2022-09-04StateEventBase -> StateEventAlexey Rusakov
Now that StateEvent name is vacated, the naming for event core classes can be completely unified: Event, RoomEvent, CallEvent, StateEvent.
2022-09-04CallEventBase -> CallEvent; pack up all call eventsAlexey Rusakov
These are small enough to comfortably reside in a single translation unit.
2022-09-04Streamline event typesAlexey Rusakov
This commit introduces a few things to further reduce the boilerplate across event type definitions: - Event type is no more separately stored in Event and therefore no more passed to base event constructors. Until the previous commit, it was used by is() to quickly match the event type; with the new event metatype class, the same is achieved even quicker by comparing metatype pointers. - EventTemplate is a generalisation of StateEvent for all event types providing common constructor signatures and content() for (most) leaf event types. StateEvent therefore has become a partial specialisation of EventTemplate for types derived from StateEventBase; as the known client code base does not use it directly, a compatibility alias is not provided. Also, DEFINE_SIMPLE_EVENT now expands into a class deriving from EventTemplate. - On top of StateEvent->EventTemplate specialisation, KeyedStateEventBase and KeylessStateEventBase types are introduced with appropriate constructor signatures (with or without state_key, respectively) to allow `using` of them from derived event types. To facilitate writing of constraints, concepts for keyed and keyless state event types are also introduced; RoomStateView, e.g., makes use of those to provide appropriate method signatures. - typeId(), unknownEventTypeId(), UnknownEventTypeId are no more provided - they weren't used throughout the known code base (Quaternion, NeoChat), and the concept of "unknown event types" is hereby eliminated entirely. - RoomKeyEvent no more accepts senderId as a parameter; it has never been a good practice as the sender is assigned by Connection anyway.
2022-09-04EventMetaType, QUO_EVENT, QUO_BASE_EVENTAlexey Rusakov
The new metatype framework replaces EventFactory/DEFINE_EVENT_TYPEID/REGISTER_EVENT_TYPE; it is faster, more functional and extensible. Of note: - EventMetaType mostly reproduces the logic of EventFactory but supports custom base event types not just for loading (that part EventFactory also supported) but also for matching - previously you had to have Event::is*Event() for base type matching. Now Quotient::is() can match against both base and leaf types. - Instead of DEFINE_EVENT_TYPEID and REGISTER_EVENT_TYPE there's now a single macro, QUO_EVENT, intended for use in the way similar to Q_OBJECT. Actually, the entire framework borrows heavily from QMetaObject and Q_OBJECT. Making event types full-fledged QObjects is still not considered because half of QObject functions would not be applicable (e.g. signals/slots) while another half (in particular, using Matrix type ids to select event types) would still have to be done on top of QObject. And QML can just access events as const QJsonObjects which is arguably more lightweight as well. - QUO_BASE_EVENT is a new macro replacing EventFactory object definitions. This was necessary for the same reason why Q_OBJECT is a macro: aside from a static object definition, this macro introduces a virtual function override to resolve the metatype at runtime. This very mechanism is used to make event type matching/casting as quick as possible - QUO_BASE_EVENT and QUO_EVENT use the C++20 __VA_OPT__ feature that is only available with the new MSVC preprocessor (see https://docs.microsoft.com/en-us/cpp/preprocessor/preprocessor-experimental-overview); the respective switch was added to CMakeLists.txt.
2022-05-08basic*EventJson() -> *Event::basicJson()Alexey Rusakov
This makes it easier and more intuitive to build a minimal JSON payload for a given event type. A common basicJson() call point is also convenient in template contexts (see next commits).
2021-12-29Use QLatin1String for event typeId'sAlexey Rusakov
Before all, this fixes the problem with double-initialising of type ids; it could have been fixed with a smaller change but EventTypeRegistry is fairly superfluous now when inline variables are a thing and it's possible to have an extensible registry system using literally pointers to the memory that are guaranteed to be unique. That being said, event_type_t is still QLatin1String and not a bare const char* (or void*), mostly to stay on the safe side when it comes to type identities: unlike const char*, QLatin1String's are deep-compared, meaning that matching for switchOnType (former visit) occurs a bit slower now. This may change in the future; but this is the first step in getting rid of EventTypeRegistry. This change means that initializeTypeId is no more needed; also, two static member functions, typeId() and matrixTypeId(), are being replaced with a single inline static member variable, TypeId. This commit doesn't apply that transition across the event types, meaning that you'll get a pile of warnings when compiling the library. These warnings will be tackled in further commits within this branch.
2021-12-29Refactor EventFactory and move it out of _impl::Alexey Rusakov
Strictly speaking, EventFactory can be further instantiated if any client application figures they need a whole new base class for events and respectively a separate EventFactory specialisation for it. Where this whole commit started though was a linkage error because I did not plan to expose Quotient-specific logging categories for linkage (effectively, usage) from the client code - meanwhile the inline code of EventFactory uses qDebug(EVENTS), meaning I had to either add QUOTIENT_API to EVENTS or hide those invocations. This in turn led to trimming the EventFactory constructor back to trivial implementation and dropping the guard variable that was supposed to trace duplicate EventFactory<BaseEventT> objects for the same BaseEventT - with the reasoning that such situation is not really dangerous (unlike EventTypeRegistry double-initialisation fiasco, see #413), and at the same time it can be easily detected in the logs by duplicated factory method registration messages. And while I was at it, I replaced the meaningless bool in the return type of EventFactory<>::addMethod with the slightly more (but still barely) useful reference to the inserted factory method. One can (in theory) use it now if they need to turn some event JSON into an object of some specific event type or nullptr if the event type in the JSON payload doesn't match - but at the same rate (for now at least) one can call makeIfMatches<EventT>() directly. With this commit, both Quotest and Quaternion build and link using either Clang or GCC even under -fvisibility=hidden. However, running quotest now reproduces #413, which is a matter of event typeId infrastructure refactoring, coming in further commits.
2021-11-28Comment on const return types in event.hAlexey Rusakov
Proper linters recognise that the returned types are not primitive, while people might still be confused a bit.
2021-11-26Revert "Drop #include "logging.h" from event.h"Alexey Rusakov
Doesn't really help build times, instead breaking the build on older Qt.
2021-11-26Drop #include "logging.h" from event.hAlexey Rusakov
Makes compilation a tad lighter.
2021-01-16Updated copyright statements upon Git auditKitsune Ral
After going through all the files and the history of commits on them it was clear that some copyright statements are obsolete (the code has been overwritten since) and some are missing. This commit tries best to remedy that, along with adding SPDX tags where they were still not used. Also, a minimal SPDX convention is documented for further contributions. Closes #426.

