# Changelog
## Version `v1.0.0`
Significant improvements to the architecture, API and design of the library have been part of `v1.0.0`.
Upgrading should be rather simple for most users though, since the public API has not changed a lot
and only in places which are not used too frequently.
A lot of effort has been put into this summary to document as many changes as possible.
It is impossible to give a guarantee about the completeness of this list though.
You should cover your uses of the library with tests yourself as well.
The following summary compares `v0.3.0` to `v1.0.0`.
### Breaking Changes
- The library does now require PHP 7.4 and supports PHP 8.0. This move was made with the clear intention to drop support for PHP 7.4 at some point.
- The primary interface and class of the library have been renamed to StudlyCaps to follow PSR-2:
- `\PhpMqtt\Client\Contracts\MQTTClient` &rarr; `\PhpMqtt\Client\Contracts\MqttClient`
- `\PhpMqtt\Client\MQTTClient` &rarr; `\PhpMqtt\Client\MqttClient`
- `\PhpMqtt\Client\Exceptions\MQTTClientException` &rarr; `\PhpMqtt\Client\Exceptions\MqttClientException`
- Protocol specific logic has been extracted from the `MQTTClient` class to a new interface `\PhpMqtt\Client\Contracts\MessageProcessor` and the respective implementation for MQTT 3.1, `\PhpMqtt\Client\MessageProcessors\Mqtt31MessageProcessor`.
- The `MessageProcessor` is responsible for parsing and building packages on a byte level.
- Splitting the logic from the main class did not only reduce the overall complexity of the class, it also made testing a lot easier and builds a solid foundation for future development and extension by implementing more protocol versions (like MQTT 5).
- Some `protected` properties have been changed to `private` to ensure they are not manipulated outside the offered scope, which is enforced through getters and setters. This change only affects users which actively inherited their own implementation from the library.
- The QoS 2 message flow is now implemented properly and should just work.
#### Connection Settings
- The `$caFile` parameter of the `MQTTClient` constructor as well as the `$username` and `$password` parameters of the `MQTTClient::connect()` method have been moved to the `ConnectionSettings` class.
- The `ConnectionSettings` use fluent setters for configuration now ([see README](README.md)).
- The `ConnectionSettings`` passed to `MQTTClient::connect()` are now validated and may not contain invalid configuration. In case of invalid configuration, a `\PhpMqtt\Client\Exceptions\ConfigurationInvalidException` is thrown.
- Additional TLS options have been added to the `ConnectionSettings` to support more uses cases with secured connections.
#### Methods
- Most methods can now throw a `\PhpMqtt\Client\Exceptions\RepositoryException` if an interaction with the repository fails. This should happen with the `MemoryRepository` only in exceptional situations, but when implementing persisted repositories, this may happen more frequently and should therefore be considered.
- The `MQTTClient::connect()` method had a parameter called `$sendCleanSessionFlag` while the `MqttClient::connect()` method has the same parameter, but called `$useCleanSession`. The parameters `$username` and `$password` have been removed entirely and are now part of the `ConnectionSettings`.
- The method `MQTTClient::close()` has been renamed to `MqttClient::disconnect()`.
- The parameter `$topic` of `MQTTClient::subscribe()` has been renamed to `$topicFilter` to reflect its meaning (which is a topic, but with wildcards). The `$callback` parameter can be `null` now and has `null` as default.
- The parameter `$topic` of `MQTTClient::unsubscribe()` has been renamed to `$topicFilter` as well.
#### Exceptions
- New exceptions have been introduced and old ones were removed. All exceptions inherit from `\PhpMqtt\Client\Exceptions\MqttClientException` as base. You should ensure your calls to methods of the `MqttClient` handle the exceptions appropriately.
- The exception constants previously defined on the `\PhpMqtt\Client\MQTTClient` class have been moved to the respective exception classes. This change only affects you if you used these constants to render detailed exception information for your users.
