  • Revision #2835:
    • Fix for Bug #612894
    • Support of virtual columns added to maria engine.
  • Revision #2834:
    • Fixed Bug #610890.
    • The CREATE SHOW TABLE command misplaced virtual column specifiers:
      • the AS clause for a virtual column was put before optional
      • character set attributes, not after them as required by the syntax.
  • Revision #2833: [merge]
    • Merge
    • Revision #2826.3.1:
      • Fixed Bug #607177.
      • Due to an invalid check for NULL of the second argument of the Item_func_round items performed in the code of Item_func_round::real_op the function ROUND sometimes could return wrong results.
  • Revision #2832: [merge]
  • Revision #2831: [merge]
    • Merge
    • none Fixed Bug #607168.
    • The command CREATE TABLE AS SELECT erroneously preserved the virtual properties of the virtual fields from the select list.
  • Revision #2830: [merge]
    • Merge
    • Revision #2826.1.1:
      • Fixed Bug #607566.
      • For queries with order by clauses that employed filesort usage of virtual column references in select lists could trigger assertion failures. It happened because a wrong vcol_set bitmap was used for filesort. It turned out that filesort required its own vcol_set bitmap.
      • Made management of the vcol_set bitmaps similar to the management of the read_set and write_set bitmaps.
  • Revision #2829:
  • Revision #2828:
    • Fixed compiler and valgrind warnings
  • Revision #2827:
    • Changed usage statistics to use 64 bit ints instead of 32 for all relevant variables.
    • Fixes Bug #583314 user_statistics - INT overflow
  • Revision #2826: [merge]
    • Merge
    • Revision #2822.2.1:
      • Fixed Bug #604503.
      • If the expression for a virtual column of table contained datetime comparison then the execution of the second query that used this virtual column caused a crash. It happened because the execution of the first query that used this virtual column inserted a cached item into the expression tree. The cached tree was allocated in the statement memory while the expression tree was allocated in the table memory.
      • Now the cached items that are inserted into expressions for virtual columns with datetime comparisons are always allocated in the same mem_root as the expressions for virtual columns. So now the inserted cached items are valid for any queries that use these virtual columns.
  • Revision #2825: [merge]
  • Revision #2824: [merge]
    • Merge patch for ha_rnd_init()
    • Revision #2822.1.1:
      • Fix for Bug #588251: doStartTableScan() result not checked.
      • The issue was that we didn't always check result of ha_rnd_init() which caused a problem for handlers that returned an error in this code.
        • Changed prototype of ha_rnd_init() to ensure that we get a compile warning if result is not checked.
        • Added ha_rnd_init_with_error() that prints error on failure.
        • Checked all usage of ha_rnd_init() and ensure we generate an error message on failures.
        • Changed init_read_record() to return 1 on failure.
  • Revision #2823:
    • Fixed Bug #603186.
    • There were two problems that caused wrong results reported with this bug.
      1. In some cases stored(persistent) virtual columns were not marked in the write_set and in the vcol_set bitmaps.
      2. If the list of fields in an insert command was empty then the values of the stored virtual columns were set to default.
    • To fix the first problem the function st_table::mark_virtual_columns_for_write was modified. Now the function has a parameter that says whether the virtual columns are to be marked for insert or for update.
    • To fix the second problem a special handling of empty insert lists is added in the function fill_record().
  • Revision #2822:
    • Fixed Bug #603654.
    • If a virtual column was used in the ORDER BY clause of a query and some of the columns this virtual column was based upon were not referenced anywhere in the query then the execution of the query could cause an assertion failure.
    • It happened because in this case the bitmap of the columns used for ordering keys was not formed correctly.
  • Revision #2821:
    • Fixed Bug #604549.
    • There was no error thrown when creating a table with a virtual table computed by an expression returning a row.
    • This caused a crash when inserting into the table.
    • Removed periods at the end of the error messages for virtual columns.
    • Adjusted output in test result files accordingly.
  • Revision #2820:
    • Initial import of SpinxSE, with fixes for MariaDB.
  • Revision #2819: [merge]
  • Revision #2818:
    • Fixed Bug #601164.
    • The functions mysql_delete and mysql_update lacked calls of updated_virtual_fields(). This caused wrong results for some DELETEs/UPDATEs.
    • Added test cases for this bug.
  • Revision #2817:
    • Make MariaDB compile with VS 2010
    • Most of the changes are backports from MySQL 5.5. Please note that the 64-bit build fails with VS 2010 and the 32-bit build has problems running mysql-test-run.pl.
    • Added files for compiling with VS 2010 and added them to Makefile.am.
    • ifdef'ed ETIMEDOUT, because it is defined by VS 2010 now
    • Removed not needed /MAP's from cmake files
