xml: output memory unit for clarity Make it obvious to 'dumpxml' readers what unit we are using, since our default of KiB for memory (1024) differs from qemu's default of MiB; and differs from our use of bytes for storage. Tests were updated via: $ find tests/*data tests/*out -name '*.xml' | \ xargs sed -i 's/<\(memory\|currentMemory\|hard_limit\|soft_limit\|min_guarantee\|swap_hard_limit\)>/<\1 unit='"'KiB'>/" $ find tests/*data tests/*out -name '*.xml' | \ xargs sed -i 's/<\(capacity\|allocation\|available\)>/<\1 unit='"'bytes'>/" followed by a few fixes for the stragglers. Note that with this patch, the RNG for <memory> still forbids validation of anything except unit='KiB', since the code silently ignores the attribute; a later patch will expand <memory> to allow scaled input in the code and update the RNG to match. * docs/schemas/basictypes.rng (unit): Add 'bytes'. (scaledInteger): New define. * docs/schemas/storagevol.rng (sizing): Use it. * docs/schemas/storagepool.rng (sizing): Likewise. * docs/schemas/domaincommon.rng (memoryKBElement): New define; use for memory elements. * src/conf/storage_conf.c (virStoragePoolDefFormat) (virStorageVolDefFormat): Likewise. * src/conf/domain_conf.h (_virDomainDef): Document unit used internally. * src/conf/storage_conf.h (_virStoragePoolDef, _virStorageVolDef): Likewise. * tests/*data/*.xml: Update all tests. * tests/*out/*.xml: Likewise. * tests/define-dev-segfault: Likewise. * tests/openvzutilstest.c (testReadNetworkConf): Likewise. * tests/qemuargv2xmltest.c (blankProblemElements): Likewise.

Introduce new OOM testing support The previous OOM testing support would re-run the entire "main" method each iteration, failing a different malloc each time. When a test suite has 'n' allocations, the number of repeats requires is (n * (n + 1) ) / 2. This gets very large, very quickly. This new OOM testing support instead integrates at the virtTestRun level, so each individual test case gets repeated, instead of the entire test suite. This means the values of 'n' are orders of magnitude smaller. The simple usage is $ VIR_TEST_OOM=1 ./qemuxml2argvtest ... 29) QEMU XML-2-ARGV clock-utc ... OK Test OOM for nalloc=36 .................................... OK 30) QEMU XML-2-ARGV clock-localtime ... OK Test OOM for nalloc=36 .................................... OK 31) QEMU XML-2-ARGV clock-france ... OK Test OOM for nalloc=38 ...................................... OK ... the second lines reports how many mallocs have to be failed, and thus how many repeats of the test will be run. If it crashes, then running under valgrind will often show the problem $ VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest When debugging problems it is also helpful to select an individual test case $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest When things get really tricky, it is possible to request that just specific allocs are failed. eg to fail allocs 5 -> 12, use $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-12 ../run valgrind ./qemuxml2argvtest In the worse case, you might want to know the stack trace of the alloc which was failed then VIR_TEST_OOM_TRACE can be set. If it is set to 1 then it will only print if it thinks a mistake happened. This is often not reliable, so setting it to 2 will make it print the stack trace for every alloc that is failed. $ VIR_TEST_OOM_TRACE=2 VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-5 ../run valgrind ./qemuxml2argvtest 30) QEMU XML-2-ARGV clock-localtime ...

tests: simplify common setup A few of the tests were missing basic sanity checks, while most of them were doing copy-and-paste initialization (in fact, some of them pasted the argc > 1 check more than once!). It's much nicer to do things in one common place, and minimizes the size of the next patch that fixes getcwd usage. * tests/testutils.h (EXIT_AM_HARDFAIL): New define. (progname, abs_srcdir): Define for all tests.
