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/snes/tutorials/ex5.c Tue, 13 Jan 2026 04:45:38 +0000

documentation of the line searches (some of the available options were not listed), and consistently list their respective default values- add proper convergence criteria for the secant method in the L2 line search based on ltol and atol (otherwise, the secant method is mostly running for the maximum number of iterations)- fix a small bug in the CP line search, where steptol * lambda was used to check for convergence based on the change of lambda instead of the ltol parameter- rename sneslinesearch->maxstep to sneslinesearch->maxlambda in the options database to be consistent with its purpose in the algorithms- rename SNESLineSearchL2 to SNESLineSearchSecant to better represent its underlying approach List of files: /petsc/src/snes/tutorials/ex5.c Wed, 27 Aug 2025 02:18:34 +0000 Jonas

liked Jed's use of typedef for function prototypes for a couple of reasons1) you don't see immediately that the argument to the function is a function pointer instead of standard variable when looking at source2) you don't see at the exact location in the code the prototype of the function being passed inbut there is something to say for using these typedefs soI've prototyped the change for SNES but slightly differently than what Jed did for TS1) I append the typedef with _Ftn to mark that it is a function (helping to relieve the problem 1 above)2) I made the typedef to be for a function, not a function pointer so it can also be used directly for things likePETSC_EXTERN SNESJacobian_Ftn SNESComputeJacobianDefault;I think the TS usage could be switched to this style without user code breakage, and deprecate the current TS typedefThoughts?Just do SNES the same way as TS and live with less clarity?
