[pkg-lighttpd] Bug#597643: lighttpd: Permissions break on upgrade when running as non www-data user

[Jon Daley]

Package: lighttpd
Version: 1.4.28-1
Severity: normal


I run lighttpd as a regular user, instead of the www-data user.  This is primarily due to the concern in bug #573320, and since it this is one user machine, I'd rather have them run 
as themselves than letting them ftp, etc. as www-data.

That all works fine, however, I upgraded the other day, and the upgrade script must include a 
chown -R www-data.www-data /var/log/lighttpd and 
chmod -R wwww-data.www-data /var/cache/lighttpd

as everything broke after the upgrade.

The log directory was easy to spot, but I didn't notice that the cache permissions had been reset until I was debugging a 413 Request Too Large error, which turned out to be the 
permissions were wrong and nothing to do with the size of the request.

Perhaps the chown should only happen on install, and not on upgrade?
Or maybe check the server.username/group?
Or at least warn the user that you are changing permissions, so he can manually put them back.
