From 779e2a968632a5e73c660307892ca6a868399dfc Mon Sep 17 00:00:00 2001 From: Alexey Kopytov Date: Fri, 21 May 2010 15:23:48 +0400 Subject: Bug #42064: low memory crash when importing hex strings, in Item_hex_string::Item_hex_string The status of memory allocation in the Lex_input_stream (called from the Parser_state constructor) was not checked which led to a parser crash in case of the out-of-memory error. The solution is to introduce new init() member function in Parser_state and Lex_input_stream so that status of memory allocation can be returned to the caller. --- mysql-test/t/error_simulation.test | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'mysql-test/t/error_simulation.test') diff --git a/mysql-test/t/error_simulation.test b/mysql-test/t/error_simulation.test index 7cd16a6bc5a..7a48a2e3231 100644 --- a/mysql-test/t/error_simulation.test +++ b/mysql-test/t/error_simulation.test @@ -46,6 +46,20 @@ SELECT * FROM t1; DROP TABLE t1; +--echo # +--echo # Bug#42064: low memory crash when importing hex strings, in Item_hex_string::Item_hex_string +--echo # + +CREATE TABLE t1(a BLOB); + +SET SESSION debug="+d,bug42064_simulate_oom"; +# May fail with either ER_OUT_OF_RESOURCES or EE_OUTOFMEMORY +--error ER_OUT_OF_RESOURCES, 5 +INSERT INTO t1 VALUES(""); +SET SESSION debug=DEFAULT; + +DROP TABLE t1; + --echo # --echo # End of 5.1 tests --echo # -- cgit v1.2.1
