Sad but true, I was just sitting here thinking about how the FTP access thing might work into the object database (spurred on by Paul's excellent start at a Q&A).
I think you and I need to get out more on weekends :^)
One thing that struck me was how to manage Versioning when someone is FTPing new objects in... either there should be an implicit new Version created, which I prefer really (more below), or a QUOTE SITE command should be used...
I'm not clear on what problem you are trying to solve here. Is it that you view the entire FTP session as one atomic transaction, and nothing should be "live" until they either log out or do some kind of commit?
The reason I prefer an implict new version (perhaps named FTP-YYYYMMDDHHMMSS based on the start time of the session) is because at least with the tools I use most of the time to work with web sites (BBEdit, Emacs, GoLive CyberStudio) there's really no option to send commands ahead of things, so you're stuck with the default behavior.
_If_ I've stated you goal correctly above, I'll confess I think you're on to something. FTP is different than HTTP as it is stateful. You log in, do a bunch of requests, then log out. Thus, it is valid to re-think the transaction model for ftp.
I wouldn't rely too much on the state-full-ness of FTP. Many FTP tools tear-down FTP connections after a period of time and reestablish them as needed. You wouldn't want your application/editing sematics to be dictated by some tool like ange-ftp.
As for choosing between implicit or explicit, how about have it both ways? That is, have a knob in the Zope GUI that lets you set how FTP transactions should work on a folder?
Possibly, although I think that sessions would provide a more direct way to control this. I'm planning to add a feature to sessions that would allow sessions to be turned on by traversing them, rather than with cookies. For example, suppose you have a folder, F, containing a document, D, and a session S. Doing an FTP put to: F/D whould modify the document directly, but doing a put to: F/S/D would make the modification in a session. Actually, (undocumented sigh) Draft objects do this now. In fact, you could use a Draft object disable FTP access except in sessions. Jim -- Jim Fulton mailto:jim@digicool.com Technical Director (540) 371-6909 Python Powered!
