The Ubuntu project digitally signs its Release files. This package contains the archive keys used for that.

apt-mirror is a small tool that provides the ability to selectively mirror APT sources, including GNU/Linux distributions such as Debian and Trisquel.

The Kali distribution signs its packages. This package contains the archive keys used for that.

This package provides the low-level infrastructure for handling the installation and removal of Debian software packages.

Debootstrap is used to create a Debian base system from scratch, without requiring the availability of dpkg or apt. It does this by downloading .deb files from a mirror site, and carefully unpacking them into a directory which can eventually be chrooted into.

Reprepro is a tool to manage a repository of Debian packages (.deb, .udeb, .dsc, ...). It stores files either being injected manually or downloaded from some other repository (partially) mirrored into one pool/ hierarchy. Managed packages and files are stored in a Berkeley DB, so no database server is needed. Checking signatures of mirrored repositories and creating signatures of the generated Package indices is supported.

This package mainly meant for caching packages of Debian or Debian based distributions (like Trisquel) through HTTP. It also has partial support for HTTPS and other distributions / repositories (OpenSUSE, Arch Linux, Sourceforge mirror network, Cygwin mirrors) as this requires more configuration and comes with some limitations. Packages can be imported manually either by copying files from another apt-cacher-ng instance or by importing them from CD, DVD, jigdo, etc. While apt-cacher-ng can work offline, it requires some online access before that to build valid index files. It also supports partial mirroring. It can be configured through configuration files and/or a web interface and/or a command line tool.

The Debian project digitally signs its Release files. This package contains the archive keys used for that.

The Pureos distribution signs its packages. This package contains the archive keys used for that.

The Trisquel distribution signs its packages. This package contains the archive keys used for that.

The Debian ports-archive digitally signs its Release files. This package contains the archive keys used for that.

Fandango is a generator of inputs and interactions for software testing. Given the specification of a program's input or interaction language, Fandango generates myriads of valid sample inputs for testing. The specification language combines a grammar with constraints written in Python. Minimization or maximization soft constraints and input distributions can also be expressed in Fandango.

Fiu provides CLI utilities and a C library to mark points of failure inside your code and to enable/disable the failure of those points.

C-Reduce is a tool that takes a large C or C++ program that has a property of interest (such as triggering a compiler bug) and automatically produces a much smaller C/C++ program that has the same property. It is intended for use by people who discover and report bugs in compilers and other tools that process C/C++ code.

Scanmem is a debugging utility designed to isolate the address of an arbitrary variable in an executing process. Scanmem simply needs to be told the pid of the process and the value of the variable at several different times. After several scans of the process, scanmem isolates the position of the variable and allows you to modify its value.

C-Vise is a Python port of the C-Reduce tool that is fully compatible and uses the same efficient LLVM-based C/C++ clang_delta reduction tool.

cppdap is a C++11 library ("SDK") implementation of the Debug Adapter Protocol, providing an API for implementing a DAP client or server. cppdap provides C++ type-safe structures for the full DAP specification, and provides a simple way to add custom protocol messages.

Remake is an enhanced version of GNU Make that adds improved error reporting, better tracing, profiling, and a debugger.

MspDebug supports FET430UIF, eZ430, RF2500 and Olimex MSP430-JTAG-TINY programmers, as well as many other compatible devices. It can be used as a proxy for gdb or as an independent debugger with support for programming, disassembly and reverse engineering.

The libbacktrace library can be linked into a C/C++ program to produce symbolic backtraces.

Stress Make is a customized GNU Make that explicitly manages the order in which concurrent jobs are run to provoke erroneous behavior into becoming manifest. It can run jobs in the order in which they're launched, in backwards order, or in random order. The thought is that if code builds correctly with Stress Make, then it is likely that the Makefile contains no race conditions.

Zzuf is a transparent application input fuzzer. It works by intercepting file operations and changing random bits in the program's input. Zzuf's behaviour is deterministic, making it easy to reproduce bugs.

The libleak tool detects memory leaks by hooking memory functions such as malloc. It comes as a shared object to be pre-loaded via LD_PRELOAD when launching the application. It prints the full call stack at suspicious memory leak points. Modifying or recompiling the target program is not required, and the detection can be enabled or disabled while the target application is running. The overhead incurred by libleak is smaller than that of other tools such as Valgrind, and it aims to be easier to use than similar tools like mtrace.

This is a Linux kernel module that implements workarounds needed for using the rr debugger with AMD Zen CPU.
