by Aleksandra Uvarova

From the article:

New diagnostic rules. C, C++:

• V1116. Creating an exception object without an explanatory message may result in insufficient logging.
• V1117. The declared function type is cv-qualified. The behavior when using this type is undefined.
• V2022. Implicit type conversion from integer type to enum type.
• V5014. OWASP. Cryptographic function is deprecated. Its use can lead to security issues. Consider switching to an equivalent newer function.

HPX V1.10.0 released -- STE||AR Group

By Hartmut Kaiser | May 29, 2024 07:43 AM | Tags: performance parallelism heterogeneous computing distributed computing concurrency c++23 c++20 c++17 c++14 c++11

The STE||AR Group has released V1.10.0 of HPX -- A C++ Standard library for Concurrency and Parallelism.

HPX V1.10.0 Released

We have released HPX 1.10.0 — a major update to our C++ Standard Library for Concurrency and Parallelism. We have continued to modernize HPX to fully conform to the latest standardization efforts in the are of parallelism and concurrency. Our HPX documentation has seen a major overhaul for this release, please have a look here. We finished documenting the public local HPX API, we have added migration guides from widely used parallelization platforms to HPX (OpenMP, TBB, and MPI). Among other things, we have performed a lot of code cleanup and refactoring to improve the overall code quality and decrease compile times and to improve the consistency of our exposed APIs. The core implementation has seen many performance optimizations that impact every aspect of our applications.

If you have any questions, comments, or exploits to report you can reach us on IRC or Matrix (#ste||ar on libera.chat) or email us at hpx-users. We depend on your input!

You can download the release from our releases page or check out the v1.10.0 tag using git. A full list of changes can be found in the release notes.

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++20 Standard. As of this writing, HPX provides the only widely available open-source implementation of the new C++17, C++20, and C++23 parallel algorithms, including a full set of parallel range-based algorithms. Additionally, HPX implements functionalities proposed as part of the ongoing C++ standardization process, such as large parts of the features related parallelism and concurrency as specified by the upcoming C++23 Standard, the C++ Concurrency TS, Parallelism TS V2, data-parallel algorithms, executors, 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 that tends to improve the parallel efficiency of our applications and helps reducing complexities usually associated with parallelism and concurrency.

GCC 14 -fanalyzer improvements for buffer overflows and more -- David Malcolm

By Blog Staff | Apr 4, 2024 03:31 PM | Tags: None

For anyone interested in the top source of memory safety issues, out-of-bounds accesses... GCC 14 will be able to catch more cases, and even show them with some colorful retro ASCII art:

Improvements to static analysis in the GCC 14 compiler

by David Malcolm

It does require some source code annotation, but also delivers safety value in return.

From the article:

So for GCC 14, I've added the ability for the analyzer to emit text-based diagrams visualizing the spatial relationships in a predicted buffer overflow. ... [For example,] this diagram shows the destination buffer populated by the content from the strcpy call, and thus the existing terminating NUL byte used for the start of the strcat call. For non-ASCII strings ... it can show the UTF-8 representation of the characters ...

... [Another improvement] is that the analyzer now simulates APIs that scan a buffer expecting a null terminator byte, and will complain about code paths where a pointer to a buffer that isn't properly terminated is passed to such an API.

Plus more, such as:

The analyzer has a form of "taint analysis", which tracks attacker-controlled inputs, places where they are sanitized, and places where they are used without sanitization. In previous GCC releases this was too buggy to enable by default, with lots of false positives, so I hid it behind an extra command-line argument. I've fixed many bugs with this, so for GCC 14 I've enabled this by default when -fanalyzer is selected. This also enables these 6 taint-based warnings:

• -Wanalyzer-tainted-allocation-size
• -Wanalyzer-tainted-array-index
• -Wanalyzer-tainted-assertion
• -Wanalyzer-tainted-divisor
• -Wanalyzer-tainted-offset
• -Wanalyzer-tainted-size

Seastar, ScyllaDB, and C++23

By Jordi Mon Companys | Feb 17, 2024 05:36 AM | Tags: c++20 c++17

Seastar announces that now that C++23 is available, they will support C++23 and C++20 (dropping support for C++17) in accordance with their support policy

Seastar, ScyllaDB, and C++23

By Avi Kivity

From the article:

Seastar is an open-source (Apache 2.0 licensed) C++ framework for I/O intensive asynchronous computing, using the thread-per-core model. Seastar underpins several high- performance distributed systems: ScyllaDB, Redpanda, and Ceph Crimson. Seastar source is available on github. As a C++ framework, Seastar must choose which C++ versions to support. The support policy is last-two-versions. That means that at any given time, the most recently released version as well as the previous one are supported, but earlier versions cannot be expected to work. This policy gives users of the framework three years to upgrade to the next C++ edition while not constraining Seastar to ancient versions of the language.

Now that C++23 has been ratified, Seastar now officially supports C++20 and C++23. The previously supported C++17 is now no longer supported.
