[GNC] get quotes via gnucash-cli for unknown quote source

[sermon_punisher276 at fwdme.de]

Hi,

I've been trying to get quotes via gnucash-cli with the following command:

gnucash-cli --quotes get mysql://<connection-details>

However, I get the following message when executing the command and no quotes are fetched: 'Price retrieval failed: GncQuotes::Fetch called with no commodities.'

All of my quote sources are of type 'Unknown' (tradegate, fondsweb).

When I get the quotes via 'Get Quotes' in the Price Database, the quotes are fetched normally, so it seems to be a problem with the CLI.

After some investigation, I found out 2 things:

1. When switching the quote source for a security to a source that is not Unknown, the CLI is able to fetch that security's quote.

2. When I edit the file libgnucash/engine/gnc-commodity.c and add the tradegate and fondsweb sources to the 'single_quote_sources' variable (thus making them known sources), the CLI is able to fetch all quotes, no more errors.

This leads me to believe that the CLI fetching ignores securities where the quote source is Unknown, whereas the GUI fetches the quotes regardless of the quote source. I was not able to pin down this behavior in the source, but maybe somebody can clarify whether this is the desired behavior for the CLI.

Tested with most recent stable branch and Flatpak version 5.3, F::Q versions 1.54, 1.56 and 1.58, on Ubuntu 22.04.
