From 43233fe469fd85d7c64978f01ed68de3288d43cc Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Vicen=C8=9Biu=20Ciorbaru?= Date: Fri, 10 Jan 2025 10:08:24 +0200 Subject: [PATCH 001/118] Fix -DBUILD_CONFIG=mysql_release to keep standard cmake flags -DCMAKE_BUILD_TYPE=xxx sets some C compiler flags according to the build type. -DBUILD_CONFIG was completely overwriting them in some compiler / arch combinations and not in others. Make it consistently "append-only", not overwrite. Also, enforce the same set of flags for Release and RelWithDebInfo. This reverts ff1f611a0d84b84a06b100a3b6901fc6d8957ff5 as it is no longer necessary. Avoid assert() By default, CMAKE_BUILD_TYPE RelWithDebInfo or Release implies -DNDEBUG, which disables the assert() macro. MariaDB is deviating from that. Let us be explicit to use assert() only in debug builds. --- .../build_configurations/mysql_release.cmake | 104 ++++++++++++------ storage/innobase/include/trx0trx.h | 8 +- 2 files changed, 73 insertions(+), 39 deletions(-) diff --git a/cmake/build_configurations/mysql_release.cmake b/cmake/build_configurations/mysql_release.cmake index 096b0afd6aa..8a34b0a6071 100644 --- a/cmake/build_configurations/mysql_release.cmake +++ b/cmake/build_configurations/mysql_release.cmake @@ -187,30 +187,40 @@ IF(UNIX) # Default GCC flags IF(CMAKE_COMPILER_IS_GNUCC) SET(COMMON_C_FLAGS "-g -fno-omit-frame-pointer -fno-strict-aliasing -Wno-uninitialized") -

With the regression, mariadb-binlog cannot process multiple log files when --stop-datetime is specified. The change is to keep recording timestamp of last processed event, and after all log files are processed, if the last recorded timestamp has not reached specified --stop-datetime, it will emit a warning. This applies when processing local log files, or log files from remote servers.

Because of the way myisam is .c files the function prototype is mismatched. As Marko pointed out the MYSQL_THD is declared as void * in C. Thanks Jimmy Hรบ for noting that struct THD is the equalivalant in C to the class THD. The C NULL was also different to the C++ nullptr. Corrected the definations of MYSQL_THD and DEBUG_SYNC_C to be C and C++ compatible. --- include/mysql/plugin.h | 3 ++- include/mysql/service_debug_sync.h | 4 ++++ 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/include/mysql/plugin.h b/include/mysql/plugin.h index d9aef6ac11c..87efbefde68 100644 --- a/include/mysql/plugin.h +++ b/include/mysql/plugin.h @@ -44,7 +44,8 @@ class THD; class Item; #define MYSQL_THD THD* #else -#define MYSQL_THD void* +struct THD; +typedef struct THD* MYSQL_THD; #endif typedef char my_bool; diff --git a/include/mysql/service_debug_sync.h b/include/mysql/service_debug_sync.h index 0bd49a13458..f7fdbf04832 100644 --- a/include/mysql/service_debug_sync.h +++ b/include/mysql/service_debug_sync.h @@ -351,7 +351,11 @@ extern void (*debug_sync_C_callback_ptr)(MYSQL_THD, const char *, size_t); #endif /* defined(ENABLED_DEBUG_SYNC) */ /* compatibility macro */ +#ifdef __cplusplus +#define DEBUG_SYNC_C(name) DEBUG_SYNC(nullptr, name) +#else #define DEBUG_SYNC_C(name) DEBUG_SYNC(NULL, name) +#endif #ifdef __cplusplus } From f862fe8b2bb359e0bbeb48d0d38047a95dc0e43c Mon Sep 17 00:00:00 2001 From: Yuchen Pei Date: Mon, 16 Dec 2024 10:26:21 +1100 Subject: [PATCH 008/118] MDEV-35641 bring call to use_all_columns() forward when reading from mysql.servers TABLE::use_all_columns turn on all bits of read_set, which is interpreted by innodb as a request to read all columns.

(so if the last SP execution ended with error resorces was not freeded on reinit before execution (cleanup() called before next execution) and destructor also was not called due to lack of delete call for the object) Result cleanup() renamed to reset_for_next_ps_execution() to better reflect function().

