      MDEV-28005 Deprecate Spider plugin variables regarding UDFs · f78fdf08
      Nayuta Yanagisawa authored
      Configuring UDFs via plugin variables looks not a good idea.
      The more variables Spider has, the more complex it becomes.
      Further, I expect that only a few users use Spider UDFs.
      
      Deprecate the following plugin variables regarding Spider UDFs:
      
      * spider_udf_ds_bulk_insert_rows
      * spider_udf_ds_table_loop_mode
      * spider_udf_ds_use_real_table
      * spider_udf_ct_bulk_insert_interval
      * spider_udf_ct_bulk_insert_rows
      
      spider_udf_table_lock_mutex_count and spider_udf_table_mon_mutex_count
      are also for tweaking UDFs but they are already read-only. So,
      there is no need to deprecate them.

      MDEV-27931: buf_page_is_corrupted() wrongly claims corruption · 303448bc
      Marko Mäkelä authored
      In commit 437da7bc (MDEV-19534),
      the default value of the global variable srv_checksum_algorithm
      in innochecksum was changed from SRV_CHECKSUM_ALGORITHM_INNODB
      to implied 0 (innodb_checksum_algorithm=crc32). As a result,
      the function buf_page_is_corrupted() would by default invoke
      buf_calc_page_crc32() in innochecksum, and crc32_inited would hold.
      
      This would cause "innochecksum" to fail on a particular page.
      
      The actual problem is older, introduced in 2011 in
      mysql/mysql-server@17e497bdb793bc6b8360aa1c626dcd8bb5cfad1b
      (MySQL 5.6.3). It should affect the validation of pages of old
      data files that were written with innodb_checksum_algorithm=innodb.
      When using innodb_checksum_algorithm=crc32 (the default setting
      since MariaDB Server 10.2), some valid pages would be rejected
      only because exactly one of the two checksum fields accidentally
      matches the innodb_checksum_algorithm=crc32 value.
      
      buf_page_is_corrupted(): Simplify the logic of non-strict
      checksum validation, by always invoking buf_calc_page_crc32().
      Remove a bogus condition that if only one of the checksum fields
      contains the value returned by buf_calc_page_crc32(), the page
      is corrupted.

      MDEV-28181 The innochecksum -w option was inadvertently removed · b2fa874e
      Marko Mäkelä authored
      In commit 7a4fbb55 (MDEV-25105)
      the innochecksum option --write (-w) was removed altogether.
      It should have been made a Boolean option, so that old data files
      may be converted to a format that is compatible with
      innodb_checksum_algorithm=strict_crc32 by executing the following:
      
      innochecksum -n -w ibdata* */*.ibd
      
      It would be better to use an older-version innochecksum
      for such a conversion, so that page checksums will be validated
      before updating the checksum.
      
      It never was possible for innochecksum to convert files to the
      innodb_checksum_algorithm=full_crc32 format that is the default
      for new InnoDB data files.

      MDEV-27234: Data dictionary recovery was not READ COMMITTED · 8f8ba758
      Marko Mäkelä authored
      This also fixes MDEV-20198: Instant ALTER TABLE is not crash safe
      
      InnoDB dictionary recovery wrongly used the READ UNCOMMITTED isolation
      level, causing some mismatch. For example, if a table was renamed or
      replaced in a transaction, according to READ UNCOMMITTED the table might
      not exist at all.
      
      We implement READ COMMITTED isolation level for accessing the dictionary
      tables SYS_TABLES, SYS_COLUMNS, SYS_INDEXES, SYS_FIELDS, SYS_VIRTUAL,
      SYS_FOREIGN, SYS_FOREIGN_COLS. For most of these tables, no secondary
      index exists. For the secondary indexes (on SYS_TABLES.ID,
      SYS_FOREIGN.FOR_NAME, SYS_FOREIGN.REF_NAME), we will always look up
      the primary key in the clustered index and check if the record actually
      is a committed version.
      
      dict_check_sys_tables(): Recover tablespaces also from delete-marked
      committed records, so that if a matching .ibd file exists, it will
      be removed by fil_delete_tablespace() when the committed delete-marked
      SYS_INDEXES record of the clustered index is purged
      in row_purge_remove_clust_if_poss_low().
      
      fil_ibd_open(): Change the Boolean parameter "validate" to a ternary
      one, to suppress error messages when the file might not exist.
      It is possible that a .ibd file was deleted and the server shut down
      before the SYS_INDEXES and SYS_TABLES records were purged. Hence, if
      dict_check_sys_tables() finds a committed delete-marked record,
      we must not complain if the tablespace file is not found.
      On Windows, we msut treat ERROR_PATH_NOT_FOUND (directory not found)
      in the same way as ERROR_FILE_NOT_FOUND. This fixes a few failures where
      a previous test successfully executed DROP DATABASE (and deleted all
      files and the directory), but a committed delete-marked SYS_TABLES
      record had not been purged before server restart.
      
      dict_getnext_system_low(): Do not filter out delete-marked records.
      
      dict_startscan_system(), dict_getnext_system(): Do filter out
      delete-marked records, for accessing the INFORMATION_SCHEMA tables.
      
      dict_sys_tables_rec_read(): Return the DB_TRX_ID of the committed
      version of the record. This is needed in dict_load_table_low().
      
