make characteristics (and SHOW) work right, we had to separate the old
definition blob in the mysql.proc table into separate fields for parameters,
return type, and body, and handle the characteristics (like SQL SECURITY)
separately... and then reassemble the CREATE string for parsing, of course.
This is rather ugly, mostly the parser bit. (Hopefully that will be better
with the new parser.)
Docs/sp-imp-spec.txt:
Separated the definitions string of the procedure into different columns
in the mysql.proc schema.
mysql-test/r/sp.result:
New characteristics tests.
mysql-test/t/sp.test:
New characteristics tests.
scripts/mysql_create_system_tables.sh:
Separated the definitions string of the procedure into different columns
in the mysql.proc schema.
scripts/mysql_fix_privilege_tables.sql:
Separated the definitions string of the procedure into different columns
in the mysql.proc schema.
sql/sp.cc:
Separated the definitions string of the procedure into different columns.
Rewrote much of the code related this (have a assemble the definition
string from its different parts now) and the way characteristics are now
handled, in order to make ALTER actually work.
sql/sp.h:
Changed prototypes.
sql/sp_head.cc:
Rewrote much of the code related to the new mysql.proc schema with separate
definition fields (have to assemble the definition string from its different
parts now) and the way characteristics are now handled, in order to make ALTER
actually work.
sql/sp_head.h:
Separated the different parts of the definition strings: name, parameters,
return type (for functions) and body.
sql/sql_yacc.yy:
Separated the different parts of the definition strings: name, parameters,
return type (for functions) and body.
This is ugly and messy; hopefully there's a more elegant way to do this
when the new parser is installed.
