Bash is the shell, or command-line interpreter, of the GNU system. It is compatible with the Bourne Shell, but it also integrates useful features from the Korn Shell and the C Shell and new improvements of its own. It allows command-line editing, unlimited command history, shell functions and aliases, and job control while still allowing most sh scripts to be run without modification.

Bats is a TAP-compliant testing framework for Bash. It provides a simple way to verify that the UNIX programs you write behave as expected. Bats is most useful when testing software written in Bash, but you can use it to test any UNIX program.

This package provides extensions that allow Bash to provide adapted completion for many common commands.

Bash TAP is a TAP-compliant Test::More-style testing library for Bash shell scripts and functions. Along with the Test::More-style testing helpers it provides helper functions for mocking commands and in-process output capturing.

This package provides XMLGraphics constants (originally from batik).

Batik is a Java-based toolkit for applications or applets that want to use images in the Scalable Vector Graphics (SVG) format for various purposes, such as display, generation or manipulation.

The Boehm-Demers-Weiser conservative garbage collector can be used as a garbage collecting replacement for C malloc or C++ new. It allows you to allocate memory basically as you normally would, without explicitly deallocating memory that is no longer useful. The collector automatically recycles memory when it determines that it can no longer be otherwise accessed.

The collector is also used by a number of programming language implementations that either use C as intermediate code, want to facilitate easier interoperation with C libraries, or just prefer the simple collector interface.

Alternatively, the garbage collector may be used as a leak detector for C or C++ programs, though that is not its primary goal.

This C library provides semi-portable access to hardware-provided atomic memory update operations on a number of architectures. These might allow you to write code that does more interesting things in signal handlers, write lock-free code, experiment with thread programming paradigms, etc.

fio is a tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user. The typical use of fio is to write a job file matching the I/O load one wants to simulate.

Microbenchmarks suite to evaluate MPI and PGAS (OpenSHMEM, UPC, and UPC++) libraries for CPUs and GPUs.

The time utility is a simple and often effective way of measuring how long a command takes to run (wall time). Unfortunately, running a command once can give misleading timings. multitime is, in essence, a simple extension to time which runs a command multiple times and prints the timing means, standard deviations, mins, medians, and maxes having done so. This can give a much better understanding of the command's performance.

Benchmark is a library to benchmark code snippets, similar to unit tests.

Locust is a performance testing tool that aims to be easy to use, scriptable and scalable. The test scenarios are described in plain Python. It provides a web-based user interface to visualize the results in real-time, but can also be run non-interactively. Locust is primarily geared toward testing HTTP-based applications or services, but it can be customized to test any system or protocol.

Note: Locust will complain if the available open file descriptors limit for the user is too low. To raise such limit on a Guix System, refer to info guix --index-search=pam-limits-service-type.

BenchExec is a framework for reliable benchmarking, which takes care of important low-level details for accurate, precise, and reproducible measurements. In particular, it makes use of cgroups, kernel namespaces, and overlay filesystems to restrict interference of the executed tool with the benchmarking host.

KDiskMark is an HDD and SSD benchmark tool. KDiskMark abstracts away the complexity of the Flexible I/O Tester (fio) command via a convenient graphical user interface (GUI) and handles its output to provide an easy to view and interpret benchmark result. The application is written in C++ with Qt and doesn't have any runtime KDE dependencies. Among its features are:

• Configurable block size, queues, and threads count for each test

• Many languages support

• Report generation.