However, as not all nodes in Galera cluster are replica nodes, rows were not deleted from table. In this fix this is corrected so that mysql.gtid_slave_pos table is not replicated by Galera. Instead when Galera node receives GTID event and wsrep_gtid_mode=1, this event is stored to mysql.gtid_slave_pos table. Added test case galera_2primary_replica for 2 async primaries replicating to galera cluster. Added test case galera_circular_replication where async primary replicates to galera cluster and one of the galera cluster nodes is master to async replica. Modified test case galera_restart_replica to monitor gtid positions and rows in mysql.gtid_pos_table. --- .../galera_2nodes_as_replica_2primary.cnf | 70 ++++++ .../galera/r/galera_2primary_replica.result | 95 +++++++ .../r/galera_circular_replication.result | 138 +++++++++++ .../galera/r/galera_restart_replica.result | 191 ++++++++------ .../galera/t/galera_2primary_replica.cnf | 22 ++ .../galera/t/galera_2primary_replica.test | 170 +++++++++++++ .../galera/t/galera_circular_replication.cnf | 25 ++ .../galera/t/galera_circular_replication.test | 234 ++++++++++++++++++ .../galera/t/galera_restart_replica.test | 197 ++++++++++----- sql/rpl_gtid.cc | 50 +--- sql/wsrep_applier.cc | 5 + sql/wsrep_schema.cc | 80 +++++- sql/wsrep_schema.h | 14 +- 13 files changed, 1110 insertions(+), 181 deletions(-) create mode 100644 mysql-test/suite/galera/galera_2nodes_as_replica_2primary.cnf create mode 100644 mysql-test/suite/galera/r/galera_2primary_replica.result create mode 100644 mysql-test/suite/galera/r/galera_circular_replication.result create mode 100644 mysql-test/suite/galera/t/galera_2primary_replica.cnf create mode 100644 mysql-test/suite/galera/t/galera_2primary_replica.test create mode 100644 mysql-test/suite/galera/t/galera_circular_replication.cnf create mode 100644 mysql-test/suite/galera/t/galera_circular_replication.test diff --git a/mysql-test/suite/galera/galera_2nodes_as_replica_2primary.cnf b/mysql-test/suite/galera/galera_2nodes_as_replica_2primary.cnf new file mode 100644 index 00000000000..714caf6ee67 --- /dev/null +++ b/mysql-test/suite/galera/galera_2nodes_as_replica_2primary.cnf @@ -0,0 +1,70 @@ +# +# This .cnf file creates a setup with 2 standard MariaDB servers, followed by a 2-node Galera cluster +# + +# Use default setting for mysqld processes +!include include/default_mysqld.cnf + +[mysqld] +loose-innodb +log-bin=mysqld-bin +log-slave-updates +binlog-format=row +innodb-autoinc-lock-mode=2 +default-storage-engine=innodb +# enforce read-committed characteristics across the cluster +# wsrep-causal-reads=ON +wsrep-sync-wait=15 + +[mysqld.1] +wsrep-on=1 +server-id=1 +#galera_port=@OPT.port +#ist_port=@OPT.port +#sst_port=@OPT.port +wsrep_provider=@ENV.WSREP_PROVIDER +wsrep_cluster_address=gcomm:// +wsrep_provider_options='repl.causal_read_timeout=PT90S;base_port=@mysqld.1.#galera_port;evs.suspect_timeout=PT10S;evs.inactive_timeout=PT30S;evs.install_timeout=PT15S;gcache.size=10M' +wsrep_node_address='127.0.0.1:@mysqld.1.#galera_port' +wsrep_node_incoming_address=127.0.0.1:@mysqld.1.port +wsrep_sst_receive_address='127.0.0.1:@mysqld.1.#sst_port' + +[mysqld.2] +wsrep-on=1 +server-id=2 +#galera_port=@OPT.port +#ist_port=@OPT.port +#sst_port=@OPT.port +wsrep_provider=@ENV.WSREP_PROVIDER +wsrep_cluster_address='gcomm://127.0.0.1:@mysqld.1.#galera_port' +wsrep_provider_options='repl.causal_read_timeout=PT90S;base_port=@mysqld.2.#galera_port;evs.suspect_timeout=PT10S;evs.inactive_timeout=PT30S;evs.install_timeout=PT15S;gcache.size=10M' +wsrep_node_address='127.0.0.1:@mysqld.2.#galera_port' +wsrep_node_incoming_address=127.0.0.1:@mysqld.2.port +wsrep_sst_receive_address='127.0.0.1:@mysqld.2.#sst_port' + +[mysqld.3] +wsrep-on=OFF +server-id=3 +gtid_domain_id=3 + +[mysqld.4] +wsrep-on=OFF +server-id=4 +gtid_domain_id=4 + + +[sst] +sst-log-archive-dir=@ENV.MYSQLTEST_VARDIR/log + +[ENV] +NODE_MYPORT_1= @mysqld.1.port +NODE_MYSOCK_1= @mysqld.1.socket + +NODE_MYPORT_2= @mysqld.2.port +NODE_MYSOCK_2= @mysqld.2.socket + +NODE_MYPORT_3= @mysqld.3.port +NODE_MYSOCK_3= @mysqld.3.socket + +NODE_MYPORT_4= @mysqld.4.port +NODE_MYSOCK_4= @mysqld.4.socket diff --git a/mysql-test/suite/galera/r/galera_2primary_replica.result b/mysql-test/suite/galera/r/galera_2primary_replica.result new file mode 100644 index 00000000000..8bdbf5be962 --- /dev/null +++ b/mysql-test/suite/galera/r/galera_2primary_replica.result @@ -0,0 +1,95 @@ +connection node_2;

This results in inconsistencies between the master and slave when replicating transactions that target such tables (i.e. the primary server would correctly distribute archived rows amongst its partitions, whereas the replica would have all archived rows in a single partition). The function partition_info::vers_set_hist_part(THD*) is used to set the partition; however, its initial check for vers_require_hist_part(THD*) returns false, bypassing the rest of the function (which sets up the partition to use). This is because the actual check uses the LEX sql_command (via LEX::vers_history_generating()) to determine if the command is valid to generate history. Row injections donโ€™t have sql_commands though. This patch provides a fix which extends the check in vers_history_generating() to additionally allow row injections to be history generating (via the function LEX::is_stmt_row_injection()). Special thanks to Jan Lindstrom for his work in reproducing the bug, and providing an initial test case.

