      Fix for Valgrind errors when running rt_test and ma_rt_test, and segmentation fault · f89c61f5
      Guilhem Bichot authored
      in ma_rt_test -M (BUG#36321); keyinfo/recinfo/keyseg had non-initialized parts.
      maria_scan() was not wrapped in maria_scan_init()/end() so "ma_rt_test -M" found no rows.
      Preparing for inclusion into ma_test_all-t and ma_test_recovery.pl (still prevented by
      BUG#37307 "Maria: R-tree unit test produces corrupted table").
      
      storage/maria/ma_rt_test.c:
        Some members of keyinfo, recinfo, keyseg had non-initialized parts, led to Valgrind errors,
        and also segmentation fault when running with -M (=BLOCK_RECORD) (BUG#36321).
        We now bzero them like they are in mi_test1.
        Other problems:
        - maria_scan() was not wrapped in maria_scan_init()/end() so "ma_rt_test -M" found no rows.
        - --silent had almost no effect, now it really silences normal output.
        - Some errors were going to stdout, they now go to stderr.
        Added option for testing versioning, to fit well into ma_test_all-t.
      storage/maria/unittest/ma_test_all-t:
        preparing for running ma_rt_test when ma_rt_test remaining bugs are fixed

      Verify that if Maria table is absent or initially empty, CREATE SELECT and INSERT SELECT with enough
      rows cause no logging
      
      mysql-test/include/maria_empty_logs.inc:
        don't assume that mysqltest is the default db
      mysql-test/r/maria-no-logging.result:
        result. Without the optimization of disabling logging in ha_maria::start_bulk_insert(),
        we see 24k instead of 16k, in the cases where the table is empty.

        side effect of change to maria_empty_logs.inc
      mysql-test/t/maria-purge.test:
        maria-purge.test used to fail when run in a group like this "--big t/*maria*.test" because
        SHOW ENGINE MARIA LOGS was influenced by previous tests; deleting logs to fix that.

      Making maria-recover.test work the same with debug and non-debug builds: one error message was specific of
      debug builds and is now removed, left only in non-ha-maria programs.

      sql/sql_insert.cc:
        removing my old idea of disabling transactionality in CREATE SELECT:
        1) it caused bugs because re-enabling (ha_enable_transaction()) causes implicit commit, so in complex cases
        like "CREATE SELECT some_func())", where some_func() would want to insert two rows in another table, and fail on the second row, the implicit commit would commit the inserted row, while it should roll back.
        2) it's not needed anymore, because CREATE SELECT uses bulk insert, and Maria has transactionality disabled by
        bulk insert.
      sql/sql_show.cc:
        This was duplicate code, causing BUG#36104 "INFORMATION_SCHEMA.TABLES shows TRANSACTIONAL=1 twice in CREATE_OPTIONS"

      Limit maria-recover.test to debug builds and non-ps-protocol for now. Reason is that non-debug Maria outputs
      less corruption warnings (to be discussed), and mysqltest eats warnings when in ps-protocol (to be discussed).
      This is temporary until a better fix is decided.

      WL#4374 "Maria - force start if Recovery fails multiple times" · a5bcb63f
      Guilhem Bichot authored
      http://forge.mysql.com/worklog/task.php?id=4374
      new option --maria-force-start-after-recovery-failures=N; number of consecutive recovery failures (failures
      of log reading or recovery processing, anything in [translog_init(),maria_recovery_from_log()])
      is stored in the control file; if at a Maria start they are more than N, logs are removed. This is for automated
      systems which have to run whatever happens. As tables risk staying corrupted, --maria-recover should also
      be used on them: this revision makes maria-recover work (it was disabled).
      Fixed bug in translog_is_log_files(). translog_init() now prints message to error log if failed.
      Removed \0 in the output of SHOW ENGINE MARIA LOGS; removed hard-coded engine name there.
      
