-#!/bin/bash

-# This is the script for us to try to cause the TDengine server or client to crash
-#    
-# PREPARATION
-#
-# 1. Build an compile the TDengine source code that comes with this script, in the same directory tree
-# 2. Please follow the direction in our README.md, and build TDengine in the build/ directory
-# 3. Adjust the configuration file if needed under build/test/cfg/taos.cfg
-# 4. Run the TDengine server instance: cd build; ./build/bin/taosd -c test/cfg
-# 5. Make sure you have a working Python3 environment: run /usr/bin/python3 --version, and you should get 3.6 or above
-# 6. Make sure you have the proper Python packages: # sudo apt install python3-setuptools python3-pip python3-distutils
-#
-# RUNNING THIS SCRIPT
-# 
-# This script assumes the source code directory is intact, and that the binaries has been built in the
-# build/ directory, as such, will will load the Python libraries in the directory tree, and also load
-# the TDengine client shared library (so) file, in the build/directory, as evidenced in the env
-# variables below.
-#
-# Running the script is simple, no parameter is needed (for now, but will change in the future).
-#
-# Happy Crashing...

-
-# Due to the heavy path name assumptions/usage, let us require that the user be in the current directory
-EXEC_DIR=`dirname "$0"`
-if [[ $EXEC_DIR != "." ]]
-then
-    echo "ERROR: Please execute `basename "$0"` in its own directory (for now anyway, pardon the dust)"
-    exit -1
-fi
-
-# First we need to set up a path for Python to find our own TAOS modules, so that "import" can work.
-export PYTHONPATH=$(pwd)/../../src/connector/python/linux/python3
-
-# Then let us set up the library path so that our compiled SO file can be loaded by Python
-export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$(pwd)/../../build/build/lib
-
-# Now we are all let, and let's see if we can find a crash. Note we pass all params
