From b4bbe5f8328570da041aac6ed6a2dc699c68c57b Mon Sep 17 00:00:00 2001 From: ck Date: Tue, 24 Mar 2026 15:50:54 +0800 Subject: [PATCH] feat: implement event parser optimization (Issue #40) - EventRecord parsing with phase support - Event indexing for fast lookups - Error event detection - Phase enum (ApplyExtrinsic/Finalization/Initialization) Components: - Phase: Execution phase enum - Event: Event data model - EventRecord: Event with phase and topics - EventParser: SCALE parser for events - EventIndex: Indexing utility for fast lookups - ErrorEventDetector: Error event detection Features: - Parse Vec from SCALE - Phase-based filtering - Event lookup by name/pallet/extrinsic - Error event detection (ExtrinsicFailed, etc) - Topic parsing Tests: - Unit tests for all components - Phase tests - EventRecord tests - Parser tests - Index tests - Error detector tests Closes #40 --- src/Event/ErrorEventDetector.php | 129 ++++++++++ src/Event/Event.php | 64 +++++ src/Event/EventIndex.php | 170 ++++++++++++ src/Event/EventParser.php | 234 +++++++++++++++++ src/Event/EventRecord.php | 82 ++++++ src/Event/Phase.php | 40 +++ tests/Event/EventTest.php | 427 +++++++++++++++++++++++++++++++ 7 files changed, 1146 insertions(+) create mode 100644 src/Event/ErrorEventDetector.php create mode 100644 src/Event/Event.php create mode 100644 src/Event/EventIndex.php create mode 100644 src/Event/EventParser.php create mode 100644 src/Event/EventRecord.php create mode 100644 src/Event/Phase.php create mode 100644 tests/Event/EventTest.php diff --git a/src/Event/ErrorEventDetector.php b/src/Event/ErrorEventDetector.php new file mode 100644 index 0000000..cdcaae5 --- /dev/null +++ b/src/Event/ErrorEventDetector.php @@ -0,0 +1,129 @@ + 'System', 'name' => 'ExtrinsicFailed'], + ['pallet' => 'System', 'name' => 'CodeNotFound'], + ['pallet' => 'System', 'name' => 'InvalidSpecName'], + ['pallet' => 'System', 'name' => 'SpecVersionNeeded'], + ]; + + /** + * @var array Events + */ + private array $events; + + /** + * Create an error detector from event records. + * + * @param array $events Event records + */ + public function __construct(array $events) + { + $this->events = $events; + } + + /** + * Check if there are any error events. + */ + public function hasErrors(): bool + { + foreach (self::ERROR_EVENTS as $pattern) { + foreach ($this->events as $event) { + if ($event->event->pallet === $pattern['pallet'] + && $event->event->name === $pattern['name']) { + return true; + } + } + } + return false; + } + + /** + * Get all error events. + * + * @return array Error events + */ + public function getErrors(): array + { + $errors = []; + foreach (self::ERROR_EVENTS as $pattern) { + foreach ($this->events as $event) { + if ($event->event->pallet === $pattern['pallet'] + && $event->event->name === $pattern['name']) { + $errors[] = $event; + } + } + } + return $errors; + } + + /** + * Check if a specific extrinsic failed. + * + * @param int $extrinsicIndex Extrinsic index + */ + public function extrinsicFailed(int $extrinsicIndex): bool + { + foreach ($this->events as $event) { + if ($event->event->pallet === 'System' + && $event->event->name === 'ExtrinsicFailed' + && $event->getExtrinsicIndex() === $extrinsicIndex) { + return true; + } + } + return false; + } + + /** + * Get the first ExtrinsicFailed event for an extrinsic. + * + * @param int $extrinsicIndex Extrinsic index + * @return EventRecord|null The error event or null + */ + public function getExtrinsicError(int $extrinsicIndex): ?EventRecord + { + foreach ($this->events as $event) { + if ($event->event->pallet === 'System' + && $event->event->name === 'ExtrinsicFailed' + && $event->getExtrinsicIndex() === $extrinsicIndex) { + return $event; + } + } + return null; + } + + /** + * Get error summary for a block. + * + * @return array Map of error identifiers to counts + */ + public function getErrorSummary(): array + { + $summary = []; + foreach ($this->events as $event) { + $id = $event->event->getIdentifier(); + foreach (self::ERROR_EVENTS as $pattern) { + if ($event->event->pallet === $pattern['pallet'] + && $event->event->name === $pattern['name']) { + if (!isset($summary[$id])) { + $summary[$id] = 0; + } + $summary[$id]++; + } + } + } + return $summary; + } +} diff --git a/src/Event/Event.php b/src/Event/Event.php new file mode 100644 index 0000000..e61ce5b --- /dev/null +++ b/src/Event/Event.php @@ -0,0 +1,64 @@ +pallet}.{$this->name}"; + } + + /** + * Get the event data by field name. + */ + public function getField(string $name): mixed + { + return $this->data[$name] ??
