Image Manifest - a document describing the components that make up a container image 描述了容器镜像的组件
mediaType
application/vnd.oci.image.layer.v1.tar application/vnd.oci.image.layer.v1.tar+gzip application/vnd.oci.image.layer.nondistributable.v1.tar application/vnd.oci.image.layer.nondistributable.v1.tar+gzip Image Index - an annotated index of image manifests Image Layout - a filesystem layout representing the contents of an image
镜像每层的内容可能类似tar,zip的压缩文件，nfs的共享文件或者http/ftp/rsync的网络文件
+gzip Media Types
The media type application/vnd.oci.image.layer.v1.tar+gzip represents an application/vnd.oci.image.layer.v1.tar payload which has been compressed with gzip.
The media type application/vnd.oci.image.layer.nondistributable.v1.tar+gzip represents an application/vnd.oci.image.layer.nondistributable.v1.tar payload which has been compressed with gzip.
+zstd Media Types
The media type application/vnd.oci.image.layer.v1.tar+zstd represents an application/vnd.oci.image.layer.v1.tar payload which has been compressed with zstd.
The media type application/vnd.oci.image.layer.nondistributable.v1.tar+zstd represents an application/vnd.oci.image.layer.nondistributable.v1.tar payload which has been compressed with zstd.
Distributable Format
Layer Changesets for the media type application/vnd.oci.image.layer.v1.tar MUST be packaged in tar archive.
Layer Changesets for the media type application/vnd.oci.image.layer.v1.tar MUST NOT include duplicate entries for file paths in the resulting tar archive.
File Types支持的文件类型
regular files directories sockets symbolic links block devices character devices FIFOs
Non-Distributable Layers
Due to legal requirements, certain layers may not be regularly distributable. Such “non-distributable” layers are typically downloaded directly from a distributor but never uploaded.
Non-distributable layers SHOULD be tagged with an alternative mediatype of application/vnd.oci.image.layer.nondistributable.v1.tar. Implementations SHOULD NOT upload layers tagged with this media type; however, such a media type SHOULD NOT affect whether an implementation downloads the layer.
Descriptors referencing non-distributable layers MAY include urls for downloading these layers directly; however, the presence of the urls field SHOULD NOT be used to determine whether or not a layer is non-distributable.
Filesystem Layer - a changeset that describes a container’s filesystem 该文档描述了如何序列化文件和文件的变化比如移除文件放到一个blob称layer。
Image Configuration - a document determining layer ordering and configuration of the image suitable for translation into a runtime bundle 定义了layer的顺序和将image转换成运行的bundle
OCI 镜像是一个有序的文件层的集合和在容器运行环境中根据执行参数而改变。
Layer
Image filesystems are composed of layers.
Each layer represents a set of filesystem changes in a tar-based layer format, recording files to be added, changed, or deleted relative to its parent layer. 每层是根据父层记录文件的增加修改和删除。
Layers do not have configuration metadata such as environment variables or default arguments - these are properties of the image as a whole rather than any particular layer. 层没有配置环境变量等元数据，环境变量是针对整个镜像而不是单个层的。
Using a layer-based or union filesystem such as AUFS, or by computing the diff from filesystem snapshots, the filesystem changeset can be used to present a series of image layers as if they were one cohesive filesystem. 通过计算文件系统快照的不同，文件系统改变集合代表一系列的镜像层。
Image JSON
Each image has an associated JSON structure which describes some basic information about the image such as date created, author, as well as execution/runtime configuration like its entrypoint, default arguments, networking, and volumes. 每个镜像文件有一个JSON结构的文件，信息包括创建时间，作者，以及entrypoint和默认的参数、网络、volume等。
The JSON structure also references a cryptographic hash of each layer used by the image, and provides history information for those layers.
This JSON is considered to be immutable, because changing it would change the computed ImageID.
Changing it means creating a new derived image, instead of changing the existing image.
Layer DiffID
Layer ChainID 根据Ln层生成Ln+1层的chainID
ChainID(L₀) = DiffID(L₀) ChainID(L₀|…|Lₙ₋₁|Lₙ) = Digest(ChainID(L₀|…|Lₙ₋₁) + ” ” + DiffID(Lₙ))
Let’s expand the definition of ChainID(A|B|C) to explore its internal structure:
ChainID(A) = DiffID(A) ChainID(A|B) = Digest(ChainID(A) + ” ” + DiffID(B)) ChainID(A|B|C) = Digest(ChainID(A|B) + ” ” + DiffID(C))
ImageID 每个镜像ID是它的配置文件的SHA256的hash值。
Properties
Note: Any OPTIONAL field MAY also be set to null, which is equivalent to being absent.
created string, OPTIONAL
An combined date and time at which the image was created, formatted as defined by RFC 3339, section 5.6.
author string, OPTIONAL
Gives the name and/or email address of the person or entity which created and is responsible for maintaining the image.
architecture string, REQUIRED
