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.
The bug was so severe that Sony had to apologize for it and send out free copies of other PS2 games to affected players as consolation. [65] Due to a severe programming error, much of the Nintendo DS game Bubble Bobble Revolution is unplayable because a mandatory boss fight failed to trigger in the 30th level. [66]
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).
The ability to detect non-fatal errors is a major distinction between PurifyPlus and similar programs from the usual debuggers.By contrast, debuggers generally only allow the programmer to quickly find the sources of fatal errors, such as a program crash due to dereferencing a null pointer, but do not help to detect the non-fatal memory errors.
Patching also allows for making changes to a program without rebuilding it from source. For small changes, it can be more economical to distribute a patch than to distribute the complete resource. Although often intended to fix problems, a poorly designed patch can introduce new problems (see software regressions). In some cases updates may ...
Usually the compiler will not produce a compiled program even if it manages to parse the entire input text after 'fixing' an error, as the newly 'fixed' program may not be what the programmer intended.
Lint is the computer science term for a static code analysis tool used to flag programming errors, bugs, stylistic errors and suspicious constructs. [1] The term originates from a Unix utility that examined C language source code. [2] A program which performs this function is also known as a "linter".
