Paolo Bonzini	d1000ecae2	include: move hw/qdev-core.h to hw/core/, rename Call it hw/core/qdev.h to avoid the duplication in the name. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	8 months ago
Daniel P. Berrangé	407bc4bf90	qapi: Move include/qapi/qmp/ to include/qobject/ The general expectation is that header files should follow the same file/path naming scheme as the corresponding source file. There are various historical exceptions to this practice in QEMU, with one of the most notable being the include/qapi/qmp/ directory. Most of the headers there correspond to source files in qobject/. This patch corrects most of that inconsistency by creating include/qobject/ and moving the headers for qobject/ there. This also fixes MAINTAINERS for include/qapi/qmp/dispatch.h: scripts/get_maintainer.pl now reports "QAPI" instead of "No maintainers found". Signed-off-by: Daniel P.

Markus Armbruster	eab3a4678b	qobject: Change qobject_to_json()'s value to GString qobject_to_json() and qobject_to_json_pretty() build a GString, then covert it to QString. Just one of the callers actually needs a QString: qemu_rbd_parse_filename(). A few others need a string they can modify: qmp_send_response(), qga's send_response(), to_json_str(), and qmp_fd_vsend_fds(). The remainder just need a string. Change qobject_to_json() and qobject_to_json_pretty() to return the GString. qemu_rbd_parse_filename() now has to convert to QString. All others save a QString temporary. to_json_str() actually becomes a bit simpler, because GString provides more convenient modification functions.

Markus Armbruster	0dde9fd12f	qom: Make info qom-tree sort children more efficiently Commit `e8c9e65816` "qom: Make "info qom-tree" show children sorted" sorts children the simple, stupid, quadratic way. I thought the number of children would be small enough for this not to matter. I was wrong: there are outliers with several hundred children, e.g ARM machines nuri and smdkc210 each have a node with 513 children. While n^2 sorting isn't noticeable in normal, human usage even for n=513, it can be quite noticeable in certain automated tests. In particular, the sort made device-introspect-test even slower. Commit `3e7b80f84d` "tests: improve performance of device-introspect-test" just fixed that by cutting back its excessive use of "info qom-tree". Sorting more efficiently makes sense regardless, so do it.

Markus Armbruster	7a309cc95b	qom: Change object_get_canonical_path_component() not to malloc object_get_canonical_path_component() returns a malloced copy of a property name on success, null on failure. 19 of its 25 callers immediately free the returned copy. Change object_get_canonical_path_component() to return the property name directly. Since modifying the name would be wrong, adjust the return type to const char *. Drop the free from the 19 callers become simpler, add the g_strdup() to the other six.

Markus Armbruster	ab2d185d6b	qom: Plug memory leak in "info qom-tree" Commit `e8c9e65816` "qom: Make "info qom-tree" show children sorted" created a memory leak, because I didn't realize object_get_canonical_path_component()'s value needs to be freed. Reproducer: $ qemu-system-x86_64 -nodefaults -display none -S -monitor stdio QEMU 5.0.50 monitor - type 'help' for more information (qemu) info qom-tree This leaks some 4500 path components, 12-13 characters on average, i.e. roughly 100kBytes depending on the allocator. A couple of hundred "info qom-tree" here, a couple of hundred there, and soon enough we're talking about real memory. Plug the leak.

Markus Armbruster	5325cc34a2	qom: Put name parameter before value / visitor parameter The object_property_set_FOO() setters take property name and value in an unusual order: void object_property_set_FOO(Object obj, FOO_TYPE value, const char name, Error **errp) Having to pass value before name feels grating. Swap them. Same for object_property_set(), object_property_get(), and object_property_parse(). Convert callers with this Coccinelle script: @@ identifier fun = { object_property_get, object_property_parse, object_property_set_str, object_property_set_link, object_property_set_bool, object_property_set_int, object_property_set_uint, object_property_set, object_property_set_qobject }; expression obj, v, name, errp; @@ - fun(obj, v, name, errp) + fun(obj, name, v, errp) Chokes on hw/arm/musicpal.c's lcd_refresh() with the unhelpful error message "no position information". Convert that one manually. Fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Convert manually. Fails to convert hw/rx/rx-gdbsim.c, because Coccinelle gets confused by RXCPU being used both as typedef and function-like macro there. Convert manually. The other files using RXCPU that way don't need conversion.

David Hildenbrand	2d9e3dd9be	hmp: Make json format optional for qom-set Commit `7d2ef6dcc1` ("hmp: Simplify qom-set") switched to the json parser, making it possible to specify complex types. However, with this change it is no longer possible to specify proper sizes (e.g., 2G, 128M), turning the interface harder to use for properties that consume sizes. Let's switch back to the previous handling and allow to specify passing json via the "-j" parameter.
