Automatic bug fixing is made according to a specification of the expected behavior which can be for instance a formal specification or a test suite. [5]A test-suite – the input/output pairs specify the functionality of the program, possibly captured in assertions can be used as a test oracle to drive the search.
Many resource leaks are fixed by resource reclamation by the operating system after the process terminates and makes an exit system call. Resource leaks are thus primarily a problem for long-lived processes, as leaked resources held by still-running processes are often not reclaimed; and for processes that rapidly acquire and leak many resources.
Resource leaks may happen under regular program flow – such as simply forgetting to release a resource – or only in exceptional circumstances, such as when a resource is not released if there is an exception in another part of the program. Resource leaks are very frequently caused by early exit from a subroutine, either by a return ...
A software bug is a design defect in computer software.A computer program with many or serious bugs may be described as buggy.. The effects of a software bug range from minor (such as a misspelled word in the user interface) to severe (such as frequent crashing).
This utility modifies the target program's executable file—the program's machine code—typically by overwriting its bytes with bytes representing the new patch code. If the new code will fit in the space (number of bytes) occupied by the old code, it may be put in place by overwriting directly over the old code. This is called an inline patch.

A hotfix is a software update that is released outside the normal update cycle or intended to be applied to a live system; often to fix a bug. [1] Originally, hotfix referred to patching a hot system – a production server that is actively serving clients. For development, such a change usually must be designed quickly and outside normal ...
A patch release (often colloquially also known as a point release, dot release, or bugfix release) is a software release of a product or other project, especially one intended to fix bugs or do small cleanups rather than add significant features. Often, there are too many bugs to be fixed in a single major or minor release, creating a need for ...
