[ruby/resolv] Fix confusion of received response message

This is a follow up for commit 33fb966197f1 ("Remove sender/message_id
	pair after response received in resolv", 2020-09-11).

As the @senders instance variable is also used for tracking transaction
	ID allocation, simply removing an entry without releasing the ID would
	eventually deplete the ID space and cause
	Resolv::DNS.allocate_request_id to hang.

It seems the intention of the code was to check that the received DNS
	message is actually the response for the question made within the method
	earlier. Let's have it actually do so.

Fix singleton class cloning

Before this commit, `clone` gave different results depending on whether the original object
	had an attached singleton class or not.

Consider the following setup:
	```
	class Foo; end
	Foo.singleton_class.define_method(:foo) {}

obj = Foo.new

obj.singleton_class if $call_singleton

clone = obj.clone
	```

When `$call_singleton = false`, neither `obj.singleton_class.singleton_class` nor
	`clone.singleton_class.singleton_class` own any methods.

However, when `$call_singleton = true`, `clone.singleton_class.singleton_class` would own a copy of
	`foo` from `Foo.singleton_class`, even though `obj.singleton_class.singleton_class` does not.

The latter case is unexpected and results in a visibly different clone, depending on if the original object
	had an attached class or not.

Don't double fractional seconds when passing timezone object to Time.new

I found that fractional seconds were doubled when using the timezone
	feature of Time in Sequel's named_timezones extension (which uses
	TZInfo for the timezone object), and traced the problem to this code.

There is no subsecx being modified in the utc_to_local call below
	this, and I'm not sure why you would want to add in the fractional
	seconds unless you assumed the timezone conversion would drop the
	existing fractional seconds (TZInfo doesn't drop fractional seconds).

Subsecond of Time::tm should be 0

Fix Method#super_method for aliased methods

Previously, Method#super_method looked at the called_id to
	determine the method id to use, but that isn't correct for
	aliased methods, because the super target depends on the
	original method id, not the called_id.

Additionally, aliases can reference methods defined in other
	classes and modules, and super lookup needs to start in the
	super of the defined class in such cases.

This adds tests for Method#super_method for both types of
	aliases, one that uses VM_METHOD_TYPE_ALIAS and another that
	does not. Both check that the results for calling super
	methods return the expected values.

To find the defined class for alias methods, add an rb_ prefix
	to find_defined_class_by_owner in vm_insnhelper.c and make it
	non-static, so that it can be called from method_super_method
	in proc.c.

This bug was original discovered while researching [Bug #11189].

Don't require sub-word atomics

On some architectures (like RISC-V) sub-word atomics are only available
	when linking against -latomic, but the configure script doesn't do that,
	causing the atomic checks to fail and the resulting ruby binary is
	non-functional.  Ruby does not use sub-word atomic operations, rb_atomic_t
	is defined to unsigned int, so use unsigned int when checking for atomic
	operations.

Allow Dir.home to work for non-login procs when $HOME not set

Allow the 'Dir.home' method to reliably locate the user's home directory when
	all three of the following are true at the same time:

1. Ruby is running on a Unix-like OS
	2. The $HOME environment variable is not set
	3. The process is not a descendant of login(1) (or a work-alike)

The prior behavior was that the lookup could only work for login-descended
	processes.

This is accomplished by looking up the user's record in the password database
	by uid (getpwuid_r(3)) as a fallback to the lookup by name (getpwname_r(3))
	which is still attempted first (based on the name, if any, returned by
	getlogin_r(3)).

If getlogin_r(3), getpwnam_r(3), and/or getpwuid_r(3) is not available at
	compile time, will fallback on using their respective non-*_r() variants:
	getlogin(3), getpwnam(3), and/or getpwuid(3).

The rationale for attempting to do the lookup by name prior to doing it by uid
	is to accommodate the possibility of multiple login names (each with its own
	record in the password database, so each with a potentially different home
	directory) being mapped to the same uid (as is explicitly allowed for by
	POSIX; see getlogin(3posix)).

Preserves the existing behavior for login-descended processes, and adds the
	new capability of having Dir.home being able to find the user's home directory
	for non-login-descended processes.

Remove sender/message_id pair after response received in resolv

Once a response for a given DNS request has been received (which
	requires a matching message id), the [sender, message_id] pair
	should be removed from the list of valid senders.  This makes it
	so duplicate responses from the same sender are ignored.

configure.ac: Bump the size of sigaltstack

The RubyVM uses C macro defines to feature detect whether
	`backtrace(2)` support is available, and if so it includes C level backtraces
	when the RubyVM itself crashes.

