of the objects being indexed seemed to have any problems. i CAN verify that the instancemethod that is causing the problem renders like this: <bound method SessionDataManager.getSessionData of <SessionDataManager at /session_data_manager>> even that hasn't proven enough for me to concretely identify the source of the problem, though. i've been working on this for a full day already, and am not sure how to proceed. does anyone have any debugging tips that might help me figure out what, exactly, is causing the reindex attempts to blow up? thanks! -r Traceback (most recent call last): File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/Products/ZCatalog/ZCatalog.py", line 296, in refreshCatalog self.catalog_object(obj, p, pghandler=pghandler) File "/home/rob/topp/14000/builds/20080611/opencore/zope/Products/CMFPlone/CatalogTool.py", line 367, in catalog_object self._increment_counter() File "/home/rob/topp/14000/builds/20080611/opencore/zope/Products/CMFPlone/CatalogTool.py", line 395, in _increment_counter self._counter.change(1) File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/BTrees/Length.py", line 55, in change self.value += delta File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZODB/Connection.py", line 890, in register self._register(obj) File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZODB/Connection.py", line 900, in _register self.transaction_manager.get().join(self) File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/transaction/_transaction.py", line 273, in join self._prior_operation_failed() # doesn't return File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/transaction/_transaction.py", line 267, in _prior_operation_failed raise TransactionFailedError("An operation previously failed, " TransactionFailedError: An operation previously failed, with traceback: File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZServer/PubCore/ZServerPublisher.py", line 25, in __init__ response=b) File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZPublisher/Publish.py", line 401, in publish_module environ, debug, request, response) File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZPublisher/Publish.py", line 202, in publish_module_standard response = publish(request, module_name, after_list, debug=debug) File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZPublisher/Publish.py", line 119, in publish request, bind=1) File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZPublisher/mapply.py", line 88, in mapply if debug is not None: return debug(object,args,context) File "/home/rob/topp/14000/builds/20080611/opencore/lib/zope/lib/python/ZPublisher/Publish.py", line 42, in call_object result=apply(object,args) # Type s<cr> to step into published object.

question about cataloging Page Templates
by Erik Myllymaki 24 Jun '08

24 Jun '08

In Page Templates that use macros, how would you ensure that the entire rendered page is cataloged and returned by a search? For instance, this template: <metal:block use-macro="here/template1/macros/main"> <metal:slot fill-slot="additional-content"> tomatoes </metal:slot> </metal:block> is returned when you search for "tomatoes" but is not returned when you search on a word that is in the "main" macro in "template1" Page Template.

Retrieve Zope data
by Charith Paranaliyanage 24 Jun '08

24 Jun '08

Hi, Can someone help me on this, I need to import objects and interfaces in Zope to another program. Say I have created some objects in Zope and then I need to retrieve them from other application running separately but within the same machine. How can I do this? Let me know if such applications and resources if available. I am using Python language and I am a novice to Zope. So I don't have understanding about which protocols to be used. Regards, Charith

Cache
by Kereoz 23 Jun '08

23 Jun '08

Hi, I use Zope 2.8 and I edit files via ssh. I would like to disable the FS cache for some folders only (where I edit the files) so I don't have it to flush it after each modification. Alternatively, would it be possible to flush the FS cache in command line (rather than via ZMI) and only for a given folder ? Cheers -- Kereoz
