卜部昌平 5e22f873ed decouple internal.h headers
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).

definition so far.

KOSAKI Motohiro 4d7a6d04b2 Avoid unnecessary tzset() call
Akatsuki reported ENV['TZ'] = 'UTC' improved 7x-8x faster on following code.
t = Time.now; 100000.times { Time.new(2019) }; Time.now - t
https://hackerslab.aktsk.jp/2019/12/01/141551

commit 4bc1669127(reduce tzset) dramatically improved this situation. But still,
TZ=UTC is faster than default.

This patch removs unnecessary tzset() call completely.

Performance check
  ----------------------
test program: t = Time.now; 100000.times { Time.new(2019) }; Time.now - t
before:         0.387sec
before(w/ TZ):  0.197sec
after:          0.162sec
after(w/ TZ):   0.165sec

OK. Now, Time creation 2x faster *and* TZ=UTC doesn't improve anything.
We can forget this hack completely. :)

Side note:
This patch slightly changes Time.new(t) behavior implicitly. Before this patch, it might changes
default timezone implicitly. But after this patch, it doesn't. You need to reset TZ
(I mean ENV['TZ'] = nil) explicitly.
But I don't think this is big impact. Don't try to change /etc/localtime on runtime.

Side note2: following test might be useful for testing "ENV['TZ'] = nil".
  -----------------------------------------
% cat <<'End' | sudo sh -s
rm -f /etc/localtime-; cp -a /etc/localtime /etc/localtime-
rm /etc/localtime; ln -s /usr/share/zoneinfo/Asia/Tokyo /etc/localtime
./ruby -e '
p Time.new(2000).zone # JST
File.unlink("/etc/localtime"); File.symlink("/usr/share/zoneinfo/America/Los_Angeles", "/etc/localtime")
p Time.new(2000).zone # JST (ruby does not follow /etc/localtime modification automatically)
ENV["TZ"] = nil
p Time.new(2000).zone # PST (ruby detect /etc/localtime modification)
'
rm /etc/localtime; cp -a /etc/localtime- /etc/localtime; rm /etc/localtime-

Jeremy Evans c5c05460ac Warn on access/modify of $SAFE, and remove effects of modifying $SAFE
This removes the security features added by $SAFE = 1, and warns for access
or modification of $SAFE from Ruby-level, as well as warning when calling
all public C functions related to $SAFE.

This modifies some internal functions that took a safe level argument
to no longer take the argument.

rb_require_safe now warns, rb_require_string has been added as a
version that takes a VALUE and does not warn.

One public C function that still takes a safe level argument and that
this doesn't warn for is rb_eval_cmd.  We may want to consider
adding an alternative method that does not take a safe level argument,
and warn for rb_eval_cmd.

卜部昌平 c9ffe751d1 delete unused functions
Looking at the list of symbols inside of libruby-static.a, I found
hundreds of functions that are defined, but used from nowhere.

specific to some platform, some are useful when debugging, etc).
However it seems the functions deleted here exist for no reason.

Use a monotonically increasing number for object_id
This changes object_id from being based on the objects location in
memory (or a nearby memory location in the case of a conflict) to be
based on an always increasing number.

This number is a Ruby Integer which allows it to overflow the size of a
pointer without issue (very unlikely to happen in real programs
especially on 64-bit, but a nice guarantee).

This changes obj_to_id_tbl and id_to_obj_tbl to both be maps of Ruby
objects to Ruby objects (previously they were Ruby object to C integer)
which simplifies updating them after compaction as we can run them
through gc_update_table_refs.

Dylan Thacker-Smith b970259044 Stop making a redundant hash copy in Hash#dup (#2489)
* Stop making a redundant hash copy in Hash#dup

It was making a copy of the hash without rehashing, then created an
extra copy of the hash to do the rehashing.  Since rehashing creates
a new copy already, this change just uses that rehashing to make
the copy.

[Bug #16121]

* Remove redundant Check_Type after to_hash

* Fix freeing and clearing destination hash in Hash#initialize_copy

The code was assuming the state of the destination hash based on the
source hash for clearing any existing table on it. If these don't match,
then that can cause the old table to be leaked. This can be seen by
compiling hash.c with `#define HASH_DEBUG 1` and running the following
script, which will crash from a debug assertion.

```ruby
h = 9.times.map { |i| [i, i] }.to_h
h.send(:initialize_copy, {})
```

* Remove dead code paths in rb_hash_initialize_copy

Given that `RHASH_ST_TABLE_P(h)` is defined as `(!RHASH_AR_TABLE_P(h))`
it shouldn't be possible for a hash to be neither of these, so there
is no need for the removed `else if` blocks.

