2021-01-05enable constant cache on ractorsKoichi Sasada
constant cache `IC` is accessed by non-atomic manner and there are thread-safety issues, so Ruby 3.0 disables to use const cache on non-main ractors. This patch enables it by introducing `imemo_constcache` and allocates it by every re-fill of const cache like `imemo_callcache`. [Bug #17510] Now `IC` only has one entry `IC::entry` and it points to `iseq_inline_constant_cache_entry`, managed by T_IMEMO object. `IC` is atomic data structure so `rb_mjit_before_vm_ic_update()` and `rb_mjit_after_vm_ic_update()` is not needed.

2020-10-06Prevent objects from moving while iterating the heapAaron Patterson
This iterator uses an st_table, but if objects move the references in the st table won't be updated. This patch just changes the st table to an identity hash. Notes: Merged:

Again, this code is walking the heap. Empty slots can be poisoned, so we need to unpoison before checking the type Notes: Merged:

2020-09-25Return nil when argument to ObjectSpace.internal_class_of is T_IMEMOAlan Wu
The added test case crashes the interpreter because it makes ObjectSpace.internal_class_of return the second VALUE slot of an AST imemo object. The second VALUE slot of `struct rb_ast_struct` is not a VALUE and not a pointer to a Ruby object. Notes: Merged:

It seems almost no internal codes use RHASH_TBL any longer. Why not just eliminate it entirely, so that the macro can be purely ext-only. Notes: Merged:

2020-02-29should not expose hidden object.Koichi Sasada
Hidden object (T_CLASS) can be exposed (BUG). Also rename rb_mInternalObjectWrapper to rb_cInternalObjectWrapper because it is a class.
2020-02-22Introduce disposable call-cache.Koichi Sasada
This patch contains several ideas: (1) Disposable inline method cache (IMC) for race-free inline method cache * Making call-cache (CC) as a RVALUE (GC target object) and allocate new CC on cache miss. * This technique allows race-free access from parallel processing elements like RCU. (2) Introduce per-Class method cache (pCMC) * Instead of fixed-size global method cache (GMC), pCMC allows flexible cache size. * Caching CCs reduces CC allocation and allow sharing CC's fast-path between same call-info (CI) call-sites. (3) Invalidate an inline method cache by invalidating corresponding method entries (MEs) * Instead of using class serials, we set "invalidated" flag for method entry itself to represent cache invalidation. * Compare with using class serials, the impact of method modification (add/overwrite/delete) is small. * Updating class serials invalidate all method caches of the class and sub-classes. * Proposed approach only invalidate the method cache of only one ME. See [Feature #16614] for more details. Notes: Merged:
2020-02-22VALUE size packed callinfo (ci).Koichi Sasada
Now, rb_call_info contains how to call the method with tuple of (mid, orig_argc, flags, kwarg). Most of cases, kwarg == NULL and mid+argc+flags only requires 64bits. So this patch packed rb_call_info to VALUE (1 word) on such cases. If we can not represent it in VALUE, then use imemo_callinfo which contains conventional callinfo (rb_callinfo, renamed from rb_call_info). iseq->body->ci_kw_size is removed because all of callinfo is VALUE size (packed ci or a pointer to imemo_callinfo). To access ci information, we need to use these functions: vm_ci_mid(ci), _flag(ci), _argc(ci), _kwarg(ci). struct rb_call_info_kw_arg is renamed to rb_callinfo_kwarg. rb_funcallv_with_cc() and rb_method_basic_definition_p_with_cc() is temporary removed because cd->ci should be marked.

2019-12-26decouple internal.h headers卜部昌平
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). Notes: Merged:
2019-11-12Revert "Method reference operator"Nobuyoshi Nakada
This reverts commit 67c574736912003c377218153f9d3b9c0c96a17b. [Feature #16275]
2019-09-07Rename NODE_ARRAY to NODE_LIST to reflect its actual use casesYusuke Endoh
and NODE_ZARRAY to NODE_ZLIST. NODE_ARRAY is used not only by an Array literal, but also the contents of Hash literals, method call arguments, dynamic string literals, etc. In addition, the structure of NODE_ARRAY is a linked list, not an array. This is very confusing, so I believe `NODE_LIST` is a better name.

2018-10-30support theap for T_HASH. [Feature #14989]ko1
* hash.c, internal.h: support theap for small Hash. Introduce RHASH_ARRAY (li_table) besides st_table and small Hash (<=8 entries) are managed by an array data structure. This array data can be managed by theap. If st_table is needed, then converting array data to st_table data. For st_table using code, we prepare "stlike" APIs which accepts hash value and are very similar to st_ APIs. This work is based on the GSoC achievement by tacinight <> and refined by ko1. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-05node.h: remove NODE_PRELUDEmame
NODE_PRELUDE contains a `BEGIN` node, a main node, and compile_option. This node is assumed that it must be located immediately under the root NODE_SCOPE, but this strange assumption is not so good, IMO. This change removes the assumtion; it integrates the former two nodes by block_append, and moves compile_option into rb_ast_body_t. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-10-31Use NODE_CASE2 if case expressions don't existyui-knk
When NODE_WHEN is compiled by iseq_compile_each0, the node passed to compile_when is NODE_WHEN (not NODE_CASE). So we can not handle the location of NODE_CASE of case statements which don't have case expressions. e.g. : ``` case; when 1; foo; when 2; bar; else baz; end ``` This commit adds NODE_CASE2, and compiles it by iseq_compile_each0. * compile.c (compile_case): Does not call COMPILE_ when NODE_CASE does not have case expressions. * compile.c (compile_case2): Compile NODE_CASE2 by compile_case2. * compile.c (compile_when): Delete an obsoleted function. * compile.c (iseq_compile_each0): Compile NODE_CASE2. * ext/objspace/objspace.c (count_nodes): Add NODE_CASE2 case. * node.c (dump_node, rb_gc_mark_node): Add NODE_CASE2 case. * node.h (node_type): Add NODE_CASE2. * node.h (NEW_CASE2): Add a macro which generates NODE_CASE2. * parse.y: Generate NODE_CASE2 if case expressions don't exist. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
