2016-01-18qom: Change object property iterator API contractDaniel P. Berrange1-4/+3
Currently the ObjectProperty iterator API works as follows: ObjectPropertyIterator *iter; iter = object_property_iter_init(obj); while ((prop = object_property_iter_next(iter))) { ... } object_property_iter_free(iter); This has the benefit that the ObjectPropertyIterator struct can be opaque, but has the downside that callers need to explicitly call a free function. It is also not in keeping with iterator style used elsewhere in QEMU/GLib2. This patch changes the API to use stack allocation instead: ObjectPropertyIterator iter; object_property_iter_init(&iter, obj); while ((prop = object_property_iter_next(&iter))) { ... } Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.

Now that we guarantee the user doesn't have any enum values beginning with a single underscore, we can use that for our own purposes. Renaming ENUM_MAX to ENUM__MAX makes it obvious that the sentinel is generated. This patch was mostly generated by applying a temporary patch: |diff --git a/scripts/qapi.py b/scripts/qapi.py |index e6d014b..b862ec9 100644 |--- a/scripts/qapi.py |+++ b/scripts/qapi.py |@@ -1570,6 +1570,7 @@ const char *const %(c_name)s_lookup[] = { | max_index = c_enum_const(name, 'MAX', prefix) | ret += mcgen(''' | [%(max_index)s] = NULL, |+// %(max_index)s | }; | ''', | max_index=max_index) then running: $ cat qapi-{types,event}.c tests/test-qapi-types.c | sed -n 's,^// \(.*\)MAX,s|\1MAX|\1_MAX|g,p' > list $ git grep -l _MAX | xargs sed -i -f list The only things not generated are the changes in scripts/qapi.py.

2015-11-26Revert "exec: silence hugetlbfs warning under qtest"Daniel P. Berrange1-14/+14
This reverts commit 1c7ba94a184df1eddd589d5400d879568d3e5d08. That commit changed QEMU initialization order from - object-initial, chardev, qtest, object-late to - chardev, qtest, object-initial, object-late This breaks chardev setups which need to rely on objects having been created. For example, when chardevs use TLS encryption in the future, they need to have tls credential objects created first. This revert, restores the ordering introduced in commit f08f9271bfe3f19a5eb3d7a2f48532065304d5c8 Author: Daniel P.

vhost-user-test prints a warning. A test should not need to run on hugetlbfs, let's silence the warning under qtest. The condition can't check on qtest_enabled() since vhost-user-test actually doesn't use qtest accel. However, qtest_driver() can be used, if qtest_init() is called early enough. For that reason, move chardev and qtest initialization early. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.

This filter is to buffer/release packets. Can be used when using MicroCheckpointing or other Remus like VM FT solutions. You can also use it to crudely simulate network delay. Doesn't actually delay individual packets, but batches them together, which is a delay of sorts. Usage: -netdev tap,id=bn0 -object filter-buffer,id=f0,netdev=bn0,queue=rx,interval=1000 NOTE: Interval is in microseconds, it can't be omitted currently, and can't be 0.

2015-07-07migration: create new section to store global stateJuan Quintela1-0/+1
This includes a new section that for now just stores the current qemu state. Right now, there are only one way to control what is the state of the target after migration. - If you run the target qemu with -S, it would start stopped. - If you run the target qemu without -S, it would run just after migration finishes. The problem here is what happens if we start the target without -S and there happens one error during migration that puts current state as -EIO. Migration would ends (notice that the error happend doing block IO, network IO, i.e. nothing related with migration), and when migration finish, we would just "continue" running on destination, probably hanging the guest/corruption data, whatever.
