2021-05-12coverity-scan: list components, move model to scripts/coverity-scanPaolo Bonzini2-0/+154
Place all files that can be useful to rebuild the Coverity configuration in scripts/coverity-scan: the existing model file, and the components setup. The Markdown syntax was tested with Pandoc (but in any case is meant more as a human-readable reference than as a part of documentation).

2021-04-30qapi/error.py: move QAPIParseError to parser.pyJohn Snow2-15/+21
Keeping it in error.py will create some cyclic import problems when we add types to the QAPISchemaParser. Callers don't need to know the details of QAPIParseError unless they are parsing or dealing directly with the parser, so this won't create any harsh new requirements for callers in the general case. Update error.py with a little docstring that gives a nod to where the error may now be found.

2021-04-30qapi/error: assert QAPISourceInfo is not NoneJohn Snow1-0/+1
Built-in stuff is not parsed from a source file, and therefore have no QAPISourceInfo. If such None info was used for reporting an error, built-in stuff would be broken. Programming error. Instead of reporting a confusing error with bogus source location then, we better crash. We currently crash only if self.col was set. Assert that self.info is not None in order to crash reliably. We can not yet change the type of the initializer to prove this cannot happen at static analysis time before the remainder of the code is fully typed.

It's already treated as optional, with one direct caller and some subclass callers passing 'None'.

Rename QAPIError to QAPISourceError, and then create a new QAPIError class that serves as the basis for all of our other custom exceptions, without specifying any class properties. This leaves QAPIError as a package-wide error class that's suitable for any current or future errors.

Per list review: qapi-code-gen.txt reserves suffixes Kind and List only for type names, but the code rejects them for events and commands, too.

2021-04-30qapi/expr.py: Consolidate check_if_str calls in check_ifJohn Snow1-17/+16
This is a small rewrite to address some minor style nits. Don't compare against the empty list to check for the empty condition, and move the normalization forward to unify the check on the now-normalized structure. With the check unified, the local nested function isn't needed anymore and can be brought down into the normal flow of the function. With the nesting level changed, shuffle the error strings around a bit to get them to fit in 79 columns. Note: although ifcond is typed as Sequence[str] elsewhere, we *know* that the parser will produce real, bona-fide lists. It's okay to check isinstance(ifcond, list) here.

(Iterable would also have worked, but Iterable also includes things like generator expressions which are consumed upon iteration, which would require a rewrite to make sure that each input was only traversed once.

Casts are instructions to the type checker only, they aren't "safe" and should probably be avoided in general. In this case, when we perform type checking on a nested structure, the type of each field does not "stick". (See PEP 647 for an example of "type narrowing" that does "stick". It is available in Python 3.10, so we can't use it yet.) We don't need to assert that something is a str if we've already checked or asserted that it is -- use a cast instead for these cases.

Flat union branch names match the tag enum's member names. Omitted branches default to "no members for this tag value". Branch names starting with a digit get rejected like "'data' member '0' has an invalid name". However, omitting the branch works. This is because flat union tag values get checked twice: as enum member name, and as union branch name. The former accepts leading digits, the latter doesn't. Branches whose names start with a digit therefore cannot have members. Feels wrong. Get rid of the restriction by skipping the latter check. This can expose c_name() to input it can't handle: a name starting with a digit. Improve it to return a valid C identifier for any input.

2021-03-23qapi: Fix to reject optional members with reserved namesMarkus Armbruster1-5/+4
check_type() fails to reject optional members with reserved names, because it neglects to strip off the leading '*'. Fix that. The stripping in check_name_str() is now useless. Drop. Also drop the "no leading '*'" assertion, because valid_name.match() ensures it can't fail.

2021-03-19qapi: Implement deprecated-input=reject for QMP command argumentsMarkus Armbruster2-2/+4
This policy rejects deprecated input, and thus permits "testing the future". Implement it for QMP command arguments: reject commands with deprecated ones. Example: when QEMU is run with -compat deprecated-input=reject, then {"execute": "eject", "arguments": {"device": "cd"}} fails like this {"error": {"class": "GenericError", "desc": "Deprecated parameter 'device' disabled by policy"}} When the deprecated parameter is removed, the error will change to {"error": {"class": "GenericError", "desc": "Parameter 'device' is unexpected"}} Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-Id: <20210318155519.1224118-11-armbru@redhat.com>
