More Information
Summary:Techniques are disclosed for concurrently loading a plurality of new modules while code of a plurality of modules of an original computer program is loaded and executed on a computer system. An associated method may include allocating a module thread local storage (TLS) block for each thread within an initial computer program, wherein the allocated module TLS blocks are large enough to hold all module thread variables that are loaded or to be loaded. The method further may include reserving spare areas between the module TLS blocks for adding new module thread variables and arranging at an end of the module TLS blocks a thread data template section for resetting threads or creating new threads. The method may result in addition of modules to the original computer program and/or application of a concurrent patch through replacement of one or more of the plurality of original computer program modules.