The CPU architecture which the binaries in this image are built to run on. Configurations SHOULD use, and implementations SHOULD understand, values listed in the Go Language document for GOARCH.
os string, REQUIRED
The name of the operating system which the image is built to run on. Configurations SHOULD use, and implementations SHOULD understand, values listed in the Go Language document for GOOS.
config object, OPTIONAL
The execution parameters which SHOULD be used as a base when running a container using the image. This field can be null, in which case any execution parameters should be specified at creation of the container.
User string, OPTIONAL
The username or UID which is a platform-specific structure that allows specific control over which user the process run as. This acts as a default value to use when the value is not specified when creating a container. For Linux based systems, all of the following are valid: user, uid, user:group, uid:gid, uid:group, user:gid. If group/gid is not specified, the default group and supplementary groups of the given user/uid in /etc/passwd from the container are applied.
ExposedPorts object, OPTIONAL
A set of ports to expose from a container running this image. Its keys can be in the format of: port/tcp, port/udp, port with the default protocol being tcp if not specified. These values act as defaults and are merged with any specified when creating a container. NOTE: This JSON structure value is unusual because it is a direct JSON serialization of the Go type map[string]struct{} and is represented in JSON as an object mapping its keys to an empty object.
Env array of strings, OPTIONAL
Entries are in the format of VARNAME=VARVALUE. These values act as defaults and are merged with any specified when creating a container.
Entrypoint array of strings, OPTIONAL
A list of arguments to use as the command to execute when the container starts. These values act as defaults and may be replaced by an entrypoint specified when creating a container.
Cmd array of strings, OPTIONAL
Default arguments to the entrypoint of the container. These values act as defaults and may be replaced by any specified when creating a container. If an Entrypoint value is not specified, then the first entry of the Cmd array SHOULD be interpreted as the executable to run.
Volumes object, OPTIONAL
A set of directories describing where the process is likely write data specific to a container instance. NOTE: This JSON structure value is unusual because it is a direct JSON serialization of the Go type map[string]struct{} and is represented in JSON as an object mapping its keys to an empty object.
WorkingDir string, OPTIONAL
Sets the current working directory of the entrypoint process in the container. This value acts as a default and may be replaced by a working directory specified when creating a container.
Labels object, OPTIONAL
The field contains arbitrary metadata for the container. This property MUST use the annotation rules.
StopSignal string, OPTIONAL
The field contains the system call signal that will be sent to the container to exit. The signal can be a signal name in the format SIGNAME, for instance SIGKILL or SIGRTMIN+3.
rootfs object, REQUIRED
The rootfs key references the layer content addresses used by the image. This makes the image config hash depend on the filesystem hash.
type string, REQUIRED
MUST be set to layers. Implementations MUST generate an error if they encounter a unknown value while verifying or unpacking an image.
diff_ids array of strings, REQUIRED An array of layer content hashes (DiffIDs), in order from first to last. history array of objects, OPTIONAL
Describes the history of each layer. The array is ordered from first to last. The object has the following fields:
created string, OPTIONAL
A combined date and time at which the layer was created, formatted as defined by RFC 3339, section 5.6.
author string, OPTIONAL The author of the build point. created_by string, OPTIONAL The command which created the layer. comment string, OPTIONAL A custom message set when creating the layer. empty_layer boolean, OPTIONAL
This field is used to mark if the history item created a filesystem diff. It is set to true if this history item doesn’t correspond to an actual layer in the rootfs section (for example, Dockerfile’s ENV command results in no change to the filesystem).
Any extra fields in the Image JSON struct are considered implementation specific and MUST be ignored by any implementations which are unable to interpret them.
Whitespace is OPTIONAL and implementations MAY have compact JSON with no whitespace.
Conversion - a document describing how this translation should occur
Descriptor - a reference that describes the type, metadata and content address of referenced content
OCI镜像的层是通过Merkle树有向无循环调度来组织的。

