      MDEV-25743: Unnecessary copying of table names in InnoDB dictionary · 49e2c8f0
      Marko Mäkelä authored
      Many InnoDB data dictionary cache operations require that the
      table name be copied so that it will be NUL terminated.
      (For example, SYS_TABLES.NAME is not guaranteed to be NUL-terminated.)
      
      dict_table_t::is_garbage_name(): Check if a name belongs to
      the background drop table queue.
      
      dict_check_if_system_table_exists(): Remove.
      
      dict_sys_t::load_sys_tables(): Load the non-hard-coded system tables
      SYS_FOREIGN, SYS_FOREIGN_COLS, SYS_VIRTUAL on startup.
      
      dict_sys_t::create_or_check_sys_tables(): Replaces
      dict_create_or_check_foreign_constraint_tables() and
      dict_create_or_check_sys_virtual().
      
      dict_sys_t::load_table(): Replaces dict_table_get_low()
      and dict_load_table().
      
      dict_sys_t::find_table(): Renamed from get_table().
      
      dict_sys_t::sys_tables_exist(): Check whether all the non-hard-coded
      tables SYS_FOREIGN, SYS_FOREIGN_COLS, SYS_VIRTUAL exist.
      
      trx_t::has_stats_table_lock(): Moved to dict0stats.cc.
      
      Some error messages will now report table names in the internal
      databasename/tablename format, instead of `databasename`.`tablename`.

      Cleanup: Remove the compile-innodb script · 525bf049
      Marko Mäkelä authored
      The InnoDB storage engine is being built by default.
      There is no need to have an unportable script that encourages
      in-source builds and a particular build driver.

      Cleanup: Remove the error code DB_MUST_GET_MORE_FILE_SPACE · 7bdb8d12
      Marko Mäkelä authored
      Ever since MDEV-24589, MDEV-18518 and other recent changes corrected the
      rollback of CREATE and DROP operations, there is no need to crash the
      server if we run out of space during a DROP operation. We can simply
      let the transaction be rolled back.

      Cleanup: Access lower_case_table_names, tdc_size directly · 9eb4ad57
      Marko Mäkelä authored
      dict_sys_t::evict_table_LRU(): Replaces dict_make_room_in_cache() and
      srv_master_evict_from_table_cache().
      
      innobase_get_table_cache_size(): Replaced with direct read of tdc_size,
      in dict_sys_t::evict_table_LRU().
      
      innobase_get_lower_case_table_names(): Replaced with direct reads of
      lower_case_table_names.

      MDEV-25719: stunnel uses "verifyChain" without subject checks · 3246e729
      Julius Goryavsky authored
      Another batch of changes that should make the SST process
      more reliable in all scenarios:
      
       1) Added hostname or CN verification when stunnel is used
          with certificate chain verification (verifyChain = yes);
       2) Added check for the absence of the stunnel utility for
          mtr tests;
       3) Deletion of working files before and after SST is done
          more accurately;
       4) rsync on joiner can be run even if the path to its
          configuration file contains spaces;
       5) More accurate directory creation (for data files and
          for logs);
       6) IST with mysqldump no longer turns off statement logging;
       7) Reset password for mysqldump when password is empty but
          username is specified;
       8) More reliable quoting when generating statements in
          wsrep_sst_mysqldump;
       9) Added explicit generation of 2048-bit Diffie-Hellman
          parameters for sockat < 1.7.3, by analogy with xtrabackup;
      10) Compression parameters for qpress are read from all
          suitable server groups in configuration file, as well as
          from the [sst] and [xtrabackup] groups;
      11) Added a test that checks compression using qpress;
      12) Checking for optional utilities is modified to work even
          if they implemented as built-in shell commands (unlikely
          on real systems, but more reliable).

      Sergei Golubchik authored
      Followup. If the KILL happens - report it as a failure,
      don't eat it up silently. Note that this has to be done after `table_name`
      is populated, so that the error message could show it.

      MDEV-25606: Concurrent CREATE TRIGGER statements mix up in binlog and break replication · acf282c3
      Monty authored
      The bug is that we don't have a a lock on the trigger name, so it is
      possible for two threads to try to create the same trigger at the same
      time and both thinks that they have succeed.
      Same thing can happen with drop trigger or a combinations of create and
      drop trigger.
      
      Fixed by adding a mdl lock for the trigger name for the duration of the
      create/drop.

      Added checking to protect against simultaneous double free in safemalloc · 79d9a725
      Monty authored
      If two threads would call sf_free() / free_memory() at the same time,
      bad_ptr() would not detect this. Fixed by adding extra detection
      when working with the memory region under sf_mutex.
      
