2020-09-03qapi: enable use of g_autoptr with QAPI typesDaniel P. Berrangé
Currently QAPI generates a type and function for free'ing it: typedef struct QCryptoBlockCreateOptions QCryptoBlockCreateOptions; void qapi_free_QCryptoBlockCreateOptions(QCryptoBlockCreateOptions *obj); This is used in the traditional manner: QCryptoBlockCreateOptions *opts = NULL; opts = g_new0(QCryptoBlockCreateOptions, 1); ....do stuff with opts... qapi_free_QCryptoBlockCreateOptions(opts); Since bumping the min glib to 2.48, QEMU has incrementally adopted the use of g_auto/g_autoptr. This allows the compiler to run a function to free a variable when it goes out of scope, the benefit being the compiler can guarantee it is freed in all possible code ptahs. This benefit is applicable to QAPI types too, and given the seriously long method names for some qapi_free_XXXX() functions, is much less typing. This change thus makes the code generator emit: G_DEFINE_AUTOPTR_CLEANUP_FUNC(QCryptoBlockCreateOptions, qapi_free_QCryptoBlockCreateOptions) The above code example now becomes g_autoptr(QCryptoBlockCreateOptions) opts = NULL; opts = g_new0(QCryptoBlockCreateOptions, 1); ....do stuff with opts... Note, if the local pointer needs to live beyond the scope holding the variable, then g_steal_pointer can be used. This is useful to return the pointer to the caller in the success codepath, while letting it be freed in all error codepaths. return g_steal_pointer(&opts); The crypto/block.h header needs updating to avoid symbol clash now that the g_autoptr support is a standard QAPI feature.

2020-08-21libqemuutil, qapi, trace: convert to mesonPaolo Bonzini
This shows how to do some "computations" in meson.build using its array and dictionary data structures, and also a basic usage of the sourceset module for conditional compilation. Notice the new "if have_system" part of util/meson.build, which fixes a bug in the old build system was buggy: util/dbus.c was built even for non-softmmu builds, but the dependency on -lgio was lost when the linking was done through libqemuutil.a. Because all of its users required gio otherwise, the bug was hidden. Meson instead propagates libqemuutil's dependencies down to its users, and shows the problem.

2020-08-21meson: rename included C source files to .c.incPaolo Bonzini
With Makefiles that have automatically generated dependencies, you generated includes are set as dependencies of the Makefile, so that they are built before everything else and they are available when first building the .c files. Alternatively you can use a fine-grained dependency, e.g. target/arm/translate.o: target/arm/decode-neon-shared.inc.c With Meson you have only one choice and it is a third option, namely "build at the beginning of the corresponding target"; the way you express it is to list the includes in the sources of that target. The problem is that Meson decides if something is a source vs. a generated include by looking at the extension: '.c', '.cc', '.m', '.C' are sources, while everything else is considered an include---including '.inc.c'. Use '.c.inc' to avoid this, as it is consistent with our other convention of using '.rst.inc' for included reStructuredText files. The editorconfig file is adjusted.

2020-08-21trace: switch position of headers to what Meson requiresPaolo Bonzini
Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.

2020-08-21oss-fuzz/build: remove LIB_FUZZING_ENGINEPaolo Bonzini
Meson build scripts will only include qemu-fuzz-TARGET rules if configured with --enable-fuzzing, and that takes care of adding -fsanitize=fuzzer. Therefore we can just specify the configure option and stop modifying the CFLAGS and CONFIG_FUZZ options in the "make" invocation. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2020-07-30tracetool: carefully define SDT_USE_VARIADICStefan Hajnoczi
The dtrace backend defines SDT_USE_VARIADIC as a workaround for a conflict with a LTTng UST header file, which requires SDT_USE_VARIADIC to be defined. LTTng UST <lttng/tracepoint.h> breaks if included after generated dtrace headers because SDT_USE_VARIADIC will already be defined: #ifdef LTTNG_UST_HAVE_SDT_INTEGRATION #define SDT_USE_VARIADIC <-- error, it's already defined #include <sys/sdt.h> Be more careful when defining SDT_USE_VARIADIC.

2020-07-07tracetool: work around ust <sys/sdt.h> include conflictStefan Hajnoczi
Both the dtrace and ust backends may include <sys/sdt.h> but LTTng Userspace Tracer 2.11 and later requires SDT_USE_VARIADIC to be defined before including the header file. This is a classic problem with C header files included from different parts of a program. If the same header is included twice within the same compilation unit then the first inclusion determines the macro environment. Work around this by defining SDT_USE_VARIADIC in the dtrace backend too. It doesn't hurt and fixes a missing STAP_PROBEV() compiler error when the ust backend is enabled together with the dtrace backend.

2020-06-24scripts/tracetool: Update maintainer email addressPhilippe Mathieu-Daudé
There is an effort in progress to generate a QEMU Python package. As I'm not sure this old email is still valid, update it to not produce package with broken maintainer email. Patch created mechanically by running: $ sed -i 's,\(__email__ *= "\)stefanha@linux.vnet.ibm.com",\1stefanha@redhat.com",' \ $(git grep -l 'email.*stefanha@linux.vnet.ibm.com') Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Reviewed-by: John Snow <jsnow@redhat.com> Message-id: 20200511082816.696-1-philmd@redhat.com Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2020-06-23minikconf: explicitly set encoding to UTF-8Stefan Hajnoczi
QEMU currently only has ASCII Kconfig files but Linux actually uses UTF-8. Explicitly specify the encoding and that we're doing text file I/O. It's unclear whether or not QEMU will ever need Unicode in its Kconfig files. If we start using the help text then it will become an issue sooner or later. Make this change now for consistency with Linux Kconfig.

It is neater to keep this in the QEMU repo, since any change that requires an update to the oss-fuzz build configuration, can make the necessary changes in the same series.
