| | | | | | | | | | | | | | | | | | Wildcard includes become hard to manage when refactoring and dealing with circular dependencies with strictly typed mypy. flake8 also flags each one as a warning, as it is not smart enough to know which names exist in the imported file.

* qapi: Prefer explicit relative importsJohn Snow2020-10-101-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All of the QAPI include statements are changed to be package-aware, as explicit relative imports. A quirk of Python packages is that the name of the package exists only *outside* of the package. This means that to a module inside of the qapi folder, there is inherently no such thing as the "qapi" package. The reason these imports work is because the "qapi" package exists in the context of the caller -- the execution shim, where sys.path includes a directory that has a 'qapi' folder in it. When we write "from qapi import sibling", we are NOT referencing the folder 'qapi', but rather "any package named qapi in sys.path". If you should so happen to have a 'qapi' package in your path, it will use *that* package. When we write "from .sibling import foo", we always reference explicitly our sibling module; guaranteeing consistency in *where* we are importing these modules from. This can be useful when working with virtual environments and packages in development mode. In development mode, a package is installed as a series of symlinks that forwards to your same source files. The problem arises because code quality checkers will follow "import qapi.x" to the "installed" version instead of the sibling file and -- even though they are the same file -- they have different module paths, and this causes cyclic import problems, false positive type mismatch errors, and more. It can also be useful when dealing with hierarchical packages, e.g. if we allow qemu.core.qmp, qemu.qapi.parser, etc. Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Cleber Rosa <crosa@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20201009161558.107041-6-jsnow@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>

* qapi: Move gen_enum(), gen_enum_lookup() back to qapi/types.pyMarkus Armbruster2019-10-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | The next commit will split up qapi/common.py. gen_enum() needs QAPISchemaEnumMember, and that's in the way. Move it to qapi/types.py along with its buddy gen_enum_lookup(). Permit me a short a digression on history: how did gen_enum() end up in qapi/common.py? Commit 21cd70dfc1 "qapi script: add event support" duplicated qapi-types.py's gen_enum() and gen_enum_lookup() in qapi-event.py. Simply importing them would have been cleaner, but wasn't possible as qapi-types.py was a program, not a module. Commit efd2eaa6c2 "qapi: De-duplicate enum code generation" de-duplicated by moving them to qapi.py, which was a module. Since then, program qapi-types.py has morphed into module types.py. It's where gen_enum() and gen_enum_lookup() started, and where they belong.

| | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 7bd263490590ee6fcf34ecb6203437e22f6e5a9c. The commit applied the events' conditions to the members of enum QAPIEvent. Awkward, because it renders QAPIEvent unusable in target-independent code as soon as we make an event target-dependent. Reverting this has the following effects: * ui/vnc.c can remain target independent. * monitor_qapi_event_conf[] doesn't have to muck around with #ifdef. * query-events again doesn't reflect conditionals. I'm going to deprecate it in favor of query-qmp-schema. Another option would be to split target-dependent parts off enum QAPIEvent into a target-dependent enum. Doesn't seem worthwhile right now.

* qapi: Clean up modular built-in code generation a bitMarkus Armbruster2019-02-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | We neglect to call .visit_module() for the special module we use for built-ins. Harmless, but clean it up anyway. The tests/qapi-schema/*.out now show the built-in module as 'module None'. Subclasses of QAPISchemaModularCVisitor need to ._add_module() this special module to enable code generation for built-ins. When this hasn't been done, QAPISchemaModularCVisitor.visit_module() does nothing for the special module. That looks like built-ins could accidentally be generated into the wrong module when a subclass neglects to call ._add_module(). Can't happen, because built-ins are all visited before any other module. But that's non-obvious. Switch off code generation explicitly. Rename QAPISchemaModularCVisitor._begin_module() to ._begin_user_module(). New QAPISchemaModularCVisitor._is_builtin_module(), for clarity.

