PVS-Studio 6.16 released

By Andrey Karpov | Jun 28, 2017 01:16 AM | Tags: tools static code analyzer errors devops

PVS-Studio is a static code analyzer that detects errors and potential vulnerabilities in the source code of programs written in C/C++/C#. Version 6.16 has obtained 11 new general analysis diagnostics.

PVS-Studio 6.16 released

by Andrey Karpov

About the release:

In a sense, this is a milestone for us. The thing is that we cannot add more numbers of general analysis warnings, otherwise they will concur with the numbers of micro-optimization diagnostics. It seemed to us that the list of 300 diagnostics was endless, but now it is over and we got to the point of 800, where we have micro-optimization diagnostics. In the next release we plan to resume numbering the general-analysis warnings with V1000. Download and enjoy the new version of PVS-Studio now by clicking here.

There Is A New Future -- Felix Petriconi

Version 1.0 of a new C++ future and channel library has been released.

There Is A New Future

by Sean Parent, Foster Brereton and Felix Petriconi

About the library:

This library provides high level abstractions for implementing algorithms that eases the use of multiple CPU cores while minimizing the contention.

The future implementaton differs in several aspects compared to the C++11/14/17 standard futures: It provides continuations and joins, which were just added in a C++17 TS. But more important this futures propagate values through the graph and not futures. This allows an easy way of creating splits. That means a single future can have multiple continuations into different directions. An other important difference is that the futures support cancellation. So if one is not anymore interested in the result of a future, then one can destroy the future without the need to wait until the future is fullfilled, as it is the case with std::future (and boost::future). An already started future will run until its end, but will not trigger any continuation. So in all these cases, all chained continuations will never be triggered. Additionally the future interface is designed in a way, that one can use build in or custom build executors.

Since one can create with futures only graphs for single use, this library provides as well channels. With these channels one can build graphs, that can be used for multiple invocations.

Interesting library

corsl - Coroutine support library

by Alexander Bessonov

From the article:

corsl stands for "Coroutine Support Library" and consists of a number of utility classes and functions that simplify asynchronous programming in Windows. It is inspired by an amazing cppwinrt library, developed by Microsoft.

cppwinrt was created as a language projection for Windows Runtime, which is supported by Windows 8 or later operating systems. It is impossible to use in prior Windows versions.

One of the goals of corsl library was being able to use it under Windows Vista or later operating system...

The fastest feature-rich C++98/C++11 single-header testing framework for unit tests and TDD

doctest 1.2 released! Focus on features and runtime performance

by Viktor Kirilov

From the release:

• improved runtime by more than 30 times compared to version 1.1.4
• templated test cases - parameterized by type
• an exception translation mechanism
• logging context with lazy stringification
• multiple binaries (dll/exe) can share the same test runner/registry
• subcases can be filtered
• the TEST_SUITE() macro now works with blocks of code
• crash handling support - using signals under UNIX and SEH under Windows
• added test case decorators - skip, may_fail, should_fail, expected_failures, timeout, etc.
• can show duration of test case execution
• added support for un-parenthesized expressions containing commas in asserts - CHECK(std::vector<int>{1, 2} == std::vector<int>{1, 3});
• and many more! see the complete changelog
