Abstract: A data processing method, performed by a processor, includes obtaining executable code generated by compiling source code. The executable code includes code corresponding to an extension instruction, where the extension instruction indicates that target data needs to reside in a cache, and the target data is data to be invoked for a plurality of times in a process of executing the executable code. The method further includes executing the executable code, obtaining the target data, and storing the target data in the cache. The executable code obtained by the processor directly carries the extension instruction, and the processor executes the code corresponding to the extension instruction, so that the target data may reside in the cache.

Abstract: A scheduler obtains a to-be-processed job; and controls at least one super node based on a resource requirement of the to-be-processed job to process the to-be-processed job based on a global memory pool of the super node, where the to-be-processed job is a processing request related to a distributed application. In this way, because the global memory pool is a resource that is constructed through unified addressing on storage media of nodes in the super node and that is shared by the nodes in the super node, the nodes in the super node that are coupled using a high-speed interconnection technology share and access the global memory pool to process the to-be-processed job.

Abstract: Provided is a code translation method. The method includes: obtaining first code, where the first code is written based on a platform-dependent language of a source platform, then determining at least one translation rule that matches the first code, where the translation rule is used to directly translate code of one platform into code of another platform, and then translating the first code by using the translation rule, to obtain second code applicable to a target platform. This method implements automatic cross-platform translation of code by using the translation rule, and improves translation efficiency and translation accuracy.

Abstract: A code processing method includes: obtaining first code, where the first code is code that is obtained through compilation and that is applicable to a source platform; then relocating addresses of variables associated with functions in the first code, to obtain logical addresses of the variables; and then performing decompilation based on the logical addresses of the variables and the first code, to obtain second code applicable to a target platform.

Abstract: This application discloses code processing methods, apparatuses, and storage media. An example method includes: obtaining a first code in low-level language and applicable to a source platform; decompiling the obtained first code to obtain an intermediate representation (IR); and then compiling the IR into a second code in low-level language and applicable to a first target platform, where the source platform and the target platform have different instruction sets.

Abstract: In a cross-platform code conversion method, a conversion device obtains first source code that is configured to run on a first platform. The conversion device performs syntactic analysis on the first source code to generate a syntax tree corresponding to the first source code, and identifies a to-be-converted syntax block in the syntax tree according to a syntax rule provided by a rule library. The conversion device converts the to-be-converted syntax block according to a conversion rule provided by the rule library to obtain a converted syntax block. The conversion device then generates, based on the obtained converted syntax block, second source code for running on a second platform.

Abstract: An improved anti-malware protection system protects computers against exploits in a scripting language that may be run in a browser. The system comprises a recorder that records scripting language execution events, a trace generator that transforms the recorded scripting language execution events into an execution trace, and a security engine that scans the execution trace and advises a security software about exploits found in the execution trace. By hooking the recorder into a runtime application programming interface for the scripting language, the improved protection system can detect exploits dynamically without the need for a browser-dependent plugin. An optional plugin can be included to perform file-based analysis of the script in addition to the runtime analysis of the script. The system can provide an application programming interface that can be used by multiple security software programs from multiple vendors to create an enhanced security software product.

Abstract: Technologies are presented that allow application events to be recorded and replayed in a reliable and deterministic manner. A computing system may include a memory and a processor communicatively coupled with the memory. The processor may execute application logic of an application, record events associated with the application based on invocation of functions associated with the events, and store the recorded events in the memory for future playback. Recorded events may include, for example, user interactions, timing events, network downloads, callbacks, web worker tasks, etc. The recording of the events may include recording top-level functions of each event according to their order, and recording associated data including function parameters and/or return values. The recorded events may be replayed in order using the recorded associated data while suppressing non-recorded events.

In some embodiments, a graphical element in a frame, application, or web page, which is to be presented to a user via a web browser, is rendered either by a first processor or a second processor based on indications of whether the first or the second processor is equipped or configured to provide faster rendering. A rendering engine may utilize either processor based on historical or anticipated rendering performance, and may dynamically switch between the hardware decoder and general purpose processor to achieve rendering time performance improvement. Switches between processors may be limited to a fixed number switches or switching frequency.