But on my machine, C level backtraces from `vm_dump.c` didn't work when
	using a version of Ruby buillt on the machine, but worked fine when using a
	version of Ruby built on another machine and copied to my machine.

The default autoconf test for backtraces uses a sigaltstack size that is
	too small, so the SIGSEGV signal handler itself causes a SIGSEGV).
	I noticed that signal.c uses a larger sigaltstack size:

https://github.com/ruby/ruby/blob/v2_6_5/signal.c#L568

The specific variables it looks at:

- `HAVE_BACKTRACE`

this is a macro defined by autoconf because there is a line in the
	  configure script like `AC_CHECK_FUNCS(backtrace)` (see the autoconf
	  docs for more).

- `BROKEN_BACKTRACE`

this comes from a custom program that Ruby's configure script runs to
	  attempt to figure out whether actually using backtrace(2) in a real
	  program works. You can see the autoconf program here.

<https://github.com/ruby/ruby/blob/v2_6_5/configure.ac#L2817-L2863>

It uses sigaltstack and SA_ONSTACK to create a seperate stack for
	handling signals.

The problem was: SIGSTKSZ (which comes from a system header!) was not
	suggesting a large enough stack size. When checking on an Ubuntu 16.04
	box, we found that SIGSTKSZ was 8192 and MINSIGSTKSZ was 2048.

compile.c: stop wrong peephole optimization when covearge is enabled

jump-jump optimization ignores the event flags of the jump instruction
	being skipped, which leads to overlook of line events.

This changeset stops the wrong optimization when coverage measurement is
	neabled and when the jump instruction has any event flag.

Note that this issue is not only for coverage but also for TracePoint,
	and this change does not fix TracePoint.
	However, fixing it fundamentally is tough (which requires revamp of
	the compiler).  This issue is critical in terms of coverage measurement,
	but minor for TracePoint (ko1 said), so we here choose a stopgap
	measurement.

[Bug #15980] [Bug #16397]

Note for backporters: this changeset can be viewed by `git diff -w`.

Prefer using MJIT_CC for JIT support check

because Solaris might have CC=cc and we'd like to check full path
	MJIT_CC=/opt/developerstudio12.5/bin/cc instead.

MJIT_CC is always an absolute path.

time.c (find_time_t): fix round-to-zero bug

`find_time_t` did not work correctly for year older than the Epoch
	because it used C's integer division (which rounds negative to zero).

For example, `TIme.new(1933)` returned a wrong time whose year is 1922
	in Asia/Kuala_Lumpur because there is no 00:00:00 1st Jan. 1933 in the
	time zone.

```
	$ TZ=Asia/Kuala_Lumpur ruby -e 'p Time.new(1933)'
	1932-12-31 00:00:00 +0700
	```

This change fixes the issue by using `DIV` macro instead of `/`.
	Now `Time.new(1933)` returns a time in 1933.

```
	$ TZ=Asia/Kuala_Lumpur ruby -e 'p Time.new(1933)'

Tag string shared roots to fix use-after-free

The buffer deduplication codepath in rb_fstring can be used to free the buffer
	of shared string roots, which leads to use-after-free.

Introudce a new flag to tag strings that at one point have been a shared root.
	Check for it in rb_fstring to avoid freeing buffers that are shared by
	multiple strings. This change is based on nobu's idea in [ruby-core:94838].

The included test case test for the sequence of calls to internal functions
	that lead to this bug. See attached ticket for Ruby level repros.

Fix a use-after-free bug by avoiding rb_str_new_frozen

`str2 = rb_str_new_frozen(str1)` seems to make str1 a shared string that
	refers to str2, but str2 is not marked as STR_IS_SHARED_M nor
	STR_NOFREE.
	`rb_fstring(str2)` frees str2's ptr because it is not marked, and the
	free'ed pointer is the same as str1's ptr.
	After that, accessing str1 may cause use-after-free memory corruption.

I guess this is a bug of rb_str_new_frozen, but I'm completely unsure
	what it should be; the string states and flags are not documented.
	So, this is a workaround for [Bug #16136].  I confirmed that rspec of
	activeadmin runs gracefully.

The following script triggers use-after-free on trunk, 2.4.6, 2.5.5
	and 2.6.3. Credits to @wanabe for using eval as a cross-version way
	of registering a fstring.

