Linus snapshots are available on a 3-hourly basis from:

ftp://nl.linux.org/pub/linux/bk2patch/

People can grab the repository for use with CSSC from:

ftp://nl.linux.org/pub/linux/bk2patch/

Or using rsync:
rsync -rav --delete nl.linux.org::kernel/linux-2.4 linux-2.4
rsync -rav --delete nl.linux.org::kernel/linux-2.5 linux-2.5

Currently these repositories are updated every two hours, but if there
is a large demand I could update it every hour or even every 30 minutes.
Don't feel ashamed to put the above rsyncs into your crontabs, grab the
source and use it ;)

have fun,

Rik

Make sure you do a

bk -r admin -Znone

on that tree. We support gzipped repos, SCCS/CSSC don't.

I just started exporting this on nl.linux.org, see
ftp://nl.linux.org/pub/linux/bk2patch/README

The following command should work:

rsync -rav --delete nl.linux.org::kernel/linux-2.4 linux-2.4

[RM comments: GNU CSSC is a GPLed reimplementation of the SCCS (Source
Code Control System) framework originated by AT&T Bell Labs, which
is/was generally similar to RCS, i.e., a fairly primitive SCM that works
on a per-file level. http://cssc.sourceforge.net/ It seems that one
may first use rsync to replicate the BitKeeper archive, and then run
"CSSC get" to check out the source code modules, if one wishes to
avoid BitKeeper's proprietary licence terms but still access the
repository directly. A patch is required to the GNU CSSC source code,
as described below: ]

Whoops, forgot one thing. Take the GNU CSSC sources, they look for

^Ah%05u\n

at the top of the file. Make them accept both "h" and "H" and then it
will work. We changed it so that ATT SCCS would overwrite our metadata.

You don't need to use bitkeeper for that, you can download all the
bitkeeper changesets as patches from my ftp site:

ftp://nl.linux.org/pub/linux/bk2patch/

cheers,

Oh, but that may be useless, unless you regenerate your patches whenever
the tree is reparented. I ran into this while trying to do the same
thing. Basing it on the ChangeSet ID is a waste, and it needs to be
based on the ChangeSet key instead (the ChangeSet ID for a given key can
change when a merge is done).

Good point. I'll need to look at this more closely...

Thanks.
Note that -a implies -r. You also might want -z in there depending how
your availability of bandwidth and CPU cycles compare.

The way things are now, nl.linux.org has more bandwidth than
CPU. Using -z is a good idea though, if you've got more CPU
than bandwith.

RM adds: David Woodhouse's site publishing kernel source exported from
BitKeeper: http://kernel.teleglobe.net/pub/linux/kernel/people/dwmw2/
Offered are Linus Torvalds's master 2.5 tree and Marcello's 2.4 tree
from bkbits.net .

Hourly snapshots can easily be done if wanted.
Just a simple "crontab -e" for me.

Note they are public now, at
ftp://ftp.kernel.org/pub/linux/kernel/v2.5/snapshots/
(and I promised Marcelo I would do this for 2.4 too...)

Check out /pub/linux/kernel/v2.5/snapshots/
[updated nightly at 4:20am US/Pacific time] My script updates
EXTRAVERSION to -bk1, -bk2, etc. so they are really just like
pre-patches.

And dwmw2's per-cset GNU patches.