* Share implementation between Hash#replace and Hash#initialize_copy

This also fixes key rehashing for small hashes backed by an array
table for Hash#replace.  This used to be done consistently in ruby
2.5.x, but stopped being done for small arrays in ruby 2.6.x.

This also bring optimization improvements that were done for
Hash#initialize_copy to Hash#replace.

* Add the Hash#dup benchmark

Jeremy Evans 660c7e050f Fix more keyword separation issues
This fixes instance_exec and similar methods. It also fixes
Enumerator::Yielder#yield, rb_yield_block, and a couple of cases
with Proc#{<<,>>}.

This support requires the addition of rb_yield_values_kw, similar to
rb_yield_values2, for passing the keyword flag.

Unlike earlier attempts at this, this does not modify the rb_block_call_func
type or add a separate function type.  The functions of type
rb_block_call_func are called by Ruby with a separate VM frame, and we can
get the keyword flag information from the VM frame flags, so it doesn't need
to be passed as a function argument.

These changes require the following VM functions accept a keyword flag:

* vm_yield_with_cref
* vm_yield
* vm_yield_with_block

John Hawthorn 21994b7fd6 Avoid rehashing keys in transform_values

Koichi Sasada 72825c35b0 Use 1 byte hint for ar_table [Feature #15602]
On ar_table, Do not keep a full-length hash value (FLHV, 8 bytes)
but keep a 1 byte hint from a FLHV (lowest byte of FLHV).
An ar_table only contains at least 8 entries, so hints consumes
8 bytes at most. We can store hints in RHash::ar_hint.

On 32bit CPU, we use 4 entries ar_table.

The advantages:
* We don't need to keep FLHV so ar_table only consumes
  16 bytes (VALUEs of key and value) * 8 entries = 128 bytes.
* We don't need to scan ar_table, but only need to check hints
  in many cases. Especially we don't need to access ar_table
  if there is no match entries (in many cases).
  It will increase memory cache locality.

The disadvantages:
* This technique can increase `#eql?` time because hints can
  conflicts (in theory, it conflicts once in 256 times).
  It can introduce incompatibility if there is a object x where
  x.eql? returns true even if hash values are different.
  I believe we don't need to care such irregular case.
* We need to re-calculate FLHV if we need to switch from ar_table
  to st_table (e.g. exceeds 8 entries).
  It also can introduce incompatibility, on mutating key objects.
  I believe we don't need to care such irregular case too.

Add new debug counters to measure the performance:
* artable_hint_hit - hint is matched and eql?#=>true
* artable_hint_miss - hint is not matched but eql?#=>false
* artable_hint_notfound - lookup counts

Koichi Sasada ebd398ac5a remove RHash::iter_lev.
iter_lev is used to detect the hash is iterating or not.
Usually, iter_lev should be very small number (1 or 2) so
`int` is overkill.

This patch introduce iter_lev in flags (7 bits, FL13 to FL19)
and if iter_lev exceeds this range, save it in hidden attribute.
We can get 1 word in RHash.

We can't modify frozen objects. Therefore I added new internal API
`rb_ivar_set_internal()` which allows us to set an attribute
even if the target object is frozen
if the name is hidden ivar (the name without `@` prefix).

shyouhei f98004c0f2 hash.c: cast from double to unsigned is undefined
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`.

shyouhei 3483e6dad4 hash.c: +(-1) is a wrong idea
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.

tenderlove efee3033b5 Include Hash#size in the examples
Both methods Hash#length and Hash#size share the same source code in
Ruby, but they also share the same documentation. Now when you look at
the documentation of Hash#size you only see examples for Hash#length,
which is confusing. This commit includes Hash#size in the examples and
also remarks that both methods are equivalent to each other.

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.
object.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.

NOTE: Rails performance was somehow a little degraded with JIT for now.
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 8880af9a3b Use UINT128_T support flag from configure
Current check for __uint128_t in hash.c is not valid, since it ignores
compilers other than gcc. We hit this on lcc on e2k platform.

Configure script properly checks from 128-bit data types support and
sets HAVE_UINT128_T accordingly. This approach is already used within
ruby at bignum.c, random.c, etc.

