It's not really so much that I think that environment variables are evil or anything, it's just that I think there should be one and only place to find and set most configuration data for Zope. Currently you configure Zope via a combination of z2.py switches and envvars. There are currently 40 Zope environment variables and 22 z2.py switches. There is no definitive reason for any one of these settings becoming a switch over an envvar or vice-vera (it was at the whim of the particular developer who decided to add the config requirement), so it appears (and is) rather haphazard. Some things like 'Z_DEBUG_MODE" and the -D switch actually even do the same thing, and it's hard to tell which you're supposed to use and which is supposed to "win" in these cases. Additionally, some things aren't really configurable at all (you're stuck with file or syslog logging, no way to send to an NT event service, etc). We'd like to fix this kind of thing and provide a more consistent front-end to configuring Zope settings. Additionally, since lots of Zope configuration data wants to be hierarchical (loggers, zodb databases, severs), and since environment variables and switches don't lend themselves particularly well to being hierarchical, a hierarchical config file format is nice. I hope this makes sense as a defense of using a config file. I don't particularly like config files either, but I think once a piece of software reaches a critical mass, they become a necessary evil. In my opinion, Zope reached that mass about three years ago. ;-) > a) Code spent garnering values is minimal, I don't have to worry about >acres of code spent parsing yet another config file format or the >inevitable quirks and bugs in that code. It doesn't get much simpler >than os.environ.get() Yup. We've got a seriously complicated piece of software to deal with config files now, and it's only getting more complicated.

I feel that it's just as simple (or maybe simpler) to look in a config file. The Zope config file will be stored on the filesystem (not in the ZODB), and it's in a format much like an Apache config file, so no ZMI or custom client stuff will be necessary. There will be tools provided to parse the config file if necessary. > c) Environment variables lend themselves to nicely to modification by >third party tools; I can set environment variables in shell >scripts, python scripts, whatever--the paradigm is language >agnostic.

They shouldn't be. Lots of applications use environment variables as "superglobals" (e.g. $HOME, $PYTHONPATH, etc.), and this should be the kind of thing that Zope should use them for as well. I can see, for example, setting the SOFTWARE_HOME using an environment variable or throwing some debug switch using an envvar. But stuff like "ZSESSION_TIMEOUT_LIMIT" and "ZOPE_DTML_REQUEST_AUTOQUOTE" and the mishmash of logging parameters (STUPID_LOG_FILE, ZSYSLOG, ZSYSLOG_ACCESS, etc) are just begging to be put into some sort of configuration file. So far, we've done a bunch of work to come up with a config file format, some parsing software, and some configuration schema software. We're hoping that with a little work, we can make the configuration of Zope through a config file not suck *too* badly. If you have ideas about what should (and should not) be done wrt canonizing a config file for Zope, please detail specifics here as nothing is set in stone.

I'd like to compare notes on this. Where's the control script that
you are using? I'm hoping that we can use (some future evolution of)
zdaemon/{zdaemon,zdctl}.py in the Zope 2.7 trunk. This separates the
concerns of
- the actual server process (Zope/ZEO/ZRS; for ZEO, this is
runsvr.py)
- a daemon subprocess manager, which restarts the subprocess when it
dies, etc. (zdaemon.py)
- a tool to control the subprocess manager, telling it to
start/restart/stop the server subprocess, etc. (zdctl.py)

Apologies in advance: my refrain seems to be "where's your code for
X?" -- there's so much good stuff in your branch that I don't know
where to begin, especially not with the Zope part (in ZODB, I know my
way around better).

Hi Could we get the Install and Configuration proposal cleaned up, with so many comments it's not clear what the actual proposal proposes to deliver now. Also parts of it's problem statement are just plain wrong. I currently have many (read every version of Zope including Alpha's and Betas since 2.4.1b1) installed on the same box, and I have 18 instances of which at least 8 are running concurrently on our dev box, currently using at least 2 different versions of Zope (2.5.1 and 2.6.0). (Some of the non running instances if I started them up would be on 2.4.3 etc.. Currently we can do everything listed as a problem in the proposal, it is clean, neat and everything is in it's place.

