Yusuke Endoh 77bb79b8cf array.c: factor out a complex condition of assert
ARY_SHARED_P and ARY_EMBED_P included:

   assert(!FL_TEST((ary), ELTS_SHARED) || !FL_TEST((ary), RARRAY_EMBED_FLAG)),

The two predicate macros are used in many other assert conditions,
which caused memory bloat during C compilation.
This change factors out the assertion above to a function.
Now gcc consumes 160 MB instead of 250 MB to compile array.c.

Yusuke Endoh 0a16ff9f83 array.c: use assert in macro instead of in a function
The old code lost information of lineno.  Now, an assertion error will
output a correct lineno (but now gcc 8 requires 250 MB, unfortunately).

Yusuke Endoh 3e8d4ff3e5 array.c: factor out `assert(RB_TYPE_P(ary, T_ARRAY))` to a function
The assertion blows up gcc 8 by consuming approx. 1.8 GB memory.
This change reduces the amount of memory required to about 200 MB.

A follow-up of ae750799c1.
2019-07-19 23:41:24 +09:00
Koichi Sasada ae750799c1 Use FL_TEST_RAW() to check flags.
FL_TEST() uses FL_ABLE() which test data types. However,
in array.c we don't need to check it (all of them should be
T_ARRAY), so I changed from FL_TEST() to FL_TEST_RAW() which
does not check FL_ABLE(). Instead of FL_ABLE(), add assertion
to check given object is a T_ARRAY object.

For example, rb_ary_free() becomes slim:

with FL_TEST():

Koichi Sasada 182ae1407b fix shared array terminology.
Shared arrays created by Array#dup and so on points
a shared_root object to manage lifetime of Array buffer.
However, sometimes shared_root is called only shared so
it is confusing. So I fixed these wording "shared" to "shared_root".

* RArray::heap::aux::shared -> RArray::heap::aux::shared_root
* ARY_SHARED() -> ARY_SHARED_ROOT()
* ARY_SHARED_NUM() -> ARY_SHARED_ROOT_REFCNT()

Also, add some debug_counters to count shared array objects.

* ary_shared_create: shared ary by Array#dup and so on.
* ary_shared: finished in shard.
* ary_shared_root_occupied: shared_root but has only 1 refcnt.
  The number (ary_shared - ary_shared_root_occupied) is meaningful.

Jeremy Evans ced640951b Implement Array#minmax
Array#minmax was previous not implemented, so calling #minmax on
array was actually calling Enumerable#minmax.  This is a simple
implementation of #minmax by just calling rb_ary_min and
rb_ary_max, which improves performance significantly.

nobu 10d85b19da Clarify Array#- and Array#difference documentation
Currently we are not explicit enough regarding the potentially confusing
behavior of `Array#-` and `Array#difference` when it comes to duplicate items
within receiver arrays.

Although the original documentation for these methods does use an array with
multiple instance of the same integers, the explanation for the behavior is
actually imprecise.

> removing any items that also appear in +other_ary+

Not only does `Array#-` remove any items that also appear in `other_ary` but
it also remove any instance of any item in `other_ary`.

One may expect `Array#-` to behave like mathematical subtraction or difference
when it doesn't. One could be forgiven to expect the following behavior:

```ruby
[1,1,2,2,3,3,4,4] - [1,2,3,4]
=> [1,2,3,4]
```

In reality this is the result:

```ruby
[1,1,2,2,3,3,4,4] - [1,2,3,4]
=> []
```

I hope that I've prevented this potential confusion with the clarifications
in this change. I can offer this as evidence of likeliness for confusion:
https://twitter.com/olivierlacan/status/1084930269533085696

I'll freely admit I was surprised by this behavior myself since I needed to
obtain an Array with only one instance of each item in the argument array
removed.

tenderlove d46cd60f3c Use a shared array for the `duparray` instruction
In this example code:

```ruby
def foo
  [1, 2, 3, 4]
end
```

The array literal uses a `duparray` instruction. Before this patch,
`rb_ary_resurrect` would malloc and memcpy a new array buffer.  This
patch changes `rb_ary_resurrect` to use `ary_make_partial` so that the
new array object shares the underlying buffer with the array stored in
the instruction sequences.

