    Added versioning of Maria index · 52cb0c24
    Michael Widenius authored
    Store max_trid in index file as state.create_trid. This is used to pack all transids in the index pages relative to max possible transid for file.
    Enable versioning for transactional tables with index. Tables with an auto-increment key, rtree or fulltext keys are not versioned.
    Changed info->lastkey to type MARIA_KEY. Removed info->lastkey_length as this is now part of info->lastkey
    Renamed old info->lastkey to info->lastkey_buff
    Use exact key lenghts for keys, not USE_WHOLE_KEY
    For partial key searches, use SEARCH_PART_KEY
    When searching to insert new key on page, use SEARCH_INSERT to mark that key has rowid
    
    Changes done in a lot of files:
    - Modified functions to use MARIA_KEY instead of key pointer and key length
    - Use keyinfo->root_lock instead of share->key_root_lock[keynr]
    - Simplify code by using local variable keyinfo instead if share->keyinfo[i]
    - Added #fdef EXTERNAL_LOCKING around removed state elements
    - HA_MAX_KEY_BUFF -> MARIA_MAX_KEY_BUFF (to reserve space for transid)
    - Changed type of 'nextflag' to uint32 to ensure all SEARCH_xxx flags fits into it
    
    .bzrignore:
      Added missing temporary directory
    extra/Makefile.am:
      comp_err is now deleted on make distclean
    include/maria.h:
      Added structure MARIA_KEY, which is used for intern key objects in Maria.
      Changed functions to take MARIA_KEY as an argument instead of pointer to packed key.
      Changed some functions that always return true or false to my_bool.
      Added virtual function make_key() to avoid if in _ma_make_key()
      Moved rw_lock_t for locking trees from share->key_root_lock to MARIA_KEYDEF. This makes usage of the locks simpler and faster
    include/my_base.h:
      Added HA_RTREE_INDEX flag to mark rtree index. Used for easier checks in ma_check()
      Added SEARCH_INSERT to be used when inserting new keys
      Added SEARCH_PART_KEY for partial searches
      Added SEARCH_USER_KEY_HAS_TRANSID to be used when key we use for searching in btree has a TRANSID
      Added SEARCH_PAGE_KEY_HAS_TRANSID to be used when key we found in btree has a transid
    include/my_handler.h:
      Make next_flag 32 bit to make sure we can handle all SEARCH_ bits
    mysql-test/include/maria_empty_logs.inc:
      Read and restore current database; Don't assume we are using mysqltest.
      Don't log use databasename to log. Using this include should not cause any result changes.
    mysql-test/r/maria-gis-rtree-dynamic.result:
      Updated results after adding some check table commands to help pinpoint errors
    mysql-test/r/maria-mvcc.result:
      New tests
    mysql-test/r/maria-purge.result:
      New result after adding removal of logs
    mysql-test/r/maria-recovery-big.result:
      maria_empty_logs doesn't log 'use mysqltest' anymore
    mysql-test/r/maria-recovery-bitmap.result:
      maria_empty_logs doesn't log 'use mysqltest' anymore
    mysql-test/r/maria-recovery-rtree-ft.result:

      maria_empty_logs doesn't log 'use mysqltest' anymore
    mysql-test/r/maria.result:
      New tests
    mysql-test/r/variables-big.result:
      Don't log id as it's not predictable
    mysql-test/suite/rpl_ndb/r/rpl_truncate_7ndb_2.result:
      Updated results to new binlog results. (Test has not been run in a long time as it requires --big)
    mysql-test/suite/rpl_ndb/t/rpl_truncate_7ndb_2-master.opt:
      Moved file to ndb replication test directory
    mysql-test/suite/rpl_ndb/t/rpl_truncate_7ndb_2.test:
      Fixed wrong path to included tests
    mysql-test/t/maria-gis-rtree-dynamic.test:

      New tests for some possible problems
    mysql-test/t/variables-big.test:
      Don't log id as it's not predictable
    mysys/my_handler.c:
      Updated function comment to reflect old code
      Changed nextflag to be uint32 to ensure we can have flags > 16 bit
      Changed checking if we are in insert with NULL keys as next_flag can now include additional bits that have to be ignored.
      Added SEARCH_INSERT flag to be used when inserting new keys in btree. This flag tells us the that the keys includes row position and it's thus safe to remove SEARCH_FIND
      Added comparision of transid. This is only done if the keys actually have a transid, which is indicated by nextflag
    mysys/my_lock.c:
      Fixed wrong test (Found by Guilhem)
    scripts/Makefile.am:
      Ensure that test programs are deleted by make clean
    sql/rpl_rli.cc:
      Moved assignment order to fix compiler warning
    storage/heap/hp_write.c:

    storage/maria/Makefile.am:
      Remove also maria log files when doing make distclean
    storage/maria/ha_maria.cc:
      Use 'file->start_state' as default state for transactional tables without versioning
      At table unlock, set file->state to point to live state. (Needed for information schema to pick up right number of rows)
      In ha_maria::implicit_commit() move all locked (ie open) tables to new transaction. This is needed to ensure ha_maria->info doesn't point to a deleted history event.
      Disable concurrent inserts for insert ... select and table changes with subqueries if statement based replication as this would cause wrong results on slave
    storage/maria/ma_blockrec.c:
      Updated comment
    storage/maria/ma_check.c:

      Changed info->lastkey to MARIA_KEY type
      Removed resetting of MARIA_HA variables that have 0 as default value (as info is zerofilled)

      Check on open that state.create_trid is correct
      Extend share->base.max_key_length in case of transactional table so that it can hold transid
