Re: [equinox-dev] OBR


I have been using OBR implementation from Apache Felix and it uses "BundleContext#createFilter" to create the filter which throws the exception in the equinox framework at the end. So if I don't modify the bindex not to generate the < or > operator,  the repo xml can't be digested in the OBR bundle for bundle resolution in the framework.
By the way, do we also have OBR implementation from equinox?

Sincerely,
ChangWoo Jung

Peter, who parses the filter? If OBR uses a different syntax from the Framework spec then the FrameworkUtil#createFilter or BundleContext#createFilter cannot be used. Who is throwing the syntax error in this case? The Equinox Framework implementation of the OBR implementation?

This is not really true. The OSGi filter and the OBR filter are not required to be the same. RFC 112 specifically allows the > and < (as well as some other operators).


Kind regards,

This may be a problem in the tool (from OSGi) which generates the xml. OSGi recently decide to add < and > to the set of filter operators. But this is not in the 4.1 spec. It will be in a future spec. So the tool which generates the xml should not use the new operators.

Re: [equinox-dev] OBR



I guess I found little bug in the generated OBR repo (
http://download.eclipse.org/releases/europa/repository.zip)
The generated filter seems to be incorrect which throws exception in the runtime.


For example, Jetty Http Service (org.eclipse.equinox.http.jetty), has dependency on "javax.servlet" which is shown as
Import-Package: javax.servlet;version="[2.4.0,2.5.0)" in the manifest.


It turns out be generated like below, (which seems to be incorrect), so it throws "InvalidSyntaxException" when equinox tries to create the filter upon that.


<require extend='false' filter='(&amp;(package=javax.servlet)(version&gt;=2.4.0)(version&lt;2.5.0))' multiple='false' name='package' optional='false'>

Import package javax.servlet ;version=2.4.0

</require>


I guess there is minor bug on creating filter and after applying my private fix it seems to be working.

wrong: filter='(&amp;(package=javax.servlet)(version&gt;=2.4.0)(version&lt;2.5.0))'

correct: filter='(&amp;(package=javax.servlet)(&amp;(version&gt;=2.4.0)(&amp;(version!=2.5.0)(version&lt;=2.5.0))))'


Which component will be the right place to report a bug against that i can attach my fix there as well? Any pointers?

Thanks.

We currently do host an OBR repo with the major releases. Don't remember the URL but the required repository.xml/zip file is there for Callisto and Europa. The OBR client code may be interesting but our strategic direction is p2. For the most part p2 has (or can be made to have) the same functionality as the OBR client but goes further towards solving the wider range of problems we see in the Eclipse provisioning space.


I am all for supporting the use of OBR repositories in the sense that some people will make their function available that way. Given the p2 work however, it would be more interesting (to me at least) to write an OBR repository adaptor for p2 than to use the OBR api. Further, I hope that eclipse projects will feel comfortable making their content available as p2 repositories so that the Eclipse user community is not put in a position of having to get many different provisioning clients.


In short, we in p2 would very much like to have your interaction and participation in making a provisioning solution that solves your needs.

[equinox-dev] OBR










Hi,
I'm wonder if any work has been done within Eclipse to deal with OBR
repositories, and if so, how can I get access to that. If not, and if no
one has a better idea, I'm planning to start an IP-zilla to get the
Apache Felix OBR approved since we will want to map that kind of
repositories in Buckminster and also provide OBR's as an alternative to
update sites in the spaces project.

Regards,
Thomas Hallgren
