[Qemu-devel] [PATCH v10 07/30] qapi: Simplify error cleanup in test-qmp-* |
Date: |
Thu, 5 Nov 2015 23:35:31 -0700 |
By moving err into data, we can let test teardown take care
of cleaning up any collected error; it also gives us fewer
lines of code between repeated tests where init runs teardown
on our behalf.
Rather than duplicate code between .c files, I added a new
test-qmp-common.h. I debated about putting
error_free_or_abort() in error.h, but it seems like something
that is only useful for tests.

v10: split in two pieces
v9: move earlier in series (was 14/17), reword commit message
v8: no change
v7: pick up whitespace changes dropped from earlier commit
v6: new patch
