I really wish we could teach CodeQL that for some functions that have a MonoError *
argument, that if is_ok (error)
then the return value is non-null. Otherwise these kinds of assertions are pretty lame.

Looks ok, but I wish we could systematically fix these code patterns:
SomeResult *result = callee(arg1, arg, error);
mono_error_assert_ok (error); // we should get to know that result != NULL here
by adding some kind of annotation to callee
.
Yeah, I'm not sure whether there is no relevant annotation or if the annotations just aren't documented. |
CodeQL flagged various places where we're dereferencing pointers that could be NULL, this PR systematically cleans some of them up via g_assert. (Note that CodeQL doesn't currently recognize g_assert as an assertion... working on that)
