This makes sense when in\na traditional nova-compute use-case, where the host \u003d\u003d the hypervisor.\nHowever, in drivers such as Ironic, a single compute service manages\nmultiple hypervisors. This means that any updates to any hypervisor will\nlock the compute process and prevent it from making updates to another\nhypervisor.\n\nCombined with behavior such as the update_available_resource periodic\ntask, which runs every minute by default and necessarily locks the\ncompute host during inspection, the compute process experiences a severe\nslowdown from the user\u0027s point of view, and instance builds can get\nstuck waiting for a claim, up to and exceeding an hour in some\ndeployments.\n\nThis changes the lock behavior to lock on the \"nodename\" (the hypervisor\nhostname) instead of having a single lock for every operation. This\npreserves the isolation of changes within a single hypervisor, but\nallows multiple different hypervisors to be updated without locking\neach other. To accomplish this, the synchronized decorator cannot be\nused, as function arguments are needed to compute the lock name.\nInstead, the \"lock\" mechanism inside oslo.lockutils, which implements a\ncontext manager, is used to gate execution of the business logic.\n\nChange-Id: I05cef73aa71c97a1fa0f3dee0c28b2a2b00b97d6\nRelated-Bug: #1864122\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/c1136ec63c7df564316304e01212b6c1835e8ca5"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/c1136ec63c7df564316304e01212b6c1835e8ca5"}]},"branch":"refs/heads/master"}},"requirements":[],"submit_records":[],"submit_requirements":[]}
