2a8381b23c702518c6b1ccbeafee50b9375df0e4 - Add automatic generated fortran support for setting and returning contexts

Tue, 13 Jan 2026 04:45:38 +0000

Add automatic generated fortran support for setting and returning contextsMajor cleanup of the code for setting and returning application (previously called user) contexts - PetscCtx ctx is now the standard for passing in contexts - PetscCtxRt ctx is the standard for passing out contexts, including context destroy routines based on PetscCtxDestroyFnBoth of these are typedef to void*Also removed most use of user and userctx for context arguments now consistently named ctxImproved documentation on PetscCtx and PetscCtxRt and on how to use contexts (including getting them) from Fortran List of files: /petsc/src/mat/impls/aij/mpi/mpiaij.c

421480d92be24cdb9933c60510b8e175c0a8d034 - - Replace MatMissingDiagonal() and MatMarkDiagonals_SeqXXX() with MatGetDiagonalMarkers_SeqXXX()

Sun, 19 Oct 2025 04:43:08 +0000

- Replace MatMissingDiagonal() and MatMarkDiagonals_SeqXXX() with MatGetDiagonalMarkers_SeqXXX() - Mat_SeqXXX->diag is not automatically created during MatAssemblyEnd() saving memory and time - Accessing Mat_SeqXXX->diag now requires the use of MatGetDiagonalMarkers_SeqXXX() except when the current values are known to be correct; for example during numerical factorizations and solves - Mat_SeqXXX->diag is now never shared among matrices; hence the free_diag flag is gone. That was always a risky proposition since any of the owning matrices could chang the values thus making them incorrect for other owners. List of files: /petsc/src/mat/impls/aij/mpi/mpiaij.c
