2022-05-29Move some Meg/Olm session logic from Room::Private to Connection::PrivateAlexey Rusakov
Functions (Room::Private::)createOlmSession, payloadForUserDevice and sendRoomKeyToDevices don't have a lot to do with the given Room object but deal with quite a few things stored in Connection. This commit moves them to Connection::Private, exposing sendSessionKeyToDevices (the new name for sendRoomKeyToDevices) in Connection so that Room could call it from Room::P::sendMegolmSession(). While moving these over, a few additional things were adjusted: - more functions marked as const - a few functions could be moved now from Connection to Connection::Private - false slots in Connection (such as picklingMode) are moved out of the slots block - keys.yml in Matrix CS API definitions has been adjusted to match the real structure of `/claim` response (see quotient-im/matrix-spec repo); csapi/keys.h has been regenerated accordingly.
2022-05-29Refactor creation of Megolm sessions in RoomAlexey Rusakov
Notably, replace a multi-level hash map with QMultiHash and factor out Room::P::createOlmSession().

2022-05-16QOlmExpected and associated refactoringAlexey Rusakov
As mentioned in the commit introducing `Expected`, `QOlmExpected` is simply an alias for `Expected<T, QOlmError>`. This simplifies quite a few function signatures in `QOlm*` classes and collapses unwieldy `std::holds_alternative<>`/`std::get<>` constructs into a neat contextual bool cast and an invocation of `operator*` or `value()`/`error()` accessors that don't need to specify the type. While refactoring the code, I found a couple of cases of mismatching `uint32_t` and `qint32_t` in return values; a couple of cases where `decrypt()` returns `QString` which is in fact `QByteArray` (e.g., in `QOlmSession::decrypt()`); there's a repetitive algorithm in `Connection::Private::sessionDecryptPrekey()` and `sessionDecryptGeneral()`
2022-05-16Simplify QOlmSession::matchesInboundSession*()Alexey Rusakov
There's no particular use in letting `QOlmError` out, only to confirm that, well, `QOlmError` is just another form of no-match.
2022-05-16QOlmAccount::needsSave() shouldn't be constAlexey Rusakov
Making Qt signals const is an impossible commitment - once the signal is out, you can't control if any called slot will change the emitting class or not. The code compiles but const-ness is not preserved.

2022-05-14Cleanup across the boardAlexey Rusakov
Mainly driven by clang-tidy and SonarCloud warnings (sadly, SonarCloud doesn't store historical reports so no link can be provided here).
2022-04-23SLICE()Alexey Rusakov
Add a macro to make slicing clear in the code and quiet for static analysis.

2022-02-26Use QOlmMessage::Type in more placesTobias Fella
Make sure that the enum values correspond to the values used in the spec and use them instead of magic constants
2022-02-16isSupportedAlgorithm()Alexey Rusakov
That's a better primitive than just exposing SupportedAlgorithms list.
2022-02-16Use QHash instead of QMapAlexey Rusakov
We don't seem to need sorted associative containers in those cases.
2022-02-16CleanupAlexey Rusakov
A note on switching to QLatin1String for JSON key constants - this is more concise and barely affects (if at all) runtime performance (padding each QChar with zeros is trivial for assignment; and comparison can be done directly with the same performance as for two QStrings).
2022-02-16Add a few missing QUOTIENT_API stanzasAlexey Rusakov
Also, removed Q_GADGET macros from key verification events as those don't seem to do anything (no Q_ENUM/Q_FLAG things, namely).
