Bartosz Kowalewski updated ARIES-373:
-------------------------------------
Attachment: aries-373-20100912.patch
Hi David,
Attaching a new version of the patch (aries-373-20100912.patch). It is based on
AspectJ Runtime and Weaver (1.6.2) fetched during build from SpringSource
External repo. Equinox Aspects feature zip is downloaded and unzipped using
antrun. Two bundles from this feature (weaving hook and weaving aspectj) are
later used inside a Pax Exam test. It seems that this configuration is stable
(if Equinox Aspects 1.0 M7 are used). Unfortunately, if I switched to an older
release (i.e. 1.0 M6) tests failed. Hopefully the test setup with 1.0 M7 will
work on all machines.
I also fixed the problem with some temporary (test) bundles being left after
test invocation.
Best regards,
Bartek

> David Bosschaert some time ago contributed a set of Equinox Aspects-based
> examples showing how to use aspects to make SPI work inside an OSGi
> container. I promised to contribute an enhanced version of these mechanisms
> and integrate these into SPI-Fly /Maven projects, Pax Exam, etc./. I'll
> attach a patch with those changes in a moment.
> Few important notes:
> 1. This is not intended to be committed directly to Aries SVN. The only
> purpose of this patch is to provide initial impl that could be used when
> doing additional experiments and evaluation. The patch is dirty, I was in
> hurry when doing it and there are lots of ugly pieces of code inside :). If
> we decide to go with this approach, I'll prepare a clean patch once I'm back
> from vacation - in two weeks' time.
> 2. The problems that were identified in the discussion about using AspectJ in
> SPI-Fly haven't been resolved yet. This includes (but is not limited to):
> - being tightly coupled to Equinox; this piece of code is based on Equinox
> Aspects/Weaving; this will not work wit any other container
> - inability to tell AspectJ to run an aspect on behalf of other bundle; each
> bundle that wants to use these new features, needs to contain an aspect and
> other settings like a Require-Bundle header
> 3. This patch introduces a SPI-Consumer header and enhances the SPI-Provider
> header. A Pax Exam test show how to use this new functionality once you copy
> the aspect to your bundle and configure Require-Bundle header.
> 4. I haven't found the latest version of Equinox Weaving in any of publicly
> available Maven repos. That is why, these libraries will need to be copied
> manually to the itests project (to the weaverBundles subdirectory). I'll
> attach these bundles to this JIRA.
> This patch is huge, so I guess there might some issues with applying it. If
> you have problems with that, let me know and I'll try to generate it again.