The FreeBSD inclusion of check_openssl_compatibility prevented any use of the crypto callbacks and as such the later differences where ignored. The later differences in coc_malloc didn't propegate to the other callback functions of CRYPTO_set_mem_functions where a reduced argument list also applied. Looking where[2] libressl added the functions it was of the same prototype 10 years ago so omitting any version check.

Make trx->wsrep flag initialize from THD object only once on InnoDB transaction start and don't change it throughout the transaction's lifetime. The flag is reset at commit time as before. Unconditionally set wsrep=OFF for THD objects that represent InnoDB background threads. Make Wsrep_schema::store_view() operate in its own transaction.

Cleanup: memdup_vcol() is static inline instead of macro + check OOM. --- mysql-test/suite/vcol/r/vcol_misc.result | 14 ++++++++++ mysql-test/suite/vcol/t/vcol_misc.test | 19 ++++++++++++++ sql/sql_insert.cc | 30 +++++++++++++++------ sql/table.cc | 33 ++++++++++++++---------- sql/table.h | 1 + 5 files changed, 75 insertions(+), 22 deletions(-) diff --git a/mysql-test/suite/vcol/r/vcol_misc.result b/mysql-test/suite/vcol/r/vcol_misc.result index 64c56e81815..2900cd4b4f4 100644 --- a/mysql-test/suite/vcol/r/vcol_misc.result +++ b/mysql-test/suite/vcol/r/vcol_misc.result @@ -577,3 +577,17 @@ drop table t; # # End of 10.4 tests # +# +# MDEV-26891 Segfault in Field::register_field_in_read_map upon INSERT DELAYED with virtual columns +# +CREATE TABLE t ( +id INT AUTO_INCREMENT, +a varchar(16) NOT NULL DEFAULT '', +b varchar(16) GENERATED ALWAYS AS (a) VIRTUAL, +KEY `col_year` (b(8),id) +) ENGINE=MyISAM; +INSERT DELAYED INTO t (a) VALUES ('foo'),('bar'); +DROP TABLE t; +# +# End of 10.5 tests +# diff --git a/mysql-test/suite/vcol/t/vcol_misc.test b/mysql-test/suite/vcol/t/vcol_misc.test index 83a06e83f6f..2709ff5b465 100644 --- a/mysql-test/suite/vcol/t/vcol_misc.test +++ b/mysql-test/suite/vcol/t/vcol_misc.test @@ -541,3 +541,22 @@ drop table t; --echo # --echo # End of 10.4 tests --echo # + +--echo # +--echo # MDEV-26891 Segfault in Field::register_field_in_read_map upon INSERT DELAYED with virtual columns +--echo # +CREATE TABLE t ( + id INT AUTO_INCREMENT, + a varchar(16) NOT NULL DEFAULT '', + b varchar(16) GENERATED ALWAYS AS (a) VIRTUAL, + KEY `col_year` (b(8),id) +) ENGINE=MyISAM; + +INSERT DELAYED INTO t (a) VALUES ('foo'),('bar'); + +# Cleanup +DROP TABLE t; + +--echo # +--echo # End of 10.5 tests +--echo # diff --git a/sql/sql_insert.cc b/sql/sql_insert.cc index 000695c5399..50a1a37e3ea 100644 --- a/sql/sql_insert.cc +++ b/sql/sql_insert.cc @@ -2674,12 +2674,21 @@ end_create: DBUG_RETURN(thd->is_error()); } -#define memdup_vcol(thd, vcol) \ - if (vcol) \ - { \ - (vcol)= (Virtual_column_info*)(thd)->memdup((vcol), sizeof(*(vcol))); \ - (vcol)->expr= NULL; \ +static inline +bool memdup_vcol(THD *thd, Virtual_column_info *&vcol) +{ + if (vcol) + { + vcol= (Virtual_column_info*)(thd->memdup(vcol, sizeof(*vcol))); + if (!vcol) + { + my_error(ER_OUT_OF_RESOURCES, MYF(0)); + return true; + } + vcol->expr= NULL; } + return false; +} /** As we can't let many client threads modify the same TABLE @@ -2820,9 +2829,12 @@ TABLE *Delayed_insert::get_local_table(THD* client_thd) (*field)->move_field_offset(adjust_ptrs); // Point at copy->record[0] (*field)->flags|= ((*org_field)->flags & LONG_UNIQUE_HASH_FIELD); (*field)->invisible= (*org_field)->invisible; - memdup_vcol(client_thd, (*field)->vcol_info); - memdup_vcol(client_thd, (*field)->default_value); - memdup_vcol(client_thd, (*field)->check_constraint); + if (memdup_vcol(client_thd, (*field)->vcol_info)) + goto error; + if (memdup_vcol(client_thd, (*field)->default_value)) + goto error; + if (memdup_vcol(client_thd, (*field)->check_constraint)) + goto error; if (*org_field == found_next_number_field) (*field)->table->found_next_number_field= *field; } @@ -2839,6 +2851,8 @@ TABLE *Delayed_insert::get_local_table(THD* client_thd) &error_reported, VCOL_INIT_DEPENDENCY_FAILURE_IS_WARNING))) goto error; + + copy->update_keypart_vcol_info(); } switch_defaults_to_nullable_trigger_fields(copy); diff --git a/sql/table.cc b/sql/table.cc index aaec593df76..11564e85af0 100644 --- a/sql/table.cc +++ b/sql/table.cc @@ -3952,6 +3952,24 @@ bool copy_keys_from_share(TABLE *outparam, MEM_ROOT *root) return 0; } +void TABLE::update_keypart_vcol_info() +{ + for (uint k= 0; k < s->keys; k++) + { + KEY &info_k= key_info[k]; + uint parts = (s->use_ext_keys ?

