* libqemuutil, qapi, trace: convert to mesonPaolo Bonzini2020-08-214-6/+2Star
| | | | | | | | | | | | | | | 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.

* meson: add testsuite Makefile generatorPaolo Bonzini2020-08-211-0/+102
| | | | | | | | | | | | Rules to execute tests are generated by a simple Python program that integrates into the existing "make check" mechanism. This provides familiarity for developers, and also allows piecewise conversion of the testsuite Makefiles to meson. The generated rules are based on QEMU's existing test harness Makefile and TAP parser. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* configure: integrate Meson in the build systemPaolo Bonzini2020-08-211-0/+1002
| | | | | | | | | | The Meson build system is integrated in the existing configure/make steps by invoking Meson from the configure script and converting Meson's build.ninja rules to an included Makefile. build.ninja already provides tags/ctags/cscope rules, so they are removed. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* meson: rename included C source files to .c.incPaolo Bonzini2020-08-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* trace: switch position of headers to what Meson requiresPaolo Bonzini2020-08-213-6/+3Star
| | | | | | | | | | | | | | | | | 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.

* oss-fuzz/build: remove LIB_FUZZING_ENGINEPaolo Bonzini2020-08-211-11/+5Star
| | | | | | | | | 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>

* tracetool: carefully define SDT_USE_VARIADICStefan Hajnoczi2020-07-301-0/+4
| | | | | | | | | | | | | | | | | | | | | 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. This fixes the build when both the dtrace and ust tracers are enabled at the same time.

| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just build the container when run-coverity-scan is invoked with --update-tools-only --docker. This requires moving the "docker build" logic into the update_coverity_tools function. The only snag is that --update-tools-only --docker requires access to the dockerfile. For now just report an error for --src-tarball, and "docker build" will fail if not in a source tree. Another possibility could be to host our container images on a public registry, and use "FROM qemu:fedora" to make the Dockerfile small enough that it can be included directly in the run-coverity-scan script.

| | | | | | | | | | | | | | | | | | | | | | | | | | Our trusted docker wrapper allows run-coverity-scan to run with both docker and podman. For the "run" phase this is transparent; for the "build" phase however scripts are replaced with a bind mount (-v). This is not an issue because the secret option is meant for secrets stored globally in the system and bind mounts are a valid substitute for secrets that are known to whoever builds the container.