#### Repositories
- The `\PhpMqtt\Client\Contracts\Repository` interface has been changed significantly and summarizing all changes would be quite hard anyway. We therefore encourage you to have a look at the interface again and update your own implementation(s) of it, if you have any.
#### Logger
- The `\PhpMqtt\Client\Logger` implementation of `Psr\Log\LoggerInterface` does now decorate the log output with details about the MQTT client (format: `MQTT [{host}:{port}] [{clientId}] {message}`).
### Additions
- It is now possible to register event handlers for received messages. In combination with subscriptions without a callback, this allows to use centralized logic for multiple subscriptions. It also can be used for centralized logging, for example.
- A lot of unit and integration tests have been added which cover most parts of the library, especially the non-exception paths.
- All unit tests, integration tests, and the code style are enforced using a GitHub Actions workflow which runs under Ubuntu against multiple MQTT brokers (currently Mosquitto, HiveMQ and EMQ X). Contributing became easier therefore, but we expect that tests are added for changes and additions.
- To run the tests locally, an MQTT broker without authorization needs to run at `localhost:1883` (or the configuration in `phpunit.xml` is changed instead).
- The project is now analyzed using [sonarcloud.io](https://sonarcloud.io/dashboard?id=php-mqtt_client) which helps us keep up the high standards of the library.
#### Methods
- `MqttClient::isConnected()`: returns `true` if a connection is established (socket opened), and `false` otherwise.
- `MqttClient::getReceivedBytes()`: returns the number of raw bytes received from the broker (this includes meta information and not only message contents).
- `MqttClient::getSentBytes()`: returns the number of raw bytes sent to the broker (this includes meta information and not only message contents).
### Removals
_No functionality has been removed in this version._

[`php-mqtt/client`](https://packagist.org/packages/php-mqtt/client) was created by, and is maintained
by [Marvin Mall](https://github.com/namoshek).
It allows you to connect to an MQTT broker where you can publish messages and subscribe to topics.
The current implementation supports all QoS levels ([with limitations](#limitations)).
## Installation
The package is available on [packagist.org](https://packagist.org/packages/php-mqtt/client) and can be installed using `composer`:
```bash
composer require php-mqtt/client
```
The package requires PHP version 7.4 or higher.
## Usage
In the following, only a few very basic examples are given. For more elaborate examples, have a look at the
[`php-mqtt/client-examples` repository](https://github.com/php-mqtt/client-examples).
### Publish
A very basic publish example using QoS 0 requires only three steps: connect, publish and disconnect
```php
$server = 'some-broker.example.com';
$port = 1883;
$clientId = 'test-publisher';
$mqtt = new \PhpMqtt\Client\MqttClient($server, $port, $clientId);
$mqtt->connect();
$mqtt->publish('php-mqtt/client/test', 'Hello World!', 0);
$mqtt->disconnect();
```
If you do not want to pass a `$clientId`, a random one will be generated for you. This will basically force a clean session implicitly.
Be also aware that most of the methods can throw exceptions. The above example does not add any exception handling for brevity.
### Subscribe
Subscribing is a little more complex than publishing as it requires to run an event loop which reads, parses and handles messages from the broker:
```php
$server = 'some-broker.example.com';
$port = 1883;
$clientId = 'test-subscriber';
$mqtt = new \PhpMqtt\Client\MqttClient($server, $port, $clientId);
$mqtt->connect();
$mqtt->subscribe('php-mqtt/client/test', function ($topic, $message, $retained, $matchedWildcards) {
echo sprintf("Received message on topic [%s]: %s\n", $topic, $message);
}, 0);
$mqtt->loop(true);
$mqtt->disconnect();
```
While the loop is active, you can use `$mqtt->interrupt()` to send an interrupt signal to the loop.
