[ruby-core:62575] [ruby-trunk - Feature #9614] ordering of non-Hash items which use st_ internally
From:
nobu@...
Date:
2014-05-14 05:50:22 UTC
List:
ruby-core #62575
Issue #9614 has been updated by Nobuyoshi Nakada.
I suspect that tests for `local_variables` would need fixing too.
----------------------------------------
Feature #9614: ordering of non-Hash items which use st_ internally
https://bugs.ruby-lang.org/issues/9614#change-46719
* Author: Eric Wong
* Status: Open
* Priority: Normal
* Assignee: Yukihiro Matsumoto
* Category: core
* Target version: current: 2.2.0
----------------------------------------
Hi matz, I would like your permission to remove the order preservation from
any or all of the following currently implemented using `st_table`:
* method tables
* global symbols (`Symbol.all_symbols`)
* constant tables
* instance variable tables
* `global_variables` method
* `Thread#keys`
* anything besides the `Hash` class
I am currently working on a patch series to reduce internal memory usage,
so far I have only converted three pieces:
1. method tables (~200K reduction)
2. symbol table (`global_symbols.`{`id_str`,`sym_id`}) (~200K)
3. `frozen_strings` (~100K)
n.b. `frozen_strings` ordering is never exposed to users, so I expect
it to be OK.
Memory reduction is just based on "`ruby -e exit`" (which loads RubyGems);
bigger programs with more methods/symbols will save more memory.
Work-in-progress patches attached (0002 describes implementation details)
