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.

2022-12-02SL-18330: Fix new C++ <-> Python LLSD compatibility tests.Nat Goodspeed
When sending multiple LEAP packets in the same file (for testing convenience), use a length prefix instead of delimiting with '\n'. Now that we allow a serialization format that includes an LLSD format header (e.g. "<?llsd/binary?>"), '\n' is part of the packet content. But in fact, testing binary LLSD means we can't pick any delimiter guaranteed not to appear in the packet content. Using a length prefix also lets us pass a specific max_bytes to the subject C++ LLSD parser. Make llleap_test.cpp use new freestanding Python llsd package when available. Update Python-side LEAP protocol code to work directly with encoded bytes stream, avoiding bytes<->str encoding and decoding, which breaks binary LLSD. Make LLSDSerialize::deserialize() recognize LLSD format header case- insensitively. Python emits and checks for "llsd/binary", while LLSDSerialize emits and checks for "LLSD/Binary". Once any of the headers is recognized, pass corrected max_bytes to the specific parser. Make deserialize() more careful about the no-header case: preserve '\n' in content. Introduce debugging code (disabled) because it's a little tricky to recreate. Revert LLLeap child process stdout parser from LLSDSerialize::deserialize() to the specific LLSDNotationParser(), as at present: the generic parser fails one of LLLeap's integration tests for reasons that remain mysterious.
2022-11-29SL-18330: WIP: Send LLLeap to child as binary LLSD; generic parser.Nat Goodspeed
Since parsing binary LLSD is faster than parsing notation LLSD, send data from the viewer to the LEAP plugin child process's stdin in binary instead of notation. Similarly, instead of parsing the child process's stdout using specifically a notation parser, use the generic LLSDSerialize::deserialize() LLSD parser. Add more LLSDSerialize Python compatibility tests.
2022-11-12DRTVWR-575: Address review comments on Xcode 14.1 type tweaks.Nat Goodspeed
Introduce LLSD template constructors and assignment operators to disambiguate construction or assignment from any integer type to Integer, likewise any floating point type to Real. Use new narrow() function to validate conversions. For LLSD method parameters converted from LLSD::Integer to size_t, where the method previously checked for a negative argument, make it now check for size_t converted from negative: in other words, more than S32_MAX. The risk of having a parameter forced from negative to unsigned exceeds the risk of a valid length or index over that max. In lltracerecording.cpp's PeriodicRecording, now that mCurPeriod and mNumRecordedPeriods are size_t instead of S32, defend against subtracting 1 from 0. Use narrow() to validate newly-introduced narrowing conversions. Make llclamp() return the type of the raw input value, even if the types of the boundary values differ. std::ostream::tellp() no longer returns a value we can directly report as a number. Cast to U64.
2021-12-10SL-15742: Convert build scripts to Python 3Bennett Goble
This changeset makes it possible to build the Second Life viewer using Python 3. It is designed to be used with an equivalent Autobuild branch so that a developer can compile without needing Python 2 on their machine. Breaking change: Python 2 support ending Rather than supporting two versions of Python, including one that was discontinued at the beginning of the year, this branch focuses on pouring future effort into Python 3 only. As a result, scripts do not need to be backwards compatible. This means that build environments, be they on personal computers and on build agents, need to have a compatible interpreter. Notes - SLVersionChecker will still use Python 2 on macOS - Fixed the message template url used by template_verifier.py
2021-05-11SL-10297: Move LL_ERRS crash location into the LL_ERRS macro itself.Nat Goodspeed
