pysolmysql is a set of simple MYSQL client Apis

They are gevent based. They rely on pymysql.

Usage

d_conf = {
    "host": "localhost",
    "port": 3306,
    "database": None,
    "user": "root",
    "password": "root",
    "autocommit": True,
}
        
ar = MysqlApi.exec_n(d_conf, "select user, host from mysql.user;")

for d_record in ar:
    logger.info("user=%s, host=%s", d_record["user"], d_record["host"])

Pool

Now backed by a basic pool implementation, which support underlying backend clusters (mariadb galera for instance)

This basic pool implementation is forked and adapted from :

• https://github.com/laurentL/django-mysql-geventpool-27
• https://github.com/shunsukeaihara/django-mysql-geventpool

Pool max size

Pool max size (default 10) can be specified using

d_conf = {
    "pool_max_size": 10,
    ...
}

Possible backward compatibility issue:

• If the pool is maxed, an exception will be raised

Multiple hosts

Multiple hosts can be addressed in an active/active manner.

Several hosts can be specified using :

• "hosts" list (preferred)

d_conf = {
    "hosts": ["localhost", "127.0.0.1"],
    ...
}

• "host" comma separated list

d_conf = {
    "host": "localhost,127.0.0.1",
    ...
}

• "host" single entry (backward compatible mode)

d_conf = {
    "host": "localhost",
    ...
}

Source code

• We are pep8 compliant (as far as we can, with some exemptions)
• We use a right margin of 360 characters (please don't talk me about 80 chars)
• All unittest files must begin with test_ or Test, should implement setUp and tearDown methods
• All tests must adapt to any running directory
• The whole project is backed by gevent (http://www.gevent.org/)
• We use docstring (:return, :rtype, :param, :type etc), they are mandatory
• We use PyCharm "noinspection", feel free to use them

Requirements

• Debian 10 or greater, x64, Python 3.7

Unittests

To run unittests, you will need:

• mysql installed and running, with root/root credentials
