I ran this test multiple times on a recent devstack (Antelope) and could
not reproduce it. Since it's 5 years old I'll close since there have
been a number of changes in the DB code since then. Please re-open if
you see it again.

Title:
bulk creation of security group rules fails StaleDataError
Status in neutron:
Invalid
Bug description:
Concurrently creating (many) security group rules in a security group,
either posting concurrently directly to the api, or by using heat
fails (on queens) with:
Retry wrapper got retriable exception: UPDATE statement on table
'standardattributes' expected to update 1 row(s); 0 were matched. wrapped

StaleDataError: UPDATE statement on table 'standardattributes' expected to

I've written a small script to reproduce this.
https://gist.github.com/jsm222/2b7db15eaebe69111793359c9a585823
Example usages:
python secruletest.py concurrent --auth-url http://127.0.0.1:5000/v3
--username demo --project-name demo --domain-id default --rules-amount 200
or
python secruletest.py heat --rules-amount 200 --file-out /tmp/heat.yaml
The heat template is just written not applied, the first example makes
a security group named NeutronSecurityGroupRuleTest (can be set with
--security-group-name ) and begins posting rules concurrently.
It is reproducible on rdo packstack queens, and also fails on
production environment (Ubuntu based queens)