Mum-of-five's 'embarrassment' at using food banks to feed children
Heather, from Camborne in Devon, is one of three families to appear on ITV's Exposure: Britain's Hidden Hunger and lay bare the struggles at juggling paying bills and putting food on the table
by Amber Hicks, Shannon Hards, https://www.facebook.com/dailymirror/A mum has admitted to feeling "embarrassed" and a "failure" for having to rely on food banks to feed her five children and husband.
Heather, who has asked her surname not to be published, says the summer holidays are the hardest because she can't rely on school meals to feed her kids, reports Cornwall Live.
She will appear on new ITV documentary Exposure: Britain's Hidden Hunger tonight (Thursday).
The show follows three families who are struggling to feed their children at a time when in Britain, the world's fifth largest economy, an estimated 14 million people - including four million youngsters - are living in poverty.
Heather's husband, Mike, has a job in retail on £8.20 an hour but the couple can't afford to feed their brood on his wages and family benefits and are forced to resort to the food bank.
She said: "I think I’ve been reliant on the food bank every time the holidays have come for as long as I can remember. Without that I don’t know what we’d do.
"It’s either pay your bills or put food on the table and you really see that in the six weeks' holidays."
Mike added: "We don’t have any luxuries or anything like that.

"I’m going to work as many hours as I can just to put food on the table, pay the bills, keep the debt collectors out the door, that’s all I’m doing but that in itself is empty."
He added: "I don’t want to be saying, ‘no, you can’t have that piece of bread because it needs to be for breakfast in the morning’ or whatever it is."
The couple admitted that they both felt humiliated to ask for support from the local food bank.
Mike said: "I don’t like going into the building because I feel embarrassed I suppose."
Heather added: "It’s a pride thing, even when I go to ask for vouchers, usually at my doctor’s, it’s like I check to see if anyone is around and I go under my breath, 'can I have some food bank vouchers please?'
"It’s something you don’t want people seeing."
Mike said: "It does feel embarrassing but we’ve got no choice. It makes me feel like an inch tall to think that I’m working and I’m taking food away from someone that may need it more but I know that we wouldn’t survive without it.
"We wouldn’t be able to provide every meal for our children."
Heather said she would like to obtain qualifications in journalism, enabling her to gain employment and provide for her family.
She added: "I don’t want to rely on the food bank. I want to be at a point where I don’t have to rely on the food bank because it makes you feel like a failure, it makes you feel like you aren’t providing for your children, which is a really horrible feeling."
Heather admitted that she was left hurt by several comments she has seen online since details were shared about the show.
She said: “I’m upset at the comments when people haven’t even seen the film yet and they don’t know me.
“Lots of low-income families are struggling and I took the chance to speak out about it so that everyone is aware.
 We can’t help if my husband’s hours are low and he works all that he can.
“I’m in ill health so am struggling myself but now that my daughter has started school, I’ll be trying to get some work too.”
Speaking ahead of the show, Heather said: “I am nervous about tonight’s episode but it is nice to know I am helping people. I am trying to help people be aware that we are all embarrassed to use food banks but hopefully if someone talks about it the shame will go away.”
- Exposure: Britain's Hidden Hunger will air Thursday night at 10.45pm on ITV.

In the previous chapter "Set Up" we already learned that Event Engine loads EventEngineDescription
s and passes itself as the only argument
to a static describe
method.
<?php
declare(strict_types=1);
namespace Prooph\EventEngine;
interface EventEngineDescription
{
public static function describe(EventEngine $eventEngine): void;
}
Descriptions need to be loaded before EventEngine::initialize()
is called.
In the skeleton descriptions are listed in src/Domain/DomainServices.php
and this list is read by the event engine factory method in src/ServiceFactory
:
public function eventEngine($notInitialized = false): EventEngine
{
if($notInitialized) {
$eventEngine = new EventEngine(new OpisJsonSchema());
foreach ($this->eventEngineDescriptions() as $description) {
$eventEngine->load($description);
}
return $eventEngine;
}
$this->assertContainerIsset();
return $this->makeSingleton(EventEngine::class, function () {
$eventEngine = new EventEngine(new OpisJsonSchema());
foreach ($this->eventEngineDescriptions() as $description) {
$eventEngine->load($description);
}
$eventEngine->initialize(
$this->flavour(),
$this->multiModelStore(),
$this->logEngine(),
$this->container
);
return $eventEngine;
});
}
Organising Descriptions: If you followed the tutorial, you already know that you can avoid code duplication and typing errors with a few simple tricks. Clever combinations of class and constant names can provide readable code without much effort. The skeleton ships with default Event Engine Descriptions to support you with that idea. You can find them in src/Domain/Api
Event Engine provides various registration
methods. Those methods can only be called during description phase.
See Set Up chapter for details about bootstrap phases.
Here is an overview of available methods:
<?php
declare(strict_types=1);
namespace Prooph\EventEngine;
//...
final class EventEngine implements MessageDispatcher, AggregateStateStore
{
//...
/**

*/
public function registerCommand(string $commandName, PayloadSchema $schema): self
{
//...
}
/**

*/
public function registerEvent(string $eventName, PayloadSchema $schema): self
{
//...
}
/**
* Add a query message to the system along with its payload schema (optional for queries)
*/
public function registerQuery(string $queryName, PayloadSchema $payloadSchema = null): QueryDescription
{
//...
}
/**
* Add a data type to the system along with its schema
*/
public function registerResponseType(string $nameOrImmutableRecordClass, ResponseTypeSchema $schema = null): void
{
//...
}
/**

*/
public function registerType(string $nameOrImmutableRecordClass, ResponseTypeSchema $schema = null): void
{
//...
}
/**

*

* you can use registerReponseType() and registerInputType() explicitly
*/
public function registerInputType(string $nameOrImmutableRecordClass, InputTypeSchema $schema = null): void
{
//...
}
/**

*
* You can register many preprocessors per command. Think of it like a middleware pipeline.
*

*/
public function preProcess(string $commandName, $preProcessor): self
{
//...
}
/**
* Service id or callable command controller invoked for command instead of an aggregate
*
* You can use controllers for non-aggregate business logic, migrations and more
* A command can either be handled by an aggregate or a controller.
* Event Engine takes care of this.
*
* @param string $commandName
* @param string|callable $controller
* @return EventEngine
*/
public function passToController(string $commandName, $controller): self
{
//...
}
/**
* Describe handling of a command using returned CommandProcessorDescription
*/
public function process(string $commandName): CommandProcessorDescription
{
//...
}
/**

