2023-07-28DRTVWR-587: Use [[noreturn]] attribute on callFail() methodsNat Goodspeed
that unconditionally return. This eliminates the problem of pacifying a compiler that expects a return statement vs. a compiler that detects that callFail() unconditionally throws. Thanks, Ansariel.

2023-07-27DRTVWR-587: Make LLSDParam<LLSD> simplify type when delegating.Nat Goodspeed
LLSDParam<LLSD> is the generic case, when we need to pass LLSDParam adapters to some set of function parameters whose types we don't specifically know. Its templated conversion operator notices the actual parameter type T and delegates conversion to the specific LLSDParam<T> specialization. But when T has picked up references, e.g. somewhere along the way in the LL::apply() machinery, the compiler might not choose the desired conversion because we don't have a sufficiently specific LLSDParam specialization. LLSDParam<LLSD> can address that by using std::decay_t<T> when delegating to the specific LLSDParam specialization. This removes references, const and volatile.

2023-07-13DRTVWR-558: Constrain LL::apply()'s use of std::apply().Nat Goodspeed
Once std::apply() becomes available, 'using std::apply;' isn't correct because the more general template tries to handle the apply(function, vector) case that we explicitly implement below. Have to provide apply(function, tuple) and apply(function, array) signatures that can forward to std::apply().

2023-07-13DRTVWR-558: Fix LLEventDispatcher::addMethod() for LazyEventAPI.Nat Goodspeed
addMethod() was using dynamic_cast<target class*>(this) and testing for nullptr to decide whether the class owning the passed method is, or is not, a subclass of LLEventDispatcher. The trouble is that it doesn't work for the deferred add() calls queued by LazyEventAPI: the dynamic_cast was always returning nullptr. static_cast works better, but that leaves us with the problem we were trying to solve with dynamic_cast: what if the target class really isn't a subclass? Use std::is_base_of to pick which of two addMethod() overloads to invoke, one of which calls addFail(). (cherry picked from commit a4d520aa5d023d80cfeec4f40c3464b54cbcfc5b)

2023-07-13DRTVWR-558: Nail down LLDispatchListener exception handlingNat Goodspeed
for exceptions other than those thrown by base-class LLEventDispatcher. Explain in LLDispatchListener Doxygen comments that for a request lacking a "reply" key, any exception is allowed to propagate because it's likely to reach the post() call that triggered the exception in the first place. For batch LLDispatchListener operations, catch not only LLEventDispatcher:: DispatchError exceptions but any std::exception, so we can collect them to report to the invoker. "Gotta catch 'em all!" Make LLLeap catch any std::exception thrown by processing a request from the plugin child process, log it and send a reply to the plugin. No plugin should be allowed to crash the viewer. (cherry picked from commit 94e10fd039b79f71ed8d7e10807b6e4eebd1928c)
2023-07-13DRTVWR-558: Enrich LLEventDispatcher::callFail() with current call.Nat Goodspeed
Now an LLEventAPI subclass method can call callFail(...) to report an error, and the error will be annotated with the leaf class name, the instance name and the way the method was reached. The enriched error message will be logged and either sent back to the invoker or propagated as an exception, depending on the invocation tactic. In other words, a business method can use callFail() to Do The Right Thing according to the LLEventDispatcher contract. Introduce a nested SetState RAII class to set and clear transient state. SetState's constructor accepts variadic stringize() arguments. The resulting message is passed to LLEventDispatcher::setState(), which requires a SetState reference because ONLY SetState should call setState(): state data really is intended to be transient. SetState guarantees it will be cleared every time it's set. setState() respects previously-set transient state. If a call from an inner function finds that transient state was already set by some ancestor, it ignores the call and informs the caller by returning false. This lets a given SetState instance recognize whether it is responsible for clearing the current transient state. operator<<(std::ostream&, const LLEventDispatcher&) now appends getState() to the data reported by streaming *this. Non-static LLEventDispatcher::callFail() already prepends *this to the reported error message. Transient state is managed by a fiber_specific_ptr, since different threads and even different fibers within a thread might be concurrently performing different operations on the same LLEventDispatcher. Introduce a back pointer to the parent LLEventDispatcher in DispatchEntry. Populate it with a new constructor parameter, propagated through every subclass constructor. Hoist ParamsDispatchEntry::callFail() up into its DispatchEntry base class. Make it call non-static LLEventDispatcher:: callFail(), which prepends the reported error with instance and transient state info. Use DispatchEntry::callFail() in LLSDDispatchEntry::call(), instead of redundantly calling LLEventDispatcher::callFail(). Similarly, introduce an LLEventDispatcher back pointer into LLSDArgsMapper for use by its own callFail() method. The above should (!) eliminate the need to replicate LLEventDispatcher instance info into every helper object's descriptive strings. In particular, since the previous info was stored in each object by its constructor, it couldn't report associated transient information about how the subject callable was actually reached. Traversing a back pointer to the live LLEventDispatcher instance gets us the most current state. Make the internal three-argument LLEventDispatcher::try_call() method, which implements each of the operator()() and public try_call() methods, use SetState to append "[name]" (for explicit operator()(name, event) calls) or "[key=name]" (for implicit operator()(event) calls) to streamed *this. In the new LLDispatchListener request array and request map operations, use SetState to indicate the current entry in the array or map, overriding the lower-level state set by three-argument LLEventDispatcher::try_call().

