mod_bookmarks: Suppress error publishing empty legacy bookmarks w/ no PEP node It appears that when: 1) The user has no bookmarks 2 node in PEP 2) The client publishes an empty bookmark set to a legacy bookmarks location 3) mod_bookmarks will attempt to purge items from the non-existent node and log an error about the failure (item-not-found). This new code will suppress an item-not-found error from the purge operation in the empty-bookmarks case, and adds a log message for any other error (this is helpful because the existing log message confusingly says it was an error *publishing* to the node, which isn't always accurate).

local s_char = string.char;
local s_format = string.format;

local hex_to_char = {};

do
	local char, hex;
	for i = 0,255 do
		char, hex = s_char(i), s_format("%02x", i);
		char_to_hex[char] = hex;
		hex_to_char[hex] = char;
	end
end

local function to(s)
	return (s_gsub(s, ".", char_to_hex));
end

local function from(s)
	return (s_gsub(s_lower(s), "%X*(%x%x)%X*", hex_to_char));
end

return {
	encode = to, decode = from;
	-- COMPAT w/pre-0.12:
	to = to, from = from;
};
