1HOW TO CONTRIBUTE TO OpenSSL
2============================
3
4Please visit our [Getting Started] page for other ideas about how to contribute.
5
6  [Getting Started]: <https://www.openssl.org/community/getting-started.html>
7
8Development is done on GitHub in the [openssl/openssl] repository.
9
10  [openssl/openssl]: <https://github.com/openssl/openssl>
11
12To request new a feature, ask a question, or report a bug,
13please open an [issue on GitHub](https://github.com/openssl/openssl/issues).
14
15To submit a patch or implement a new feature, please open a
16[pull request on GitHub](https://github.com/openssl/openssl/pulls).
17If you are thinking of making a large contribution,
18open an issue for it before starting work, to get comments from the community.
19Someone may be already working on the same thing,
20or there may be special reasons why a feature is not implemented.
21
22To make it easier to review and accept your pull request, please follow these
23guidelines:
24
25 1. Anything other than a trivial contribution requires a [Contributor
26    License Agreement] (CLA), giving us permission to use your code.
27    If your contribution is too small to require a CLA (e.g., fixing a spelling
28    mistake), then place the text "`CLA: trivial`" on a line by itself below
29    the rest of your commit message separated by an empty line, like this:
30
31    ```
32        One-line summary of trivial change
33
34        Optional main body of commit message. It might contain a sentence
35        or two explaining the trivial change.
36
37        CLA: trivial
38    ```
39
40    It is not sufficient to only place the text "`CLA: trivial`" in the GitHub
41    pull request description.
42
43    [Contributor License Agreement]: <https://www.openssl.org/policies/cla.html>
44
45    To amend a missing "`CLA: trivial`" line after submission, do the following:
46
47    ```
48        git commit --amend
49        # add the line, save and quit the editor
50        git push -f [<repository> [<branch>]]
51    ```
52
53 2. All source files should start with the following text (with
54    appropriate comment characters at the start of each line and the
55    year(s) updated):
56
57    ```

61        this file except in compliance with the License.  You can obtain a copy
62        in the file LICENSE in the source distribution or at
63        https://www.openssl.org/source/license.html
64    ```
65
66 3. Patches should be as current as possible; expect to have to rebase
67    often. We do not accept merge commits, you will have to remove them
68    (usually by rebasing) before it will be acceptable.
69
70 4. Code provided should follow our [coding style] and compile without warnings.
71    There is a [Perl tool](util/check-format.pl) that helps
72    finding code formatting mistakes and other coding style nits.
73    Where `gcc` or `clang` is available, you should use the
74    `--strict-warnings` `Configure` option.  OpenSSL compiles on many varied
75    platforms: try to ensure you only use portable features.
76    Clean builds via GitHub Actions are required. They are started automatically
77    whenever a PR is created or updated by committers.
78
79    [coding style]: https://www.openssl.org/policies/technical/coding-style.html
80
81 5. When at all possible, code contributions should include tests. These can
82    either be added to an existing test, or completely new.  Please see
83    [test/README.md](test/README.md) for information on the test framework.
84
85 6. New features or changed functionality must include
86    documentation. Please look at the `.pod` files in `doc/man[1357]` for
87    examples of our style. Run `make doc-nits` to make sure that your
88    documentation changes are clean.
89
90 7. For user visible changes (API changes, behaviour changes, ...),
91    consider adding a note in [CHANGES.md](CHANGES.md).
92    This could be a summarising description of the change, and could
93    explain the grander details.
94    Have a look through existing entries for inspiration.
95    Please note that this is NOT simply a copy of git-log one-liners.
96    Also note that security fixes get an entry in [CHANGES.md](CHANGES.md).
97    This file helps users get more in-depth information of what comes
98    with a specific release without having to sift through the higher
99    noise ratio in git-log.
100
101 8. For larger or more important user visible changes, as well as
102    security fixes, please add a line in [NEWS.md](NEWS.md).
103    On exception, it might be worth adding a multi-line entry (such as
104    the entry that announces all the types that became opaque with
105    OpenSSL 1.1.0).
106    This file helps users get a very quick summary of what comes with a
107    specific release, to see if an upgrade is worth the effort.
108
109 9. Guidelines how to integrate error output of new crypto library modules
110    can be found in [crypto/err/README.md](crypto/err/README.md).
