[libvirt] [PATCH 00/21] tests: qemuxml2argv: support optional arguments

Right now in qemuxml2argv we have a proliferation of DO_*TEST* macros. They essentially fill in data in the testInfo struct and invoke the test function. There's several bits of data that we want to specify for a small subset of tests: flags, parseFlags, migrateFrom/migrateFd, gic. The base macros need to handle these in their argument lists, and we provide many convenience macros that fill in default values for the less common parameters. Any time we want to add a new bit of data though, the base macros are extended, and every caller of those needs to be adjusted, and we are faced with the question of whether to extend the combinatorial explosion of convenience macros which have only a subset of options exposed. This series adds a testInfoSetArgs which uses va_args to make these mandatory parameters optional. The general format is: DO_TEST_FULL(... ARG_FOO, foovalue, ARG_BAR, barvalue, ...) Specifically, one of the migrate tests went from: DO_TEST_FULL("restore-v2", "exec:cat", 7, 0, 0, GIC_NONE, NONE); to: DO_TEST_FULL("restore-v2", ARG_MIGRATE_FROM, "exec:cat", ARG_MIGRATE_FD, 7, ARG_QEMU_CAPS, NONE); Which may not seem directly compelling, but adding new testInfo fields will be much easier. This will also be a base for a later series to share the VIR_TEST_CAPS infrastructure with qemuxml2xmltest Cole Robinson (21): qemu: add virQEMUCapsSetVList tests: qemuxml2argv: add testInfoSetArgs tests: qemuxml2argv: add va_arg enum handling tests: qemuxml2argv: push ARG_QEMU_CAPS to callers tests: qemuxml2argv: break apart testInitQEMUCaps tests: qemuxml2argv: handle gic with vaargs tests: qemuxml2argv: handle migrate* with varargs tests: qemuxml2argv: handle flags with varargs tests: qemuxml2argv: handle parseFlags with varargs tests: qemuxml2argv: remove DO_TEST_PARSE_FLAGS_ERROR tests: qemuxml2argv: remove unused DO_TEST_CAPS* macros tests: qemuxml2argv: add a comment separating DO_TEST* macros tests: qemuxml2argv: remove unused CAPS migrateFrom tests: qemuxml2argv: use varargs for CAPS flags tests: qemuxml2argv: remove full testInfo initialization tests: qemuxml2argv: centralize CAPS suffix building tests: qemuxml2argv: build capsfile in DO_TEST_CAPS_INTERNAL tests: qemuxml2argv: add testInfoClear tests: qemuxml2argv: move DO_TEST qemuCaps init tests: qemuxml2argv: move DO_CAPS_TEST* qemuCaps init tests: qemuxml2argv: add TEST_INTERNAL src/qemu/qemu_capabilities.c | 14 +- src/qemu/qemu_capabilities.h | 2 + tests/qemuxml2argvtest.c | 273 +++++++++++++++++++++++------------ 3 files changed, 193 insertions(+), 96 deletions(-) -- 2.20.1
