From fb0bc835e56b894cbc7236294921e5393c786ad8 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 26 Feb 2018 13:48:58 -0600 Subject: [PATCH] qapi-gen: New common driver for code and doc generators MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Whenever qapi-schema.json changes, we run six programs eleven times to update eleven files. Similar for qga/qapi-schema.json. This is silly. Replace the six programs by a single program that spits out all eleven files. The programs become modules in new Python package qapi, along with the helper library. This requires moving them to scripts/qapi/. While moving them, consistently drop executable mode bits.
