2022-02-27Merge #536: Use QOlmMessage::Type in more placesAlexey Rusakov
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
2022-02-26Handle 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.

2022-02-24Fix all testsTobias Fella
2022-02-16More cleanup, especially in EncryptedFileAlexey Rusakov
For EncryptedFile: - JSON converter bodies moved away to .cpp; - instead of C-style casts, reinterpret_cast is used to convert from (const) char* to (const) unsigned char*; - the size for the target plain text takes into account the case where the cipher block size can be larger than 1 (after reading https://www.openssl.org/docs/man1.1.1/man3/EVP_DecryptUpdate.html). - file decryption is wrapped in #ifdef Quotient_E2EE_ENABLED, to avoid OpenSSL linking errors when compiling without E2EE.
2022-02-16isSupportedAlgorithm()Alexey Rusakov
That's a better primitive than just exposing SupportedAlgorithms list.
2022-02-16Connection: guard device loading per-objectAlexey Rusakov
Using a static variable is incorrect as it doesn't load the device list for any subsequent created Connection object.
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).
2022-02-13Merge branch 'dev'Alexey Rusakov
The result is FTBFS as yet; next commits will fix that, along with a few other things.

2022-01-18AccountRegistry: derive from QVector and clean upAlexey Rusakov
Notably, Quotient::AccountRegistry::instance() is now deprecated in favour of Quotient::Accounts inline variable.
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.
2021-12-27Connection: Simplify room/user factory codeAlexey Rusakov
There's no need to return lambdas where pointers to specialised function templates would work just fine.

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.
