DBGp
Common DeBugGer Protocol as used by Xdebug and potentially other implementations. DBGp is a simple protocol for use with language tools and engines for the purpose of debugging applications. The protocol provides a means of communication between a debugger engine (scripting engine, Virtual Machine In computing, a virtual machine (VM) is the virtualization/emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardw ..., etc.) and a debugger IDE. Criticisms DBGp has not received widespread adoption as a server protocol. Most implementations are client-side so that IDEs may be compatible specifically with Xdebug, which remains popular. Criticisms have included: * Performance (DBGp is a text-mode protocol) * Security (DBGp has a complex connection mechanism that could lead to buggy vulnerable implementations) * Generality (DBGp is designed to be compatible ...

Xdebug
Xdebug is a PHP extension which provides debugging and profiling capabilities. It uses the DBGp debugging protocol. The debug information that Xdebug can provide includes the following: * stack and function traces in error messages with: :*full parameter display for user defined functions :*function name, file name and line indications :*support for member functions * memory allocation * protection for infinite recursions Xdebug also provides: * profiling information for PHP scripts * code coverage analysis * capabilities to debug your scripts interactively with a debugger front-end. Xdebug is also available via the PECL. See also *Debugger *Dynamic program analysis *Software performance analysis *Optimization *DBG (another open source PHP debugger) *Zend Studio Zend Studio is a commercial, proprietary integrated development environment (IDE) for PHP developed by Zend Technologies, based on the PHP Development Tools (PDT) plugin for the Eclipse platform (the PDT project i ...

Debugger
A debugger or debugging tool is a computer program used to software testing, test and debugging, debug other programs (the "target" program). The main use of a debugger is to run the target program under controlled conditions that permit the programmer to track its execution and monitor changes in computer resources that may indicate malfunctioning code. Typical debugging facilities include the ability to run or halt the target program at specific points, display the contents of memory, CPU registers or storage devices (such as disk drives), and modify memory or register contents in order to enter selected test data that might be a cause of faulty program execution. The code to be examined might alternatively be running on an ''instruction set simulator'' (ISS), a technique that allows great power in its ability to halt when specific conditions are encountered, but which will typically be somewhat slower than executing the code directly on the appropriate (or the same) processor ...

Virtual Machine
In computing, a virtual machine (VM) is the virtualization/emulation of a computer system. Virtual machines are based on computer architectures and provide functionality of a physical computer. Their implementations may involve specialized hardware, software, or a combination. Virtual machines differ and are organized by their function, shown here: * '' System virtual machines'' (also termed full virtualization VMs) provide a substitute for a real machine. They provide functionality needed to execute entire operating systems. A hypervisor uses native execution to share and manage hardware, allowing for multiple environments which are isolated from one another, yet exist on the same physical machine. Modern hypervisors use hardware-assisted virtualization, virtualization-specific hardware, primarily from the host CPUs. * Process virtual machines are designed to execute computer programs in a platform-independent environment. Some virtual machine emulators, such as QEMU and video ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrated Development Environment
An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of at least a source code editor, build automation tools and a debugger. Some IDEs, such as NetBeans and Eclipse, contain the necessary compiler, interpreter, or both; others, such as SharpDevelop and Lazarus, do not. The boundary between an IDE and other parts of the broader software development environment is not well-defined; sometimes a version control system or various tools to simplify the construction of a graphical user interface (GUI) are integrated. Many modern IDEs also have a class browser, an object browser, and a class hierarchy diagram for use in object-oriented software development. Overview Integrated development environments are designed to maximize programmer productivity by providing tight-knit components with similar user interfaces. IDEs present a single program i ...

Communications Protocols
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation. The specified behavior is typically independent of how it is to be implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there is a close analogy between protocols and programming languages: ''protocols are to co ...