2023-07-13DRTVWR-558: Extend LLEventDispatcher::add() overloads.Nat Goodspeed
Add LL::always_return<T>(), which takes a callable and variadic arguments. It calls the callable with those arguments and, if the returned type is convertible to T, converts it and returns it. Otherwise it returns T(). always_return() is generalized from, and supersedes, LLEventDispatcher::ReturnLLSD. Add LL::function_arity<CALLABLE>, which extends boost::function_types::function_arity by reporting results for both std::function<CALLABLE> and boost::function<CALLABLE>. Use for LL::apply(function, LLSD array) as well as for LLEventDispatcher. Make LLEventDispatcher::add() overloads uniformly distinguish between a callable (whether non-static member function or otherwise) that accepts a single LLSD parameter, versus any other signature. Accepting exactly one LLSD parameter signals that the callable will accept the composite arguments LLSD blob, instead of asking LLEventDispatcher to unpack the arguments blob into individual arguments. Support add(subclass method) overloads for arbitrary-parameters methods as well as for (const LLSD&) methods. Update tests accordingly: we need no longer pass the boilerplate lambda instance getter that binds and returns 'this'. Extract to the two LLEventDispatcher::make_invoker() overloads the LL::apply() logic formerly found in ReturnLLSD. Change lleventdispatcher_test.cpp tests from boost::bind(), which accepts variadic arguments (even though it only passes a fixed set to the target callable), to fixed-signature lambdas. This is because the revamped add() overloads care about signature. Add a test for a non-static method that accepts (const LLSD&), in other words the composite arguments LLSD blob, and likewise returns LLSD.

