From 775e10c4007c024981d0b27f5f2e54c8ac54c73d Mon Sep 17 00:00:00 2001 From: Kaz Kylheku Date: Mon, 17 Jun 2024 00:26:08 -0700 Subject: cobj: clone method streamlines copy; structs get copy method. * lib.h (struct cobj_ops): New function pointer, clone. (cobj_ops_init, cobj_ops_init_ex): Add clone argument to macros. * lib.c (seq_iter_cobj_ops): Use copy_iter as the clone operation. (cptr_ops): Use copy_cptr as clone operation. (copy): Replace if statements by check whether COBJ has a clone operation. If so, we use it to copy the object. * struct.h (enum special_slot): New member, copy_m. * struct.c (copy_s): New symbol variable. (special_sym): Associate copy_m enum value with copy symbol. (struct_init): Initialize copy_s with interned symbol. (struct_inst_clone): New static function. (struct_type_ops): Specify no clone operation via null pointer. (struct_inst_ops): Specify struct_inst_clone as clone operation. * arith.c (psq_ops): Indicate no clone operation via null pointer. * buf.c (buf_strm_ops): Likewise. * chksum.c (sha1_ops, sha256_ops, md5_ops): Likewise. * ffi.c (ffi_type_builtin_ops, ffi_type_struct_ops, ffi_type_ptr_ops, ffi_type_enum_ops, ffi_closure_ops, union_ops): Likewise. (carray_borrowed_ops, carry_owned_ops, carray_mmap_ops): Specify copy_carray as clone operation. * gc.c (prot_array_ops): Indicate no clone operation via null pointer. * gzip.c (gzio_ops_rd, gzip_ops_wr): Likewise. * hash.c (hash_iter_ops): Likewise. (hash_ops): Specify copy_hash as clone operation. * parser.c (parser_ops): Indicate no clone operation via null pointer. * rand.c (random_state_clone): New static function. (random_state_ops): Use random_state_clone as clone function. * regex.c (char_set_obj_ops, regex_obj_ops): Indicate no clone operation via null pointer. * socket.c (dgram_strm_ops): Likewise. * stream.c (null-ops, stdio_ops, tail_ops, pipe_ops, dir_ops, string_in_ops, byte_in_ops, strlist_in_ops, string_out_ops, strlist_out_ops, cat_stream_ops, record_adapter_ops): Likewise. * strudel.c (strudel_ops): Likewise. * sysif.c (cptr_dl_ops, opendir_ops): Likewise. * syslog.c (syslog_strm_ops): Likewise. * unwind.c (cont_ops): Likewise. * vm.c (vm_desc_ops, vm_closure_ops): Likewise. * tree.c (tree_ops): Use copy_search_tree for clone operation. (tree_iter_ops): Use copy_tree_iter for clone operation. * genchksum.txr: Changes in chksum.c specified in one place here. * tests/012/oop.tl: Couple of new tests. * txr.1: Documented. --- rand.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) (limited to 'rand.c') diff --git a/rand.c b/rand.c index 7539714b..cd4be17d 100644 --- a/rand.c +++ b/rand.c @@ -69,11 +69,17 @@ val random_state_s, random_state_var_s, random_warmup_s; struct cobj_class *random_state_cls; +static val random_state_clone(val rand_state) +{ + return make_random_state(rand_state, nil); +} + static struct cobj_ops random_state_ops = cobj_ops_init(eq, cobj_print_op, cobj_destroy_free_op, cobj_mark_op, - cobj_eq_hash_op); + cobj_eq_hash_op, + random_state_clone); /* Source: bits from /dev/random on a Linux server */ static rand32_t rand_tab[16] = { -- cgit v1.2.3
