This doesn't include Eric's new APIs, but if you push those then I can rebase this one on top. Rich.

v1 was here: https://listman.redhat.com/archives/libguestfs/2022-October/030216.html Since then, I've incorporated changes based on Rich's feedback: swap order of patches 2 and 3 less change in patch 1 (including no unsafe eval(%s) for --uri) in patch 2, include -c in list of snippets to store, and use dict of lambdas to map back to the desired action Eric Blake (3): nbdsh:

Since v2: - rebase to Rich's new API calls - more refactoring in patch 1 (retitled) - new patches 3 and 4 - fix data corruption in patch 6 (was 4) - more tweaks to the reproducer example (including using new API from 3) Eric Blake (7): lib: Refactor command_common() to do more common work commands: Allow for a command queue commands: Expose FIFO ordering of server completions

I still need to wire in the use of *_notify functions into nbdkit to prove whether it makes the code any faster or easier to maintain, but at least the added example shows one good use case for the new API. Eric Blake (6): api: Add nbd_aio_in_flight generator: Allow DEAD state actions to run generator: Allow Int64 in callbacks states: Prepare for aio notify callback api: Add new
