1 HOW TO CONTRIBUTE TO OpenSSL
2 ============================
4 Please visit our [Getting Started][gs] page for other ideas about how to contribute.
6 [gs]: https://www.openssl.org/community/getting-started.html
8 Development is done on GitHub in the [openssl/openssl][gh] repository.
10 [gh]: https://github.com/openssl/openssl
12 To request new features or report bugs, please open an issue on GitHub
14 To submit a patch, please open a pull request on GitHub. If you are thinking
15 of making a large contribution, open an issue for it before starting work,
16 to get comments from the community. Someone may be already working on
17 the same thing or there may be reasons why that feature isn't implemented.
19 To make it easier to review and accept your pull request, please follow these
22 1. Anything other than a trivial contribution requires a [Contributor
23 License Agreement][CLA] (CLA), giving us permission to use your code.
24 If your contribution is too small to require a CLA (e.g. fixing a spelling
25 mistake), place the text "`CLA: trivial`" on a line by itself separated by
26 an empty line from the rest of the commit message. It is not sufficient to
27 only place the text in the GitHub pull request description.
29 [CLA]: https://www.openssl.org/policies/cla.html
31 To amend a missing "`CLA: trivial`" line after submission, do the following:
35 [add the line, save and quit the editor]
39 2. All source files should start with the following text (with
40 appropriate comment characters at the start of each line and the

47 this file except in compliance with the License. You can obtain a copy

49 https://www.openssl.org/source/license.html
52 3. Patches should be as current as possible; expect to have to rebase
53 often. We do not accept merge commits, you will have to remove them
54 (usually by rebasing) before it will be acceptable.
56 4. Patches should follow our [coding style][] and compile without warnings.
57 Where gcc or clang is available you should use the
58 --strict-warnings Configure option. OpenSSL compiles on many varied
59 platforms: try to ensure you only use portable features. Clean builds
60 via Travis and AppVeyor are required, and they are started automatically
61 whenever a PR is created or updated.
63 [coding style]: https://www.openssl.org/policies/codingstyle.html
65 5. When at all possible, patches should include tests. These can
66 either be added to an existing test, or completely new. Please see
67 test/README for information on the test framework.
69 6. New features or changed functionality must include
70 documentation. Please look at the "pod" files in doc/man[1357] for
71 examples of our style. Run "make doc-nits" to make sure that your
72 documentation changes are clean.
74 7. For user visible changes (API changes, behaviour changes, ...),
75 consider adding a note in [CHANGES.md](CHANGES.md).
76 This could be a summarising description of the change, and could
77 explain the grander details.
78 Have a look through existing entries for inspiration.
79 Please note that this is NOT simply a copy of git-log one-liners.
80 Also note that security fixes get an entry in CHANGES.md.
81 This file helps users get more in depth information of what comes
82 with a specific release without having to sift through the higher
83 noise ratio in git-log.
85 8. For larger or more important user visible changes, as well as
86 security fixes, please add a line in [NEWS.md](NEWS.md).
87 On exception, it might be worth adding a multi-line entry (such as
88 the entry that announces all the types that became opaque with

91 specific release, to see if an upgrade is worth the effort.
