eval "exec $4"
Added tests and fixed bugs * Added unit tests for the two Lua interpreter classes * Fixed a bug in checkType() * Have Scribunto_LuaSandboxInterpreter throw an exception on construct when the extension doesn't exist, to match the standalone behaviour. * In Scribunto_LuaSandboxInterpreter, removed debugging statements accidentally left in. * Convert LuaSandboxTimeoutError to the appropriate common error message. * Moved the option munging from the sandbox engine to the interpreter, so that the interpreter can be unit tested separately. * Use /bin/sh instead of bash for lua_ulimit.sh, since dash is smaller and still supports ulimit. * Use exec to run the lua binary, so that the vsize of the shell doesn't add to the memory limit. * Added a quit function to the standalone interpreter. Unused at present. * Don't add a comma after the last element of a table in a Lua expression. * Make the SIGXCPU detection work: proc_open() runs the command via a shell, which reports signals in the child via the exit status, so proc_get_status() will never return a valid termsig element. * In MWServer:call(), fixed a bug causing the return values to be wrapped in an array. * Fixed a misunderstanding of what select() does. * In MWServer:getStatus(), fixed indexes so that vsize will be correct. Removed RSS, since it wasn't used anyway and turns out to be measured in multiples of the page size, and I couldn't be bothered trying to fetch that from getconf. Return the PID and vsize as numbers rather than strings. * Added a simple table dump feature to MWServer:debug(). * Fixed brackets in MWServer:tostring(). * Added missing Linux 32-bit binary.

Introduced standalone interpreter, implemented module isolation * Introduced a Lua implementation based on shelling out to a standard Lua binary. * Bundled several Lua binaries for common platforms. I haven't added a 32-bit Linux binary yet, but that will come. * Refactored the existing Lua class, bringing out functionality common to all Lua implementations into a set of common base classes. * Moved the bulk of the implementation-specific functionality into a set of "interpreter" classes. * Renamed LuaSandboxEngine to Scribunto_LuaSandboxEngine * Don't create an engine object unconditionally when the ParserLimitReport hook is called. * Implemented isolation of module global variable namespaces. This means that separate {{#invoke}} calls can't pass data to each other -- this was a desired feature in planning since it allows more flexibility in wikitext parser design. Isolation for mw.import() means that modules cannot accidentally create global variables which affect other modules -- exports are solely via the return value.
