[libvirt] [PATCH v2 0/4] Optimize mass closing of FDs on child spwaning

[libvirt] [PATCH 0/3] Optimize mass closing of FDs on child spwaning
by Michal Privoznik 15 Jul '19

15 Jul '19

If the limit for max opened files is way bigger than the default (1024), say 3 orders bigger then spawning a child through virCommand can be expensive because we iterate over ALL FDs within the limit and close them. There's no need to that since we can learn the list of opened FDs from /proc/self/fd/.

[libvirt] [PATCH] tests: don't assume "localhost" only resolves to 1/2 IPs

On Debian derived distros "localhost" can resolve to the normal "127.0.0.1" and "::1", but it can also resolve to "127.0.1.1" Rewrite the code so that it doesn't assume a fixed number of IPs.

Hello, The following two patches add a new bingding for virDomainInterfaceAddresses. While working on it I have found that the PHP7 version of the VIRT_ARRAY_INIT macro was causing segfaults which I have fixed in the first patch wheread the actual implementation of the binding is in the second one.
