2022-05-08Pass matrixType(QString), not Event::Type, to basicJson()Alexey Rusakov
Not that it was very important, as the two are basically the same thing (and matrixTypeId() is about to be obsoleted); but formally basicJson() is supposed to get the former, not the latter.
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).
2022-05-08Event content: provide toJson() instead of deriving from EC::BaseAlexey Rusakov
EventContent::Base has been made primarily for the sake of dynamic polymorphism needed within RoomMessageEvent content (arguably, it might not be really needed even there, but that's a bigger matter for another time). When that polymorphism is not needed, it's easier for reading and maintenance to have toJson() member function (or even specialise JsonConverter<> outside of the content structure) instead of deriving from EC::Base and then still having fillJson() member function. This commit removes EventContent::Base dependency where it's not beneficial.
2022-05-08Simplify EventContent a bitAlexey Rusakov
Main changes: 1. Base::fillJson() gets a QJsonObject& instead of QJsonObject* - c'mon, there's nothing inherently wrong with using an lvalue reference for a read-write parameter. 2. UrlWithThumbnailContent merged into UrlBasedContent. The original UrlBasedContent was only used to produce a single class, AudioContent, and even that can logically have a thumbnail even if the spec doesn't provision that. And there's no guarantee even for visual content (ImageContent, e.g.) to have thumbnail data; the fallback is already tested. 3. toInfoJson is converted from a template to a couple of overloads that supersede fillInfoJson() member functions in FileInfo/ImageInfo. These overloads are easier on the eye; and clang-tidy no more warns about ImageInfo::fillInfoJson() shadowing FileInfo::fillInfoJson(). 4. Now that UrlWithThumbnail is gone, PlayableContent can directly derive from UrlBasedContent since both its specialisations use it. 5. Instead of FileInfo/ImageInfo, fillInfoJson() has been reinvented within UrlBasedContent so that, in particular, PlayableContent wouldn't need to extract 'info' subobject and then roll it back inside the content JSON object.

2022-05-08StateEvent: use non-member JSON convertersAlexey Rusakov
With the reworked JsonConverter code it is possible to work uniformly with structures that have a member toJson() and a constructor converting from QJsonObject, as well as with structures that rely on an external JsonConverter specialisation.
2022-05-08toSnakeCase and EventContent::SingleKeyValueAlexey Rusakov
This is a rework of EventContent::SimpleContent previously defined in simplestateevents.h. Quite a few events (and not only state events) have just a single key-value pair in their content - this structure (which is really just a template wrapper around the value) and the accompanying JsonConverter<> specialisation encapsulate the concept to streamline definition of such events. This commit only has simplestateevents.h using it; further commits will use SingleKeyValue in other places. toSnakeCase is a facility function that converts camelCase used for C++ variables into snake_case used in JSON payloads. Combined with the preprocessor trick that makes a string literal from an identifier, this allows to reduce boilerplate code that repeats the same name for fields in C++ event classes and fields in JSON. SingleKeyValue uses it, and there are other cases for it coming.

2022-02-26Handle to-device messages before handling roomdataTobias Fella
Probably improves the performance slightly If we handle to room data first, if a message arrives at the same time as the to-device message containing the key and we handle the message first, it will not be decryptable and stored as undecrypted. Then, when the key is handled, the cache of undecrypted messages is searched, the message decrypted and replaced. When handling the key first, the message can be decryped instantly.
