Optimize File Install
---------------------
Key: FELIX-939
URL: https://issues.apache.org/jira/browse/FELIX-939
Project: Felix
Issue Type: Improvement
Environment: generic
Reporter: Sahoo
File Install has a dedicated thread for every directory. That thread wakes up
periodically and then does the following:
1. Iterates over all the bundles by calling context.getBundles
2. Finds out all bundles which belong to watchedDir. It starts them.
3. Finds if there is any new jar file in the watchedDir. It installs them.
4. Finds out if any jar has been deleted from watcheDir. It uninstalls
corresponding bundles.
5. Finds out if any jar has been modified. It updates the corresponding bundles.
I think there is some scope for optimization here. Especially step #2 seems
redundant if there has been change in the file system. More over, if out of all
the bundles in the system, only a few belong to watchedDir, then the current
implementation performs poorly.
