Re: [cross-project-issues-dev] p2 repositories ... we can do better

BTW, in case people didn't know.  As of 0.14, Tycho fully supports using p2.inf during p2 repository creation.

It looks like some of this stuff should be doable using Tycho 0.14 and the Tycho P2 Extras plugin.  Included is the ability to run the various Ant Tasks provided by eclipse.

having to go to the cli to tweak this stuff is a non-starter, i have a
mechanism leveraging that for the packing process and I dislike that
immensely

anyway, i am already in java code and mucking with the xml fixing
checksums and the leftovers from the packing process so probably
easier to just add a couple of properties for these settings and
inject them into the xml at that point

not ideal but little about the situation is so will make do with what I have

I think your eyes glazed over reading my original note before you got to
the part where I said there is already such a tool. See

Feel free to use/copy that as you'd like.

The advantage of having a "stand-alone app" or tool (not only as "part of a
build") is that is allows you to change the properties after the repo is
created, as is sometimes required, after moving or mirroring the repo
elsewhere.

Good luck,

Not sure for tycho but given some time I could have that in the
signing plugin in an hour or so I would think.

I'll see if I can scrape some time together to get that support added
in, at least in the interm until tycho could support it

cheers,

can you give me a specific example of what that xml (assuming that
would be in some of the xml metadata) would look like?
= Support for p2.mirrorsURL =

According to http://wiki.eclipse.org/Equinox/p2/p2.mirrorsURL just add:

<property name="p2.mirrorsURL" value="
http://www.eclipse.org/downloads/download.php?file=
{repository_path}&amp;format=xml"/>
Since webmaster thinks that we have been hit by this issue recently (
https://bugs.eclipse.org/bugs/show_bug.cgi?id=373352) this makes me think
even more about how to integrate this into our builds. As last means of
resort I'll write a bash script that unzips artifacs.jar, adds the property
to the artifacts.xml, and zips the file again.
But I wonder how much effort it takes to add this in Tycho's
eclipse-repository packaging since tycho generates these files?
It wouldn't be specify to Eclipse; just a generic support for properties
- I think.

= Adding support for p2.index =

The file looks like this:

  version = 1
  metadata.repository.factory.order = compositeContent.xml,\!
  artifact.repository.factory.order = compositeArtifacts.xml,\!

Whether it's "xml" or "jar" should depend on the "compress" property we
already specify in the eclipse-repository.

= Enabling download stat in your repository =

And if we are already on defining properties: to enable download stats
it's...
...for artifacts.xml/repository:
<property name='p2.statsURI' value='http://your.stats.server/stats'/>

...for bundles:
<property name='download.stats' value='test.plugin1.bundle'/>

http://wiki.eclipse.org/Equinox_p2_download_stats




So, in theory it's just adding properties and looks from outside like a
simple thing to do. But how long it takes to implement it - at least the
p2.mirrorsURL feature - I've no idea. But maybe a tycho committer knows
better?

  I suspect is
possible but I also think it is probably more appropriate to have that
support in tycho

the signing plugin is really just a hack to support this aspect of the
eclipse requirements that is outside of the traditional tycho
workflow...having said that we can always put another hack or two into
it :)

cheers,
jesse
