Added more Lua environment features Package library: * Added a simulation of the Lua 5.1 package library. * Removed mw.import(), replaced it with a package loader. Packages can be retrieved from the wiki, using require('Module:Foo'), or from files distributed with Scribunto, using require('foo'). The "Module:" prefix allows for source compatibility with existing Lua code. * Added a couple of libraries from LuaForge: luabit and stringtools. * Made fetchModuleFromParser() return null on error instead of throwing an exception, to more easily support the desired behaviour of the package loader, which needs to return null on error. * Renamed mw.setupEnvironment() to mw.setup() since it is setting up things other than the environment now. * In MWServer:handleRegisterLibrary(), remove the feature which interprets dots in library names, since LuaSandbox doesn't support this. Improved module isolation and related refactoring: * Expose restricted versions of getfenv() and setfenv() to user Lua code. Requires luasandbox r114952. * Don't cache the export list returned by module execution for later function calls. This breaks isolation of #invoke calls, since the local variables are persistent. * Removed ScribuntoFunctionBase and its children, since it doesn't really have a purpose if it can't cache anything. Instead, invoke functions using a module method called invoke(). * Removed Module::initialize(), replaced it with a validate() function. This is a more elegant interface and works better with the new module caching scheme. * Use a Status object for the return value of Engine::validate() instead of an array. Use the formatting facilities of the Status class. Other: * Removed "too many returns" error, doesn't fit in with Lua conventions. * Use the standalone engine by default, so that the extension will work without configuration for more people. * Added an accessor for $engine->interpreter * Fix mw.clone() to correctly clone metatables * If the standalone interpreter exits due to an error, there are some contexts where the initial error will be caught and ignored, and the user will see the error from checkValid() instead. In this case, rethrow the original error for a more informative message. * Load mw.lua into the initial standalone environment, to reduce code duplication between mw.lua and MWServer.lua. * Fixed a bug in Scribunto_LuaStandaloneInterpreter::handleCall() for functions that return no results. * Fixed a bug in encodeLuaVar() for strings with "\r". Added test case. * In MWServer.lua, don't call error() for internal errors, instead just print the error and exit. This avoids a protocol violation when an error is encountered from within handleCall(). * Added lots of documentation. Lua doc comments are in LuaDoc format.

* Removed scriptlinks table. It just seemed the same as templatelinks to me, and tl_namespace can be used if you want to separate out modules. * Used Parser::fetchTemplateAndTitle() to get modules and register them in templatelinks. Most of the logic was previously duplicated. * Changed the configuration and factory functions to allow for the possibility of multiple engines coexisting on the one wiki. * Made the $parser parameter optional, to improve debugging in the case where a parser is needed but parsing has not started. Removed all $wgParser references. * Renamed Scripting::getEngine() to getParserEngine() and resetEngine() to resetParserEngine() * Removed setOptions() and updateOptions(). If you want to change the options, you can always make a new instance. * Renamed getModule() to fetchModuleFromParser() * Simplified module constructor parameters and member variable list * Fixed spelling error langauge -> language * Renamed a few variables for clarity: $module -> $moduleName, $function -> $functionName * Renamed getLimitsReport() to getLimitReport() as it is in Parser * Use an accessor for getting LuaSandboxEngineModule::$contents * Renamed configuration variable maxCPU to cpuLimit * Include the full message name as a parameter to ScriptingException. This makes it easier to find messages in the i18n file, and it makes it easier to find invocation points when a translator wants to know how a message is used. Adding the message name as a comment on the same line seems like a waste of space when you can just make it an actual parameter. * Reduce the number of formal parameters to ScriptingException::__construct(), since there is already too many and we may want to add more things later, such as backtraces with hyperlinks and other such stuff. * Include the code location as $2 unconditionally so that there is less chance of getting the parameters wrong * Shortened some message names. Wrote English text for messages without it.