      KNOWN_BUGS.txt:
        As option --maria-force-start-after-recovery-failures is added, it corresponds to the wish "we should fix that if this happens etc".
        LOAD INDEX is not ignored since a few weeks. Listed concurrency bugs have been fixed some time ago.
        Recovery of fulltext and GIS indexes works since a few weeks.
      mysql-test/include/maria_make_snapshot.inc:
        configurable prefix in table's name (so far 't' or 't_corrupted')
      mysql-test/include/maria_make_snapshot_for_comparison.inc:

        configurable prefix in table's name (so far 't' or 't_corrupted')
      mysql-test/lib/mtr_report.pl:
        new test maria-recover.test generates expected corruption warnings in the error log. maria-recovery.test's corrupted table is renamed to t_corrupted1 instead of t1.
      mysql-test/r/maria-preload.result:
        result update. maria_pagecache_read* values are similar to the previous version of this file, though a bit bigger
        because using the information_schema and the join leads to some internal maria temp table being used, and thus some
        blocks of it being read.
      mysql-test/r/maria-purge.result:
        engine's name in SHOW ENGINE MARIA LOGS changed.
      mysql-test/r/maria-recover.result:
        result for new test. We see corruption messages at first SELECT and then none at second SELECT, expected.
      mysql-test/r/maria-recovery.result:
        result update
      mysql-test/r/maria.result:
        new variables show up
      mysql-test/t/disabled.def:
        BUG#34911 is not fixed but the test had been made independent of the bug (workaround). A new bug (crash) has popped recently, so it has to stay
        disabled (BUG#35107).
      mysql-test/t/maria-preload.test:

      mysql-test/t/maria-recovery-bitmap.test:
        update for new API of include/maria*.inc
      mysql-test/t/maria-recovery.test:
        update for new API of include/maria*.inc. Corrupted table t1 renamed to t_corrupted1, so that mtr_report.pl
        does not blindly remove all corruption messages for t1 which is
        a common name.
      storage/maria/ha_maria.cc:
        Enabling maria-recover.
        Adding option and global variable --maria_force_start_after_recovery_failures: ha_maria_init()
        calls mark_recovery_start() and mark_recovery_success() to keep track of failed consecutive recoveries
        and remove logs if needed.
        Removed \0 in the output of SHOW ENGINE MARIA LOGS; removed hard-coded engine name there.
      storage/maria/ma_checkpoint.c:
        new prototype
      storage/maria/ma_control_file.c:
        Storing in one byte in the control file, the number of consecutive recovery failures.

      storage/maria/ma_locking.c:
        Need to update open_count on disk at first write and close for transactional tables, like we already did for
        non-transactional tables, otherwise we cannot notice that the table is dubious.
      storage/maria/ma_loghandler.c:
        translog_is_log_files() is made more generic to serve either to search or to delete logs (the latter is
        for --maria-force-start-after-recovery-failures). It also had a bug (always returned FALSE).
      storage/maria/ma_loghandler.h:
        export function because ha_maria::mark_recovery_start() needs it
      storage/maria/ma_recovery.c:
        changing name of maria_recover() to distinguish from the maria-recover option.
      storage/maria/ma_recovery.h:
        changing name of maria_recover() to distinguish from the maria-recover option.
      storage/maria/ma_test_force_start.pl:
        Test of --maria-force-start-after-recovery-failures (and also, to be realistic, of --maria-recover).
        This is standalone because mysql-test-run does not support testing that multiple mysqld restarts expectedly failed.
        I'll have to run it on my machine and also on a Windows machine.
      storage/maria/unittest/ma_control_file-t.c:
        adding recovery_failures to the test

