      MDEV-15114 ASAN heap-use-after-free in mem_heap_dup or dfield_data_is_binary_equal · ab194666
      Monty authored
      The bug was that innobase_get_computed_value() trashed record[0] and data
      in Field_blob::value
      
      Fixed by using a record on the heap for innobase_get_computed_value()

      Add PART_INDIRECT_KEY_FLAG · 831df109
      Monty authored
      This is to mark that a field is indirectly part of a key, which simplifes
      checking if we need to have this field up to date to evaluate a key.
      
      For example:
      CREATE TABLE t1 (a int, b int as (a) virtual,
                       c int as (b) virtual, index(c))
      would mark a and b with PART_INDIRECT_KEY_FLAG.
      c is marked with PART_KEY_FLAG as before.

      MDEV-16209 JSON_EXTRACT in query crashes server. · 5ba6cee0
      Alexey Botchkov authored
      The optimizer can create various item's over the original one,
          so we can't count on the exact item's type inside the comparison.

      MDEV-16087 Inconsistent SELECT results when query cache is enabled · eb77f8cf
      Thirunarayanan Balathandayuthapani authored
      The following conditions will decide the query cache retrieval or
      storing inside innodb:
      
          (1) There should not be any locks on the table.
          (2) Some other trx shouldn't invalidated the cache before the
          transaction started.
          (3) Read view shouldn't exist. If exists then the view
          low_limit_id should be greater than or equal to the transaction that
          invalidates the cache for the particular table.
      
       For read-only transaction: should satisfy  the above (1) and (3)
       For read-write transaction: should satisfy the above (1), (2), (3).
      
       - Changed the variable from query_cache_inv_id to query_cache_inv_trx_id.
      
       - Moved the function row_search_check_if_query_cache_permitted from
          row0sel.h and made it as static function in ha_innodb.cc

      MDEV-16386: Wrong result when pushdown into the HAVING clause of the · ec4fdd57
      Galina Shalygina authored
                  materialized derived table/view that uses aliases is done
      
      The problem appears when a column alias inside the materialized derived
      table/view t1 definition coincides with the column name used in the
      GROUP BY clause of t1. If the condition that can be pushed into t1
      uses that ambiguous column name this column is determined as a column that
      is used in the GROUP BY clause instead of the alias used in the projection
      list of t1. That causes wrong result.
      To prevent it resolve_ref_in_select_and_group() was changed.

      MDEV-16457 mariabackup 10.2+ should default to innodb_checksum_algorithm=crc32 · a79b033b
      Marko Mäkelä authored
      Since MariaDB Server 10.2.2 (and MySQL 5.7), the default value of
      innodb_checksum_algorithm is crc32 (CRC-32C), not the inefficient "innodb"
      checksum. Change Mariabackup to use the same default, so that checksum
      validation (when using the default algorithm on the server) will take less
      time during mariabackup --backup. Also, mariabackup --prepare should be
      a little faster, and the server should read backups faster, because the
      page checksums would only be validated against CRC-32C.

      MDEV-13103 Deal with page_compressed page corruption · 2ca904f0
      Marko Mäkelä authored
      fil_page_decompress(): Replaces fil_decompress_page().
      Allow the caller detect errors. Remove
      duplicated code. Use the "safe" instead of "fast" variants of
      decompression routines.
      
      fil_page_compress(): Replaces fil_compress_page().
      The length of the input buffer always was srv_page_size (innodb_page_size).
      Remove printouts, and remove the fil_space_t* parameter.
      
      buf_tmp_buffer_t::reserved: Make private; the accessors acquire()
      and release() will use atomic memory access.
      
      buf_pool_reserve_tmp_slot(): Make static. Remove the second parameter.
      Do not acquire any mutex. Remove the allocation of the buffers.
      
      buf_tmp_reserve_crypt_buf(), buf_tmp_reserve_compression_buf():
      Refactored away from buf_pool_reserve_tmp_slot().
      
      buf_page_decrypt_after_read(): Make static, and simplify the logic.
      Use the encryption buffer also for decompressing.
      
      buf_page_io_complete(), buf_dblwr_process(): Check more failures.
      
      fil_space_encrypt(): Simplify the debug checks.
      
      fil_space_t::printed_compression_failure: Remove.
      
      fil_get_compression_alg_name(): Remove.
      
      fil_iterate(): Allocate a buffer for compression and decompression
      only once, instead of allocating and freeing it for every page
      that uses compression, during IMPORT TABLESPACE. Also, validate the
      page checksum before decryption, and reduce the scope of some variables.
      
      fil_page_is_index_page(), fil_page_is_lzo_compressed(): Remove (unused).
      