Probably hash.c is an overlooked remnant of old days. This patch fixes
this.

mame 0a6816ecd7 Revamp method coverage to support define_method
Traditionally, method coverage measurement was implemented by inserting
`trace2` instruction to the head of method iseq.  So, it just measured
methods defined by `def` keyword.

This commit drastically changes the measuring mechanism of method
coverage; at `RUBY_EVENT_CALL`, it keeps a hash from rb_method_entry_t*
to runs (i.e., it counts the runs per method entry), and at
`Coverage.result`, it creates the result hash by enumerating all
`rb_method_entry_t*` objects (by `ObjectSpace.each_object`).

shyouhei 0eb7359cc7 add rb_hash_new_with_size()
Sometimes, size of a hash can be calcluated a priori.  By providing
such info to the constructor we can avoid unnecessary internal re-
allocations.  This can boost for instance creation of hash literals.

normal d04c085b3c hash: keep fstrings of tainted strings for string keys
The same hash keys may be loaded from tainted data sources
frequently (e.g. parsing headers from socket or loading
YAML data from a file).  If a non-tainted fstring already
exists (because the application expects the hash key),
cache and deduplicate the tainted version in the new
tainted_frozen_strings table.

For non-embedded strings, this also allows sharing with the
underlying malloc-ed data.

normal e205304a3e Hash#[]= deduplicates string keys if (and only if) fstring exists
In typical applications, hash entries are read after being
written to.  Blindly writing to hashes which are never read
makes little sense. So, for any hash which is read from, an
fstring entry for the key should already exist for the key.

We no longer blindly create fstrings if the code is blindly
setting random hash keys, preventing the performance regression
in the reverted r43870.

Regarding <https://bugs.ruby-lang.org/issues/9188>, this has a
minimum impact on the bm_so_k_nucleotide where hash keys are set
and not reused, performance is within 1-2% of existing cases.

* hash.c: #include gc.h for rb_objspace_garbage_object_p
  (hash_aset_str): do read-only check of fstring table and
  reuse fstring if it exists and is still alive (not garbage)

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.

Same as rb_ary_tmp_new_from_values(), it reduces vm_exec_core binary
size from 26,176 bytes to 26,080 bytes.  But this time, also with a
bit of optimizations:

  - Because we are allocating a new hash and no back references are
    introduced at all, we can safely skip write barriers.

  - Also, the iteration never recurs.  We can avoid complicated
    function callbacks by using st_insert instead of st_update.

kazu 9fa8006a01 Cleanup ruby method definitions in hash.c
Always add a space between a comma and the next element. These spaces
were there sometimes, but not always. This keeps to code consistent.

normal e52b3a0e2c hash.c (rb_num_hash_start): avoid pathological behavior
The OR-ing itself is bad for a hash function, and shifting 3 bits
left was not enough to undo the damage done by shifting
(RUBY_SPECIAL_SHIFT+3) bits right.  Experimentally, shifting 16-17
bits seemed to work well in preparing the number for murmur hash.

Add a few more benchmarks to based on bm_hash_shift to ensure
we don't hurt performance too much with tweaks.

I'm pretty confident about this change and commiting it now;
especially since we're still using Murmur behind it (but perhaps
we can update to a newer hash from Murmur...)

normal 442b77e721 symbol.h: memoize hashval for RSymbol
This speeds up the hash function for dynamic symbols.
[ruby-core:70129] [Bug #11396], nearly up to Ruby 2.1 levels

Power-of-two hash sizing [Feature #9425] speeds up cases where we
have a good hash, but this means we can no longer hide behind weak
hashes.  Unfortunately, object IDs do not hash well, but we may
use the extra space in the RSymbol struct to memoize the hash value.

Further optimizations should be possible.  For now, the st.c APIs
force us to calculate rb_str_hash redundantly at dsym registration.

* symbol.h (struct RSymbol): add hashval field
* symbol.c (dsymbol_alloc): setup hashval field once
* hash.c (rb_any_hash): return RSymbol->hashval directly
* common.mk: hash.o depends on symbol.h