      sql/sql_load.cc:
        Added new argument to ha_end_bulk_insert()
      sql/sql_parse.cc:
        Style fixes
        Avoid goto in common senario
      sql/sql_select.cc:
        When running with purify/valgrind avoid copying structures over themself.  This is not a real bug in itself, but it's a waste of cycles and causes valgrind warnings
      sql/sql_select.h:
        Avoid copying structures over themself.  This is not a real bug in itself, but it's a waste of cycles and causes valgrind warnings
      sql/sql_table.cc:
        Call HA_EXTRA_PREPARE_FOR_DROP if table created by ALTER TABLE is going to be dropped
        Added new argument to ha_end_bulk_insert()
      storage/archive/ha_archive.cc:
        Added new argument to end_bulk_insert()
      storage/archive/ha_archive.h:
        Added new argument to end_bulk_insert()
      storage/federated/ha_federated.cc:
        Added new argument to end_bulk_insert()
      storage/federated/ha_federated.h:
        Added new argument to end_bulk_insert()
      storage/maria/Makefile.am:
        Added ma_state.c and ma_state.h
      storage/maria/ha_maria.cc:
        Versioning of count(*) and checksum
        - share->state.state is now assumed to be correct, not handler->state
        - Call _ma_setup_live_state() in external lock to get count(*)/checksum versioning. In case of
          not versioned and not concurrent insertable table, file->s->state.state contains the correct state information
        
        Other things:
        - file->s -> share
        - Added DBUG_ASSERT() for unlikely case
        - Optimized end_bulk_insert() to not write anything if table is going to be deleted (as in failed alter table)
        - Indentation changes in external_lock becasue of removed 'goto' caused a big conflict even if very little was changed
      storage/maria/ha_maria.h:
        New argument to end_bulk_insert()
      storage/maria/ma_blockrec.c:
        Update for versioning of count(*) and checksum
        Keep share->state.state.data_file_length up to date (not info->state->data_file_length)
        Moved _ma_block_xxxx_status() and maria_versioning() functions to ma_state.c
      storage/maria/ma_check.c:
        Update and use share->state.state instead of info->state
        info->s to share
        Update info->state at end of repair
        Call _ma_reset_state() to update share->state_history at end of repair
      storage/maria/ma_checkpoint.c:
        Call _ma_remove_not_visible_states() on checkpoint to clean up not visible state history from tables
      storage/maria/ma_close.c:
        Remember state history for running transaction even if table is closed
      storage/maria/ma_commit.c:
        Ensure we always call trnman_commit_trn() even if other calls fails. If we don't do that, the translog and state structures will not be freed
      storage/maria/ma_delete.c:
        Versioning of count(*) and checksum:
        - Always update info->state->checksum and info->state->records
      storage/maria/ma_delete_all.c:
        Versioning of count(*) and checksum:
        - Ensure that share->state.state is updated, as here is where we store the primary information
      storage/maria/ma_dynrec.c:
        Use lock_key_trees instead of concurrent_insert to check if trees should be locked.
        This allows us to lock trees both for concurrent_insert and for index versioning.
      storage/maria/ma_extra.c:
        Versioning of count(*) and checksum:
        - Use share->state.state instead of info->state
        - share->concurrent_insert -> share->non_transactional_concurrent_insert
        - Don't update share->state.state from info->state if transactional table
        
        Optimization:
        - Don't flush io_cache or bitmap if we are using FLUSH_IGNORE_CHANGED
      storage/maria/ma_info.c:
        Get most state information from current state
      storage/maria/ma_init.c:
        Add hash table and free function to store states for closed tables
        Install hook for transaction commit/rollback to update history state
      storage/maria/ma_key_recover.c:
        Versioning of count(*) and checksum:
        - Use share->state.state instead of info->state
      storage/maria/ma_locking.c:
        Versioning of count(*) and checksum:
        - Call virtual functions (if exists) to restore/update status
        - Move _ma_xxx_status() functions to ma_state.c
        
        info->s -> share
      storage/maria/ma_open.c:
        Versioning of count(*) and checksum:
        - For not transactional tables, set info->state to point to new allocated state structure.
        - Initialize new info->state_start variable that points to state at start of transaction
        - Copy old history states from hash table (maria_stored_states) first time the table is opened
        - Split flag share->concurrent_insert to non_transactional_concurrent_insert & lock_key_tree
        - For now, only enable versioning of tables without keys (to be fixed in soon!)
        - Added new virtual function to restore status in maria_lock_database)
        