2023-07-13DRTVWR-558: Clean up LLEventDispatcher argument and result handling.Nat Goodspeed
Add a new LLEventDispatcher constructor accepting not only the map key to extract a requested function name, but a second map key to extract the arguments -- when required. In Doxygen comments, clarify the difference between the two constructors. Move interaction with the LLEventPump subsystem to LLDispatchListener. LLEventDispatcher is intended to be directly called. On error, instead of looking for a "reply" key in the invocation LLSD, throw DispatchError. Publish DispatchError, formerly an implementation detail, and its new subclass DispatchMissing. Make both LLEventDispatcher::operator()() overloads return LLSD, leveraging the new internal ReturnLLSD logic that returns a degenerate LLSD blob for a void target callable and, for compatible types, converts the returned value to LLSD. Notably, the public try_call() overloads still return bool; any value returned by the target callable is discarded. Clarify the operator() and try_call() argument requirements for target callables registered to accept an LLSD array, in Doxygen comments and in code. In particular, the 'event' passed to (event) overloads (vs. the (name, event) overloads) must be an LLSD map, so it must contain an "args" key (or the new arguments map key specified to the constructor) containing the LLSD args array. Since the use of the new args key depends on whether the target callable is registered to accept an array or a map, pass it into DispatchEntry::call() (and all subclass overrides), along with a bool to disambiguate whether we reached that method from an LLEventDispatcher (event) invocation method or a (name, event) invocation method. Allow streaming an LLEventDispatcher instance to std::ostream, primarily to facilitate construction of proper error messages. Revert the 'name' argument of internal try_call(key, name, event) to std::string. Ditch try_call_log(), try_call_one() and reply(). Fold try_call_one() logic into three-argument try_call(). Refactor callFail() as a template method accepting both the exception to throw and arbitrary stringize() arguments from which to construct the exception message. Non-static callFail() implicitly prepends the instance and a colon to the rest of the arguments, and calls static sCallFail(). The latter constructs the exception message, logs it and throws the specified exception. This obviates try_call_log(). Make implementation detail helper class LLSDArgsMapper a private member of LLEventDispatcher so it can access sCallFail(): we now want all error handling to go through that method. Add LLSDArgsMapper::callFail() resembling LLSDEventDispatcher::callFail(), but without having to specify the exception: only LLEventDispatcher will throw anything but generic DispatchError. Give LLEventDispatcher::ParamsDispatchEntry and its subclasses ArrayParamsDispatchEntry and MapParamsDispatchEntry a new 'name' argument to identify error messages. Store it and use it implicitly in new callFail() method, very like LLSDArgsMapper::callFail(). Make LLEventDispatcher:: addArrayParamsDispatchEntry() and addMapParamsDispatchEntry() pass a 'name' that includes the LLEventDispatcher instance name as well as the name of the specific registered callable. This way we need not intercept a low-level error and annotate it with contextual data: we can just let the exception propagate. Make ParamsDispatchEntry::call() override catch LL::apply_error thrown by an invoker_function, and pass its message to callFail(), i.e. rethrow as LLEventDispatcher::DispatchError. Introduce ArrayParamsDispatchEntry::call() override for the special logic to extract an arguments array from a passed LLSD map -- but only under the circumstances described in the Doxygen comment. Add similar logic to MapParamsDispatchEntry::call(), but with both argskey itself and a value for argskey optional in the passed LLSD map. Because LLEventDispatcher now has two constructor overloads, allow subclass constructor LLDispatchListener() to accept zero or more trailing arguments. This is different than giving LLDispatchListener's constructor a default final argument, in that the subclass doesn't need to specify its default value: that's up to the base-class constructor. But it does require that the subclass constructor move to the header file. Move private LLEventDispatcher::reply() method to LLDispatchListener. Extend LLDispatchListener::process() to handle DispatchError by attempting to reply with a map containing an "error" key, per convention. (In other words, move that logic from LLEventDispatcher to LLDispatchListener.) Also, for a map LLSD result, attempt to reply with that result; for other defined LLSD types, attempt to reply with a map containing a "data" key. This is backwards compatible with previous behavior because all previous LLDispatchListener subclass methods returned void, which now produces an undefined LLSD blob, which we don't bother trying to send in reply. In lleventdispatcher_test.cpp, rework tut::lleventdispatcher_data::call_exc() yet again to catch DispatchError instead of listening for an LLEventPump reply event. Similarly, make call_logerr() catch DispatchError. Since the exception should also be logged, we ignore it and focus on the log, as before. Add tests <23> to <27>, exercising calls to new class DispatchResult methods returning string, int, LLSD map, LLSD array and void. (cherry picked from commit 2f9c915dd3d5137b5b2b1a57f0179e1f7a090f8c)

2023-07-13DRTVWR-558: Support LLStoreListener<LLSD>, add LLCaptureListener.Nat Goodspeed
LLStoreListener<LLSD> didn't work because of an ambiguity problem. Resolve that by introducing an internal storeTarget() method. Introduce LLCaptureListener<T> that's both an LLStoreListener and the variable into which to capture the expected result. Introduce LLVarHolder<T> to contain the variable, so we can guarantee the actual data member will be fully constructed by the time we want to pass it to the LLStoreListener base class.

