[PATCH 00/22] qapi: Remove simple unions from the schema language |
Date: |
Mon, 13 Sep 2021 14:39:10 +0200 |
Simple unions predate flat unions. Having both complicates the QAPI
schema language and the QAPI generator. We haven't been using simple
unions in new code for a long time, because they are less flexible and
somewhat awkward on the wire.
Get rid of them. We should've done this long ago.
This adds some boilerplate to the schema:
$ git-diff --shortstat master qapi
7 files changed, 461 insertions(+), 59 deletions(-)
Well worth the language simplification, in my opinion:
$ git-diff --stat master scripts/ docs/
docs/devel/qapi-code-gen.rst | 137
++++++++++---------------------------------
scripts/qapi/common.py | 19 ++----
scripts/qapi/expr.py | 48 +++++++--------
scripts/qapi/schema.py | 101 +++++++------------------------
4 files changed, 80 insertions(+), 225 deletions(-)
The complete diffstat looks even better, but is somewhat misleading,
because it's dominated by two tests rewritten in a much more compact
way.
This series is based on my "[PULL 0/5] QAPI patches patches for
2021-09-13".
