2022-01-21Redo EventRelation; deprecate RelatesToAlexey Rusakov
RelatesTo and EventRelation have been two means to the same end in two different contexts. (Modernised) EventRelation is the one used now both for ReactionEvent and EventContent::TextContent. The modernisation mostly boils down to using inline variables instead of functions to return relation types and switching to QLatin1String from const char* (because we know exactly that those constants are Latin-1 and QLatin1String is more efficient than const char* to compare/convert to QString).
2022-01-18Don't use 'static' on top-level/namespace scopeAlexey Rusakov
When internal linkage is necessary, anonymous namespaces fulfil the same purpose in a better way. See also: https://stackoverflow.com/questions/4422507/superiority-of-unnamed-namespace-over-static
2022-01-18Move over non-interface code to QLatin1StringAlexey Rusakov
It's better than const char* because any interaction between const char* and QString assumes that const char* contains UTF-8, which is pessimistic and therefore inefficient; at the same time: - construction of QString from QLatin1String is extremely fast (boiling down to padding null bytes) - "something"_ls is much shorter than QStringLiteral("something") - "something"_ls produces a direct pointer to the literal at compile time, using the benefits of raw string literals (deduplication, e.g.) The library API will also transition to QLatin1String where applicable, likely in 0.8.
2022-01-18Revise inline keyword usageAlexey Rusakov
- Templates and constexpr imply inline - A function called from a single site better be inlined.
2022-01-05DEFINE_EVENT_TYPEID: fix up deprecation warningsAlexey Rusakov
2022-01-05Make TagRecord generally betterAlexey Rusakov
It doesn't need all those things inside - order_type alias is no more in use; operator<() is better outside; QLatin1String is better to compare against than const char* (because const char* is assumed to be UTF-8); and TagRecord is really small so it doesn't need const& for parameters.

Those are already inherited with 'using'.

2022-01-01Don't use QUOTIENT_API inside REGISTER_EVENT_TYPEAlexey Rusakov
On Windows QUOTIENT_API expands to different things depending on whether the library is built or used. This results in confusing statements (and MSVC erroring out on them, in some cases - see below - quite legitimately) not only when the application includes Quotient headers but also when the application defines custom events and uses REGISTER_EVENT_TYPE to make them creatable from /sync responses. To avoid repeated registration when dynamic linking is involved, EventFactory<>::addMethod() now bluntly looks up the method for this type in the vector of already registered methods. It would surely be quicker to use a static variable instead; but since the refreshed API for addMethod returns a reference to the factory method it's necessary to do this lookup anyway. Once the primary goal of this branch is achieved across platforms I might experiment with lighter ways to register factory methods; for now here's a minimal change to make the code build on Windows.

Thanks to Sonar for reminding that constexpr implies inline.

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.
2021-12-29Add QUOTIENT_API throughout non-generated codeAlexey Rusakov
This include all (hopefully) classes/structures and functions that have non-inline definitions, as well as namespaces with Q_NAMESPACE since those have non-inline (as of Qt 5.15) QMetaObject - for that a new macro, QUO_NAMESPACE, has been devised to accommodate the lack of Q_NAMESPACE_EXPORT in Qt before 5.14.

This is a leftover from deferred `name` initialisation that wasn't needed in the end.

2021-12-22StateEventBase: force type to unknown if stateKey is not in JSONAlexey Rusakov
2021-12-22Simplify the code around EventFactory<>Alexey Rusakov
The former code assumed that EventFactory<> is just a class-level shell for a bunch of functions and a static data member that only exists to allow specialisations to occur for the whole group together. On top of that, setupFactory() and registerEventType() strived to protect this group from double registration coming from static variables in an anonymous namespace produced by REGISTER_EVENT_TYPE. The whole thing is now de-static-ed: resolving the factory now relies on class-static Event/RoomEvent/StateEventBase::factory variables instead of factory_t type aliases; and REGISTER_EVENT_TYPE produces non-static inline variables instead, obviating the need of registerEventType/setupFactory kludge.
2021-12-21Don't chain RoomEvent to Event factory any moreAlexey Rusakov
Objects derived from Event are not room events (in the spec sense) and never occur in the same arrays as room events; therefore this chaining has always been superfluous.

