Arik Hadas has submitted this change and it was merged. Change subject: core: introduce RunVmCommand#RunVmFlow ...................................................................... core: introduce RunVmCommand#RunVmFlow RunVmCommand is a complicated command since it contains several different flows: - Resume paused VM - Resume hibernated VM - Create snapshot and then run the VM for running stateless VMs - Remove snapshot in case the VM already contains stateless snapshot - Run VM in all other cases This patch introduces an enumeration that represents the different flows. The benefits of using an enum: - It replaces local flags that indicates the different flows (mResume, isFailedStatelessSnapshot) - It makes the code more structured - It can be used to eliminate unnecessary operations in certain flows more easily. In this patch, I used it in order to prevent initialize the VM object in flows where we don't really need it - In the context of the planned enhancements for RunVmCommand, it allows us to query the flow from outside of the command Change-Id: I2a3f062323c4246b45757d3062478c0109d70708 Signed-off-by: Arik Hadas <ahadas(a)redhat.com&gt; --- M backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/RunVmCommand.java M backend/manager/modules/bll/src/main/java/org/ovirt/engine/core/bll/RunVmOnceCommand.java M backend/manager/modules/bll/src/test/java/org/ovirt/engine/core/bll/RunVmCommandTest.java 3 files changed, 200 insertions(+), 46 deletions(-) Approvals: Arik Hadas: Verified; Looks good to me, approved -- To view, visit http://gerrit.ovirt.org/22663 To unsubscribe, visit http://gerrit.ovirt.org/settings Gerrit-MessageType: merged Gerrit-Change-Id: I2a3f062323c4246b45757d3062478c0109d70708 Gerrit-PatchSet: 23 Gerrit-Project: ovirt-engine Gerrit-Branch: master Gerrit-Owner: Arik Hadas <ahadas(a)redhat.com&gt; Gerrit-Reviewer: Allon Mureinik <amureini(a)redhat.com&gt; Gerrit-Reviewer: Arik Hadas <ahadas(a)redhat.com&gt; Gerrit-Reviewer: Omer Frenkel <ofrenkel(a)redhat.com&gt; Gerrit-Reviewer: Roy Golan <rgolan(a)redhat.com&gt; Gerrit-Reviewer: automation(a)ovirt.org Gerrit-Reviewer: oVirt Jenkins CI Server
