Hi all,
attached is some work I've done regarding bittorrent...
Since this seems to work and since it can be useful also for those that
are working for the bittorrent porting (in particular for Bernard) I've
decided to post this patch (based on the developer trunk).
I've used the standard bt client (written in python) both for clients
and image server, so I've included both the python interpreter and
bittorrent scripts in BOEL binaries.
Bernard is using libBt, it seems more light since it doesn't require
python, maybe it could be interesting do some tests to evaluate the
difference in performances between the two products.
To use my bittorrent patch you've to start the tracker and the first
seeder on the image server, simply using the following command:
# si_startbttrack --image_server <ip_image_server> --image <image_name>
This command creates also a single tar file for the image specified by
comdline; run with --update_image to update the tar file.
I've not written the si_stopbttrack command, even if it is very
simple... but for now you have to stop it only killing the tracker and
the seeder manually... ;-)
For the client side I don't use flamethrower, the bt client works alone
without further packages (except python, of course).
You must only define BITTORRENT_STAGING=<dir_path> as a kernel boot
parameter. In this way the bittorrent protocol is used to deploy the
image in the clients. First of all the image is downloaded in a staging
directory (the path is specified by the parameter), then it is untarred
in /a/ (the root directory of the installed fs) and the tar is removed
when the exctraction is completed.
If the client has not a lot of memory, like my test machine :-(, you can
deploy the tar file using the client disk space, for example I usually
use BITTORRENT_STAGE=/a/tmp... otherwise if you have enough RAM, to
increase performance, is better to deploy the tar file in tmpfs (for
example using /tmp - we can assume this as the default option).
If you can do some tests let me know your feedback... in particular for
Bernard that it's working hardly with bittorrent... ;-)
Best regards and happy new year!
-Andrea
