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/ts/tutorials/ex53.c

cd791dc2c132c70a186d4b461f371a0a6f494201 - Fix PetscOptionsGetViewer() so it works in a thread-safe way

Tue, 21 Nov 2023 22:06:25 +0000

Fix PetscOptionsGetViewer() so it works in a thread-safe wayWhen PetscOptionsGetViewer() returns, for example, PETSC_VIEWER_STDOUT_SELF the same object is sharedby all threads that call PetscOptionsGetViewer(). In the previous code PetscObjectReference() anddereference (via PetscViewerDestroy() where called on the viewer by multiple threads after the viewerwas accessed thus corrupting the object.This branch introduces a PetscOptionsRestoreViewer() that allows not doing the referencing and dereferencingon persistant viewers, thus removing the specific race condition above.Other possible solutions includeUse a lock on each PetscObjectReference/Dereference() just in case they are shared. Could be time consuming so onecould mark each object as either threadshared or independent and only do the locks on threadshared objects. This lowersthe cost but would require more extensive changes to PETSc infrastructure. And I do not know if this shared/not shared modelis what we need in the long run, though it might be.
