Re: [Maria-developers] [Commits] 70b0c838fad: MDEV-21922: Allow packing addon fields even if they don't honour max_length_for_sort_data
by Sergey Petrunia 13 Mar '20

Hi Varun, * The patch needs a testcase * Please check the comment at https://jira.mariadb.org/browse/MDEV-21922 , and add a comment in filesort_use_addons() about the use of upper bound for computations. * Ok to push after the above is addressed.

Hi, Nikita!

Fix: === "mysql_upgrade" test should check for the presence of data in "mysql.slave_master_info" and "mysql.slave_relay_log_info" tables. When tables have some data the upgrade script should report a warning which hints users that the data in repository tables will be ignored. --- client/mysql_upgrade.c | 61 +++++++++- .../main/rpl_mysql_upgrade_slave_repo_check.result | 33 ++++++ .../main/rpl_mysql_upgrade_slave_repo_check.test | 127 +++++++++++++++++++++ 3 files changed, 220 insertions(+), 1 deletion(-) diff --git a/client/mysql_upgrade.c b/client/mysql_upgrade.c index 4e17089593f..bea82c2a112 100644 --- a/client/mysql_upgrade.c +++ b/client/mysql_upgrade.c @@ -1014,6 +1014,64 @@ static int install_used_engines(void) return 0;

[Maria-developers] Please review MDEV-17832 Protocol: extensions for Pluggable types and JSON, GEOMETRY
by Alexander Barkov 06 Mar '20

06 Mar '20

Hi, Sergei, Georg, Please review a fixed version of the patch for MDEV-17832. There are two files attached: - mdev-17821.v18.diff (server changes) - mdev-17821-cli.v06.diff (libmariadb changes) Comparing to the previous version, this version: 1. Adds a new structure MA_FIELD_EXTENSION 2. Moves extended data type information from MYSQL_FIELD to MYSQL_FIELD::extension in the client-server implementation. Note, in case of embedded server, the extended metadata is stored directly to MYSQL_FIELD. 3. Adds a new API function mariadb_field_metadata_attr(), to extract metadata from MYSQL_FIELD. 4. Changes the way how the metadata is packed on the wire from "easily human readable" to "easily parse-able", which: - makes the things faster - allows to transfer arbitrary binary data in the future, if needed. Every metadata chunk is now encoded as: a. chunk type (1 byte) b. chunk data length (1 byte) c. chunk data (according to #b) For now, two chunk types are implemented: - data type name (used for GEOMETRY sub-types, and for INET6) - format name (for JSON) Thanks!

[Maria-developers] Fwd: [andrei.elkin@mariadb.com] 30a3ee1b8ce: MDEV-21469: Implement crash-safe logging of the user XA
by andrei.elkin＠pp.inet.fi 04 Mar '20

