Dear Sirs, the script texlive/2018/texmf-dist/scripts/getmap/getmapdl.lua doesn't work anymore. No problems with former versions of TeX Live. It contains the lines local http = require("socket.http"); local ltn12 = require("ltn12") local url = require("socket.url") The luatex version in TL-2018 requires that I change the last line, and *only* the last line to local url = socket.url Otherwise luatex searches socket.url (and only socket.url) in Lua's search path (/usr/local/share/...) without success, though socket.url is already compiled into the binary. Because only socket.url is affected and not socket.http or ltn12 and everything worked in the past, I suppose that socket.url is not registered as a built-in package aymore in current releases of luatex. It seems that package.loaded.socket.url._NAME and package.loaded.socket.url._PACKAGE were removed accidentally.
