Hi!
Now there are a couple of pull requests that I need to have applied in parallel. Any chance of merging some of them? This one is easy, for example. Perhaps the scm-path fix requires some more testing in different environments.

Tx ! Does those fixed also work on linux ?

I would say that this one does, at least. This is due to .to_uri() providing file:/// and, after replacement of file:// we are left with sqlite:////, which is then not recognized as the connection string (too many slashes).

For the others, like path adjustments, I'd appreciate if someone can try out on Linux and provide feedback.

On the other hand, I found that I can just be on a wild code branch, where I merge all the fixes I need at the moment so it's not so urgent. :)

Ref: https://sqlite.org/c3ref/open.html, section URI filename examples.

I'm not sure how to create tests for this.

What puzzles me is that it worked on my Linux as it was before...

Could you try running report_portfolio_value.py directly? This is the one that was failing if run from command-line, without passing any parameters.
It is reading the db file from the settings and returns a file uri for the book_uri parameter.

Btw, this manifests only now that I started using return pathlib.Path(self.database_path).as_uri() for converting a test file location to a book_uri in reports.
You can check on Linux how many slashes come out in the protocol spec for any file path.