If optimization is not possible it goes normal branch for UPDATE to history and repeats the cycle of INSERT. The failure was in normal branch when we tried UPDATE to history but such history already exists from previous cycles. There is no such failures in optimized branch because vers_insert_history_row() already ignores duplicates. The fix ignores duplicate errors for UPDATE to history and does DELETE instead. --- mysql-test/suite/versioning/r/replace.result | 16 +++++++++++++++ mysql-test/suite/versioning/t/replace.test | 15 ++++++++++++++ sql/sql_insert.cc | 21 ++++++++++++++++++-- 3 files changed, 50 insertions(+), 2 deletions(-) diff --git a/mysql-test/suite/versioning/r/replace.result b/mysql-test/suite/versioning/r/replace.result index 8ac4047c5ff..c64f42ee7cf 100644 --- a/mysql-test/suite/versioning/r/replace.result +++ b/mysql-test/suite/versioning/r/replace.result @@ -27,7 +27,9 @@ id x current 1 2 0 1 3 1 drop table t; +# # MDEV-15645 Assertion `table->insert_values' failed in write_record upon REPLACE into a view with underlying versioned table +# create or replace table t1 (a int, b int, primary key (a), unique(b)) with system versioning; insert into t1 values (1,1); create or replace table t2 (c int); @@ -48,7 +50,9 @@ INSERT INTO t1 () VALUES (),(),(),(),(),(); UPDATE IGNORE t1 SET f = 1; REPLACE t1 SELECT * FROM t1; DROP TABLE t1; +# # MDEV-22540 ER_DUP_ENTRY upon REPLACE or Assertion failed +# set timestamp=1589245268.41934; create table t1 (a int primary key) with system versioning; insert into t1 values (1),(2); @@ -72,3 +76,15 @@ Warnings: Warning 1062 Duplicate entry '1' for key 'a' load data infile '15330.data' replace into table t1 (a,b,c); drop table t1; +# +# MDEV-35343 unexpected replace behaviour when long unique index on system versioned table +# +create table t1 (data char(10)); +insert into t1 values ('o'); +alter ignore table t1 add unique index (data); +alter ignore table t1 add unique index (data); +Warnings: +Note 1831 Duplicate index `data_2`.

It cannot use ha_delete_row() handler (H2) as it is different search mode: inited == INDEX for H1, inited == RND for H2. So, read handler H1 uses index while write handler H2 uses random access. For going next record in H1 there is info->last_pos optimization for stepping index via tree_search_next(). This optimization can work with deleted rows only if delete is conducted in the same handler, there is: 67 int hp_rb_delete_key(HP_INFO *info, register HP_KEYDEF *keyinfo, 68 const uchar *record, uchar *recpos, int flag) 69 { ... 74 if (flag) 75 info->last_pos= NULL; /* For heap_rnext/heap_rprev */ But this cannot work for different handler. So, last_pos in H1 after delete in H2 contains stale info->parents array and last_pos points into that parents. In the specific test case last_pos' parent is already freed node and tree_search_next() steps into it. The fix invalidates local savings of info->parents and info->last_pos based on key_version. Record deletion increments share->key_version in H2, so in H1 we know the tree might be changed. Another good measure would be to use H1 for delete. But this is bigger refactoring than just bug fixing. --- mysql-test/suite/heap/heap.result | 7 +++++++ mysql-test/suite/heap/heap.test | 9 +++++++++ storage/heap/hp_rnext.c | 4 +++- storage/heap/hp_rprev.c | 3 ++- 4 files changed, 21 insertions(+), 2 deletions(-) diff --git a/mysql-test/suite/heap/heap.result b/mysql-test/suite/heap/heap.result index 67641d51b02..11c50d97475 100644 --- a/mysql-test/suite/heap/heap.result +++ b/mysql-test/suite/heap/heap.result @@ -877,3 +877,10 @@ DELETE FROM t1 WHERE ts = 1 AND color = 'GREEN';

