Thread safe, MT-safe: Use a mutex for every single resource to guarantee the thread to be free of race conditions when those resources are accessed by multiple threads simultaneously. Thread safety guarantees usually also include design steps to prevent or limit the risk of different forms of deadlocks , as well as optimizations to maximize ...
In both cases, the features must be part of the language syntax and not an extension such as a library (libraries such as the posix-thread library implement a parallel execution model but lack the syntax and grammar required to be a programming language).
It is syntactically similar to C, but also has memory safety, garbage collection, structural typing, [7] and CSP-style concurrency. [14] It is often referred to as Golang to avoid ambiguity and because of its former domain name, golang.org, but its proper name is Go. [15] There are two major implementations:
ThreadSafe is a source code analysis tool that identifies application risks and security vulnerabilities associated with concurrency in Java code bases, using whole-program interprocedural analysis.
It is a mutable thread-safe implementation which ensures progress and supports lock-free, linearizable, O(1) snapshots. A data-structure similar to Ctries has been used in ScalaSTM, [7] a software transactional memory library for the JVM. The Scala standard library (as of 2.13.x) includes a Ctries implementation since February 2012. [8]
The issue thread opened on the subject was closed by a Google developer on 12 October 2010 with the custom status "Unfortunate" and with the following comment: "there are many computing products and services named Go. In the 11 months since our release, there has been minimal confusion of the two languages." [6]
The correspondence between the kind of property (safety vs liveness) with kind of proof (invariance vs well-foundedness) was a strong argument that the decomposition of properties into safety and liveness (as opposed to some other partitioning) was a useful one—knowing the type of property to be proved dictated the type of proof that is required.
Race condition in a logic circuit. Here, ∆t 1 and ∆t 2 represent the propagation delays of the logic elements. When the input value A changes from low to high, the circuit outputs a short spike of duration (∆t 1 + ∆t 2) − ∆t 2 = ∆t 1.
