BOINC Supervisor

This application implements enough of BOINC IPC to support running simple apps without real BOINC client.

For reference see in BOINC sources:

Preparing files from Rosetta

Prepare a destination directory for your files:
- Put absolute path to it in dest variable.
- Run mkdir -p $dest/{slots,projects}.
Copy Rosetta files:
- Save boinc directory path (probably /var/lib/boinc, if it's running as system daemon) as boinc variable.
- cp -r $boinc/projects/boinc.bakerlab.org_rosetta $dest/projects/
- Find pid (save as rosetta_pid) and a slot directory name (save as slot) of a running Rosetta process using lsof +d $boinc/slots/.
- cp -r $boinc/slots/$slot $dest/slots/
- Save the command line using ps -p $rosetta_pid -fww > $dest/slots/$slot/run.sh. Edit the file so it looks like
```
#!/bin/sh
exec ../../projects/boinc.bakerlab.org_rosetta/rosetta_4.20_x86_64-pc-linux-gnu [...]
```
- sed -i 's|<client_pid>[0-9]*</client_pid>|<client_pid>1</client_pid>|' $dest/slots/$slot/init_data.xml
- If you want to share the package safely with others:
```
for tag in user_name authenticator userid teamid hostid user_total_credit user_expavg_credit host_total_credit host_expavg_credit; do
    sed -i "s|<${tag}>.*</${tag}>|<${tag}></${tag}>|" $dest/slots/$slot/init_data.xml;
done
```

Build this as a static binary.
cp target/x86_64-unknown-linux-musl/release/boinc-supervisor $dest/slots/$slot/
docker run -v "${dest}:${boinc}" -ti --rm -u "$(id -u):$(id -g)" alpine sh Warning: it's important that the $boinc path inside container is the same as it was on host system.
Inside docker:
- Remember, that's it's a new shell, so you don't have your boinc and slot variables.
- cd $boinc/slots/$slot
- ./boinc-supervisor &
- ./run.sh

Download docker image

docker pull docker.pkg.github.com/golemfactory/boinc-supervisor/boinc-supervisor:latest

or build your own

cd docker
./build.sh

Run
```
docker run -d -v "${dest}:${boinc}" --rm -u "$(id -u):$(id -g)" boinc-supervisor "${boinc}/slots/${slot}/" ./run.sh
```
The first parameter is a path to slot directory. Entrypoint script will launch boinc-supervisor there. Next parameters will be used as a command and arguments to be launched there. In this example it's run.sh without arguments.