This will terminate the loop before it starts its next iteration. You can call this method using `pcntl_signal(SIGINT, $handler)` for example:
```php
pcntl_async_signals(true);
$clientId = 'test-subscriber';
$mqtt = new \PhpMqtt\Client\MqttClient($server, $port, $clientId);
pcntl_signal(SIGINT, function (int $signal, $info) use ($mqtt) {
$mqtt->interrupt();
});
$mqtt->connect();
$mqtt->subscribe('php-mqtt/client/test', function ($topic, $message, $retained, $matchedWildcards) {
echo sprintf("Received message on topic [%s]: %s\n", $topic, $message);
}, 0);
$mqtt->loop(true);
$mqtt->disconnect();
```
### Client Settings
As shown in the examples above, the `MqttClient` takes the server, port and client id as first, second and third parameter.
As fourth parameter, the protocol level can be passed. Currently supported is MQTT v3.1,
available as constant `MqttClient::MQTT_3_1`.
A fifth parameter allows passing a repository (currently, only a `MemoryRepository` is available by default).
Lastly, a logger can be passed as sixth parameter. If none is given, a null logger is used instead.
Example:
```php
$mqtt = new \PhpMqtt\Client\MqttClient(
$server,
$port,
$clientId,
\PhpMqtt\Client\MqttClient::MQTT_3_1,
new \PhpMqtt\Client\Repositories\MemoryRepository(),
new Logger()
);
```
The `Logger` must implement the `Psr\Log\LoggerInterface`.
### Connection Settings
The `connect()` method of the `MqttClient` takes two optional parameters:
1. A `ConnectionSettings` instance
2. A `boolean` flag indicating whether a clean session should be requested (a random client id does this implicitly)
Example:
```php
$mqtt = new \PhpMqtt\Client\MqttClient($server, $port, $clientId);
$connectionSettings = (new \PhpMqtt\Client\ConnectionSettings)
->setConnectTimeout(3)
->setUseTls(true)
->setTlsSelfSignedAllowed(true);
$mqtt->connect($connectionSettings, true);
```
The `ConnectionSettings` class provides a few settings through a fluent interface. The type itself is immutable,
and a new `ConnectionSettings` instance will be created for each added option.
This also prevents changes to the connection settings after a connection has been established.
The following is a complete list of options with their respective default:
```php
$connectionSettings = (new \PhpMqtt\Client\ConnectionSettings)
// The username used for authentication when connecting to the broker.
->setUsername(null)
// The password used for authentication when connecting to the broker.
->setPassword(null)
// Whether to use a blocking socket when publishing messages or not.
// Normally, this setting can be ignored. When publishing large messages with multiple kilobytes in size,
// a blocking socket may be required if the receipt buffer of the broker is not large enough.
//
// Note: This setting has no effect on subscriptions, only on the publishing of messages.
->useBlockingSocket(false)
// The connect timeout defines the maximum amount of seconds the client will try to establish
// a socket connection with the broker. The value cannot be less than 1 second.
->setConnectTimeout(60)
// The socket timeout is the maximum amount of idle time in seconds for the socket connection.
// If no data is read or sent for the given amount of seconds, the socket will be closed.
// The value cannot be less than 1 second.
->setSocketTimeout(5)
// The resend timeout is the number of seconds the client will wait before sending a duplicate
// of pending messages without acknowledgement. The value cannot be less than 1 second.
->setResendTimeout(10)
// This flag determines whether the client will try to reconnect automatically
// if it notices a disconnect while sending data.
// The setting cannot be used together with the clean session flag.
->setReconnectAutomatically(false)
// Defines the maximum number of reconnect attempts until the client gives up.
// This setting is only relevant if setReconnectAutomatically() is set to true.
->setMaxReconnectAttempts(3)
// Defines the delay between reconnect attempts in milliseconds.
// This setting is only relevant if setReconnectAutomatically() is set to true.
->setDelayBetweenReconnectAttempts(0)
// The keep alive interval is the number of seconds the client will wait without sending a message
// until it sends a keep alive signal (ping) to the broker. The value cannot be less than 1 second
// and may not be higher than 65535 seconds. A reasonable value is 10 seconds (the default).
