[Qemu-devel] [PATCH v6 00/12] post-introspection cleanups, subset B

[Eric Blake]

Pending prerequisite: Markus' qapi-next branch (which has my
subset A patches):
git://repo.or.cz/qemu/armbru.git qapi-next
http://thread.gmane.org/gmane.comp.emulators.qemu/365827/focus=366351

Also available as a tag at this location:
git fetch git://repo.or.cz/qemu/ericb.git qapi-cleanupv6b

and I plan to eventually forcefully update my branch with the rest
of the v5 series, at:
http://repo.or.cz/qemu/ericb.git/shortlog/refs/heads/qapi

v6 notes: This is patches 11-16 of my v5 series; it has grown a bit
with splitting some patches and adding some others.  I suspect that
12/12 on this series will be discarded, but am including it because
it was split from v5 content.

Not much review comments other than on the original 11/46, but there
is enough churn due to rebasing that it's now easier to review this
version than plowing through v5.

Subset C (and more?) will come later.

001/12:[down] 'qapi: Use predicate callback to determine visit filtering'
002/12:[0043] [FC] 'qapi: Don't use info as witness of implicit object type'
003/12:[down] 'qapi: Lazy creation of array types'
004/12:[down] 'qapi: Create simple union type member earlier'
005/12:[0028] [FC] 'qapi: Track location that created an implicit type'
006/12:[0051] [FC] 'qapi: Track owner of each object member'
007/12:[0031] [FC] 'qapi: Detect collisions in C member names'
008/12:[0035] [FC] 'qapi: Defer duplicate member checks to schema check()'
009/12:[down] 'qapi: Defer duplicate enum value checks to schema check()'
010/12:[down] 'qapi: Correct error for union branch 'kind' clash'
011/12:[0002] [FC] 'qapi: Detect base class loops'
012/12:[down] 'RFC: qapi: Hide _info member'

In v5:
https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg05410.html
I _did_ rearrange patches to try and group related features:

1-2: Groundwork cleanups
3-5: Add more test cases
6-16: Front-end cleanups
17-18: Introspection output cleanups
19-20: 'alternate' type cleanups
21-29: qapi visitor cleanups
30-45: qapi-ify netdev_add
46: add qapi shorthand for flat unions

Lots of fixes based on additional testing, and rebased to
track other changes that happened in the meantime.  The series
is huge; I can split off smaller portions as requested.

In v4:
https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg02580.html
add some more clean up patches
rebase to Markus' recent work
pull in part of Zoltán's work to make netdev_add a flat union,
further enhancing it to be introspectible

I might be able to rearrange some of these patches, or separate
it into smaller independent series, if requested; but I'm
posting now to get review started.

In v3:
https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg02059.html
redo cleanup of dealloc of partial struct
add patches to make all visit_type_*() avoid leaks on failure
add patches to allow boxed command arguments and events

In v2:
https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg00900.html
rebase to Markus' v3 series
rework how comments are emitted for fields inherited from base
additional patches added for deleting colliding 'void *data'
documentation updates to match code changes

v1 was here:
https://lists.gnu.org/archive/html/qemu-devel/2015-07/msg05266.html
https://lists.gnu.org/archive/html/qemu-devel/2015-07/msg05325.html
