The following continue to be ignored:
* Generic.Arrays.DisallowLongArraySyntax.Found, because I'm not sure
Scribunto is ready to abandon old version support in master.
* MediaWiki.ControlStructures.AssignmentInControlStructures.AssignmentInControlStructures,
because it's overly strict for its purpose.
Squiz.Classes.ValidClassName.NotCamelCaps isn't ignored globally, we
just ignore it explicitly every place it's needed.

Clean up trailing whitespace from all of our code, and add comments
indicating that apparently unused variables are ScopedCallbacks.

Messages from ScribuntoException are cached and stored with the page, so
they need to be output in the content language.

If an invalid title is entered into MediaWiki:Scribunto-doc-page-name,
it could cause "attempt to call function on a non-object" fatal errors
all over the place. Let's avoid that.

If someone puts something broken in MediaWiki:Scribunto-doc-page-name,
it may not be possible to determine which module the page is a doc page
for. In that case, just pretend it's not a doc page.

It has been claimed that some wiki might want to place module
documentation at a location other than as a subpage of the module, for
example under "Project:Module documentation/$1". It's possible to
support this, so we may as well.
This also involves renaming the "scribunto-doc-subpage-*" messages to
"scribunto-doc-page-*", since the interpretation of
scribunto-doc-subpage-name would be drastically changed.
Note that any wiki that has customized scribunto-doc-subpage-name will
need to re-customize scribunto-doc-page-name, the old value will not be
transferred.

Add the ability for modules to be documented using a /doc subpage, which
is automatically transcluded onto the module page.
To get the transcluding to work right, I wound up having to change from
the deprecated-in-1.21 ArticleViewCustom hook to ContentHandler, as
there didn't seem to be any other way to get the ParserOutput into the
links tables. Which means Scribunto now needs MediaWiki 1.21 rather
than 1.20.

Add a profiler report to the limit report for pages with more than 1s
of Lua time. Uses the profiler introduced in I0b83a914 of LuaSandbox.
Also, fixed some circular references which were preventing the
LuaSandbox object from being destroyed when Scribunto::resetEngine()
was called. Otherwise a large number of interval timers could be started
due to a LuaSandbox object resource leak.

* Added error backtrace collection to MWServer:handleCall()
* When there is an error on parse, show a short and simple inline error
message to the user, which when clicked, expands to a full error with
HTML-formatted backtrace.
* When an error is encountered during module validation, have the code
editor jump directly to the line. Requires r115011.
* Expose the code location of most errors to Scribunto, by parsing the
standard error message format.
* During module validation, abbreviate the error location if the error
is in the same module.
* Do not execute the module during validation, just parse it. Execution
does not really work without an active parse operation in progress.
It already caused a fatal error if you called require() from the main
chunk, and problems would have become more visible as more
parser-related APIs were added.
* LuaSandbox does not yet provide backtraces, but this is planned.

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.
Change-Id: Ie2fd572c362bedf02f45d3fa5352a5280e034740
* 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.
Change-Id: I3fa35651fe5b1fbfd85adeadc220b1ea31cd6f0b
* 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.
* Removed ScriptingEngineBase::load(), inappropriate interface specification, only used by child classes and more properly defined by them
* Fixed inappropriate use of final
* Fixed case of a class constant to conform with MediaWiki conventions
* Use a factory function interface for module creation instead of a class name accessor
* Don't pass unnecessary $engine parameter to ScriptingFunctionBase::__construct(). Pass parent object as the first parameter per convention.
* Fixed unnecessary reference parameter in doRunHook()
* Have LuaSandboxEngineFunction::call() return the first result or null, per the base class documentation, instead of imploding.
* Use strval() to avoid a warning in case call() returns an array or object
* Improved some comments
