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

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.

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

pbuilder is a personal package builder for Debian packages.

• pbuilder constructs a chroot system, and builds a package inside the chroot. It is an ideal system to use to check that a package has correct build-dependencies. It uses apt extensively, and a local mirror, or a fast connection to a Debian mirror is ideal, but not necessary.

• pbuilder create uses debootstrap to create a chroot image.

• pbuilder update updates the image to the current state of testing/unstable/whatever.

• pbuilder build takes a *.dsc file and builds a binary in the chroot image.

• pdebuild is a wrapper for Debian Developers, to allow running pbuilder just like debuild, as a normal user.

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

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

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

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.

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.

Delta assists you in minimizing "interesting" files subject to a test of their interestingness. A common such situation is when attempting to isolate a small failure-inducing substring of a large input that causes your program to exhibit a bug.

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

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

Delve is a debugger for the Go programming language.

American fuzzy lop is a security-oriented fuzzer that employs a novel type of compile-time instrumentation and genetic algorithms to automatically discover clean, interesting test cases that trigger new internal states in the targeted binary. This substantially improves the functional coverage for the fuzzed code. The compact synthesized corpora produced by the tool are also useful for seeding other, more labor- or resource-intensive testing regimes down the road.

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.

GNU DDD, the Data Display Debugger, is a graphical front-end for command-line debuggers. Many back-end debuggers are supported, notably the GNU debugger, GDB. In addition to usual debugging features such as viewing the source files, DDD has additional graphical, interactive features to aid in debugging.

AFLplusplus is a security-oriented fuzzer that employs a novel type of compile-time instrumentation and genetic algorithms to automatically discover clean, interesting test cases that trigger new internal states in the targeted binary. This substantially improves the functional coverage for the fuzzed code. The compact synthesized corpora produced by the tool are also useful for seeding other, more labor- or resource-intensive testing regimes down the road. It is a fork of American Fuzzy Lop fuzzer and features:

• A more recent qemu version.

• More algorithms like collision-free coverage, enhanced laf-intel & redqueen, AFLfast++ power schedules, MOpt mutators, unicorn_mode, etc.

This package provides a frontend to GDB, the GNU debugger.

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.

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.

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.

rr is a lightweight tool for recording, replaying and debugging execution of applications (trees of processes and threads). Debugging extends GDB with very efficient reverse-execution, which in combination with standard GDB/x86 features like hardware data watchpoints, makes debugging much more fun.

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.
