* Extract the Logos protocol layer from logos-cpp-sdk
Transports (plain TCP/TLS, qt_local, qt_remote/QRO, mock), token manager,
consumer core (LogosAPIClient/LogosAPIConsumer incl. the capability
auto-requestModule flow), ModuleProxy, the abstract LogosProviderObject
interface, and the canonical QVariant<->JSON conversion — now behind the
language-neutral lp_* C ABI (logos_protocol.h) carrying the protocol
semver (LOGOS_PROTOCOL_VERSION_*, lp_protocol_version()).
Bytes crossing the ABI use the lossless {"_bytes": base64url} tagging
(NUL-safe), matching the plain wire encoding.
Provider lp_* surface is compiled groundwork; serving lands with module
authoring.
* Move LogosProviderPlugin into logos_provider_interface.h
Plugin-loading tools (logos-cpp-generator's introspection mode, lm, the
hosts) need only qobject_cast<LogosProviderPlugin*>() + the abstract
LogosProviderObject — both framework-internal. Hosting the detection
interface here keeps those tools off the developer-facing logos-qt-sdk
layer. Same iid (org.logos.LogosProviderPlugin); header-only, ABI-neutral.
* Define the common module-impl C ABI (logos_module_impl.h)
ONE cdylib contract for module implementations in every language:
dispatch / get_methods / set_context / set_emit_callback / accept_token
/ get_protocol_version / string_free. The C++ and Rust SDKs emit these
exports around their respective impls; the uniform generated Qt glue
(and later a no-Qt host) talks to the cdylib only through this ABI.
JSON data model and tagged bytes form match the lp_* consumer ABI; the
protocol-version handshake complements the build-time metadata stamp.
* json convert: integers stay integers across the C ABI
QJsonValue::fromVariant degrades every numeric to double, so Int/UInt/
LongLong/ULongLong QVariants serialized as 5.0 — and a strict consumer on
the other side of the C ABI (a generated dispatch reading an int param)
rejects or zeroes them. Surfaced by the first cdylib-authored module
whose inbound args cross qvariantToNlohmann; the dlopen smoke harness
fed hand-written int JSON and never exercised this edge.
* call-error channel: surface {code,message,origin} for unacquirable targets
invokeRemoteMethod could not distinguish a failed call from a void/null
result — lp_invoke returned LP_OK with a null JSON result even when the
target module was never reached, and generated typed wrappers silently
defaulted (0 / empty string). Additive err-out overloads on
LogosAPIConsumer/LogosAPIClient fill a std-only logos::CallError
(logos_call_error.h, new LogosCallError exception for the generated
wrappers to throw); lp_invoke now honors its documented contract for
this class of failure: LP_ERR_UNAVAILABLE + canonical error JSON.
First detectable code: object_unavailable (requestObject failure) —
the struct is the extension point for transport-level statuses.
* call-error: drop the exception type — the error channel is the out-param
Per review, generated wrappers expose CallError as an optional trailing
out-parameter instead of throwing; the struct is the whole contract.
* ci: build + run the protocol test suite
On every pull request (unfiltered — stacked PRs included), master pushes,
and manual dispatch. The repo shipped without CI; its 111-test suite only
ran locally and through the workspace gate.
* consumer: typed requestModule for the capability flow
Port of logos-cpp-sdk master f5a127dd ('use updated capability module',
cpp-sdk#85, Iuri Matias) — the touched files (logos_api_client.cpp,
logos_api_consumer.{h,cpp}) moved into this repo in the P1 extraction.
The capability auto-requestModule path now calls a typed std::string
helper on the consumer (which acquires the capability object directly)
instead of a stringly invokeRemoteMethod round-trip. 111/111 tests.
* ci: DeterminateSystems nix installer (macOS runners)
cachix/install-nix-action fails on the macOS runners with
eDSRecordAlreadyExists (pre-existing nix build users); the org's
macOS-bearing workflows use the DeterminateSystems installer.
