From c8d44e634c381572975f670cd91af6fae01d99c6 Mon Sep 17 00:00:00 2001 From: Eric Blake Date: Fri, 20 Jan 2012 11:43:28 -0700 Subject: API: make declaration of _LAST enum values conditional Although this is a public API break, it only affects users that were compiling against *_LAST values, and can be trivially worked around without impacting compilation against older headers, by the user defining VIR_ENUM_SENTINELS before using libvirt.h. It is not an ABI break, since enum values do not appear as .so entry points. Meanwhile, it prevents users from using non-stable enum values without explicitly acknowledging the risk of doing so. See this list discussion: https://www.redhat.com/archives/libvir-list/2012-January/msg00804.html * include/libvirt/libvirt.h.in: Hide all sentinels behind LIBVIRT_ENUM_SENTINELS, and add missing sentinels. * src/internal.h (VIR_DEPRECATED): Allow inclusion after libvirt.h. (LIBVIRT_ENUM_SENTINELS): Expose sentinels internally. * daemon/libvirtd.h: Use the sentinels. * src/remote/remote_protocol.x (includes): Don't expose sentinels. * python/generator.py (enum): Likewise. * tests/cputest.c (cpuTestCompResStr): Silence compiler warning. * tools/virsh.c (vshDomainStateReasonToString) (vshDomainControlStateToString): Likewise. --- generator.py | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'generator.py') diff --git a/generator.py b/generator.py index 6fee3a4..de635dc 100755 --- a/generator.py +++ b/generator.py @@ -205,7 +205,8 @@ def enum(type, name, value): value = 1 elif value == 'VIR_DOMAIN_AFFECT_CONFIG': value = 2 - enums[type][name] = value + if name[-5:] != '_LAST': + enums[type][name] = value def qemu_enum(type, name, value): if not qemu_enums.has_key(type): -- cgit
