Re: [Xen-devel] Outreachy bite-sized tasks


Thank you for the proposed tasks. I would like to work on the second one, 
fixing the return codes in xl.

First of all, thanks for your interest in the Xen Project, and for wanting
to participate in Outreachy.

Both of you have expressed interest in the "QEMU xen-blkback performance
analysis and improvements" Outreachy project, and AFAIK both of you still
need to perform your initial contribution.

I've found a couple of small tasks that you can perform and should allow
you to complete your initial contribution to the project:

 - The first one is related to xenalyze, and it consist in creating a
   header file that can be shared by both the Xen kernel and xenalyze.
   You will need to move the TRC_ defines found in sched_credit.c and
   sched_credit2.c to a header that's shared with xenalyze and then
   replace the usage of TRC_SCHED_CLASS_EVT with the defines in the header
   file [0].

 - The second one consist in fixing the return codes of certain xl
   commands. There are commands in xl that will return 0 (SUCCESS) even
   when failing, which makes it very hard to write scripts that make use
   of xl. A list of those commands can be found in [1], together with some
   preliminary patches. Please note that those patches have comments that
   you will need to address, and that you should also need to preserve the
   original authorship of the patches plus yours.

I encourage you to read the wiki page about sending patches to xen-devel
[2], it should guide you through your first steps on using git and
creating suitable patches.

Also, please note that this is an open source project, so you will need to
coordinate in order to figure out which task are you going to take, in
order to avoid clashes or duplication of efforts.

If you have further questions, either reply to this thread (keeping
the xen-devel mailing list on the Cc), or feel free to start another one
if you think it's more suited.
