# Clean lines from simulator output by:
|
|
# 1) Removing everything up to and including "interaction="
|
|
# 2) Replacing everything from "}:" to the end with a single semicolon
|
|
# 3) Only retaining lines containing CREATE/INSERT/UPDATE/DELETE/DROP (the rest are usually meaningless for debugging)
|

|

# The purpose of this is to transform the interaction plan into a list of executable SQL statements
|

# in cases where:
|
|
# 1. Shrinking the plan failed
|
|
# 2. We know the point at which the simulator failure occurred.

# I use this script like this in the simulator directory:
|
|
# cargo run &> raw_output.txt
|
|
# manually edit out the shrinking parts and the WarGames intro graphics etc and save the file
|
|
# then run:
|
|
# ./clean_interactions.sh raw_output.txt > interactions.sql
|
|
#
|
|
# Usage:
|
|
# clean_interactions.sh INPUT [OUTPUT]
|
|
#
|
|
# If OUTPUT is omitted, the result is written to stdout.
