fix(generator): defer generated event subscriptions instead of acquiring a replica (#134)
* fix(generator): defer generated event subscriptions instead of acquiring a replica
Both C++ generators emitted, at all three subscription sites (the generic
on(QString, RawEventCallback), its EventCallback overload, and every typed
on<Event>):
LogosObject* origin = ensureReplica(); // blocking requestObject
if (!origin) return false; // PERMANENT -- never retried
m_client->onEvent(origin, eventName, callback);
That asks "is the module reachable right now" at the one moment the answer is
no. Every C++ consumer subscribes from init(), onContextReady() or a backend
constructor, all of which run while the dependency's host has been spawned but
has not called listen() yet. The guard inside requestObject was dead code for
years -- isConnected() returned a latch that was always true -- so the call fell
through to a blocking wait that usually succeeded, slowly. Making isConnected()
truthful turns the same code into an instant, permanent, silent failure: the
wrapper compiles, returns a bool, and never delivers.
All three sites now route through the deferred channel:
return m_client->onEventWhenAvailable(m_moduleName, eventName, callback) != 0;
and ensureReplica() / m_eventReplica are deleted from both generators. Keeping a
per-wrapper replica would reintroduce both halves at once -- a blocking acquire
on the subscriber's thread, and a permanent failure when the module had simply
not started yet.
The return becomes ACCEPTED rather than live, false only for errors no retry can
fix. That is stated in the emitted comment so it reaches every generated file
rather than only this message.
VERIFIED AT THREE LEVELS, because the first two prove less than they look:
emits -- 265/265 cpp-sdk tests. The goldens now pin the emitted CALL SITE and
EXPECT_FALSE the removed symbols; they are string comparisons and
would pass on code that does not compile, which is exactly how this
defect survived.
compiles-- both generators' output compiled against the local protocol branch
(EXIT=0), including a 15-event contract with a 3-parameter event.
defers -- real A/B on a live qt_remote transport with real generated code:
7/7 green on the migrated generator, 3/3 red in 0-8 ms on the
pristine one, with published-first controls green in both.

* chore(deps): bump logos-protocol to 0183e8c for onEventWhenAvailable
The generator change in this PR emits `m_client->onEventWhenAvailable(...)` at
all three subscription sites. This repo pinned logos-protocol 0f26ffd, which has
zero occurrences of that symbol -- compiling the emitted wrapper against it gave
EXIT=1 and 16 errors, every one "no member named 'onEventWhenAvailable' in
'LogosAPIClient'". That is why this PR was opened as a draft and why the bump has
to ride in the SAME commit range as the emission change: split them and cpp-sdk
master is red for every Qt-api-style consumer.
0183e8c is logos-protocol master with #47, #53 and #55 in. It is deliberately not
the first commit that introduces onEventWhenAvailable: #47's tip also carries the
use-after-free fix for tryAcquireNow (09f684f), without which a consumer that
subscribes more than once to a not-yet-reachable module frees a QtRO facade that
is still registered in a shared replica implementation's connect list. Generated
Qt consumers subscribe exactly that way -- one on<Event> per declared event, from
init() -- so pinning below that commit would make this change crash rather than
merely fail to compile.

feat(generator): async callers can see the error, sync callers can set a deadline (#132)
The two consumer surfaces had complementary holes:
sync : T foo(params…, logos::CallError* err = nullptr) error yes, timeout NO
async: void fooAsync(params…, cb, Timeout = Timeout()) timeout yes, error NO
so an async caller could not tell a failed remote call from a provider that
legitimately returned 0 / "" / false — the exact ambiguity the sync path's
CallError* was added to resolve — and a sync caller could not say how long it
was willing to wait, even though the transport overload the generator already
calls takes both.
