with a\nplan to do lots of interoperability testing (including validation of\nbehavior against a server that sends more than one chunk for a read),\nand with any resulting bug fixes trying to land as soon as possible\nduring the freeze.\n\nI'm also a bit disappointed that iotest 83 is more verbose. I'll post a\nfollow RFC that undoes the verbosity regression, as evidence that we\nshould probably be tracing things instead; such a cleanup would count\nas a bug fix, even if my pull request includes this series as-is.\n\n001/12:[----] [--] 'nbd: Include error names in trace messages'\n002/12:[----] [--] 'nbd: Move nbd_errno_to_system_errno() to public header'\n003/12:[----] [--] 'nbd: Expose constants and structs for structured read'\n004/12:[----] [--] 'nbd/server: Report error for write to read-only export'\n005/12:[down] 'nbd/server: Simplify nbd_negotiate_options loop'\n006/12:[0066] [FC] 'nbd/server: Refactor zero-length option check'\n007/12:[0007] [FC] 'nbd: Minimal structured read for server'\n008/12:[----] [--] 'nbd/server: Include human-readable message in structured errors'\n009/12:[0004] [FC] 'nbd/client: refactor nbd_receive_starttls'\n010/12:[----] [--] 'nbd/client: prepare nbd_receive_reply for structured reply'\n011/12:[----] [--] 'nbd: Move nbd_read() to common header'\n012/12:[0055] [FC] 'nbd: Minimal structured read for client'\n\nEric Blake (8):\n nbd: Include error names in trace messages\n nbd: Move nbd_errno_to_system_errno() to public header\n nbd: Expose constants and structs for structured read\n nbd/server: Report error for write to read-only export\n nbd/server: Simplify nbd_negotiate_options loop\n nbd/server: Refactor zero-length option check\n nbd/server: Include human-readable message in structured errors\n nbd: Move nbd_read() to common header\n\nVladimir Sementsov-Ogievskiy (4):\n nbd: Minimal structured read for server\n nbd/client: refactor nbd_receive_starttls\n nbd/client: prepare nbd_receive_reply for structured reply\n nbd: Minimal structured read for client\n\n block/nbd-client.h | 1 +\n include/block/nbd.h | 106 +++++++++-\n nbd/nbd-internal.h | 23 +--\n block/nbd-client.c | 492 ++++++++++++++++++++++++++++++++++++++++++---\n nbd/client.c | 217 +++++++++++++-------\n nbd/common.c | 84 ++++++++\n nbd/server.c | 209 ++++++++++++++-----\n nbd/trace-events | 15 +-\n tests/qemu-iotests/083.out | 15 ++\n 9 files changed, 968 insertions(+), 194 deletions(-)" }
