How to chain cherry-picks

[Christian Gagneraud]

Hi all,

I'm looking at automatically cherry-picking changes from branch A to B
(changes typically use gerrit topics).
I've been experimenting with python-gerrit-api [1] and I can do a
single "initial" cherry-pick. To do the next one, I need to add a
"base" revision to the CherryPickInput [2].
The Documentation says "must be a merged commit or a change revision
on the destination branch", in my case I'm looking for the "change
revision" of the previous CP but can't find it.
Does anyone know how/where to get this piece of infor using the REST API?

Thanks,
Chris

It should be the new sha of the previous cherry-pick (which is a change (revision=1)) , I guess.
