摘要： A script engine for a dynamic language can collect memory allocation information for dynamic objects created by the scripting engine and for dynamic objects created by the script engine host. A native interface can be exposed to a client comprising a software development tool. The software development tool can be a third-party tool. In response to a query, the script engine can take a snapshot of a garbage collector heap and return an object record for each dynamic object in the heap. The object information can include memory allocation information, object type and other information. Multiple snapshots can be taken and the delta between snapshots can be determined and sent to a requestor.

摘要： Methods, systems, and computer program products are provided for profiling source code to enable improved source code execution. A runtime engine includes a parser, a bytecode generator, an execution controller, an interpreter, a just-in-time (JIT) compiler, and a profile generator. The parser receives source code coded in a dynamic language and parses the source code to generate parsed source code. The bytecode generator converts the parsed source code to bytecode. The interpreter is configured to interpret the bytecode when enabled by the execution controller. The JIT compiler is configured to compile the bytecode when enabled by the execution controller. The profile generator generates profile information from the bytecode and stores the profile information. The execution controller enables the interpreter or the JIT compiler to perform their respective functions based on the profile information.
摘要翻译：提供了方法，系统和计算机程序产品，用于分析源代码以实现改进的源代码执行。运行时引擎包括解析器，字节码生成器，执行控制器，解释器，即时（JIT）编译器和简档生成器。解析器接收以动态语言编码的源代码，并解析源代码以生成解析的源代码。字节码生成器将解析的源代码转换为字节码。解释器配置为在执行控制器启用时解释字节码。 JIT编译器配置为在执行控制器启用时编译字节码。配置文件生成器从字节码生成配置文件信息并存储配置文件信息。执行控制器使解释器或JIT编译器能够基于简档信息来执行它们各自的功能。

摘要： Optimized compiled code can be generated from bytecode derived from a program written in a dynamic language such as JavaScript. Optimizations can be based on one or more assumptions. During execution of the optimized compiled code, the assumption or assumptions on which the optimization was based can be examined for validity. In response to determining that the optimization was based on an invalid assumption or assumptions, execution of the optimized code can stop, the state of variables used by an interpreter can be restored and execution of the program can resume in the interpreter using the unoptimized bytecode derived from the program. Resumption of the program can resume at the point in the bytecode analogous to the point in the optimized compiled code at which the assumption or assumptions was determined to be false.
摘要翻译：可以从使用动态语言（如JavaScript）编写的程序派生的字节码生成优化的编译代码。优化可以基于一个或多个假设。在执行优化的编译代码期间，可以检查优化所基于的假设或假设的有效性。响应于确定优化基于无效假设或假设，优化代码的执行可以停止，解释器使用的变量的状态可以被恢复，并且程序的执行可以在解释器中使用未优化的字节码导出从程序。字节码类似于优化编译代码中假设或假设被确定为假的点恢复程序的恢复。