->setKeepAliveInterval(10)
// If the broker should publish a last will message in the name of the client when the client
// disconnects abruptly, this setting defines the topic on which the message will be published.
//
// A last will message will only be published if both this setting as well as the last will
// message are configured.
->setLastWillTopic(null)
// If the broker should publish a last will message in the name of the client when the client
// disconnects abruptly, this setting defines the message which will be published.
//
// A last will message will only be published if both this setting as well as the last will
// topic are configured.
->setLastWillMessage(null)
// The quality of service level the last will message of the client will be published with,
// if it gets triggered.
->setLastWillQualityOfService(0)
// This flag determines if the last will message of the client will be retained, if it gets
// triggered. Using this setting can be handy to signal that a client is offline by publishing
// a retained offline state in the last will and an online state as first message on connect.
->setRetainLastWill(false)
// This flag determines if TLS should be used for the connection. The port which is used to
// connect to the broker must support TLS connections.
->setUseTls(false)
// This flag determines if the peer certificate is verified, if TLS is used.
->setTlsVerifyPeer(true)
// This flag determines if the peer name is verified, if TLS is used.
->setTlsVerifyPeerName(true)
// This flag determines if self signed certificates of the peer should be accepted.
// Setting this to TRUE implies a security risk and should be avoided for production
// scenarios and public services.
->setTlsSelfSignedAllowed(false)
// The path to a Certificate Authority certificate which is used to verify the peer
// certificate, if TLS is used.
->setTlsCertificateAuthorityFile(null)
// The path to a directory containing Certificate Authority certificates which are
// used to verify the peer certificate, if TLS is used.
->setTlsCertificateAuthorityPath(null)
// The path to a client certificate file used for authentication, if TLS is used.
//
// The client certificate must be PEM encoded. It may optionally contain the
// certificate chain of issuers.
->setTlsClientCertificateFile(null)
// The path to a client certificate key file used for authentication, if TLS is used.
//
// This option requires ConnectionSettings::setTlsClientCertificateFile() to be used as well.
->setTlsClientCertificateKeyFile(null)
// The passphrase used to decrypt the private key of the client certificate,
// which in return is used for authentication, if TLS is used.
//
// This option requires ConnectionSettings::setTlsClientCertificateFile() and
// ConnectionSettings::setTlsClientCertificateKeyFile() to be used as well.
->setTlsClientCertificateKeyPassphrase(null);
```

## Limitations
- Message flows with a QoS level higher than 0 are not persisted as the default implementation uses an in-memory repository for data.
To avoid issues with broken message flows, use the clean session flag to indicate that you don't care about old data.
It will not only instruct the broker to consider the connection new (without previous state), but will also reset the registered repository.
## Developing & Testing
### Certificates (TLS)
To run the tests (especially the TLS tests), you will need to create certificates. A command has been provided for this:
```sh
sh create-certificates.sh
```
This will create all required certificates in the `.ci/tls/` directory. The same script is used for continuous integration as well.
### MQTT Broker for Testing
Running the tests expects an MQTT broker to be running. The easiest way to run an MQTT broker is through Docker:
```sh
docker run --rm -it \
-p 1883:1883 \
-p 1884:1884 \
-p 8883:8883 \
-p 8884:8884 \
-v $(pwd)/.ci/tls:/mosquitto-certs \
-v $(pwd)/.ci/mosquitto.conf:/mosquitto/config/mosquitto.conf \
-v $(pwd)/.ci/mosquitto.passwd:/mosquitto/config/mosquitto.passwd \
eclipse-mosquitto:1.6
```
When run from the project directory, this will spawn a Mosquitto MQTT broker configured with the generated TLS certificates and a custom configuration.
In case you intend to run a different broker or using a different method, or use a public broker instead,
you will need to adjust the environment variables defined in `phpunit.xml` accordingly.