*

* @param string | callable $listener
*/
public function on(string $eventName, $listener): self
{
//...
}
/**
* Describe a projection by using returned ProjectionDescription
*/
public function watch(Stream $stream): ProjectionDescription
{
//...
}
//...
}
Messages are like HTTP requests, but they are protocol agnostic. For HTTP requests/responses PHP-FIG has defined a standard known as PSR-7. Event Engine messages on the other hand are similar to prooph/common messages.
Like HTTP requests messages should be validated before doing anything with them. It can become a time consuming task to write validation logic for each message by hand. Hence, Event Engine has a built-in way to validate messages using a Schema (@TODO add link).
The package event-engine/php-json-schema provides a Json Schema Draft 6 compatible implementation.
You can use JsonSchema
wrapper objects. Those objects are easy to use and drastically improve
readability of the code.
Here is a command registration example:
$eventEngine->registerCommand(
self::REGISTER_USER,
JsonSchema::object([
Payload::USER_ID => Schema::userId(),
Payload::USERNAME => Schema::username(),
Payload::EMAIL => Schema::email(),
])
);
This code speaks for itself, doesn't it? Once you're used to it you can add new messages to the system in less than 30 seconds. The chapter about Json Schema (@TODO add link) covers all the details. Make sure to check it out.
A nice side effect of this approach is out-of-the-box Swagger UI support. Learn more about it in the Swagger UI (@TODO add link) chapter.
Event Engine needs to know which commands can be processed by the system. Therefor, you have to register them before defining processing logic.
Software developed with Event Engine follows a Command-Query-Responsibility-Segregation (short CQRS) approach. Commands are used to trigger state changes without returning modified state and queries are used to request current state without modifying it.
You're ask to tell Event Engine a few details about available commands. Each command should have a unique name and a payload schema. It is recommended to add a context as prefix in front of each command name. Let's take an example from the tutorial but add a context to the command name:
<?php
declare(strict_types=1);
namespace App\Api;
use Prooph\EventEngine\EventEngine;
use Prooph\EventEngine\EventEngineDescription;
use Prooph\EventEngine\JsonSchema\JsonSchema;
class Command implements EventEngineDescription
{
const CMD_CXT = 'BuildingMgmt.';
const ADD_BUILDING = self::CMD_CXT.'AddBuilding';
/**
* @param EventEngine $eventEngine
*/
public static function describe(EventEngine $eventEngine): void
{
$eventEngine->registerCommand(
Command::ADD_BUILDING,
JsonSchema::object(
[
'buildingId' => JsonSchema::uuid(),
'name' => JsonSchema::string()->withMinLength(2)
]
)
);
}
}
Event Engine makes no assumptions about the format of the name. A common approach is to use a dot notation to separate context from message name
e.g. BuildingMgmt.AddBuilding
. Using dot notation has the advantage that message broker like RabbitMQ can use it for routing.
Once Event Engine knows about a command you can register processing logic for it. Commands are processed by aggregate functions. Think of an aggregate as a process with multiple steps. Each step is triggered by a command and there is only one active step for a specific process aka. aggregate at the same time.
In Event Engine aggregate functions are stateless. You can use plain PHP functions or classes with static public methods.
Before we dive deeper into aggregate functions, let's have a look at how commands are processed.
The following gif shows a CommandProcessingDescription
.
A fluent interface mixed with clever class and constant naming + modern IDE support (PHPStorm in this case) can assist you while putting together the pieces. You need to remember less which frees your mind to reason more about the logic you're developing. This results in a higher quality business logic, written in a shorter time. Try it yourself. It's actually a lot of fun to work with Event Engine.
Keep an eye on the array callable syntax: [ShoppingCart::class, 'addItem']
. PHPStorm provides code completion for it and respects it while renaming methods and classes.
That's an awesome feature and makes the syntax save to use.
Event Engine Descriptions keep glue code outside of the core business logic. This reduces "noise" in the core and creates a central overview for navigation through the code.
Let's go through the CommandProcessingDescription step by step.
The process(string $commandName)
method takes a command name as input and starts a CommandProcessingDescription for that command.
If the command is not registered or a second processing description exists for it, Event Engine raises an exception. There can always only be one handler for a command be it an aggregate or a controller. You can only attach multiple command preprocessors to the same command.
$eventEngine->process(Command::START_SHOPPING_SESSION)
Event Engine Descriptions are really meant to be descriptive. This way you can internalize the required steps to build a CQRS / ES system. The descriptions also serve as documentation. A developer new to the system just needs to read them to get an idea of the structure and business logic.
That said, description methods are named to form a sentence. If a command should create a new aggregate use withNew(string $aggregateType)
after process()
and pass the aggregate type as an argument:
$eventEngine->process(Command::START_SHOPPING_SESSION)
->withNew(Aggregate::SHOPPING_CART)
If a new aggregate should be created, you have to tell Event Engine which command property contains the aggregate identifier. This is done
with identifiedBy(string $identifierPropName)
:
$eventEngine->process(Command::START_SHOPPING_SESSION)
->withNew(Aggregate::SHOPPING_CART)
->identifiedBy(Payload::SHOPPING_CART_ID)
You can omit identifiedBy()
in further CommandProcessingDescriptions addressing the same aggregate type as long as all commands and events always contain the same
aggregate identifier property. If this is not the case, you can also add identifiedBy()
after withExisting()
to define an alternative property name for the specific command
and related events.
If you omit identifiedBy()
at all, Event Engine uses the default property name id
and throws an exception if the command does not contain it.
Like the name suggests, withExisting(string $aggregateType)
should be used if a command addresses an existing aggregate. Event Engine will use the aggregate type and the identifier property from the
command to look up the aggregate and bring it into current state ready to handle the command.
Loading aggregates is managed by Event Engine internally. No command handlers or repositories required.
$eventEngine->process(Command::ADD_ITEM)
->withExisting(Aggregate::SHOPPING_CART)
provideContext(string $providerServiceId)
allows you to attach a context provider
