mark an option as deprecated, optionally replacing it with newname Prints a deprecation warning, unless an option is supplied to suppress.

Logically Collective

Input Parameters#

  • oldname - the old, deprecated option

  • newname - the new option, or NULL if option is purely removed

  • version - a string describing the version of first deprecation, e.g. “3.9”

  • info - additional information string, or NULL.

Options Database Key#

  • -options_suppress_deprecated_warnings - do not print deprecation warnings


If newname is provided then the options database will automatically check the database for oldname.

The old call PetscOptionsXXX(oldname) should be removed from the source code when both (1) the call to PetscOptionsDeprecated() occurs before the new call to PetscOptionsXXX(newname) and (2) the argument handling of the new call to PetscOptionsXXX(newname) is identical to the previous call. See PTScotch_PartGraph_Seq() for an example of when (1) fails and SNESTestJacobian() where an example of (2) fails.

Must be called between PetscOptionsBegin() (or PetscObjectOptionsBegin()) and PetscOptionsEnd(). Only the process of MPI rank zero that owns the PetscOptionsItems are argument (managed by PetscOptionsBegin() or PetscObjectOptionsBegin() prints the information If newname is provided, the old option is replaced. Otherwise, it remains in the options database. If an option is not replaced, the info argument should be used to advise the user on how to proceed. There is a limit on the length of the warning printed, so very long strings provided as info may be truncated.
