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.
2022-05-29Move 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.

Notably, replace a multi-level hash map with QMultiHash and factor out Room::P::createOlmSession().

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.

2022-01-23Omittable: split out from util.h and refreshAlexey Rusakov
Improvements: - Quotient::lift() - a way to invoke a function on an optional (including Omittable) or a pointer if it's 'truthy'. Doesn't need enhanced function_traits<>, only the standard library; works on any number of arguments that can be dereferenced and casted to bool. - then() - the version of lift() as a member function. - edit() was renamed to ensure() (edit() might become a read-write counterpart of then() at some point). It's not really used across libQuotient codebase (or elsewhere) but is staying there just in case. It can also accept an initializer, removing the requirement of default-constructibility. - Quotient::merge() is simplified, with one universal implementation covering both Omittable/optional and plain values. - All that now lives in its dedicated pair of files, further decluttering util.h
2022-01-06Brush up SsoSession; document Connection::prepareForSsoAlexey Rusakov
Although parented to Connection, SsoSession was pretty leaky in that unsuccessful login attempts didn't delete the object and in some errors didn't even close the local HTTP socket (though new connections would no more be accepted). Also, without the documentation it wasn't clear who owns the object returned by Connection::prepareForSso(). Now it is. Unfortunately, it's not easy to cover SsoSession with tests. Basically, it takes a homeserver and a mock "SSO agent" that would check the SSO URL for validity and then both send the login authorisation to the homeserver as well as ping the callback given by SsoSession. Maybe for another time.
2022-01-02Add ImplPtr and makeImplAlexey Rusakov
The original (more complex and comprehensive) solution belongs to https://oliora.github.io/2015/12/29/pimpl-and-rule-of-zero.html - this commit only provides a small wrapper for non-copyable Private class implementations common throughout libQuotient. Unlike the original, default initialisation is made explicit - you have to pass ZeroImpl<Private>() instead (and I firmly believe it's a good thing: normally pointers to Private should not remain nullptr). The reason ZeroImpl<> is not a template variable is quite simple: unique_ptr is non-copyable and so cannot be initialised from; while a template function will initialise the value in-place thanks to copy elision.

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.

The query is easier to manipulate; and the original mxc URL is not used for the real network request anyway.

2021-07-18MembershipType -> Membership, also used for JoinStateAlexey Rusakov
Instead of being defined independently, JoinState now uses values from the Membership enumeration (former MemberEventContent::MembershipType) that was moved to quotient_common.h for that purpose. Both enumerations gained a Q_FLAG_NS decoration and operator<< overrides that strip "Quotient::" prefix when dumping member/join state values to the log - obviating toCString(JoinState) along the way. Quotient::MembershipType alias is deprecated from now.

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.

2020-12-28Connection: refactor the resolve/login codeKitsune Ral
1. resolveServer() now emits homeserverChanged() even when there's no .well-known file found. 2. checkAndConnect() entirely removed from the header file. 3. Sunny-day scenario for assumeIdentity() is now asynchronous, triggering a call to /whoami to double-check the user. 4. LoginFlow aliases is moved out from LoginFlows to Quotient namespace.
