Renames rb_id_table_foreach_with_replace to
rb_id_table_foreach_values_with_replace and passes only the value to the
callback. We can use this in GC compaction when we cannot access the
global symbol array.

To fix build failures.

This shall fix compile errors.

Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).

This reverts commits: 10d6a3aca7 8ba48c1b85 fba8627dc1 dd883de5ba
6c6a25feca 167e6b48f1 7cb96d41a5 3207979278 595b3c4fdd 1521f7cf89
c11c5e69ac cf33608203 3632a812c0 f56506be0d 86427a3219 .
The reason for the revert is that we observe ABA problem around
inline method cache. When a cache misshits, we search for a
method entry. And if the entry is identical to what was cached
before, we reuse the cache. But the commits we are reverting here
introduced situations where a method entry is freed, then the
identical memory region is used for another method entry. An
inline method cache cannot detect that ABA.
Here is a code that reproduce such situation:
```ruby
require 'prime'
class << Integer
alias org_sqrt sqrt
def sqrt(n)
raise
end
GC.stress = true
Prime.each(7*37){} rescue nil # <- Here we populate CC
class << Object.new; end
# These adjacent remove-then-alias maneuver
# frees a method entry, then immediately
# reuses it for another.
remove_method :sqrt
alias sqrt org_sqrt
end
Prime.each(7*37).to_a # <- SEGV
```

This is a pure refactoring to reduce copy & paste. Also the new
function is made visible from other parts of the interpreter, to
be used later.
|
| |
|
|
| |
Not used from anywhere.

This commit adds the new method `GC.compact` and compacting GC support.
Please see this issue for caveats:

Because hard to specify commits related to r67479 only.
So please commit again.

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

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 (rb_id_table_foreach_func_t): define callback
function type for rb_id_table_foreach().

rb_id_table_foreach_values().

[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.
