How do you people look at various trees and lists when debugging them ?
Do you
1. use functions from nodes/print.c to print out tree snapshots
2. run the backend under visual debugger (like DDD) and look at things
there
3. memorize everything in binary and work on raw memory image from
/proc/core ;)
4. use some other method
I am currently working on understanding enough of the parse/plan/execute
process to make up a good plan for implementing WITH RECURSIVE ...
SELECT ...
and perhaps GROUP BY ROLLUP(a,b,c) from SQL99 spec and I'm not
proceeding
as fast as I'd like ;-p
Also could anyone recommend any tools for debugging gram.y or is this
also
done mostly by hand even for large grammars ?
