System.databases.add_alias is missing parameters

[epage]

Looking at the LabVIEW API, XNET Database Add Alias seems to have

• CAN FD ISO mode
• default FD baud rate
• ignore application protocol

in addition to default baud rate and filepath of System.databases.add_alias.

I marked this as a breaking-change, depending on how the API gets exposed. There are ways of implementing it without breaking the API.

@lilesj: We should consult with J. Smith regarding this. add_alias has complex underlying implementation/behavior.

Jason,

Can you give your input on this change? Is this something we should do in the python API?

It's not immediately clear to me if this is doable with just the C API, or if we would have to duplicate any implementation logic and state that is potentially being maintained in nixlvapi.dll.

[sjasonsmith]

There isn't any way to do this through the C API right now. C users currently have to interactively add an alias through the database editor, where a dialog will prompt for these values.

I would suggest NOT implementing anything in Python right now (there isn't any good way to do it anyway!). This should be escalated to be resolved in the C interface, at which point it should be exposed through Python.

Talked with @jashnani. We're closing this issue since it is gated on adding the functionality to the C API. If/when these properties are available in the C API, we will revisit this issue.

Change of plan; we're going to leave the issue open in case that helps keep it on our radar, though it will continue to be blocked until the C API supports these properties.
