1 Checklist (and a short version for the impatient) |
|
2 ================================================= |
|
3 |
|
4 * Commits: |
|
5 |
|
6 - Make commits of logical units. |
|
7 |
|
8 - Check for unnecessary whitespace with "git diff --check" before |
|
9 committing. |
|
10 |
|
11 - Commit using Unix line endings (check the settings around "crlf" in |
|
12 git-config(1)). |
|
13 |
|
14 - Do not check in commented out code or unneeded files. |
|
15 |
|
16 - The first line of the commit message should be a short |
|
17 description (50 characters is the soft limit, excluding ticket |
|
18 number(s)), and should skip the full stop. |
|
19 |
|
20 - Associate the issue in the message. The first line should include |
|
21 the issue number in the form "(#XXXX) Rest of message". |
|
22 |
|
23 - The body should provide a meaningful commit message, which: |
|
24 |
|
25 - uses the imperative, present tense: "change", not "changed" or |
|
26 "changes". |
|
27 |
|
28 - includes motivation for the change, and contrasts its |
|
29 implementation with the previous behavior. |
|
30 |
|
31 - Make sure that you have tests for the bug you are fixing, or |
|
32 feature you are adding. |
|
33 |
|
34 - Make sure the test suites passes after your commit: |
|
35 `bundle exec rspec spec/acceptance` More information on [testing](#Testing) below |
|
36 |
|
37 - When introducing a new feature, make sure it is properly |
|
38 documented in the README.md |
|
39 |
|
40 * Submission: |
|
41 |
|
42 * Pre-requisites: |
|
43 |
|
44 - Make sure you have a [GitHub account](https://github.com/join) |
|
45 |
|
46 - [Create a ticket](https://tickets.puppetlabs.com/secure/CreateIssue!default.jspa), or [watch the ticket](https://tickets.puppetlabs.com/browse/) you are patching for. |
|
47 |
|
48 * Preferred method: |
|
49 |
|
50 - Fork the repository on GitHub. |
|
51 |
|
52 - Push your changes to a topic branch in your fork of the |
|
53 repository. (the format ticket/1234-short_description_of_change is |
|
54 usually preferred for this project). |
|
55 |
|
56 - Submit a pull request to the repository in the puppetlabs |
|
57 organization. |
|
58 |
|
59 The long version |
|
60 ================ |
|
61 |
|
62 1. Make separate commits for logically separate changes. |
|
63 |
|
64 Please break your commits down into logically consistent units |
|
65 which include new or changed tests relevant to the rest of the |
|
66 change. The goal of doing this is to make the diff easier to |
|
67 read for whoever is reviewing your code. In general, the easier |
|
68 your diff is to read, the more likely someone will be happy to |
|
69 review it and get it into the code base. |
|
70 |
|
71 If you are going to refactor a piece of code, please do so as a |
|
72 separate commit from your feature or bug fix changes. |
|
73 |
|
74 We also really appreciate changes that include tests to make |
|
75 sure the bug is not re-introduced, and that the feature is not |
|
76 accidentally broken. |
|
77 |
|
78 Describe the technical detail of the change(s). If your |
|
79 description starts to get too long, that is a good sign that you |
|
80 probably need to split up your commit into more finely grained |
|
81 pieces. |
|
82 |
|
83 Commits which plainly describe the things which help |
|
84 reviewers check the patch and future developers understand the |
|
85 code are much more likely to be merged in with a minimum of |
|
86 bike-shedding or requested changes. Ideally, the commit message |
|
87 would include information, and be in a form suitable for |
|
88 inclusion in the release notes for the version of Puppet that |
|
89 includes them. |
|
90 |
|
91 Please also check that you are not introducing any trailing |
|
92 whitespace or other "whitespace errors". You can do this by |
|
93 running "git diff --check" on your changes before you commit. |
|
94 |
|
95 2. Sending your patches |
|
96 |
|
97 To submit your changes via a GitHub pull request, we _highly_ |
|
98 recommend that you have them on a topic branch, instead of |
|
99 directly on "master". |
|
100 It makes things much easier to keep track of, especially if |
|
101 you decide to work on another thing before your first change |
|
102 is merged in. |
|
103 |
|
104 GitHub has some pretty good |
|
105 [general documentation](http://help.github.com/) on using |
