      Bug#11766310 : 59398: MYSQLDUMP 5.1 CAN'T HANDLE A DASH · a8e6f7c6
      Nirbhay Choubey authored
                     ("-") IN DATABASE NAMES IN ALTER DATABASE.
      
      mysqldump did not quote database name in 'ALTER DATABASE'
      statements in its output. This can further cause a failure
      while loading if database name contains a hyphen '-'.
      
      This happened as, while printing the 'ALTER DATABASE'
      statements, the database name was not quoted.
      
      Fixed by quoting the database name.

      Bug#11765108 (Bug#58036) client utf32, utf16, ucs2 should be disallowed, they crash server · 8a960129
      Alexander Barkov authored
      A separate fix for 5.1 (as 5.1 and 5.5 have seriously
      differged in the related pieces of the code).
      A patch for 5.5 was approved earlier.
      
      Problem: ucs2 was correctly disallowed in "SET NAMES" only,
      while mysql_real_connect() and mysql_change_user() still allowed
      to use ucs2, which made server crash.
      
      Fix: disallow ucs2 in mysql_real_connect() and mysql_change_user().

      Bug#11766675 - 59839: Aggregation followed by subquery yields wrong result · cd4c263d
      Martin Hansson authored
      The loop that was looping over subqueries' references to outer field used a
      local boolean variable to tell whether the field was grouped or not. But the
      implementor failed to reset the variable after each iteration. Thus a field
      that was not directly aggregated appeared to be.
      
      Fixed by resetting the variable upon each new iteration.

      Bug #11752069 (former bug 43152) · ba5b9734
      Jon Olav Hauglid authored
      Assertion `bitmap_is_set_all(&table->s->all_set)' failed in
      handler::ha_reset
      
      This assertion could be triggered if two connections simultaneously
      executed two bitmap test functions on the same bitmap. For example,
      the assertion could be triggered if one connection executed UPDATE
      while a second connection executed SELECT on the same table.
      
      Even if bitmap test functions have read-only semantics and have
      const bitmaps as parameter, several of them modified the internal
      state of the bitmap. With interleaved execution of two such functions
      it was possible for one function to modify the state of the same
      bitmap that the other function had just modified. This lead to an
      inconsistent state and could trigger the assert.
      
      Internally the bitmap uses 32 bit words for storage. Since bitmaps
      can contain any number of bits, the last word in the bitmap may
      not be fully used. A 32 bit mask is maintained where a bit is set
      if the corresponding bit in the last bitmap word is unused.
      The problem was that several test functions applied this mask to
      the last word. Sometimes the mask was negated and used to zero out
      the remainder of the last word and sometimes the mask was used as-is
      to fill the remainder of the last word with 1's. This meant that if
      a function first used the negated mask and another function then
      used the mask as-is (or vice-versa), the first function would then
      get the wrong result.
      
      This patch fixes the problem by changing the implementation of
      9 bitmap functions that modified the bitmap state even if the 
      bitmap was declared const. These functions now preserve the
      internal state of the bitmap. This makes it possible for
      two connections to concurrently execute two of these functions
      on the same bitmap without issues.
      
      The patch also removes dead testing code from my_bitmap.c.
      These tests have already been moved to unittest/mysys/bitmap-t.c.
      Existing test coverage of my_bitmap has been extended.
      
      No MTR test case added as this would require adding several sync
      points to the bitmap functions. The patch has been tested with
      a non-deterministic test case posted on the bug report.

      Fix for bug#11766714 (former bug @59888) "debug assertion when · 7e1cd4ae
      Dmitry Lenev authored
      attempt to create spatial index on char > 31 bytes".
      
      Attempt to create spatial index on char field with length
      greater than 31 byte led to assertion failure on server
      compiled with safemutex support.
      
      The problem occurred in mi_create() function which was called
      to create a new version of table being altered. This function
      failed since it detected an attempt to create a spatial key
      on non-binary column and tried to return an error.
      On its error path it tried to unlock THR_LOCK_myisam mutex
      which has not been not locked at this point. Indeed such an
      incorrect behavior was caught by safemutex wrapper and caused
      assertion failure.
      
      This patch fixes the problem by ensuring that mi_create()
      doesn't releases THR_LOCK_myisam mutex on error path if it was
      not acquired.

      os_compare_and_swap_thread_id() is defined as
      __sync_bool_compare_and_swap(). From the GCC doc:
      
      `bool __sync_bool_compare_and_swap (TYPE *ptr, TYPE oldval TYPE newval, ...)'
        ...
        The "bool" version returns true if the comparison is successful and
        NEWVAL was written.
      
      So it is not possible that the return value is uninitialized, no matter what
      the arguments to os_compare_and_swap_thread_id() are. Probably Valgrind gets
      confused by the implementation of the GCC internal function
      __sync_bool_compare_and_swap().

      >   Example:
      >   CREATE TABLE t1 (i INT, j BIGINT);
      >   INSERT INTO t1 VALUES (1, 2), (2, 2), (3, 2);
      >   SELECT * FROM (SELECT MIN(i) FROM t1
      >   WHERE j = SUBSTRING('12', (SELECT * FROM (SELECT MIN(j) FROM t1) t2))) t3;
      >   DROP TABLE t1;
      >   
      >   4. Derived tables with subquery where subquery
      >      is evaluated before table locking(Bug#54475, Bug#52157)
      >   
      >   Suggested solution is following:
      >   
      >   -Introduce new field LEX::context_analysis_only with the following
      >    possible flags:
      >    #define CONTEXT_ANALYSIS_ONLY_PREPARE 1
      >    #define CONTEXT_ANALYSIS_ONLY_VIEW    2
      >    #define CONTEXT_ANALYSIS_ONLY_DERIVED 4
      >   -Set/clean these flags when we perform
      >    context analysis operation
      >   -Item_subselect::const_item() returns
      >    result depending on LEX::context_analysis_only.
      >    If context_analysis_only is set then we return
      >    FALSE that means that subquery is non-const.
      >    As all subquery types are wrapped by Item_subselect
      >    it allow as to make subquery non-const when
      >    it's necessary.

      >   Bug#39828 : Autoinc wraps around when offset and increment > 1
      >   Auto increment value wraps when performing a bulk insert with
      >   auto_increment_increment and auto_increment_offset greater than
      >   one.
      >   The fix:
      >   If overflow happened then return MAX_ULONGLONG value as an
      >   indication of overflow and check this before storing the
      >   value into the field in update_auto_increment().
