[libvirt] [PATCH] Revert "spec: Bump minimum supported Fedora version to 29"
by Ján Tomko 20 Jun '19

20 Jun '19

This reverts commit 8a1179831b5edc0a3590489eda693914fc0ff94f. It bumped the version prematurely, before the EOL of Fedora 28. Morover, this arbitrary bump did not let us perform any cleanups in the specfile.

[libvirt] [PATCH] virNetworkGetDHCPLeases: fix docstring format

[libvirt] [PATCH RFC] test_driver: check that the domain is running in testDomainGetTime
by Ilias Stamatis 20 Jun '19

20 Jun '19

Signed-off-by: Ilias Stamatis <stamatis.iliass(a)gmail.com> --- Currently in the test driver in APIs that would normally require guest agents and similar we are just checking if the domain is active (using virDomainObjCheckActive). But a domain will be active even if stopped, so I would say that most of the time this is not sufficient since we really want to now that the domain is actually running, not that it's just active. So something like what I include in this patch is needed instead. I wonder if it would make sense to add a new function such as testDomainAgentAvailable inspired by the QEMU driver. So the check whether the domain is actually running or not could be done there. Also, in that case I'm not sure if calling both virDomainObjCheckActive and testDomainAgentAvailable is needed. I feel like calling the second one only is sufficient. However, in the QEMU driver always both are called. Should I go ahead with implementing the testDomainAgentAvailable function and search for all the places in the test driver that it should be used instead of virDomainObjCheckActive? src/test/test_driver.c | 20 ++++++++++++++++++-- 1 file changed, 18 insertions(+), 2 deletions(-) diff --git a/src/test/test_driver.c b/src/test/test_driver.c index 2a0ffbc6c5..8e5bd4e670 100755 --- a/src/test/test_driver.c +++ b/src/test/test_driver.c @@ -1984,17 +1984,33 @@ testDomainGetState(virDomainPtr domain, } static int -testDomainGetTime(virDomainPtr dom ATTRIBUTE_UNUSED, +testDomainGetTime(virDomainPtr dom, long long *seconds, unsigned int *nseconds, unsigned int flags) { + int ret = -1; + virDomainObjPtr vm = NULL; + virCheckFlags(0, -1); + if (!(vm = testDomObjFromDomain(dom))) + goto cleanup; + + if (virDomainObjGetState(vm, NULL) != VIR_DOMAIN_RUNNING) { + virReportError(VIR_ERR_OPERATION_INVALID, "%s", + _("domain is not running")); + goto cleanup; + } + *seconds = 627319920; *nseconds = 0; - return 0; + ret = 0; + + cleanup: + virDomainObjEndAPI(&vm); + return ret; } #define TEST_SAVE_MAGIC "TestGuestMagic" -- 2.22.0
