2020-12-19qapi: Use QAPI_LIST_PREPEND() where possibleEric Blake1-8/+4
Anywhere we create a list of just one item or by prepending items (typically because order doesn't matter), we can use QAPI_LIST_PREPEND(). But places where we must keep the list in order by appending remain open-coded until later patches. Note that as a side effect, this also performs a cleanup of two minor issues in qga/commands-posix.c: the old code was performing new = g_malloc0(sizeof(*ret)); which 1) is confusing because you have to verify whether 'new' and 'ret' are variables with the same type, and 2) would conflict with C++ compilation (not an actual problem for this file, but makes copy-and-paste harder).

2020-10-17build: replace ninjatool with ninjaPaolo Bonzini1-4/+2
Now that the build is done entirely by Meson, there is no need to keep the Makefile conversion. Instead, we can ask Ninja about the targets it exposes and forward them. The main advantages are, from smallest to largest: - reducing the possible namespace pollution within the Makefile - removal of a relatively large Python program - faster build because parsing Makefile.ninja is slower than parsing build.ninja; and faster build after Meson runs because we do not have to generate Makefile.ninja. - tracking of command lines, which provides more accurate rebuilds In addition the change removes the requirement for GNU make 3.82, which was annoying on Mac, and avoids bugs on Windows due to ninjatool not knowing how to convert Windows escapes to POSIX escapes.

2020-10-09hmp: Add support for coroutine command handlersKevin Wolf1-2/+2
Often, QMP command handlers are not only called to handle QMP commands, but also from a corresponding HMP command handler. In order to give them a consistent environment, optionally run HMP command handlers in a coroutine, too. The implementation is a lot simpler than in QMP because for HMP, we still block the VM while the coroutine is running.

2020-10-05scripts: add block-coroutine-wrapper.pyVladimir Sementsov-Ogievskiy2-0/+55
We have a very frequent pattern of creating a coroutine from a function with several arguments: - create a structure to pack parameters - create _entry function to call original function taking parameters from struct - do different magic to handle completion: set ret to NOT_DONE or EINPROGRESS or use separate bool field - fill the struct and create coroutine from _entry function with this struct as a parameter - do coroutine enter and BDRV_POLL_WHILE loop Let's reduce code duplication by generating coroutine wrappers. This patch adds scripts/block-coroutine-wrapper.py together with some friends, which will generate functions with declared prototypes marked by the 'generated_co_wrapper' specifier. The usage of new code generation is as follows: 1. define the coroutine function somewhere int coroutine_fn bdrv_co_NAME(...) {...} 2. declare in some header file int generated_co_wrapper bdrv_NAME(...); with same list of parameters (generated_co_wrapper is defined in "include/block/block.h"). 3. Make sure the block_gen_c declaration in block/meson.build mentions the file with your marker function. Still, no function is now marked, this work is for the following commit.

Update the documentation of QAPI document comment syntax to match the new rST backend requirements. The principal changes are: * whitespace is now significant, and multiline definitions must have their second and subsequent lines indented to match the first line * general rST format markup is permitted, not just the small set of markup the old texinfo generator handled. For most things (notably bulleted and itemized lists) the old format was the same as rST is. * Specific things that might trip people up: - instead of *bold* and _italic_ rST has **bold** and *italic* - lists need a preceding and following blank line - a lone literal '*' will need to be backslash-escaped to avoid a rST syntax error * the old leading '|' for example (literal text) blocks is replaced by the standard rST '::' literal block. * we support arbitrary levels of sub- and sub-sub-heading, not just a main and sub-heading like the old texinfo generator * lists can now be nested Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-Id: <20200925162316.21205-18-peter.maydell@linaro.org> Reviewed-by: Markus Armbruster <armbru@redhat.com> [Commit message improved slightly] Signed-off-by: Markus Armbruster <armbru@redhat.com>
2020-09-29scripts/qapi/parser.py: improve doc comment indent handlingPeter Maydell1-0/+23
Make the handling of indentation in doc comments more sophisticated, so that when we see a section like: Notes: some text some more text indented line 3 we save it for the doc-comment processing code as: some text some more text indented line 3 and when we see a section with the heading on its own line: Notes: some text some more text indented text we also accept that and save it in the same form. If we detect that the comment document text is not indented as much as we expect it to be, we throw a parse error. (We don't complain about over-indented sections, because for rST this can be legitimate markup.) The golden reference for the doc comment text is updated to remove the two 'wrong' indents; these now form a test case that we correctly stripped leading whitespace from an indented multi-line argument definition. We update the documentation in docs/devel/qapi-code-gen.txt to describe the new indentation rules.

2020-09-23qemu/atomic.h: rename atomic_ to qatomic_Stefan Hajnoczi3-89/+89
clang's C11 atomic_fetch_*() functions only take a C11 atomic type pointer argument. QEMU uses direct types (int, etc) and this causes a compiler error when a QEMU code calls these functions in a source file that also included <stdatomic.h> via a system header file: $ CC=clang CXX=clang++ ./configure ... && make ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid) Avoid using atomic_*() names in QEMU's atomic.h since that namespace is used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h and <stdatomic.h> can co-exist. I checked /usr/include on my machine and searched GitHub for existing "qatomic_" users but there seem to be none. This patch was generated using: $ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \ sort -u >/tmp/changed_identifiers $ for identifier in $(</tmp/changed_identifiers); do sed -i "s%\<$identifier\>%q$identifier%g" \ $(git grep -I -l "\<$identifier\>") done I manually fixed line-wrap issues and misaligned rST tables.

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.

2020-09-01meson: use pkg-config method to find dependenciesPaolo Bonzini1-13/+14
We do not need to ask cmake for the dependencies, so just use the pkg-config mechanism. Keep "auto" for SDL so that it tries using sdl-config too. The documentation is adjusted to use SDL2_image as the example, rather than SDL which does not use the "pkg-config" method. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2020-08-21libqemuutil, qapi, trace: convert to mesonPaolo Bonzini1-1/+1
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.
