The CI will fail for OCaml <4.13 because some newer Stdlib functions are used, do we intend to support these? |
|
We previously discussed that the minimum OCaml version could be bumped. I'd suggest doing that in a PR of its own and checking the Ci passes there. 4.13 is probably ok mirage/ocaml-vhd#78 (comment) |

For efficiency it would be better to collect all strings in a list and do a String.concat or to use a Buffer value.

Switched to using a Buffer in the fixup commit.

Somehow missed that Frediano's tailcall assertions aren't actually tailcalls, so the CI fails: Dropping this commit altogether |

I've addressed the comments, and tested this. If the fixup looks good, I can squash it and we can merge this. |

Since call IDs are encoded in C as enum variants, the removal of Restrict created a hole that should be treated as an error. Oxenstored treats it as an Invalid variant, so follow that practice here as well. Signed-off-by: Andrii Sultanov <andrii.sultanov@cloud.com>
Also add Reset_watches call that has been added upstream - currently unimplemented. It needs to be present so as not to leave a hole in call IDs. Server implementation is a noop as well.

Adds the partial directory call to
client_unix. Server implementation is available in xapi-project/oxenstored#2, so wasn't attempted here.Also removes the deprecated Restrict call, and brings some minor improvements elsewhere.
Thanks to @freddy77 for working on this.
Changes were tested with the server implementation above, with the client coping well with large directories without having to utilize larger packets.
