I hope you guys could get xen-api and xen-api-libs to compile on the
distro that have the lasted versions of linux packages installed. ocalm.
It is impossible to get xen-api libs to compile on arch linux

Only one of us use Arch Linux, and it's not a big server distro, so we haven't tried compiling on Arch yet. I'm really not surprised xapi is broken there!

If you'd like to help port xen-api to Arch, perhaps you could start another thread with any specific errors you're encountering? Arch would be a great "early warning" distro for us, because it's always on the bleeding-edge of upstream code, and would alert us to breakages caused by kernel/compiler/etc. changes much sooner than other distros.

Hi,

Just a quick question:
- Mike showed me a document somewheree on Github that closes
item 1 ...
can somebody send me the URL. I think its a document that is
hidden in
one of the repos.

Is this what you want?

https://github.com/xapi-__project/xen-api/blob/master/__README.markdown#contributions

<https://github.com/xapi-project/xen-api/blob/master/README.markdown#contributions>

I'll be publishing a draft Xapi roadmap shortly, BTW.

Mike

And ACTION chasing:
1) Jon Ludlam (draft it today): Document how to contribut(proper
Readme
file / copy onto wiki or new website)
2) Dave Scott: document the components - list with name + short
desc +
link to repo + diagram
3) Mike McClurg: XAPI team needs to have a discussion about
bug-tracking
... I would say that there should be a public discussion about this,
once the other stuff has been resolved
4) Lars: set up meeting with James, Richard, DaveS, and Mike
Bursell to
discuss and resolve ... although I have not set up a meeting,
there has
been a proposal. Mike promised he would respond to this thread for
discussion today'ish
5) Dave Scott socialise a proposal on what is a release with team at
home ... again, I think there is a proposal that just needs to
be posted
6) John Garbutt: give techtalk to the XAPI team explaining the
external
viewpoint
7) Rob Hoes to send a link to LaTex document in source tree re
versioning scheme

Cheers
Lars

This session was about processes and practices around XAPI
and XCP.

Participants: John Garbutt, Jonathan Ludlum, Rob Hoes, David
Scott,
Lars Kurth, Julien Fourgard, Olivier Lambert

Communication
=============
* What is the Roadmap for XAPI and Roadmap process?
* What bugs are there and what is being worked on?
* Is there a way to disentagle the release of XAPI itself
from XAPI packages? Right now, XAPI releases are not itself
properly versioned and released which is causing issues
and confusion in XAPI packages and distributions.
Solutions could be
** Source/other release of XAPI (outside of package)
** Could just be a tag in GIT
** Should have an identifiable version number

More practical questions
========================
* How do you contribute a patch (not documented)?
* How do you raise a bug (not documented)?
* How does a release happen?

Contributing a Patch
====================
NOW: not documented

SOLUTION: Github and pull requests
(+tagged message or digest on list)

Stuff that needs to happen first
* XAPI iser and dev have to be split
* Proposal for list names: xapi-users and xapi-devel

ACTIONS:
* Jonathan L (draft it today): Document how to
contribut(proper Readme
file / copy onto wiki or new website)
* Dave Scott: document the components - list with name +
short desc +
link to repo + diagram

How do you raise a bug (not documented)?
==============================__==========
NOW: http://wiki.xen.org/wiki/__Reporting_Bugs_against_XCP

<http://wiki.xen.org/wiki/Reporting_Bugs_against_XCP>
For nor now, list is good enough. But long term want a bug
tracker.

ACTION: XAPI team needs to have a discussion about it
Constraints
* Publicly accessible
* Hosted outside of Citrix
* JIRA looks like a good solution, but need to get
it implemented and needs sysadmin support

Roadmap Planning / Process
==========================
JIRA tickets for features/improvements/bugs? Maybe a little
much.

Lars suggested to use something very lightweight: if you
focus too
much on tools you lose sight of the essentials. For Xen HV a
high-level list and polling status on the mailing list works.

John: as an external developer, John would want to see what
is coming
and where there are opportunities to contribute.

List of desirable items from a community perspective
* Have clarity of what are people working on
* Clarity on what is coming soon (with a view of being able
to test)
* Ability to collaborate on what others are working on
* Not start something which somebody else started
* Points in time to facilitate collaborative planning
(requires a fixed release cadence, or long term predictable
roadmap)

ACTIONS:
* Lars: set up meeting with James, Richard, DaveS, and Mike
Bursell to discuss and resolve

What is a XAPI release?
=======================
Problem: confusion on "what is in XAPI packages" (e.g. if
you picked
up XCP-XAPI packages from Debian it is not clear what is in it).
Working on CentOS-XAPI integration I have no idea what is in the
package and thus what I need to test.

High level solution:
* Some label + numbering scheme/naming convention in GIT repos
** Something matching major dependencies
** Release (or release notes) defines what combinations
have been tested
** Some convenience mechanism for distros, such as a
tarball to download (which excludes the distro package)

QUESTION: should the packaging be separate from distro packaging
(which includes the ISO)

ANSWER: packaging should be separate; there may have to be
different
models per distro

ACTION:
* Dave socialise with team at home
* JohnG: give techtalk on external viewpoint

API Version
===========
NOW: List on Citrix website in the release notes which is
generated
from source

Issue: it should be clear which XAPI version maps onto APIs

Action: Rob Hoes to send a link to LaTex document in source
tree.

Should build the LaTex document, include it into tarball and
advertise
it as part of the XAPI release.