* qapi: Eliminate indirection through qmp_event_get_func_emit()Markus Armbruster2019-01-241-10/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The qapi_event_send_FOO() functions emit events like this: QMPEventFuncEmit emit; emit = qmp_event_get_func_emit(); if (!emit) { return; } qmp = qmp_event_build_dict("FOO"); [put event arguments into @qmp...] emit(QAPI_EVENT_FOO, qmp); The value of qmp_event_get_func_emit() depends only on the program: * In qemu-system-FOO, it's always monitor_qapi_event_queue. * In tests/test-qmp-event, it's always event_test_emit. * In all other programs, it's always null. This is exactly the kind of dependence the linker is supposed to resolve; we don't actually need an indirection. Note that things would fall apart if we linked more than one QAPI schema into a single program: each set of qapi_event_send_FOO() uses its own event enumeration, yet they share a single emit function. Which takes the event enumeration as an argument. Which one if there's more than one? More seriously: how does this work even now? qemu-system-FOO wants QAPIEvent, and passes a function taking that to qmp_event_set_func_emit(). test-qmp-event wants test_QAPIEvent, and passes a function taking that to qmp_event_set_func_emit(). It works by type trickery, of course: typedef void (*QMPEventFuncEmit)(unsigned event, QDict *dict); void qmp_event_set_func_emit(QMPEventFuncEmit emit); QMPEventFuncEmit qmp_event_get_func_emit(void); We use unsigned instead of the enumeration type. Relies on both enumerations boiling down to unsigned, which happens to be true for the compilers we use. Clean this up as follows: * Generate qapi_event_send_FOO() that call PREFIX_qapi_event_emit() instead of the value of qmp_event_set_func_emit(). * Generate a prototype for PREFIX_qapi_event_emit() into qapi-events.h. * PREFIX_ is empty for qapi/qapi-schema.json, and test_ for tests/qapi-schema/qapi-schema-test.json. It's qga_ for qga/qapi-schema.json, and doc-good- for tests/qapi-schema/doc-good.json, but those don't define any events. * Rename monitor_qapi_event_queue() to qapi_event_emit() instead of passing it to qmp_event_set_func_emit(). This takes care of qemu-system-FOO. * Rename event_test_emit() to test_qapi_event_emit() instead of passing it to qmp_event_set_func_emit(). This takes care of tests/test-qmp-event. * Add a qapi_event_emit() that does nothing to stubs/monitor.c. This takes care of all other programs that link code emitting QMP events. * Drop qmp_event_set_func_emit(), qmp_event_get_func_emit().

* qapi: Generate separate .h, .c for each moduleMarkus Armbruster2018-03-021-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our qapi-schema.json is composed of modules connected by include directives, but the generated code is monolithic all the same: one qapi-types.h with all the types, one qapi-visit.h with all the visitors, and so forth. These monolithic headers get included all over the place. In my "build everything" tree, adding a QAPI type recompiles about 4800 out of 5100 objects. We wouldn't write such monolithic headers by hand. It stands to reason that we shouldn't generate them, either. Split up generated qapi-types.h to mirror the schema's modular structure: one header per module. Name the main module's header qapi-types.h, and sub-module D/B.json's header D/qapi-types-B.h. Mirror the schema's includes in the headers, so that qapi-types.h gets you everything exactly as before. If you need less, you can include one or more of the sub-module headers. To be exploited shortly. Split up qapi-types.c, qapi-visit.h, qapi-visit.c, qmp-commands.h, qmp-commands.c, qapi-event.h, qapi-event.c the same way. qmp-introspect.h, qmp-introspect.c and qapi.texi remain monolithic. The split of qmp-commands.c duplicates static helper function qmp_marshal_output_str() in qapi-commands-char.c and qapi-commands-misc.c. This happens when commands returning the same type occur in multiple modules. Not worth avoiding. Since I'm going to rename qapi-event.[ch] to qapi-events.[ch], and qmp-commands.[ch] to qapi-commands.[ch], name the shards that way already, to reduce churn. This requires temporary hacks in commands.py and events.py. Similarly, c_name() must temporarily be taught to munge '/' in common.py. They'll go away with the rename.

* qapi: Make code-generating visitors use QAPIGen moreMarkus Armbruster2018-03-021-34/+21Star
| | | | | | | | | | | | | | | The use of QAPIGen is rather shallow so far: most of the output accumulation is not converted. Take the next step: convert output accumulation in the code-generating visitor classes. Helper functions outside these classes are not converted.

* qapi-gen: New common driver for code and doc generatorsMarkus Armbruster2018-03-021-0/+204
Whenever qapi-schema.json changes, we run six programs eleven times to update eleven files. Similar for qga/qapi-schema.json. This is silly. Replace the six programs by a single program that spits out all eleven files. The programs become modules in new Python package qapi, along with the helper library. This requires moving them to scripts/qapi/. While moving them, consistently drop executable mode bits.
