Obsoletes #1018

[prescod]

@jstvz

The current test failure is because CCI is on Pydantic 1 while Snowfakery is on Pydantic 2.

Do you want to:

a) upgrade CCI and Snowfakery to Pydantic 2 in a single coordinated release or

b) support Pydantic 1 and 2 simultaneously in Snowfakery so that they can upgrade in a staggered manner?

[prescod]

Obviously b) involves ugly cruft that will need to be removed eventually.

Option (a) is my preference.

@jstvz . Okay, ping me when the time comes if there are challenges on the Snowfakery side. It actually doesn’t thave a lot of Pydantic stuff in it and arguably what it does have should move to the CCI repo because it relates to CCI.

Is there any progress on this PR? We are using snowfakery in our project and would love to update it to pydantic V2 like our other dependencies.

I would be willing to help if that is possible

[kwendel]

@prescod @jstvz is there any progress in merging this? Pydantic V1 is going to be out of support soon, see https://docs.pydantic.dev/2.5/version-policy/

@kwendel Thanks for the reminder. This PR is currently blocked by a dependency on CumulusCI, which also needs a Pydantic V2 upgrade. I'm bumping the priority with the team internally and will update you here.
