[libvirt] [RFC 0/2] util: introduce timeout mode in virCommandRun/Async and virKModLoad
by Shi Lei 13 Aug '18

13 Aug '18

Hi, everyone! It's possible that the running-time of a command is long than its caller expected. Perhaps, it's useful to provide timeout mode for virCommandRun or virCommandRunAsync + virCommandWait. And The caller can restrict the running time of the command if necessary. I introduce a new function virCommandSetTimeout for that. And then, virKModLoad will get a default timeout of 3 seconds. I hope it could solve the problem of "strange delay" as John mentioned. Thanks!

[libvirt] [PATCH] src: Move DLOPEN_LIBS to libraries introducing the dependency
by Michal Privoznik 13 Aug '18

13 Aug '18

There are few places where dlopen() is called. This call means we have to link with DLOPEN_LIBS. However, instead of having each final, installable library linking with it, move the directive to the source that introduced the dependency.
