From 623ac79120a417ec445ce5c106a907fe46734309 Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Thu, 7 Oct 2021 15:32:51 -0400 Subject: SL-16024: Add LL::WorkQueue for passing work items between threads. A typical WorkQueue has a string name, which can be used to find it to post work to it. "Work" is a nullary callable. WorkQueue is a multi-producer, multi-consumer thread-safe queue: multiple threads can service the WorkQueue, multiple threads can post work to it. Work can be scheduled in the future by submitting with a timestamp. In addition, a given work item can be scheduled to run on a recurring basis. A requesting thread servicing a WorkQueue of its own, such as the viewer's main thread, can submit work to another WorkQueue along with a callback to be passed the result (of arbitrary type) of the first work item. The callback is posted to the originating WorkQueue, permitting safe data exchange between participating threads. Methods are provided for different kinds of servicing threads. runUntilClose() is useful for a simple worker thread. runFor(duration) devotes no more than a specified time slice to that WorkQueue, e.g. for use by the main thread. --- indra/llcommon/workqueue.cpp | 114 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 114 insertions(+) create mode 100644 indra/llcommon/workqueue.cpp (limited to 'indra/llcommon/workqueue.cpp') diff --git a/indra/llcommon/workqueue.cpp b/indra/llcommon/workqueue.cpp new file mode 100644 index 0000000000..15e292fb43 --- /dev/null +++ b/indra/llcommon/workqueue.cpp @@ -0,0 +1,114 @@ +/** + * @file workqueue.cpp + * @author Nat Goodspeed + * @date 2021-10-06 + * @brief Implementation for WorkQueue. + * + * $LicenseInfo:firstyear=2021&license=viewerlgpl$ + * Copyright (c) 2021, Linden Research, Inc. + * $/LicenseInfo$ + */ + +// Precompiled header +#include "linden_common.h" +// associated header +#include "workqueue.h" +// STL headers +// std headers +// external library headers +// other Linden headers +#include "llerror.h" +#include "llexception.h" +#include "stringize.h" + +LL::WorkQueue::WorkQueue(const std::string& name): + super(makeName(name)) +{ + // TODO: register for "LLApp" events so we can implicitly close() on + // viewer shutdown. +} + +void LL::WorkQueue::close() +{ + mQueue.close(); +} + +void LL::WorkQueue::runUntilClose() +{ + try + { + for (;;) + { + callWork(mQueue.pop()); + } + } + catch (const Queue::Closed&) + { + } +} + +bool LL::WorkQueue::runPending() +{ + for (Work work; mQueue.tryPop(work); ) + { + callWork(work); + } + return ! mQueue.done(); +} + +bool LL::WorkQueue::runOne() +{ + Work work; + if (mQueue.tryPop(work)) + { + callWork(work); + } + return ! mQueue.done(); +} + +bool LL::WorkQueue::runUntil(const TimePoint& until) +{ + // Should we subtract some slop to allow for typical Work execution time? + // How much slop? + Work work; + while (TimePoint::clock::now() < until && mQueue.tryPopUntil(until, work)) + { + callWork(work); + } + return ! mQueue.done(); +} + +std::string LL::WorkQueue::makeName(const std::string& name) +{ + if (! name.empty()) + return name; + + static thread_local U32 discriminator = 0; + return STRINGIZE("WorkQueue" << discriminator++); +} + +void LL::WorkQueue::callWork(const Queue::DataTuple& work) +{ + // ThreadSafeSchedule::pop() always delivers a tuple, even when + // there's only one data field per item, as for us. + callWork(std::get<0>(work)); +} + +void LL::WorkQueue::callWork(const Work& work) +{ + try + { + work(); + } + catch (...) + { + // No matter what goes wrong with any individual work item, the worker + // thread must go on!

