Open Source CAI Framework Handles Pen Testing Tasks up to 3,600× Faster Than Humans
CAI is a new open source AI framework that automates penetration testing tasks like scanning and exploitation up to 3,600× faster than humans.
Yoyo-migrations is a database schema migration tool. Database migrations can be written as SQL files or Python scripts.
As your database application evolves, changes to the database schema may be required. Yoyo lets you write migration scripts in raw SQL or Python containing SQL statements to migrate your database schema to a new version.
A simple migration script looks like this:
.. code::python
# file: migrations/0001.create-foo.py
from yoyo import step
step(
"CREATE TABLE foo (id INT, bar VARCHAR(20), PRIMARY KEY (id))",
"DROP TABLE foo",
)
Yoyo manages these database migration scripts, gives you command line tools to apply and rollback migrations, and manages dependencies between migrations.
PostgreSQL, MySQL and SQLite databases are supported. ODBC and Oracle database backends are available (but unsupported).