Fixed this by switching my_malloc_size_cb_func() to use space on the stack instead. --- mysql-test/main/errors.result | 13 +++++++++++++ mysql-test/main/errors.test | 20 ++++++++++++++++++++ sql/mysqld.cc | 18 +++++------------- 3 files changed, 38 insertions(+), 13 deletions(-) diff --git a/mysql-test/main/errors.result b/mysql-test/main/errors.result index baa2e0ad3c0..5b469b640f8 100644 --- a/mysql-test/main/errors.result +++ b/mysql-test/main/errors.result @@ -231,3 +231,16 @@ Error 1327 Undeclared variable: foo Error 1305 PROCEDURE P1 does not exist drop procedure P1; # End of 10.4 tests +# +# MDEV-35828: Assertion fails in alloc_root() when memory causes it to call itself +# +CREATE TEMPORARY TABLE t1 (a INT,b INT); +INSERT INTO t1 VALUES (1,1),(2,2); +SET +@tmp=@@max_session_mem_used, +max_session_mem_used=8192; +SELECT * FROM (t1 AS t2 LEFT JOIN t1 AS t3 USING (a)),t1; +ERROR HY000: The MariaDB server is running with the --max-session-mem-used=8192 option so it cannot execute this statement +DROP TABLE t1; +SET max_session_mem_used=@tmp; +# End of 10.6 tests diff --git a/mysql-test/main/errors.test b/mysql-test/main/errors.test index cc5cad2a68e..87d6d2fdec9 100644 --- a/mysql-test/main/errors.test +++ b/mysql-test/main/errors.test @@ -284,3 +284,23 @@ show warnings; drop procedure P1; -- echo # End of 10.4 tests + + +--echo # +--echo # MDEV-35828: Assertion fails in alloc_root() when memory causes it to call itself +--echo # +CREATE TEMPORARY TABLE t1 (a INT,b INT); +INSERT INTO t1 VALUES (1,1),(2,2); + +SET + @tmp=@@max_session_mem_used, + max_session_mem_used=8192; + +--error ER_OPTION_PREVENTS_STATEMENT +SELECT * FROM (t1 AS t2 LEFT JOIN t1 AS t3 USING (a)),t1; + +DROP TABLE t1; +SET max_session_mem_used=@tmp; + + +--echo # End of 10.6 tests diff --git a/sql/mysqld.cc b/sql/mysqld.cc index c798956910f..d6dd8a566af 100644 --- a/sql/mysqld.cc +++ b/sql/mysqld.cc @@ -3513,22 +3513,14 @@ static void my_malloc_size_cb_func(long long size, my_bool is_thread_specific) LOCK_thd_kill here (the limit will be enforced on the next allocation). */ if (!mysql_mutex_trylock(&thd->LOCK_thd_kill)) { - char buf[50], *buf2; + char buf[50], buf2[256]; thd->set_killed_no_mutex(KILL_QUERY); my_snprintf(buf, sizeof(buf), "--max-session-mem-used=%llu", thd->variables.max_mem_used); - if ((buf2= (char*) thd->alloc(256))) - { - my_snprintf(buf2, 256, - ER_THD(thd, ER_OPTION_PREVENTS_STATEMENT), buf); - thd->set_killed_no_mutex(KILL_QUERY, - ER_OPTION_PREVENTS_STATEMENT, buf2); - } - else - { - thd->set_killed_no_mutex(KILL_QUERY, ER_OPTION_PREVENTS_STATEMENT, - "--max-session-mem-used"); - } + my_snprintf(buf2, 256, + ER_THD(thd, ER_OPTION_PREVENTS_STATEMENT), buf); + thd->set_killed_no_mutex(KILL_QUERY, + ER_OPTION_PREVENTS_STATEMENT, buf2); mysql_mutex_unlock(&thd->LOCK_thd_kill); } } From b82abc71639661c642b9d753393be0f85e09c101 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marko=20M=C3=A4kel=C3=A4?= Date: Wed, 15 Jan 2025 16:55:01 +0200 Subject: [PATCH 035/118] MDEV-35701 trx_t::autoinc_locks causes unnecessary dynamic memory allocation trx_t::autoinc_locks: Use small_vector in order to avoid any dynamic memory allocation in the most common case (a statement is holding AUTO_INCREMENT locks on at most 4 tables or partitions). lock_cancel_waiting_and_release(): Instead of removing elements from the middle, simply assign nullptr, like lock_table_remove_autoinc_lock().

The first byte of the key is by default 0, and in rare circumstances it is changed to a different value: when semi_table_lock is set to 1; and when using casual read. When this happens, often a new connection is created with the new key. Neither case is useful: the description of semi_table_lock has nothing to do with creation of new connections and the parameter itself was deprecated for 10.7+ (MDEV-28829) and marked for deletion (MDEV-28830); while new threads created by non-zero spider_casual_read causes only threads to be idle, thus not achieving any gain, see MDEV-26151, and the param has also been deprecated in 11.5+ (MDEV-31789). The relevant code adds unnecessary complexity to the spider code. This change does not reduce parallelism, because already when bgs mode is on a background thread is created per partition, and there is no evidence spider creates multiple threads for one partition. If the needs of such cases arise it will be a separate issue. --- storage/spider/ha_spider.cc | 3 --- storage/spider/spd_conn.cc | 5 ----- storage/spider/spd_table.cc | 19 ------------------- storage/spider/spd_trx.cc | 22 +--------------------- 4 files changed, 1 insertion(+), 48 deletions(-) diff --git a/storage/spider/ha_spider.cc b/storage/spider/ha_spider.cc index 54a2fd110f3..0089b1fa0f6 100644 --- a/storage/spider/ha_spider.cc +++ b/storage/spider/ha_spider.cc @@ -1006,9 +1006,6 @@ int ha_spider::reset() THD *thd = ha_thd();