Also, RoomAliasesEvent is to be completely gone after 0.7.
2021-12-02Improve function_traits<>; split out from util.*Alexey Rusakov
Quotient::function_traits<> did not support member functions in a proper way (i.e. the way std::invoke_result<> treats them, with the function's owning class represented as the first parameter). Now that I gained the skill and understanding in function_traits<> somewhat wicked machinery, I could properly support member functions. Overloads and generic lambdas are not supported but maybe we'll get to those one day.
2021-12-02visit(Event, ...) -> switchOnType()Alexey Rusakov
It has not much to do with the Visitor design pattern; also, std::visit() has different conventions on the order of parameters.

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.
2021-11-28Don't std::move when the callee doesn't support itAlexey Rusakov
In both fixed cases the callee accepts a const reference, which makes std::move() useless. Static analyzers apparently missed them because the cases are inside a macro.
2021-11-28Event::unsignedPart()Alexey Rusakov
Similar to contentPart() - apparently there are enough places across the code that would benefit from it.
2021-11-27basicEventJson(): dismiss with the templateAlexey Rusakov
Given that QJsonObject only accepts QStrings in the list constructor, the template is useless cruft.
2021-11-27Event::content() -> contentPart()Alexey Rusakov
There's a clash between Event::content() (a template function) and RoomMessageEvent::content() (plain member). Out of these two, the name more fits to the RME's member function - strictly speaking, Event::content() retrieves a part of content, and so is renamed. In addition, contentPart() defaults to QJsonValue now, which is pretty intuitive (the function returns values from a JSON object) and allows to implement more elaborate logic such as if (const auto v = contentPart<>("key"_ls); v.isObject()) { // foo } else if (v.isString()) { // bar } else { // boo }
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.
2021-11-26Event: deprecate originalJson[Object]()Alexey Rusakov
The "original JSON" wording is misleading: the returned JSON can be and is routinely edited as a part of event construction, redaction, editing. Also, originalJson() name is misleading in that it returns a stringified (in a very specific way) JSON and not an object. You have to call fullJson() to get the object, and originalJsonObject(), confusingly, returns exactly the same thing but as a value rather than as a reference. The original intention of keeping originalJsonObject() was to make it Q_INVOKABLE or use it as an accessor for a Q_PROPERTY. unfortunately, this was never really practical as discussed in the previous commit. All that implies that clients have to handle passing event JSON to QML themselves, in the form they prefer (as an object or a string). The added complexity is negligible though; on the other hand, there's added flexibility in, e.g., choosing a compact instead of default JSON layout or even generate a highlighted JSON representation.
2021-11-26Drop #include "logging.h" from event.hAlexey Rusakov
Makes compilation a tad lighter.
2021-11-26Drop Q_GADGET from most uncopyable classes; other minor cleanupAlexey Rusakov
Q_GADGET is generally used to enable two things outside of QObject: Q_PROPERTY/Q_INVOKABLE and Q_ENUM/Q_FLAG. While the latter can be used in its own right in QML, the former requires Q_GADGET instances to be passed to QML by value, which is not really possible with uncopyable/unassignable classes. Bottom line is that Q_PROPERTY in anything derived from Quotient::Event is not viable, making Q_GADGET macro useless unless there's a Q_ENUM/Q_FLAG (as is the case with RoomMessageEvent, e.g.).

2021-11-08Q_DISABLE_MOVE/COPY_MOVE; QT_IGNORE_DEPRECATIONSAlexey Rusakov
DISABLE_MOVE is no more; instead, the library provides Q_DISABLE_MOVE (and also Q_DISABLE_COPY_MOVE while at it) for Qt pre-5.13 that don't have it yet. Same for QT_IGNORE_DEPRECATIONS - it only arrived in 5.15 but all the building pieces existed prior so libQuotient has it regardless of the Qt version used for building.
