1The FoxtrotGPS project uses Bazaar for version control. Here are a few
2basic instructions to help you get started with using it.

5Contributing Changes

8Overview of the steps:
9
101. Log in (you only have to do this once on a computer).
112. Create a branch.
123. Edit files, fix your bug or add your change.
134. Commit the files that changed (which only affects your computer).
145. Send the changes to the maintainer, there are several ways to do this.
156. The maintainer(s) will evaluate your change and if they are acceptable,
16   merge them into the trunk in a timely fashion.
177. Update your source code from the trunk

211. Log in, using your own email address.

262. Create a branch
27------------------
28
29This is almost the same as the first step to building from source.
30You should check out code to your own branch. If you are fixing a bug,
31name the branch after the bug. This makes it easier to tell
32your branch from the trunk when you submit patches.
33
34This is how you might create a branch to fix bug 663102:
35
36    bzr branch https://www.foxtrotgps.org/branches/foxtrotgps-dev/ foxtrotgps-663102
37    cd foxtrotgps-663102
38
39If you are working on a new feature instead of a simple bug fix you might
40name the branch after the feature, for example "foxtrotgps-usng-support".
41
423. Make your change (or addition or whatever)
43---------------------------------------------
44
45"One change" means you want to do the minimum necessary to fix just
46one bug, not several bugs. This makes evaluating the work you did
47easier for the maintainers, and therefore decreases the turn around
48time on your changes being incorporated (and increases the probability
49that your changes will be accepted!)
50
51It goes without saying, compile and test thoroughly before sending changes in.
52
53If you add a new file to the project use the "add" command:
54
55    bzr add newfilename
56
574. Commit your change
58---------------------
59
60Now that you have updated one or more files, you need to commit the
61changes. From your source directory, execute the commit command along
62with a brief but meaningful message. For example:
63
64    bzr commit -m "These changes fix bug number 663102"
65
66NOTE that unlike other version control systems (such as subversion),
67when you perform a commit with Bazaar the changes stay on your own
68machine. The changes are NOT sent to the remote repository until you
69execute a "push" command. Thus you can do many commits and/or reverts
70before you share the changes. This makes sense, because if you are
71adding a new feature, you have all the benefits of version control
72without having to publish any non-working code. It also means you can
73work disconnected from a network, pushing changes when you reconnect.
74
755. Send your changes to the maintainer
76--------------------------------------
77
78If the change is relatively small, you can "send" the changes to a
79patch file and then attach the file to the bug in the comments section
80of the bug tracking system.
81
82The bug tracker is here: https://bugs.launchpad.net/foxtrotgps/
83
84The send-to-a-file command looks like this:
85
86    bzr send -o ../fix663102.patch
87
88Now you can use a web browser to connect to the bug tracker and add a
89comment to bug 663102, attaching the file fix663102.patch.
90
91If you are working on a big change and you have access to your own
92publicly accessible SFTP/Web site, you can use SFTP mode to upload
93your changes to your own site, and then share the Web URL with other
94developers either by email or through the bug tracker.
95
966. Wait
97-------
98
99After letting us know about your changes, the next step is to wait
100for the changes to be accepted and merged into the trunk.
101
1027. Repeat!
103----------
104
105To work on a NEW bug or feature, you'd start the whole cycle again,
106checking out a new copy of the code so that you are starting from the
107trunk.
108
109Publishing with SFTP
110====================
111
112To publish code, you need a server that is accessible over the
113Internet. Many cheap hosting services (hostmonster.com is one) include
114ssh and sftp access. If you have an account at one of these providers,
115then all you need do is place a bzr repository on the server in a
116space that is accessible by both sftp and http. Then you can directly
117publish code with bzr commands, and give the repository http URL to
118friends.
119
120If you run a public Web server, and it has the openssh server package
121installed, all you need to do is edit its configuration file to enable
122sftp access.
123
124More details of setting up an sftp server are really beyond the scope
125of this little document. Please don't let access to an sftp server
126stop you from participating; let us know and we'll work something out.
127
128Sample SFTP Publish Commands
129============================
130
131If you have a domain called example.com the publish command would be
132similar to this:
133
134    bzr push --create-prefix sftp://jdoe@example.com/~/public_html/branches/foxtrotgps
135
136Bazaar will create the foxtrotgps directory on the remote server and
137upload your branch to it.
138
139This example would make your repository accessible to others using
140Bazaar with a command like this:
141
142    bzr branch https://www.example.com/branches/foxtrotgps