        More DBUG
      storage/maria/ma_page.c:
        Versioning of count(*) and checksum:
        - Use share->state.state instead of info->state
        - Modify share->state.state.key_file_length under share->intern_lock
      storage/maria/ma_range.c:
        Versioning of count(*) and checksum:
        - Lock trees based on share->lock_key_trees
        
        info->s -> share
      storage/maria/ma_recovery.c:
        Versioning of count(*) and checksum:
        - Use share->state.state instead of info->state
        - Update state information on close and when reenabling logging
      storage/maria/ma_rkey.c:
        Versioning of count(*) and checksum:
        - Lock trees based on share->lock_key_trees
      storage/maria/ma_rnext.c:
        Versioning of count(*) and checksum:
        - Lock trees based on share->lock_key_trees
      storage/maria/ma_rnext_same.c:
        Versioning of count(*) and checksum:
        - Lock trees based on share->lock_key_trees
        - Only skip rows based on file length if non_transactional_concurrent_insert is set
      storage/maria/ma_rprev.c:
        Versioning of count(*) and checksum:
        - Lock trees based on share->lock_key_trees
      storage/maria/ma_rsame.c:
        Versioning of count(*) and checksum:
        - Lock trees based on share->lock_key_trees
      storage/maria/ma_sort.c:
        Use share->state.state instead of info->state
        Fixed indentation
      storage/maria/ma_static.c:
        Added maria_stored_state
      storage/maria/ma_update.c:
        Versioning of count(*) and checksum:
        - Always update info->state->checksum and info->state->records
        - Remove optimization for index file update as it doesn't work for transactional tables
      storage/maria/ma_write.c:
        Versioning of count(*) and checksum:
        - Always update info->state->checksum and info->state->records
      storage/maria/maria_def.h:
        Move MARIA_STATUS_INFO to ma_state.h
        
        Changes to MARIA_SHARE:
        - Added state_history to store count(*)/checksum states
        - Added in_trans as counter if table is used by running transactions
        - Split concurrent_insert into lock_key_trees and on_transactional_concurrent_insert.

        Indentation fixes
      storage/maria/trnman.c:
        Added hook 'trnnam_end_trans_hook' that is called when transaction ends
        Added trn->used_tables that is used to an entry for all tables used by transaction
        More DBUG
        Changed return type of trnman_end_trn() to my_bool
        Added trnman_get_min_trid() to get minimum trid in use.
        Added trnman_exists_active_transactions() to check if there exist a running transaction started between two commit id

      WL#3072 - Maria Recovery · c9a82581
      unknown authored
      Recovery of R-tree and fulltext indices.
      Fix for BUG#35551 "Maria: crash in REPAIR TABLE/ENABLE KEYS if using
      repair-with-keycache method".
      Fix for bug (see ma_rt_index.c) where we could have a wrong
      page_link pointer causing wrong memory access during some R-tree
      index insert/delete.
      Making ma_rt_test work again (it had been neglected over time) and
      adding options (record type etc) to prepare it for integration into
      ma_test_all-t (but there is BUG#36321 about "ma_rt_test -M" crash)
      
