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 support for local syncs of files and folders on the same Windows
machine, e.g. cdc_rsync C:\source C:\dest. The two main changes are
- Skip the check whether the port is available remotely with PortManager.
- Do not deploy cdc_rsync_server.
- Run cdc_rsync_server directly, not through an SSH tunnel.
The current implementation is not optimal as it starts
cdc_rsync_server as a separate process and communicates to it via a
TCP port.
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
So far, errors from the remote netstat process would only be logged in
the asset stream service, for instance when SSH auth failed. However,
the errors were not shown to the client, and that's the most important
thing.
Also adds some feedback to cdc_stream in case of success.
* Remove dependencies of cdc_sync from GGP
Allows overriding the SSH and SCP commands via command line flags.
Hence, strict host checking, SSH config etc. can be removed since it
is passed in by command line flags for GGP. Also deploys
cdc_rsync_server to ~/.cache/cdc_file_transfer/ and creates that dir
if it does not exist.
* Tweak RemoteUtil
Replaces localhost: by //./ in the workaround for scp since localhost:
had two disadvantages: 1) It required 2 gnubby touches for gLinux and
2) it didn't work for ggp. //./ works for both. Also tweaks quoting,
which didn't quite work for ggp.
* Don't check remote ports in cdc_rsync
Turns off checking remote ports in PortManager. In the future, the
server should return available ports after failing to connect to the
provided port.
Since now the first remote connection is running cdc_rsync_server,
the timeout check has to be done when running that process.
* Remove now-unused kInstancePickerNotAvailableInQuietMode enum
* Add more details to the readme
* [cdc_rsync] Accept [user@]host:destination
Removes the --ip command line argument and assumes user/host are
passed in along with the destination, so it works in the same way as
other popular tools.
* [ggp_rsync] Combine server deploy commands
Combines two chmod and one mv command into one ssh command. This makes
deploy a bit quicker, especially if each ssh command involves touching
your gnubby.
* Remove GGP specific stuff from VS build commands
* [cdc_rsync] Get rid of cdc_rsync.dll
Compile the CDC RSync client as a static library instead. This removes
quite a bit of boiler plate and makes string handling easier since
we can now pass std::strings instead of const chars.
Also fixes an issue where we were sometimes trying to assign nullptr
to std::strings, which is forbidden.
* Allow specifying ssh/scp commands with env vars
* Rename GgpRsync* to CdcRsync*
* Merge ggp_rsync_cli into ggp_rsync
* [cdc_rsync] Refactor cdc_rsync.cc/h
Merges cdc_rsync.cc/h with main.cc and CdcRsyncClient since code is
closer to where it's being used and should be more readable.
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.