to the command. It should be a service id. Event Engine pulls the context provider from the PSR-11 container.
$eventEngine->process(Command::ADD_ITEM)
->withExisting(Aggregate::SHOPPING_CART)
->provideContext(AddItemContextProvider::class)
Aggregate functions should not have any side effects. This is explained in the Functional Core chapter. But to make decisions like: "Should a command be handled or not and in what way?" - an aggregate sometimes requires information not included in its own state. This information needs to be loaded either from an external system or a database. To keep aggregates focused on the business logic, external information should be loaded beforehand. A context provider takes care of loading information. It can manage communication, deal with errors and caching. Once loaded, the information is handed over as context to the aggregate function.
While Event Engine makes no assumptions about the context format, it is highly recommended to only use immutable objects as contexts. In rare cases it might be required to pass a data resolver down to the aggregate, f.e. if the aggregate needs to decide if external data is really needed and fetching it beforehand is too costly. You can use a context object to pass dependencies into aggregate functions. But use it with care!
handle(callable $aggregateFunc)
takes a callable
as input. This is usually the aggregate function responsible for handling the command.
$eventEngine->process(Command::ADD_ITEM)
->withExisting(Aggregate::SHOPPING_CART)
->provideContext(AddItemContextProvider::class)
->handle([ShoppingCart::class, 'addItem'])
The recommended approach is to group aggregate functions in classes using static class methods. This way, you can use PHP's array callable syntax like shown in the example.
Thanks to the syntax, Event Engine can cache the Description. If you pass a Closure
to handle()
, caching won't work, because closures can't be exported. Event Engine takes
care of that limitation and throws an exception if needed.
If you use the OopFlavour
please refer to the OopFlavour tutorial part.
It explains how to describe command processing when aggregate functions are not stateless.
Tell Event Engine what possible events are yielded for a command using recordThat(string $eventName)
or one of the aliases andRecordThat(string $eventName)
or orRecordThat(string $eventName)
.
Every recordThat()
call should be followed by an apply(callable $eventApplyFunc)
call, which takes a callable
aggregate apply function for the event as argument.
$eventEngine->process(Command::ADD_ITEM)
->withExisting(Aggregate::SHOPPING_CART)
->provideContext(AddItemContextProvider::class)
->handle([ShoppingCart::class, 'addItem'])
->recordThat(Event::ITEM_ADDED)
->apply([ShoppingCart::class, 'whenItemAdded'])
->andRecordThat(Event::FREE_SHIPPING_ENABLED)
->apply([ShoppingCart::class, 'whenFreeShippingEnabled']);
The aggregate handle function doesn't need to yield all specified events each time and the recordThat aliases are only defined for better readability. The important thing is, that Event Engine knows all events and their corresponding apply functions.
storeStateIn(string $collection)
tells Event Engine to store the aggregate state in the specified document store collection.
This description only takes effect when using a Multi-Model-Store (@TODO add link). It can only be used when describing
command processing for a NEW aggregate:
$eventEngine->process(Command::START_SHOPPING_SESSION)
->withNew(Aggregate::SHOPPING_CART)
->identifiedBy(Payload::SHOPPING_CART_ID)
->storeStateIn('shopping_carts')
// ...
If you don't specify a collection, Event Engine defaults to:
$aggregateCollection = AggregateProjector::aggregateCollectionName(
'0.1.0', // <- Default projection version
Aggregate::SHOPPING_CART // <- Aggregate type of command processing description
);
echo $aggregateCollection; // em_ds_shopping_cart_0_1_0
Make sure to create the collection upfront! It is NOT created automatically by Event Engine. The tutorial provides some guidance.
By default, Event Engine writes all events into its WriteModelStream
. If you wish to write events for a certain
aggregate type into a separate stream, you can use storeEventsIn(string $streamName)
. Like storeStateIn()
, you can
define an alternative stream only when describing command processing for a new aggregate.
$eventEngine->process(Command::START_SHOPPING_SESSION)
->withNew(Aggregate::SHOPPING_CART)
->identifiedBy(Payload::SHOPPING_CART_ID)
->storeStateIn('shopping_carts')
->storeEventsIn('shopping_cart_history')
// ...
You need to take care of creating alternative event streams. The skeleton includes an example script. Just change the stream name.
If you don't want to handle a command with an aggregate, you can pass it to a command controller (@TODO add link) instead:
$eventEngine->passToController(MyCommandController::class);
The controller instance is pulled from the PSR-11 container using the service id handed over to passToController()
.
A command can either be handled by a controller or an aggregate, but not both. A command always has one handler only.
Event registration works similar to command registration described above. Before you can reference events in command processing descriptions they need to be known by Event Engine. This mechanism protects you from silly mistakes like misspelling an event name or forgetting to define a schema for it.
$eventEngine->registerEvent(
self::USER_REGISTERED,
JsonSchema::object([
Payload::USER_ID => Schema::userId(),
Payload::USERNAME => Schema::username(),
Payload::EMAIL => Schema::email(),
])
);
One of the strengths of Event Sourcing is the ability to automate processes using an Event-Driven approach. This means, that follow up actions can be triggered when certain events occur. Those automatic triggers are called process managers. Here is an example how you attach a process manager to an event:
$eventEngine->on(Event::USER_REGISTERED, SendWelcomeEmail::class);
If a process manager has dependencies, pass a service id to $eventEngine->on()
so that it is pulled from the PSR-11 container.
A stateless process manager that listens on an event to dispatch a new command, can be provided as a callable
. It's recommended to use the array callable syntax like
discussed for aggregate functions.
Let's look at an example:
Whenever an order was placed the system should generate an invoice.
final class GenerateInvoiceTrigger
{
public static function onOrderPlaced(Message $orderPlaced): array
{
return [
Command::GENERATE_INVOICE,
[
Payload::ORDER_ID => $orderPlaced->get(Payload::ORDER_ID)
]
];
}
}
A process manager can return a command using the "short message syntax" of Event Engine. The command is automatically dispatched by Event Engine. The only thing we need to do is to attach the process manager function to the correct event:
$eventEngine->on(Event::ORDER_PLACED, [GenerateInvoiceTrigger::class, 'onOrderPlaced']);

