2017-07-14scripts/coccinelle/memory-region-init-ram.cocci: New scriptPeter Maydell1-0/+38
Add a coccinelle script that can be used to automatically convert manual sequences of memory_region_init_ram_nomigrate() vmstate_register_ram{,_global}() to use the new memory_region_init_ram() Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Message-id: 1499438577-7674-7-git-send-email-peter.maydell@linaro.org
2017-07-12qobject: Update coccinelle script to catch Q{INC, DEC}REFEric Blake1-0/+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>
2017-06-20qapi: merge QInt and QFloat in QNumMarc-André Lureau1-2/+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.

2017-05-08qobject: Add helper macros for common scalar insertionsEric Blake1-0/+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.

2017-05-08coccinelle: Add script to remove useless QObject castsEric Blake1-0/+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.

2016-08-08error: Strip trailing '\n' from error string arguments (again)Markus Armbruster1-0/+29
Commit 9af9e0f, 6daf194d, be62a2eb and 312fd5f got rid of a bunch, but they keep coming back. checkpatch.pl tries to flag them since commit 5d596c2, but it's not very good at it. Offenders tracked down with Coccinelle script scripts/coccinelle/err-bad-newline.cocci, an updated version of the script from commit 312fd5f.

2016-06-20coccinelle: Remove unnecessary variables for function return valueEduardo Habkost1-0/+19
Use Coccinelle script to replace 'ret = E; return ret' with 'return E'. The script will do the substitution only when the function return type and variable type are the same. Manual fixups: * audio/audio.c: coding style of "read (...)" and "write (...)" * block/qcow2-cluster.c: wrap line to make it shorter * block/qcow2-refcount.c: change indentation of wrapped line * target-tricore/op_helper.c: fix coding style of "remainder|quotient" * target-mips/dsp_helper.c: reverted changes because I don't want to argue about checkpatch.pl * ui/qemu-pixman.c: fix line indentation * block/rbd.c: restore blank line between declarations and statements Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Message-Id: <1465855078-19435-4-git-send-email-ehabkost@redhat.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> [Unused Coccinelle rule name dropped along with a redundant comment; whitespace touched up in block/qcow2-cluster.c; stale commit message paragraph deleted] Signed-off-by: Markus Armbruster <armbru@redhat.com>
