Hi, first of all, thank you very much for LuaTeX Version 1.0.
However, when I load a complete file into memory

fd=io.open(file, "r") local t = fd:read("*a") fd:close() ----------------------------------
I get
$ texlua testmem.lua f_256MiB $ luajittex --luaonly testmem.lua f_256MiB $ texlua testmem.lua f_512MiB $ luajittex --luaonly testmem.lua f_512MiB not enough memory
It seems that luajit limits the size of a file being read for some reason. I'm puzzled because I do not see any relationship between loading a file into memory and just-in-time compilation.
Is it possible to increase this limit, at least? It would be nice if everything which can be done with luatex could be done with luajittex as well.
There are more limitations in luajit due to the different implementation of the vm (one reason why it's faster). You will hit these with large data sets, so you can only use luajittex in well known situations (which is the majority).
