摘要： A software tool includes logic configured to enable a child process that inherits the address space of a modified parent process to execute an unaltered version of the address space when the child process inherits the altered address space of the parent process. A method for processing breakpoint events in a child process created from a parent process, when the parent process is modified by a software tool includes, storing unmodified parent process code replaced by each occurrence of a breakpoint inserted into the address space during modification of the parent process, monitoring execution of a child process created by the parent process for an initial breakpoint in the address space, suspending execution of the child process in response to an initial breakpoint, replacing each occurrence of a breakpoint in the address space with the unmodified parent process code, and resuming execution of the child process.

摘要： A monitoring interface, includes logic responsive to a pre-fork event, the pre-fork event responsive to a vfork system call. The pre-fork event includes indicia that identifies a child process to be created in accordance with the vfork system call. A method for controlling the execution of a child process created from a parent process, where the parent process is monitored by a software tool includes, receiving indicia that a vfork system call will be executed by the parent process, suspending execution of the parent process, extracting a process identifier from the indicia of the vfork system call, the process identifier corresponding to a child process to be generated by the parent process when the parent process executes the vfork system call, setting a process monitor thread to observe the child process, and resuming execution of the parent process to enable the parent process to execute past the vfork system call.

摘要： A method, and a corresponding system, for dynamically updating software while the software is running by automatically dividing a patch into a plurality of micro-updates using compiler analysis. The method includes providing the patch which includes updates to several variable units of the software, including functions, type definitions, and data stores. Next, an interference graph of the patch is generated by creating a node corresponding to each variable unit of the patch and creating connected components by adding edges connecting variable units having an impact expression with a non-zero intersection. The patch is divided into the micro-updates, where each micro-update corresponds to a connected component. The micro-updates are then applied to the software when the variable units of the micro-update are at a safepoint, and at least two of the micro-updates are applied at different times while the software is running.
