Comments on: MySQL QA Episode 10: Reproducing and Simplifying: How to get it Right https://www.percona.com/blog/mysql-qa-episode-10-reproducing-simplifying-get-right/ Wed, 07 Aug 2019 13:18:30 +0000 hourly 1 https://wordpress.org/?v=6.5.2 By: Roel Van de Paar https://www.percona.com/blog/mysql-qa-episode-10-reproducing-simplifying-get-right/#comment-10965621 Thu, 26 Nov 2015 06:00:55 +0000 https://www.percona.com/blog/?p=30764#comment-10965621 @Shahriyar the _run and _run_pquery call the mysql client and the pquery client respectively, and INFILE is passed to them. pquery-run.sh itself is used for the overall run, whereas these scripts are generated by reducer, per-trial (i.e. the trials as created by pquery-run.sh/pquery-prep-red.sh).

@All, please note we have moved percona-qa to GitHub:
https://github.com/Percona-QA/percona-qa

To clone it, use:
$ sudo yum install git
$ cd ~
$ git clone https://github.com/Percona-QA/percona-qa.git

reducer.sh was also put directly into this repository (and it is maintained there), so *no* need anymore to separately fetch lp:randgen.

So the steps we should take for reproducing are:
1. 14xxx_init
2.14xxx_start
3. 14xxx_cl -> for checking it is up or not
4. 14xxx_run or (run_pquery)
5. 14xxx_gdb
6. 14xxx_parse_core

So 14xxx_run.sh is just running generated SQL file as input file using mysql client:
${MYBASE}/bin/mysql -uroot –binary-mode –force -S/dev/shm/1440150447/socket.sock is a binary file]

It is calling pquery-run.sh and assigns 1440150447.sql as INFILE? (INFILE=${SCRIPT_PWD}/pquery/5.7.7.sql)
