[libvirt] [PATCH] build: Create needed folders without dependency tracking
by Martin Kletzander 30 Nov '15

30 Nov '15

The parameter --disable-dependency-tracking is supposed to speed up one-time build due to the fact that it disables some dependency extractors that, apparently, take longer time to execute. That is a problem for code that is generated into builddir (especially some specific subdirectory) because the directory it should be installed to does not exists in VPATH and without the dependency tracking is not created. Generating such file hence fails with -ENOENT. In order to keep generating files into builddir instead of srcdir, we must create the directory ourselves. This should finally fix the problem that is being fixed multiple times since its introduction in commit a9fe62037214 and let us continue with cleaning those parts of Makefiles that depend on generating files into the srcdir rather than builddir as it should be.

[libvirt] [PATCH] guest-agent-socket: don't generate default path to config XML
by Pavel Hrdina 30 Nov '15

30 Nov '15

While we started using for all unix sockets as default one common directory based on a guest name it introduced several issues, for example with renaming the guest or cloning it. In general it's not entirely bad, but in this case it would be best to hide the auto-generated socket path from user and don't export it in the config XML.

[libvirt] [PATCH v2] conf: Split virDomainObjList into a separate file
by Michal Privoznik 30 Nov '15

30 Nov '15

Our domain_conf.* files are big enough. Not only they contain XML parsing code, but they served as a storage of all functions whose name is virDomain prefixed. This is just wrong as it gathers not related functions (and modules) into one big file which is then harder to maintain. Split virDomainObjList module into a separate file called virdomainobjlist.[ch].
