I am doing this in conjunction with stripping the deployment server to it's barest bones and bringing as much of the software into the buildout as possible. I really would like to see a two stage buildout that does the python construction with a python.cfg and then the main buildout with buildout.cfg file as part of the standard fare. I'm trying a few things today to see if a simple event class and callback can be used to create the python first and have the callback's handler run the main buildout as an experiment. Where you draw the boundary line between the environment and the application has a big impact on how you make these types of decisions. You want to find the optimum place to draw that line so you end up getting the most benefit from the least amount of work (it's kind of analogous to the max-flow min-cut theorem from graph theory). Let me use an example to illustrate. Say you decided to build Python with your buildout. After all, your app uses Python, so to have good reproducibility you want to make sure Python is perfectly clean and built repeatably so you don't get any surprises. Makes sense. Your app is enjoying increased success and one day you need to add some new servers to your cluster. You buy a few new machines, put your OS on them, and build your app. You then run your tests and they fail. Darn. You investigate and find that your Python was built without support for zip compression because the zlib development libraries aren't included in your base OS install. Now you have a decision to make, do you add zlib to your buildout, or do you add the zlib development package to your OS? If Python is part of the environment you add the zlib development package to your OS. Of course that means you need a good way of controlling what is in the OS (environment). Conveniently, there are ways to do that (RPM, APT, ports, etc.). At this point if you draw the app/environment boundary to include Python in your app, you should add zlib to your buildout, right? What happens if you hit a bug in GCC when compiling Python? Do you include GCC in your buildout to make sure you get the right version?

Derek Richardson wrote:
I believe that that will not guarantee a *universally* unique id, but

The RFC prescribes a specific algorithm for generating universally
unique IDs.
Of course, they are only universally unique in a probabilistic way.
It wouldn't be difficult to salt the integer IDs such that they generate
UUIDs that are as likely as any other to be unique. Something like this
would work:
import uuid
int_id = 42
salt = 0x32352352353243263235235235324326
print uuid.UUID('%X' % (int_id ^ salt))
Another option would be to create an IOBtree to map each object's intid
to a randomly generated UUID (generated by the uuid.uuid1 method from
the earlier referenced module).

Instead of maintaining a fork of docutils, Zope 3 should (and may already, I haven't been keeping up with this issue) include tests to make sure we're using docutils appropriately. Best of both worlds: we have continued assurance we don't regress, and we don't have to maintain a fork/patches. -- Benji York Senior Software Engineer Zope Corporation ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users
Re: [Zope3-Users] Security alert: use of Through-the-Web reStructuredText
David Pratt wrote: What about the idea of maintaining a text file in the distribution specific to possible security issues. Is this worth considering for historical purposes so they do not get lost over time or implicitly understood by only a handful of people. Exactly. Any package that needs security-related things verified should have a test (doctest in a text file) describing the problem and verifying that it has been fixed. I don't think we want a single file to hold them though, tests (including these) should normally live near the package that they test. -- Benji York Senior Software Engineer Zope Corporation ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

Yeah, I think zc should continue to mean Zope Corporation.

I'm not sure what you mean by non-foundation code. Isn't the intent to move the entire repository to the foundation? It's all, in that scenario, foundation code. No, I'm talking about people who have developed something and can't, won't, or just haven't signed a contributer agreement, but want to make the code open source and available. Instead of each and every one coming up with their own name space there could be a default, non-foundation name space for them to use. Jim (Washington)'s code is just such an example. In this specific case I'd prefer he put it in svn.zope.org, and if so should be in the zf name space. If, for some reason, he doesn't then the name space could be z (or some other nice name). I'd suggest that code that won't be transferred to the foundation doesn't belong in the svn.zope.org repository at all.

When I got to Zwiki installation example, it looks like the Subversion repository has been reorganized. I found Zwiki, but haven't been able to check it out on my Red Hat 9 system which has a rather old version of Subversion (0.17). Any recommendations on how to proceed? Should I install an older version of Zope 3, or read the book without trying to reproduce the examples? I don't know if going through the Zwiki code will help you or not, but your problem checking it out is almost certainly your ancient Subversion (released over 3 years ago).

On the rare occasions when I have wanted to do that, I just make whatever I want to step through into a single doctest line, like so: a = 1 b = 2 c = a + b Becomes if 1: ... import pdb;pdb.set_trace() ... a = 1 ... b = 2 ... c = a + b Ugly, but it works.

If you test internals of a class in a doctest, the doctest body gets pretty cluttered, which tends to defeat the documentation-esque-ness of them. Are you talking about doctests in docstrings? If so, I definitely see downsides to that use case. I was talking about doctests in stand-alone text files. That's my (and several others) preferred way of using them.
