If you're interested in alternate syntax for doctests you might like to
play with Manuel (http://pypi.python.org/pypi/manuel). It's still in
alpha, but lets you design your own test syntax. For example, it would
be easy to have the reST below create a file named "foo.txt" with the
given contents:
.. file: foo.txt
This is my file.
It is very nice.

The last bit of user code in the traceback is attempting to define
ICAttribute, I looked at it, noticed it had three attributes, one of
which was referred to in the traceback ("existence"). The only bit of
user code there was Interval, so I looked at it's definition and noticed
that it didn't inherit from anything or provide any interfaces.
Is there any way in which I might enlighten you further? :)

My current thinking though is to take control of as much of the software as possible so that development == deployment on my local machine to mitigate the risk of breaking things even if it means more disk. 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?

I keep lots of buildouts around (a few dozen), so those advantages add up.

It is, of course, better if you can structure your app so you don't have
to pull the request "out of thin air", but if you do, I'd be a little

Re: [Zope3-Users] ZODB? PostgreSQL?
Hermann Himmelbauer wrote: I'm no expert, but I don't see how transactions would lead to a huge database. I suspect he is referring to the way FileStorage use an append-only file format (between packs). If you never pack the database, it will grow forever. The simple answer is "don't do that". :) This can be an issue if you have a very, very high number of writes of large objects. The DB may grow too fast between packs to be usable. That doesn't normally happen though. When it comes to differences between ZODB and RDBs, I'd say the following: - In many situations you already have an existing RDB, so the decision has already been made. True enough. As you mention below, in this situation you can also use the ZODB alongside a relation DB. - RDBs scale scale very well, so in case your application gets really huge, an RDB is an option. With Zope, you can easily cluster the application server, however the ZODB can not be distributed. (Maybe ZODB can even not make good use of multiple processor due to Python's GIL). They may well exist, but I have yet to see a storage server that was CPU bound (that wasn't running on antique hardware). IO is much more important on a storage server (ZODB or RDB). - In case of data models, which heavily rely on references (=relations), I think you are also better off with RDBs. Why's that? - RDBs have several addons, such as backup strategies, report generation etc. etc. True, although I've never gotten much value out of "generic" RDB utilities, especially report generators. If speed and the data model is not an issue, then I'd opt for ZODB. If speed is an issue, one rule overrides all: benchmark and then decide. Moreover there's also the possibility of a hybrid approach, where parts of the data are stored in the ZODB and other parts in a relational database. That's my preferred general approach. If data is "painfully rectangular", then a RDB might be the best approach. -- Benji York Senior Software Engineer Zope Corporation ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

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).

Philipp von Weitershausen wrote: Jeff Rush wrote: Any suggestions? With the popularity of psycopg + Zope3, any chance we could get psycopgda added into the Zope3 distribution to mitigate this chasing? I don't think that can happen. We're thinking about making the core smaller, not bigger :). Also, not everyone has or needs psycopg, so the testing would become a burden. OTOH, if someone is willing to maintain psycopg and run a buildbot slave for it, we could easily add it to our buildbot master so that every time a change was made to the core the psycopg tests would be run and the maintainer would be alerted to any failures. I suspect this pattern will be more common in the "smaller core/more add-ons" future. PS: It's interesting to note that the Python project is doing something similar now (http://www.python.org/dev/buildbot/community/), and when we get Zope 3 on Python 2.5 I intend to set up a slave to test Z3 every time a checkin is made to Python. -- Benji York Senior Software Engineer Zope Corporation ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

If "zc" were to become "zope community", I'd be *totally* for it (but I don't speak for ZC here, so that may not be cool with others, like say Jim). We'd either keep using "zc" under the new meaning, or switch to something else. BTW, I am not aggravated about the mail; I am just very tired of those pointless namespace discussions. I'm sorry.

[Zope3-Users] z3c vs. the zorg
Stephan's ZSCP proposal suggests using the package name "z3c" for "community" packages. IOW, packages that aren't part of a larger collection like lovely.*, zc.*, etc.. There are currently several z3c packages in existence. The zope3.org packages currently use the package name "zorg". I personally (and at least a couple other people feel the same way) like zorg better than z3c. I'd like to propose that zorg become the name space package for otherwise homeless modules/packages. (In fairness, I'll note that Stephan likes z3c better, and that name is already in semi-wide-spread use). -- Benji York Senior Software Engineer Zope Corporation ___ Zope3-users mailing list Zope3-users@zope.org http://mail.zope.org/mailman/listinfo/zope3-users

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.