      
      mysql-test/r/maria.result:
        correct result
      mysql-test/t/maria.test:
        now we get no error
      storage/maria/ma_blockrec.c:
        delete_dir_entry() and delete_head_or_tail() don't use info->keyread_buff.
        ma_get_length() does not change **packet, marking it with 'const' to
        remove some casts in callers of this function. The
        (const uchar**)&header casts will be removed when Monty changes 'header'
        to const uchar*.
        _ma_apply_redo_purge_row_head_or_tail() sets 'buff' from pagecache_read()
        so its initialization was superfluous.
      storage/maria/ma_check.c:
        Fix for BUG#35551 "Maria: crash in REPAIR TABLE/ENABLE KEYS if using repair-with-keycache method"
        (see comment in code)
      storage/maria/ma_create.c:
        FULLTEXT and SPATIAL indices have logging now, they are recoverable.
      storage/maria/ma_delete.c:
        Logging done by _ma_ck_delete() is moved to a function
        (_ma_write_undo_key_delete()), for reusal by R-tree logging.
        _ma_log_delete() is made non-static for same
        reason, and some of its parameters are made pointers to const.
        Removed wrong comment ("Note that for delete key" etc, contradicted by
        code and comment "Log also position to row" a few lines above)
      storage/maria/ma_ft_update.c:
        unneeded cast, comment for future
      storage/maria/ma_key_recover.c:
        Comment about possible deadlock.
        Write bad page to DBUG trace if KEY_OP_CHECK founds bad CRC.
        Support operation KEY_OP_MULTI_COPY.
        When we execute, in UNDO phase, UNDO_KEY_DELETE|INSERT, we must call
        the proper key insertion|deletion depending on if this is R-tree
        or B-tree.
        Explanation of of _ma_[un]lock_key_del() work, maybe useful for
        mortals like me.
      storage/maria/ma_key_recover.h:
        change of prototypes
      storage/maria/ma_loghandler.h:
        New operation which can be stored in REDO_INDEX log records: KEY_OP_MULTI_COPY
      storage/maria/ma_page.c:
        Comments
      storage/maria/ma_pagecache.c:
        typo
      storage/maria/ma_rt_index.c:
        Fix for bug: the page_link pointer in maria_rtree_insert_req()
        could be wrong when we set its 'changed' member; for the solution
        see ma_key_recover.h. It is needed only in cases when we manipulate
        several pages.
        Logging of changes done to pages by key insert/delete.
        maria_rtree_delete()'s main work is moved to a new function
        maria_rtree_real_delete(), which is used by maria_rtree_delete()
        and by applying of UNDO_KEY_INSERT.
      storage/maria/ma_rt_index.h:
        new prototypes and macros for ma_rt_index.c
      storage/maria/ma_rt_key.c:
        Logging of maria_rtree_add_key() and maria_rtree_delete_key().
        When inserting, split is necessary if there is not enough room for key:
        take checksum's occupied space in this calculation.
      storage/maria/ma_rt_key.h:
        new prototypes (those functions need to know the page's id
        because they do logging)
      storage/maria/ma_rt_mbr.c:
        Comments about what the functions change.
      storage/maria/ma_rt_split.c:
        maria_rtree_split_page() needs to know the page's id, because
        it does logging.
        Logging of what a split operation does to the split page (see
        comment of _ma_log_rt_split(): moves of keys inside the page,
        sometimes insertion of the new key, and shrinking of the page)
        and to the new page (receives some keys from split page, and
        sometimes the new key).
      storage/maria/ma_rt_test.c:
        ma_rt_test had been forgotten when maria_rkey() was changed some months ago
        (0->HA_WHOLE_KEY change), and when calls to maria_rnd(,,HA_OFFSET_ERROR)
        were rewritten to maria_scan() calls (which implies maria_scan_init()).
        The 'max_i' change is to adapt to the fact that maria_scan() does
        not return deleted records for BLOCK_RECORD but does so for other formats;
        the initial code assumed a certain number of deleted records would be
        returned, we change it to rather count only non-deleted ones.
        We also add more features to this test, like ma_test1 (the plan
        is to run ma_rt_test in ma_test_all-t):
        options to choose records' format, table checksum, transactions,
        checkpoints, end at specific stages, abort without committing,
        and debug trace.
      storage/maria/ma_test1.c:
        MY_INIT() does my_init().
      storage/maria/ma_write.c:
        Logging done by _ma_ck_write_btree_with_log() is moved to a function
        (_ma_write_undo_key_insert()), for reusal by R-tree logging.
        _ma_log_new() and _ma_log_change() are made non-static for same
        reason. Some parameters of logging functions are made pointers to const.
        If EXTRA_DEBUG_KEY_CHANGES, we now log CRC in _ma_log_change() too
        (better checks, bigger record).
      storage/maria/maria_read_log.c:
        Program takes no arguments, bail out if any, instead of silently discarding them
      storage/myisam/rt_test.c:
        rt_test had been forgotten when mi_rkey() was changed some months ago
        (0->HA_WHOLE_KEY change).
        The 'max_i' change is to make it symmetric with ma_rt_test.c
      mysql-test/r/maria-gis-rtree-dynamic.result:
        correct result
      mysql-test/r/maria-gis-rtree-trans.result:
        correct result
      mysql-test/r/maria-recovery-rtree-ft.result:
        almost correct result (hitting BUG# in the end)
      mysql-test/t/maria-gis-rtree-dynamic.test:
        test R-tree & dynamic row format
      mysql-test/t/maria-gis-rtree-trans.test:
        Test R-tree and page row format and transactional
      mysql-test/t/maria-recovery-rtree-ft-master.opt:
        usual options for recovery testing
      mysql-test/t/maria-recovery-rtree-ft.test:
        test of recovery of R-tree and fulltext indices.