There are two branches in spider_check_trx_and_get_conn, often called at the beginning of a spider DML, depending on whether an update of various spider fields is needed. If it is determined to be needed, the updating may NULL the connections associated with the spider handler, which subsequently causes a call to spider_get_conn() which updates conn->queued_connect_share with the SPIDER_SHARE associated with the spider handler. We make it so that conn->queued_connect_share is updated regardless of the branch it enters, so that it will not be a stale and potentially already freed one. --- .../spider/bugfix/r/mdev_34849.result | 24 +++++++++ .../spider/bugfix/t/mdev_34849.test | 52 +++++++++++++++++++ storage/spider/spd_trx.cc | 2 + 3 files changed, 78 insertions(+) create mode 100644 storage/spider/mysql-test/spider/bugfix/r/mdev_34849.result create mode 100644 storage/spider/mysql-test/spider/bugfix/t/mdev_34849.test diff --git a/storage/spider/mysql-test/spider/bugfix/r/mdev_34849.result b/storage/spider/mysql-test/spider/bugfix/r/mdev_34849.result new file mode 100644 index 00000000000..9433dd7f679 --- /dev/null +++ b/storage/spider/mysql-test/spider/bugfix/r/mdev_34849.result @@ -0,0 +1,24 @@ +# +# MDEV-34849 SIGSEGV in server_mysql_real_connect, spider_db_connect, __strcmp_evex and __strnlen_evex, ASAN heap-use-after-free in spider_db_connect on INSERT +# +INSTALL SONAME 'ha_spider'; +CREATE TABLE t1 (c INT) ENGINE=Spider; +CREATE TABLE t2 (c INT) ENGINE=Spider; +SELECT * FROM t2; +ERROR HY000: Unable to connect to foreign data source: localhost +set @old_table_open_cache=@@global.table_open_cache; +SET GLOBAL table_open_cache=0; +Warnings: +Warning 1292 Truncated incorrect table_open_cache value: '0' +set autocommit=0; +/* 1 */ INSERT INTO t1 VALUES (0); +ERROR HY000: Unable to connect to foreign data source: localhost +/* 2 */ INSERT INTO t2 VALUES (0); +ERROR HY000: Unable to connect to foreign data source: localhost +set global spider_connect_error_interval=0; +/* 3 */ INSERT INTO t1 VALUES (0); +ERROR HY000: Unable to connect to foreign data source: localhost +drop table t1, t2; +set global table_open_cache=@old_table_open_cache; +Warnings: +Warning 1620 Plugin is busy and will be uninstalled on shutdown diff --git a/storage/spider/mysql-test/spider/bugfix/t/mdev_34849.test b/storage/spider/mysql-test/spider/bugfix/t/mdev_34849.test new file mode 100644 index 00000000000..4890abf4c7d --- /dev/null +++ b/storage/spider/mysql-test/spider/bugfix/t/mdev_34849.test @@ -0,0 +1,52 @@ +--echo # +--echo # MDEV-34849 SIGSEGV in server_mysql_real_connect, spider_db_connect, __strcmp_evex and __strnlen_evex, ASAN heap-use-after-free in spider_db_connect on INSERT +--echo # + +INSTALL SONAME 'ha_spider'; + +CREATE TABLE t1 (c INT) ENGINE=Spider; +CREATE TABLE t2 (c INT) ENGINE=Spider; + +# So that t2 is inserted into spider_init_error_tables and in INSERT +# INTO t2 we go into failure mode in spider_get_share() +--error 1429 +SELECT * FROM t2; + +# Resets the table cache so that the next two queries will call +# ha_spider::open() on t1 and t2 respectively +set @old_table_open_cache=@@global.table_open_cache; +SET GLOBAL table_open_cache=0; + +# This causes trx_ha->wait_for_reusing to remain false during the +# (non-)rollback at the end of the first INSERT INTO t1 statement, so +# that the second INSERT INTO t1 enters the branch in +# spider_check_trx_and_get_conn() that does not update spider fields +# including NULLing its associated connections. +set autocommit=0; + +# Misses the table cache when opening the table.

The bug led mostly to wrong results for such queries. A subquery is called degenerated if it is of the form (SELECT ...). For degenerated subqueries of the form (SELECT ) the transformation (SELECT ) => usually is applied. However if contains set functions or window functions such rewriting is not valid for an obvious reason. The code before this patch erroneously applied the transformation when contained window functions and did not contain set functions.

When reading the active relay log, this flag is also being used by the IO thread, and setting it can randomly cause the IO thread to wrongly detect IO error on writing and permanently disable the relay log. This was seen sporadically in test case rpl.rpl_from_mysql80. The read error set by the SQL thread in the IO_CACHE would be interpreted as a write error by the IO thread, which would cause it to throw a fatal error and close the relay log. And this would later cause CHANGE MASTER to try to purge a closed relay log, resulting in nullptr crash. SQL thread is not able to parse an event read from the relay log. This can happen like here when replicating unknown events from a MySQL master, potentially also for other reasons. Also fix a mistake in my_b_flush_io_cache() introduced back in 2001 (fa09f2cd7e7) where my_b_flush_io_cache() could wrongly return an error set in IO_CACHE::error, even if the flush operation itself succeeded. Also fix another sporadic failure in rpl.rpl_from_mysql80 where the outout of MASTER_POS_WAIT() depended on timing of SQL and IO thread.

