From 3e60b53d52d09e3f1412a9476743a77e555104d9 Mon Sep 17 00:00:00 2001 From: Cosmic Linden Date: Fri, 6 May 2022 14:46:49 -0700 Subject: SL-16182: Offload audio decoding from the main thread to the general work queue. The work queue callback binds "this". This is deemed safe due to current dependencies, but see the associated comment in the return callback. There was some trial and error to get a this-binded lambda to compile. Due to LLVorbisDecodeState writing to disk off-thread, limit audio decodes proportional to general worker thread count. Guess the thread count for now. --- indra/llcommon/workqueue.h | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'indra/llcommon') diff --git a/indra/llcommon/workqueue.h b/indra/llcommon/workqueue.h index 96574a18b9..70fd65bd0c 100644 --- a/indra/llcommon/workqueue.h +++ b/indra/llcommon/workqueue.h @@ -403,7 +403,7 @@ namespace LL [result = std::forward(callable)(), callback = std::move(callback)] () - { callback(std::move(result)); }; + mutable { callback(std::move(result)); }; } }; @@ -449,7 +449,7 @@ namespace LL callable = std::move(callable), callback = std::move(callback)] () - { + mutable { // Use postMaybe() below in case this originating WorkQueue // has been closed or destroyed.