Introduce Oz's LLERROR_CRASH macro analogous to the old LLError::crashAndLoop() function. Change LL_ENDL macro so that, after calling flush(), if the CallSite is for LEVEL_ERROR, we invoke LLERROR_CRASH right there. Change the meaning of LLError::FatalFunction. It used to be responsible for the actual crash (hence crashAndLoop()). Now, instead, its role is to disrupt control flow in some other way if you DON'T want to crash: throw an exception, or call exit() or some such. Any FatalFunction that returns normally will fall into the new crash in LL_ENDL. Accordingly, the new default FatalFunction is a no-op lambda. This eliminates the need to test for empty (not set) FatalFunction in Log::flush(). Remove LLError::crashAndLoop() because the official LL_ERRS crash is now in LL_ENDL. One of the two common use cases for setFatalFunction() used to be to intercept control in the last moments before crashing -- not to crash or to avoid crashing, but to capture the LL_ERRS message in some way. Especially when that's temporary, though (e.g. LLLeap), saving and restoring the previous FatalFunction only works when the lifespans of the relevant objects are strictly LIFO. Either way, that's a misuse of FatalFunction. Fortunately the Recorder mechanism exactly addresses that case. Introduce a GenericRecorder template subclass, with LLError::addGenericRecorder(callable) that accepts a callable with suitable (level, message) signature, instantiates a GenericRecorder, adds it to the logging machinery and returns the RecorderPtr for possible later use with removeRecorder(). Change llappviewer.cpp's errorCallback() to an addGenericRecorder() callable. Its role was simply to update gDebugInfo["FatalMessage"] with the LL_ERRS message, then call writeDebugInfo(), before calling crashAndLoop() to finish crashing. Remove the crashAndLoop() call, retaining the gDebugInfo logic. Pass errorCallback() to LLError::addGenericRecorder() instead of setFatalFunction(). Oddly, errorCallback()'s crashAndLoop() call was conditional on a compile-time SHADER_CRASH_NONFATAL symbol. The new mechanism provides no way to support SHADER_CRASH_NONFATAL -- it is a Bad Idea to return normally from any LL_ERRS invocation! Rename LLLeapImpl::fatalFunction() to onError(). Instead of passing it to LLError::setFatalFunction(), pass it to addGenericRecorder(). Capture the returned RecorderPtr in mRecorder, replacing mPrevFatalFunction. Then ~LLLeapImpl() calls removeRecorder(mRecorder) instead of restoring mPrevFatalFunction (which, as noted above, was order-sensitive). Of course, every enabled Recorder is called with every log message. onError() and errorCallback() must specifically test for calls with LEVEL_ERROR. LLSingletonBase::logerrs() used to call LLError::getFatalFunction(), check the return and call it if non-empty, else call LLError::crashAndLoop(). Replace all that with LLERROR_CRASH. Remove from llappviewer.cpp the watchdog_llerrs_callback() and watchdog_killer_callback() functions. watchdog_killer_callback(), passed to Watchdog::init(), used to setFatalFunction(watchdog_llerrs_callback) and then invoke LL_ERRS() -- which seems a bit roundabout. watchdog_llerrs_callback(), in turn, replicated much of the logic in the primary errorCallback() function before replicating the crash from llwatchdog.cpp's default_killer_callback(). Instead, pass LLWatchdog::init() a lambda that invokes the LL_ERRS() message formerly found in watchdog_killer_callback(). It no longer needs to override FatalFunction with watchdog_llerrs_callback() because errorCallback() will still be called as a Recorder, obviating watchdog_llerrs_callback()'s first half; and LL_ENDL will handle the crash, obviating the second half. Remove from llappviewer.cpp the static fast_exit() function, which was simply an alias for _exit() acceptable to boost::bind(). Use a lambda directly calling _exit() instead of using boost::bind() at all. In the CaptureLog class in llcommon/tests/wrapllerrs.h, instead of statically referencing the wouldHaveCrashed() function from test.cpp, simply save and restore the current FatalFunction across the LLError::saveAndResetSettings() call. llerror_test.cpp calls setFatalFunction(fatalCall), where fatalCall() was a function that simply set a fatalWasCalled bool rather than actually crashing in any way. Of course, that implementation would now lead to crashing the test program. Make fatalCall() throw a new FatalWasCalled exception. Introduce a CATCH(LL_ERRS("tag"), "message") macro that expands to: LL_ERRS("tag") << "message" << LL_ENDL; within a try/catch block that catches FatalWasCalled and sets the same bool. Change all existing LL_ERRS() in llerror_test.cpp to corresponding CATCH() calls. In fact there's also an LL_DEBUGS(bad tag) invocation that exercises an LL_ERRS internal to llerror.cpp; wrap that too.
