UrlLoader not enough memory

Hi.

I'm trying to load files from server with UrlLoader, and somehow "not enough memory" pops up on a certain file.


A source code with actual URL is as follows. (You can download the file at URL.)

--------------------------------------------------

function func(event)
print(#event.data)
end


-- please get rid of -s in the URL. I'm not supposed to post an link here.

loader = UrlLoader.new("http://175.207.4.34/test/test.bin");



loader:addEventListener(Event.COMPLETE,func);

--------------------------------------------------


Using io.read also makes same error. Here is a sample.


--------------------------------------------------

function load(filename)
local file = io.open(filename,"rb")
if file==nil then
return {}
else
local result = file:read("*all")
file:close()
return result
end
end

--------------------------------------------------


I'v tested file's size and a file size is between 5111792 bytes and 5242863 bytes can't be read by UrlLoader.
Once you read the file bigger then 5242863 successfully, you can read a file which size is in the zone (5111792 ~ 5242863) as long as you don't rerun the Gideros player.

    @folded indeed, seems like a bug with a internal buffer size.
    Currently I can't tell if it is on Gideros side or Lua/environment side
    But what you can do instead for now is to read with smaller buffer like:
    local function copy(src, dst)
    	local srcf = io.open(src, "rb")
    	local dstf = io.open(dst, "wb")
    	local size = 2^13      -- good buffer size (8K)
    	while true do
    		local block = srcf:read(size)
    		if not block then break end
    		dstf:write(block)
    	end
    	srcf:close()
    	dstf:close()
    end
    or use lua socket for URLs (attached example, but you may need to re-add lua socket files to project, depending on your OS and Gideros installation path)
