Introduce `RHASH_TABLE_EMPTY_P` function to check size == 0. There are cases that hash has table data even if data is not NULL (in case removed after inserted elements). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66392 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

"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

Generally, it is difficult so C-extension writers should not use them. * array.c: use `RARRAY_PTR_USE_TRANSIENT` if possible. * hash.c: ditto. * enum.c (enum_sort_by): remove `rb_ary_transient_heap_evacuate()` because `RARRAY_PTR_USE` do de-transient. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66165 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

(1-2) free destination memory if src is NULL. (2) clear transient heap flag if src is NULL. [Bug #15358] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66091 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* hash.c: cast from double to unsigned is undefinedshyouhei2018-11-151-1/+3
| | | | | | | | | | | | | | | | | | | | When a negative double is casted into an unsigned type, that operation is undefined (cf: ISO/IEC 9899:1990 section 6.2.9.3). Recent versions of C kindly footnotes that "The remaindering operation performed when a value of integer type is converted to unsigned type need not be performed when a value of real floating type is converted to unsigned type" (cf: ISO/IEC 9899:1999 section 6.3.1.4 footnote 50). So it is a wrong idea to just cast a double to st_data_t. The intention of the code is commented as "mix the actual float value in". It seems we should do a reinterpret_cast and rule out static_cast. Confirmed this changeset does not affect `make benchmark`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65737 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* hash.c: +(-1) is a wrong ideashyouhei2018-11-081-1/+5
| | | | | | | | | | | | | Before this changeset RHASH_ARRAY_SIZE_DEC() was expaneded to include an expression like `RHASH_ARRAY_SIZE+(-1)`. RHASH_ARRAY_SIZE is by definition unsigned int. -1 is signed, of course. Adding a signed and an unsigned value requires the "usual arithmetic conversions" (cf: ISO/IEC 9899:1990 section 6.2.1.5). -1 is converted to 0xFFFF by that. This patch prevents that conversion. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65632 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

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.