Server crash taken place by the reason of dereferencing null pointer in condition of DBUG_ASSERT inside the method Field_iterator_natural_join::next() There the data member cur_column_ref->table_field->field has the nullptr value that was reset at the end of first execution of a stored routine when the standalone procedure cleanup_items() called by the method sp_head::execute. Later this data member is not re-initialized and never referenced in any place except the DBUG_ASSERT on second and later invocations of the stored routine. To fix the issue, the assert's condition should be augmented by a condition '|| !cur_column_ref->table_field' before dereferencing cur_column_ref->table_field. Such extra checking is aligned with conditions used by DBUG_ASSERT macros used by implementation of the class Field_iterator_table_ref that aggregated the class Field_iterator_natural_join. --- mysql-test/main/sp-bugs.result | 27 +++++++++++++++++++++++++++ mysql-test/main/sp-bugs.test | 31 +++++++++++++++++++++++++++++++ sql/table.cc | 1 + 3 files changed, 59 insertions(+) diff --git a/mysql-test/main/sp-bugs.result b/mysql-test/main/sp-bugs.result index a166a5a0a9a..bd5883f0a04 100644 --- a/mysql-test/main/sp-bugs.result +++ b/mysql-test/main/sp-bugs.result @@ -363,3 +363,30 @@ ERROR HY000: Unknown thread id: 0 # # End of 10.4 tests # +# +# MDEV-24935: Server crashes in Field_iterator_natural_join::next or Field_iterator_table_ref::set_field_iterator upon 2nd execution of SP +# +CREATE TABLE t1 (a INT); +CREATE TABLE t2 (b INT, c INT); +CREATE TABLE t3 (d INT); +CREATE PROCEDURE sp() SELECT * FROM t1 JOIN t2 JOIN t3 USING (x); +CALL sp; +ERROR 42S22: Unknown column 'x' in 'from clause' +CALL sp; +ERROR 42S22: Unknown column 'x' in 'from clause' +# Clean up +DROP PROCEDURE sp; +DROP TABLE t1, t2, t3; +CREATE TABLE t1 (c1 INT,c2 INT); +CREATE TABLE t2 (c INT,c2 INT); +CREATE PROCEDURE p2 (OUT i INT,OUT o INT) READS SQL DATA DELETE a2,a3 FROM t1 AS a1 JOIN t2 AS a2 NATURAL JOIN t2 AS a3; +CALL p2 (@c,@a); +ERROR 23000: Column 'c2' in from clause is ambiguous +CALL p2 (@a,@c); +ERROR 23000: Column 'c2' in from clause is ambiguous +# Clean up +DROP PROCEDURE p2; +DROP TABLE t1, t2; +# +# End of 10.5 tests +# diff --git a/mysql-test/main/sp-bugs.test b/mysql-test/main/sp-bugs.test index 18fe14dc8bc..f44216fbf46 100644 --- a/mysql-test/main/sp-bugs.test +++ b/mysql-test/main/sp-bugs.test @@ -386,3 +386,34 @@ KILL (('x' IN ( SELECT 1)) MOD 44); --echo # --echo # End of 10.4 tests --echo # + +--echo # +--echo # MDEV-24935: Server crashes in Field_iterator_natural_join::next or Field_iterator_table_ref::set_field_iterator upon 2nd execution of SP +--echo # +CREATE TABLE t1 (a INT); +CREATE TABLE t2 (b INT, c INT); +CREATE TABLE t3 (d INT); +CREATE PROCEDURE sp() SELECT * FROM t1 JOIN t2 JOIN t3 USING (x); +--error ER_BAD_FIELD_ERROR +CALL sp; +--error ER_BAD_FIELD_ERROR +CALL sp; +--echo # Clean up +DROP PROCEDURE sp; +DROP TABLE t1, t2, t3; + +CREATE TABLE t1 (c1 INT,c2 INT); +CREATE TABLE t2 (c INT,c2 INT); +CREATE PROCEDURE p2 (OUT i INT,OUT o INT) READS SQL DATA DELETE a2,a3 FROM t1 AS a1 JOIN t2 AS a2 NATURAL JOIN t2 AS a3; + +--error ER_NON_UNIQ_ERROR +CALL p2 (@c,@a); +--error ER_NON_UNIQ_ERROR +CALL p2 (@a,@c); +--echo # Clean up +DROP PROCEDURE p2; +DROP TABLE t1, t2; + +--echo # +--echo # End of 10.5 tests +--echo # diff --git a/sql/table.cc b/sql/table.cc index 0aad7ae24e1..978dbee254e 100644 --- a/sql/table.cc +++ b/sql/table.cc @@ -6948,6 +6948,7 @@ void Field_iterator_natural_join::next() { cur_column_ref= column_ref_it++; DBUG_ASSERT(!cur_column_ref || ! cur_column_ref->table_field || + !cur_column_ref->table_field->field || cur_column_ref->table_ref->table == cur_column_ref->table_field->field->table); } From 40a23e08e605ea8a15555d204e8feaee297bd988 Mon Sep 17 00:00:00 2001 From: Vladislav Vaintroub Date: Fri, 24 Jan 2025 12:07:42 +0100 Subject: [PATCH 072/118] WolfSSL - make it compilable also with older versions of Windows SDK. followup 136e866119779668736a4d52ae3301e1f6e3eff2 Remove HAVE_CONFIG_H from wolfssl compilation.

