Please have a look here.
If you have a fix for some bug you found or any other improvement of the code and want to share it, please create a pull request.
Znuny is (at least for now) focused on security and bug fixes. Therefore we would like to politely ask you to not provide new features or changes in behavior via pull requests. See "Contributing new features and changes in behavior" below.
With the help of the OTRS code policy package you can check if your code matches the OTRS code style. It's based on TidyAll, extended by many plugins specific to OTRS.
When you made your changes and before you commit them, execute the code policy to let it check your changes. If executed without any parameters, the following command will check all changed files that haven't been committed yet. The command should be executed from within the Znuny base directory. You should stage your changes (via git add) before running it, so that you can afterwards see the changes made by the code policy package (via git diff), if any.
perl <path-to-your-code-policy-package>/bin/otrs.CodePolicy.pl
If you fix something, a test should be provided or extended to test your changes. You can find all tests in the directory scripts/test in your Znuny base directory. Ideally there already should exist one or more tests for the part of Znuny that your code changes. You then can update these tests to also test your fix. If in doubt, create a new test file specifically for your fix. Have a look at said existing tests to find out how to write tests.
You can execute a single test with the following command from within your Znuny base directory:
perl bin/otrs.Console.pl Dev::UnitTest::Run --verbose --test <path to test file>
If there is for example a test file scripts/test/Ticket/NumberGenerator.t you have to execute the following command (please note how to give the test file without the scripts/test/ prefix and without the .t suffix):
perl bin/otrs.Console.pl Dev::UnitTest::Run --verbose --test Ticket/NumberGenerator
As mentioned, the focus of Znuny is for now on security and bug fixes.
Currently, the only way to contribute new features to Znuny (or older OTRS versions) is to put your changes into a package (OPM). A package consists of a source OPM file and all files added or changed by you which will be copied to your Znuny installation directory upon installation of the package. The directory structure within your package must match the one of Znuny.
You then can build an installable package of your code with the following command, executed from within your Znuny base directory:
bin/otrs.Console.pl Dev::Package::Build --module-directory <path-to-the-base-directory-of-your-package> <path-to-the-sopm-file-of-your-package> <directory-to-put-in-the-created-opm-package-file>
The package name should always be prepended by your company name (e. g. MyCompany-PackageName). Example for building your package MyCompany-MyFirstPackage:
bin/otrs.Console.pl Dev::Package::Build --module-directory /path/to/MyCompany-MyFirstPackage/ /path/to/MyCompany-MyFirstPackage/MyCompany-MyFirstPackage.sopm /path/to/created/package/
You can find many open source packages from and for Znuny at GitHub, for example the package Znuny4OTRS-CTI. Have a look at them, especially their sopm file in the root directory.
