Security Policy Violation
Project is out of compliance with Binary Artifacts policy: binaries present in source code

Rule Description
Binary Artifacts are an increased security risk in your repository. Binary artifacts cannot be reviewed, allowing the introduction of possibly obsolete or maliciously subverted executables. For more information see the Security Scorecards Documentation for Binary Artifacts.

Remediation Steps
To remediate, remove the generated executable artifacts from the repository.

Artifacts Found

• mysql-test/std_data/bug21542698.dat
• mysql-test/std_data/parts/t1_blackhole.par
• mysql-test/std_data/parts/t575.par

Additional Information
This policy is drawn from Security Scorecards, which is a tool that scores a project's adherence to security best practices. You may wish to run a Scorecards scan directly on this repository for more details.

Allstar has been installed on all Google managed GitHub orgs. Policies are gradually being rolled out and enforced by the GOSST and OSPO teams. Learn more at http://go/allstar

This issue will auto resolve when the policy is in compliance.

The server crashes when doing the following:

CREATE TABLE t(i int,
           p PROTOBUF 'message M {  
                        optional int64 i = 1;
                        message P { repeated int64 iarr = 1; repeated string sarr = 2; }
                        repeated P inner = 2;
}');

INSERT INTO t VALUES(1, 'i: 1 inner { iarr: [1,2,3] } ');

SELECT p[inner.iarr] FROM t;

It would be nice to have a wiki page that shows you how to actually use the protobuf feature. For example how do you create a table with a protobuf column, how do you SELECT protobuf subfields etc.

Hi,
I did as the README file says:
After step 9:
Initialize mysqld:
./mysqld --initialize-insecure --pid-file=./mysql.pid --basedir=. --datadir=./datadir --tmpdir=$HOME/mysql-run/tmpdir --socket=$HOME/mysql-run/mysqld.sock
step 10:
Run mysqld:
./mysqld --pid-file=./mysql.pid --basedir=. --datadir=./datadir --tmpdir=$HOME/mysql-run/tmpdir --socket=$HOME/mysql-run/mysqld.sock

I got a problem here at step 11:
Open another terminal and connect to mysqld:
~/tools/mysql-protobuf/bin/client/mysql -u root -S ~/mysql-run/mysqld.sock
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/home/weiwu/mysql-run/mysqld.sock' (2)

There's no such thing called ~/mysql-run/mysqld.sock.

It would be useful to have a step by step compiling and running guide.

We use protobufs in blob columns without native support like this, we have a mariadb installation instead of mysql. Would love if this ported into MariaDB 10.* as well.
