If I'm understanding correctly, one need to use the five:registerPackage
ZCML directive and then use ZTC.installPackage. Many collective.*
packages can be used as reference, including collective.formcriteria.
There are probably simper examples, but that's the first that comes to
mind.

It's a very frequently asked question — "how can I get back > to the state my site was in before I started messing with security?" :) I've released it: http://pypi.python.org/pypi/collective.securitycleanup collective.securitycleanup GenericSetup handlers to restore Zope security to defaults WARNING: Backup your ZODB before using this package! The Zope 2 security framework is very powerful and one of it's greatest strengths. A lot of it's power comes from it's flexibility. Exposing that power to site adminsitrators often ends up giving them enough rope to hang themselves with. This is exactly what the "Security" tab in the ZMI does. In many cases, a site admin or consultant is faced with the daunting task of restoring all the security settings throughout the Zope object heirarchy in order to bring sanity and predictability back to the site. The collective.securitycleanup package provides GenericSetup handlers for restoring the role mappings and local roles back to their defaults. This handler can be used in combination with existing handlers to set role mappings and to re-apply workflow security settings to help start the process of security cleanup. The clean up is performed on all ancestors including the Zope application root and by walking down the heirarchy to all descendants. This means all descendents of the context the handler is used on and all ancestors of the context including the root will be cleaned up. It will not clean up siblings or anything else that is not a direct ancestor to the context. The clean up removes all permission settings stored on the instance which effectively restores them to code defaults. The clean up also removes all local roles except the "Owner" role for the user returned by OFS.interfasces.IOwned.getOwnerTuple() if already assigned. Use of this tool will likely only ever be a starting point. So be sure to test thoroughly before deploying to your production server and backup your ZODB before using it.

I'm not completely sure, but I'm *pretty* sure. I remember stepping through the code before and seeing a new transaction start. As for "as it should", it just seems reasonable to me that a functional test fixture would try to use the real application behavior as much as possible.

Why?? > And what does that decorator actually do? If memory serves, a *functional* test fixture calls the Zope publisher when a testbrowser request is made. The publisher opens a new transaction, as it should. So if there are uncommitted changes in the transaction used by the test before submitting the testbrowser request, then those changes won't be reflected in the new transaction opened when the publisher handles the request. I'm guessing that since this is a fairly common situation it was decided that the test case should commit before submitting the request to the Zope publisher. I think it's proper that a *functional* test case opens a new transaction when responding to requests since that's how the application behaves. I also think that it's proper for a widely shared test fixture such as this to gracefully handle the common case where a test writer needs changes made in the test to show up when handling the request as it does now. I *also* agree that your case is the purer one and that should be supported. So I guess I'd advocate for making the commit in the Functional.publish() method configurable. At any rate, to solve your immediate problem, I would just write a new test case class that subclasses whatever test case class you were using, copy the publish method implementation from Functional and just remove the commit line. Then you can use your test case class in your tests and the commit won't be made.

Then it seems like you're not getting at the actual pickle error and thus aren't looking at the object whose __getstate__ returns the offending instance method.

The actual error of your TB is the error that savepoint raises when a previous error has occurred. So changing the subtransaction threshold just changes which object is being indexed when the savepoint *happens* to be run and notices that an error has been raised for a previous object in the savepoint. At least, that's my read of it. >> A next step can also be to put a pdb.set_trace() at >> transaction/_transaction.py:340 in the register() method such that >> it's is only called when the offending object is added to the >> transaction. > > i'll give this a shot, thx. > >> Hope some of that helps, > > even just having someone to discuss it with is helpful, for my sanity > at least... ;-) Well, then I'll have to enjoy your sanity vicariously. :) Ross ___ 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 )

Can you get a pdb.post_mortem prompt at the actual ZODB/serialize.py:416
error or only at transaction/_transaction.py:267 where some sort of
previous error is handled?
If the former, I often find it informative to step up to
ZODB/serialize.py:407 where obj.__getstate__() is called and find out
what obj is. Is it the same object every time? If not, is it of the
same type every time?
A next step can also be to put a pdb.set_trace() at
transaction/_transaction.py:340 in the register() method such that it's
is only called when the offending object is added to the transaction.
Hope some of that helps,
Ross

