Bugzilla

Bugzilla is a web-based general-purpose bug tracking system and testing tool originally developed and used by the Mozilla project, and licensed under the Mozilla Public License. Released as open-source software by Netscape Communications in 1998, it has been adopted by a variety of organizations for use as a bug tracking system for both free and open-source software and proprietary projects and products. Bugzilla is used, among others, by the Mozilla Foundation, WebKit, Linux kernel, FreeBSD, KDE, Apache, Eclipse and LibreOffice. Red Hat uses it, but is gradually migrating its product to use Jira. It is also self-hosting. Bugzilla was originally devised by Terry Weissman in 1998 for the nascent Mozilla.org project, as an open source application to replace the in-house system then in use at Netscape Communications for tracking defects in the Netscape Communicator suite. Bugzilla was originally written in Tcl, but Weissman decided to port it to Perl before its release as part of Netscape's early open-source code drops, in the hope that more people would be able to contribute to it, given that Perl seemed to be a more popular language at the time. Bugzilla 2.0 was the result of that port to Perl, and the first version was released to the public via anonymous CVS. In April 2000, Weissman handed over control of the Bugzilla project to Tara Hernandez. Under her leadership, some of the regular contributors were coerced into taking more responsibility, and Bugzilla development became more community-driven. In July 2001, facing distraction from her other responsibilities in Netscape, Hernandez handed control to Dave Miller, who was still in charge . Bugzilla 3.0 was released on May 10, 2007 and brought a refreshed UI, an XML-RPC interface, custom fields and resolutions, mod_perl support, shared saved searches, and improved UTF-8 support, along with other changes. Bugzilla 4.0 was released on February 15, 2011 and Bugzilla 5.0 was released in July 2015.
