Hi list, I have been working on a custom git server where the sha values required to respond to a ls-refs command can occasionally be expensive to compute. It would be a great improvement of user experience if it was possible to show progress to the user while this is happening. I was hoping that this could be solved by using the already existing sideband-all capability, but unfortunately it seems that even with sideband-all the sideband is not available during ls-refs. So my plan would be to start working on a patch to add sideband support to ls-refs, unless there is some other protocol feature that I have overlooked and that would enable my use case. Any pointers to either alternative solutions and/or hints to potential pitfalls in the implementation of my suggestion would be greatly appreciated. Best regards, Christian Schilling