[Zope] ZPL and GPL: What should one consider when choosing a license?
Recently, someone wrote to me regarding one of my z3c packages which is licensed under the GPL. They asked me to license them under the ZPL saying that the ZPL would allow the widest range of use for those packages. They also implied that using the GPL impacted the licensing of other code that uses mine. Mostly this is just a debate I've never taken up before. I've always just chosen the GPL because it's the most aligned with my values and ideals on a "visceral" level. IOW, it's a gut choice not an educated choice. I realize this is an old debate. I found some lengthy threads on zope-dev from 2001, but I think there have been some license changes since then. I also read the following blog posts: http://radio.weblogs.com/0116506/2005/11/21.html#a370 http://awkly.org/2005/11/21/gpl-considered-harmful/ Unfortunately, the comment by Chris McDonough mentioned in the latter doesn't seem to be accessible any more. I'd love to read it. >From those blog posts, I don't really see any corroboration of the claims of the person who made the request that I switch to the ZPL. What exactly about the GPL narrows the range of developers who can use my code? What about the GPL impacts the license of other code that depends on my code? Here's what I want. I want anyone who modifies or forks my code to make their modifications just as accessible to myself and the community as my code is in the first place. I also want anyone who forks my code to credit me and other contributors as authors of the code they forked. I have a slight preference to allow proprietary code to depend on my code without having to open source their code. I definitely want commercial entities to be allowed to sell products and services that include my code as long as credit is given to the authors. That's just what I want from my admittedly naive perspective. I'd like to hear comments on why others think I should or shouldn't want any of those things from a license. I'd also like to hear how others think the license available relate to what I want from a license. Thoughts? Is there documentation somewhere about choosing a license? Maybe a howto I missed in my googling?

[Zope] ANN: z3c.recipe.egg - Recipes based on zc.recipe.egg for working with source distributions
I just bundled up and released some zc.buildout recipes I've found useful. Attached is the README.txt. http://cheeseshop.python.org/pypi/z3c.recipe.egg Ross == z3c.recipe.egg == Recipes based on zc.recipe.egg for working with source distributions. Editable Distributions -- The z3c.recipe.egg:editable recipe uses the easy_install --editable and --build-directory options to download multiple source distributions. The source distributions will be placed in the part directory and managed by the buildout if build-directory is not specified. If so, the distributions will be replaced when newer versions are available. So be sure to set build-directory to a directory not managed by buildout if you want to maintain changes to the source distributions. The z3c.recipe.egg:editable can be used to assemble a set of subversion checkouts to work with specifying subversion URLs in find-links as is supported by easy_install. See the easy_install documentation for the syntax for using subversion URLs. There are a number of ways in which it is more flexible to control checkouts via recipes rather than svn:externals. Finally, if the develop option is true then the distributions will be installed in develop mode. See z3c/recipe/egg/editable.txt for more details. Running Setup Scripts - The z3c.recipe.egg:setup recipe calls arbitrary setup.py commands on multiple distributions in a buildout. The z3c.recipe.egg:setup recipe can be used, for example, to automate releases. When the source is ready for release, the setup recipe is configured to run the "register sdist bdist_egg upload" setup commands. To ensure release only runs when intended, the setup recipe can be used in it's own release.cfg file that extends the buildout.cfg file. With this setup, releases for multiple projects can be made with "bin/buildout -c release.cfg". The z3c.recipe.egg:setup recipe also supports the develop option as with z3c.recipe.egg:editable.

[Zope] Deploying with buildout (was: buildout, instancemanager, and eggs)
We have a Plone 3.0/Zope 2.10 application that we need to develop on, maintain and deploy to a ZEO server and multiple ZEO clients. Currently we use svn bundles of Zope and Plone and our own packages and products in one big svn:externals definition. We also use some more recent versions of certain products and packages than those included in the upstream svn:externals. For example: Zope svn://svn.zope.org/repos/main/Zope/branches/2.10 Zope/lib/python/zope/app/interface svn://svn.zope.org/repos/main/zope.app.interface/trunk/src/zope/app/interface Though I haven't seen any documentation to this effect, svn seems to treat the second svn:externals as a "svn switch" on "svn up". So one question I have is how would I "override" the versions of some package like this using buildout? Another question I have is that there aren't releases for all the dependencies our application has. I'm wondering what the best way is to define a canonical release for deployment to our cluster. Ideally, we'd have a buildout (or whatever) on a staging server where we're testing the candidate for deployment and then when all tests pass that *exact* source should be deployed to the cluster. How might one do this without upstream releases? Is there a way to get buildout and setuptools to play together so that I can build a source distribution from the test passing buildout on staging? Is there a way I can have a buildout on each cluster node such that a simple ./bin/buildout will get the latest deployment release for that node?