ThreadPool bundles a WorkQueue with the specified number of worker threads to service it. Each ThreadPool has a name that can be used to locate its WorkQueue. Each worker thread calls WorkQueue::runUntilClose(). ThreadPool listens on the "LLApp" LLEventPump for shutdown notification. On receiving that, it closes its WorkQueue and then join()s each of its worker threads for orderly shutdown. Add a settings.xml entry "ThreadPoolSizes", the first LLSD-valued settings entry to expect a map: pool name->size. The expectation is that usually code instantiating a particular ThreadPool will have a default size in mind, but it should check "ThreadPoolSizes" for a user override. Make idle_startup()'s STATE_SEED_CAP_GRANTED state instantiate a "General" ThreadPool. This is function-static for lazy initialization. Eliminate LLMainLoopRepeater, which is completely unreferenced. Any potential future use cases are better addressed by posting to the main loop's WorkQueue. Eliminate llappviewer.cpp's private LLDeferredTaskList class, which implemented LLAppViewer::addOnIdleCallback(). Make addOnIdleCallback() post work to the main loop's WorkQueue instead. --- indra/llcommon/CMakeLists.txt | 3 +- indra/llcommon/threadpool.cpp | 75 ++++++++++++++++++++++++++++ indra/llcommon/threadpool.h | 46 +++++++++++++++++ indra/llcommon/timing.cpp | 25 ---------- indra/llcommon/workqueue.cpp | 10 ++++ indra/llcommon/workqueue.h | 5 ++ indra/newview/CMakeLists.txt | 2 - indra/newview/app_settings/settings.xml | 14 ++++++ indra/newview/llappviewer.cpp | 47 +----------------- indra/newview/llmainlooprepeater.cpp | 88 --------------------------------- indra/newview/llmainlooprepeater.h | 64 ------------------------ indra/newview/llstartup.cpp | 18 +++++++ 12 files changed, 171 insertions(+), 226 deletions(-) create mode 100644 indra/llcommon/threadpool.cpp create mode 100644 indra/llcommon/threadpool.h delete mode 100644 indra/llcommon/timing.cpp delete mode 100644 indra/newview/llmainlooprepeater.cpp delete mode 100644 indra/newview/llmainlooprepeater.h (limited to 'indra/llcommon/workqueue.cpp') diff --git a/indra/llcommon/CMakeLists.txt b/indra/llcommon/CMakeLists.txt index fda43dd24c..c374f1135c 100644 --- a/indra/llcommon/CMakeLists.txt +++ b/indra/llcommon/CMakeLists.txt @@ -121,8 +121,8 @@ set(llcommon_SOURCE_FILES lluriparser.cpp lluuid.cpp llworkerthread.cpp - timing.cpp u64.cpp + threadpool.cpp workqueue.cpp StackWalker.cpp ) @@ -258,6 +258,7 @@ set(llcommon_HEADER_FILES lockstatic.h stdtypes.h stringize.h + threadpool.h threadsafeschedule.h timer.h tuple.h diff --git a/indra/llcommon/threadpool.cpp b/indra/llcommon/threadpool.cpp new file mode 100644 index 0000000000..aa7d4179a2 --- /dev/null +++ b/indra/llcommon/threadpool.cpp @@ -0,0 +1,75 @@ +/** + * @file threadpool.cpp + * @author Nat Goodspeed + * @date 2021-10-21 + * @brief Implementation for threadpool. + * + * $LicenseInfo:firstyear=2021&license=viewerlgpl$ + * Copyright (c) 2021, Linden Research, Inc. + * $/LicenseInfo$ + */ + +// Precompiled header +#include "linden_common.h" +// associated header +#include "threadpool.h" +// STL headers +// std headers +// external library headers +// other Linden headers +#include "llerror.h" +#include "llevents.h" +#include "stringize.h" + +LL::ThreadPool::ThreadPool(const std::string& name, size_t threads): + mQueue(name), + mName("ThreadPool:" + name) +{ + for (size_t i = 0; i < threads; ++i) + { + std::string tname{ STRINGIZE(mName << ':' << (i+i) << '/' << threads) }; + mThreads.emplace_back(tname, [this, tname](){ run(tname); }); + } + // Listen on "LLApp", and when the app is shutting down, close the queue + // and join the workers. + LLEventPumps::instance().obtain("LLApp").listen( + mName, + [this](const LLSD& stat) + { + std::string status(stat["status"]); + if (status != "running") + { + // viewer is starting shutdown -- proclaim the end is nigh! + LL_DEBUGS("ThreadPool") << mName << " saw " << status << LL_ENDL; + close(); + } + return false; + }); +} + +LL::ThreadPool::~ThreadPool() +{ + close(); +} + +void LL::ThreadPool::close() +{ + if (! mQueue.isClosed()) + { + LL_DEBUGS("ThreadPool") << mName << " closing queue and joining threads" << LL_ENDL; + mQueue.close(); + for (auto& pair: mThreads) + { + LL_DEBUGS("ThreadPool") << mName << " waiting on thread " << pair.first << LL_ENDL; + pair.second.join(); + } + LL_DEBUGS("ThreadPool") << mName << " shutdown complete" << LL_ENDL; + } +} + +void LL::ThreadPool::run(const std::string& name) +{ + LL_DEBUGS("ThreadPool") << name << " starting" << LL_ENDL; + mQueue.runUntilClose(); + LL_DEBUGS("ThreadPool") << name << " stopping" << LL_ENDL; +} diff --git a/indra/llcommon/threadpool.h b/indra/llcommon/threadpool.h new file mode 100644 index 0000000000..8f3c8514b5 --- /dev/null +++ b/indra/llcommon/threadpool.h @@ -0,0 +1,46 @@ +/** + * @file threadpool.h + * @author Nat Goodspeed + * @date 2021-10-21 + * @brief ThreadPool configures a WorkQueue along with a pool of threads to + * service it. + * + * $LicenseInfo:firstyear=2021&license=viewerlgpl$ + * Copyright (c) 2021, Linden Research, Inc. + * $/LicenseInfo$ + */ + +#if ! defined(LL_THREADPOOL_H) +#define LL_THREADPOOL_H + +#include "workqueue.h" +#include +#include +#include // std::pair +#include + +namespace LL +{ + + class ThreadPool + { + public: + /** + * Pass ThreadPool a string name.

In addition to the name making the blocking explicit, we changed the signature: instead of specifying a target WorkQueue on which to run, waitForResult() runs the passed callable on its own WorkQueue. Why is that? Because, unlike postTo(), we do not require a handshake between two different WorkQueues. postTo() allows running arbitrary callback code, setting variables or whatever, on the originating WorkQueue (presumably on the originating thread). waitForResult() synchronizes using Promise/Future, which are explicitly designed for cross-thread communication. We need not call set_value() on the originating thread, so we don't need a postTo() callback lambda. --- indra/llcommon/workqueue.cpp | 7 +-- indra/llcommon/workqueue.h | 145 ++++++++++++++++++------------------------- 2 files changed, 62 insertions(+), 90 deletions(-) (limited to 'indra/llcommon/workqueue.cpp') diff --git a/indra/llcommon/workqueue.cpp b/indra/llcommon/workqueue.cpp index f7ffc8233c..ac3086aac5 100644 --- a/indra/llcommon/workqueue.cpp +++ b/indra/llcommon/workqueue.cpp @@ -26,11 +26,6 @@ using Mutex = LLCoros::Mutex; using Lock = LLCoros::LockType; -struct NotOnDftCoro: public LLException -{ - NotOnDftCoro(const std::string& what): LLException(what) {} -}; - LL::WorkQueue::WorkQueue(const std::string& name): super(makeName(name)) { @@ -148,6 +143,6 @@ void LL::WorkQueue::checkCoroutine(const std::string& method) // string.
