Wed, 31 Dec 2025 23:26:53 +0000

Remove legacy '+1' allocations in XXXDiagonalScaleLocalSetUp() routines for AIJ and BAIJ parallel matricesThis commit removes '+1's in some memory allocations that are believedto be leftover from long ago to handle corner cases with malloc() callsof size 0, which some implementations would not handle correctly. Thisceased to be an issue long ago.Thanks-to: Pierre Jolivet , Barry Smith List of files: /petsc/src/mat/impls/aij/mpi/mmaij.c

b1f109025f5dcab6e45bb5c0da1899ec72cc9477 - Fix long-standing bug in MatMPIAIJDiagonalScaleLocalSetUp()

Tue, 23 Dec 2025 02:38:12 +0000

Fix long-standing bug in MatMPIAIJDiagonalScaleLocalSetUp()This commit fixes a problem I discovered in October 2017 and then forgot aboutafter some unsuccessful initial attempts to find the problem. The MPIAIJimplementation for MatDiagonalScaleLocalSetUp() was broken when thelocal-to-global mappings in PETSc were refactored to always useblock indices; the MPIAIJ implementation ofMatDiagonalScaleLocalSetUp(), however, used element-wise, not blockindexing, and this was not refactored at the time, as it was overlookeddue to having no test case.My commit finally fixes this; it also fixes several memory leaks in theAIJ and BAIJ implementations of MatDiagonalScaleLocal() which wereoverlooked, again, due to having no test cases.