Before this patch, the new array object is not shared:

```
$ ruby -r objspace -e'p ObjectSpace.dump([1, 2, 3, 4])'
"{\"address\":\"0x7fa2718372d0\", \"type\":\"ARRAY\", \"class\":\"0x7fa26f8b0010\", \"length\":4, \"memsize\":72, \"flags\":{\"wb_protected\":true}}\n"
```

After this patch:

```
$ ./ruby -r objspace -e'p ObjectSpace.dump([1, 2, 3, 4])'
"{\"address\":\"0x7f9a76883638\", \"type\":\"ARRAY\", \"class\":\"0x7f9a758af900\", \"length\":4, \"shared\":true, \"references\":[\"0x7f9a768837c8\"], \"memsize\":40, \"flags\":{\"wb_protected\":true}}\n"

  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.

ko1 312b105d0e introduce TransientHeap. [Bug #14858]
* 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().

nobu d65d5533ab Add difference method to Array
I introduce a `difference` method equivalent to the `-` operator, but
which accept more than array as argument. This improved readability, and
it is also coherent with the `+` operator, which has a similar `concat`
method. The method doesn't modify the original object and return a new
object instead. I plan to introduce a `difference!` method as well.

Tests and documentation are included.

k0kubun ed935aa5be mjit_compile.c: merge initial JIT compiler
which has been developed by Takashi Kokubun <takashikkbn@gmail> as
YARV-MJIT. Many of its bugs are fixed by wanabe <s.wanabe@gmail.com>.

This JIT compiler is designed to be a safe migration path to introduce
JIT compiler to MRI. So this commit does not include any bytecode
changes or dynamic instruction modifications, which are done in original
MJIT.

This commit even strips off some aggressive optimizations from
YARV-MJIT, and thus it's slower than YARV-MJIT too. But it's still
fairly faster than Ruby 2.5 in some benchmarks (attached below).

Note that this JIT compiler passes `make test`, `make test-all`, `make
test-spec` without JIT, and even with JIT. Not only it's perfectly safe
with JIT disabled because it does not replace VM instructions unlike
MJIT, but also with JIT enabled it stably runs Ruby applications
including Rails applications.

I'm expecting this version as just "initial" JIT compiler. I have many
optimization ideas which are skipped for initial merging, and you may
easily replace this JIT compiler with a faster one by just replacing
mjit_compile.c. `mjit_compile` interface is designed for the purpose.

common.mk: update dependencies for mjit_compile.c.

internal.h: declare `rb_vm_insn_addr2insn` for MJIT.

vm.c: exclude some definitions if `-DMJIT_HEADER` is provided to
compiler. This avoids to include some functions which take a long time
to compile, e.g. vm_exec_core. Some of the purpose is achieved in
transform_mjit_header.rb (see `IGNORED_FUNCTIONS`) but others are
manually resolved for now. Load mjit_helper.h for MJIT header.
mjit_helper.h: New. This is a file used only by JIT-ed code. I'll
refactor `mjit_call_cfunc` later.
vm_eval.c: add some #ifdef switches to skip compiling some functions
like Init_vm_eval.

win32/mkexports.rb: export thread/ec functions, which are used by MJIT.

include/ruby/defines.h: add MJIT_FUNC_EXPORTED macro alis to clarify
that a function is exported only for MJIT.

array.c: export a function used by MJIT.
bignum.c: ditto.
class.c: ditto.
compile.c: ditto.
error.c: ditto.
gc.c: ditto.
hash.c: ditto.
iseq.c: ditto.
numeric.c: ditto.

st.c: ditto.
string.c: ditto.
thread.c: ditto.
variable.c: ditto.
vm_backtrace.c: ditto.
vm_insnhelper.c: ditto.
vm_method.c: ditto.

I would like to improve maintainability of function exports, but I
believe this way is acceptable as initial merging if we clarify the
new exports are for MJIT (so that we can use them as TODO list to fix)
and add unit tests to detect unresolved symbols.
I'll add unit tests of JIT compilations in succeeding commits.

* Known issues
  * Code generated by gcc is faster than clang. The benchmark may be worse
    in macOS. Following benchmark result is provided by gcc w/ Linux.
  * Performance is decreased when Google Chrome is running
  * JIT can work on MinGW, but it doesn't improve performance at least
    in short running benchmark.
  * Currently it doesn't perform well with Rails. We'll try to fix this
    before release.

We should fix this.
(At least I know opt_aref is performing badly in JIT and I have an idea
 to fix it. Please wait for the fix.)

nobu 9bc73cd81f array.c: improve operations on small arrays
[Feature #13884]

Reduce number of memory allocations for "and", "or" and "diff"
operations on small arrays

Very often, arrays are used to filter parameters and to select
interesting items from 2 collections and very often these
collections are small enough, for example:

