id_table.h: dummy sentinel

2016-08-06T00:35:33+00:00

* id_table.h (rb_id_table_iterator_result): add dummy sentinel
  member because C standard prohibits a trailing comma.

id_table: const correctness for _size and _memsize

2015-11-02T22:18:32+00:00

This allows us to swap in rb_id_table_memsize for st_memsize
(which takes a "const st_table *") more easily.

It also makes sense to do the same for rb_id_table_size,
too; as the table cannot be altered when accessing size.

* id_table.h (rb_id_table_size): const arg
  (rb_id_table_memsize): ditto
* id_table.c (st_id_table_size): ditto
  (st_id_table_memsize): ditto
  (list_id_table_size): ditto
  (list_id_table_memsize): ditto
  (hash_id_table_size): ditto
  (hash_id_table_memsize): ditto
  (mix_id_table_size): ditto
  (mix_id_table_memsize): ditto

id_table.h: include guard

2015-09-17T08:24:54+00:00

* id_table.h (RUBY_ID_TABLE_H): add include guard.

id_table.h: callback function types

2015-08-26T00:47:10+00:00

* id_table.h (rb_id_table_foreach_func_t): define callback
  function type for rb_id_table_foreach().

* id_table.h (rb_id_table_foreach_values_func_t): ditto for
  rb_id_table_foreach_values().

* id_table.h: introduce ID key table.

2015-08-12T08:43:55+00:00

  [Feature #11420]
  This table only manage ID->VALUE table to reduce overhead of st.
  Some functions prefixed rb_id_table_* are provided.
* id_table.c: implement rb_id_table_*.
  There are several algorithms to implement it.
  Now, there are roughly 4 types:
    * st
    * array
    * hash (implemented by  Yura Sokolov)
    * mix of array and hash
  The macro ID_TABLE_IMPL can choose implementation.
  You can see detailes about them at the head of id_table.c.
  At the default, I choose 34 (mix of list and hash).
  This is not final decision.
  Please report your suitable parameters or
  your data structure.
  * symbol.c: introduce rb_id_serial_t and rb_id_to_serial()
    to represent ID by serial number.
  * internal.h: use id_table for method tables.
  * class.c, gc.c, marshal.c, vm.c, vm_method.c: ditto.
