# How to contribute

## Reporting issues

An issue might be a bug, an enhancement request or something in between. If you think you

have found a bug or if you want to request some enhancement, please:

1. Read the [Configuration](http://davdroid.bitfire.at/configuration) and [FAQ](http://davdroid.bitfire.at/faq/)

   pages carefully. The most common issues/usage challenges are explained there.

2. Search the Web for the problem, maybe ask competent friends or in forums.

3. Browse through the [open issues](https://github.com/rfc2822/davdroid/issues). You can

   also search the issues in the search field on top of the page. Please have a look

   into the closed issues, too, because many requests have already been handled (and can't/won't

   be fixed, for instance).

4. **[Fetch verbose logs](https://github.com/rfc2822/davdroid/wiki/How-to-view-the-logs) and prepare

   them. Remove `Authorization: Basic xxxxxx` headers and other private data.** Extracting the

   logs may be cumbersome work in the first time, but it's absolutely necessary in order to

   handle your issue.

5. [Create a new issue](https://github.com/rfc2822/davdroid/issues/new), containing

   * a useful summary of the problem ("Crash when syncing contacts with large photos" instead of "CRASH PLEASE HELP"),

   * your DAVdroid version and source ("DAVdroid 0.5.10 from F-Droid"),

   * your Android version and device model ("Samsung Galaxy S2 running Android 4.4.2 (CyanogenMod 11-20140504-SNAPSHOT-M6-i9100)"),

   * your CalDAV/CardDAV server software, version and hosting information ("OwnCloud 6, hosted on virtual server"),

   * a problem description, including **instructions on how to reproduce the problem** (we need to

     reproduce the problem before we can fix it!),

   * **verbose logs including the network traffic** (see step before). Enquote the logs with three backticks ```

     before and after, or post them onto http://gist.github.com and provide a link.

## Pull requests

We're very happy about pull requests for

* source code,

* documentation,

* translation (strings).

However, if you want to contribute source code, please talk with us in the

corresponding issue before because will only merge pull requests that

* match our product goals,

* have the necessary code quality,

* don't interfere with other near-term future development.

However, feel free to fork the repository and do your changes anyway

(that's why it's open-source). Just don't expect your strategic changes to be

merged if there's no consensus in the issue before.