About Me
I am a Full Stack and Back End developer based out of Fredricksbug, Virginia. Currently I have obtained my Certificate for completing the rigours coding and web design course at George Washington University in Arlington, Virginia. Due to my self driven nature and high level of motivation I was able to balance being an essential worker at whole foods and academic studies. Being versed in HTML,CSS,JAVASCRIPT, BULMA, JQUERY, NODE.JS, MYSQL I was able to play a pivotal role in the development of an online game tournament tracker. The team I worked on built it to track multiple games across different platforms. I’m eager to use my ingenuity and dexterity to provide unique user experiences.

Springboks' World Cup winner Brits calls time on career
South Africa hooker Schalk Brits announced his retirement from all forms of rugby on Wednesday, the second time the 38-year-old has brought down the curtain on his career.
CAPE TOWN: South Africa hooker Schalk Brits announced his retirement from all forms of rugby on Wednesday, the second time the 38-year-old has brought down the curtain on his career.
Brits retired in May 2018 after leaving Saracens but was lured back by Springboks coach Rassie Erasmus and helped them lift the Rugby World Cup in Japan this month, ending his international career with 15 caps over an 11-year period.

THE STUPIDS A film review by Michael John Legeros Copyright 1996 Michael John Legeros
(New Line) Directed by John Landis Written by Brent Forrester, based on characters created by Harry Allard and James Marshall Cast Tom Arnold, Jessica Lundy, Bug Hall, Alex McKenna, Mark Metcalf, Matt Keeslar, Frankie Faison, Christopher Lee, Bob Keeshan MPAA Rating "PG" Running Time 94 minutes Reviewed at The Carmike 7, Raleigh, NC (30AUG96)
==
Director John Landis is back at it, still light years away from the comic masterpieces of NATIONAL LAMPOON'S ANIMAL HOUSE, THE BLUES BROTHERS, AN AMERICAN WEREWOLF IN LONDON, and TRADING PLACES, but obviously having a high time adapting Harry Allard and James Marshall's series of children's books. The central joke here is that Stanley Stupid and his family take *everything* at face value. When their trash is missing from the curb cans, they think somebody stole it. When Dad (Tom Arnold) discovers the city dump, he thinks he's uncovered the crime of the century. When the kids (Bug Hall and Alex McKenna) can't find their father anywhere in the house, they think he's been kidnapped. And so on.
 The cast has enormous enthusiasm and the costumes (and some sets) are relentlessly sunny. (Kids would like the latter, if this were a movie for kids. I'm not sure if it is.) The cheerfully chaotic plot is one of the most unpredictable in recent memory, adding arms dealers, space aliens, and a postal conspiracy into the mix. Film fans will also enjoy the director's trademark in-jokes, from "see you next Wednesday" to the casting of prominent directors in cameo roles. (That's David Cronenberg as Stanley's old boss and Robert Wise as the neighbor. You find the rest.)
What's missing is a better attention to detail. Though the sloppy editing is entirely annoying-- *must* they cut away in the middle of a musical number?-- the most glaring gaffe is the film's failure to adhere to a consistent set of rules regarding exactly how this Stupid universe is supposed to behave. Other people, places, and things are allowed to act as goofy as the title characters do and that's a mistake.  This is one movie that might be funnier if it tried to be less funny. Trust in the Lloyd.
Grade: C+

Class: Rails::PluginBuilder
| Relationships & Source Files | |
| Inherits: | Object |
| Defined in: | railties/lib/rails/generators/rails/plugin/plugin_generator.rb |
Overview
The plugin builder allows you to override elements of the plugin generator without being forced to reverse the operations of the default generator.
This allows you to override entire operations, like the creation of the Gemfile, README, or JavaScript files, without needing to know exactly what those operations do so you can create another template action.

The characters are all imps ( tiny mischievous devils) who were all representing the vices of mankind also known as the seven deadly sins. With no humans to torment and influence, they decide to find positive attributes to their vices. The build villages that cater to their ideas and realized that the other villages not only have different views, but resources that can help them. No other vice is stronger than the other, so they begin to trade with one another to avoid conflict and learn from one another. They begin to diversify their own villages, realizing that with different influences and points of views, their own lives can grow. However, some richer imps like greed and gluttony tend to take advantage of the poorer imps, like sloth and wrath imps, who live in less ideal places, by pushing them out by hoarding resources and isolating the imps in certain villages, like pride, who do not wish to interact with the other imps due to their drastic cultural difference and beliefs.
What are Imps?
Do The Seven Deadly sins have positive atributes?

