Description

A previous pycsw build on Windows, pycsw-2.6.0, had no problems connecting to an SQLite3 repo, such as:

database=sqlite:///C:\\ms4w\\apps\\pycsw-2.6.0\\tests\\functionaltests\\suites\\cite\\data\\cite.db

However with master (and obviously many updated libs underneath), with the same connection in the .yml file:

database: 'sqlite:///C:\\ms4w\\apps\\pycsw-git-master\\tests\\functionaltests\\suites\\cite\\data\\cite.db'

caused error of Could not initialize repository. Check server logs and more specifically: TypeError: declarative_base() got an unexpected keyword argument 'bind'

Traceback

Workaround

I noticed that the SQLAlchemy 2.0 release had some changes in regards to declarative_base(), so I uninstalled SQLAlchemy 2.0.34, and installed 1.4.54, and the problem went away.

Environment

• operating system: Windows
• Python version: 3.12.5
• pycsw version: today's master, built from source
• web server
  • testing with CGI, and mod_wsgi (both successful, after workaround here) through Apache
