# Activity Stream Pings
The Activity Stream system add-on sends various types of pings to the backend (HTTPS POST) [Onyx server](https://github.com/mozilla/onyx) :
- a `health` ping that reports whether or not a user has a custom about:home or about:newtab page
- a `session` ping that describes the ending of an Activity Stream session (a new tab is closed or refreshed), and
- an `event` ping that records specific data about individual user interactions while interacting with Activity Stream
- an `impression_stats` ping that records data about Pocket impressions and user interactions
Schema definitions/validations that can be used for tests can be found in `system-addon/test/schemas/pings.js`.

## Encoding and decoding of `user_prefs`
This encoding mapping was defined in `system-addon/lib/TelemetryFeed.jsm`
```eval_rst
+-------------------+------------------------+
| Preference | Encoded value (binary) |
+===================+========================+
| `showSearch` | 1 (00000001) |
+-------------------+------------------------+
| `showTopSites` | 2 (00000010) |
+-------------------+------------------------+
| `showTopStories` | 4 (00000100) |
+-------------------+------------------------+
| `showHighlights` | 8 (00001000) |
+-------------------+------------------------+
| `showSnippets` | 16 (00010000) |
+-------------------+------------------------+
| `showSponsored` | 32 (00100000) |
+-------------------+------------------------+
| `showCFRAddons` | 64 (01000000) |
+-------------------+------------------------+
| `showCFRFeatures` | 128 (10000000) |
+-------------------+------------------------+
| `showSponsoredTopSites` | 256 (100000000) |
+-------------------+------------------------+
```
Each item above could be combined with other items through bitwise OR (`|`) operation.
Examples:
- Everything is on, `user_prefs = 1 | 2 | 4 | 8 | 16 | 32 | 64 | 128 | 256 = 511`
- Everything is off, `user_prefs = 0`
- Only show search and Top Stories, `user_prefs = 1 | 4 = 5`
- Everything except Highlights, `user_prefs = 1 | 2 | 4 | 16 | 32 | 64 | 128 | 256 = 503`
Likewise, one can use bitwise AND (`&`) for decoding.
- Check if everything is shown, `user_prefs & (1 | 2 | 4 | 8 | 16 | 32 | 64 | 128 | 256)` or `user_prefs == 511`
- Check if everything is off, `user_prefs == 0`
- Check if search is shown, `user_prefs & 1`
- Check if both Top Sites and Top Stories are shown, `(user_prefs & 2) && (user_prefs & 4)`, or `(user_prefs & (2 | 4)) == (2 | 4)`
