Introduce explicit stacks for traversing common data types during printing: conses, vectors, records, byte-code, hash-tables and char-tables, all previously traversed using recursion in C. This greatly reduces the risk of crashing Emacs from C stack overflow when printing deeply nested data. * src/print.c (Fprinc, print, PRINT_CIRCLE_CANDIDATE_P): Special-case Fprinc with a plain string argument to eliminate the need for keeping track of print_depth during the preprocessing phase. This also improves performance. (struct print_pp_entry, struct print_pp_stack, ppstack) (grow_pp_stack, pp_stack_push_value, pp_stack_push_values) (pp_stack_empty_p, pp_stack_pop): New stack for preprocessing. (print_preprocess): Make mostly nonrecursive, except for string properties. (enum print_entry_type, struct print_stack_entry) (struct print_stack, prstack, grow_print_stack) (print_stack_push, print_stack_push_vector): New stack for printing. (print_vectorlike, print_object): Make mostly nonrecursive, except for string properties and some less heavily used types. * test/src/print-tests.el (print-deeply-nested): New test. |
