[Qemu-devel] [PATCH v4 0/2] Fixes/tests for hmp_object_del()

[Michael Roth <mdroth@linux.vnet.ibm.com>]

hmp_object_del() followed by a subsequent hmp_object_add() can trigger a
duplicate ID error if the previous object shared the same ID and was added
via the command-line. Please see patch 2/2 for more details.

This patchset fixes the issue in question and adds some general unit tests
for object created via -object, which we later extend to verify the fix in
question.

Changes since v3:

  - Fixed up comment formating (Markus)
  - Instead of segfaulting, use &error_abort if assumptions about
    'object' property group existence change (Markus)
  - Use g_assert_null in place of g_assert(... == NULL) (Markus)

Changes since v2:

  - Moved the generic unit tests ahead of the fix patch, with a FIXME
    in place of the actual check for the failure addressed in patch
    2/2 (Daniel/Markus)
  - Dropped check for existence of objects' QemuOptsList (Markus)
  - Dropped unintended whitespace removal in PATCH 1/2
  - Slight rewording of commit messages to reflect the changes and fix
    minor grammar errors.

Changes since v1:

  - Moved QemuOpt cleanup out of {qmp,hmp}_object_del() and into common
    user_creatable_del() path (Daniel, David)
  - Added corresponding test case in check-qom-proplist