[Zope-dev] Writing the second Zope Community Handbook
Hello everyone, first of all, sorry for the cross-post, but I need to reach about everyone possibile in the Zope Community. While talking with Maik Roeder this weekend, we noticed that there might be a huge urge to write another community-authored Zope Handbook. So I called Nadja Rosmann, chief editor of Linux Enterprise magazine, today and talked to her. She was very excited about it and showed great interest. The first book we (the Zope community) wrote with them was a great success and started at Linux Enterprise an entire series of pocket books. The first book, which is also known as the Yellow Book, was a set of articles by various community members about Zope. The book was published in German and an English version was available online. The book covered a wide variety of subjects and offered a great alternative for people that were not willing to spend the money for a complete book, since the price was only 12.50 Euros. The book was therefore perfect for giving it to clients and other interested people without making a big investment. So, we plan to write a book like that again! This time however, we will publish the book on paper in at least German and English. I also talked to Nadja about a French version, since France seems to have some really cool Zope development going on. I truely believe that this book will help Paul's goal of having Zope grow 10x. BTW, since we will have many authors, I propose to donate the payments to a common Zope-oriented project, such as the creation of a Zope-booth or something else (the last donations went to the EuroZope e.V. for organizing conferences). Of course every author will receive a free copy in a preferred language. The next thing I need to discuss would be the topic of the book. Nadja and I agreed that it might be a better marketing argument, if we try to concentrate on Zope's Content Management capabilities. This way, many companies should be interested in writing about their products and case studies. What do you think? Now to the organization of the project. We need about 20-24 articles most having a length around 12k-20k characters (4-6 A4 pages) and some central articles having 20k-30k characters (about 10 A4 pages). This would produce a book with around 300 pages, which would be sold for 20.00 Euros. Since this is a community effort, people need to volunteer writing articles/chapters. Therefore, please E-mail me privately (so we do not cause huge cross-post threads), if you would like to write an article and what you would like to write the article about. Once I have enough responses, I will publish the list. Here are some points that might help thinking about a subject: - Do you or your company have developed your own Content Management System in Zope? Then tell us about it. Examples: CMF, Plone, Silva, Kontentor ... - Do you or your company have a client that you want the world to tell about? Why are you not writing a Case Study? Examples: Universities, Government agancies, other companies... - Do you have a product you developed (or extensively used) for Zope that you think should receive more attention or could be useful to many people? Right, write about it! Examples: Wikis, RDB Adapters, ZEO, I18n tools, Discussion Boards... - Do you know a particular thing about Zope that you particularly liked about Zope and that caused you using it? Please, tell us about it. Examples: RDB/LDAP Integration, User management, speed of development (RAD) ... - Are you developing some cool stuff for the Zope core? Write about it... - There is also some interest in having a couple reports on the progress of Zope 3, so if you are a Zope 3 developer, you might write an article comparing the differences between the Zope 2 and Zope 3 way of doing things. Examples: RDB Integration, Caching, I18n, Components versus Multi-talented objects... - If you do not know a topic, but still would like to write an article, contact me anyway and we will find a subject together. Also, we do not need only writers, but also translators. So, if people do not feel comfortable writing an entire article, they could also volunteer as translator. Now to the time frame. I think that it will be best to write the articles during Christmas, since it is a slow time and people have some more time on their hands. My ambitious goal is to send the complete set of scripts to Nadja by January 25th (Why that day? Because it is her and my birthday. ;-). This project cannot happen without the community! Please help us making this project a success!

This issue is most probably resolved somewhere in between, but I can
not find any trace of this at [EMAIL PROTECTED] nor [EMAIL PROTECTED], thus I
drop in my 2 cents here.
I did just now run into a similar problem, and may offer the following
explanation after some debugging:
It seems the 'allow_module', etc, gets not executed by Zope in advance,
except if this is the __init__.py of a 'Product', or this module is
imported by some core module or product. This is quite standard python
behaviour; the module is not initialized before import, and Zope does
some extra work to initialize all products on startup.
If one tries to import the code from a python script, the security
machinery first check, if the module has some security info, and imports
it afterwards, if the info is found. But as the module is not imported
anyway, it is not initialized, and has not such info and thus will not
be allowed for import.
It seems there is some chicken and egg problem here, or I have missed
something completely.
The workaround is to insert a dummy 'import stripogram' in some
product, which triggers the security info creation -- or make the little
helper scripts a product of its own.

This works, as Your test code imports something via file system (no
access restriction) from module "stripogram" first and then creates the
test script, which finds the module info on import as the module is
intialized yet.

In this case the module has not been initialized yet, and the TTW
access is the first import, which failes due to the security
restrictions problem mentioned above.
Hope this helps; and hope someone can point me out I am wrong on the
chicken and egg problem of 'non-Product' module import.
Cheers,
Clemens

[Zope-dev] Re: [Zope] Cache Parameters
This is also something that improved greatly in 2.6. Doing this in 2.5 means hacking the source (hmmm, I think I lost that patch), and alot of meditation on the debugging output. You will still need a deep understanding of the pickle cache (the thing that was rewritten in 2.6) to asses the impact of any changes you might make.