2023-07-13DRTVWR-558: LLEventDispatcher uses LL::apply(), not boost::fusion.Nat Goodspeed
While calling a C++ function with arguments taken from a runtime-variable data structure necessarily involves a bit of hocus-pocus, the best you can say for the boost::fusion based implementation is that it worked. Sadly, template recursion limited its applicability to a handful of function arguments. Now that we have LL::apply(), use that instead. This implementation is much more straightforward. In particular, the LLSDArgsSource class, whose job was to dole out elements of an LLSD array one at a time for the template recursion, goes away entirely. Make virtual LLEventDispatcher::DispatchEntry::call() return LLSD instead of void. All LLEventDispatcher target functions so far have been void; any function that wants to respond to its invoker must do so explicitly by calling sendReply() or constructing an LLEventAPI::Response instance. Supporting non- void functions permits LLEventDispatcher to respond implicitly with the returned value. Of course this requires a wrapper for void target functions that returns LLSD::isUndefined(). Break out LLEventDispatcher::reply() from callFail(), so we can reply with success as well as failure. Make LLEventDispatcher::try_call_log() prepend the actual leaf class name and description to any error returned by three-arg try_call(). That try_call() overload reported "LLEventDispatcher(desc): " for a couple specific errors, but no others. Hoist to try_call_log() to apply uniformly. Introduce new try_call_one() method to diagnose name-not-found errors and catch internal DispatchError and LL::apply_error exceptions. try_call_one() returns a std::pair, containing either an error message or an LLSD value. Make try_call_log() and three-arg try_call() accept LLSD 'name' instead of plain std::string, allowing for the possibility of an array or map. That lets us extend three-arg try_call() to break out new cases for the function selector LLSD: isUndefined(), isArray(), isMap() and (current case) scalar String. If try_call_one() reports an error, log it and try to send reply, as now. If it returns LLSD::isUndefined(), e.g. from a void target function wrapper, do nothing. But if it returns an LLSD map, try to send that back to the invoker. And if it returns an LLSD scalar or array, wrap it in a map with key "data" to respond to the invoker. Allowing a target function to return its result rather than explicitly sending it opens the possibility of batched requests (aggregate 'name') returning batched responses. Almost every place that constructs LLEventDispatcher's internal DispatchError exception called stringize() to format the what() string. Simplify calls by making DispatchError accept variadic arguments and forward to stringize(). Add LL::invoke() to apply.h. Like LL::apply(), this is a (limited) C++14 foreshadowing of std::invoke(), with preprocessor conditionals to switch to std::invoke() when that's available. Introduce LL::invoke() to handle a callable that's actually a pointer to method. Now our C++14 apply() implementation can accept pointer to method, using invoke() to generalize the actual function call. Also anticipate std::bind_front() with LL::bind_front(). For apply(func, std::array) and our extensions apply(func, std::vector) and apply(func, LLSD), we can't pass a pointer to method as the func unless the second argument happens to be an array or vector of pointers (or references) to instances of exactly the right class -- and of course LLSD can't store such at all. It's tempting to pass std::bind(std::mem_fn(ptr_to_method), instance), but that won't work: std::bind() requires a value or placeholder for each argument to pass to the bound function. The bind() expression above would only work for a nullary method. std::bind_front() would work, but that doesn't arrive until C++20. Again, once we get there we'll defer to the std:: implementation. Instead of the generic __cplusplus, check the appropriate feature-test macro for availability of each of std::invoke(), std::apply() and std::bind_front(). Change apply() error handling from assert() to new LL::apply_error exception. LLEventDispatcher must be able to intercept apply() errors. Move validation and synthesis of the relevant error message to new apply.cpp source file. Add to llptrto.h new LL::get_ref() and LL::get_ptr() template functions to unify the cases of a calling template accepting either a pointer or a reference. Wrapping the parameter in either get_ref() or get_ptr() allows dereferencing the parameter as desired. Move LL::apply(function, LLSD) argument validation/manipulation to a non- template function in llsdutil.cpp: no need to replicate that logic in the template for every CALLABLE specialization. The trouble with passing bind_front(std::mem_fn(ptr_to_method), instance) to apply() is that since bind_front() accepts and forwards variadic additional arguments, apply() can't infer the arity of the bound ptr_to_method. Address that by introducing apply_n<arity>(function, LLSD), permitting a caller to infer the arity of ptr_to_method and explicitly pass it to apply_n(). Polish up lleventdispatcher_test.cpp accordingly. Wrong LLSD type and wrong number of arguments now produce different (somewhat more informative) error messages. Moreover, passing too many entries in an LLSD array used to work: the extra arguments used to be ignored. Now we require that the size of the array match the arity of the target function. Change the too-many-arguments tests from success testing to error testing. Replace 'foreach' aka BOOST_FOREACH macro invocations with range 'for'. Replace STRINGIZE(item0 << item1 << ...) with stringize(item0, item1, ...). (cherry picked from commit 9c049563b5480bb7e8ed87d9313822595b479c3b)

