* qobject: Replace qobject_incref/QINCREF qobject_decref/QDECREFMarc-André Lureau2018-05-041-4/+4
| | | | | | | | | | | | | | | | | | | | | Now that we can safely call QOBJECT() on QObject * as well as its subtypes, we can have macros qobject_ref() / qobject_unref() that work everywhere instead of having to use QINCREF() / QDECREF() for QObject and qobject_incref() / qobject_decref() for its subtypes. The replacement is mechanical, except I broke a long line, and added a cast in monitor_qmp_cleanup_req_queue_locked(). Unlike qobject_decref(), qobject_unref() doesn't accept void *. Note that the new macros evaluate their argument exactly once, thus no need to shout them.

* qobject: Update coccinelle script to catch Q{INC, DEC}REFEric Blake2017-07-121-0/+6
| | | | | | | | | | | | | | The recent commit b097efc0 used qobject_decref(QOBJECT(E)), even though we already have QDECREF(E) for that purpose. We can update our coccinelle script to catch any future relapses; with that in place, the rest of the patch is generated with: spatch --sp-file scripts/coccinelle/qobject.cocci \ --macro-file scripts/cocci-macro-file.h --dir . --in-place Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <20170624181008.25497-3-eblake@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>
* qapi: merge QInt and QFloat in QNumMarc-André Lureau2017-06-201-2/+2
| | | | | | | | | | | | | | | We would like to use a same QObject type to represent numbers, whether they are int, uint, or floats. Getters will allow some compatibility between the various types if the number fits other representations. Add a few more tests while at it.

* qobject: Add helper macros for common scalar insertionsEric Blake2017-05-081-0/+22
| | | | | | | | | | | | | | Rather than making lots of callers wrap a scalar in a QInt, QString, or QBool, provide helper macros that do the wrapping automatically. Update the Coccinelle script to make mass conversions easy, although the conversion itself will be done as a separate patches to ease review and backport efforts.

* coccinelle: Add script to remove useless QObject castsEric Blake2017-05-081-0/+13
We have macros in place to make it less verbose to add a subtype of QObject to both QDict and QList. While we have made cleanups like this in the past (see commit fcfcd8ffc, for example), having it be automated by Coccinelle makes it easier to maintain. The script is separate from the cleanups, for ease of review and backporting. A later patch will then add further possible cleanups.
