fuzz_debug_platform's Introduction

SqlDebug

Toy Arount with It by Docker Compose

You should install Docker Compose on your computer first.

$ git clone https://github.com/fuzzdebugplatform/docker-compose.git
$ cd docker-compose
$ docker-compose up -d
Creating docker-compose_pltform_1 ... done
Creating docker-compose_tw_1      ... done
Creating docker-compose_mysql_1   ... done

The test above is about window functions, with yy file exampleyy/windows.yy.

You can use docker logs -f to see test process:

$ docker logs docker-compose_pltform_1
2019/12/17 11:49:35 staring prepare data in db
2019/12/17 11:49:53 prepare data in db ok
2019/12/17 11:49:53 tidb statistic funtion open ok
2019/12/17 11:49:53 starting generate query
2019/12/17 11:50:04 fuzz ok

When you see "fuzz ok", you can open localhost:43000 to see analysis（you can alse open this page in advance, but you'd better flush the page after fuzz ok）:

If you want to rerun it, please clear them first:

$ docker-compose stop
$ docker-compose rm

Run with Binary

First, you should wrap the tidb version you are interesting with tidb-wrapper
config tidb source dir in config/config.go(must consistent with wrapped tidb)

var defaultConf = Config{
	TiDBSourceDir:        "/home/dqyuan/append/language/Go/projects/hackthon/tidb-bad/",
	TiDBTraceServerAddr:  "http://localhost:43222/trace/",
	TopN:                 10000,
	FailureRateThreshold: 0.7,
}

start a wrapped tidb

tidb-bad-wrapper$ ./bin/tidb-server -path testdb

start a normal tidb (another version)

tidb-good$ ./bin/tidb-server -P 4001 -path testdb

build web page

cd web
yarn run build

run test

./bin/platform -Y exampleyy/subquery_test.yy --dsn1 "root:@tcp(127.0.0.1:4000)/randgen"  --dsn2 "root:@tcp(127.0.0.1:4001)/randgen" -Q 100 --debug -W "web/build"

visit localhost:3000 to see analysis.
