Re: [cross-project-issues-dev] GEF Oxygen M1 contribution only partially today

Almost there: https://git.eclipse.org/r/78708

We're just having a problem with the TM repo, which PTP depends on.

They have to be enabled at the same time. That is our life at the moment.

My point in the past was to not disable features between one release to the next, e.g. Neon to Oxygen. Because this…

It’s much easier to disable projects that drop out than re-enable ones that have always been there.

CDT  is not providing a new M1 build but needs to enable itself to use the Neon.0 build.
There are all kinds of project dependency loops though, and I can't enable CDT without
breaking the build.  While my dependencies also can't enable themselves because they
are waiting for CDT.

Houston, I think we have a problem.

Hi


In the past Doug has expressed considerable scepticism about the value of M1, and there has been no CDT M1. Retaining the Neon.0 contribution makes sense.


You certainly need to have a coherent set of enables to get things to work. I'm not clear what value Gerrit adds other than introducing a confusing tool with extra opportunities for confusing failures; do you really want to wait for someone to approve/review? This is cutting edge releng by responsible committers. I find a traditional direct push works fine, just so long as you remain online to revert any accidents promptly.

Then what we can do is enable both CDT and PTP in the same contribution.
I'll push a path to Gerrit to see how that goes.

Hi,


If you merge a breaking change in master, then nobody will know if further changes break something or not. As far as I can see, the validation fails on the first error.

Actually, I believe PTP depends on CDT for other plugins.
So we have a dependency loop at the project level, although everything works at the feature/plugin level.

I'm leaning towards pushing the CDT enabled contribution to SimRel even though it currently fails.

Opinions?

CDT is ready but dependent of org.eclipse.remote.core which is part of PTP (although only hosted, I believe).

Hi again,


I want to describe the effort I have spent in the last hours for trying to enable the DLTK project - a project with rather small number of dependencies.


1. I tried to enable the whole DLTK contribution. The validation failed because Mylyn was disabled.

2. I disabled the DLTK integration with Mylyn. The validation failed because RSE was disabled.

3. I disabled the DLTK integration with RSE. The validation failed because Linux Tools was disabled.

4. I noticed in Gerrit that the Linux Tools team was trying to enable its contribution, but the validation failed because CDT was disabled.

5. I disabled the ShellEd feature of DLTK. The validation failed because EMF was disabled.

6. I disabled the Tcl features of DLTK. Finally, I got a successful validation.

7. I partially enabled the DLTK contribution with just the DLTK Core and Ruby features.

8. I tried to enable the TM/RSE contribution (I am committer there too). The validation failed because TM Terminal depends on org.eclipse.remote, which is disabled.

9. I disabled the TM Terminal features. I got a successful validation.

10. I enabled just the RSE feature of the TM contribution.

11. I enabled the DLTK RSE feature. Still there DLTK feature that cannot be enabled.


I've spend quite some effort to achieve the above. I am not sure what is the return of this effort. And I am still not done with enabling DLTK. I cannot imagine what it would take to enable a more complex project like Andmore. Building meaningful EPP package would be another interesting challenge.

Hi

We (EMF Parsley) depend on Xtext as well (besides EMF).  It's not clear
to me what we should do... add our p2 site to the simrel and push for
review and that will fail?  Or something else?

thanks in advance
