[Plone-users] Zsyncer issue
by Matt Howell 31 Jul '05

31 Jul '05

I have not used Zsyncer before, so please excuse me if this question is remedial. Would Zsyncer be a good solution for making a ZEO-based ZODB highly available? If not, what are other people doing for larger Plone / Zope deployments? -Matt

inspect and page templates in python product
by Peter Bengtsson 31 Jul '05

31 Jul '05

I'm using the inspect module in my python product to step back when doing some debugging. My code looks something like this:: class MyProduct: def hasRole(self, r): for i in range(25): try: print inspect.stack()[i][3], print inspect.stack()[i][2], except IndexError: break It works wonderfully well except when the caller of hasRole() is a Page Template defined with the PageTemplateFile function. (it might be equally bad with a ZODB persistent template I think). Does anybody know if and how if there is a way to step back and found out which template called hasRole() [ and maybe even which line] ? If I do this debugging now, it gives me something like: (hasRole:326, <expression>:1, __call__:47, evaluate:221, do_condition:636, interpret:234, do_defineSlot:694, interpret:234, no_tag:389, do_optTag:394, do_optTag_tal:409, interpret:234, do_useMacro:671, interpret:234, __call__:190, pt_render:96, _exec:106, _exec:343, _bindAndExec:343, __call__:306) -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

Re: [Zope] What "Maximum age of a cache entry (seconds)" means in RAM Cache Manager?

But what > this parameter mean? Would somebody give me an explaination? It means exactly as it seems to mean. Maximum age: No cache entry older than n seconds, where n is the value you supply for that setting, will be used. Cleanup interval: Appx every n seconds, sweep the cache and remove entries that are expired, as in the above parameter. You would not want to do this too often (for performance reasons) nor too little (lest the cache become very large). --jcc -- Building Websites with Plone http://plonebook.packtpub.com/

What "Maximum age of a cache entry (seconds)" means in RAM Cache Manager?
by Litao Wei 30 Jul '05

30 Jul '05

I have read the zope book and zope online help about RAM Cache Manager. But all of them didn't say anything about the parameter "What "Maximum age of a cache entry (seconds)" mean. It looks that this parameter like "Cleanup interval (seconds)", which zope book explained as "The lifetime of cached results.". But what this parameter mean? Would somebody give me an explaination? Thank you.

strange getPhysicalRoot behaviour
by rr＠nederhoed.com 29 Jul '05

29 Jul '05

Good day all, Using Zope 2.7.6 I'm trying to use the getPhysicalRoot() function. In a rather large site we have a folder called 'functions' placed in root. This folder contains a formatting function 'far' I want to use in some other folder. But in the path from root to the place I the function to be called, I have another 'function' folder, with local functionality. When calling 'context.functions.far()', it fails to acquire the far function. Which is explainable. My plan was to call it directly: 'root.functions.far()', but 'root' does not exist in the zope (python) script. if I use root = context.getPhysicalRoot() I am forced to reenter my Zope username and password and will not get permission to call the getPhysicalRoot function. What am I doing wrong? What can I do to make the getPhysicalRoot function available? Friendly greetings, Robert-Reinder Nederhoed The Hague, The Netherlands --

Updating BLOB fields in Interbase database
by Ashley 29 Jul '05

29 Jul '05

I'm not sure if this is the right place for this, if not, my apologies. I've got a Clients table in an interbase db with various fields, one of which is a BLOB field (subtype text), used to maintain some notes. When inserting a Client into the table, this field populates fine. However, when attempting to update the client, for some reason, it won't. It just will not allow me to do an update with the notes field in the statement. I've googled around, and found lots of bits helping with Delphi, and lots of statements that BLOB fields in Interbase are tricky to update, but nothing that helps. Has anyone out there found a way around this? I'm using currently using gvib as my database adaptor, as kinterbase does not seem to want to install at all (seemingly problems with ldap ..). My Zope instance is installed from a Plone installer. Zope Version (Zope 2.6.1 (binary release, python 2.1, win32-x86), python 2.1.3, win32) Python Version 2.1.3 (#35, Apr 8 2002, 17:47:50) [MSC 32 bit (Intel)] System Platform win32 Thanks in advance Ashley