```ruby
SAFE_COLUMNS = [:id, :title, :created_at]

def columns
  @all_columns & SAFE_COLUMNS
end
```

In this patch, I got rid of unnecessary memory allocations for
small arrays when "and", "or" and "diff" operations are performed.

watson1978 d0015e4ac6 Improve performance of implicit type conversion
To convert the object implicitly, it has had two parts in convert_type() which are
  1. lookink up the method's id
  2. calling the method

Seems that strncmp() and strcmp() in convert_type() are slightly heavy to look up
the method's id for type conversion.

This patch will add and use internal APIs (rb_convert_type_with_id, rb_check_convert_type_with_id)
to call the method without looking up the method's id when convert the object.

watson1978 6e0e067de3 Improve performance of rb_equal()
* object.c (rb_equal): add optimized path to compare the objects using
    rb_equal_opt(). Previously, if not same objects were given, rb_equal() would
    call `==' method via rb_funcall() which took a long time.

    rb_equal_opt() has provided faster comparing for Fixnum/Float/String objects.
    Now, Time#eql? uses rb_equal() to compare with argument object and it will
    be faster around 40% on 64-bit environment.

* array.c (rb_ary_index): remove redundant rb_equal_opt() calling.
    Now, rb_equal() was optimized using rb_equal_opt().
    If rb_equal_opt() returns Qundef, it will invoke rb_equal() -> rb_equal_opt(),
    and it will cause the performance regression.

    So, this patch will remove first redundant rb_equal_opt() calling.

watson1978 044257c046 Improve performance in where push the element into non shared Array object
* array.c (ary_ensure_room_for_push): use rb_ary_modify_check() instead of
    rb_ary_modify() to check whether the object can be modified for non shared
    Array object. rb_ary_modify() has the codes for shared Array object too.
    In here, it has condition branch for shared / non shared Array object and
    it can use rb_ary_modify_check() which is smaller function than
    rb_ary_modify() for non shared object.

    rb_ary_modify_check() will be expand as inline function.
    If it will compile with GCC, Array#<< will be faster around 8%.

normal eeb36c5c74 mention behavior of Array#join for nested arrays [ci skip]
The current documentation for Array#join does not mention the
special treatment of nested arrays.

It says:
> Returns a string created by converting each element of the
> array to a string, separated by the given separator.

Expected behavior according to the docs would be:

    [ "a", [1, 2, [:x, :y]], "b" ].join("-")  #=> "a-[1, 2, [:x, :y]]-b"
    # because of:
    [1, 2, [:x, :y]].to_s  #=> "[1, 2, [:x, :y]]"

Actual behavior:

    [ "a", [1, 2, [:x, :y]], "b" ].join("-")  #=> "a-1-2-x-y-b"

because join is applied recursively for nested arrays.

The patch clarifies this behavior.

(Also: small markup and grammar fix.)

nobu 491c44e984 Clarify set intersection and union documentation
* array.c (rb_ary_and): clarify that set intersection returns the
  unique elements common to both arrays.

* array.c (rb_ary_or): clarify that union preserves the order from
  the given arrays.

- Most know what intersection means, but saying the operation
  excludes duplicates could be misleading ([1] & [1], duplicates
  excluded, might mean a result of []).
- Instead, saying intersection returns the unique elements common to both
  arrays is more concise and less ambiguous.
- The set union's documentation was incomplete in its describing
  preservation of order. Saying union preserves the order of the
  original array neglects the idea that the order of the elements
  in both arrays, as given, will be preserved.
- Instead, saying set union preserves the order from the given arrays (and
  adding an example) fully demonstrates the idea.
