The qapi builtin type 'int' is basically shorthand for the type
'int64'. In fact, since no visitor was providing the optional
type_int64() callback, visit_type_int64() was just always falling
back to type_int(), cementing the equivalence between the types.
However, some visitors are providing a type_uint64() callback.
For purposes of code consistency, it is nicer if all visitors
use the paired type_int64/type_uint64 names rather than the
mismatched type_int/type_uint64. So this patch just renames
the signed int callbacks in place, dropping the type_int()
callback as redundant, and a later patch will focus on the
unsigned int callbacks.
Add some FIXMEs to questionable reuse of errp in code touched
by the rename, while at it (the reuse works as long as the
callbacks don't modify value when setting an error, but it's not
a good example to set) - a later patch will then fix those.
No change in functionality here, although further cleanups are
in the pipeline.
Backports commit 4c40314a35816de635e7170eaacdc0c35be83a8a from qemu
The macro DO_UPCAST() is incorrectly named: it converts from a
parent class to a derived class (which is a downcast). Better,
and more consistent with some of the other qapi visitors, is
to use the container_of() macro through a to_FOO() helper. Names
like 'to_ov()' may be a bit short, but for a static helper it
doesn't hurt too much, and matches existing practice in files
like qmp-input-visitor.c.
Our current definition of container_of() is weaker than
DO_UPCAST(), in that it does not require the derived class to
have Visitor as its first member, but this does not hurt our
usage patterns in qapi visitors.
Backports commit d7bea75d35a44023efc9d481d3a1a2600677b2ef from qemu
Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.
This commit was created with scripts/clean-includes.
Backports commit cbf21151906c935d4276268b59429c58546462ae from qemu
qobject_to_qstring() crashes on null, which is a trap for the unwary.
Return null instead, and simplify a few callers.
Backports commit 7f0278435df1fa845b3bd9556942f89296d4246b from qemu
qobject_to_qfloat() and qobject_to_qint() crash on null, which is a
trap for the unwary. Return null instead, and simplify a few callers.
Backports commit fcf73f66a67f5e58c18216f8c8651e38cf4d90af from qemu
qobject_to_qbool() crashes on null, which is a trap for the unwary.
Return null instead, and simplify a few callers.
Backports commit 14b6160099f0caf5dc9d62e637b007bc5d719a96 from qemu
These macros expand into error class enumeration constant, comma,
string. Unclean. Has been that way since commit 13f59ae.
The error class is always ERROR_CLASS_GENERIC_ERROR since the previous
commit.
* Prepend every use of a QERR_ macro by ERROR_CLASS_GENERIC_ERROR, and
delete it from the QERR_ macro. No change after preprocessing.
* Rewrite error_set(ERROR_CLASS_GENERIC_ERROR, ...) into
error_setg(...). Again, no change after preprocessing.
Backports commit c6bd8c706a799eb0fece99f468aaa22b818036f3 from qemu
We require a C99 compiler, so let's use 'bool' instead of 'int'
when dealing with boolean values. There are few enough clients
to fix them all in one pass.