      Other things:
      - If safe_malloc crashes while mutex is hold, stack trace printing will
        hang because we malloc is called by my_open(), which is used by stack
        trace printing code. Fixed by adding MY_NO_REGISTER flag to my_open,
        which will disable the malloc() call to remmeber the file name.

      Fixed hang in concurrent DROP TABLE and BACKUP LOCK BLOCK_DDL · 744a5380
      Monty authored
      The problem was that tdc_remove_referenced_share() did not take into
      account that someone could push things into share->free_tables() even
      if there is a MDL_EXCLUSIVE lock on the table.
      This can happen if flush_tables() uses the table cache to flush a
      a non transactional table to disk.

      Fix all warnings given by UBSAN · cc125beb
      Monty authored
      The 'special' cases where we disable, suppress or circumvent UBSAN are:
      - ref10 source (as here we intentionally do some shifts that UBSAN
        complains about.
      - x86 version of optimized int#korr() methods. UBSAN do not like unaligned
        memory access of integers.  Fixed by using byte_order_generic.h when
        compiling with UBSAN
      - We use smaller thread stack with ASAN and UBSAN, which forced me to
        disable a few tests that prints the thread stack size.
      - Verifying class types does not work for shared libraries. I added
        suppression in mysql-test-run.pl for this case.
      - Added '#ifdef WITH_UBSAN' when using integer arithmetic where it is
        safe to have overflows (two cases, in item_func.cc).
      
      Things fixed:
      - Don't left shift signed values
        (byte_order_generic.h, mysqltest.c, item_sum.cc and many more)
      - Don't assign not non existing values to enum variables.
      - Ensure that bool and enum values are properly initialized in
        constructors.  This was needed as UBSAN checks that these types has
        correct values when one copies an object.
        (gcalc_tools.h, ha_partition.cc, item_sum.cc, partition_element.h ...)
      - Ensure we do not called handler functions on unallocated objects or
        deleted objects.
        (events.cc, sql_acl.cc).
      - Fixed bugs in Item_sp::Item_sp() where we did not call constructor
        on Query_arena object.
      - Fixed several cast of objects to an incompatible class!
        (Item.cc, Item_buff.cc, item_timefunc.cc, opt_subselect.cc, sql_acl.cc,
         sql_select.cc ...)
      - Ensure we do not do integer arithmetic that causes over or underflows.
        This includes also ++ and -- of integers.
        (Item_func.cc, Item_strfunc.cc, item_timefunc.cc, sql_base.cc ...)
      - Added JSON_VALUE_UNITIALIZED to json_value_types and ensure that
        value_type is initialized to this instead of to -1, which is not a valid
        enum value for json_value_types.
      - Ensure we do not call memcpy() when second argument could be null.
      
      Other things:
      
      - Changed struct st_position to an OBJECT and added an initialization
        function to it to ensure that we do not copy or use uninitialized
        members. The change to a class was also motived that we used "struct
        st_position" and POSITION randomly trough the code which was
        confusing.
      - Notably big rewrite in sql_acl.cc to avoid using deleted objects.
      - Changed in sql_partition to use '^' instead of '-'. This is safe as
        the operator is either 0 or 0x8000000000000000ULL.
      - Added check for select_nr < INT_MAX in JOIN::build_explain() to
        avoid bug when get_select() could return NULL.
      - Reordered elements in POSITION for better alignment.
      - Changed sql_test.cc::print_plan() to use pointers instead of objects.
      - Fixed bug in find_set() where could could execute '1 << -1'.
      - Added variable have_sanitizer, used by mtr.  (This variable was before
        only in 10.5 and up).  It can now have one of two values:
        ASAN or UBSAN.
      - Moved ~Archive_share() from ha_archive.cc to ha_archive.h and marked
        it virtual. This was an effort to get UBSAN to work with loaded storage
        engines. I kept the change as the new place is better.
      - Added in CONNECT engine COLBLK::SetName(), to get around a wrong cast
        in tabutil.cpp.
      
      Changes that should not be needed but had to be done to suppress warnings
      from UBSAN:
      
      - Added static_cast<<uint16_t>> around shift to get rid of a LOT of
        compiler warnings when using UBSAN.
      - Had to change some '/' of 2 base integers to shift to get rid of
        some compile time warnings.
      
      Fixes:
      
      MDEV-25505 Assertion `old_flags == ((my_flags & 0x10000U) ? 1 : 0)
      fixed (was caused by an old version if this commit).
