Kim Alvefur	43531740f9	util: Prefix module imports with prosody namespace	3 years ago
Matthew Wild	ffa72d829b	util.dbuffer: Add efficient shortcuts for discard() in certain cases ... If the buffer is already empty, nothing to do. If we're throwing away the whole buffer, we can just empty it and avoid read_chunk() (which in turn may collapse()). These shortcuts are much more efficient.	3 years ago
Matthew Wild	586a0d8493	util.dbuffer: Remove redundant code (read_chunk() cannot fail at this point)	3 years ago
Matthew Wild	01c5bf5529	util.dbuffer: Optimize :sub() and :byte()	5 years ago
Kim Alvefur	d3b3e21720	util.dbuffer: Expose length as :len() method, like strings ... Ref #1598	5 years ago
Matthew Wild	91d42d3218	util.dbuffer: Fix :sub() not working with partially-consumed chunks (thanks Zash for test case) ... This also appears to fix some bugs with chunk-encoded streams in net.http.parser.	5 years ago
Matthew Wild	e21e4b2b24	util.dbuffer: Fix bugs, remove multi-char support (more complex than first thought) ... 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.	5 years ago
Matthew Wild	4e56658eb3	util.dbuffer: Add read_until() method	5 years ago
Matthew Wild	f80e643a0e	util.dbuffer: Add __name to metatable	5 years ago
Matthew Wild	7fa4cc8de0	util.dbuffer: Fix :sub() not working with partially-consumed chunks (thanks Zash for test case) ... This also appears to fix some bugs with chunk-encoded streams in net.http.parser.	5 years ago
Matthew Wild	9115d2a366	util.dbuffer: Fix traceback when :collapse() is called on empty buffer	5 years ago
Matthew Wild	67cf276ba2	util.dbuffer: If no bytes parameter passed to read, return remainder of frontmost chunk	6 years ago
Matthew Wild	fb8e10737d	util.dbuffer: dynamic string buffer ... 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.	6 years ago
