With recent migrate QAPI changes, enabling the direct use of the 'channels' argument to avoid redundant URI string parsing is achieved. To ensure backward compatibility, both 'uri' and 'channels' are kept as optional parameters in migration QMP commands. However, they are mutually exhaustive, requiring at least one for a successful migration connection. This patchset adds qtests to validate 'uri' and 'channels' arguments' mututally exhaustive behaviour. Additionally, all migration qtests fail to employ 'channel' as the primary method for validating migration QAPIs. This patchset also adds test to enforce only use of 'channel' argument as the initial entry point for migration QAPIs. Patch Summary: ------------- Patch 1-2: --------- Introduce 'to' object inside migrate_qmp() so and move the calls to migrate_get_socket_address() inside migrate_qmp. Also, replace connect_uri with args->connect_uri everywhere. Patch 3-6: --------- Add channels argument to allow both migration QAPI arguments independently into migrate_qmp and migrate_qmp_fail. migrate_qmp requires the port value to be changed from 0 to port value coming from migrate_get_socket_address. Add migrate_set_ports to address this change of port value. Patch 7-8: --------- Add 2 negative tests to validate mutually exhaustive behaviour of migration QAPIs. Add a positive multifd_tcp_plain qtest with only channels as the initial entry point for migration QAPIs. v6->v7 Changelog: ---------------- 1. Rebased the series withthe latest master 2. Added "tests/qtest/migration" prefix in all patches. v5->v6 Changelog: ---------------- 1. Pass args->connect_channels variable instead of NULL while calling migrate_qmp for .../multifd/channels/plain/none test. Passing NULL beats the whole purpose of the test. v4->v5 Changelog: ---------------- 1. Remove redundant imports from migration-test.c after moving helper functions to migration-helpers.c 2. call migrate_get_socket_address(to) and internally let qdict_get() call “socket-address” parameter to make more sense to the reader. 3. qdict needs to be freed, other small fixups. v3->v4 Changelog: ---------------- 1. introduced migrate_get_connect_uri and migrate_get_connect_qdict to both used migrate_get_socket_address to get dest uri in socket- address, and then use SokcketAddress_to_qdict to convert it into qdict. 2. Misc code changes. v2->v3 Changelog: ----------------- 1. 'channels' introduction is not required now for migrate_qmp_incoming 2. Refactor the code into 7 different patches 3. 'channels' introduction is not required now for migrate_qmp_incoming 4. Remove custom function for converting string to MigrationChannelList 5. move calls for migrate_get_socket_address inside migrate_qmp so that migrate_set_ports can replace the QAPI's port with correct value.