DROP TABLE takes MDL locks on both child and its parent table, however it only it did not add certification keys for the parent table. This patch adds the following: * Append certification keys corresponding to all parent tables before DROP TABLE replication. * Fix wsrep_append_fk_parent_table() so that it works when it is given a table list containing temporary tables. * Make sure function wsrep_append_fk_parent_table() is only called for local transaction. That was not the case for ALTER TABLE. * Add a test case that verifies that UPDATE parent depends on preceeding DROP TABLE child. * Adapt galera_ddl_fk_conflict test to work with DROP TABLE as well.

Reason was that some client threads has stmt_da in state DA_EOF, and this state was earlier used to detect if client connection was issuing SHUTDOWN command. To fix this, the connection executing SHUTDOWN is now detected by looking at the actual command being executed: thd->get_command() == COM_SHUTDOWN During replication shutdown, all other connections but the SHUTDOWN executor, are terminated. This commit has new mtr test galera.galera_threadpool, which opens a number of threadpool client connections, and then restarts the node to verify that connections in threadpool are terminated during shutdown.

Test rpl.rpl_parallel_gco_wait_kill has a race condition where it identifies that SQL using its state as "Slave has read all relay log", and immediately tries to save the thread id of the SQL thread by querying for threads with that same state. However, the state of the SQL thread may change in-between this time, leading to the query that saves the SQL thread finding no thread id that matches that state. Commit 3ee6f69d49a58422f994f51a0bd7a0cb1242a3dd aimed to fix this in 10.11+ by simplifying the query string to "%relay log%"; however, it could still fail (though less often). This commit instead changes the query to find the SQL thread from using some state, to using the command "Slave_SQL", which will not change --- mysql-test/suite/rpl/t/rpl_parallel_gco_wait_kill.test | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mysql-test/suite/rpl/t/rpl_parallel_gco_wait_kill.test b/mysql-test/suite/rpl/t/rpl_parallel_gco_wait_kill.test index d918b2ea692..f4d9777f75e 100644 --- a/mysql-test/suite/rpl/t/rpl_parallel_gco_wait_kill.test +++ b/mysql-test/suite/rpl/t/rpl_parallel_gco_wait_kill.test @@ -297,7 +297,7 @@ SET GLOBAL slave_parallel_threads=10; # Find the thread id of the driver SQL thread that we want to kill. --let $wait_condition= SELECT COUNT(*) = 1 FROM INFORMATION_SCHEMA.PROCESSLIST WHERE STATE LIKE '%Slave has read all relay log%' --source include/wait_condition.inc ---let $thd_id= `SELECT ID FROM INFORMATION_SCHEMA.PROCESSLIST WHERE STATE LIKE '%Slave has read all relay log%'` +--let $thd_id= `SELECT ID FROM INFORMATION_SCHEMA.PROCESSLIST WHERE COMMAND LIKE 'Slave_SQL'` SET @old_max_queued= @@GLOBAL.slave_parallel_max_queued; SET GLOBAL slave_parallel_max_queued=9000; From e33064e0fcf991ec2d0535396a6061dad90c2a3e Mon Sep 17 00:00:00 2001 From: Nikita Malyavin Date: Thu, 16 Jan 2025 01:44:06 +0100 Subject: [PATCH 080/118] MDEV-27769 Assertion failed in Field::ptr_in_record upon UPDATE in ORACLE mode table->move_fields has some limitations: 1.

This could lead to a slow execution of the procedure. Also in some cases the bug prevented building conditions that could be pushed from the HAVING condition into the WHERE condition of a query if the conditions to be built used local variables of a stored procedure. To failure to build such pushable conditions was due to lack of a proper implementation of the virtual method to copy items for the objects of the class Item_splocal. Approved by Igor Babaev who had to change the original fix that just added the regular copying of the nodes of the Item_splocal class to take into account the wrappers do_get_copy() and do_build_clone() introduced after the fix had been prepared. He also changed the test case to demonstrate that the fix was really needed for pushdown from HAVING into WHERE. --- mysql-test/main/sp.result | 176 ++++++++++++++++++++++++++++++++++++++ mysql-test/main/sp.test | 88 +++++++++++++++++++ sql/item.h | 5 +- 3 files changed, 267 insertions(+), 2 deletions(-) diff --git a/mysql-test/main/sp.result b/mysql-test/main/sp.result index 1b3405e47b1..204af23f09f 100644 --- a/mysql-test/main/sp.result +++ b/mysql-test/main/sp.result @@ -8974,3 +8974,179 @@ DROP PROCEDURE p1;

Let us relax those assertions for Galera transactions, to allow an implicit commit after an internally executed XA PREPARE.
