If we plan to fix, bz [1] is another candidate that has to be targeted for 4.0.
Gluster's XDR does not conform to RFC spec
Gluster's XDR does not conform to RFC spec
Description of problem: In an attempt to generate bindings to Gluster's XDR with Rust I've run into a few problems. It appears the XDR .x spec files are using keywords that are not legal according to the RFC spec https://tools.ietf.org/html/rfc4506.html. This hinders language adoption of Gluster. If anyone would like to produce pure language bindings this prevents them from succeeding. Indeed I think community adoption of Gluster would benefit from having a wider range of XDR bindings on which to build tooling. Some of the problems I've encountered: 1. RFC4506 doesn't define "long" as a basic type in .x files; unsigned hyper is its 64 bit unsigned type. 2. Also unsigned char uuid[16] not defined Possibly other problems that I haven't gotten to yet as the parser moves through the files. Version-Release number of selected component (if applicable): How reproducible: Always reproducible.

Hi All,
Below are the proposed protocol changes (ie, XDR changes on the wire) we are thinking for Gluster 4.0.
Poornima and I were discussing if we can include volume uuid as part of Handshake protocol between protocol/client and protocol/server so that clients do not re-connect if the volume was deleted and recreated with the same name, eliminating potential issues at upper layers [1].
We haven't looked into details, but the idea is to have glusterd2 send volume uuid as part of GETSPEC request to clients & brick processes which shall be used by protocol/client & protocol/server (may be along with vol name as well) during HNDSK_SETVOLUME.
Poornima/Ram,
Please add if I missed out anything.
Thanks,
Soumya