```ruby

	4.times { GC.start }
	p a

str_duplicate: Don't share with a frozen shared string

This is a follow up for 3f9562015e651735bfc2fdd14e8f6963b673e22a.
	Before this commit, it was possible to create a shared string which
	shares with another shared string by passing a frozen shared string
	to `str_duplicate`.

Such string looks like:

```
	 --------                    -----------------
	 | root | ------ owns -----> | root's buffer |
	 --------                    -----------------
	     ^                             ^   ^
	 -----------                       |   |
	 | shared1 | ------ references -----   |
	 -----------                           |
	     ^                                 |
	 -----------                           |
	 | shared2 | ------ references ---------
	 -----------
	```

This is bad news because `rb_fstring(shared2)` can make `shared1`
	independent, which severs the reference from `shared1` to `root`:

```c
	/* from fstr_update_callback() */
	str = str_new_frozen(rb_cString, shared2);  /* can return shared1 */
	if (STR_SHARED_P(str)) { /* shared1 is also a shared string */
	    str_make_independent(str);  /* no frozen check */
	}
	```

If `shared1` was the only reference to `root`, then `root` can be
	reclaimed by the GC, leaving `shared2` in a corrupted state:

```
	 -----------                         --------------------
	 | shared1 | -------- owns --------> | shared1's buffer |
	 -----------                         --------------------
	      ^
	      |
	 -----------                         -------------------------
	 | shared2 | ------ references ----> | root's buffer (freed) |
	 -----------                         -------------------------
	```

Here is a reproduction script for the situation this commit fixes.

```ruby
	a = ('a' * 24).strip.freeze.strip
	-a
	p a
	4.times { GC.start }
	p a
	```

- string.c (str_duplicate): always share with the root string when
	   the original is a shared string.
	 - test_rb_str_dup.rb: specifically test `rb_str_dup` to make
	   sure it does not try to share with a shared string.

Fix process not waking up on signals on OpenBSD

When using UBF_TIMER_PTHREAD (the UBF handler on OpenBSD), the
	timer_pthread_fn function will not signal the main thread with
	SIGVTALRM in cases where timer_pthread is armed before
	consume_communication_pipe is called.  This is because
	consume_communication_pipe will unarm the timer.

Fix this by checking the return value of consume_communication_pipe.
	If it returns TRUE and the timer_pthread is disarmed, then signal
	the main thread with SIGVTALRM.

On OpenBSD, this fixes TestThread#test_thread_timer_and_interrupt, and
	fixes hangs in TestProcess#test_execopts_redirect_open_fifo_interrupt_raise
	and TestProcess#test_execopts_redirect_open_fifo_interrupt_print.
	It also fixes the use of Ctrl+C/SIGINT in irb on OpenBSD. It does not
	cause any test failures on Linux when UBF_TIMER_PTHREAD is forced as
	the UBF handler.

Fix mixed encoding in heredoc

Heredocs are parsed line-by-line, so we need to keep track of the
	temporary encoding of the string.  Previously, a heredoc would
	only detect mixed encoding errors if they were on the same line,
	this changes things so they will be caught on different lines.

add logic to handle Unicode beta period file names

In downloader.rb, add logic to handle file names of the form
	UnicodeData-12.0.0d6.txt. To find the right file, we download
	the index of the directory. Then we download the files by finding
	the file names from the index. Files are always checked for changes,
	because changes might be frequent during the beta period.
	We also check whether any index.html files are left when we are not
	in the beta period. This would indicate that we might have stale
	data from the beta period rather than the actual release data.

simplify filename-related code

(Thanks to Nobuyoshi Nakada for the hint!)

downloader.rb: keep linked file newer than cached file

* tool/downloader.rb (Downloader.save_cache): keep linked file
	  newer than cached file, so that GNU make triggers when the
	  content is updated.  it uses the timestamp of symlink itself
	  instead of the target.

add puts statements to debug Unicode file download (temporary)

Unicode file download doesn't work with Visual Studio, see e.g.
	https://ci.appveyor.com/project/ruby/ruby/builds/23614399/job/f8vya2l7fjdfcye4
	We temporarily produce more output for debugging.

* remove trailing spaces.

output more debug information in downloader.rb (temporary)

Unicode file download doesn't work with Visual Studio, we need more debug output.

downloader.rb: quote base name

downloader.rb: fix typo, extra %

revert r67445, (r67446,) r67447

Debugging output is no longer needed because the problem has been fixed with r67449.

