accommodate for @ in database portion even if user:pass is present

Versions

• OS: CentOS 7
• Python: 3.6.8
• SQLAlchemy: 1.4.15
• Database: Mysql
• DBAPI: pymysql

When creating_engine, if the password contains special characters, I understand that it is URL Encoding

DB Test IP : 1.1.1.1 PORT: 3306 ID: test PW: test DB Name: test@test

question

1. What should I do if there are special characters in DB Name? DB Name does not appear to be doing separate decoding

742 tokens = components["database"].split("?", 2)
743 components["database"] = tokens[0]

Parsing error on regular expression below when @ is entered in DB Name

re.compile('\n (?P<name>[\w\+]+)😕/\n (?:\n (?P<username>[^:/])\n (?:😦?P<password>.))?\n @)?\n (?:\n (?:\n , re.VERBOSE) {‘name’: ‘mysql+pymysql’, ‘username’: ‘test’, ‘password’: ‘test@1.1.1.1:3306/test’, ‘ipv6host’: None, ‘ipv4host’: ‘test’, ‘port’: None, ‘database’: None}

Mike Bayer has proposed a fix for this issue in the master branch:

URL parsing fixes https://gerrit.sqlalchemy.org/c/sqlalchemy/sqlalchemy/+/2838

That fix broke our engine connection when we use ‘@’ in our password string, we wanted to avoid using urlib parse quote. Anyway to revert that fix?

The classic Percent-encoding should work