04 Mar '20

Kristian, Fyi, here is the XA replication event recovery part. It's largely coded by Sujatha Sivakumar. The latest patch resides in bb-10.5-MDEV_21469. Cheers, Andrei revision-id: 30a3ee1b8ce98ea33dfc0595207bf467cdb91def (mariadb-10.5.0-285-g30a3ee1b8ce) parent(s): 77f4a1938f2a069174e07b3453fa0f99ba171a2e author: Sujatha committer: Andrei Elkin timestamp: 2020-03-04 14:45:01 +0200 message: MDEV-21469: Implement crash-safe logging of the user XA Description: Make XA PREPARE, XA COMMIT and XA ROLLBACK statements crash-safe. Implementation: In order to ensure consistent replication XA statements like XA PREPARE, XA COMMIT and XA ROLLBACK are firstly written into the binary log and then to storage engine. In a case server crashes after writing to binary log but not in storage engine it will lead to inconsistent state. In order to make both binary log and engine to be consistent crash recovery needs to be initiated. During crash recovery binary log needs to be parsed to identify the transactions which are present only in binary log and not present in engine. These transaction are resubmitted to engine to make it consistent along with binary log. --- .../r/binlog_xa_multi_binlog_crash_recovery.result | 40 +++ .../t/binlog_xa_multi_binlog_crash_recovery.test | 85 +++++ .../suite/rpl/r/rpl_xa_commit_crash_safe.result | 50 +++ .../suite/rpl/r/rpl_xa_event_apply_failure.result | 60 ++++ .../rpl/r/rpl_xa_prepare_commit_prepare.result | 48 +++ .../suite/rpl/r/rpl_xa_prepare_crash_safe.result | 62 ++++ .../rpl/r/rpl_xa_rollback_commit_crash_safe.result | 47 +++ .../suite/rpl/t/rpl_xa_commit_crash_safe.test | 98 ++++++ .../suite/rpl/t/rpl_xa_event_apply_failure.test | 119 +++++++ .../suite/rpl/t/rpl_xa_prepare_commit_prepare.test | 95 ++++++ .../suite/rpl/t/rpl_xa_prepare_crash_safe.test | 117 +++++++ .../rpl/t/rpl_xa_rollback_commit_crash_safe.test | 97 ++++++ sql/handler.cc | 29 +- sql/handler.h | 12 +- sql/log.cc | 379 +++++++++++++++++++-- sql/log.h | 8 +- sql/log_event.cc | 18 +- sql/log_event.h | 15 +- sql/mysqld.cc | 4 +- sql/xa.cc | 4 + 20 files changed, 1353 insertions(+), 34 deletions(-) diff --git a/mysql-test/suite/binlog/r/binlog_xa_multi_binlog_crash_recovery.result b/mysql-test/suite/binlog/r/binlog_xa_multi_binlog_crash_recovery.result new file mode 100644 index 00000000000..a09472aa94c --- /dev/null +++ b/mysql-test/suite/binlog/r/binlog_xa_multi_binlog_crash_recovery.result @@ -0,0 +1,40 @@ +RESET MASTER; +CREATE TABLE t1 (a INT PRIMARY KEY, b MEDIUMTEXT) ENGINE=Innodb; +CALL mtr.add_suppression("Found 1 prepared XA transactions"); +connect con1,localhost,root,,; +SET DEBUG_SYNC= "simulate_hang_after_binlog_prepare SIGNAL con1_ready WAIT_FOR con1_go"; +SET GLOBAL DEBUG_DBUG="d,simulate_crash_after_binlog_prepare"; +XA START 'xa1'; +INSERT INTO t1 SET a=1; +XA END 'xa1'; +XA PREPARE 'xa1';; +connection default; +SET DEBUG_SYNC= "now WAIT_FOR con1_ready"; +FLUSH LOGS; +FLUSH LOGS; +FLUSH LOGS; +show binary logs; +Log_name File_size +master-bin.000001 # +master-bin.000002 # +master-bin.000003 # +master-bin.000004 # +include/show_binlog_events.inc +Log_name Pos Event_type Server_id End_log_pos Info +master-bin.000004 # Format_desc # # SERVER_VERSION, BINLOG_VERSION +master-bin.000004 # Gtid_list # # [#-#-#] +master-bin.000004 # Binlog_checkpoint # # master-bin.000001 +SET DEBUG_SYNC= "now SIGNAL con1_go"; +connection con1; +ERROR HY000: Lost connection to MySQL server during query +connection default; +XA RECOVER; +formatID gtrid_length bqual_length data +1 3 0 xa1 +XA COMMIT 'xa1'; +SELECT * FROM t1; +a b +1 NULL +connection default; +DROP TABLE t1; +SET debug_sync = 'reset'; diff --git a/mysql-test/suite/binlog/t/binlog_xa_multi_binlog_crash_recovery.test b/mysql-test/suite/binlog/t/binlog_xa_multi_binlog_crash_recovery.test new file mode 100644 index 00000000000..aa8d3d04fc7 --- /dev/null +++ b/mysql-test/suite/binlog/t/binlog_xa_multi_binlog_crash_recovery.test @@ -0,0 +1,85 @@ +# ==== Purpose ==== +# +# Test verifies that XA crash recovery works fine across multiple binary logs. +# +# ==== Implementation ==== +# +# Steps: +# 0 - Generate an explicit XA transaction.

[Maria-developers] [andrei.elkin@mariadb.com] 25fe744e5c3: MDEV-742 XA PREPAREd transaction survive disconnect/server restart

Howdy, Kristian. I am forwarding for your attention a patch that HEADs bb-10.5-mdev_742 branch. While it's of some size maybe you'll find some time to review changes/extension esp done to the pararellel slave. Looking forward to hear from you! Thanks. Andrei revision-id: 25fe744e5c3d2e8f7d3db7eed37d8e412837457b (mariadb-10.5.0-283-g25fe744e5c3) parent(s): 36cebe53a3645bf1e665ffdf5b552cabcc1e8e56 author: Andrei Elkin committer: Andrei Elkin timestamp: 2020-03-04 15:48:43 +0200 message: MDEV-742 XA PREPAREd transaction survive disconnect/server restart Lifted long standing limitation to the XA of rolling it back at the transaction's connection close even if the XA is prepared. Prepared XA-transaction is made to sustain connection close or server restart. The patch consists of - binary logging extension to write prepared XA part of transaction signified with its XID in a new XA_prepare_log_event. The concusion part - with Commit or Rollback decision - is logged separately as Query_log_event. That is in the binlog the XA consists of two separate group of events. That makes the whole XA possibly interweaving in binlog with other XA:s or regular transaction but with no harm to replication and data consistency. Gtid_log_event receives two more flags to identify which of the two XA phases of the transaction it represents. With either flag set also XID info is added to the event. - engines are made aware of the server policy to keep up user prepared XA:s so they (Innodb, rocksdb) don't roll them back anymore at their disconnect methods. - slave applier is refined to cope with two phase logged XA:s including parallel modes of execution. This patch does not address crash-safe logging of the new events which is being addressed by MDEV-21469, its commit is to be published shortly. There's a list of fixes to 10.5 that were required by this MDEV, incl MDEV-21856: XID::formatID is constrained to 4 bytes by requirements of cross-platform replication and Innodb legacy.
