Network timeout preventing a Web browser from loading a page. In telecommunications and related engineering (including computer networking and programming), the term timeout or time-out has several meanings, including: A network parameter related to an enforced event designed to occur at the conclusion of a predetermined elapsed time.
C# provides the lock keyword on a thread to ensure its exclusive access to a resource. Visual Basic (.NET) provides a SyncLock keyword like C#'s lock keyword. Java provides the keyword synchronized to lock code blocks, methods or objects [11] and libraries featuring concurrency-safe data structures.
But if the function is used in a reentrant interrupt handler and a second interrupt arises while the mutex is locked, the second routine will hang forever. As interrupt servicing can disable other interrupts, the whole system could suffer. The same function can be implemented to be both thread-safe and reentrant using the lock-free atomics in ...
Livelock is a special case of resource starvation; the general definition only states that a specific process is not progressing. [20] Livelock is a risk with some algorithms that detect and recover from deadlock. If more than one process takes action, the deadlock detection algorithm can be repeatedly triggered. This can be avoided by ensuring ...
For example, the above diagram shows a likely configuration for a two-stage watchdog timer. During normal operation the computer regularly kicks Stage1 to prevent a timeout. If the computer fails to kick Stage1 (e.g., due to a hardware fault or programming error), Stage1 will eventually timeout.
Java Database Connectivity (JDBC) is an application programming interface (API) for the Java programming language which defines how a client may access a database. It is a Java-based data access technology used for Java database connectivity. It is part of the Java Standard Edition platform, from Oracle Corporation.
The original form of the pattern, appearing in Pattern Languages of Program Design 3, [2] has data races, depending on the memory model in use, and it is hard to get right. Some consider it to be an anti-pattern. [3] There are valid forms of the pattern, including the use of the volatile keyword in Java and explicit memory barriers in C++. [4]
This is a list of the instructions that make up the Java bytecode, an abstract machine language that is ultimately executed by the Java virtual machine. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language.
