[emft-dev] Should there be an EMFT Aggregate Update Site? (was Re: Texo build on modeling download pages)

You cannot merge your updates into the larger EMFT update using the simple unpack-a-zip method. **DO NOT** point your promote script at an existing update site or it will destroy it.

If you want an aggregate EMFT site, I suggest you look at using the Buckminster Aggregator [1], [2] to collect a number of sites into a single directory and regenerate the required metadata at the same time.

[1] [2]

Frankly, though, I think each project should maintain its own site to avoid collisions and coordination problems. For an aggregate update site containing all of EMFT, there's Helios. Does EMFT really need its own? If so, this needs all the projects to agree to a whole new mechanism, workflow and schedule of aggregation. It's easy enough to set up the script to run via a crontab to aggregate the projects' sites into a single site (or 3: interim, milestones, releases). But you need to have someone "own" the process and make sure that if it fails it gets re-run, or polices the projects who contribute to it to ensure there are no missing deps in the aggregator script.

You can also get fancy w/ the aggregator and move features into categories, or add associate sites [3]. Here's an example of that:


Recommend opening a bug and cc:'ing all the project leads so that everyone's aware of this new coordination plan.

Hi Nick,
Thanks for the answers. The promote.xml nicely creates a texo specific
update siite here:

this because I give this as the targetUpdateDir.

However, I also want it to be placed on this update site:

Should I do this by just changing the targetUpdateDir? I guess so but
what is a good syncmethod setting.

If I choose replace as the syncmethod will then only Texo builds be
replaced or will the complete update site be replacecd by Texo (not what
I want as I would delete also the EMFT things there).

I have started to use the promote.xml script (see the output below). A
question I have, how are the EMF update sites updated? It does not seem
to happen with the promote.xml I am using.

You give it the folder in which the Update zip is found, and it
unpacks it into the directory you specify. Easy-peasy. Perhaps your
zip has some weird non-standard name? Or isn't a zip? Maybe you want
to just add a <copy> step to the end of your promote.xml script to
simply copy the unpacked site to its final resting place on



Another thing: I put the update site zip in the drop directory but the
zip link is not shown. There seems to be a mismatch between what the
modeling download page expects and the name of the Update zip file. The
update zip file has this name:

The download page shows this:


Two issues:

a) build.cfg file is missing
b) filename doesn't follow the usual pattern. Go look at how your
Teneo zips are named and follow accordingly. Hint: remove "-0.1.0"

can the modeling download page to be changed to
not show the links/groups for which there are no files?

Yes. Go edit www/modeling/emft/downloads/index.php and add/remove
entries. Same process you did for Teneo when adding EclipseLink. You
may want to look at www/modeling/emf/downloads/index.php for examples
of files which have been deprecated / added to EMF (Core).

You could also trash the downloads page entirely and go with something
lighter-weight like this:

(or perhaps something more stylish, but just as simple.)
