Happy Birthday to Fossil and congratulations to Richard!

The seventh anniversary of the first self-commit of Fossil source code
was this past Monday. Time flies.
The logical predecessor of Fossil was CVSTrac
(http://www.cvstrac.org/) which was a wiki and trouble-ticket system
built atop CVS. CVSTrac became the inspiration for Trac
(http://trac.edgewall.org/wiki/CvsTrac) which is a similar tool for
SVN that became far more popular than CVSTrac and which is still in
active use. Fossil was originally created to provide features needed
in SQLite development, features that I couldn't get with CVS+CVSTrac,
or with Monotone or Git or Mercurial or any other configuration
management system available at the time. I worked on prototypes of
Fossil for a year or more prior to the first self-commit on
2007-07-21, but none of those early prototypes survive.
Code archeologists will be able to find a lot of commonality between
the CVSTrac and Fossil source codes. There is a clear genetic
relationship between the two systems.
Fossil was created for the purpose of aiding in the development of
SQLite. (Other uses for Fossil, though welcomed, are secondary.) The
SQLite documentation sources
(http://www.sqlite.org/docsrc/timeline?a=2000-01-01) were split off
from the SQLite source tree in CVS on 2007-11-12, just a few months
after Fossil began self-hosting. But the core SQLite source code did
not move to Fossil until 2009-08-11, just after the release of SQLite
version 3.6.17, over two years after Fossil became self-hosting. The
move from CVS to Fossil has proven to be a boon for SQLite development.
CVSTrac was in active use by SQLite for a little over 7 years. To my
knowledge, nobody uses CVSTrac any more. (OpenSSL was the last known
user of CVSTrac and they switched over to Git at the beginning of
2013.) Fossil will soon overtake CVSTrac in terms of years of use, and
Fossil has a great deal more momentum and a much larger user base than
CVSTrac ever had.
