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.
libvirt Python Bindings README
==============================
Most of the libvirt python binding code is automatically generated
using the script generator.py, and the API description from
docs/libvirt-api.xml
Manually written files:
- libvirt-override.c: methods where the C binding needs to be hand crafted
- libvirt-override.py: global methods where the C and python bindings have different args
- libvirt-override-api.xml: methods where the auto-extracted API docs are not
suitable for python auto-generator. Overriding this if the method is going
into libvirt-override.c, but we still want auto-generated libvirt-override.py
- libvirt-override-virConnect.py: virConnect class methods
- typewrappers.h,.c: Python object wrappers for each libvirt C object
Auto-generated files:
- libvirt.py: The main python binding. Comprises auto-generated code, along
with contents from libvirt-override.py and libvirt-override-virConnect.py
- libvirt.c, libvirt.h: The C glue layer for the python binding. Comprises
auto-generated code, along with libvirt-override.c
- libvirt-export.c: List of auto-generated C methods, included into
the libvirt-override.c method table
