2022-06-17Make Connection::sendToDevices() an actual slotAlexey Rusakov
Although Qt 5 didn't complain about that, you could never really use sendToDevices() in its slot (or even invocable) capacity because Qt's meta-type system could not handle move-only UsersToDevicesToEvents. Qt 6 is more stringent; the build fails at trying to instantiate QMetaType for that type (with a rather unhelpful error message thrown by Clang, and more helpful but very verbose diagnostic from MSVC) because it does not provide a copy constructor. However, sendToDevice doesn't really need to have full-blown events in that parameter; just the content of the event is equally fine. This commit does exactly that: replaces UsersToDevicesToEvents with UsersToDevicesToContent that contains QJsonObject's instead of EventPtr's. The code around is updated accordingly. Also: factor out the key event JSON creation from makeMessageEventForSessionKey() because it's the same JSON for each target device; the function therefore is called encryptSessionKeyEvent() now.
2022-06-11Regenerate API files using latest matrix-specAlexey Rusakov
New: - refresh tokens support (changes in login.* and registration.*; RefreshJob); - GetRelatingEvents[WithRelType[AndEventType]]Job Changed space_hierarchy.*: - childrenState is of type StateEvents now; limit and maxDepth are (omittable) integers, not doubles. - no more unused `stripped_state.h` file inclusion.

The latest GTAD no more emits public_rooms_chunk.h (public_rooms_response.h already has the same definition), and skips on PublicRoomsResponse structure that is never used.
2022-06-08Save connection state while QCoreApplication is still thereAlexey Rusakov
This reimplements #558 in a more reliable way. Deconstruction of AccountRegistry may (or may not, yay for static initialisation) occur after deconstruction of QCoreApplication, in which case an attempt to determine the directory for the state fails because it depends on the application object existence.

2022-05-31Fix Room::getPreviousContent() to match new CS APIAlexey Rusakov
There was a fairly nasty change where `from` parameter in /messages became optional and that led to two QString parameters (`from` and `dir) switching positions. Because they have the same type, the problem only shows at runtime. This commit fixes Room::getPreviousContent() to pass the parameters at right positions; client code won't feel anything (unless it uses GetRoomEventsJob directly).
2022-05-31Tweak QOlmAccount and data structures aroundAlexey Rusakov
This is mainly to plug the definition of a string-to-variant map for one-time keys (see https://spec.matrix.org/v1.2/client-server-api/#key-algorithms) into the CS API generated code (see the "shortcut OneTimeKeys" commit for gtad.yaml); but along with it came considerable streamlining of code in qolmaccount.cpp. Using std::variant to store that map also warranted converters.h to gain support for that type (even wider than toJson() that is already in dev - a non-trivial merge from dev is in order).

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.

2022-05-29Move encryptFile/decryptFile out of EncryptedFileMetadataAlexey Rusakov
These are not operations on EncryptedFileMetadata but rather on a combination of EncryptedFileMetadata and ciphertext. If C++ had multimethods these could be bound to such a combination.

2022-05-29Refactor EncryptedFile and EC::FileInfo::fileAlexey Rusakov
Besides having a misleading name (and it goes back to the spec), EncryptedFile under `file` key preempts the `url` (or `thumbnail_url`) string value so only one of the two should exist. This is a case for using std::variant<> - despite its clumsy syntax, it can actually simplify and streamline code when all the necessary bits are in place (such as conversion to JSON and getting the common piece - the URL - out of it). This commit replaces `FileInfo::url` and `FileInfo::file` with a common field `source` of type `FileSourceInfo` that is an alias for a variant type covering both underlying types; and `url()` is reintroduced as a function instead, to allow simplified access to whichever URL is available inside the variant. Oh, and EncryptedFile is EncryptedFileMetadata now, to clarify that it does not represent the file payload itself but rather the data necessary to obtain that payload.

Truncate ciphertext buffer to actual size during file encryption

2022-05-20Truncate ciphertext buffer to actual size during file encryptionTobias Fella
The ciphertext for AES CTR is exactly as large as the plaintext (not necessarily a multiple of the blocksize!). By truncating the ciphertext, we do not send bytes that will be decrypted to gibberish. As a side node, we probably do not need to initialize the ciphertext buffer larger than the plaintext size at all, but the OpenSSL docs are a bit vague about that.
