RE: [Zope-dev] Logging for ZScheduler?
On Thu, 15 Jun 2000, Loren Stafford wrote: It would be a good idea if there was a field in the ZEvent that defined the subsystem used in the zLOG call. I didn't follow your point here. By "subsytem" do you mean which logger in the loggers tuple? Then do you mean that different ZEvents could log to different loggers? Why would this be a "good idea", I mean, do you have a use case in mind? from zLOG.py: def LOG(subsystem, severity, summary, detail='', error=None, reraise=None): The first argument specifies a subsystem, which is passed to the logging implementation. A logging subsystem may choose to ignore log messages from particular subsystems, or perform special actions (eg. if a critical error has occured in the ZScheduler subsystem, page the sysadmin). By allowing an individual ZEvent to override the subsystem reported, you can gain even more control. -- Stuart Bishop Work: [EMAIL PROTECTED] Senior Systems Alchemist Play: [EMAIL PROTECTED] Computer Science, RMIT University ___ 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 )
Re: [Zope] LoginManager HOWTO?

" Well, looks like the GenericUserFolder is more advanced. So I go to its page. In it there are another observation: But do you want advanced? If you just want to store your authentication information, UserDB is just fine - moving to GenericUserFolder in this case may just cause you troubles, as more advanced also means more complicated. UserDB is a simple user adaptor that is all you need if you are storing your usernames, passwords and roles etc. in the one central RDBMS. GenericUserFolder is what you have to move to if you are in a more peculiar environment or want to use Radius authentication. LoginManager supports all the functionality of GenericUserFolder, but is still in developmental stages and probably not recommended for production sites but may be the perfect choice if you don't plan going production right now. I'm looking for a sequence of steps needed to configure and use the LoginManager. How to add users? How to add local roles? How to integrate it whith LDAP (not for now, but in the future)? How to use a RDBMS server, like PostgreSQL, to store the accounts (in case I cannot put LDAP up an running)? Sounds like you would be happiest with UserDB for now and migrating to the LDAP Adaptor in the future. Or if you wait long enough before migrating to LDAP, you will probably find LoginManager supports LDAP out of the box with no coding. I'm not a Python programmer, and I have a limited knowledge of Zope and DTML, and my english is only better than your portuguese...

It would be great if you could do it, but beware that you will be
benchmarking a lot of overhead if you only plan to measure storage
performance. Why not use ZODB directly ?
If I talk HTTP, it measures things fully - Python's interpreter lock
will mean a storage system written in python will benchmark better
without having to compete with ZServer, and vice versa for storage
systems with non-pythonic bits.
I've got a nice NetApp here to run some tests on.
What filesystem does that use ?
No idea :-) Something log based that is very fast and handles huge
directories happily. It also appears that another member of this
list has an EMC Symmetrix box to test on, which I believe is the next (and
highest) level up from a Netapp.
I've attached a prerelease alpha of zouch.py for giggles. Not even a
command line yet, so you will need to edit some code at the bottom.
The current settings generate about 360 directories and about 36000 files,
and proceeds to make about 18 reads. This bloated by test ZODB
to just over 200MB and took about 2.6 hours attacking my development Zope
server from another host on my LAN.
Todo:
tidy and vet ugly code
command line interface
dynamic option (do more intensive DTML stuff - currently just
standard_html_header/standard_html_footer)
catalog option (since DTML Documents arn't catalog aware, will need
to make two calls to make a new document)
upload larger documents and some binaries (200MB isn't great for
benchmarking when you might have a gig of ram doing caching for you)
standard test suite

Note that you need to create roles at a point in the tree, and they then appear and are usable on the management interfaces from that point down. I have to restrict access to resources by student subject or course. I'm currently only using about 60, but its quite possible I'll quickly end up in in the hundreds when more students start using Zope resources. The trick is to only 'create' the role when you need to grant rights to it. A role exists only in the point in the tree it is created and down, and there is nothing to stop you creating the same role in multiple locations. If you create them all in your root folder, your security screens become useless, but it is fine if you only have 5-10 defined at any particular point. -- Stuart Bishop Work: [EMAIL PROTECTED] Senior Systems Alchemist Play: [EMAIL PROTECTED] Computer Science, RMIT University ___ 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 )

The DB might be hit once for each thread, as the ZSQL cache is not shared between Zope threads.

(NO, not a 400k editor with WYSIWYG preview and an exotic scripting engine - it's supposed to be _very_ slim) Please give me feedback on this, because if the community wants such a thing, I might start working on it. I would love one. If you you proceed, it would be nice if the applet allowed pluggable backends. In this way, one applet would exist that would allow the user to select one of a number of different editors to use (which should keep the Brief users, the Emacs users, the Notepad users and the Vi users all happy - provided they can be bothered implementing their own backend). -- ___ // Zen (alias Stuart Bishop) Work: [EMAIL PROTECTED] // E N Senior Systems Alchemist Play: [EMAIL PROTECTED] //__ Computer Science, RMIT WWW: http://www.cs.rmit.edu.au/~zen ___ 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 )
