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. (cherry picked from commit a894703188a7755bb9acb897d6c31ae1af6efce0)
2023-07-13DRTVWR-558: Add apply_n(function, std::vector) for variadics.Nat Goodspeed
apply_n(function, LLSD array) has been useful, so for completeness, add the corresponding function for std::vector. Add a reference to apply_n() in comments for both apply() functions. (cherry picked from commit dfb63a92e0e9a419931caf5112e1f590924e0867)
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: Pull in LLEventDispatcher / LLDispatchListener fixes.Nat Goodspeed
For LLEventDispatcher::add(), use simpler std::enable_if construct that avoids the need to restate the whole conditional. Derive LLDispatchListener from LLEventStream, instead of containing an instance. This sets up for LazyEventAPI. Don't allow tweaking an LLDispatchListener (or subclass LLEventAPI) name. (cherry-picked from af4fbc1f8a9 on the lazy-eventpump branch) (cherry picked from commit 419e7a4230ae662b035ae771af8e7d8bceb2c8b1)
2023-07-13DRTVWR-558: Generalize LLEventDispatcher::add() constraints.Nat Goodspeed
Instead of checking whether an add() parameter is exactly LLSD or LLSDMap, check whether it's convertible to LLSD -- which handles those cases and more. (cherry picked from commit fa168c11f64771dadc5df86d14ca2f07eba3b8ba) (cherry picked from commit 6b5bfc1cf674fc568d86d7ed623fd7bb3ee2f646)
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. (cherry picked from commit de0539fcbe815ceec2041ecc9981e3adf59f2806) (cherry picked from commit 4b60941952e97691f11806062f4bc66dd5ac8dae)
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.

2023-07-08SL-18837: Force llprocess_test and llleap_test to use just 'python'.Nat Goodspeed
On GitHub Windows runners, trying to make build.yaml set PYTHON=python in the environment doesn't work: integration tests still fail with "Access is denied" because they're still trying to execute the interpreter's full pathname. Instead, make llprocess_test and llleap_test detect the case of GitHub Windows and override the environment variable PYTHON with a baked-in string constant "python".
2023-07-08SL-18837: Set APR_LOG once for the whole jobNat Goodspeed
instead of a new value for each LLProcess::create() invocation. Since the internal apr_log() function only looks at APR_LOG once per process, the first test (which succeeded, hence no log file dump) left the log file open with that same original pathname. Resetting the APR_LOG environment variable for subsequent runs only made the new code in llprocess_test look for files that were never created.

2023-06-06SL-18837: Ditch Boost.Phoenix implicit lambda syntax.Nat Goodspeed
It's cool to be able to write 'arg1 << "stuff" << var ...;' for a lambda accepting a std::ostream reference, but cascading compile errors mean it's no longer worth trying to make that work -- given actual C++ lambdas. Also clean up a lingering BOOST_FOREACH() and a boost::bind() while at it.
