Thomas Draier commented on FELIX-1851:
--------------------------------------
Hi,
The fix that has been submitted here only works when you have the
"felix.fileinstall.bundles.new.start" set to true - when auto start is not used
, I have exactly the same issue - bundle is restarted first by the framework,
then by the refresh.
I did a patch to handle this case - can you confirm the patch is correct and
can be included in a next release ?
Regards,

> Project: Felix
> Issue Type: Bug
> Components: File Install
> Affects Versions: fileinstall-1.2.0
> Environment: generic
> Reporter: Sahoo

> I am observing that bundles watched by fileinstall (1.2.0) are getting
> stopped & subsequently started twice when they are updated. First time, they
> are stopped and started by a call to update() and then because of a call to
> refreshPackages(). The scenario where this is happening is given below:
> bundle A exports package p and is tracking service of type p.Foo.
> bundle B imports a package p from A. It exports a service object with the
> service interface p.Foo.
> I am updating bundle A and it is getting stopped and started twice.
> The explanation given to me (thanks to Richard) is that:
> "The update operation is defined as first stopping a bundle and restarting it
> after the update. This is once.
> Since an updated bundle is not really updated until it is refreshed, when you
> refresh, bundle A's update is finalized by being refreshed, which causes it
> to stop and restart. This is twice.
> ...
> If bundle A was not being used, Felix would optimize this and do the refresh
> as part of the update, so it would only happen once.
> If File Install always refreshes after an update, it would be better to
> change it to first stop all bundles being updated, then update all bundles,
> then refresh, then restart all updated bundles. This way they would only
> stop/restart once."
> I am not sure if the behavior has changed in newer version of fileinstall or
> not. If not, this will be a good change to make.
