Support process plists, for greater GNU compatibility. src/ChangeLog addition: 2010-09-02 Aidan Kehoe <kehoea@parhasard.net> * process.c (process_getprop, process_putprop, process_remprop) (process_plist, process_setplist, reinit_process_early): Add functions to modify a process's property list. * process-slots.h (MARKED_SLOT): Add a plist slot. * fns.c (Fobject_setplist): New function, analogous to #'setplist, but more general. Update the documentation in the other plist functions to reflect that processes now have property lists. * emacs.c (main_1): Call reinit_process_early(), now processes have plist methods that need to be initialised. * symbols.c (reinit_symbol_objects_early): Fsetplist is the named setplist method for symbols. lisp/ChangeLog addition: 2010-09-02 Aidan Kehoe <kehoea@parhasard.net> * obsolete.el (process-get): Make #'process-get, #'process-put, #'process-plist, #'set-process-plist available as aliases to the more general functions #'get, #'put, #'object-plist, #'object-setplist, for GNU compatibility.
