* QStateMachine: empty the whole internal queue before external queueErik Verbruggen2015-05-191-0/+39
| | | | | | | | | | If the internal queue contained multiple events, but the first one did not select any transitions, the external event queue would be checked before the remaining events in the internal queue.

* QStateMachine: Fix transition ordering.Erik Verbruggen2015-05-071-0/+64
| | | | | | | | | | | | When there are conflicting transitions, a transition that is nested deeper (i.e. more specific) has priority. If two transitions have the same nesting level, the one that comes first in the document order gets priority. Before this patch, only the document order was considered.

* QStateMachine: add internal transitions.Erik Verbruggen2015-05-041-0/+44
| | | | | | | | | | | | | The behavior of "external" and "internal" transitions is identical, except in the case of a transition whose source state is a compound state and whose target(s) is a descendant of the source. In such a case, an internal transition will not exit and re-enter its source state, while an external one will. [ChangeLog][State machine] Added support for internal transitions.

* QStateMachine: cache expensive calculations.Erik Verbruggen2015-05-041-12/+15
| | | | | | | | | | | | | | | | | | As nothing changes in the state machine when selecting transitions for events and then calculating the exit- and entry-sets, some calculations can be cached. The exit set for a transition was calculated multiple times. First in removeConflictingTransitions, where the two loops would each calculate them multiple times. Then secondly in microstep(), which would calculate the exit set for all transitions. Transition selection, exit set calculation, and entry set calculation all calculate the transition domain and effective target states for transitions.

* QStateMachine: remove conflicting transitions after selection.Erik Verbruggen2015-04-101-10/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After selecting all (enabled) transitions for a microstep, filter out any conflicting transition. The actual conflict resulution is done by ordering the transitions in order of the states that selected them. For example: if an event would trigger two transitions in a parallel state where one would exit that state and the other would not, this filtering prevents the state machine from selecting both states (as this case is an invalid state of the whole machine). This also fixes the exit set calculation for parallel states when one of its substates is exited and subsequently re-entered in the same transition. Previously, the parallel state was not exited, and subsequent re-entry was ignored (because it was still active). Now it is correctly exited and re-entered. A side-effect of the transition ordering mentioned above is it also fixes the non-deterministic behavior of which of the conflicting transitions is taken. [ChangeLog][QtCore] Fixed an issue where the state machine could end up in an invalid state when transitions from a parallel state were not checked for conflicts. [ChangeLog][QtCore] Fixed a case where a parallel state was not exited and re-entered when one of its substates was exited and subsequently re-entered.

| | | | | | | | | | | | | | | | | | | | | | | When a history state is entered that has an actual saved history (so not the initial state), the entry set was calculated wrongly in some cases.

| | | | | | | | | | | | | | | | | | | | | Commit f9a17d7f0f02f7af849afdf653a763ffdaf78a1b fixed it for the case where the sender object is in a different thread at transition setup time. However, it still didn't work if either the sender object or the state machine was moved to a different thread at some later time, before the machine was started. Therefore: Bite the sour grape and traverse all the machine's transitions when the machine is being started, registering those signal transitions whose sender objects are in other threads. This will increase the machine's startup time (proportional to the number of transitions), but at least it works in all known scenarios, meaning we don't have to document weird restrictions regarding the order in which the user's operations have to be done.

* statemachine: Fix signal transition handling in multi-threaded setupKent Hansen2012-07-131-0/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default, QStateMachine lazily registers signal transitions (i.e., connects to the signal) when the transition's source state is entered. The connections are established in Qt::AutoConnection mode, which means that if the sender object lives in a different thread, the signal processing will be queued. But if a sender object's signal is used in an out-going transition of the target state of the queued transition, it's possible that a second signal emission on the sender object's thread will be "missed" by the state machine; before the machine gets around to processing the first queued emission (and registering the transitions of the new state), a sender object on the other thread could have emitted a new signal. The solution employed here is to eagerly register any signal transition whose sender object is on a different thread; that is, register it regardless of whether the transition's source state is active. Conversely, when a machine's transitions are unregistered (i.e., because the machine finished), signal transitions with sender objects on other threads should be left as-is, in case the machine will be run again. This doesn't solve the case where the sender object is moved to a different thread _after_ the transition has been initialized. Theoretically, we could catch that by installing an event filter on every sender object and handle the ThreadChange events, but that would be very expensive, and likely useless in most cases. So let's just say that that case isn't supported for now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the old implementation, property assignments (QState::assignProperty()) were "second-class citizens". Assignments were not really integrated into the state machine algorithm, but rather done as a separate step (QStateMachinePrivate::applyProperties()). While that was convenient for SCXML spec transcription purposes, it resulted in some pretty poor semantics on the user side: * Properties were not assigned until _after_ both the QAbstractState::onEntry() function had been called and the QState::entered() signal had been emitted. * Automatic property restoration (QStateMachine::RestoreProperties) did not play nice with nested states (and parallel states, in particular). The proper fix is to refactor the implementation to make property assignments first-class in the core state machine algorithm (QStateMachinePrivate::microstep()). In practice, this meant splitting some steps. Instead of calling exitStates() straight away, we now first only compute the states to exit (without actually exiting them), and use the resulting set to compute which properties are candidates for restoration. Similarly, instead of calling enterStates(), we first only compute the states to enter (without actually entering them), and use the resulting set to compute which properties are assigned by the entered states. With that in place, the rest was a matter of moving the various chunks of the old applyProperties() logic to the place where they belong in the per-state entry/exit. All existing autotests pass. Added several tests that verify the desired semantics in more detail.

* statemachine: Make delayed event posting work from secondary threadKent Hansen2012-06-061-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | postDelayedEvent() and cancelDelayedEvent() are marked as thread-safe in the documentation. Unfortunately, they didn't actually work when called from another thread; they just produced some warnings: QObject::startTimer: timers cannot be started from another thread QObject::killTimer: timers cannot be stopped from another thread As the warnings indicate, the issue was that postDelayedEvent() (cancelDelayedEvent()) unconditionally called QObject::startTimer() (stopTimer()), i.e. without considering which thread the function was called from. If the function is called from a different thread, the actual starting/stopping of the associated timer is now done from the correct thread, by asynchronously calling a private slot on the state machine. This also means that the raw timer id can no longer be used as the id of the delayed event, since a valid event id must be returned before the timer has started. The state machine now manages those ids itself (using a QFreeList, just like startTimer() and killTimer() do), and also keeps a mapping from timer id to event id once the timer has been started. This is inherently more complex than before, but at least the API should work as advertised/intended now.

* Enter initial state before QStateMachine::started() is emittedKent Hansen2012-06-041-0/+18
| | | | | | | | | | | | | | | The documentation says that started() "is emitted when the state machine has entered its initial state", but the implementation didn't adhere to that. The consequence is that if you e.g. emitted a signal from a slot connected to started(), and that signal was used by a transition from the initial state, the signal would effectively get ignored and the state machine would remain in the initial state.

* Fix typos in QState sorting functionsKent Hansen2012-06-041-2/+17
| | | | | | | | | | | | | | A QObject can't be a child of itself, so the comparison always returned false. In practice, this was causing the entry/exit order of parallel states to be random. QObject::children() is documented to contain the children in the order in which they were added, so this fix actually achieves deterministic behavior.