  [Feature #10440] (Details are described in this ticket)
  Most of complex part is moved to vm_args.c.
  Now, ISeq#to_a does not catch up new instruction format.
* vm_core.h: change iseq data structures.
  * introduce rb_call_info_kw_arg_t to represent keyword arguments.
  * add rb_call_info_t::kw_arg.
  * rename rb_iseq_t::arg_post_len to rb_iseq_t::arg_post_num.
  * rename rb_iseq_t::arg_keywords to arg_keyword_num.
  * rename rb_iseq_t::arg_keyword to rb_iseq_t::arg_keyword_bits.
    to represent keyword bitmap parameter index.
    This bitmap parameter shows that which keyword parameters are given
    or not given (0 for given).
    It is refered by `checkkeyword' instruction described bellow.
  * rename rb_iseq_t::arg_keyword_check to rb_iseq_t::arg_keyword_rest
    to represent keyword rest parameter index.
  * add rb_iseq_t::arg_keyword_default_values to represent default
    keyword values.
  * rename VM_CALL_ARGS_SKIP_SETUP to VM_CALL_ARGS_SIMPLE
    to represent
      (ci->flag & (SPLAT|BLOCKARG)) &&
      ci->blockiseq == NULL &&
      ci->kw_arg == NULL.
* vm_insnhelper.c, vm_args.c: rewrite with refactoring.
  * rewrite splat argument code.
  * rewrite keyword arguments/parameters code.
  * merge method and block parameter fitting code into one code base.
* vm.c, vm_eval.c: catch up these changes.
* compile.c (new_callinfo): callinfo requires kw_arg parameter.
* compile.c (compile_array_): check the last argument Hash object or
  not. If Hash object and all keys are Symbol literals, they are
  compiled to keyword arguments.
* insns.def (checkkeyword): add new instruction.
  This instruction check the availability of corresponding keyword.
  For example, a method "def foo k1: 'v1'; end" is cimpiled to the
  following instructions.
    0000 checkkeyword     2, 0  # check k1 is given.
    0003 branchif         9     # if given, jump to address #9
    0005 putstring        "v1"
    0007 setlocal_OP__WC__0 3   # k1 = 'v1'
    0009 trace            8
    0011 putnil
    0012 trace            16
    0014 leave
* insns.def (opt_send_simple): removed and add new instruction
  "opt_send_without_block".
* parse.y (new_args_tail_gen): reorder variables.
  Before this patch, a method "def foo(k1: 1, kr1:, k2: 2, **krest, &b)"
  has parameter variables "k1, kr1, k2, &b, internal_id, krest",
  but this patch reorders to "kr1, k1, k2, internal_id, krest, &b".
  (locate a block variable at last)
* parse.y (vtable_pop): added.
  This function remove latest `n' variables from vtable.
* iseq.c: catch up iseq data changes.
* proc.c: ditto.
* class.c (keyword_error): export as rb_keyword_error().
* common.mk: depend vm_args.c for vm.o.

ko1 123eeb1c1a * gc.c: add incremental GC algorithm. [Feature #10137]
Please refer this ticket for details.
  This change also introduces the following changes.
  * Remove RGENGC_AGE2_PROMOTION and introduce object age (0 to 3).
    Age can be count with FL_PROMOTE0 and FL_PROMOTE1 flags in
    RBasic::flags (2 bit). Age == 3 objects become old objects.
  * WB_PROTECTED flag in RBasic to WB_UNPROTECTED bitmap.
  * LONG_LIVED bitmap to represent living objects while minor GCs
    It specifies (1) Old objects and (2) remembered shady objects.
  * Introduce rb_objspace_t::marked_objects which counts marked
    objects in current marking phase. marking count is needed to
    introduce incremental marking.
  * rename mark related function and sweep related function to
    gc_(marks|sweep)_(start|finish|step|rest|continue).
  * rename rgengc_report() to gc_report().
  * Add obj_info() function to get cstr of object details.
  * Add MEASURE_LINE() macro to measure execution time of specific line.
  * and many small fixes.
* include/ruby/ruby.h: add flag USE_RINCGC.
  Now USE_RINCGC can be set only with USE_RGENGC.
* include/ruby/ruby.h: introduce FL_PROMOTED0 and add FL_PROMOTED1
  to count object age.
* include/ruby/ruby.h: rewrite write barriers for incremental marking.
* debug.c: catch up flag name changes.
* internal.h: add rb_gc_writebarrier_remember() instead of
  rb_gc_writebarrier_remember_promoted().
* array.c (ary_memcpy0): use rb_gc_writebarrier_remember().
* array.c (rb_ary_modify): ditto.
* hash.c (rb_hash_keys): ditto.
* hash.c (rb_hash_values): ditto.
* object.c (init_copy): use rb_copy_wb_protected_attribute() because
  FL_WB_PROTECTED is moved from RBasic::flags.
* test/objspace/test_objspace.rb: catch up ObjectSpace.dump() changes.
