Improves ServerArch so that it can detect the remote architecture by
running uname and checking %PROCESSOR_ARCHITECTURE%. So far, only
x64 Linux and x64 Windows are supported, but in the future it is easy
to add support for others, e.g. aarch64, as well.
Before the detection is run, the remote architecture is guessed first
based on the destination. For instance, if the destination directory
starts with "C:\", it pretty much means Windows. If cdc_rsync_server
exists and runs fine, there's no need for detection.
Since also PortManager depends on the remote architecture, it has to
be adjusted as well. So far, PortManager assumeed that "local" means
Windows and "remote" means Linux. This is no longer the case for
syncing to Windows devices, so this CL adds the necessary abstractions
to PortManager.
Also refactors ArchType into a separate class in common, since it is
used now from several places. It is also expanded to handle future
changes that add support for different processor architectures, e.g.
aarch64.
Adds a flag to set the SSH forwarding port or port range used for
'cdc_stream start-service' and 'cdc_rsync'.
If a single number is passed, e.g. --forward-port 12345, then this
port is used without checking availability of local and remote ports.
If the port is taken, this results in an error when trying to connect.
Note that this restricts the number of connections that stream can
make to one.
If a range is passed, e.g. --forward-port 45000-46000, the tools
search for available ports locally and remotely in that range. This is
more robust, but a bit slower due to the extra overhead.
Optimizes port_manager_win as it was very slow for a large port range.
It's still not optimal, but the time needed to scan 30k ports is
<< 1 seconds now.
Fixes#12
* [cdc_stream] Fix issues found in tests
Fixes a couple of issues found by integration testing:
- Unicode command line args in cdc_stream show up as question marks.
- Log is still named assets_stream_manager instead of cdc_stream.
- An error message contains stadia_assets_stream_manager_v3.exe.
- mount_dir was not the last arg as required by FUSE
- Promoted cache cleanup logs to INFO level since they're important
for the proper workings of the system.
- Asset streaming cache dir is still %APPDATA%\GGP\asset_streaming.