|
106 their site. They also have documentation on |
|
107 [creating pull requests](http://help.github.com/send-pull-requests/). |
|
108 |
|
109 In general, after pushing your topic branch up to your |
|
110 repository on GitHub, you can switch to the branch in the |
|
111 GitHub UI and click "Pull Request" towards the top of the page |
|
112 in order to open a pull request. |
|
113 |
|
114 |
|
115 3. Update the related GitHub issue. |
|
116 |
|
117 If there is a GitHub issue associated with the change you |
|
118 submitted, then you should update the ticket to include the |
|
119 location of your branch, along with any other commentary you |
|
120 may wish to make. |
|
121 |
|
122 Testing |
|
123 ======= |
|
124 |
|
125 Getting Started |
|
126 --------------- |
|
127 |
|
128 Our puppet modules provide [`Gemfile`](./Gemfile)s which can tell a ruby |
|
129 package manager such as [bundler](http://bundler.io/) what Ruby packages, |
|
130 or Gems, are required to build, develop, and test this software. |
|
131 |
|
132 Please make sure you have [bundler installed](http://bundler.io/#getting-started) |
|
133 on your system, then use it to install all dependencies needed for this project, |
|
134 by running |
|
135 |
|
136 ```shell |
|
137 % bundle install |
|
138 Fetching gem metadata from https://rubygems.org/........ |
|
139 Fetching gem metadata from https://rubygems.org/.. |
|
140 Using rake (10.1.0) |
|
141 Using builder (3.2.2) |
|
142 -- 8><-- many more --><8 -- |
|
143 Using rspec-system-puppet (2.2.0) |
|
144 Using serverspec (0.6.3) |
|
145 Using rspec-system-serverspec (1.0.0) |
|
146 Using bundler (1.3.5) |
|
147 Your bundle is complete! |
|
148 Use `bundle show [gemname]` to see where a bundled gem is installed. |
|
149 ``` |
|
150 |
|
151 NOTE some systems may require you to run this command with sudo. |
|
152 |
|
153 If you already have those gems installed, make sure they are up-to-date: |
|
154 |
|
155 ```shell |
|
156 % bundle update |
|
157 ``` |
|
158 |
|
159 With all dependencies in place and up-to-date we can now run the tests: |
|
160 |
|
161 ```shell |
|
162 % bundle exec rake spec |
|
163 ``` |
|
164 |
|
165 This will execute all the [rspec tests](http://rspec-puppet.com/) tests |
|
166 under [spec/defines](./spec/defines), [spec/classes](./spec/classes), |
|
167 and so on. rspec tests may have the same kind of dependencies as the |
|
168 module they are testing. While the module defines in its [Modulefile](./Modulefile), |
|
169 rspec tests define them in [.fixtures.yml](./fixtures.yml). |
|
170 |
|
171 Some puppet modules also come with [beaker](https://github.com/puppetlabs/beaker) |
|
172 tests. These tests spin up a virtual machine under |
|
173 [VirtualBox](https://www.virtualbox.org/)) with, controlling it with |
|
174 [Vagrant](http://www.vagrantup.com/) to actually simulate scripted test |
|
175 scenarios. In order to run these, you will need both of those tools |
|
176 installed on your system. |
|
177 |
|
178 You can run them by issuing the following command |
|
179 |
|
180 ```shell |
|
181 % bundle exec rake spec_clean |
|
182 % bundle exec rspec spec/acceptance |
|
183 ``` |
|
184 |
|
185 This will now download a pre-fabricated image configured in the [default node-set](./spec/acceptance/nodesets/default.yml), |
|
186 install puppet, copy this module and install its dependencies per [spec/spec_helper_acceptance.rb](./spec/spec_helper_acceptance.rb) |
|
187 and then run all the tests under [spec/acceptance](./spec/acceptance). |
|
188 |
|
189 Writing Tests |
|
190 ------------- |
|
191 |
|
192 XXX getting started writing tests. |
|
193 |
|
194 If you have commit access to the repository |
|
195 =========================================== |
|
196 |
|
197 Even if you have commit access to the repository, you will still need to |
|
198 go through the process above, and have someone else review and merge |
|
199 in your changes. The rule is that all changes must be reviewed by a |
|
200 developer on the project (that did not write the code) to ensure that |
|
201 all changes go through a code review process. |
|
202 |
|
203 Having someone other than the author of the topic branch recorded as |
|
204 performing the merge is the record that they performed the code |
|
205 review. |