      AbstractCallback::operator()(): Remove the parameter 'offset'.
      The check for it in FetchIndexRootPages::operator() was basically
      redundant and dead code since the previous refactoring.

      MDEV-16300 : remove rocksdb checkpoint created by mariabackup. · ea705862
      Vladislav Vaintroub authored
      Add variable rocksdb_remove_mariabackup_checkpoint.
      If set, it will remove $rocksdb_datadir/mariabackup-checkpoint directory.
      The variable is to be used by exclusively by mariabackup,
      to remove temporary checkpoints.

      MDEV-16367 mariabackup: error: failed to copy enough redo log · dc9c5554
      Marko Mäkelä authored
      log_copying_thread(): Keep copying redo log until the end has been
      reached. (Previously, we would stop copying as soon as
      the first batch of xtrabackup_copy_logfile() returned.)
      
      log_copying: Remove. Use log_copying_running instead.
      
      copy_logfile: Remove. Log copying will now only be invoked from
      2 places: from xtrabackup_backup_func() for the initial batch,
      and from log_copying_thread() until all of the log has been read.
      Use the global variable metadata_to_lsn for determining if the
      final part of the log is being copied.
      
      xtrabackup_copy_log(): Add diagnostic messages for terminating
      the copying. These messages should be dead code, because
      log_group_read_log_seg() should be checking for the same.
      
      xtrabackup_copy_logfile(): Correct the retrying logic.
      If anything was successfully read, process the portion that
      was read. On failure, let the caller close dst_log_file.
      
      io_watching_thread(): Stop throttling during the last phase
      of copying the log (metadata_to_lsn!=0). The final copying
      of the log will now be performed in log_copying_thread().
      
      stop_backup_threads(): Clean up the message about stopping
      the log copying thread.
      
      xtrabackup_backup_low(): Read metadata_to_lsn from the latest
      checkpoint header page, even if it is the first page.
      Let the log_copying_thread take care of copying all of
      the redo log.

      MDEV-16376 ASAN: heap-use-after-free in gcol.innodb_virtual_debug · 8dc70c86
      Marko Mäkelä authored
      After a failed ADD INDEX, dict_index_remove_from_cache_low()
      could iterate the index fields and dereference a freed virtual
      column object when trying to remove the index from the v_indexes
      of the virtual column.
      
      This regression was caused by a merge of
      MDEV-16119 InnoDB lock->index refers to a freed object.
      
      ha_innobase_inplace_ctx::clear_added_indexes(): Detach the
      indexes of uncommitted indexes from virtual columns, so that
      the iteration in dict_index_remove_from_cache_low() can be avoided.
      
      ha_innobase::prepare_inplace_alter_table(): Ignore uncommitted
      corrupted indexes when rejecting ALTER TABLE. (This minor bug was
      revealed by the extension of the test case.)
      
      dict_index_t::detach_columns(): Detach an index from virtual columns.
      Invoked by both dict_index_remove_from_cache_low() and
      ha_innobase_inplace_ctx::clear_added_indexes().
      
      dict_col_t::detach(const dict_index_t& index): Detach an index from
      a column.
      
      dict_col_t::is_virtual(): Replaces dict_col_is_virtual().
      
      dict_index_t::has_virtual(): Replaces dict_index_has_virtual().

      MDEV-13834: Upgrade failure from 10.1 innodb_encrypt_log · 5932a4e7
      Marko Mäkelä authored
      log_crypt_101_read_block(): Mimic MariaDB 10.1, and use the first
      encryption key if the key for the checkpoint cannot be found.
      Redo log encryption key rotation was ultimately disabled
      in MDEV-9422 (MariaDB 10.1.13) due to design issues. So, from
      MariaDB 10.1.13 onwards only one log encryption key should matter.
      
      recv_log_format_0_recover(): Add the parameter 'bool crypt'.
      Indicate when the log cannot be decrypted for upgrade, instead of
      making a possibly false claim that the log requires crash recovery.
      
      init_crypt_key(): Remove extra space from a message.

      Better Link Spacing · 40dc1a68
      gvtek authored
      Just spacing out the links on separate linkes, they were running together
      in a block of text and could be a little hard for some people to
      differentiate where one begins and the next ends. Seems silly, but just
      trying to help in the formatting a bit.

      MDEV-16353 Server crash on query with CTE · b2f86ebd
      Igor Babaev authored
      This bug caused crashes for queries with unreferenced non-recursive
      CTEs specified by unions.It happened because the function
      st_select_lex_unit::prepare() tried to use the value of the field 'derived'
      that could not be set for unferenced CTEs as there was no derived
      table associated with an unreferenced CTE.
