Bug #32124: crash if prepared statements refer to variables in the where clause The code to get read the value of a system variable was extracting its value on PREPARE stage and was substituting the value (as a constant) into the parse tree. Note that this must be a reversible transformation, i.e. it must be reversed before each re-execution. Unfortunately this cannot be reliably done using the current code, because there are other non-reversible source tree transformations that can interfere with this reversible transformation. Fixed by not resolving the value at PREPARE, but at EXECUTE (as the rest of the functions operate). Added a cache of the value (so that it's constant throughout the execution of the query). Note that the cache also caches NULL values. Updated an obsolete related test suite (variables-big) and the code to test the result type of system variables (as per bug 74). mysql-test/extra/rpl_tests/rpl_insert_id.test: Bug #32124: removed ambiguous testcase mysql-test/r/innodb_data_home_dir_basic.result: Bug #32124: fixed wrong test case mysql-test/r/innodb_flush_method_basic.result: Bug #32124: fixed wrong test case mysql-test/r/ps_11bugs.result: Bug #32124: test case mysql-test/r/ssl_capath_basic.result: Bug #32124: fixed wrong test case mysql-test/r/ssl_cipher_basic.result: Bug #32124: fixed wrong test case mysql-test/r/variables.result: Bug #32124: system vars are shown as such in EXPLAIN EXTENDED, not as constants. mysql-test/suite/rpl/r/rpl_insert_id.result: Bug #32124: removed ambiguous testcase mysql-test/t/ps_11bugs.test: Bug #32124: test case sql/item.cc: Bug #32124: placed the code to convert string to longlong or double to a function (so that it can be reused) sql/item.h: Bug #32124: placed the code to convert string to longlong or double to a function (so that it can be reused) sql/item_func.cc: Bug #32124: moved the evaluation of system variables at runtime (val_xxx). sql/item_func.h: Bug #32124: moved the evaluation of system variables at runtime (val_xxx). sql/set_var.cc: Bug #32124: removed the code that calculated the system variable's value at PREPARE sql/set_var.h: Bug #32124: removed the code that calculated the system variable's value at PREPARE tests/mysql_client_test.c: Bug #32124 : removed the reading of the system variable, because its max length is depended on the system charset and client charset and can't be easily calculated.
