[Framework] Bundle cache implementation could do a better job of avoiding disk
access
-------------------------------------------------------------------------------------
Key: FELIX-2619
URL: https://issues.apache.org/jira/browse/FELIX-2619
Project: Felix
Issue Type: Improvement
Components: Framework
Affects Versions: framework-3.0.3
Reporter: Richard S. Hall
Assignee: Richard S. Hall
Priority: Minor
Fix For: framework-3.2.0
The bundle archive implementation tries to limit disk accesses by only reading
variables from the disk the first time and the caching the result. In some
cases, though, it is not too smart. Like in BundleArchive.getRefreshCount()
where it checks if a file exists and if not then simply returns the default
value. This means all default values will incur a disk access to check for file
existence. It should cache the default value after first read too, to avoid
future disk accesses.
