Hi, i'm running CentOS 6.0 on my server and installed mrtg from the rpm-package mrtg-2.16.2 . I also installed the depending packages perl-IO-Socket-INET6 perl-Socket6 .... mrtg works fine with IPV4-Addresses. When i specify a Target by IPV6-Address (or hostname resolving to a V6-address) mrtg fails. Here i have a small sample-config for V4 which is working: LogDir: /tmp ThreshDir: /tmp

Drop the SET designation, so that we can reuse these states for OPT_LIST_META_CONTEXT in the next patch. --- generator/Makefile.am | 4 +-- generator/state_machine.ml | 6 ++--- ...t.c => states-newstyle-opt-meta-context.c} | 26 +++++++++---------- .../states-newstyle-opt-structured-reply.c | 4 +-- generator/states-newstyle.c

I'm posting this now, as I'm at the end of a workday and I got things working for manual experimentation. Still to do: - write interop tests for qemu-nbd and nbdkit (including my proposed patch addition of qemu-nbd -A to show qemu:allocation-depth) - figure out if we can make 'nbdinfo --map' use the new API to automatically select all contexts advertised by the server Eric Blake

Most of the states were calling SET_NEXT_STATE(%.DEAD) then using return -1 on error, to reflect the fact that they had also called set_error() and wanted the caller to notice the failure. Unfortunately, the state machine engine refuses to run the entry code of the next state when the current state returned -1, which meant the DEAD state entry code never runs. A concrete example of the problems

This isn't quite finished because not all of the tests or examples have been updated, but it demonstrates an idea: Should we forget about the concept of having multiple connections managed under a single handle? In this patch there is a single ‘struct nbd_handle *’ which manages a single state machine and connection (and therefore no nbd_connection). To connect to a multi-conn server you must

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.
