p2.inf setStartLevel not working [message #516932]

My feature contains a couple of plugins in one of which I have included p2.inf as below

instructions.configure=\
org.eclipse.equinox.p2.touchpoint.eclipse.setStartLevel(star tLevel:8);\
org.eclipse.equinox.p2.touchpoint.eclipse.markStarted(starte d:true);

The setStartLevel does not work when I install this feature in a product but markStarted does. The startLevel always remains at 4 default.

Any ideas?

Your syntax looks fine. (Although for some reason in your post there are
spaces in "startLevel" and "started" -- you have "star tLevel" and "starte
d")
I'd suggest attaching a debugger and walking through the "SetStartLevel"
action.

The spaces are not in the actual file, they just appeared here on the forum when I posted.

Could you please provide a reference (or any help) on how to attach a debugger (preferably the eclipse PDE debugger) to a standalone RCP product?

Thanks

Thanks. Is there an easy way to install this patch? and when would this become a part of standard p2 release?

The easiest way is to import the org.eclipse.equinox.p2.touchpoint.eclipse and org.eclipse.equinox.p2.metadata plugins including
source, apply patch and replace the plugins from your distribution with these plugins

Nice job Snjezana -- that's the problem.
One thing though is that the behaviour you are seeing is by design and so
this patch is unlikely to be applied.

When you want to provide your own custom behavior you should not be putting
this in your IU. For example another consumer of your bundle might have
totally different start-level constraints.
Instead you should provide your own IU fragment which is done by creating an
IU and setting it up with the host you want to bind to e.g.
"hostRequirements". An IU will be bound to exactly one fragment and will
choose the fragment that is the best fit so a fragment constructed in this
manner will be selected in preference to the default e.g
tooling.osgi.bundle.default IU fragment. You can still do this in your
p2.inf in 3.5.

I have faced this issue while I was trying to implement Equinox Transforms http://wiki.eclipse.org/Equinox_Transforms
The org.eclipse.equinox.transforms.xslt plugin has to be started with an eager start level (1 is recommended).
If another consumer changes this, Equinox Transforms won't work correctly.
A similar behavior is required by the org.eclipse.equinox.weaving.aspectj plugin which is described in
https://bugs.eclipse.org/bugs/show_bug.cgi?id=253244
I don't know any plugin that is designed to be run at an eager start level, but allows a client to change the start level.
