[CRIU] Image cache/proxy TODO

[Rodrigo Bruno]

Hi,

last time I touched this code we had some zdtm tests failing.

Have you checked how many tests/issues still need to be fixed?

cheers,
rodrigo

> 1. Add articles for newly introduced actions and options.

> * https://criu.org/CLI/cmd/image-cache
> * https://criu.org/CLI/cmd/image-proxy

> 2. Make the UNIX sockets reside in work-dir.
> - The option -D|--images-dir should become optional. When --remote is used,
> CRIU should work purely on the work-dir and not generate anything in the
> images-dir.
>
> 3. Tune up the image_cache and image_proxy commands to accept the
> --status-fd
> and --pidfile options.
>
> 4. Fix local connections not to generate per-image threads.
> - I believe that this one is already done.
>
> 5. No strings in protocol. Now the hard-coded "RESTORE_FINISH" string
> (and DUMP_FINISHED one) is used to terminate the communication.
> Need to tune up the protobuf objects to send boolean (or integer) EOF
> sign rather that the string.
>
> 6. Check how proxy/cache works with incremental dumps.
>
> 7. Add support for cache/proxy into go-phaul code.
>
> Is there anything else?
