The STACK_MIN_SIZE is currently set to 8192, when we actually need (emperically discovered) 9236 bytes to raise an fatal error, on Ubuntu Dapper Drake, libc6 2.3.6-0ubuntu2, Linux kernel 2.6.15-27-686, on x86. I'm taking that as a new lower bound, plus 100B of wiggle-room for sundry word sizes and stack behaviors. The added test verifies in a cross-platform way that there are no gaps between the space that we think we need and what we actually need to report an error. DOCUMENTERS: This also adds "let" to the mysqltest commands that evaluate an argument to expand variables therein. (Only right of the "=", of course.) client/mysqltest.c: Add "let" to the list of mysqltest commands that evaluates its arguments (only the right-hand-side of the equals-sign expression). mysql-test/r/mysqltest.result: Added test to show that mysqltest "let" will evaluate the RHS correctly (and expand the backslash test). mysql-test/t/mysqltest.test: Added test to show that mysqltest "let" will evaluate the RHS correctly (and expand the backslash test). sql/mysql_priv.h: Increase the amount we require to be available for the stack, since experience told us that the previous amount was too little by at least 1044 bytes. mysql-test/r/execution_constants.result: New BitKeeper file ``mysql-test/r/execution_constants.result'' mysql-test/t/execution_constants.test: New BitKeeper file ``mysql-test/t/execution_constants.test'' |
