Is there anyway we can tell if the main problem is new checkouts or updates? I
ask because it seems the main problem is new checkouts and cpu seems less of a
problem than bandwidth. At least it seems that way as I have read this thread.
Here is my thinking on the matter. I update my repository about 3 times a
week. If this kind of use is OK? Then my proposal could be something along
these lines.
1. Weekly cvs tarbals.
2. anon cvs with checkout disabled. cvs only has update ability ( so users
can update the tarball only). Tarballs could be bittorent pushed if wanted.
3. Have a "recomended" update script downloadable from one of the sites
get-e maybe.
or if you wanted to go really crazy. Require login for anon and sign up for a
login on get-e maybe. Do some minor hacking of cvs,git,svn or something that
provides the following.
1. use sqlite or berklydb to track users a little.
2. limits the number of checkouts. (say one per 3 months)
3. limits the number of updates. (say 3 per week :-))
The above has the disadvantage of not scaling well across mutiple cvs mirrors.
However if the web site knows about the cvs mirrors it can send new users to a
mirror say round robin or all mirrors can have a full user list updated by the
web server say rsync style or even scp on a timer.
If your are really interested in one of these options I can see about making
the changes to cvs etc. There maybe many other reasons this is not practical
just thought I would share.
As a casual user I really don't want to lose cvs update but I understand if
that is what is needed (not using gentoo btw). I watch this project very
closely though I have not been envolved much ( 2 patches weee ). Anyway I hope
this is a help not hinderance to this discussion.