WATCH: General Chiwenga lands in Harare; welcomed by China officials
by Mandla NdlovuVice President Constantino Chiwenga arrived in Harare on Saturday morning where he was received by the Chinese Deputy Ambassador to Zimbabwe and close members of his family.
The former Zimbabwe strongman has been on a medical pilgrimage to China for the past three months after suffering multiple organ failure.
There have been fears that Chiwenga is plotting a coup against President Emmerson Mnangagwa with China.
There was no government official of ZANU PF official to receive the former Army boss.

CAPGET
Section: Linux Programmer's Manual (2)
Updated: 2013-03-11
Index
Return to Main Contents
NAME
capget, capset - set/get capabilities of thread(s)
SYNOPSIS
#include <sys/capability.h>
int capget(cap_user_header_t hdrp, cap_user_data_t datap);
int capset(cap_user_header_t hdrp, const cap_user_data_t datap);
DESCRIPTION
As of Linux 2.2,
the power of the superuser (root) has been partitioned into
a set of discrete capabilities.
Each thread has a set of effective capabilities identifying
which capabilities (if any) it may currently exercise.
Each thread also has a set of inheritable capabilities that may be
passed through an
execve(2)
call, and a set of permitted capabilities
that it can make effective or inheritable.
These two system calls are the raw kernel interface for getting and
setting thread capabilities.
Not only are these system calls specific to Linux,
but the kernel API is likely to change and use of
these system calls (in particular the format of the
cap_user_*_t
types) is subject to extension with each kernel revision,
but old programs will keep working.
The portable interfaces are
cap_set_proc(3)
and
cap_get_proc(3);
if possible, you should use those interfaces in applications.
If you wish to use the Linux extensions in applications, you should
use the easier-to-use interfaces
capsetp(3)
and
capgetp(3).
Current details
Now that you have been warned, some current kernel details.
The structures are defined as follows.
#define _LINUX_CAPABILITY_VERSION_1 0x19980330
#define _LINUX_CAPABILITY_U32S_1 1
#define _LINUX_CAPABILITY_VERSION_2 0x20071026
#define _LINUX_CAPABILITY_U32S_2 2
typedef struct __user_cap_header_struct {
__u32 version;
int pid;
} *cap_user_header_t;
typedef struct __user_cap_data_struct {
__u32 effective;
__u32 permitted;
__u32 inheritable;
} *cap_user_data_t;
The
effective,
permitted,
and
inheritable
fields are bit masks of the capabilities defined in
capabilities(7).
Note the
CAP_*
values are bit indexes and need to be bit-shifted before ORing into
the bit fields.
To define the structures for passing to the system call you have to use the
struct __user_cap_header_struct
and
struct __user_cap_data_struct
names because the typedefs are only pointers.
Kernels prior to 2.6.25 prefer
32-bit capabilities with version
_LINUX_CAPABILITY_VERSION_1,
and kernels 2.6.25+ prefer 64-bit capabilities with version
_LINUX_CAPABILITY_VERSION_2.
Note, 64-bit capabilities use
datap[0]
and
datap[1],
whereas 32-bit capabilities use only
datap[0].
Another change affecting the behavior of these system calls is kernel
support for file capabilities (VFS capability support).
This support is currently a compile time option (added in kernel 2.6.24).
For
capget()
calls, one can probe the capabilities of any process by specifying its
process ID with the
hdrp->pid
field value.
With VFS capability support
VFS Capability support creates a file-attribute method for adding
capabilities to privileged executables.
This privilege model obsoletes kernel support for one process
asynchronously setting the capabilities of another.
That is, with VFS support, for
capset()
calls the only permitted values for
hdrp->pid
are 0 or
getpid(2),
which are equivalent.
Without VFS capability support
When the kernel does not support VFS capabilities,
capset()
calls can operate on the capabilities of the thread specified by the
pid
field of
hdrp
when that is nonzero, or on the capabilities of the calling thread if
pid
is 0.
If
pid
refers to a single-threaded process, then
pid
can be specified as a traditional process ID;
operating on a thread of a multithreaded process requires a thread ID
of the type returned by
gettid(2).
For
capset(),
pid
can also be: -1, meaning perform the change on all threads except the
caller and
init(8);
or a value less than -1, in which case the change is applied
to all members of the process group whose ID is -pid.
For details on the data, see
capabilities(7).
RETURN VALUE
On success, zero is returned.
On error, -1 is returned, and
errno
is set appropriately.
The calls will fail with the error
EINVAL,
and set the
version
field of
hdrp
to the kernel preferred value of
_LINUX_CAPABILITY_VERSION_?
when an unsupported
version
value is specified.
In this way, one can probe what the current
preferred capability revision is.
ERRORS
- EFAULT
-
Bad memory address.
hdrp
must not be NULL.
datap
may be NULL only when the user is trying to determine the preferred
capability version format supported by the kernel.
- EINVAL
-
One of the arguments was invalid.
- EPERM
-
An attempt was made to add a capability to the Permitted set, or to set
a capability in the Effective or Inheritable sets that is not in the
Permitted set.
- EPERM
-
The caller attempted to use
capset()
to modify the capabilities of a thread other than itself,
but lacked sufficient privilege.
For kernels supporting VFS
capabilities, this is never permitted.
For kernels lacking VFS
support, the
CAP_SETPCAP
capability is required.
(A bug in kernels before 2.6.11 meant that this error could also
occur if a thread without this capability tried to change its
own capabilities by specifying the
pid
field as a nonzero value (i.e., the value returned by
getpid(2))
instead of 0.)
- ESRCH
-
No such thread.
CONFORMING TO
These system calls are Linux-specific.

