From 05415aa9e088e0ec330709599eefb83722456a2a Mon Sep 17 00:00:00 2001 From: Matan Baruch Date: Thu, 13 Aug 2026 12:15:23 +0300 Subject: [PATCH 1/6] Bug#102586 ON DELETE CASCADE breaks with RBR and multiple-table DELETE A multi-table DELETE that names both a foreign key parent table and a child table with a cascading delete rule breaks row-based replication. The replica applier stops with ER_KEY_NOT_FOUND. The parent row is deleted while the join is still scanning, so the cascade removes the child rows and logs row events for them. The statement logs row events for the child rows it deletes itself as well. On the replica the parent delete is applied first, its own cascade removes the child rows, and the logged child events then cannot find them. Exclude a delete target from immediate deletion when deleting from it cascades to another table in the same query, which defers the delete until the join has finished. The check is added to both the classic optimizer (GetImmediateDeleteTables) and the hypergraph optimizer (IsImmediateDeleteCandidate). Only ON DELETE CASCADE is considered. ON DELETE SET NULL updates the child rows rather than deleting them, so they stay findable for the logged events and replicate correctly. Deferring those deletes as well would change which rows the statement removes. This is the approach Zsolt Parragi contributed on Bug#80821 in 2019, adapted to the current code: get_cascade_foreign_key_table_list() no longer exists, so the cascade dependency is resolved from TABLE_SHARE::foreign_key_parent instead. --- .../rpl_multi_table_delete_fk_cascade.result | 53 +++++++++++ .../t/rpl_multi_table_delete_fk_cascade.test | 89 +++++++++++++++++++ sql/join_optimizer/join_optimizer.cc | 7 ++ sql/sql_base.cc | 47 ++++++++++ sql/sql_base.h | 2 + sql/sql_delete.cc | 7 +- 6 files changed, 203 insertions(+), 2 deletions(-) create mode 100644 mysql-test/suite/rpl/r/rpl_multi_table_delete_fk_cascade.result create mode 100644 mysql-test/suite/rpl/t/rpl_multi_table_delete_fk_cascade.test diff --git a/mysql-test/suite/rpl/r/rpl_multi_table_delete_fk_cascade.result b/mysql-test/suite/rpl/r/rpl_multi_table_delete_fk_cascade.result new file mode 100644 index 000000000000..0fd33bce8e96 --- /dev/null +++ b/mysql-test/suite/rpl/r/rpl_multi_table_delete_fk_cascade.result @@ -0,0 +1,53 @@ +include/rpl/init_source_replica.inc +Warnings: +Note #### Sending passwords in plain text without SSL/TLS is extremely insecure. +Note #### Storing MySQL user name or password information in the connection metadata repository is not secure and is therefore not recommended.

Replace the custom review client with the pinned OpenAI Codex Action, bound its input to a validated PR diff, pin third-party actions, and add dependency maintenance for GitHub Actions. Retry a failed or empty Codex review once after a delay with a configurable fallback model while preserving the same read-only isolation boundary and structured output contract. Publish structured Codex findings as one commit-bound GitHub review. Validate each file and right-side line range against the current diff, keep unanchored findings in the summary, prevent duplicate reviews, and revalidate both reviewed revisions before posting. Warm trusted Boost and ccache entries, align the MTR compiler cache with the GCC build, shard MTR suites across runners, run tests in parallel with bounded retries, and retain diagnostics. Safely reset head-scoped CI state, standardize labels, and remove the obsolete OCA checkbox. Require both the OCA Verified label and a current trusted approval before adding Integrate. Revalidate both conditions around label publication and remove Integrate if either condition no longer holds. Temporarily disable parallel-run failures tracked by Bug#39882117 and restore the required restart and expected output for the buffer-pool-load MTR.

ON DELETE SET NULL gives wrong results the same way CASCADE does, since the action rewrites child rows the join has not read yet. - Follow referential actions transitively. A delete cascading from t1 into t2 can trigger t2's own actions into t3, so t3 being in the query makes immediate deletes from t1 unsafe even when t2 is not in the query. Whether a table's children are affected through their delete rule or their update rule depends on whether the action deletes or updates that table's rows. The walk finds intermediate tables among the open tables, which prelocking guarantees to include every table reachable through referential actions. - Apply the same check to multi-table UPDATE, in safe_update_on_fly() for the traditional optimizer and IsImmediateUpdateCandidate() for the hypergraph optimizer. - Replace the replication test with a main-suite test showing wrong results on a single server, using the reviewer's reproductions, plus an indirect-cascade case and two multi-table UPDATE cases. --- .../r/foreign_key_multi_table_dml.result | 225 ++++++++++++++++++ .../rpl_multi_table_delete_fk_cascade.result | 53 ----- .../t/rpl_multi_table_delete_fk_cascade.test | 89 ------- mysql-test/t/foreign_key_multi_table_dml.test | 189 +++++++++++++++ sql/join_optimizer/join_optimizer.cc | 11 +- sql/sql_base.cc | 130 +++++++--- sql/sql_base.h | 5 +- sql/sql_delete.cc | 3 +- sql/sql_update.cc | 10 +- 9 files changed, 537 insertions(+), 178 deletions(-) create mode 100644 mysql-test/r/foreign_key_multi_table_dml.result delete mode 100644 mysql-test/suite/rpl/r/rpl_multi_table_delete_fk_cascade.result delete mode 100644 mysql-test/suite/rpl/t/rpl_multi_table_delete_fk_cascade.test create mode 100644 mysql-test/t/foreign_key_multi_table_dml.test diff --git a/mysql-test/r/foreign_key_multi_table_dml.result b/mysql-test/r/foreign_key_multi_table_dml.result new file mode 100644 index 000000000000..a3e7f0e817c0 --- /dev/null +++ b/mysql-test/r/foreign_key_multi_table_dml.result @@ -0,0 +1,225 @@ +# +# Multi-table DELETE with ON DELETE CASCADE +# +CREATE TABLE t1(id INT PRIMARY KEY, i INT);

With engine-managed referential actions (innodb_native_foreign_keys) prelocking does not add child tables, so the walk cannot continue; buffer the modification in that case, since the engine-internal action poses the same hazard. - Track visited tables per (table, deleted-vs-updated) state. The two states can lead to different descendants, so a table reached along both a delete path and an update path in a diamond-shaped foreign key graph must be walked once per state. Keying on the table alone could skip the state that reaches a queried table and incorrectly allow immediate modification. - Make the multi-table UPDATE test cases update a referenced secondary unique key instead of the clustered primary key. Updating the primary key already made the traditional optimizer buffer the update, so the old shape did not exercise the new check. --- .../r/foreign_key_multi_table_dml.result | 157 +++++++++++------- mysql-test/t/foreign_key_multi_table_dml.test | 112 ++++++++++--- sql/sql_base.cc | 30 ++-- 3 files changed, 202 insertions(+), 97 deletions(-) diff --git a/mysql-test/r/foreign_key_multi_table_dml.result b/mysql-test/r/foreign_key_multi_table_dml.result index a3e7f0e817c0..d62bf0cd1897 100644 --- a/mysql-test/r/foreign_key_multi_table_dml.result +++ b/mysql-test/r/foreign_key_multi_table_dml.result @@ -110,36 +110,79 @@ id mid_id 22 NULL DROP TABLE t3, t_mid, t1;