2023-07-13DRTVWR-558: LLEventAPI allows all LLEventDispatcher add() overloads.Nat Goodspeed
Previously, LLEventAPI intentionally hid all but one of the many add() overloads supported by its LLEventDispatcher base class. The reason was that certain of the add() methods take an optional fourth parameter that's an LLSD::Map describing the expected parameter structure, while others take a fourth templated parameter that's an instance getter callable. This led to ambiguity, especially when passed an LLSDMap instance that's convertible to LLSD but isn't literally LLSD. At the time, it was simpler to constrain the add() methods inherited from LLEventDispatcher. But by adding new std::enable_if constraints to certain LLEventDispatcher add() methods, we've resolved the ambiguities, so LLEventAPI subclasses can now use any add() overload (as claimed on the relevant Confluence page). LLEventDispatcher comments have always loftily claimed that an instance getter callable may return either a pointer or a reference, doesn't matter. But it does when trying to pass the getter's result to boost::fusion::push_back(): a reference must be wrapped with std::ref() while a pointer cannot be. std::ref(pointer) produces errors. Introduce LLEventDispatcher::invoker:: bindable() overloads to Do The Right Thing whether passed a pointer or a reference.

2023-07-13DRTVWR-558: Change LLEventDispatcher error action (also LLEventAPI).Nat Goodspeed
Originally the LLEventAPI mechanism was primarily used for VITA testing. In that case it was okay for the viewer to crash with LL_ERRS if the test script passed a bad request. With puppetry, hopefully new LEAP scripts will be written to engage LLEventAPIs in all sorts of interesting ways. Change error handling from LL_ERRS to LL_WARNS. Furthermore, if the incoming request contains a "reply" key, send back an error response to the requester. Update lleventdispatcher_test.cpp accordingly.

2023-07-13DRTVWR-558: Tweak LLEventDispatcher.Nat Goodspeed
Instead of std::map<std::string, boost::shared_ptr>, use std::unique_ptr as the mapped_type, using emplace() to store new entries. This more correctly captures the desired semantics: we have no intention of passing around the pointers in the map, we just want the map to delete them on destruction. Use std::function instead of boost::function. (cherry picked from commit 7ba53ef82db5683756e296225f0c8b838420a26e)

2023-07-13DRTVWR-558: Add unit test for VAPPLY().Nat Goodspeed
Add to apply_test.cpp a collect() function that incrementally accumulates an arbitrary number of arguments into a std::vector<std::string>. Construct a std::array<std::string> to pass it, using VAPPLY(). Clarify in header comments that LL::apply() can't call a variadic function with arguments of dynamic size: std::vector or LLSD. The compiler can deduce how many arguments to pass to a function with a fixed argument list; it can deduce how many arguments to pass to a variadic function with a fixed number of arguments. But it can't compile a call to a variadic function with an arguments data structure whose size can vary at runtime. (cherry picked from commit ceed33396266b123896f7cfb9b90abdf240e1eec)
2023-07-13DRTVWR-558: Extend LL::apply() to LLSD array arguments.Nat Goodspeed
Make apply(function, std::array) and apply(function, std::vector) available even when we borrow the C++17 implementation of apply(function, std::tuple). Add apply(function, LLSD) with interpretations: * isUndefined() is treated as an empty array, for calling a nullary function * scalar LLSD is treated as a single-entry array, for calling a unary function * isArray() converts function parameters using LLSDParam * isMap() is an error. Add unit tests for all flavors of LL::apply(). (cherry picked from commit 3006c24251c6259d00df9e0f4f66b8a617e6026d)
2023-07-13DRTVWR-558: Fix builds on macOS 12.5 Monterey.Nat Goodspeed
Always search for python3[.exe] instead of plain 'python'. macOS Monterey no longer bundles Python 2 at all. Explicitly make PYTHON_EXECUTABLE a cached value so if the user edits it in CMakeCache.txt, it won't be overwritten by indra/cmake/Python.cmake. Do NOT set DYLD_LIBRARY_PATH for test executables! That has Bad Effects, as discussed in https://stackoverflow.com/q/73418423/5533635. Instead, create symlinks from build-mumble/sharedlibs/Resources -> Release/Resources and from build-mumble/test/Resources -> ../sharedlibs/Release/Resources. For test executables in sharedlibs/RelWithDebInfo and test/RelWithDebInfo, this supports our dylibs' baked-in load path @executable_path/../Resources. That load path assumes running in a standard app bundle (which the viewer in fact does), but we've been avoiding creating an app bundle for every test program. These symlinks allow us to continue doing that while avoiding DYLD_LIBRARY_PATH. Add indra/llcommon/apply.h. The LL::apply() function and its wrapper macro VAPPLY were very useful in diagnosing the problem. Tweak llleap_test.cpp. This source was modified extensively for diagnostic purposes; these are the small improvements that remain.