functions is provided by the

24 March 2006
The Ministry of Health in China has confirmed the country’s 16th case of human infection with the H5N1 avian influenza virus. The case, which was fatal, occurred in a 29-year-old female migrant worker. She was hospitalized in Shanghai on 15 March with symptoms of pneumonia and died on 21 March.
This is the first case reported in Shanghai. Her source of infection is under investigation. No poultry outbreaks have been reported in the Shanghai area since February 2004.
According to Chinese authorities, the woman’s close contacts have been placed under medical observation.
To date, China has reported 16 cases of H5N1 infection, of which 11 have been fatal.

You properly know the The Curation and Engagement Leagues from abh12345. I plan to do something similar with the following differences:
- Programmed voting allowed
- Leasing or powering down/up of Steem Power is allowed
After some feedback, I decided that there will be different classes based on effective SP and used upvote weight.
I’m using my python library for steem in order to calculate the following quotient:
collected curation rewards within a week divided by effective Steem Power and multiplied by 1000
Collected curation rewards are determined by curation_reward
virtual account operations.
I will calculate the effective Steem power value for each received curation reward. Therefore, change in effective Steem Power over the week does not matter.
To enter the contest, please write a comment with add me
. A comment remove me
will exclude an account from the contest. I will automatically scan the comments for building a participation list.
The following image shows the curation over time for my account:
Can you beat my 2.05 SP per week and 1k Steem power? If you want to know, then enter the contest by writing a comment with add me
!
The first contest will start next Sunday/Monday.

What a journey it has been! I am almost afraid to part from this experience because it represents so much of the unknown when it comes to bootcamp. The core part of this process, made me think of myself as objectively as possible and I found myself questioning ideas that I once thought true about myself. I even try and describe simple things like riding a lift in the terms of a function. I extremely grateful for everything I have learnt and humbled by this experience.
Aside from all the learning, it was wonderful to get to know the people in my cohort and the Hihi cohort during the Foundations sprints. They have been absolutely amazing to work with and I could not have grown as much as I did if I did not have them or my facilitator around to guide me through the process.
What are three new things you have learned about yourself and your ego as a result of the core learning?
I didn't know this about myself but I find that I am quite a literal person. I do go off tangent like everyone else but one thing I require is actual answers. I don't understand abstract concepts or ideas that are not grounded. I have an issue with understanding people who are not clear and concise about what they intend. The listening and looping excercise was handy with helping me identify this together with speaking to members of my cohort, though my partner for this excercise was as literal as I was, I began to think more about some people who I felt I never understood. I now am completely self-aware of my trait and have a strategy to deal with this going forward.
In the identities exploration excercise, I disovered that I have two distinct personalities, an introvert and an extrovert (I'm and ambivert!). The introvert liked to think about things and work through the problems in her head. The extrovert allowed me to reach out to others and discuss things when I didn't understand them.
My final discovery was that I always trying to compare myself to other people.Core helped me identify that I placed my sense of self worth in others. I discovered in Sprint 1 that people have different ways of processing information and work at different speeds and this has nothing to do with how great your product will be. I learnt was that I would get things when I would get them and until I did, I had to keep practicing!
What are the role of values, empathy and self awareness in learning and programming?
Programming is all about working with other people for other people. Since we all are different when there is a lack of effective communication, conflict could arise within a teams dynamic. Values, empathy and self awareness play a role in bridging the gaps in communication within groups of people.
What has surprised you the most about the core learning?
We assume that core is relatively simple however in reality it is difficult to dig deep and articulate how we process ideas, views and situations. In particular, core learning helped me feel more at home with myself and understanding that it is all about celebrating the small successes.
What were the most challenging aspects of the core learning?
The most challenging part of core learning is being honest about who you are and how you are feeling in your reflections. It is diffiult to write about yourself and have others read your thoughts and feelings especially when you are confronting or addressing attributes that you are completely unaware of. Through this process I have come to acknowledge my own areas of weakness and get over prejudices when it came to the learning process.
Why do you think we, a programming school, are spending so much time focusing on core learning in a web development bootcamp course?
When you are in a high pressure situation where you have to work with other people, we should be able to learn the techniques required to deal with conflict, disruption and varring perspectives. At the same time, we need to learn how to celebrate every person's victories as a team. One of my favourite saying by Paulo Coelho states that “Happiness is something that multiplies when it is divided.”
Does the time you spent studying core learning here feel like a waste of time? Should you have just used that time to practicing programming instead? Justify your answer.
No, I don't think it is a waste of time and I do want to keep practicing programming, but not at the cost of what I have learnt as part of core. Doing the blogs and completing my reflections, made me feel heard and understood. I am here to learn about development but to learn something in a short frame of time is about having resiliance and the core learning is there to help me build it and continues to do so.
If anyone would keep going at a problem because they felt they needed to get it as soon as they learnt about it, I would now turn around and tell them I felt the same way but now this has all changed for me. We are learning a new language, we can't do that without using a dictionary. You can't go to Japan and know how to speak Japanese on the first try, you keep referring to the dictionary and pick it up as you go. You will eventually become fluent because you pratice it everyday and perhaps one day you will not need a dictionary.
