It's too easy to incorrectly test the previous return type.

Facility macros to report Olm errors: QOLM_INTERNAL_ERROR[_X],
QOLM_FAIL_OR_LOG[_X]
|
|
Notably:
- simplified unnecessarily verbose constructs;
- formally aligned (no re-numeration was necessary)
QOlmMessage::Type with corresponding OLM_ constants;
- dropped QOlmSession::encryptMessageType() because it's very
sensitive to the order of calling with QOlmSession::encrypt()
(and encrypt() itself already calls it and returns the message
type);
- simplify the return type of pickle() calls that can only fail due to
an internal error;
- replace const QString& with QStringView or const QByteArray&
where appropriate;
- use '\0' where it was meant to be instead of '0'.

QOlmError represents a subset of OlmErrorCode, and the associated
fromString() function uses undocumented strings produced inside Olm;
meanwhile OlmErrorCode is documented in its own header file. Each QOlm*
class now has lastErrorCode() next to lastError() (that, from now,
returns a textual representation straight from Olm, not QOlmError enum).
Also: including olm/error.h in e2ee/e2ee.h required some rearrangement
of the code to make sure non-E2EE configuration still builds.

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).

Mainly the change is about eliminating the checks for an exact number
of key-value pairs inside `one_time_key_counts` - these checks started
failing with new Synapse throwing `signed_curve25519: 0` into this dict.

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.

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.

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()`

It would probably be even better to pass the homeserver address in
the environment but that's a bigger endeavour.
Also: reformatted CREATE_CONNECTION macro.

Remove qtolm git module. Update CMakeLists.txt.
Rename olm to crypto subdir to prevent disambiguation. Rename internal
files accordingly. Comment out not ported E2EE API usage.
