From e79acaeb750ba286786ad122ddf20e9c179c19cf Mon Sep 17 00:00:00 2001 From: Matt Jordan Date: Fri, 4 Nov 2016 15:42:09 -0500 Subject: [PATCH] res_http_websocket: Increase the buffer size for non-LOW_MEMORY systems Not surprisingly, using Respoke (and possibly other systems) it is possible to blow past the 16k limit for a WebSocket packet size. This patch bumps it up to 32k, which, at least for Respoke, is sufficient. For now. Because 32k is laughable on a LOW_MEMORY system (as is 16k, for that matter), this patch adds a LOW_MEMORY directive that sets the buffer to 8k for systems who have asked for their reduced memory availability to be considered.
