Hello, i'm no more on the list (too less problems with AP :) -> please 'reply to all'. The cache here is about 3.6 GB, and unfortunately my i can't give the cache more than 4GB total (seperate partition) without rebuilding the whole partition table... I switched from debian testing to unstable, yesterday, and there's still stable + testing stuff in the cache. Plus repositores for obsolete backends that i don't use anymore. However, i can find files from 2005 in the cache, and more than 1 version anyway. For example, openoffice.org_2.0.0-5_i386.deb openoffice.org_2.0.2-1_i386.deb mozilla-browser_1.7.12-1.1_i386.deb mozilla-browser_1.7.12-1_i386.deb mozilla-browser_1.7.8-1_i386.deb mozilla-firefox_1.0.4-2_i386.deb mozilla-firefox_1.0.6-5_i386.deb mozilla-firefox_1.0.7-1_i386.deb The latter, found in debian/pool/main/m/mozilla-firefox, is a good example for a related issue, that is, changing package names and/or classification. Debian unstable has firefox version 1.5, which i can find now in debian/pool/main/f/firefox: firefox_1.5.dfsg+1.5.0.1-4_i386.deb mozilla-firefox_1.5.dfsg+1.5.0.1-4_all.deb The question is, can i have AP 'clean up' all files that are older than a specified time regardless of the number of versions ? Can i modify the config temporarily to delete anything older than (today) 1 day, and that would leave me with 'sid' only ? These are the related config settings: min_refresh_delay = 1h cleanup_freq = 1d max_age = 1d max_versions = 1 dynamic_backends = off So, how can i have AP clear the old files ? |

This particular problem is very hard to solve, and I don't think it is worth
spending time trying to do this.

Your configuration as shown should work... but only if a-p has been running
for a whole day. Try setting cleanup_freq to something small so the cleanup
cycle is started quickly, e.g. 30m.
Alternatively, use a find command to remove the files from the cache:
find /var/cache/apt-proxy/* -amin +1440 -exec rm {} \;
(1440 is 60*24 minutes = 1 day)

Hey, wait ! Looks like i misinterpreted it.
I thought it would check the date...but it checks uptime ?
That would explain a lot. I shutdown the box every day.
I just thought the cleanup didn't work correctly, somehow.
Hmmm...i still would prefer to run the cleanup only on demand,
i do compiling/installing more often, and the ap background process could=20
slow down things when i like to have 100% cpu myself...
There's no commandline to trigger cleanup, right?
Perhaps simply restart then with cleanup_freq =3D 1m...However:
Tried it right now, but i can't see any twisted process activity,=20
nor anything in the ap log ?=20
How about telnet, connecting to the running server ?=20
Can i trigger something that way ?
Oh, I just see,=20
"Warning: As of Twisted 2.1, twisted.protocols.telnet is deprecated. =20
See twisted.conch.telnet for the current, supported API."
(Plus general warning for twisted 2.2.0 but normal operation are ok, so...)
I never used the python thing, and have no clue what i could do with it=20
anyway, is there any information available ?
I just enabled the config options for port 998 and restarted ap and tried a=

simple telnet connect but i can't get any connection there, it seems to work
however on the normal http server port 9999. (without password request...?)

so why not 9998 ? Is there a mistake ?
I just installed identtestd, that works ok too.

ok that's what i wanted to hear, anyway :)
Though it's coming too late. Cache ran out of space, and i decided

think most packages will be cached again very soon.
Pity, but not critical (by now).
At this occasion i noticed that AP keeps a direct stream even if it can't=20
use the cache anymore. Well done.

The cleanup does a lot of sleeping in between each disk access so that it does not disturb any busy processes. It should use less than 0.5% CPU, depending on your processor speed. > There's no commandline to trigger cleanup, right? No, but it sounds like it might be a good idea to add this. > Perhaps simply restart then with cleanup_freq = 1m...However: > Tried it right now, but i can't see any twisted process activity, > nor anything in the ap log ? That's strange. I see activity on my version, although I am working on a different version of the code. > How about telnet, connecting to the running server ? It should be possible, but I can't get this working properly either - maybe it is because of the deprecated error that you saw. It is probably best for you to use find to remove the files for now, until bug #343922 is fixed. > I just enabled the config options for port 998 and restarted ap and tried a > simple telnet connect but i can't get any connection there, It will only enable the telnet server if you specify a port, username and password. Maybe something was not spelled correctly. > it seems to > work however on the normal http server port 9999. (without password > request...?) That is the HTTP socket. You can't do telnet commands to this port, only requests for files. > I also dug holes into xinetd / libwrap / ident so they should be ok with > telnet queries. libwrap (hosts.allow) is open for "apt-proxy:" and there's > anyway no port assigned enywhere (in /etc/services) .... > so why not 9998 ? Is there a mistake ? Have a look at the debug log. It should say if it is listening. My version says: 2006/03/01 10:31 GMT [-] twisted.manhole.telnet.ShellFactory starting on 2222 2006/03/01 10:31 GMT [-] Starting factory <twisted.manhole.telnet.ShellFactory instance at 0xb77611ec> (my telnet socket is port 2222) > At this occasion i noticed that AP keeps a direct stream even if it can't > use the cache anymore. Well done. Erm, that is just a lucky accident :) Chris |