Both fixes are additive:
T foo(params…, logos::CallError* err = nullptr, Timeout timeout = Timeout());
void fooAsync(params…, std::function<void(T)> cb, Timeout timeout = Timeout()); // unchanged
void fooAsyncResult(params…, std::function<void(logos::AsyncResult<T>)> cb,
Timeout timeout = Timeout()); // new
logos::AsyncResult<T> (new, Qt-free, cpp/logos_async_result.h) is {value, error}
plus ok(); AsyncResult<void> carries only the error so every fooAsyncResult has
the same callback shape. The name is distinct rather than an overload because
std::function<void(AsyncResult<T>)> next to std::function<void(T)> is ambiguous
for a generic lambda.
Applied to both emitters that produce this surface — legacy/generator_lib.cpp
(the module-builder path) and experimental/lidl_gen_client.cpp (`--lidl
--module-only`, from a published contract) — since a consumer can reach either
for the same contract.
The Qt-free (ApiStyle::Lp) surface gets the sync timeout (spelled `int
timeout_ms`; `Timeout` lives behind a Qt header) but NOT fooAsyncResult:
logos-protocol's lp_invoke_async hard-codes `cb(1, …)`, so an AsyncResult there
would report ok() on a failed call. Measured, not assumed. See the note in
makeHeaderLp.

Make the base SDK Qt-free: Qt developer layer moves to logos-qt-sdk (#83)
* Extract the protocol layer into logos-protocol; consume it as a flake input The transport/token/IPC layer (transports incl. QRO + plain TCP/TLS, consumer core LogosAPIClient/LogosAPIConsumer with the capability auto-requestModule flow, ModuleProxy, token manager, QVariant<->JSON conversion, the abstract LogosProviderObject interface) now lives in the logos-protocol repo behind the versioned lp_* C ABI. This SDK keeps the typed C++ developer layer (LogosAPI, provider base classes + Qt provider glue, module context, code generator) and still compiles the protocol sources INTO liblogos_sdk.a from the flake input, so the installed artifact (archive symbols, include/ + include/cpp layouts, cmake config) stays byte-compatible: existing consumers need no changes. Public headers are unchanged; logos_provider_object.h keeps its name and now re-exports the abstract interface from logos_provider_interface.h. Transport/protocol component tests moved to logos-protocol with the code; the remaining sdk/generator/experimental suites are unchanged (432/432 green against the local protocol checkout). * lock: add logos-protocol input * Make the base SDK Qt-free: move the Qt developer layer to logos-qt-sdk LogosAPI, LogosAPIProvider, LogosProviderBase/LOGOS_PROVIDER macros, the QObject provider glue (QtProviderObject) and the legacy PluginInterface (core/interface.h) move to the new logos-qt-sdk repo. The protocol sources are no longer compiled into a monolithic archive — consumers link logos-qt-sdk (which layers on logos-protocol) instead. What remains here is header-only std C++: logos_module_context.h, logos_result.h (StdLogosResult), logos_json.h — exported as the CMake INTERFACE target logos-cpp-sdk::logos_headers — plus the code generator (a build-time tool; its introspection mode now includes logos_provider_interface.h from logos-protocol, where LogosProviderPlugin moved). Mechanically verified Qt-free: the logos-cpp-lib / logos-cpp-include closures contain only nlohmann_json. Tests: 245/245 (module-context std suite + generator + experimental). * fix: accept the installed source-export layout in the protocol-root check The fail-fast only tested <root>/cpp/logos_protocol.h, but the LP_SRC selection right below (and the error message itself) support the installed export layout <root>/include/cpp as well. Pointing LOGOS_PROTOCOL_ROOT at an installed export tripped the FATAL_ERROR before that fallback could apply. Caught by Copilot review on #82. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * lock: pin logos-protocol to the qt-free-split branch head The Qt-free SDK (and the cdylib backend stacked on it) reference LogosProviderPlugin from protocol's logos_provider_interface.h, which lands on feat/qt-free-split — the P1-branch pin no longer compiles standalone. Temporary — drop when the chain PRs merge. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * doctest: pin the logoscore runtime via its {release} placeholder The spec built logoscore-cli at bare master with only the cpp-sdk inputs overridden — master's stack cannot compile against the qt-free SDK, so the suite failed on the chain branches. With the placeholder, CI's --release-for pins expand it to the workspace's logoscore commit (and local runs without a pin still fall back to master, unchanged). