[Qemu-devel] [PATCH 0/4] Guarantee valid JSON in QMP, even for nonfinite numbers

[Eric Blake <eblake@redhat.com>]

Flesh out an idea that came up during my JSON visitor series.
Semantic errors are nicer than lexical errors.  While we generally
consider any non-finite number a bug in our code (that is, we
don't plan to expose them over QMP), at least we can guarantee
that even with a bug in our code we are still giving the user
valid JSON, similar to how we convert non-UTF-8 byte sequences
to use the replacement character for valid UTF-8 output.

I hit a couple of checkpatch false negatives in while writing this
series; one was easy to fix, but the other stumped me.  It doesn't
help that checkpatch tweaks also trigger checkpatch warnings...

Eric Blake (4):
  qobject: Correct JSON lexer grammar comments
  checkpatch: There is no qemu_strtod()
  qobject: Parse non-finite numbers, as an extension
  qobject: Output valid JSON for non-finite numbers
