Found via mutation testing.]]> Matthew Wild <mwild1@gmail.com> Tue, 11 Oct 2022 11:38:32 +0100 util.dbuffer: Fix bugs, remove multi-char support (more complex than first thought) http://hg.omfa.de/prosody-hg/log/19cddf92fcc2/spec/util_dbuffer_spec.lua
Character sequences could be split across chunk boundaries. Would require a bunch
of code to make that work reliably.

Only apply front_consumed on first chunk, and adjust buffer_pos accordingly.]]> Matthew Wild <mwild1@gmail.com> Tue, 29 Jun 2021 14:25:57 +0100 util.dbuffer: Add read_until() method http://hg.omfa.de/prosody-hg/log/11e0a0a08da3/spec/util_dbuffer_spec.lua Matthew Wild <mwild1@gmail.com> Tue, 29 Jun 2021 13:48:14 +0100 Merge 0.11->trunk http://hg.omfa.de/prosody-hg/log/3a72cb126d6c/spec/util_dbuffer_spec.lua Kim Alvefur <zash@zash.se> Mon, 12 Oct 2020 21:29:20 +0200 util.dbuffer: Expose length as :len() method, like strings http://hg.omfa.de/prosody-hg/log/a8ef69f7fc35/spec/util_dbuffer_spec.lua

An earlier theory involved the bug being related to collapsing multiple
items, so it exercised that too.

Also correct the comment, it referred to the space in "hello world" in
an earlier version before the test string was changed to "foobar", which
was what was tested in a REPL]]> Kim Alvefur <zash@zash.se> Mon, 24 Aug 2020 17:28:48 +0200 util.dbuffer: Simplify test case http://hg.omfa.de/prosody-hg/log/64713f21ff0e/spec/util_dbuffer_spec.lua

Similar to util.ringbuffer (and shares almost identical API). Differences:

- size limit is optional and dynamic
- does not allocate a fixed buffer of max_size bytes
- focus on simply storing references to existing string objects where possible,
avoiding unnecessary allocations
- references are still stored in a ring buffer to enable use as a fast FIFO

Optional second parameter to new() provides the number of ring buffer segments. On
Lua 5.2 on my laptop, a segment is ~19 bytes. If the ring buffer fills up, the next
write will compact all strings into a single item.]]> Matthew Wild <mwild1@gmail.com> Fri, 26 Jun 2020 16:41:31 +0100
