roundingwell 最重要的系统之一是评估引擎,或者我们通常所说的“评估”。该系统负责处理特定于客户的配置事件侦听器,这使我们能够为每个组织提供高度独特的用户体验。不用说,这个系统对我们的应用程序非常重要,并且能够准确地知道它做了什么、或将要做什么,对于给定的事件至关重要。
今天,我正在努力将我们的一位客户从一些旧事件转换为新事件,并且需要确保其中一个步骤能够正确处理事件。我们有很多关于评估的日志记录,我知道我需要的信息就在日志中。但拥有大量日志记录的问题是,有很多日志。另外,我只需要运行每个触发器的第一部分来验证迁移是否有效。
我心想,“如果我们能为评估引擎提供一个类似 xdebug 的单步调试器,这不是很聪明吗?我知道 symfony console 拥有我需要的所有功能……”
而这正是我所做的。因为我们的应用程序是完全依赖注入的,所以我能够创建一个新类来包装 stepfactory,它负责读取配置并创建构成评估的“步骤”。
use roundingwell/framework/debugvar;
use runtimeexception;
use symfony/component/console/style/symfonystyle;
readonly class stepfactorywithconsoleconfirmation implements stepfactory
{
public function __construct(
private stepfactory $stepfactory,
private symfonystyle $style,
private bool $confirmcreatedstep = true,
private bool $showcreatedstep = true,
private bool $showstepdefinition = false,
) {
}
public function create(object $subject, stepdefinition $definition): step
{
if ($this->showstepdefinition) {
$debug = new debugvar($definition->parameters);
$this->style->info(
message: name with parameters:
$debug
text,
);
}
$step = $this->stepfactory->create($subject, $definition);
if ($this->showcreatedstep) {
$debug = new debugvar($step);
$this->style->info(
message: name created as:
$debug
text,
);
}
if ($this->confirmcreatedstep && ! $this->style->confirm(question: "continue with evaluation?")) {
throw new runtimeexception(
message: "evaluation aborted at step {$definition->name}",
);
}
return $step;
}
}

并且,通过我的控制台命令中的一些容器操作,我们有一个交互式评估调试器:
use DI/Container;
use RoundingWell/Common/Command/CommandBus;
use RoundingWell/Common/Command/CommandBusComposed;
use RoundingWell/Common/Command/Middleware/LoggingMiddleware;
use RoundingWell/Evaluation/Command/EvaluateEvent;
use RoundingWell/Evaluation/Command/EvaluateEventHandler;
use RoundingWell/Evaluation/Step/StepFactory;
use RoundingWell/Evaluation/Step/StepFactoryWithConsoleConfirmation;
use Symfony/Component/Console/Style/SymfonyStyle;
readonly class EvaluationDebug
{
public function __construct(
private Container $container,
) {
}
public function __invoke(
SymfonyStyle $symfonyStyle,
string $eventType,
string $eventId,
string|null $evaluationId = null,
): void {
// The command bus MUST ONLY log executed commands.
$commandBus = new CommandBusComposed(
$this->container->get(LoggingMiddleware::class),
);
// The step factory MUST be wrapped to step through the evaluation.
$stepFactory = new StepFactoryWithConsoleConfirmation(
stepFactory: $this->container->get(StepFactory::class),
style: $symfonyStyle,
);
$this->container->set(CommandBus::class, $commandBus);
$this->container->set(StepFactory::class, $stepFactory);
$command = new EvaluateEvent(
eventClass: $eventType,
eventId: $eventId,
evaluationId: $evaluationId,
);
$this->container->get(EvaluateEventHandler::class)->handle($command);
$symfonyStyle->success('Evaluation complete');
}
}

今天就这样!
