We generate a static visit_type_FOO_fields() for every type FOO. However, sometimes we need a forward declaration. Split the code to generate the forward declaration out of gen_visit_implicit_struct() into a new gen_visit_fields_decl(), and also prepare for a forward declaration to be emitted during gen_visit_struct(), so that a future patch can switch from using visit_type_FOO_implicit() to the simpler visit_type_FOO_fields() as part of unboxing the base class of a struct. No change to generated code. Signed-off-by: NEric Blake <eblake@redhat.com> Message-Id: <1445898903-12082-8-git-send-email-eblake@redhat.com> Signed-off-by: NMarkus Armbruster <armbru@redhat.com>

A future qapi patch will rework generated structs with a base class to be unboxed. In preparation for that, change the code that allocates then populates an info struct to instead merely populate the fields of an info field passed in as a parameter (renaming vnc_basic_info_get* to vnc_init_basic_info*). Add rudimentary Error handling at the lowest levels for cases where the old code returned NULL; but rather than plumb Error all the way through the stack, the callers drop the error and return NULL as before.

c_name() produces names starting with 'q_' when protecting a dictionary member name that would fail to directly compile, but in doing so can cause clashes with any member name already beginning with 'q-' or 'q_'. Likewise, we create a C name 'has_' for any optional member that can clash with any member name beginning with 'has-' or 'has_'. Technically, rather than blindly reserving the namespace, we could try to complain about user names only when an actual collision occurs, or even teach c_name() how to munge names to avoid collisions. But it is not trivial, especially when collisions can occur across multiple types (such as via inheritance or flat unions). Besides, no existing .json files are trying to use these names. So it's easier to just outright forbid the potential for collision. We can always relax things in the future if a real need arises for QMP to express member names that have been forbidden here. 'has_' only has to be reserved for struct/union member names, while 'q_' is reserved everywhere (matching the fact that only members can be optional, while we use c_name() for munging both members and entities). Note that we could relax 'q_' restrictions on entities independently from member names; for example, c_name('qmp_' + 'unix') would result in a different function name than our current 'qmp_' + c_name('unix'). Update and add tests to cover the new error messages.

Type names ending in 'List' can clash with qapi list types in generated C. We don't currently use such names. It is easier to outlaw them now than to worry about how to resolve such a clash in the future. For precedence, see commit 4dc2e690, which did the same for names ending in 'Kind' versus implicit enum types for qapi unions. Update the testsuite to match.

We were using regular expressions to see if ret included any earlier text that emitted a 'goto out;' line, to decide whether we needed to output an 'out:' label. But this is fragile, if the ret text can possibly combine more than one generated function body, where the first function used a goto but the second does not. Change the code to just check for the known conditions which cause an error check to be needed. Besides, it's slightly more efficient to use plain checks than regular expression searching.

Add some testsuite coverage to ensure future patches are on the right track: Our current C representation of qapi arrays is done by appending 'List' to the element name; but we are not preventing the creation of an object type with the same name. Add reserved-type-list.json to test this. Then rename enum-union-clash.json to reserved-type-kind.json to cover the reservation that we DO detect, and shorten it to match the fact that the name is reserved even if there is no clash. We are failing to detect a collision between a dictionary member and the implicit 'has_*' flag for another optional member. The easiest fix would be for a future patch to reserve the entire "has[-_]" namespace for member names (the collision is also possible for branch names within flat unions, but only as long as branch names can collide with (non-variant) members; however, since future patches are about to remove that, it is not worth testing here). Add reserved-member-has.json to test this. A similar collision exists between a dictionary member where c_name() munges what might otherwise be a reserved name to start with 'q_', and another member explicitly starts with "q[-_]". Again, the easiest solution for a future patch will be reserving the entire namespace, but here for commands as well as members. Add reserved-member-q.json and reserved-command-q.json to test this; separate tests since arguably our munging of command 'unix' to 'qmp_q_unix()' could be done without a q_, which is different than the munging of a member 'unix' to 'foo.q_unix'. Finally, our testsuite does not have any compilation coverage of struct inheritance with empty qapi structs. Update qapi-schema-test.json to test this. Note that there is currently no technical reason to forbid type name patterns from member names, or member name patterns from types, since the two are not in the same namespace in C and won't collide; but it's not worth adding positive tests of these corner cases at this time, especially while there is other churn pending in patches that rearrange which collisions actually happen.

VSERPORT_CHANGE is emitted when the guest opens or closes a virtio-serial port. The event's member "id" identifies the port. When several events arrive quickly, throttling drops all but the last of them. Because of that, a QMP client must assume that *any* port may have changed state when it receives a VSERPORT_CHANGE event and throttling may have happened. Make the event more useful by throttling it for each port separately.

In Release 6, the behaviour of WAIT has been modified to make it a requirement that a processor that has disabled operation as a result of executing a WAIT will resume operation on arrival of an interrupt even if interrupts are not enabled. Signed-off-by: NLeon Alrae <leon.alrae@imgtec.com>

We don't actually care for the scale, so we can just as well use the simpler interface. Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Message-Id: <1444921716-9511-4-git-send-email-armbru@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com>

The event throttling state machine is hard to understand. I'm not sure it's entirely correct. Rewrite it in a more straightforward manner: State 1: No event sent recently (less than evconf->rate ns ago) Invariant: evstate->timer is not pending, evstate->qdict is null On event: send event, arm timer, goto state 2 State 2: Event sent recently, no additional event being delayed Invariant: evstate->timer is pending, evstate->qdict is null On event: store it in evstate->qdict, goto state 3 On timer: goto state 1 State 3: Event sent recently, additional event being delayed Invariant: evstate->timer is pending, evstate->qdict is non-null On event: store it in evstate->qdict, goto state 3 On timer: send evstate->qdict, clear evstate->qdict, arm timer, goto state 2 Signed-off-by: NMarkus Armbruster <armbru@redhat.com> Message-Id: <1444921716-9511-3-git-send-email-armbru@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com>
