2018-03-02qapi: Empty out qapi-schema.jsonMarkus Armbruster1-1/+2
The previous commit improved compile time by including less of the generated QAPI headers. This is impossible for stuff defined directly in qapi-schema.json, because that ends up in headers that that pull in everything. Move everything but include directives from qapi-schema.json to new sub-module qapi/misc.json, then include just the "misc" shard where possible. It's possible everywhere, except: * monitor.c needs qmp-command.h to get qmp_init_marshal() * monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need qapi-event.h to get enum QAPIEvent Perhaps we'll get rid of those some other day. Adding a type to qapi/migration.json now recompiles some 120 instead of 2300 out of 5100 objects.

2018-02-14qmp-test: Drop dependence on global_qtestEric Blake1-17/+18
As a general rule, we prefer avoiding implicit global state because it makes code harder to safely copy and paste without thinking about the global state. Although qmp-test does not maintain parallel qtest connections, it was the last test assigning to global_qtest. It's just as easy to be explicit about the state; once all tests have been cleaned up, a later patch can then get rid of global_qtest and a layer of wrappers in libqtest.

2018-02-09Include qapi/qmp/qdict.h exactly where neededMarkus Armbruster1-0/+1
This cleanup makes the number of objects depending on qapi/qmp/qdict.h drop from 4550 (out of 4743) to 368 in my "build everything" tree. For qapi/qmp/qobject.h, the number drops from 4552 to 390. While there, separate #include from file comment with a blank line.

2017-09-04qapi: Change data type of the FOO_lookup generated for enum FOOMarc-André Lureau1-1/+1
Currently, a FOO_lookup is an array of strings terminated by a NULL sentinel. A future patch will generate enums with "holes". NULL-termination will cease to work then. To prepare for that, store the length in the FOO_lookup by wrapping it in a struct and adding a member for the length. The sentinel will be dropped next.

2017-09-04tests/qmp-test: Add generic, basic test of query commandsMarkus Armbruster1-1/+181
A command is a query if it has no side effect and yields a result. Such commands are typically named query-FOO, but there are exceptions. The basic idea is to find candidates with query-qmp-schema, filter out the ones that aren't queries with an explicit blacklist, and test the remaining ones against a QEMU with no special arguments. The current blacklist is just add-fd. The test can't do queries with arguments, because it knows nothing about the arguments. No coverage for query-cpu-model-baseline, query-cpu-model-comparison, query-cpu-model-expansion, query-rocker, query-rocker-ports, query-rocker-of-dpa-flows, and query-rocker-of-dpa-groups. Most tested commands are expected to succeed. The test does not check the return value then. query-balloon and query-vm-generation-id are expected to fail because they need a virtio-balloon / vmgenid device to succeed, and this test is too dumb to set one up. Could be addressed later. query-acpi-ospm-status and query-hotpluggable-cpus are expected to fail because they require features provided only by special machine types, and this test is too dumb to set that up. Could also be addressed later. Several commands may either be functional or stubs that always fail, depending on build configuration. Ideally, the stubs shouldn't be in query-qmp-schema, but that requires QAPI schema compile-time configuration, which we don't have, yet. Until we do, we need to figure out whether a command is a stub. When we have a suitable CONFIG_FOO preprocessor symbol is available, use that. Else, simply blacklist the command for now. We get basic test coverage for the following commands, except as noted: qom-list-types query-acpi-ospm-status (expected to fail) query-balloon (expected to fail) query-block query-block-jobs query-blockstats query-chardev query-chardev-backends query-command-line-options query-commands query-cpu-definitions (blacklisted for now) query-cpus query-dump query-dump-guest-memory-capability query-events query-fdsets query-gic-capabilities (blacklisted for now) query-hotpluggable-cpus (expected to fail) query-iothreads query-kvm query-machines query-memdev query-memory-devices query-mice query-migrate query-migrate-cache-size query-migrate-capabilities query-migrate-parameters query-name query-named-block-nodes query-pci (blacklisted for now) query-qmp-schema query-rx-filter query-spice query-status query-target query-tpm query-tpm-models query-tpm-types query-uuid query-version query-vm-generation-id (expected to fail) query-vnc query-vnc-servers query-xen-replication-status Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <1502461148-10154-1-git-send-email-armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> [Typos in code under #ifndef and in the commit message fixed]
