[libvirt] [PATCH] qemu: capabilities: Move comments separating groups of capabilities
by Peter Krempa 21 Jun '17

21 Jun '17

Similarly to how we specify the groups of 5 capabilities in the header file move the labels to separate line also for the VIR_ENUM_IMPL part. This simplifies rebase conflict resolution in the capability file since only lines have to be shuffled around, but they don't need to be edited. --- src/qemu/qemu_capabilities.c | 159 ++++++++++++++++++++++++++++--------------- 1 file changed, 106 insertions(+), 53 deletions(-) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index a9171893e..61c9a1066 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -61,319 +61,372 @@ VIR_LOG_INIT("qemu.qemu_capabilities"); * daemon restarts */ VIR_ENUM_IMPL(virQEMUCaps, QEMU_CAPS_LAST, -

[libvirt] [PATCH v2] util: fix locale problem with virStrToDouble().
by Julio Faracco 21 Jun '17

21 Jun '17

This commit fixes a locale problem with locales that use comma as a mantissa separator. Example: 12.34 en_US = 12,34 pt_BR. Since strtod() is a non-safe function, virStrToDouble() will have problems to parse double numbers from kernel settings and other double numbers from static files (XMLs, JSONs, etc).
