From 33d899d5faebdcebd917281809b7f7be5c6f3615 Mon Sep 17 00:00:00 2001 From: Wouter Wolters Date: Sat, 14 Nov 2026 17:10:47 +0100 Subject: [PATCH] [TASK] Reuse sequence metadata in database snapshots Record auto-increment column names during snapshot export and pass them to the existing sequence reset helper when restoring rows. Skip sequence resets for tables without an auto-increment column. This avoids repeated PostgreSQL catalog queries and restores generated IDs correctly for quoted mixed-case columns. Add functional coverage for ordinary and custom ID columns, repeated restores and non-sequence tables. A local PostgreSQL 17 benchmark of SlugLinkGeneratorTest drops from 46.93 s to 42.37 s with the same 194 tests and 202 assertions. The number of sequence catalog lookups drops from 2,123 to zero. WIP: prepared for CI validation. --- .../Snapshot/DatabaseAccessor.php | 21 +++-- .../DatabaseAccessorSequenceTest.php | 92 +++++++++++++++++++ 2 files changed, 107 insertions(+), 6 deletions(-) create mode 100644 Tests/Functional/DatabaseAccessorSequenceTest.php diff --git a/Classes/Core/Functional/Framework/DataHandling/Snapshot/DatabaseAccessor.php b/Classes/Core/Functional/Framework/DataHandling/Snapshot/DatabaseAccessor.php index f6729e85..97c57147 100644 --- a/Classes/Core/Functional/Framework/DataHandling/Snapshot/DatabaseAccessor.php +++ b/Classes/Core/Functional/Framework/DataHandling/Snapshot/DatabaseAccessor.php @@ -53,8 +53,16 @@ public function export(): array if (empty($tableExport)) { continue; } + $autoIncrementColumnName = null; + foreach ($table->getColumns() as $column) { + if ($column->getAutoincrement()) { + $autoIncrementColumnName = $column->getName(); + break; + } + } $export[] = [ 'tableName' => $tableName, + 'autoIncrementColumnName' => $autoIncrementColumnName, 'columns' => $this->prepareColumns( array_keys($tableExport[0]), $table @@ -74,7 +82,8 @@ public function import(array $import): void $this->importTable( $tableImport['tableName'] ??