[Zope] OT: PythonLabs Team Moves to Digital Creations!
Now here's something readers of this list might be interested in ... Original Message Subject: PythonLabs Team Moves to Digital Creations Date: Fri, 27 Oct 2000 20:42:42 -0500 From: Guido van Rossum <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] (Python mailing list),[EMAIL PROTECTED], [EMAIL PROTECTED] Newsgroups: comp.lang.python To all Python users and developers: Less than half a year ago, I moved with my team to BeOpen.com, in the hope of finding a new permanent home for Python development. At BeOpen, we've done several good things for Python, such as moving the Python and Jython development process to SourceForge, and the successful release of Python 2.0. Unfortunately, BeOpen.com's original plans for PythonLabs didn't work out as hoped, and we weren't able to reach mutual agreement on workable alternative plans -- despite trying for months. I am proud to have found a new home for my entire team: starting today, Tim Peters, Barry Warsaw, Jeremy Hylton, Fred Drake and myself are working for Digital Creations. We will be spending part of our time on core Python development (including Jython and Mailman) and part of our time on Python infrastructure improvements that also benefit Zope. Python will remain Open Source; Digital Creations has no desire to monetize or brand the Python language or specific Python distributions. All future work we do on Python as Digital Creations employees will be owned by a non-profit organization yet to be created. We think of this new organization as the Python Software Foundation. In the meantime (while the PSF is under construction) I will own such copyrights personally. We're excited to be working for Digital Creations: they are one of the oldest companies active in the Python community, one of the companies most committed to Python, and they have a great product! Plus, we know they have deep financial backing. We trust that Digital Creations will provide a stable home for Python for many years. Digital Creations has also offered to take over hosting of the python.org and starship sites. On behalf of the Python community, we're grateful for this support of the two prime community sites for Python, and we expect to be implementing the transitions shortly. These are exciting times for the PythonLabs team -- and also for Python and its community. Mainstream successes for Python are showing up everywhere, and we're proud to be a part of such a smart and friendly community.

[Zope] Can multiple processes access a ZODB3 file?
If I have Zope running, using ZODB3 on Data.fs, can a separate process also use ZODB3 to access Data.fs? I have my suspicions, but I'm not sure. I'm interested in this because I'm in the middle of a balloting period. People email me their ballots. I will need to check them for validity, send out confirmation or error messages, and eventually tally the results. I definitely want a persistent store, so ZODB seems good. Also, I eventually would like this to be a Zope product, with people able to access the results on the web (and, in the future, vote on the web). But getting it Zoped may be too much work in the short run. So, I'll have a Zope server running on my Debian system, and another process will be going through the mail. It would be more straightforwad if that other process worked directly with the database, rather than going through Zope via http or xml-rpc or something similar. So I'm wondering if that's possible. I can always take the indirect route if, as I suspect, that's necessary. I'm cribbing from parts of the Poll product as appropriate. The polling machinery is considerably more complex though: a restricted list of voters, various muckings around to get the info out of the email, and preference voting (1 for first choice, 2 for second, etc with an instant run off). I know Zeo is more in the multi-process space, but I don't want to use it for this project because I don't have time to learn it; it's alpha; and it seems like overkill for my problem. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
Re: [Zope] RE: Generate edito form from dtmlDocument : property type
Yes, it's definitely a very interesting product and goes a long way toward what I was thinking about. It's a step toward what could be a killer app for zope I think - most web developers would kill for an open source through the web RAD tool. I still think it's worth peeking at what I've done because it generates ZSQL code as well as the DTML skeleton for a typical application. It would be easy to integrate I imagine with metapublisher. In my experience, the ZODB is great for development and testing, but there comes a point with big apps where you think seriously about RDBMS storage.

[Zope] RE: Generate edito form from dtmlDocument : property type
I think the general idea of automating html generation for data entry web forms is a very good one, but IMHO it's heroic to even think about doing this sort of stuff in dtml!! (This discussion probably should be moved to zope-dev?) I've got something which generates useful DTML and ZSQL code automagically from ZClass BASIC propertysheet contents and so can be used to do the grunt work for making zclass add and edit methods. It generates ZSQL code which is only tested for the sybaseda but would be relatively easy to tweak for other DA's It uses a single python external method - have a look at http://www.zope.org/Members/rossl/ZClassExtender for an example of what's possible...feel free to extend it?!!
