Detailed Description

This file is part of the CernVM File System.

This file is part of the CernVM File System.

The SyncMediator is an intermediate layer between the UnionSync implementation and the CatalogManager. It's main responsibility is to unwind file system intrinsics as deleting all files in a deleted directory. Furthermore newly created directories are recursed and all included files are added as a whole (performance improvement).

Furthermore it keeps track of hard link relations. As we cannot store the transient inode of the union file system in cvmfs, we just keep track of hard link relations itself. Inodes will be assigned at run time of the CVMFS client taking these relations into account.

Another responsibility of this class is the creation and destruction of nested catalogs. If a .cvmfscatalog magic file is encountered, either on delete or add, it will be treated as nested catalog change.

New and modified files are piped to external processes for hashing and compression. Results come back in a pipe.
