Bug #45092: join buffer contains two blob columns one of which is used in the key employed to access the joined table

Date: Mon, 01 Nov 2010 15:15:25 -0000 3272 Roy Lyseng 2010-11-01 Bug#52068: Optimizer generates invalid semijoin materialization plan When MaterializeScan semijoin strategy was used and there were one or more outer dependent tables before the semijoin tables, the scan over the materialized table was not properly reset for each row of the prefix outer tables. Example: suppose we have a join order: ot1 SJ-Mat-Scan(it2 it3) ot4 Notice that this is called a MaterializeScan, even though there is an outer table ahead of the materialized tables. Usually a MaterializeScan has the outer tables after the materialized table, but this is a special (but legal) case with outer dependent tables both before and after the materialized table. For each qualifying row from ot1, a new scan over the materialized table must be set up. The code failed to do that, so all scans after the first one returned zero rows from the materialized table.

Switch from "Disable identical key handling optimization when IndexConditionPushdown is used" approach To an approach where we save/restore index tuple and so can use index condition pushdown.

Analysis: The assert failed because st_select_lex::print() was called for subqueries as follows: Item_subselect::print() -> subselect_single_select_engine::print() -> st_select_lex::print() It was Item_subselect::fix_fields() that set the thd by calling set_thd(), so when this print() was called before fix_fields(), subselect_engine::thd was NULL. Solution: The patch makes all constructors of all subselect_engine classes to take a THD parameter. The default subselect_single_select_engine engine is created early during parse time, in the Item_subselect::init call, so we pass the correct THD object already at this point.

- Make Mrr_ordered_index_reader() save the rowid across scan interruptions Also - Fix compiler warning for setup_buffer_sizes() - Add commented key_copy/key_restore for better handling of a similar issue with index record being destroyed by scan interruption (which causes incorrect evaluation of pushed index condition later on).

Problem : mtr reports test failure because it sees [ERROR] mysqld got exception 0x80000003 ; in the .err file The exception comes from DBUG_EXECUTE_IF (.. abort()) Fix: use DBUG_ABORT instead of abort() - it does not throw any exceptions.
-

The reason for failure is that DBUG_EXECUTE_IF in mi_open() only worked for Unix-formatted file names, due to strstr(name, "/crashed") The fix change strstr() above to strstr(name, "crashed"), to it can work with Windows file names as well.

Reason: inconsistent compilation, federatedx is compiled without SAFEMALLOC flag, while anything else is compiled with SAFEMALLOC. As a consequence, my_hash_init used inside federatedx initialization does not provide correct caller info parameters (file, line) , so they are initialized with whatever is on stack. When info about allocated memory is output in COM_DEBUG command, the server crashes trying to output string starting at 0xcccccccccccccccc. The fix is to remove SAFEMALLOC preprocessor flags from every CMakeLists.txt, except the top-level one. Also, SAFEMALLOC is not defined by default now, instead there is WITH_DEBUG_FULL CMake option which adds -DSAFEMALLOC to C and C++ flags in debug compilation. This option is off by default, because 1) Debug C runtime already has heap debugging builtin with overwrite and leak detection 2)safemalloc considerably slows down the tests. Note also that - SAFEMALLOC is gone in MySQL5.5 - On Windows, heap related overflows can also be found using free pageheap utility (that is also part of application verifier). This is even more efficient if there are no other layers on top of Windows heap allocator, e.g it is most efficient with release version.
