From dacc5afbf0f1bde7454c1eadf56edb669d0741a9 Mon Sep 17 00:00:00 2001 From: Monroe Linden Date: Tue, 27 Apr 2010 17:25:01 -0700 Subject: Architectural changes to LLPlugin message processing. LLPluginProcessParent can now optionally use a separate thread for reading messages from plugin sockets. If this is enabled, it will spawn a single thread and use apr_pollset_poll to wake up the thread when incoming data arrives instead of polling all the descriptors round-robin every frame. This should be somewhat more efficient, and should also allow blocking requests from plugins to be serviced much more quickly (once we start using them). This is currently disabled by default, until it's had a bit more focused testing on multiple platforms. Hooked up the switch to use the message read thread to the PluginUseReadThread debug setting and an item in the Advanced menu in the viewer, and to a checkbox in the UI in llmediaplugintest. Updated some debug logging in the plugin system to have appropriate tags and not log dire-looking warnings during normal operation. LLPluginProcessParent now once again explicitly kills plugin processes (instead of just closing their sockets and waiting for them to exit). The problem we were attempting to solve by not doing the kill (letting the webkit plugin write its cookie file on exit) has been solved another way. LLPluginProcessParent::sendMessage() now attempts to write the outgoing message to the socket immediately instead of waiting for the next frame. This should reduce the latency of sending plugin messages. Added a separate fast timer for LLViewerMedia::updateMedia(). --- indra/newview/app_settings/settings.xml | 13 +++++++++++++ indra/newview/llappviewer.cpp | 3 +++ indra/newview/llviewermedia.cpp | 11 +++++++++++ indra/newview/skins/default/xui/en/menu_viewer.xml | 10 ++++++++++ 4 files changed, 37 insertions(+) (limited to 'indra/newview') diff --git a/indra/newview/app_settings/settings.xml b/indra/newview/app_settings/settings.xml index 6f11a6d616..280c3d642c 100644 --- a/indra/newview/app_settings/settings.xml +++ b/indra/newview/app_settings/settings.xml @@ -5585,6 +5585,19 @@ Value 8 + + PluginUseReadThread + + Comment + Use a separate thread to read incoming messages from plugins + Persist + 1 + Type + Boolean + Value + 0 + + PrecachingDelay Comment diff --git a/indra/newview/llappviewer.cpp b/indra/newview/llappviewer.cpp index 2f9bbb1407..4f7c0c3549 100644 --- a/indra/newview/llappviewer.cpp +++ b/indra/newview/llappviewer.cpp @@ -1530,6 +1530,9 @@ bool LLAppViewer::cleanup() LLViewerMedia::saveCookieFile(); + // Stop the plugin read thread if it's running. + LLPluginProcessParent::setUseReadThread(false); + llinfos << "Shutting down Threads" << llendflush; // Let threads finish diff --git a/indra/newview/llviewermedia.cpp b/indra/newview/llviewermedia.cpp index fd2bb0fdf9..8e210554fb 100644 --- a/indra/newview/llviewermedia.cpp +++ b/indra/newview/llviewermedia.cpp @@ -732,10 +732,21 @@ static bool proximity_comparitor(const LLViewerMediaImpl* i1, const LLViewerMedi } } +static LLFastTimer::DeclareTimer FTM_MEDIA_UPDATE("Update Media"); + ////////////////////////////////////////////////////////////////////////////////////////// // static void LLViewerMedia::updateMedia(void *dummy_arg) { + LLFastTimer t1(FTM_MEDIA_UPDATE); + + bool use_read_thread = gSavedSettings.getBOOL("PluginUseReadThread"); + if(LLPluginProcessParent::getUseReadThread() != use_read_thread) + { + // Enable/disable the plugin read thread + LLPluginProcessParent::setUseReadThread(use_read_thread); + } + sAnyMediaShowing = false; sUpdatedCookies = getCookieStore()->getChangedCookies(); if(!sUpdatedCookies.empty()) diff --git a/indra/newview/skins/default/xui/en/menu_viewer.xml b/indra/newview/skins/default/xui/en/menu_viewer.xml index 3af80f63fe..df4f33adf0 100644 --- a/indra/newview/skins/default/xui/en/menu_viewer.xml +++ b/indra/newview/skins/default/xui/en/menu_viewer.xml @@ -1339,6 +1339,16 @@ function="ToggleControl" parameter="RunMultipleThreads" /> + + + + -- cgit v1.3 From 77b13dc2df679c46f648a4f99c8e4d8836983a48 Mon Sep 17 00:00:00 2001 From: Monroe Linden Date: Thu, 29 Apr 2010 17:33:37 -0700 Subject: Incorporate suggestions from Richard's review of the LLPlugin changes. Use LLMutexLock (stack-based locker/unlocker) for the straightforward cases instead of explicit lock()/unlock(). There are still a couple of cases (one overlapping lock lifetime and two loops that unlock the mutex to call another function inside the loop) where I'm leaving explicit lock/unlock calls. Rename LLPluginProcessParent::sPollThread to sReadThread, for consistency. Made the LLPluginProcessParent destructor hold mIncomingQueueMutex while removing the instance from the global list -- this should prevent a possible race condition in LLPluginProcessParent::poll(). Removed a redundant check when calling LLPluginProcessParent::setUseReadThread(). --- indra/llplugin/llpluginmessagepipe.cpp | 9 ++-- indra/llplugin/llpluginprocessparent.cpp | 78 +++++++++++++++++--------------- indra/llplugin/llpluginprocessparent.h | 2 +- indra/newview/llviewermedia.cpp | 8 +--- 4 files changed, 48 insertions(+), 49 deletions(-) (limited to 'indra/newview') diff --git a/indra/llplugin/llpluginmessagepipe.cpp b/indra/llplugin/llpluginmessagepipe.cpp index a62534de95..89f8b44569 100644 --- a/indra/llplugin/llpluginmessagepipe.cpp +++ b/indra/llplugin/llpluginmessagepipe.cpp @@ -117,10 +117,9 @@ LLPluginMessagePipe::~LLPluginMessagePipe() bool LLPluginMessagePipe::addMessage(const std::string &message) { // queue the message for later output - mOutputMutex.lock();
