I know what it does, but what should my argument be if I'm reading a file and don't know it's maximum size
#What is the max_size argument in std.io.Reader.readAllAlloc?

you chose the maximum length that you are ok with reading. if you really don't want any limit you can use maxInt

If you don't know the length you should use a buffered reader.
buffered reader doesn't change anything about limiting how much data you want to write; it just collates reads together so you don't make a syscall for every byte

you can try to get the file size with
var fsz = (try file.stat()).size;
