28.Dt DEVELOPMENT 7
29.Os
30.Sh NAME
31.Nm development
32.Nd introduction to
33.Fx
34development process
35.Sh DESCRIPTION
36.Fx
37development is split into three major suprojects: doc, ports, and src.
38Doc is the documentation, such as the
39.Fx
40Handbook.
41To read more, see:
42.Pp
43.Lk https://www.FreeBSD.org/doc/en/books/fdp-primer/
44.Pp
45Ports, described further in
46.Xr ports 7 ,
47are the way to build, package, and install third party software.
48To read more, see:
49.Pp
50.Lk https://www.FreeBSD.org/doc/en/books/porters-handbook/
51.Pp
52The last one, src, revolves around the source code for the base system,
53consisting of the kernel, and the libraries and utilities commonly called
54the world.
55.Pp
56The Committer's Guide, describing topics relevant to all committers,
57can be found at:
58.Pp
59.Lk https://www.FreeBSD.org/doc/en/articles/committers-guide/
60.Pp
61.Fx
62src development takes place in the CURRENT branch in Subversion,
63located at:
64.Pp
65.Lk https://svn.FreeBSD.org/base/head
66.Pp
67There is also a read-only GitHub mirror at:
68.Pp
69.Lk https://github.com/freebsd/freebsd
70.Pp
71Changes are first committed to CURRENT and then usually merged back
72to STABLE.
73Every few years the CURRENT branch is renamed to STABLE, and a new
74CURRENT is branched, with an incremented major version number.
75Releases are then branched off STABLE and numbered with consecutive minor
76numbers.
77.Pp
78Layout of the source tree is described in
79.Xr hier 7 .
80Build instructions can be found in
81.Xr build 7
82and
83.Xr release 7 .
84Kernel programming interfaces (KPIs) are documented in section 9
85manual pages; use
86.Ql "apropos -s 9 ''"
87for a list.
88Regression test suite is described in
89.Xr tests 7 .
90For coding conventions, see
91.Xr style 9 .
92.Pp
93To ask questions regarding development, use the mailing lists,
94such as freebsd-arch@ and freebsd-hackers@:
95.Pp
96.Lk https://lists.FreeBSD.org/
97.Pp
98To get your patches integrated into the main
99.Fx
100repository use Phabricator;
101it is a code review tool that allows other developers to review the changes,
102suggest improvements, and, eventually, allows them to pick up the change and
103commit it:
104.Pp
105.Lk https://reviews.FreeBSD.org/
106.Sh EXAMPLES
107Check out the CURRENT branch, build it, and install, overwriting the current
108system:
109.Bd -literal -offset indent
110svnlite co https://svn.FreeBSD.org/base/head src
111cd src
112make -j8 buildworld buildkernel installkernel
113reboot
114.Ed
115.Pp
116After reboot:
117.Bd -literal -offset indent
118cd src
119make -j8 installworld
120reboot

130.Sh HISTORY
131The
132.Nm
133manual page was originally written by
134.An Matthew Dillon Aq Mt dillon@FreeBSD.org
135and first appeared
136in
137.Fx 5.0 ,
138December 2002.
139It was since extensively modified by
140.An Eitan Adler Aq Mt eadler@FreeBSD.org
141to reflect the repository conversion from
142.Xr cvs 1
143to
144.Xr svn 1 .
145It was rewritten from scratch by
146.An Edward Tomasz Napierala Aq Mt trasz@FreeBSD.org
147for
148.Fx 12.0 .
