Apache Celix is a framework for C and C++14 to develop dynamic modular software applications using component and in-process service-oriented programming.
This PR implements basic support for uncompressed bundle.
The approach is fairly straightforward: when installing an uncompressed bundle, we create a symbolic link to the uncompressed bundle as the archive->resourceCacheRoot.
This way, all existing mechanisms (bundle target, config.properties, etc) work as before, provided that the zip bundle is unzipped into the bundle path with the same name as the zip file.
Whether zip/uncompressed form is preferred is left to our user as a deployment issue, thus out the scope of this PR.
Though the required modification is minimum, there are several corner cases worth noting:
Use the last modification time of the bundle archive cache directory rather than that of the manifest. These two timestamps are different for uncompressed bundle, which leads to unnecessary disk write.
Deleting uncompressed bundle unintentionally will lead to dangling links in bundle cache, which celix_utils_deleteDirectory can not deal with.
One goal of uncompressed bundle support is to improve startup speed. Unnecessary syncs of async bundle operations are removed.
