Leginon

pymysql can be installed with pip.

For CentOS 6 and python 2.6 use the tested compatible version.

pip install pymysql==0.7.11

For CentOS7 and python 2.7 use the current version

pip install pymysql

For Windows, download and install 2.7.16 and then from cmd.exe

cd C:\Python27\Scripts
pip install pymysql

pymysql is more strict in database structure and gives error when multiple keys are assigned to indexed field.
This created Issue #7753

d6291bcf4 handles missing column in query of a table not yet has the column. In addition, replaced error instances.

We are not yet converted to use this in myami-trunk and future release. But myami-pymysql will be maintained at slightly behind myami-beta in feature.

leginon is now fully converted to use pymysql in myami-3.6. There are still a few appion scripts using the old system.
