+1 to not using feature includes on Orbit bundles from project’s features. The 
actual presence of Orbit bundles in project’s repository is not particularly 
harmful as long as the dependencies on these bundles are expressed using 
version ranges.

That’s one implementation approach of achieving #1. There are other options 
that I have outlined in another response.

It’s not a good idea to mix project release repositories and simrel update 
stream. The project’s release should be a fixed point in time, so it’s entirely 
appropriate for the repository to contain the necessary dependendencies at 
versions used during the release process. 

Using an associate-site in the manner you are proposing would mix release 
artifacts and a certain particular update policy in a way that would make it 
difficult for other update policies to exist. The problems with this are 
discussed in more details in other threads on this mailing list. In short, to 
maintain the flexibility of supporting multiple update policies, project’s 
release repositories should never use associate sites (referenced 
repositories). Only an update stream repository (such as simrel or one 
maintained by the project) should do this.

Thanks,

What about the following policy?

1) Ensure that none of the features contributed to simrel include any Orbit 
bundles, but only refer to them via dependencies (and ensure that proper 
version constraints are used in addition).
2) Use specific all-in-one features that include the required Orbit bundles 
(and the features deployed to simrel), but only use them to produce 
self-contained local drop files (zip).
3) Do not publish all-in-one features on your local update sites either, but 
rather have your local update-sites refer to the simrel update-site via an 
associate-site entry (so Orbit dependencies get pulled in from there).

With 1) we would have a single authority that controls which Orbit bundles are 
actually provided in a release, namely the simrel aggregator. 2) would cover 
your use case, Ed. 3) would ensure that newer Orbit bundles (added in a 
maintenance release) would also get picked up when installing from a local 
update-site.

Cheers

Hi Konstantin

I have no idea how a download ZIP can easily mirror something.

But I presume what you really mean is that we should produce two 
ZIPs/categories.

- A contribution ZIP/category that replicates the features contributed to 
SimRel.
- An All-in-One ZIP/category that additionally bundles Orbit facilities 
avoiding the need for users to learn how to include Orbit in the available 
sites.

I would advise strongly against using the feature includes directive for Orbit

the produced project repository, it also locks you down to using that one 
version of the bundle and we end up with multiple versions of various bundles 
in the install, often for no good reason. It’s easy enough to mirror the 
required Orbit bundles using a separate step at the end of the project build 
and be free to require the bundle via whatever version range is most 
appropriate.
 
If everyone did this and simrel aggregation included the latest Orbit 
repository, the result of aggregation would contain fewer duplicate Orbit 
bundles without requiring projects to issue a new release just to move to a 
newer version of an Orbit bundle.

Hi David

Interesting if you're right. I thought projects needed to bundle what wasn't 
bundled upstream. Thus OCL bundles LPG since no one else does. OCL includes 
ASM, Guava that someone else bundles.

You suggest that OCL could stop bundling LPG since LPG would appear in the 
SimRel repo automatically.

However OCL still needs to bundle LPG in order for the install from ZIPs to 
work offline. AFAIK there is no SimRel ZIP distribution. If there was, it would 
probably be so big that few would use it. However if there was a 
used-in-SimRel-Orbit ZIP distribution that could be useful and could help you 
enforce limited usage.

Granted, there should not be anything breaking, if you simply took a what ever 
was there, within some specified range, but especially with third party 
bundles, you never know. Some are real good at following good versioning 
practices, some are not.  Plus, keep in mind, the "aggregated repository" is 
supposed to be a simple grouping of a subset of what ever is in the project 
repositories. We do not want a situation where if someone installs directly 
from "your" repository, they get one set of things, and if they install from 
the Sim. Release repository they get another set of things. Maintenance would 
be very difficult, then. To repeat, that's off the top of my head. Maybe you 
meant something else.

Hi David,

could you please clarify why exactly updates would be needed from projects 
because of changes to Orbit bundles? Does it result from the fact that Orbit 
bundles are actually re-bundled by project features? Or from the fact that 
requirements on them are specified too restrictive within project bundles or 
features?

I’m not sure if this is already covered by some simrel reports, but IMHO we 
would be pretty safe if we ensured that

1) no Orbit bundles were actually re-bundled in project features, but only 
required by them, and that
2) dependencies on Orbit bundles or packages would be specified in line with 
the respective Orbit main releases (based on proper version ranges),

because the aggregation could then pretty much control which Orbit bundles get 
pulled in. If we would in addition impose the same restrictions on Orbit 
releases as on project releases (namely that updates including breaking changes 
are not allowed in maintenance releases), I would assume no project should 
actually have to update its contribution for a maintenance release.

Cheers
Alexander

HI

"commons.collections" doesn't seem that well used. No version of it is my 
workspaces, so QVTd, (Xtext, EGIT, UML, QVTo, OCL) cannot have a dependency on 
it. No re-contribution needed.

Ed, 

Thanks for bringing this "no maintenance, no new Orbit" issue to my attention. 

While the Planning Council does not like to "make" people do extra work they 
would not normally do, I believe it was the intent of one of our requirements 
[1] that the latest Orbit be consumed every update release -- if there has been 
a new Orbit "released". Most often there is not a new Orbit release, since we 
in Orbit do that only for significant issues. This time, it was only for the 
'commons.collections' security bug, and a bad bug in Ant 1.9.4 that drove us to 
provide Ant 1.9.6. [2]. 

While I will not say you *have* to update and provide a new build, I would 
encourage you to, as well as anyone else who uses "commons.collections" since 
we don't want to "spread around" a package that has known security flaw in it. 

As far as I know, in most cases of installing and updating people will get the 
correct, fixed version of that bundle, but am not positive that is always true 
so I hate for it to be the available from any of our "most recent repositories" 
(Simultaneous Release or not) -- after all, the b3 aggegator is including it 
for some reason -- so someone must say they require it?  

But I am also not the "security policeman" that will say that bundle must be 
expunged from all current downloads. (If I recall, the security issue only 
applied to specialized cases ... but, if you were running in that case, it was 
a bad security bug possibly leading to a malicious person "executing arbitrary 
commands". 

I have opened bug 487285 to investigate or discuss this issue further. [3] And, 
 I will put this on future Planning Council agendas to see if we can word that 
requirement [1] better so that all projects know better what is expected of 
them.

Thanks again,

You might want to review your query. qvtd.b3aggrcon was last changed by me on 
26 June, and by you on 14 July.

We are certainly not sleeping, and did not forget to update. Just working very 
hard to support the functionality required for graduation to 1.0.0.
And ... worst of all, IMHO, some "old" third party jars are still being used, 
which implies to me someone is not using the latest version of Orbit 
(R20151221205849). 
But if a project has no maintenance to contribute, I thought no 
rebuild/contribution was required and so of course an old Orbit would be in 
use. (I don't think that QVTd imposes tight bounds on Orbit contributions.)