2018-07-04Event types system remade to be extensibleKitsune Ral
There were two common points that had to be updated every time a new event is introduced: the EventType enumeration and one of 3 doMakeEvent<> specialisations. The new code has a template class, EventFactory<>, that uses a list of static factory methods to create events instead of typelists used in doMakeEvent<>(); the EventType enumeration is replaced with a namespace populated with constants as necessary. In general, EventType is considered a deprecated mechanism altogether; instead, a set of facilities is provided: is<>() to check if an event has a certain type (to replace comparison against an EventType value) and visit<>() to execute actions based on the event type (replacing switch statements over EventType values). Closes #129.

The latter one causes linkage errors when used from a template method (but not from a template class, puzzlingly).
2018-05-03GetRoomEventsJob (replaces RoomMessagesJob) + refactoringKitsune Ral
1. Updates in this commit (see further) allow to generate and build GetRoomEventsJob from message_pagination.yaml; this job completely preempts RoomMessagesJob. 2. EventsBatch<> is no more a thing; there's EventsArray<> to replace it but it's loaded from a JSON array rather than an event batch (a JSON array inside another JSON object). SyncJob that used it extensively has been moved to "conventional" containers (Events, RoomEvents and the newly introduced StateEvents). RoomMessagesJob that also used EventsBatch<> is decommissioned (see above). 3. RoomEventsRange is now an alias for Range<RoomEvents>, defined in util.h (otherwise almost the same). 4. Connection::getMessages() is no more. Use Room::getPreviousContent() and Connection::callApi<GetRooMEventsJob>() instead. 5. Moving things around in Room, since SyncJob now supplies state events in more specific StateEvents, rather than RoomEvents.

It's been long overdue to separate them from the rest of the stuff (docs etc.). Also, this allows installing to a directory within the checked out git tree (say, ./install/, similar to ./build/).
