* prefix ASAN related inline functions asan_Urabe, Shyouhei2019-05-231-9/+9
| | | | requested by Ko1.
* Rename rb_gc_new_location to rb_gc_locationAaron Patterson2019-05-181-2/+2
| | | | | The function will return new or existing locations depending on whether or not the object actually moved, so give it a more appropriate name.
* don't need to sweep rest.Koichi Sasada2019-05-161-1/+1
| | | | | | | | `transient_heap_evacuate()` disables GC using `rb_gc_disable()` to prohibt GC invocation because of new allocation for evacuated memory. However, `rb_gc_disable()` sweep all rest of unswept pages. We don't need to cancel lazy sweep so this patch introduce `rb_gc_disable_no_rest()` which doesn't cancel lazy sweep.
* unpoison header before touchingUrabe, Shyouhei2019-04-261-0/+3
| | | | | | This header is poisoned to detect unintentional buffer overrun. However in this (and forthcoming) function, we are intentionally looking at the header. We have to unpoison before anything.
* fix size of allocated memoryUrabe, Shyouhei2019-04-261-1/+1
| | | | | The size of `ptr` here is not the same as the variable `size`. We were counting the size of header twice.
* mark verify functions non-sanitizableUrabe, Shyouhei2019-04-261-0/+3
| | | | | These functions purposefully read from memory regions potentially not handled well. Should let sanitizers avoid checking them.
* __asan_region_is_poisoned takes void *Urabe, Shyouhei2019-04-261-1/+1
| | | | while heap->obj is a VALUE. A cast should be there.

* rename li_table->ar_table (and related names).ko12018-12-141-2/+2
| | | | | | | | | | | | | | | | | | | * internal.h: rename the following names: * li_table -> ar_table. "li" means linear (from linear search), but we use the word "array" (from data layout). * RHASH_ARRAY -> RHASH_AR_TABLE. AR_TABLE is more clear. * rb_hash_array_* -> rb_hash_ar_table_*. * RHASH_TABLE_P() -> RHASH_ST_TABLE_P(). more clear. * RHASH_CLEAR() -> RHASH_ST_CLEAR(). * hash.c: rename "linear_" prefix functions to "ar_" prefix. * hash.c (linear_init_table): rename to ar_alloc_table. * debug_counter.h: rename obj_hash_array to obj_hash_ar. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66390 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* adopt sanitizer APIshyouhei2018-11-061-0/+14
| | | | | | | | These APIs are much like <valgrind/memcheck.h>. Use them to fine-grain annotate the usage of our memory. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65573 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* support theap for T_HASH. [Feature #14989]ko12018-10-301-6/+20
| | | | | | | | | | | | | | | | | * 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 <tacingiht@gmail.com> and refined by ko1. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65454 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* support theap for T_STRUCT.ko12018-10-301-10/+10
| | | | | | | * struct.c: members memory can use theap. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65452 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* support theap for T_OBJECT.ko12018-10-301-6/+14
| | | | | | | | | | * variable.c: now instance variable space has theap supports. obj_ivar_heap_alloc() tries to acquire memory from theap. * debug_counter.h: add some counters for theap. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65451 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* introduce TransientHeap. [Bug #14858]ko12018-10-301-0/+834
* transient_heap.c, transient_heap.h: implement TransientHeap (theap). theap is designed for Ruby's object system. theap is like Eden heap on generational GC terminology. theap allocation is very fast because it only needs to bump up pointer and deallocation is also fast because we don't do anything. However we need to evacuate (Copy GC terminology) if theap memory is long-lived. Evacuation logic is needed for each type. See [Bug #14858] for details. * array.c: Now, theap for T_ARRAY is supported. ary_heap_alloc() tries to allocate memory area from theap. If this trial sccesses, this array has theap ptr and RARRAY_TRANSIENT_FLAG is turned on. We don't need to free theap ptr. * ruby.h: RARRAY_CONST_PTR() returns malloc'ed memory area. It menas that if ary is allocated at theap, force evacuation to malloc'ed memory. It makes programs slow, but very compatible with current code because theap memory can be evacuated (theap memory will be recycled). If you want to get transient heap ptr, use RARRAY_CONST_PTR_TRANSIENT() instead of RARRAY_CONST_PTR(). If you can't understand when evacuation will occur, use RARRAY_CONST_PTR().