      dict_load_foreign_cols(), dict_load_foreign(): Add a parameter for
      the current transaction identifier. In some DDL operations, the
      FOREIGN KEY constraints are being loaded from the data dictionary
      before the DDL transaction has been committed. For SYS_FOREIGN
      and SYS_FOREIGN_COLS, we must implement the special case of
      READ COMMITTED that the changes of the uncommitted current transaction
      are visible.
      
      dict_load_foreign(): Validate the table name. We could find a
      SYS_FOREIGN.ID via a committed delete-marked secondary index record
      that does not match the REF_NAME or FOR_NAME of the secondary index record.
      
      dict_load_index_low(): Optionally take the table as a parameter,
      so that table->def_trx_id can be updated in case of a
      committed delete-marked SYS_INDEXES record corresponding
      to DROP INDEX, but not corresponding to an index stub of ADD INDEX.
      
      dict_load_indexes(): Do not update table->def_trx_id
      in case of delete-marked records.
      
      rec_is_metadata(), rec_offs_make_valid(), rec_get_offsets_func(),
      row_build_low(): Relax some assertions. We may now have
      !index->is_instant() even if a metadata record is present in the index.
      Previously, the recovery of instant ADD/DROP COLUMN assumed
      that READ UNCOMMITTED of the data dictionary will be performed.
      Now, we will have a READ COMMITTED copy of the data dictionary
      cache, and a READ UNCOMMITTED copy of the metadata record.
      
      btr_page_reorganize_low(): Correctly update the FIL_PAGE_TYPE
      when rolling back an instant ADD/DROP COLUMN operation.
      
      row_rec_to_index_entry_impl(): Relax some assertions,
      and disallow accessing "extra" fields. This fixes the recovery
      of a crash during an instant ADD COLUMN after a successful
      instant DROP COLUMN, in the test innodb.instant_alter_crash.

      Igor Babaev authored
      This bug affected queries with IN predicates that contain parameter markers
      in the value list. Such queries are executed via prepared statements.
      The problem appeared only if the number of elements in the value list
      was greater than the set value of the system variable
      in_predicate_conversion_threshold.
      
      The patch unconditionally prohibits conversion of an IN predicate to the
      equivalent IN predicand if the value list of the IN predicate contains
      parameters markers.

      MDEV-24667 LOAD DATA INFILE on temporary table not written to slave binlog · 9f4ba624
      Sachin Kumar authored
      Problem: In regular replication, when master binlogged using statement format
      slave might not have written an event to its binary log when the Query
      event aimed at a temporary table.
      Specifically this was observed with LOAD DATA INFILE.
      
      This effect was possible because unlike master slave holds temporary
      tables in its pool and the master side check of existence of a
      temporary table at the format bin-logging decision did not apply.
      
      Solution: replace THD::has_thd_temporary_tables() with
      THD::has_temporary_tables which allows to identify temporary table
      presence on either side.

      MDEV-24845 Oddities around innodb_fatal_semaphore_wait_threshold and global.innodb_disallow_writes · 9b2fa2ae
      sjaakola authored
      This commit adds a mtr test for reproducing a test scenario where despite of
      innodb_disallow_writes blocking, writes to file system can still happen.
      
      The test launches a garbd node, which triggers one of the cluster node to switch to
      SST donor state. In this state, all disk activity should be halted, and e.g.
      innodb_disallow_writes has been set. The test records md5sum aggregate over mariadb
      data directory when the node enters the donor state, and records another md5sum
      when the node leaves the donor state. If there is no IO activity in data directory, these
      hashes should be equal.
      
      For this test, the Donor state processing, has beeen instrumented so that, SST donor thread can be
      stopped when entering the donor state. The test uses this new dbug sync point,
      to control when to record the md5sums.
      
      New SST script was added: wsrep_sst_backup, and garbd uses backup method to lauch the donor
      node to call this script, and to enter in donor state.
      
      The backup script could be later extended as general purpose backup method for the cluster.
      
      This commit fixes also one race condition happening in wsrep_sst_rsync, like this:
      * wsrep_rsync_sst script requests for flush tables,
        and then waits in a loop until mariadbd has created file tables_flushed,
        as confirmation that FLUSH TABLES has completed
      * mariadbd's SST donor thread, wakes for the flush table request and then performs FTWRL,
        and after this it creates the tables_flushed file
      * note that SST script will now continue to startup rsync sending
      * mariadbd's SST donor thread now calls for sst_disallow_writes(),
        so that innodb would setup disk IO blockage, however rsyncing may already be ongoing at this point
      
      This race condition is fixed in this commit, by performing all disk IO blocking before
      creating the tables_flushed file.

      While moving to a prescribed dependencies in MDEV-28011, an error was made
      in the merge. The Ubuntu and Debian supported architectures of rocksdb-tools
      are different and need to be treated as such.
      
      This actually had no effect as our support of mariadb-plugin-rocksdb was never
      different to the distro support of rocksdb-tools. Some notes where added
      to this affect.
      
      There is also nothing to do for Debian sid, and never should be.
      
      The differentiation and grouping of distro codenames is for convenience in
      merging upwards as more dependencies change across distro versions.
      
      The fixing of versions rather than relying on apt-cache to be correct prevents
      unstable changes between releases, and potentially uninstallable packages like
      happened in MDEV-28014.
