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 a new 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 ``` 58 Copyright 20xx-20yy The OpenSSL Project Authors. All Rights Reserved. 59 60 Licensed under the Apache License 2.0 (the "License"). You may not use 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 [documentation policy] 71 and compile without warnings. 72 There is a [Perl tool](util/check-format.pl) that helps 73 finding code formatting mistakes and other coding style nits. 74 Where `gcc` or `clang` is available, you should use the 75 `--strict-warnings` `Configure` option. OpenSSL compiles on many varied 76 platforms: try to ensure you only use portable features. 77 Clean builds via GitHub Actions are required. They are started automatically 78 whenever a PR is created or updated by committers. 79 80 [coding style]: https://www.openssl.org/policies/technical/coding-style.html 81 [documentation policy]: https://openssl.org/policies/technical/documentation-policy.html 82 83 5. When at all possible, code contributions should include tests. These can 84 either be added to an existing test, or completely new. Please see 85 [test/README.md](test/README.md) for information on the test framework. 86 87 6. New features or changed functionality must include 88 documentation. Please look at the `.pod` files in `doc/man[1357]` for 89 examples of our style. Run `make doc-nits` to make sure that your 90 documentation changes are clean. 91 92 7. For user visible changes (API changes, behaviour changes, ...), 93 consider adding a note in [CHANGES.md](CHANGES.md). 94 This could be a summarising description of the change, and could 95 explain the grander details. 96 Have a look through existing entries for inspiration. 97 Please note that this is NOT simply a copy of git-log one-liners. 98 Also note that security fixes get an entry in [CHANGES.md](CHANGES.md). 99 This file helps users get more in-depth information of what comes 100 with a specific release without having to sift through the higher 101 noise ratio in git-log. 102 103 8. For larger or more important user visible changes, as well as 104 security fixes, please add a line in [NEWS.md](NEWS.md). 105 On exception, it might be worth adding a multi-line entry (such as 106 the entry that announces all the types that became opaque with 107 OpenSSL 1.1.0). 108 This file helps users get a very quick summary of what comes with a 109 specific release, to see if an upgrade is worth the effort. 110 111 9. Guidelines how to integrate error output of new crypto library modules 112 can be found in [crypto/err/README.md](crypto/err/README.md). 113
