# Some tests that require --error go into sp-error.test
# Tests that require inndb go into sp_trans.test
# Tests that check privilege and security issues go to sp-security.test.
# Tests that require multiple connections, except security/privilege tests,
#   go to sp-thread.
# Tests that uses 'goto' to into sp-goto.test (currently disabled)
# Tests that destroys system tables (e.g. mysql.proc) for error testing
#   go to sp-destruct.
# Tests that require --with-geometry go into sp_gis.test
# Tests that require multibyte character sets, which are not always available,
#   go into separate files (e.g. sp-ucs2.test)

# Test cases for different combinations of condition handlers in nested
# begin-end blocks in stored procedures.
#
# The SQL standard document says:
# "8) If there is a general <handler declaration> and a specific
# <handler declaration> for the same <condition value> in the same scope, then
# only the specific <handler declaration> is associated with that
# <condition value>."

# A general handler declaration has SQLWARNING + SQLEXCEPTION + NOT FOUND.
# A specific handler declaration has SQLSTATE, condition name, or (for MySQL)
# an errno.
#
# So when there are multiple handlers in the same scope, they're all
# applicable, but the most specific handler should be activated. Notice the
# standard's exact words: "in the same scope". A specific handler declaration
# in an outer scope must not be activated instead of a general handler
# declaration in the inner scope. Previously that was not the case in MySQL.
#
# Note also that '02000' is more specific than NOT FOUND; there might be
# other '02xxx' states, even if we currently do not issue them in any
# situation (e.g. '02001').
#
# Thus, in all combinations below an inner handler should be activated.
