From 11afa09ea3f56c0e20eb195ae1520a88602ceaca Mon Sep 17 00:00:00 2001 From: Nat Goodspeed Date: Fri, 22 Oct 2021 11:36:31 -0400 Subject: SL-16220: Add LL::ThreadPool class and a "General" instance. 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/newview/llmainlooprepeater.cpp | 88 ------------------------------------ 1 file changed, 88 deletions(-) delete mode 100644 indra/newview/llmainlooprepeater.cpp (limited to 'indra/newview/llmainlooprepeater.cpp') diff --git a/indra/newview/llmainlooprepeater.cpp b/indra/newview/llmainlooprepeater.cpp deleted file mode 100644 index 6736e9a950..0000000000 --- a/indra/newview/llmainlooprepeater.cpp +++ /dev/null @@ -1,88 +0,0 @@ -/** - * @file llmachineid.cpp - * @brief retrieves unique machine ids - * - * $LicenseInfo:firstyear=2009&license=viewerlgpl$ - * Second Life Viewer Source Code - * Copyright (C) 2010, Linden Research, Inc. - * - * This library is free software; you can redistribute it and/or - * modify it under the terms of the GNU Lesser General Public - * License as published by the Free Software Foundation; - * version 2.1 of the License only. - * - * This library is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Reverting a merge is sticky: it tells git you never want to see that branch again. Merging the DRTVWR-546 branch, which contained the revert, into the glthread branch undid much of the development work on that branch. To restore it we must revert the revert.