2018-10-03DRTVWR-474: Do NOT autokill updater process on viewer termination.Nat Goodspeed
The updater is required to survive beyond termination of the viewer that launched it so it can launch the next installer, or a replacement viewer. Having the old viewer forcibly terminate it on shutdown would be counter- productive. Introduce a third LLLeap::create() overload taking LLProcess::Params, which gives access to autokill, cwd and other options previously unsupported by LLLeap. Reimplement the existing create() overloads in terms of this new one, since LLLeapImpl::LLLeapImpl() is already based on LLProcess::Params anyway. Use LLProcess::Params in LLAppViewer::init() to specify the updater process, setting autokill=false. Refactoring LLLeapImpl() apparently involved engaging an LLInitParam::Block feature never before used: had to drag operator() into Multiple from its base class TypedParam (as has been done in other TypedParam subclasses).
2016-08-17MAINT-5011: Use LLTHROW() instead of plain BOOST_THROW_EXCEPTION().Nat Goodspeed
A level of preprocessor indirection lets us later change the implementation if desired.
2016-07-19MAINT-5011: Introduce LLException base class for viewer exceptions.Nat Goodspeed
This also introduces LLContinueError for exceptions which should interrupt some part of viewer processing (e.g. the current coroutine) but should attempt to let the viewer session proceed. Derive all existing viewer exception classes from LLException rather than from std::runtime_error or std::logic_error. Use BOOST_THROW_EXCEPTION() rather than plain 'throw' to enrich the thrown exception with source file, line number and containing function.

2012-03-16Introduce LLLeapListener, associating one with each LLLeap object.Nat Goodspeed
Every LEAP plugin gets its own LLLeapListener, managing its own collection of listeners to various LLEventPumps. LLLeapListener's command LLEventPump now has a UUID for a name, both for uniqueness and to make it tough for a plugin to mess with any other.
2012-03-15Make LLLeap intercept LL_ERRS termination and notify LEAP plugin.Nat Goodspeed
Have to pump "mainloop" a few times to flush the buffer to the pipe, a potentially risky strategy: we have to trust that whatever condition led to the LL_ERRS fatal error didn't break anything that listens on "mainloop". But the worst that could happen is that the plugin won't be notified -- just as if we didn't try in the first place. In other words, no harm in trying.
2012-03-05Introduce (disabled) LLLeap debugging code to validate stdin writes.Nat Goodspeed
While debugging mysterious problem on Windows, one potential failure mode to rule out was the possibility that streaming std::ostringstream << LLSDNotationStreamer(large_LLSD) might itself cause trouble -- even before attempting to write to the LLProcess::WritePipe. The debugging code validated that the correct length is being reported, and that deserializing the resulting buffer produces equivalent LLSD. This code verified correct operation, and so has been disabled, as it's expensive at runtime.
2012-03-03Add a couple LLLeap DEBUG messages for incoming-events control flow.Nat Goodspeed
2012-03-02Use LLProcess::ReadPipe::read() in LLLeap.Nat Goodspeed
The code was using LLProcess::ReadPipe::get_istream().read(), but that's much uglier, as it requires constructing a char* buffer etc. etc.
2012-03-01Add LLLeap class, initial implementation, initial unit tests.Nat Goodspeed
Instantiating LLLeap with a command to execute a particular child process sets up machinery to speak LLSD Event API Plugin protocol with that child process. LLLeap is an LLInstanceTracker subclass, so the code that instantiates need not hold the pointer. LLLeap monitors child-process termination and deletes itself when done.
