With the previous commit, we have two different locations for detecting member name clashes - one at parse time, and another at QAPISchema*.check() time. Consolidate some of the checks into a single place, which is also in line with our TODO to eventually move all of the parse time semantic checking into the newer schema code. The check_member_clash() function is no longer needed. The wording of several error messages has changed, but in many cases feels like an improvement rather than a regression. The recent change (commit 7b2a5c2) to avoid an assertion failure when a flat union branch name collides with its discriminator name is also handled nicely by this code; but there is more work needed before we can detect all collisions in the generated enum associated with simple union branch names. No change to generated code. Signed-off-by: Eric Blake <eblake@redhat.com> --- v11 (no v10): no change v9: simplify on top of earlier check() improvements v8: decide whether to inline members based on union vs. alternate, not on flat vs. simple, and fix logic to avoid breaking union-clash-data in the process; add comments; assumes pull-qapi-2015-10-12 will go in without modifying commit ids v7: comment improvements, retitle subject v6: rebase to earlier testsuite improvements, fold in cleanup of flat-union-clash-type --- scripts/qapi.py | 34 +-------------------------- tests/qapi-schema/alternate-clash.err | 2 +- tests/qapi-schema/flat-union-clash-member.err | 2 +- tests/qapi-schema/struct-base-clash-deep.err | 2 +- tests/qapi-schema/struct-base-clash.err | 2 +- 5 files changed, 5 insertions(+), 37 deletions(-)
