36.Dt COMMITTER 7
37.Os
38.Sh NAME
39.Nm committer
40.Nd rules for DragonFly committers
41.Sh GIT REPOSITORY ON YOUR LOCAL MACHINE
42See
43.Xr development 7
44how to obtain a fresh copy of the
45.Dx
46git repository on your machine.
47Note that all developers have to pull/push through
48.Xr ssh 1 .
49Your
50.Pa ~/.gitconfig
51should contain at least:
52.Bd -literal -offset indent
53[user]
54	name = Your Name
55	email = <login>@dragonflybsd.org
56.Ed
57.Pp
58Alternatively, see the
59.Va user.name
60and
61.Va user.email
62variables in
63.Xr git-config 1 .
64.Sh SSH DSA KEYS
65The git repository machine is
66.Pa crater.dragonflybsd.org ,
67and the
68.Dx
69developer machine is
70.Pa leaf.dragonflybsd.org .
71We create
72an account for you on both machines and install your public SSH
73key to give you access.
74.Pp
75Your
76.Pa crater
77account is set up for git repository only.
78It can only operate as a git slave and cannot be logged into.
79That is,
80.Pa crater.dragonflybsd.org
81is only used as part of
82.Nm git Cm push
83operations.
84.Pp
85Your
86.Pa leaf
87account is a general developer account.
88Any
89.Dx
90developer can have a
91.Pa leaf
92account, whether a committer or not.
93It can be useful as a developer rendezvous,
94however.
95For example, people upload kernel cores to
96.Pa leaf
97so other
98developers can look at them.
99You log into your
100.Pa leaf
101account with:
102.Bd -literal -offset indent
103ssh you@leaf.dragonflybsd.org
104.Ed
105.Pp
106The rules for account use are in
107.Pa leaf Ap s
108MOTD.
109It is very important that you never install a password or create a SSH
110key pair on
111.Pa leaf
112to use to access other machines.
113Because non-committers can have
114.Pa leaf
115accounts,
116.Pa leaf
117is not considered a secure machine.
118.Sh TESTING COMMIT ACCESS
119There is a directory called
120.Pa /usr/src/test/test .
121To test your commit
122access, try making a modification and committing a file in this
123directory.
124Try to push the commit to
125.Pa crater
126afterwards.
127.Bd -literal -offset indent
128cd /usr/src/test/test
129(edit something)
130git commit file_you_edited
131git push crater
132.Ed
133.Sh COMMITTING REAL WORK
134Make modifications as needed.
135For example, edit files.
136If adding new files make git aware of them like this.
137Files and directories can just be added locally.
138These operations do not actually affect the master repository.
139Instead they are stored in your local copy of the repository and then
140synchronized to the repository when you
141.Nm git Cm push .
142.Bd -literal -offset indent
143git add filename
144git commit filename
145.Ed
146.Pp
147To actually push your changes to the the repository on
148.Pa crater ,
149use:
150.Bd -literal -offset indent
151git push crater
152.Ed
153.Pp
154See
155.Xr development 7
156how to commit to a specific branch (to merge bug fixes, for example).
157.Pp
158Do not set the default remote tag to
159.Pa origin .
160It is set to
161.Pa crater
162by default.
163This reduces instances where accidental commits or repository
164operations are made on the master repository.
165.Sh STRUCTURE OF COMMIT MESSAGES
166As many
167.Xr git 1
168tools display the first line of a commit message as a summary,
169structure your commit messages like this, if possible:
170.Bd -literal -offset indent
171One line summary of your change.
172
173Maybe more text here describing your changes in detail (including
174issue tracker id's etc).
175.Ed
176.Sh DISCUSSING COMMITTABLE WORK BEFOREHAND
177Discussion prior to committing usually occurs on the
178.Pa kernel@ ,
179.Pa submit@ ,
180or
181.Pa bugs@
182mailing lists and depends on the work involved.
183Simple and obvious work such as documentation edits or additions,
184doesn't really need a heads up.
185.Pp
186Simple and obvious bug fixes don't need a heads up either, other than to
187say that you will (or just have) committed the fix, so you don't
188race other committers trying to do the same thing.
189Usually the developer most active in a discussion about a bug commits the
190fix, but it isn't considered a big deal.
191.Pp
192More complex issues are usually discussed on the lists first.
193Non-trivial but straight forward bug fixes usually go through
194a testing period, where you say something like:
195.Do
196Here is a patch
197to driver BLAH that fixes A, B, and C, please test it.
198If there are no objections I will commit it next Tuesday.
199.Dc
200(usually a week,
201or more depending on the complexity of the patch).
202.Pp
203New drivers or utilities are usually discussed.
204Committers will often commit new work
205.Em without
206hooking it into the buildworld or
207buildkernel infrastructure in order to be able to continue
208development on it in piecemeal without having to worry about it
209breaking buildworld or buildkernel, and then they hook it in as a
210last step after they've stabilized it.
211Examples of this include
212new versions of GCC, updates to vendor packages such as bind,
213sendmail, etc.
214.Sh SOURCE OWNERSHIP
215Areas within the repository do not
216.Dq belong
217to any committer.
218Often situations will arise where one developer commits work and
219another developer finds an issue with it that needs to be corrected.
220.Pp
221All committed work becomes community property.
222No developer has a
223.Dq lock
224on any part of the source tree.
225However, if a developer is
226actively working on a portion of the source tree and you find a bug
227or other issue, courtesy dictates that you post to
228.Pa kernel@
229and/or email the developer.
230.Pp
231This means that, generally, if you do not see a commit to an area
232of the source tree in the last few weeks, it isn't considered active and
233you don't really need to confer with the developer that made the
234commit, though you should still post to the
235.Pa kernel@
236mailing list and, of course, confer with developers when their expertise
237is needed.
238.Pp
239One exception to this rule is documentation.
240If any developer commits
241new work, the documentation guys have free reign to go in and correct
242.Xr mdoc 7
243errors.
244This is really a convenience as most developers are not
245.Xr mdoc 7
246gurus and it's a waste of time for the doc guys to post to
247.Pa kernel@
248for all the little corrections they make.
249.Sh CONFLICTS
250On the occasion that a major code conflict occurs, for example if two
251people are doing major work in the same area of the source tree and forgot
252to collaborate with each other, the project leader will be responsible for
253resolving the conflict.
254Again, the repository is considered community
255property and it must be acceptable for any developer to be able to work on
256any area of the tree that he or she has an interest in.
257.Sh MAJOR ARCHITECTURAL CHANGES
258This is generally
259.An Matt Dillon Ap s
260area of expertise.
261All major architectural changes must be discussed on the
262.Pa kernel@
263mailing list and he retains veto power.
264.Pp
265This isn't usually an issue with any work.
266At best if something
267doesn't look right architecturally he'll chip in with adjustments to
268make it fit in.
269Nothing ever really gets vetoed.
