While trying to find a solution for bug #632578, I tried to figure out where it's code supporting MySQL is to see if we can switch Python MySQL packages. The last commit where rdflib/store/MySQL.py appears was its removal: https://github.com/RDFLib/rdflib/commit/6b648548eba75d18209a304624ba6dd0f94855fe#diff-78a20baaffbdab9c0dcd8023f2149562 This commit was first released as version 3.0.0: https://github.com/RDFLib/rdflib/blob/master/CHANGELOG.md#20100513-release-300 Apparently the MySQL code was moved to: https://code.google.com/archive/p/rdfextras/ With Google Code shutting down, it was apparently moved to GitHub: https://github.com/RDFLib/rdfextras But with version 4 everything from that repository incl. SPARQL support was supposedly merged back into https://github.com/RDFLib/rdflib So I looked what package dev-python/mysql-python actually provides: # q list dev-python/mysql-python | grep __init__ [...] /usr/lib64/python2.7/site-packages/MySQLdb/__init__.py [...] It appears that rdflib does not actually use that package: https://github.com/RDFLib/rdflib/search?q=mysqldb So my question: Does dev-python/rdflib-4.2.2 still support MySQL?
