petsc 3.11 patch: VecScatterCreateWithData

[Drew Parsons]

Jed Brown suggested a patch to keep dolfin working with latest PETSc. - #include petscsys.h instead of petscoptions.h - VecScatterCreateWithData instead of VecScatterCreate

It's been applied to Debian builds, it's working fine. Perhaps it might be useful for the jackhale/petsc-3.10 branch?

[Jack Hale]

That branch is already merged on master I think?

[Drew Parsons]

Looks like you're right, the (3,9,0) test is in master.

In that case Jed's patch could be applied directly to master rather than your petsc-3.10 branch.

[Jack Hale]

By my reading, the patch is for upcoming PETSC 3.11? Make a PR on master and I'll get it put in, and into the 2019.1.0 branch.

[Drew Parsons]

That's right. If I remember right the original patch dealt with SNESTEST same as your 3.10 patch. I refreshed the patch for dolfin 2019.1 What's left are the other bits for petsc 3.11. I'll prepare a PR.

[Drew Parsons]

Created PR519. Threw in a couple of other Debian patches, baker's half dozen.

Just a short remark for everyone else who ends up here: dolfin 2019.1 does not compile with petsc 3.11.1 due to the undeclared “VecScatterCreateWithData”. I saw two commits fixing this

Version 2019.1.0.post0 with petsc 3.11.1 compiles fine.

Cheers

[Drew Parsons]

That’s correct, thanks Georg. 2019.1.0.post0 should be considered the final release version.

[Drew Parsons]

The commits have been made, 2019.1.0.post0 is tagged and released. We can close this bug now.
