Re: [Libguestfs] [PATCH nbdkit v3 1/3] filters: Implement next_ops .reopen call.

This is intended for use by the forthcoming retry filter to close and reopen the backend chain. It is handled entirely by server/backend.c as no cooperation is needed with the plugin. Note the explicit readonly parameter: An alternative would be to store the previous readonly setting in the b_conn_handle struct. However passing it explicitly allows the retry filter to retry as readonly, which might be useful. This design does however require any filter which might call .reopen to save the original readonly parameter from the .open call. --- include/nbdkit-filter.h | 6 ++++++ server/backend.c | 12 ++++++++++++ server/filters.c | 8 ++++++++ server/internal.h | 4 ++++ 4 files changed, 30 insertions(+)
