...nded the summary-function to my.summary including SDev, in order to use it with tapply, which crashes in case of groups with no valid data. 2. is a similar problem. I use tapply with hist. On groups without valid data it crashes, like hist(as.numeric(c(NA))) returning Error in pretty(rx, n = nnb, min.n = 1) : x must be numeric hist(as.numeric(c(NA)),breaks=c(1,2)) works, as it does not use "pretty". I know these are very special cases, but unfortunately they kill the whole process. I can figure out some personal solution, but I hope for a professional one. Hope this is kind o...

I'm not sure exactly which version we're up to, but let's say it's version 4. I'm a lot happier with this version: - all filters have been reviewed and changed where I think that's necessary - can_extents is properly defined and implemented now - NBD protocol is followed - I believe it addresses all previous review points where possible The "only" thing

Since v1: - rework .can_cache to be tri-state, with default of no advertisement (ripple effect through other patches) - add a lot more patches in order to round out filter support And in the meantime, Rich pushed NBD_CMD_CACHE support into libnbd, so in theory we now have a way to test cache commands through the entire stack. Eric Blake (24): server: Internal hooks for implementing

This has already been pushed upstream. I am simply posting these here so we have a reference in the mailing list in case we find bugs later (as I'm sure we will - it's a complex patch series). Great thanks to Eric Blake for tireless review on this one. It also seems to have identified a few minor bugs in qemu along the way. Rich.

This is a cover letter to a series of patches being proposed in tandem to four different projects: - nbd: Document a new NBD_CMD_FLAG_FAST_ZERO command flag - qemu: Implement the flag for both clients and server - libnbd: Implement the flag for clients - nbdkit: Implement the flag for servers, including the nbd passthrough client If you want to test the patches together, I've pushed a
