[clo-devel] Managing (version controlling) the common-lisp.net main website
by Erik Huelsmann 08 May '11

08 May '11

The clo project contains a copy of the c-l.net website in its repository. This repository is checked out in the public_html directory of the clo project and synced hourly from there to the main web pages in /var/www. However, if I look at the /var/www directory, it contains much more than what's in the clo directory and repository. To resolve this situation, I'd like to copy all files in /var/www to the clo project and add them to the repository. There were ideas from others - I believe Raymond and Stelian - to use a different solution to maintain the website; maybe using a CMS or wiki-based system which allows WYSIWYG editing on the web. For now, I'm going with my "copy back" solution. However, it looks to me like we do need *some* kind of enhanced control. (Maybe even just a description of location of different kinds of files for maintainers to consult?) Bye, Erik.

[clo-devel] cvsroot syncing regularly takes too long
by Erik Huelsmann 08 May '11

08 May '11

Hi, On new-cl-net, the "sync cvsroot" script is regularly exceeding its runtime window (which is 20 minutes). One solution could be to change the nice parameter (-20). I'm hoping that others have better ideas, like changing the script from polling to event-based, which would eliminate the need to check all files individually. Does anybody have some cycles to look into the options? Bye, Erik.

[clo-devel] Security update required for exim4
by Hans Hübner 07 May '11

07 May '11

Drew, it seems that the Debian distribution that is installed on tiger does not supply a very current version of exim4, and today a security hole was reported in the version that we are running. Is it possible to add a package source with up to date security fixes so that we can update exim4? Thanks, Hans

Re: [clo-devel] link to OTRS docs for mail processing
by Hans Hübner 07 May '11

07 May '11

Hi Erik, I have installed the otrs gateway at otrs(a)tiger.common-lisp.net - As otrs runs under a specific user ID and I did not feel like inventing a suid wrapper, I have implemented the gateway by an explicit exim configuration directive (see /etc/exim4/configure if you are interested). I sent a few test mails to that address, but otrs did not reply to them, and I don't have an account in otrs yet. Can you add that for me, please? Thanks!

[clo-devel] Migration status 2011-04-26
by Erik Huelsmann 27 Apr '11

27 Apr '11

Although last week's attempt to run cl-net off a network FS failed, this weekend a renewed attempt succeeded. This means we'll have completely current data on both old and new cl.net. This provides a solid basis to start migrating different services to the new machine. One of the things currently being moved is the ssh authenticated access. Other services to migrate soon are: * trac.common-lisp.net * paste.lisp.org / the bots * www.common-lisp.net / the webserver setup (with proxies and all) * the cron jobs * MTA/mailing lists * others Stelian and I are working through the steps and issues slowly on #tech.coop; if you want to discuss with us or want to know about progress or help out, come to the channel, hang around and join our efforts. Bye, Erik.

[clo-devel] File ownership: uid/gid design issue
by Erik Huelsmann 18 Apr '11

18 Apr '11

While browsing around, I noticed that we may have an issue with file ownership for Trac (but maybe wider): all files in a specific project under /project are owned by the project initiator with the group set to the unix group by the same name (all project files are world readable). This applies to all files, including Trac database. The problem arises when Trac (running as www-data under the http server) wants to modify the Trac database in the project. Since the user and group are set to values other than www-data, it can't write to the database file. In the specific case of Trac, this may probably be solved by running it against a postgresql backend instead of sqlite. However, possibly, other services [provided now or in the future] may require write access too. What's the usual way to solve this issue? Do people add the www-data user to all project groups? That doesn't seem right from the security perspective. Bye, Erik.

[clo-devel] 2011-04-15: cl-net migration progress
by Erik Huelsmann 17 Apr '11

17 Apr '11

My work on cl-net migration got stuck a little on tech.coop internal work this week. However, I'm fully back to the migration and I'm making copies of /project and /home right now. I suppose I'll be creating a copy of much inside /custom too, when the other two transfers have finished. At the same time, I'm trying to figure out how to best migrate /etc/password- and /etc/group-. Anybody here done someting alike before? I mean, I can't just copy it over, because the system accounts shouldn't be overwritten. I suppose a 'grep -v' (for inverse matching) should get us quite far filtering out system (uid<500) accounts. Another issue I'm thinking about is that we're going to switch to subdomains for hosting our services. However, the benefits of such a change seem low if we don't switch to a structure where our data is also grouped per service. Currently everything is in /project, which is grouped around projects, requiring all services to run on a single server because they need to access specific directories - one in each project. I'm thinking we should reverse the design: grouping data per service and making /project a set of symbolic links into the service directories. That way, all that's required is that the links point to the right locations in the file system, possibly NFS mount points, if the service were to run on a different server. Again, I'm interested in your comments and ideas. Regards, Erik.
