If the buffer was full, find() would return earlier (wpos == rpos). Checking
blen is the better way to test if the buffer is empty.

Secondly, the loop scanned for blen - l, but if l (length of needle) was
larger than the buffer length, this calculation would underflow and cause a
lot of spinning.

New tests have been added to cover various edge cases of :find().]]> Matthew Wild <mwild1@gmail.com> Mon, 25 May 2026 14:44:20 +0100 util.ringbuffer: Fix incorrect returned position from :find() for #needle~=1 http://hg.omfa.de/prosody-hg/log/2bcabbeac9b0/spec/util_ringbuffer_spec.lua
