 Static code analysis - Wikipedia, the free encyclopedia
Static analysis is the term applied to the analysis of computer software that is performed without actually executing programs built from that software (analysis performed on executing programs is known as dynamic analysis).
In most cases the analysis is performed on some version of the source code and in the other cases some form of the object code.
A growing commercial use of static analysis is in the verification of properties of software used in safety-critical computer system.

 Encyclopedia: Static code analysis
Static code analysis is a set of methods for software source code or object code in an effort to gain understanding of what the software does.
Static analysis is a family of formal methods automatically deriving information about the behavior of software (and also hardware).
Interest in the development of static analysis especially for use on safety-critical computer systems renewed after the high profile disaster of Ariane 5 Flight 501 when a space rocket exploded shortly after launch due to computer bug surely one of the most expensive bugs in history.

One possible application of static analysis is automated debugging aid, especially the finding of run-time errors – roughly speaking, events causing program crashes.
Briefly, program analysis — including finding possible run-time errors – is undecidable: there is no mechanical method that can always answer truthfully whether programs may or not exhibit runtime errors.

Static analysis is commonly referred to as code analysis, as the analysis is performed statically by analyzing the source code where as dynamic analysis is performed while executing the executable code, hence “dynamic analysis”.
An emerging role of code analysis is with its importance for information assurance and the building of assurance cases.
Code analysis can also be used to address design concerns, conformance to project coding/quality standards, performance issues, and maintenance issues.

 STSC CrossTalk - Software Static Code Analysis Lessons Learned© - Nov 2003
Static analysis does not prove that the requirements the code was developed from were correct or show that the compiled code is correct.
Object code analysis demonstrates that the object code is an accurate translation of the source code and that the compiler has introduced no errors.
Static code analysis is an effective software analysis technique; hence, its use is recommended in the context of safety-critical software particularly when conducted constructively as part of the software development process.

Given that code reviews can be effective at locating software defects during development when they are most easily and inexpensively fixed, it makes sense to automate this process as much as possible.
PMD is a static source code analysis tool, meaning that it analyzes source code lexically rather than by executing it as would be done in a unit test.

 DAC Analysis for Symbols
Static analysis for symbols is the DAC "engine" because almost all other DAC functionalities depend on it.
Static analysis, which is based on the same principles as a compiler or linker, extracts all information on symbols from the source code of the user project (functions, variables, constants, types, macros) and saves them in the symbol database.
DAC version 4.0 has the advantage that the assembler code is analyzed along with the C source code, so the usefulness of this hidden yet powerful functionality is all the greater.

 Klocwork | News ~ Static Analysis All the Rage
It was a static code checker that would scan through codebases written in C looking for programming infelicities, and then it would generate appropriate error reports.
But to be fair, the compiler’s job is not to perform static code analysis to identify potential errors for the programmer; its job is to generate binary code, and to do it fast.
This analysis is based on the assumption that any data provided by a user (be it on the command line, in a dialog box or via the Web) is malicious.

 Evaluating Source Code Analysis Tools
Static analysis tools are capable of detecting potential faults in C source code prior to execution-based testing.
Faults such as unreachable code or a missing response to a valid combination of conditions might be detected by a static analysis tool.
As a result, it was reasonable to conclude that this code would have the same types and density of faults as would be found in other user applications from this domain.

Static code analysis refers to a set of methods for analysing software source code in an effort to gain understanding and to target areas for review and/or rewrite.
One of the crudest measurments, for example, is the size of code, usually expressed in kLOC's (1000 lines of code).

 Jtest promotes good Java hygiene | InfoWorld | Review | 2003-12-12 | By Rick Grehan
The former is more properly called static analysis and involves examining your code for errors in syntax, style, standard, and usage, and other characteristics.
Static analysis is driven by Jtest's library of rules, of which there are two general kinds: those that apply to specific Java constructs (such as EJBs or servlets) and those that apply to generic Java code (such as metrics or formatting).
Jtest examines your code’s generated class file, and – from the information it gathers – performs global static analysis to catch “soft errors” and poor coding practices, such as class fields that are never accessed.

 Independent Design Analyses Approach Vs. Static Code Analysis
Static code analysis can identify unreachable code, infinite loops, initialization errors, code complexity, and output variable ranges that could generate a logic problem.
Most of the static analysis techniques use an intermediate language interpreter that translates the computer language written by the programmer into a language used by the analysis tool.
After the software code is translated into the intermediate language or IL, the IL is processed and reports are generated.

The objective of dynamic analysis is to reduce debugging time by automatically pinpointing and explaining errors as they occur.
The use of dynamic analysis tools can reduce the need for the developer to recreate the precise conditions under which an error occurs.
Identifying problems at the source code level with static source code analysis can further reduce the time and expense of other debugging tactics by allowing developers to identify and eradicate problems at the source code level, prior to compiling.

 Automated Error Prevention
Coding standards are language-specific 'rules' that significantly reduce the chance for developers to introduce errors.
Coding standards do not uncover existing problems, rather they actually prevent errors from occurring.

As a result of a powerful data flow analysis, IntelliJ IDEA will find such «suspicious» places in implementation code that might lead to problems such as a never executed if statement (when, for example, its condition is always false), possible NullPointerException, etc.
All common syntax errors, as well as all other errors that would be detected during compilation, are highlighted in the source code so you do not need to compile your code in order to find all your mistakes.
If any deprecated code is used in any class or interface, IntelliJ IDEA will recognize it and highlight the corresponding statements directly in the editor.
