There are no real changes, just moving files around. Sockets will be
used in the future to find available ports in cdc_stream. Therefore,
they need to be in common.
Fixes an issue with port forwarding when localhost on the remote
system maps to the IPV6 localhost. In that case the server would time
out on accept() since it creates an IPV4 socket, so the connection
is never established.
Also allows passing in port 0, so that it will auto-detect an
available port. This will be used in a future CL to remove the
necessity of running netstat/ss.
Build id is an optional unique identifier specified during cdc_rsync build via CDC_BUILD_VERSION definition.
If build id specified on both client and server components it will be used to check the version of server component instead of file size + modified time.
Makes ServerSocket multi-platform, mainly by working around some small
API differences. The code is largely the same, there should be no
differences on Linux.
Also moves WSAStartup() and WSACleanup() up to the Socket level as
static methods because it's used by both ClientSocket and ServerSocket,
and because it doesn't make sense to do that in the socket class as
that would prevent one from using several sockets.
The tools allow efficient and fast synchronization of large directory
trees from a Windows workstation to a Linux target machine.
cdc_rsync* support efficient copy of files by using content-defined
chunking (CDC) to identify chunks within files that can be reused.
asset_stream_manager + cdc_fuse_fs support efficient streaming of a
local directory to a remote virtual file system based on FUSE. It also
employs CDC to identify and reuse unchanged data chunks.
