I'm hoping that we can use (some future evolution of) zdaemon/{zdaemon,zdctl}.py in the Zope 2.7 trunk.

Most of the code for the ctl app that's checked in to the chrism-install-branch is in lib/python/Controller/ZctlLib.py. A stub which imports this code is written out to the bin/zctl.py file in an instance home (after you run configure; make; make instance, for example). The pedigree of this code is that it was originally coded up by Tres but it has been hacked by me since then to support Windows and to support the loading of configuration data from a config file with matching command-line parameters (mostly so you can inspect the config file based environment and pass in --switches that match the names of keys in the config file). It's not a particularly pretty piece of code and I wouldn't mind at all seeing it replaced. * better support for Windows services I'd like to hear more about this; my zdaemon.py currently doesn't do Windows at all. Where can I peek at your code? A file named ntservice.py is written to the bin directory of an instance home after make instance. To install an NT service based on an instance, you would call bin/ntservice.py install. There's not much more to control when it comes to NT services. They don't seem to require any of the coding that POSIX stuff does to switch effective users or run in the background, etc. I'm not sure that you can tell an NT service to restart a process that has died, but probably. This feature is not wired up to any installer or anything, but it should be. * RPM-building support. * where possible, the banishment of environment variables as configuration. All of these things save for the last are more or less complete on the chrism-install-branch of the Zope trunk. The major missing piece is the fleshing out of the interaction between the configuration system (ZConfig) and Zope itself. It works currently but it needs to be improved and canonized to everyone's liking. Can you point to where Zope's use of ZConfig is? chrism-install-branch in lib/python/zope.py and lib/python/Controller/Main.py. You can sorta see it in action if you create an instance home using the instructions that come with the branch and mess around with the config file in etc/zope.conf (put bad keys and sections in there, misspell things, etc, it should give you a pretty informative message about where in the config you screwed up). The sample config file is a little misleading (actually... parts of it are just plain wrong) as it details an older generation of config file ideas. I have not had time to regenerate the default config file. The best place to get an idea of what values are available is the schema for the Zope config in lib/python/Controller/directives.xml. Since ZConfig will also used by other ZC software (ZEO, ZRS), there's a bit of back and forth that needs to be done to get everybody to agree on a way to do it. Once that is worked out, and the proposal is cleaned up, I think we can just merge. 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). It's really no problem, I realize how difficult it is to reverse engineer somebody else's head. Hopefully I can improve the proposal soon and the vision might get clearer to other folks but me. I suppose I should add better logging support to this list of features as well, but since we've already got it going on the trunk and we're already figuring it out, I won't. - C ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

I gather from reading other posts that this is a different format than Zope 3's ZCML. Would it be worth it to at least make some sort of 'ZCML Lite' to do this sort of configuration? The main thing I'm concerned about is that there's a whole new Zope coming down the road that depends heavily on configuration files, and it might make sense to start weaning people onto its general syntax if Zope 2's finally going to have a config file. As other folks mentioned, we made a conscious decision to not have an XML config file format. That said, the schema (the allowable values and sections) of the config file may be in XML and might even use ZCML (if I can figure it out). I have been paying attention to RDM's checkins to the metameta stuff on the Zope 3 branch, but I still haven't quite figured out how to use ZCML for this purpose. I've got a homebrew solution that does use XML now. Anyways - good work. The better support for Windows services alone would get you a beer if I happened to be on that coast.. :) Thanks! Cheapskate. I think you owe me at least two other beers anyway. ;-) - C ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

From a sysadmin's point of view, they're already conditioned to doing this to install open source software, so under the Pinball Machine Principle, when they see one in Zope, they'll run that first before reading (the whole) README file.

Please don't merge anything until people have had a chance to see what's going on and gotten the plan finalized. Per the plan above, I'd like for there to be a (relatively short) period for people to volunteer and add proposals to the plan, followed by a process of prioritizing and coming to closure on what will / won't be included.
