With musl-1.2.3: I get the following macros defined (from $builddir/meson-config.h): #define WITH_LSTAT 1 #define WITH_LSTAT64 1 #define WITH_LSTAT_DECL 1 #define WITH_STAT 1 #define WITH_STAT64 1 #define WITH_STAT_DECL 1 #define WITH___LXSTAT 1 #define WITH___LXSTAT64 1 #define WITH___XSTAT 1 #define WITH___XSTAT64 1 which in turn means the virmockstathelpers.c ends up defining: MOCK_STAT64 MOCK_LSTAT64 But with musl-1.2.4 everything changes and the set of defined macros gets simplified to: #define WITH_LSTAT 1 #define WITH_LSTAT_DECL 1 #define WITH_STAT 1 #define WITH_STAT_DECL 1 #define WITH___LXSTAT 1 #define WITH___XSTAT 1 which results in no MOCK_* macros defined in virmockstathelpers.c, i.e. no stat() mocking, nada. The reason for this simplification are these musl commits [1][2] which removed all 64 bit aliases. And that's not what our logic for deciding what flavor of stat() to mock counted with. Nevertheless, we do build with Alpine Linux in our CI, so how come we don't see this problem there? Well, simply because Alpine Linux maintainers decided to revert the commits [3][4]. But on distributions that use vanilla musl, this problem can be seen easily. 1: https://git.musl-libc.org/cgit/musl/commit/?id=246f1c811448f37a44b41cd8df8d0ef9736d95f4 2: https://git.musl-libc.org/cgit/musl/commit/?id=25e6fee27f4a293728dd15b659170e7b9c7db9bc 3: https://git.alpinelinux.org/aports/commit/main/musl?id=6a5563fbb45b3d9d60678d7bbf60dbb312a2d481 4: https://git.alpinelinux.org/aports/commit/main/musl?id=a089bd852f8983623fa85e0f5755a3e25bf53c72 Resolves: https://bugs.gentoo.org/906167 Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Martin Kletzander <mkletzan@redhat.com>
Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
