env","message":"Enhance service restart in functional env\n\nBugfix Icaf1bae8cb040b939f916a19ce026031ddb84af7 showed that restarting\na compute service in the functional env is unrealistic causing faults\nto slip through. During that bug fix only the minimal change was done\nin the functional env regarding compute service restart to reproduce\nthe reported fault. However the restart of the compute service could\nbe made even more realistic.\n\nThis patch simulates a compute service restart in the functional env\nby stopping the original compute service and starting a totally new\ncompute service for the same host and node. This way we can make sure\nthat we get a brand new ComputeManager in the new service and no\nstate can leak between the old and the new service.\n\nThis change revealed another shortcoming of the functional env.\nIn the real world the nova-compute service could be restarted without\nloosing any running servers on the compute host. But with the naive\nimplementation of this change the compute service is re-created. This\nmeans that a new ComputeManager is instantiated that loads a new\nFakeDriver instance as well. That new FakeDriver instance then reports\nan empty hypervisor. This behavior is not totally unrealistic as it\nsimulates such a compute host restart that cleans the hypervisor state\nas well (e.g. compute host redeployment). However this type of restart\nshows another bug in the code path that destroys and deallocates\nevacuated instance from the source host. Therefore this patch\nimplements the compute service restart in a way that simulates only a\nservice restart and not a full compute restart. A subsequent patch will\nadd a test that uses the clean hypervisor case to reproduces the\nrevealed bug.\n\nRelated-Bug: #1724172\n\nOn stable/stein:\n\nCloses-Bug: #1859766\n\nConflicts:\n    doc/notification_samples/libvirt-connect-error.json\n    nova/test.py\n    nova/tests/functional/libvirt/test_reshape.py\n    nova/tests/functional/test_servers.py\n\nNOTE(elod.illes): files conflicts details:\n* libvirt-connect-error.json:\n  File added only in Stein with libvirt.error notification\n  transformation patch I7d2287ce06d77c0afdef0ea8bdfb70f6c52d3c50\n* test.py:\n  Patches Iecf4dcf8e648c9191bf8846428683ec81812c026 (Remove patching\n  the mock lib) and Ibb8c12fb2799bb5ceb9e3d72a2b86dbb4f14451e (Use a\n  static resource tracker in compute manager) were not backported to\n  Rocky\n* test_reshape.py:\n  File added only in Stein in the frame of \u0027Handling Reshaped Provider\n  Trees\u0027 feature, with patch Ide797ebf7790d69042ae275ebec6ced3fa4787b6\n* test_servers.py:\n  Patch I7cbd5d9fb875ebf72995362e0b6693492ce32051 (Reject forced move\n  with nested source allocation) is not present in Rocky as it is part\n  of \u0027Nested Resource Providers - Allocation Candidates\u0027 implemented in\n  Stein\n\nChange-Id: I9d6cd6259659a35383c0c9c21db72a9434ba86b1\n(cherry picked from commit 2794748d9c58623045023f34c7793c58ce41447c)\n(cherry picked from commit b874c409c11b5d83508d2f0276a9a648f72192a4)\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/53a893f7c97e35de3e9ac26101827cdb43ed35cc"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/53a893f7c97e35de3e9ac26101827cdb43ed35cc"}]},"branch":"refs/heads/stable/rocky"}},"requirements":[],"submit_records":[],"submit_requirements":[]}
