Re: [eclipse-pmc] Re: FW: [tools-pmc] Request to approve XULRunner as an exempt pre-req

The vast majority of the platform however does work.  Not being able to use the browser widget is not a big impact to the SDK or even SWT on linux IMHO.  Suspect there is not a single metric but more of a judgement call.  That is why the PMC and project leadership is involved in evaluating and approving these things.

My understanding is that if you don't have xulrunner on linux, the SWT Browser widget doesn't work. I know that from first hand experience. So how much of your plug-in needs to be dependent before it qualifies for IP approval?

Agreed.  the platform use of xulrunner is a works with IMHO.  The vast majority of platform users never need or run xulrunner and everything is fine.  if they want to use this extra feature that integrates xulrunner then of course they need xulrunner.  As David points out, ATF is different cause its entire being is based on this (well, more or less) so, like gcc for cdt, it needs it and should be an exempt prereq

Oh, what have I started. :)

I will say that in my chats with the Platform, I think they (rightly)
count their dependency as a "works with" type of dependency, as per

and I get the impression CQs do not have to be open for "works with"
dependencies ... but, yes, they should be in IP Log (and it probably is,
though I haven't checked).

Wayne can clarify if I've gotten the wrong impression about the CQ for
"works with" dependencies.

And "works with" is a little different than the "exempt pre-req" we're
discussing in Tools PMC. The primary difference is the ATF function pretty
much won't work at all without it.

Also, of course, each Project must document and get approved their own IP,
so technically what the Platform does would not directly impact our Tools
PMC work. Precedents can help, but there are sometimes subtle differences.

Hope that helps,

I think our process may have broken down here a bit.

In order to use third-party software from an Eclipse project, we need to
have a CQ requesting that it be declared an exempt pre-req (i.e. the
user must have it installed on the machine for the Eclipse code to work)
or as a Works-with (i.e. if the software is there, the Eclipse software
will use it).

Anthony, can you please make sure that a CQ gets created on behalf of
eclipse.platform. I'm pretty sure that we can get the EMO(ED) to sign
off on it and make things right.

Hi Team,

1+, the SWT team also requires XULrunner be installed, see , so this really is
no different.

+1  XULRunner is dominant in this space and should be an exempt pre-
req.  There are really no other choices.

PMC Colleagues,

The ATF project would like to require ("pre-req") XULRunner to be
installed by users of ATF since for many of their main functions to
such as debugging, css outlines, etc. it is required.

As per Eclipse's Third Party Dependencies Policy, for them to do
this, the
Tools PMC and the EMO must agree that is the correct classification
for a
pre-req, which would not go through IP review. See Third Party
Dependencies Policy for complete details, but the section specific to
'exempt pre-reqs' is as follows:

3. All "pre-req" dependencies must be declared to and approved by
the EMO.

4. "pre-req" dependencies fall into two cases: "exempt pre-req" and
"non-exempt pre-req". This
determination is made by the EMO with input from the relevant PMC and
project leadership.
a. A pre-req may be classified as "exempt" by the EMO if the
software is
pervasive in
nature, expected to be already on the user's machine, and/or an IP
would be
either impossible, impractical, or inadvisable. Exempt pre-reqs can be
approved for use
by the EMO without IP review. Examples: Windows XP, Sun JRE.
However, an
 pre-req may be disallowed by the EMO at its discretion.

I think XULRunner, in a generic form, qualifies as an exempt pre-req
it is pervasive. It is distributed with most or all Linux
and is a sub-component of Firefox, a wide-used browser with is readily
available for all major platforms and architectures.

The ATF team will submit JavaXPCom in a CQ and they will distribute
for major platforms and architectures, as a fragment for one of their
plugins (or eventually from the Orbit project). JavaXPCom is a
small interface to XULRunner APIs (approx. 1000 files) so it is
to review and distribute it. It is this distribution of this interface
that allows them to interact with XULRunner in a more generic
fashion and
make use of what ever happens to be installed on a users machine.
That is,
they would not need a specially compiled version of XULRunner.
(There will
of course be some limits, as to exact version, etc., but that's
unknown and would not substantially change the status or request to
consider XULRunner as an exempt pre-req.) See also CQ 3551 for some
discussion of this general issue.

If we, the Tools PMC, agree with the exempt pre-req classification,
the ATF Project can take this forward for approval by the EMO.

To document approval, please respond with +1 to this list.

If you disagree, or would like to discuss more, please raise the
here, in the CCQ 3551, or set up a phone call to discuss in more
