[clo-devel] upgrading: how do you (want to) use cl.net? [detected: very large home directories]
As part of the upgrading process, I'm looking at the disk sizes, memory, etc to set up for new-cl.net. One of the things I found is that 30 or 40 user accounts together occupy the nearly the full size allocated to /home (14gb out of 15gb allocated). Which raises the question: what do people do with their /home dirs and is /home really the best way to do that (or the best place to store it)? At the same time, I'm wondering if you have possibly valid use-cases for common-lisp.net which you might have tried in the past, but did not succeed at, because cl.net wasn't sufficiently set up. As I'm now determining dimensions, it'd be a good time to take requests into account. Bye, Erik.
Hello. Here are the ideas about cl.net I have now. Maybe it's reasonable to store git/hg repositories at external services as github and bitbucket, and free the common-lisp.net admin resources? Another idea is that it might be good to have a place where Common Lisp demo code might be run. The same way as we have public_html now, user might be able to have for example public_lisp_app where you can place demo version of your lisp application. This is just an idea for discussion, I am not sure it's really necessary to do. I am not sure, how strict sandboxing would be required for lisp code deployed by common-lisp.net users. Should it be run in a single hunchentoot instance shared by all the apps, or maybe a separate lisp processes on behalf of corresponding linux user, or something else. Providing the lisp "hosting" is more difficult probably than other things already p rovided by common-lisp.net, but ability to run lisp code will really be unique service at the moment (in contrast to the source code repos). On the other hand, if someone wants to host a free application, he might put some efforts into finishing ABCL support form Google App Engine, and host his application there.

While I like hosting projects on sites like gitorious or github, cl.net seems like it could be "the place" for CL code. There are benefits both ways; and with git, its fairly easy to have mirrors. I've heard a lot of good things about gitolite. Some people are using it at work, and I am setting it up on another server this week. https://github.com/sitaramc/gitolite Later, Daniel

I think I bumped into a couple of these. People were hosting entire projects out of their home directory, apparently because they had trouble setting up a project. Automated project creation and management would help. On the new features list, somewhere we need to set up a public build farm, where people can get easy access to a variety of lisp implementations and platforms... - Daniel P.S. Perhaps the most active project on the site, Slime, relies on CVS last I checked...

Ok. That's probably not too practical indeed. I've contacted some of the biggest users. Cleaning out some of the old cruft from their home directories made /home go down to a usage of 60%. With that percentage, I know our scaling doesn't need adapting. I'm considering how to deal with the situation for the future. On one hand I think installing a quota of 200MB on the /home directory of each user separately sounds sane and not too restrictive. Otoh, maybe with some monitoring, we can resolve the situation in a less strict way: after all, there's the request at sign-up to use the resources of cl.net sparingly (and exclusively at the service of Common Lisp and its community).

While I think this is a great idea, I'm not sure cl.net is the place for that. The combined services running on the machine are claiming quite a bit of processing power and these build farms can really impact the responsiveness of other services. I don't think we want that for our other services.

Ok. Well, then I guess we'll have to keep running anonymous CVS access through cvsd (pserver). Bye, Erik.

I know a main reason for my excessive usage was that I forgot that I had left some experimental tarballs and such around. They were supposed to be temporary for someone to try them out for me. I just plain forgot about them, so an email reminder would have let me know. Ray

In all honesty: I was one too :-) I didn't even know my /home had grown that big, so, I guess you have a point. Automating such a mail shouldn't be too difficult either. Let's go with that solution and see where we end up. Regards, Erik.
