Preliminary step toward dynamic recompilation: Standardized and
simplified the parsing interface.


The main goal in this patch is to make it easy to ask for a duplicate
compilation, and get back a duplicate result -- same source URL, same
debugger / profiler ID, same toString behavior, etc.


The basic unit of compilation and evaluation is now SourceCode, which
encompasses a SourceProvider, a range in that provider, and a starting
line number.

A SourceProvider now encompasses a source URL, and *is* a source ID,
since a pointer is a unique identifier.

  • API/JSBase.cpp: (JSEvaluateScript): (JSCheckScriptSyntax): Provide a SourceCode to the Interpreter, since other APIs are no longer supported.


  • VM/CodeBlock.h: (JSC::EvalCodeCache::get): Provide a SourceCode to the Interpreter, since other APIs are no longer supported. (JSC::CodeBlock::CodeBlock): ASSERT something that used to be ASSERTed by our caller -- this is a better bottleneck.
  • VM/CodeGenerator.cpp: (JSC::CodeGenerator::CodeGenerator): Updated for the fact that FunctionBodyNode's parameters are no longer a WTF::Vector.
  • kjs/Arguments.cpp: (JSC::Arguments::Arguments): ditto
  • kjs/DebuggerCallFrame.cpp: (JSC::DebuggerCallFrame::evaluate): Provide a SourceCode to the Parser, since other APIs are no longer supported.
  • kjs/FunctionConstructor.cpp: (JSC::constructFunction): Provide a SourceCode to the Parser, since other APIs are no longer supported. Adopt FunctionBodyNode's new "finishParsing" API.
  • kjs/JSFunction.cpp: (JSC::JSFunction::lengthGetter): (JSC::JSFunction::getParameterName): Updated for the fact that FunctionBodyNode's parameters are no longer a wtf::Vector.
  • kjs/JSFunction.h: Nixed some cruft.
  • kjs/JSGlobalObjectFunctions.cpp: (JSC::globalFuncEval): Provide a SourceCode to the Parser, since other APIs are no longer supported.
  • kjs/Parser.cpp: (JSC::Parser::parse): Require a SourceCode argument, instead of a bunch of broken out parameters. Stop tracking sourceId as an integer, since we use the SourceProvider pointer for this now. Don't clamp the startingLineNumber, since SourceCode does that now.
  • kjs/Parser.h: (JSC::Parser::parse): Standardized the parsing interface to require a SourceCode.
  • kjs/Shell.cpp: (functionRun): (functionLoad): (prettyPrintScript): (runWithScripts): (runInteractive): Provide a SourceCode to the Interpreter, since other APIs are no longer supported.
  • kjs/SourceProvider.h: (JSC::SourceProvider::SourceProvider): (JSC::SourceProvider::url): (JSC::SourceProvider::asId): (JSC::UStringSourceProvider::create): (JSC::UStringSourceProvider::UStringSourceProvider): Added new responsibilities described above.
  • kjs/SourceRange.h: (JSC::SourceCode::SourceCode): (JSC::SourceCode::toString): (JSC::SourceCode::provider): (JSC::SourceCode::firstLine): (JSC::SourceCode::data): (JSC::SourceCode::length): Added new responsibilities described above. Renamed SourceRange to SourceCode, based on review feedback. Added a makeSource function for convenience.
  • kjs/debugger.h: Provide a SourceCode to the client, since other APIs are no longer supported.
  • kjs/grammar.y: Provide startingLineNumber when creating a SourceCode.
  • kjs/debugger.h: Treat sourceId as intptr_t to avoid loss of precision on 64bit platforms.
  • kjs/interpreter.cpp: (JSC::Interpreter::checkSyntax): (JSC::Interpreter::evaluate):
  • kjs/interpreter.h: Require a SourceCode instead of broken out arguments.
  • kjs/lexer.cpp: (JSC::Lexer::setCode):
  • kjs/lexer.h: (JSC::Lexer::sourceRange): Fold together the SourceProvider and line number into a SourceCode. Fixed a bug where the Lexer would accidentally keep alive the last SourceProvider forever.
  • kjs/nodes.cpp: (JSC::ScopeNode::ScopeNode): (JSC::ProgramNode::ProgramNode): (JSC::ProgramNode::create): (JSC::EvalNode::EvalNode): (JSC::EvalNode::generateCode): (JSC::EvalNode::create): (JSC::FunctionBodyNode::FunctionBodyNode): (JSC::FunctionBodyNode::finishParsing): (JSC::FunctionBodyNode::create): (JSC::FunctionBodyNode::generateCode): (JSC::ProgramNode::generateCode): (JSC::FunctionBodyNode::paramString):
  • kjs/nodes.h: (JSC::ScopeNode::): (JSC::ScopeNode::sourceId): (JSC::FunctionBodyNode::): (JSC::FunctionBodyNode::parameterCount): (JSC::FuncExprNode::): (JSC::FuncDeclNode::): Store a SourceCode in all ScopeNodes, since SourceCode is now responsible for tracking URL, ID, etc. Streamlined some ad hoc FunctionBodyNode fixups into a "finishParsing" function, to help make clear what you need to do in order to finish parsing a FunctionBodyNode.
  • wtf/Vector.h: (WTF::::releaseBuffer): Don't ASSERT that releaseBuffer() is only called when buffer is not 0, since FunctionBodyNode is more than happy to get back a 0 buffer, and other functions like RefPtr::release() allow for 0, too.

We still treat sourceId as int in some cases because of DashCode. See
<rdar://problem/6263293> WebScriptDebugDelegate should use intptr_t for
sourceId, not int.
