[Zope] Packing data.fs programmatically
I am using the following module to pack my data.fs programmatically before a backup is made. This was largely taken out of the Zopelabs cookbook - thanks! def packZODB(): try: import os, sys os.chdir(/path/to/Zope/python) sys.path+=['/path/to/Zope/python/was/required/to/load/Zope/module'] import Zope Zope.configure(/path/to/zope.conf) app = Zope.app() app.Control_Panel.Database.manage_pack(days=0) get_transaction().commit() app._p_jar.close() return 1 except Exception, inst: for arg in inst.args: print Oh dear! %s % arg -- Now for the wierd bit. I successfully ran the code that went into this module line-by-line in the Python interpreter. The data.fs was beautifully packed. However, when I run this script from the command line (through another script that acts as a hook) the line app = Zope.app() fails with the error No such file or directory. Now I am confused, coz the code lines that you would expect to fail if either of the required paths were not correct ran quite happily. I am running Python 2.3.5 and Zope 2.7. Does anyone have any thoughts?

On 1/30/06, Dieter Maurer [EMAIL PROTECTED] wrote: Peter Bengtsson wrote at 2006-1-30 18:54 +: I've noticed another strange behaviour with the Acquisition module in Zope 2.9 that might give us some clues as to why refreshing doesn't work. Imagine some code that looks like this:: from Acquisition import aq_parent class MyProduct(Folder): def index_html(self): print type(aq_parent) is None return Hello World! The first time I run this, it prints False to stdout because ac_parent is of course a function. BUT, if I refresh the product (no change made to the source) and run this index_html() again it instead prints True because ac_parent has become None. Isn't that odd? Indeed, especially because no type can be None! Oops! A typo. It should be:: def index_html(self): print aq_parent is None return Hello World! It is known that refreshing (more generally reloading a Python module) can cause objects apparently becoming None. This happens because the variables defined in the old module instance are rebound to None when the module is released. This would explain that aq_parent in your index_html would appear as None if you happen to access an object still associated with the old class. However, the type of None is NoneType and not None. As written earlier: refreshing is essentially a Python feature (delete a set of modules from sys.modules, then reimport some of them again) rather than a Zope feature. It should be possible to reproduce your weird observations with Python operations only. I tried but was not yet able to reproduce it (I still use Zope 2.8 (but that should not matter) and Python 2.4.1). I noticed that since zope 2.8, the function manage_performRefresh() hasn't changed. The only difference I can see is that (my) zope 2.8.5 comes with ZODB 3.4.2 and my zope 2.9.0 comes with ZODB 3.6.0. The code is this:: if RefreshFuncs.performFullRefresh(self._p_jar, self.id): from ZODB import Connection Connection.resetCaches() # Clears cache in future connections. message = 'Product refreshed.' There is no code difference in RefreshFuncs.performFullRefresh() between zope 2.8.5 and zope 2.9.0. If someone can guide me I'd like to dig deeper into ZODB.Connection.resetCaches() to see if there's be a big difference in version 3.6 that might have caused my beloved refresh to stop working. -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

The term high traffic site doesn't mean a thing when it comes to threads or the cache (or in general). It's way too general. Determinations about cache sizes or thread numbers can only be made with specific requirements, (estimated) traffic data, hardware specifications and knowledge about the Zope application in hand, period. Less threads and bigger caches only make sense when you are under memory pressure and (hopefully) your pages render fast enough so that less threads can still satisfy the rendering load. jens ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

I am looking for something that covers login in users, building tables out of data stored in zodb, getters and setters for objects in the zodb, collecting a variable in one page and passing it on to another page where it modifies the data display, working with Sessions, etc. I guess what I'm looking for is a template for a real application, not for the individual pieces of functionality. And if it it has associated test framework, unit tests, setup scripts etc. that is even better. One application that has it all factored out to the most common way zope is used would be a beautiful thing. Also, more writting on how you guys go about developing zope apps. Do you start from scratch each time or do you have your own templates? Do you use the zmi? Do you mix zpt and dtml? What is the best products? most commonly used products?

There's only so much that one machine can do. If I understand the Zope framework, the idea is that read-to-write ratio for the ZODB is going to be much greater than one, meaning that there are going to be a lot more reads than writes. In this case, having some load balancing and ZEO client caching will make overall performance faster. However, if you're doing lots of writing to the ZODB, you'll probably need to explore ZEO even more in the area of mounting different ZODBs at different places in your ZEO clients' trees. Like some of the other people said, you probably should just tune it as needed. It's also a Bad Thing to be running your servers at or near capacity; you should leave plenty of headspace for usage spikes. I've certainly run into situations where Zope stuff was processor-bound and slowing everything down, but the RAM wasn't even 25% full. In cases like this, more zserver threads (or more ZEO clients) helps even things out.

This is specious reasoning from a statistical point of view. You never have only two requests. To have a proper statistical evaluation, you need a theoretical model of the distribution of requests over time. This can be as simple as a request every t. Then you have a continuous flow of requests, and the two means become equal. Just try it with 4 units of work and equivalent time distribution as in the original example: - Case 1: (1+2+3+4)/4 = 2.5 - Case 2: (2+2+4+4)/4 = 3 If you generalize to n units of work, you'll get (the math is simple): - Case 1: n(n+1)/2n = n/2+0.5 - Case 2: 4((n/2)(n/2+1)/2)/n = n/2+1 Which are equivalent to n/2 when n grows.

You will never again be able to load this oid without exception (as it was deleted). Okay, so is this a bug in TemporaryStorage? If so, should I just chuck it in the collector? You should look at the code.

[Zope-DB] Re: Ape, postgresql and plone: UnmanagedJar instance and 'exportFile' attribute errors
The same error is thrown if you use APE with filesystem storage. I have Zope 2.7.8, Python 2.3.5, Plone 2.1.1 and Ape 1.0. No idea why this happens. I've had zero luck with APE, and have come to the conclusion that no one really uses it. Bill Jeff Macfarland wrote: Ape 1.0 is set to store in postgresql 7.4.6. Things seem work fine until I go to add a Plone Site in the ZMI.
