proxies
by Chris Withers 16 Jan '08

16 Jan '08

Hi All, I saw the zope.proxies module and wondered if it might be able to help me with two problems I need to solve: - can these proxies be used to keep track of a traversal path in much the same way (although no seperate containment and context chains needed) as the old Zope 2 acquisition wrappers did? - once a proxy has been created, the the object it's proxying for be replaced? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

KeyError in ZRDB.DA cache handling
by J Cameron Cooper 15 Jan '08

15 Jan '08

On our fairly busy site (http://cnx.org) we're seeing in the logs some instances of an error in Shared.DC.ZRDB.DA:: ... Module None, line 97, in search_form_handler - <FSPythonScript at /plone/search_form_handler used for /plone/content> - Line 97 Module Products.RhaptosRepository.Repository, line 537, in searchRepository Module Products.RhaptosRepository.VersionFolder, line 456, in search Module Products.RhaptosModuleStorage.ZSQLFile, line 44, in __call__ Module Shared.DC.ZRDB.DA, line 492, in __call__ - <ExtZSQLMethod at /plone/portal_moduledb/20071212233625.240206723892> Module Shared.DC.ZRDB.DA, line 393, in _cached_result KeyError: ("\nSELECT p.*\nFROM persons p\nwhere\n p.firstname ~* req('href='::text)\n or\n p.surname ~* req('href='::text)\n or\n p.fullname ~* req('href='::text)\n or \n p.personid ~* ('^'||req('href='::text)||'$')\n or\n p.email ~* (req('href='::text)||'.*@')\n\n", 0, 'devrep') This is trying to remove a key from the ZSQL cache to shrink it down to size, but doesn't find the key. From Shared.DC.ZRDB.DA._cached_result: # if the cache is too big, we purge entries from it if len(cache) >= max_cache: keys=tcache.keys() # We also hoover out any stale entries, as we're # already doing cache minimisation. # 'keys' is ordered, so we purge the oldest results # until the cache is small enough and there are no # stale entries in it while keys and (len(keys) >= max_cache or keys[0] < t): key=keys[0] q=tcache[key] del tcache[key] del cache[q] # <===== line 393, with the error del keys[0] It looks a lot like: https://bugs.launchpad.net/zope2/+bug/143805 but we have that fix in our Zope 2.9.8: http://osdir.com/ml/web.zope.all-cvs/2006-11/msg00150.html Perhaps it is another high-load leak? I don't think it can be multiple threads doing cleanup at the same time, unless maybe there's a transaction commit in there somewhere I don't know about. Or maybe I'm running into the problem described in the big comment at the end?:: # When a ZSQL method is handled by one ZPublisher thread twice in # less time than it takes for time.time() to return a different # value, the SQL generated is different, then this code will leak # an entry in 'cache' for each time the ZSQL method generates # different SQL until time.time() returns a different value. # # On Linux, you would need an extremely fast machine under extremely # high load, making this extremely unlikely. On Windows, this is a # little more likely, but still unlikely to be a problem. # # If it does become a problem, the values of the tcache mapping # need to be turned into sets of cache keys rather than a single # cache key. Would it be unsafe to toss a try/except around the del cache[q] bit on the theory that it's already deleted, so, hey, why fail? It'd be really nice to keep this off of users, even with it if does cause a bit of a leak. I'll probably be setting up some logging to try and characterize this further, but anybody have any clues? --jcc -- Connexions http://cnx.org "Building Websites with Plone" http://plonebook.packtpub.com

python 2.5 and zope components?
by Chris Withers 15 Jan '08

15 Jan '08

Hi All, Is there a known/unknown list of what Zope 3 components work with Python 2.5 and what don't? My memory tells me a lot of work was done on this recently for a Google SoC project, I hope my memory is right :-) Also, what's the canonical way of compiling Zope 3 components on Windows? Is there a canonical source of compiled Zope 3 components for Windows? cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

3.4 controlled-packages
by Christophe Combelles 14 Jan '08

14 Jan '08

I'm trying to figure out where (in the svn) the following file is: http://download.zope.org/zope3.4/controlled-packages.cfg Isn't it supposed to be the same as the one found in zope.release (trunk or 3.4.0b2 tag) ? Where does the difference come from? Christophe
