Coccinelle was initially used to aid the evolution of the Linux kernel, providing support for changes to library application programming interfaces (APIs) such as renaming a function, adding a function argument whose value is somehow context-dependent, and reorganizing a data structure.
In doing so, Quilt makes it easier for many programmers to test and evaluate the different changes amongst patches before they are permanently applied to the source code. Tools of this type are very important for distributed software development , in which many programmers collaborate to test and build a single large codebase.
Salt (sometimes referred to as SaltStack) is a Python-based, open-source software for event-driven IT automation, remote task execution, and configuration management. Supporting the " infrastructure as code " approach to data center system and network deployment and management, configuration automation, SecOps orchestration, vulnerability ...
In a 2019 paper considering Linux open-source patching tools, Spacewalk was commended for having a software inventory and community support but limited support for distributions; notably, Ubuntu was an issue. [58]
KernelCare is a live kernel patching service that provides security patches and bugfixes for a range of popular Linux kernels [2] that can be installed without rebooting the system. [3] KernelCare software is a commercial product. The first beta was introduced in March 2014 and it was commercially launched in May 2014.
Ksplice is an open-source [2] [3] extension of the Linux kernel that allows security patches to be applied to a running kernel without the need for reboots, avoiding downtimes and improving availability (a technique broadly referred to as dynamic software updating). Ksplice supports only the patches that do not make significant semantic changes ...
In computing, copy-and-patch compilation is a simple compiler technique intended for just-in-time compilation (JIT compilation) that uses pattern matching to match pre-generated templates to parts of an abstract syntax tree (AST) or bytecode stream, and emit corresponding pre-written machine code fragments that are then patched to insert memory addresses, register addresses, constants and ...
Jinja, a Python-powered template engine, inspired by Django's template engine; Kid, simple template engine for XML-based vocabularies; Meson build system, a software tool for automating the building (compiling) of software; mod_python, an Apache module allowing direct integration of Python scripts with the Apache web server
