Continuous integration with Travis CI

by Richel Bilderbeek

From the article:

In today’s guest post, Richel Bilderbeek gives us some insight about some the many possible advantages of setting up a continuous integration service, showing some minimal complete examples. Richel works as a PhD in Theoretical Biology at the University of Groningen industry, in his free time teaching people from ages 7-77 about C++, Processing, Arduino and R. Falling inexplicably in love with a C++ code snippet of Doom as a kid, he started using C++ only since 2001, and you can reach him through his website...

HPX version 1.0 released -- STE||AR Group

By Hartmut Kaiser | Apr 24, 2017 06:01 AM | Tags: performance parallelism heterogeneous computing distributed computing c++17 c++14 c++11

The STE||AR Group has released V1.0 of HPX -- A C++ Standard library for parallelism and concurrency.

HPX V1.0 Released

The newest version of HPX (V1.0) is now available for download! Please see here for the release notes.

HPX exposes an API fully conforming to the concurrency related parts of the C++11/C++14/C++17 standards, extended and applied to distributed and heterogeneous computing, and aligned with the ongoing standardization discussions.

From the announcement:

• HPX is a general purpose parallel C++ runtime system for applications of any scale. It implements all of the related facilities as defined by the C++ Standard. As of this writing, HPX provides the only widely available open-source implementation of the new C++17 parallel algorithms. Additionally, HPX implements functionalities proposed as part of the ongoing C++ standardization process, such as large parts of the C++ Concurrency TS, task blocks, data-parallel algorithms, executors, index-based parallel for loops, and many more. It also extends the existing C++ Standard APIs to the distributed case (e.g. compute clusters) and for heterogeneous systems (e.g. GPUs).
• HPX seamlessly enables a new asynchronous C++ Standard Programming Model which tends to improve the parallel efficiency of our applications and helps reduce complexities usually associated with concurrency

The new boost is out!

Boost 1.64.0 is released

From the article:

New Libraries

Process:
Process library by Klemens D. Morgenstern, that provides cross platorm ways to allows you to:

• create child processes
• setup streams for child processes
• communicate with child processes through streams (synchronously or asynchronously)
• wait for processes to exit (synchronously or asynchronously)
• terminate processes

Broken feature:

GitHub #67: "group.wait() does not return".

Updated Libraries

Any:

• Suppressed false warnings about returning reference to temporary
• boost::addressof is now used instead of directly taking the address #12615
• Headers are not included using double quotes any more #12053
• CI tests now run with address, leak, and undefined sanitizers
• Added more test

Atomic:

• Fixed possible incorrect code generation in 64-bit atomic operations on 32-bit x86 with gcc versions older than 4.7 and compatible compilers.

Config:

• Added BOOST_NO_CXX11_SFINAE_EXPR defect detection.

Welcome CLion 2017.1, new version of the cross-platform C/C++ IDE from JetBrains!

CLion 2017.1 released

by Anastasia Kazakova

From the article:

With the 2017.1 update CLion has learned a lot about C++14 and C++17. It improves your debugging experience with a disassembly view and unit testing with support for the Catch framework. In addition, Windows users are welcome to check out the new experimental support for Microsoft Visual C++ compiler.

The highlighted new features are:

• Extended support for C++14 (in brief, all except constexpr are there!)
• First step towards C++17 support (nested namespaces!)
• First step to modernizing your C++ code: make auto intention
• Support for precompiled headers and headers included via -include compile option
• Disassembly view in debugger (GDB)
• Support for the Catch unit test framework
• Experimental support for Microsoft Visual C++ compiler
• Find in Path in popup
• Enhanced Log viewer and branches popup
• Swift plugin: SourceKit inspections and ability to generate type from usage

CppDepend v2017 Released! -- CoderGears

By James | Mar 28, 2017 11:40 PM | Tags: None

We are happy to inform you that CppDepend v2017 has been released and is now available for download! CppDepend v2017 allows architects and developers to analyze C and C++ code base, automate code reviews, and facilitate refactoring and migration.

About the release

With CppDepend v2017 Save time, reduce costs and deliver high-quality code with these important updates:

• Support: for Visual Studio 2017 RC.
• Smart Technical Debt Estimation: CppDepend v2017 is the only VS extension that can tell the developer that, for example, since this morning the code just written has introduced debt that would cost about 30 minutes should it have to be repaid later. Knowing this, the developer can fix the code before even committing it to the source control.
• Quality Gate: A Quality Gate is a check on a code quality fact that must be enforced before releasing and eventually, before committing to source control. Quality Gates for example can forbid issues with a certain severity introduced since the baseline, enforce particular code coverage by tests ratio on new and refactored code or enforce thresholds on any Technical Debt criteria.
• Default Rules Set Improvements: All default rules have been revisited to smartly estimate the cost-to-fix and the severity of each issue and also to filter more false positives.
• Dashboard Improvements: The dashboard now includes Technical Debt metrics, Quality Gates status and Issues facts. It allows drilling down any Technical Debt fact and filter issues through any criteria (new, severity, cost to fix...).
• Enhanced Baseline Experience: Do you want to measure progress since this morning, last week or since the last release? Choose the baseline in a single click from the Dashboard and harness the updated results in just a few seconds.
• Report Improvements: The CppDepend report now includes the new Dashboard and proposes Technical Debt and Quality Gates highlights.
• Code Query Improvements: CppDepend Code Query LINQ (CQLinq) can now be used to live query the Technical Debt and the issues-set. Also, CQLinq now lets users write custom Quality Gates. With CQLinq, smart Technical Debt estimations are computed through custom formulas written in C#. Finally, a code query can now match code elements of various kinds (assemblies, namespace,s types, methods, fields) to obtain more informative results.

PVS-Studio: searching software weaknesses

By Andrey Karpov | Mar 16, 2017 06:44 AM | Tags: vulnerabilities security pvs-studio cwe common weakness enumeration bugs

As we check Apache HTTP Server, we see bugs crawling everywhere across the code. But wait! These are not just bugs, but security weaknesses!

PVS-Studio: searching software weaknesses

by Andrey Karpov, Phillip Khandeliants

From the article:

PVS-Studio has always been able to detect a large number of various security defects (potential vulnerabilities) in the program code. However, historically, we positioned PVS-Studio as a tool to search for errors. We see a trend in the software development to look for vulnerabilities in the code, although it is just the same. It seems to us that it is high time to do the rebranding of our static analyzer PVS-Studio. We will start with Common Weakness Enumeration (CWE). This article provides a table that shows matches of PVS-Studio diagnostic warnings of with the classifier. The table will be gradually updated and changed, but we can already use the table to write articles about security defects detected in projects. We suppose it would attract more attention of the software security specialists.