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * doctest: override the nested module builders to {release} too capability_module (via logoscore's lock) and the cloned accounts module resolve module-builder from their own locks — pre-split revs whose LogosModule.cmake still detects the SDK by logos_api.h, which the qt-free SDK no longer ships ('logos-cpp-sdk not found'). Overriding the builder itself to the workspace-pinned chain rev (keeping the nested cpp-sdk override) builds both modules with the split-aware builder. Verified end-to-end locally with the exact doctest command. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * doctest: apply the {release} + nested-builder overrides to all three specs The runtime spec got the treatment in 210eea1; the composition and worker-thread specs have the same logoscore/module build commands and failed identically (pre-split builders from the modules' own locks). All executed run: blocks now pin logoscore-cli{release} and override the nested module builders to logos-module-builder{release}; the displayed code_block: variants stay in their generic master form. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * codegen: typed wrappers throw on call failure; dispatch catches escapes Generated sync client wrappers call the new err-out invokeRemoteMethod overload and throw logos::LogosCallError when the call fails (e.g. the bound module is missing) — previously the empty QVariant silently degraded to the return type's default and a caller could not tell failure from a legitimate 0 / "". Both generators (legacy + LIDL), both API styles. Async paths unchanged. Generated provider dispatch (universal qt glue + LOGOS_PROVIDER) wraps the method body in a catch-all that logs and returns an invalid QVariant — an escaped exception becomes an ordinary METHOD_FAILED instead of unwinding through Qt event dispatch and killing the module process. * codegen: CallError out-param instead of throwing wrappers Per review, the generated sync wrappers expose the error channel as an optional trailing parameter — add(a, b, &err) — rather than throwing: explicit, stateless, works on temporaries, and existing call sites compile unchanged (they keep default-on-failure, now with a qWarning so failures are visible in the module log). The dispatch catch-all from the previous commit stays: it contains author exceptions, it doesn't introduce any. * glue: fire onContextReady AFTER modules()/event wiring The generated onInit set the context (which fires the impl's onContextReady hook) before constructing the LogosModules aggregate and wiring typed event emission — so an impl doing its documented one-time setup there (typed dependency calls, event subscriptions) dereferenced a null aggregate and crashed the module process (signal 11). Found by the first module to subscribe to a dependency's typed event from onContextReady. Context now goes last. * ci: run workflows on stacked PRs + workflow_dispatch Both workflows filtered pull_request to master-based PRs, so stacked PRs (feat/qt-free-sdk -> feat/extract-logos-protocol, feat/cdylib-authoring -> feat/qt-free-sdk) ran NO checks at all. Drop the base-branch filter for pull_request and add workflow_dispatch for manual runs. Same fix as logos-module-builder 232b8a2. * lock: protocol at the typed-requestModule port (3de5398) * ci: chain pins for the doc-tests (drop at merge) In repo CI only cpp-sdk's {release} is the commit under test — logoscore-cli and module-builder expanded to master, which doesn't link against the chain SDK the specs override in ('Build the CLI with the SDK override' failed on every run since the stacked-PR triggers were enabled). Pin both to the extraction-chain heads; the workspace pipeline is unaffected (it pins every repo itself). * generator: distribute the LIDL frontend for external generators First step of moving ALL Qt glue emission out of this repo into logos-qt-sdk's logos-qt-generator (cpp-sdk's generator keeps only the Qt-free outputs: std typed wrappers, logos_sdk umbrella, cdylib impl-exports, LIDL derivation). - Shared emit helpers (lidlToPascalCase, lidlTypeToQt, lidlTypeToStd, lidlIsStdConvertible) move to a new lidl_emit_common.{h,cpp} unit, used by both generators. - The frontend set (AST, lexer, parser, serializer, validator, impl-header parser, emit-common) is installed under share/lidl-frontend/ — the qt generator compiles these sources in directly, so the two tools share one frontend without a binary ABI. * lock: protocol#3 merged — pin advances to protocol master --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |
