## Reporting Potential Security Issues

If you have encountered a potential security vulnerability, please **DO NOT** report it on the public
issue tracker: send it to us at [zf-security@zend.com](mailto:zf-security@zend.com) instead.
We will work with you to verify the vulnerability and patch it as soon as possible.

When reporting issues, please provide the following information:

- Component(s) affected
- A description indicating how to reproduce the issue
- A summary of the security vulnerability and impact

We request that you contact us via the email address above and give the project
contributors a chance to resolve the vulnerability and issue a new release prior
to any public exposure; this helps protect users and provides them with a chance
to upgrade and/or update in order to protect their applications.

For sensitive email communications, please use [our PGP key](http://framework.zend.com/zf-security-pgp-key.asc).

## RUNNING TESTS

> ### Note: testing versions prior to 2.4
>
> This component originates with Zend Framework 2. During the lifetime of ZF2,
> testing infrastructure migrated from PHPUnit 3 to PHPUnit 4. In most cases, no
> changes were necessary. However, due to the migration, tests may not run on
> versions < 2.4. As such, you may need to change the PHPUnit dependency if
> attempting a fix on such a version.

To run tests:

- Clone the repository:

  ```console
  $ git clone git@github.com:zendframework/zend-event-manager.git
  $ cd
  ```

- Install dependencies via composer:

  ```console
  $ curl -sS https://getcomposer.org/installer | php --
  $ ./composer.phar install
  ```

  If you don't have `curl` installed, you can also download `composer.phar` from https://getcomposer.org/

- Run the tests via `phpunit` and the provided PHPUnit config, like in this example:

  ```console
  $ ./vendor/bin/phpunit
  ```

You can turn on conditional tests with the phpunit.xml file.
To do so:

 -  Copy `phpunit.xml.dist` file to `phpunit.xml`
 -  Edit `phpunit.xml` to enable any specific functionality you
    want to test, as well as to provide test values to utilize.

## Running Coding Standards Checks

This component uses [phpcs](https://github.com/squizlabs/PHP_CodeSniffer) for coding
standards checks, and provides configuration for our selected checks.
`phpcs` is installed by default via Composer.

To run checks only:

```console
$ composer cs-check
```

`phpcs` also includes a tool for fixing most CS violations, `phpcbf`:


```console
$ composer cs-fix
```

If you allow `phpcbf` to fix CS issues, please re-run the tests to ensure
they pass, and make sure you add and commit the changes after verification.

## Recommended Workflow for Contributions

Your first step is to establish a public repository from which we can
pull your work into the master repository. We recommend using
[GitHub](https://github.com), as that is where the component is already hosted.

1. Setup a [GitHub account](http://github.com/), if you haven't yet
2. Fork the repository (http://github.com/zendframework/zend-event-manager)
3. Clone the canonical repository locally and enter it.

   ```console
   $ git clone git://github.com:zendframework/zend-event-manager.git
   $ cd zend-event-manager
   ```

4. Add a remote to your fork; substitute your GitHub username in the command
   below.

   ```console
   $ git remote add {username} git@github.com:{username}/zend-event-manager.git
   $ git fetch {username}
   ```

### Keeping Up-to-Date

Periodically, you should update your fork or personal repository to
match the canonical ZF repository. Assuming you have setup your local repository
per the instructions above, you can do the following:


```console
$ git checkout master
$ git fetch origin
$ git rebase origin/master
# OPTIONALLY, to keep your remote up-to-date -
$ git push {username} master:master
```

If you're tracking other branches -- for example, the "develop" branch, where
new feature development occurs -- you'll want to do the same operations for that
branch; simply substitute  "develop" for "master".

### Working on a patch

We recommend you do each new feature or bugfix in a new branch. This simplifies
the task of code review as well as the task of merging your changes into the
canonical repository.

A typical workflow will then consist of the following:

1. Create a new local branch based off either your master or develop branch.
2. Switch to your new local branch. (This step can be combined with the
   previous step with the use of `git checkout -b`.)
3. Do some work, commit, repeat as necessary.
4. Push the local branch to your remote repository.
5. Send a pull request.

The mechanics of this process are actually quite trivial. Below, we will
create a branch for fixing an issue in the tracker.

```console
$ git checkout -b hotfix/9295
Switched to a new branch 'hotfix/9295'
```

... do some work ...


```console
$ git commit
```

... write your log message ...


```console
$ git push {username} hotfix/9295:hotfix/9295

To ssh://git@github.com/{username}/zend-event-manager.git
   b5583aa..4f51698  HEAD -> master
```

To send a pull request, you have two options.

If using GitHub, you can do the pull request from there. Navigate to
your repository, select the branch you just created, and then select the
"Pull Request" button in the upper right. Select the user/organization
"zendframework" as the recipient.

If using your own repository - or even if using GitHub - you can use `git
format-patch` to create a patchset for us to apply; in fact, this is
**recommended** for security-related patches. If you use `format-patch`, please
send the patches as attachments to:

-  zf-devteam@zend.com for patches without security implications
-  zf-security@zend.com for security patches

#### What branch to issue the pull request against?

Which branch should you issue a pull request against?

- For fixes against the stable release, issue the pull request against the
  "master" branch.
- For new features, or fixes that introduce new elements to the public API (such
  as new public methods or properties), issue the pull request against the
  "develop" branch.

### Branch Cleanup

As you might imagine, if you are a frequent contributor, you'll start to
get a ton of branches both locally and on your remote.

Once you know that your changes have been accepted to the master
repository, we suggest doing some cleanup of these branches.

-  Local branch cleanup

   ```console
   $ git branch -d <branchname>
   ```

-  Remote branch removal

   ```console
   $ git push {username} :<branchname>
   ```
