|Stable release||4.1 / March 6, 2005|
|Type||Bug tracking system|
GNATS is a set of tools for tracking bugs reported by users to a central site. It allows problem report management and communication with users via various means. GNATS stores all the information about problem reports in its databases and provides tools for querying, editing, and maintenance of the databases.
GNATS is used by GNU packages, FreeBSD, NetBSD and OpenBSD. The Apache Software Foundation used the software from 1996-2002, and the Mutt project until 2006. It is also used, or was used in the past, by Nordic Optical Telescope, CERN, Green Bank Telescope, NRAO AIPS++, European Software Institute, and the BaBar Project at SLAC.
In early June 2014, FreeBSD announced concrete plans to migrate from GNATS to Bugzilla, claiming that Bugzilla supports finer granularity for categories and keywords. Furthermore, the announcement states that GNATS is missing many features that people expect from a modern bug tracker.
GNATS had its first stable release in 1992. Initially, its only interface was via email but multiple web and graphical interfaces were later added. During the 1990s, part of the development was performed by Cygnus Solutions, with other features contributed by users.
Although GNATS is still in use, no official releases have been made and there have been no notable features added to the main repository since the 4.1 release in 2005. Some changes have been made in the developers' source code repository, and a 4.2 release was discussed in 2012 but no official release was made.
Built as a client-server architecture, GNATS works with many interfaces (described below) including email, command line, and web interfaces. All GNATS databases and configuration can be stored in plain text files, which helps in the modularity of GNATS. Categorisation and recategorisation of bug reports is particularly simple.
Four interfaces exist for GNATS:
- A Web interface to query and open tickets, with GNATS running as a background process (a "daemon")
- Emacs GNATS mode
- An extension (a "major mode") for GNU Emacs and XEmacs allowing direct access to GNAT issue-trackers
- A html and mail interface, used by the FreeBSD and NetBSD projects
- A cross-platform application, written in the Tcl/Tk language

- "Announcement of Migration from GNATS to Bugzilla on the FreeBSD mailing list". "Bugzilla supports finer granularity for categories and keywords and over time we will adopt more of these, making it easier to filter bugs into specific target areas. It is now easy for multiple people to track a single bug, without having to have them assigned to custom mailing lists, add attachments to bugs, and so on. Many features that people expect from a modern bug tracker are simply not present in GNATS."
- "Perl-based Bug Tracking". "The GNATS/PRMS Gnu Bug Tracking System has been the cornerstone of Free Software bug tracking systems. The core is command-line, e-mail based, allowing additional tools and GUI wrappers to be created for it. These include wwwgnats, a web interface, and TkGnats, a Tk interface."
