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.
The project's maintainer can then scan through the list of patches, marking each with a certain state, such as Accepted, Rejected or Under Review. Old patches can be sent to the archive or deleted. Currently, Patchwork is being used for a number of open-source projects, mostly subsystems of the Linux kernel and FFmpeg. Although Patchwork has ...
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.
kpatch is a feature of the Linux kernel that implements live patching of a running kernel, which allows kernel patches to be applied while the kernel is still running. By avoiding the need for rebooting the system with a new kernel that contains the desired patches, kpatch aims to maximize the system uptime and availability.
This makes the script more portable, but also increases the risk that the wrong interpreter is selected because it searches for a match in every directory on the executable search path. It also suffers from the same problem in that the path to the env binary may also be different on a per-machine basis.
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 ...
YUM is implemented as libraries in the Python programming language, with a small set of programs that provide a command-line interface. [7] GUI-based wrappers such as YUM Extender (yumex) also exist, [8] and has been adopted for Fedora Linux until version 22. [9]
