+# What is cereal? [![cereal tests](https://github.com/commaai/cereal/workflows/tests/badge.svg?event=push)](https://github.com/commaai/cereal/actions) [![codecov](https://codecov.io/gh/commaai/cereal/branch/master/graph/badge.svg)](https://codecov.io/gh/commaai/cereal)
+
+cereal is both a messaging spec for robotics systems as well as generic high performance IPC pub sub messaging with a single publisher and multiple subscribers.
+
+Imagine this use case:
+* A sensor process reads gyro measurements directly from an IMU and publishes a `sensorEvents` packet
+* A calibration process subscribes to the `sensorEvents` packet to use the IMU
+* A localization process subscribes to the `sensorEvents` packet to use the IMU also
+
+
+## Messaging Spec
+
+You'll find the message types in [log.capnp](log.capnp). It uses [Cap'n proto](https://capnproto.org/capnp-tool.html) and defines one struct called `Event`.
+
+All `Events` have a `logMonoTime` and a `valid`. Then a big union defines the packet type.
+
+### Best Practices
+
+- **All fields must describe quantities in SI units**, unless otherwise specified in the field name.
+- In the context of the message they are in, field names should be completely unambiguous.
+- All values should be easy to plot and be human-readable with minimal parsing.
+
+### Maintaining backwards-compatibility
+
+When making changes to the messaging spec you want to maintain backwards-compatibility, such that old logs can
+be parsed with a new version of cereal. Adding structs and adding members to structs is generally safe, most other
+things are not. Read more details [here](https://capnproto.org/language.html).
+
+### Custom forks
+
+Forks of [openpilot](https://github.com/commaai/openpilot) might want to add things to the messaging
+spec, however this could conflict with future changes made in mainline cereal/openpilot. Rebasing against mainline openpilot
+then means breaking backwards-compatibility with all old logs of your fork. So we added reserved events in
+[custom.capnp](custom.capnp) that we will leave empty in mainline cereal/openpilot. **If you only modify those, you can ensure your
+fork will remain backwards-compatible with all versions of mainline cereal/openpilot and your fork.**
+
+## Pub Sub Backends
+
+cereal supports two backends, one based on [zmq](https://zeromq.org/) and another called [msgq](messaging/msgq.cc), a custom pub sub based on shared memory that doesn't require the bytes to pass through the kernel.
+
+Example
+---
+```python
+import cereal.messaging as messaging
+
+# in subscriber
+sm = messaging.SubMaster(['sensorEvents'])
+while 1:
+  sm.update()
+  print(sm['sensorEvents'])
+
+```
+
+```python
+# in publisher
+pm = messaging.PubMaster(['sensorEvents'])
+dat = messaging.new_message('sensorEvents', size=1)
+dat.sensorEvents[0] = {"gyro": {"v": [0.1, -0.1, 0.1]}}
+pm.send('sensorEvents', dat)
+```

+# MSGQ: A lock free single producer multi consumer message queue
+
+## What is MSGQ?
+MSGQ is a system to pass messages from a single producer to multiple consumers. All the consumers need to be able to receive all the messages. It is designed to be a high performance replacement for ZMQ-like SUB/PUB patterns. It uses a ring buffer in shared memory to efficiently read and write data. Each read requires a copy. Writing can be done without a copy, as long as the size of the data is known in advance.
+
+## Storage
+The storage for the queue consists of an area of metadata, and the actual buffer. The metadata contains:
+
+1. A counter to the number of readers that are active
+2. A pointer to the head of the queue for writing. From now on referred to as *write pointer*
+3. A cycle counter for the writer. This counter is incremented when the writer wraps around
+4. N pointers, pointing to the current read position for all the readers. From now on referred to as *read pointer*
+5. N counters,  counting the number of cycles for all the readers
+6. N booleans, indicating validity for all the readers. From now on referred to as *validity flag*
+
+The counter and the pointer are both 32 bit values, packed into 64 bit so they can be read and written atomically.
+
+The data buffer is a ring buffer. All messages are prefixed by an 8 byte size field, followed by the data. A size of -1 indicates a wrap-around, and means the next message is stored at the beginning of the buffer.
+
+
+## Writing
+Writing involves the following steps:
+
+1. Check if the area that is to be written overlaps with any of the read pointers, mark those readers as invalid by clearing the validity flag.
+2. Write the message
+3. Increase the write pointer by the size of the message
+
+In case there is not enough space at the end of the buffer, a special empty message with a prefix of -1 is written. The cycle counter is incremented by one. In this case step 1 will check there are no read pointers pointing to the remainder of the buffer. Then another write cycle will start with the actual message.
+
+There always needs to be 8 bytes of empty space at the end of the buffer. By doing this there is always space to write the -1.
+
+## Reset reader
+When the reader is lagging too much behind the read pointer becomes invalid and no longer points to the beginning of a valid message. To reset a reader to the current write pointer, the following steps are performed:
+
+1. Set valid flag
+2. Set read cycle counter to that of the writer
+3. Set read pointer to write pointer
+
+## Reading
+Reading involves the following steps:
+
+1. Read the size field at the current read pointer
+2. Read the validity flag
+3. Copy the data out of the buffer
+4. Increase the read pointer by the size of the message
+5. Check the validity flag again
+
+Before starting the copy, the valid flag is checked. This is to prevent a race condition where the size prefix was invalid, and the read could read outside of the buffer. Make sure that step 1 and 2 are not reordered by your compiler or CPU.
+
+If a writer overwrites the data while it's being copied out, the data will be invalid. Therefore the validity flag is also checked after reading it. The order of step 4 and 5 does not matter.
+
+If at steps 2 or 5 the validity flag is not set, the reader is reset. Any data that was already read is discarded. After the reader is reset, the reading starts from the beginning.
+
+If a message with size -1 is encountered, step 3 and 4 are replaced by increasing the cycle counter and setting the read pointer to the beginning of the buffer. After that another read is performed.
