Validated chunks are shared to other peers. Force check is now very simple since it just turns all chunks into "needs checking" mode and sums are asked to sources. Sources maintain a temporary cache of chunks. Since sums are requested sparsely, this should not affect the sources in terms of performance. We can still imagine precomputing and saving sha1 of chunks while hashing them. For backward compatibility reasons, the following has been setup *temporarily* in this version: - unvalidated chunks are still considered as already obtained, and are shared and saved - force check has been disabled - final file check is maintained - in case of file fail, the old checking mode will be used. All changes for next version are kept in the define 'USE_NEW_CHUNK_CHECKING_CODE' that will be made the default in a few weeks. At start, I expect most chunk to stya yellow during download, until most sources are able to provide chunk hashs. git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@5019 b45a01b8-16f6-495d-af2f-9b41ad6348cc