      Fix for ma_test_all-t failure and dbug/tests-t failure on Solaris: · 75c8e2f4
      unknown authored
      on that machine, "perl" calls /usr/local/bin/perl (so this is what
      runs unittest's unit.pl), while some test scripts (ma_test_recovery.pl
      etc) use /usr/bin/perl which seems to either conflict with /usr/local/bin/perl
      or have problems of its own (Perl errors when loading modules).
      Instead we use perl from the PATH. /usr/bin/env seems to be available
      on lots of Unix machines.

      mysql-test/r/maria-gis-rtree.result:
        result is good now, similar to MyISAM's (gis-rtree.result)
      storage/maria/ma_rt_index.c:
        R-tree key-reading code used info->buff as a cache for the next key read,
        but between key read and next key read, there is record read, which
        uses info->buff too. In detail, during a SELECT:
        First key read: maria_rfirst() is called, which calls maria_rtree_find_first() which calls 
        maria_rtree_find_req() which comes here
                if (after_key < last)
                {
                  // ! the list of keys is copied to info->buff
                  // and info->buff is remembered in info->int_keypos
                  info->int_keypos= info->buff;
                  info->int_maxpos= info->buff + (last - after_key);
                  memcpy(info->buff, after_key, last - after_key);
                  info->keyread_buff_used= 0;
                }
        Then record read:
        _ma_read_block_record() (as well as some other functions of
        ma_blockrec.c) overwrites info->buff:
          if (!(buff= pagecache_read(share->pagecache,
                                     &info->dfile, ma_recordpos_to_page(record_pos), 0,
                                     info->buff, share->page_type,
                                     PAGECACHE_LOCK_LEFT_UNLOCKED, 0)))
        So, this has the effect that the keys saved by maria_rtree_find_req() are now lost:
        info->int_keypos now contains a copy of a data page!
        Then maria_rnext_same() runs (to find second row), calls maria_rtree_find_next() which
        does:
          if (!info->keyread_buff_used)
          {
            uchar *key= info->int_keypos;
            while (key < info->int_maxpos)
            {
              if (!maria_rtree_key_cmp(keyinfo->seg,
                                       info->first_mbr_key, key,
                                       info->last_rkey_length, search_flag))
        
        i.e. maria_rtree_key_cmp() is doing comparisons on values it reads from the data page.
        Naturally this is bad and no row is found.
        Origin of the bug: MARIA_HA::keyread_buff is new in Maria.
        Solution: use keyread_buff instead of buff (like _ma_search_next() does),
        in R-tree code. Note that ma_blockrec.c functions also use keyread_buff
        but they all are write-functions, which should not be running close
        to next-key-read. Also note that some ma_rt_index.c functions still
        use info->buff, but they are about writes too.
        Thanks Monty for the idea.
