Apologies:

Description in PR. More fiddly FloatingType details again.

Minutes

JHC: simple fix but involved lots of work to figure it out so there's a long description in the PR.

CW: Add a comment in the code with similar level of detail as the PR description.

CW: self.idx -> self.subfunction_index in FunctionMergeBlock.

#4175 (information in PR summary)

Be warned: be prepared to think hard pip thoughts

Minutes

CW: Proposal: a shim package petsctools to install petsc4py directly from PETSc (as opposed to using pip).

DH: There are problems with a separate PETSc install.

DH: We can pip install petsc4py by specifying the system PETSc dir. For Ubuntu the plan is to install a PPA PETSc (much harder for Mac).

DH: As long as the user can override the specific version, we could by default dynamically figure out the PETSc version.

DH: We need to consider this further. The user should might not get the versions right.

CW: We consider more flexible minimal PETSc requirements/versions.

DH: Firedrake release branch should be as new user friendly as possible.

CW: I'll think some more.

PB: I still need to get the caching interface.

DH: use object id to memoize visited nodes in the tree.
