Agenda

Present:

Apologies:

CW: Root in Docker

https://github.com/firedrakeproject/firedrake/pull/4104

Seems to work fairly well. I have tested with a number of downstream packages.

CW: Remove part of CI

https://github.com/firedrakeproject/firedrake/pull/4086

JHC: Various adjoint fixes

1. #4126 Ensure Function.subfunctions is always taped. Currently, subfunctions are not taped if they are first accessed before annotation is enabled. This PR corrects that and adds a test.

2. #4128 Variational solver should either complain if bounds are passed to solve, or remove them from the kwargs if they are None. Merged.

3. #4130 Only pass solver_parameters to the adjoint solver once, and make sure it's the one processed by OptionsManager.

Merge PRs

Note that PRs put in this section should either be trivial or already have been reviewed. Discussion-worthy PRs should be separate agenda items.

CW: #4083

IM: FIAT #134
