[Feature #15947]
Closes: https://github.com/ruby/ruby/pull/2246
|
|
|
|
|
|
|
| |
The behavior of `Hash[[nil]] #=> {}` was a bug until 1.9.3, but had been
remained with a warning because some programs depended upon it.
Now, six years passed. We can remove the compatibility behavior.
[Bug #7300]
|
|
|
|
|
|
|
|
|
| |
For example when an array containing objects is a hash key, the contents
of the array may move which can cause the hash value for the array to
change. This commit makes the default `hash` value based off the
object id, so the hash value will remain stable.
Fixes test/shell/test_command_processor.rb

* hash.c (RHASH_AR_TABLE_SIZE_DEC): generally, we need to check all
entries to calculate exact "bound" in ar_table, but if size == 0,
we can clear bound because there are no active entries.

functions directly.

* hash.c: the type of `ar_table_entry::hash` is not a `VALUE`,
but a `st_hash_t`.
Also `st_hash_t` is not a `st_data_t`, but `st_index_t` (same as st.c).

* internal.h: move ar_table def to hash.c because other files
don't need to know implementation of ar_table.

the size_of(ar_table).

* hash.c: separate NULL and EMPTY check functions.
`RHASH_TABLE_EMPTY` function checks NULL table or not,
but it should be named "NULL_P".
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).

* 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.

* include/ruby/ruby.h: de-transient at
`RARRAY_PTR_USE` and `RARRAY_PTR_USE_START`.
Introduce `RARRAY_PTR_USE_TRANSIENT` and
`RARRAY_PTR_USE_START_TRANSIENT` if you don't want to
de-transient an array. 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.

* hash.c (linear_copy): solve two issues on `Hash#replace`.
(1) fix memory leak
(1-1) don't allocate memory if destination already
has a memory area.
(1-2) free destination memory if src is NULL.
(2) clear transient heap flag if src is NULL. [Bug #15358]

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`.

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.

* 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.
