Alexander Bulekov 211635b3a2 fuzz: add oss-fuzz build-script
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.

Paolo Bonzini fbb84f0741 run-coverity-scan: support --update-tools-only --docker
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.

Paolo Bonzini 7265905940 run-coverity-scan: use docker.py
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.

Richard Henderson fe079aa13d decodetree: Drop check for less than 2 patterns in a group
While it makes little sense for the end product to have a group
containing only a single pattern, avoiding this case within an
incremental patch set is troublesome.

Because this is expected to be a transient condition, do not
bother "optimizing" this case, e.g. by folding away the group.

Richard Henderson 08561fc128 decodetree: Move semantic propagation into classes
Create ExcMultiPattern to hold an set of non-overlapping patterns.
The body of build_tree, prop_format become member functions on this
class.  Add minimal member functions to Pattern and MultiPattern
to allow recusion through the tree.

Move the bulk of build_incmulti_pattern to prop_masks and prop_width
in MultiPattern, since we will need this for both kinds of containers.
Only perform prop_width for variablewidth.

Remove global patterns variable, and pass down container object into
parse_file from main.

No functional change in all of this.

An alternate type's visit_type_FOO() fails when it runs into an
invalid ->type.

This is appropriate with an input visitor: visit_start_alternate()
sets ->type according to the input, and bad input can lead to bad
->type.

It should never happen with an output, clone or dealloc visitor: if it
did, the alternate being output, cloned or deallocated would be messed
up beyond repair.  Assert that.

Markus Armbruster c978bd5226 qapi: Clean up visitor's recovery from input with invalid type
An alternate type's visit_type_FOO() fails when it runs into an
invalid ->type.  If it's an input visit, we then need to free the the
object we got from visit_start_alternate().  We do that with
qapi_free_FOO(), which uses the dealloc visitor.

Trouble is that object is in a bad state: its ->type is invalid.  So
the dealloc visitor will run into the same error again, and the error
recovery skips deallocating the alternate's (invalid) alternative.
Works, because qapi_free_FOO() ignores the error.

Avoid it instead: free the messed up object with by g_free().

  If typedef-like declaration:

    Invalid C declaration: Expected identifier in nested name. [error at 21]

because it wants us to use the new-in-3.0 'c:struct' instead.

Plumb the Sphinx version through to the kernel-doc script

Peter Maydell a62d563796 scripts/kernel-doc: Add missing close-paren in c:function directives
When kernel-doc generates a 'c:function' directive for a function
one of whose arguments is a function pointer, it fails to print
the close-paren after the argument list of the function pointer
argument, for instance in the memory API documentation:
  .. c:function:: void memory_region_init_resizeable_ram (MemoryRegion * mr, struct Object * owner, const char * name, uint64_t size, uint64_t max_size, void (*resized) (const char*, uint64_t length, void *host, Error ** errp)

which should have a ')' after the 'void *host' which is the
last argument to 'resized'.

Older versions of Sphinx don't try to parse the argumnet
to c:function, but Sphinx 3.0 does do this and will complain:

  /home/petmay01/linaro/qemu-from-laptop/qemu/docs/../include/exec/memory.h:834: WARNING: Error in declarator or parameters
  Invalid C declaration: Expecting "," or ")" in parameters, got "EOF". [error at 208]
    void memory_region_init_resizeable_ram (MemoryRegion * mr, struct Object * owner, const char * name, uint64_t size, uint64_t max_size, void (*resized) (const char*, uint64_t length, void *host, Error ** errp)
    ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------^

Add the missing close-paren.

Peter Maydell 9c263d07fd scripts/run-coverity-scan: Script to run Coverity Scan build
Add a new script to automate the process of running the Coverity
Scan build tools and uploading the resulting tarball to the
website.

This is intended eventually to be driven from Travis,
but it can be run locally, if you are a maintainer of the
QEMU project on the Coverity Scan website and have the secret
upload token.

The script must be run on a Fedora 30 system.  Support for using a
Docker container is added in a following commit.

Philippe Mathieu-Daudé b412378785 decodetree: Use Python3 floor division operator
This script started using Python2, where the 'classic' division
operator returns the floor result. In commit 3d004a371 we started
to use Python3, where the division operator returns the float
result ('true division').
To keep the same behavior, use the 'floor division' operator "//"
which returns the floor result.