Bump version to date-2.0.0.

I forgot to change it when Ruby 2.6.0 was released.

date_parse.c: extract Japanese era initials

* expand tabs.

date_parse.c: removed 'r' which is not in JIS X 0301 yet

Added tests for end of Heisei

date: use del_hash to extract an element destructively

* expand tabs.

date_parse.c: renamed JAPANESE prefix as JISX0301

date_parse.c: name JISX0301_DEFAULT_ERA

date: make zone a substring to copy encoding and taintedness

* expand tabs.

date_core.c: [DOC] Heisei will be assumed if no-era [ci skip]

date: support for Reiwa, new Japanese era

change lib/unicode_normalize/tables.rb to single item per line to make diffs shorter

* template/unicode_norm_gen.tmpl: Change formatting of output to produce only a
          single item (or range) for each line to make future diffs shorter and easier
          to understand and check.

* lib/unicode_normalize/tables.rb: output of the above

update to Unicode Version 12.1.0 (beta)

Unicode Version 12.1.0 adds one single character, U+32FF SQUARE ERA NAME REIWA,
        for the new Japanese era starting on May 1st. 12.1.0 will be finalized only on
        May 7th, so we go with the beta version because further changes in the data we
        need are highly unlikely, and we want to make sure Ruby is ready for the new era.

* common.mk: change UNICODE_VERSION to 12.1.0, UNICODE_BETA to YES

* enc/unicode/12.1.0, enc/unicode/12.1.0/casefold.h, enc/unicode/12.1.0/name2ctype.h:
          add directory and generated data files for new version

* lib/unicode_normalize/tables.rb: update for new character

* test/ruby/test_regexp.rb: add test for character property age=12.1

* test/test_unicode_normalize.rb: add test for NFKC decomposition of new character

This (mostly) completes issue #15195.

These changes break the behavior of default gems. Bug #13428 says

	  method. But I revert `to_ruby_for_cache` in rbinstall.rb at r58403.
	  There is no reason that we apply r58345 now.

st.c (rb_hash_bulk_insert_into_st_table): avoid out-of-bounds write

"hash_bulk_insert" first expands the table, but the target size was
	wrong: it was calculated by "num_entries + (size to buld insert)", but
	it was wrong when "num_entries < entries_bound", i.e., it has a deleted
	entry.  "hash_bulk_insert" adds the given entries from entries_bound,
	which led to out-of-bounds write access.  [Bug #15536]

As a simple fix, this commit changes the calculation to "entries_bound +
	size".  I'm afraid if this might be inefficient, but I think it is safe
	anyway.

mjit_worker.c: untangle CC_LIBS nesting

This should have no impact.
	The CC_LIBS was too hard to read for human.

I don't remember whether the order of -lmsvcrt and -lgcc matters or not,
	but I kept that for the best safety.

mjit_worker.c: pass -lgcc to GCC platforms

using `-nodefaultlibs -nostdlib`.

I assume libgcc is needed when we use -nostdlib, and it's linked on some
	platforms but not linked on some platforms (like aarch64, and possibly
	AIX as well) as said in https://wiki.osdev.org/Libgcc :

> You can link with libgcc by passing -lgcc when linking your kernel
	with your compiler. You don't need to do this unless you pass the
	-nodefaultlibs option (implied by -nostdlib)

Also note that -nostdlib is not strictly needed (rather implied
	-nodefaultlibs is problematic for Gentoo like Bug#15513, which will be
	approached later) but helpful for performance. So I want to keep it for
	now.

[Bug #15522]

I'm not trying to add `-nodefaultlibs -nostdlib` for AIX in this commit
	because AIX RubyCI is dead right now, but I'll try to add them again
	once RubyCI is fixed.

mjit_worker.c: try passing -nostdlib to AIX

r66812 might have allowed this. Testing.

remove "deprecated" for rb_frame_method_id_and_class [Bug #15300]

* include/ruby/backward.h (rb_frame_method_id_and_class): we had labeled
  `rb_frame_method_id_and_class()` as deprecated because MRI internal
  doesn't use it, but we found there are user of this API in external
  C-extensions. Now we don't have proper alternative API and no time
  to make alternative API, so I remove "deprecated" label.

thread_sync.c (rb_mutex_t): eliminate fork_gen

The true bug fork_gen was hiding was rb_mutex_abandon_locking_mutex
failing to unconditionally clear the waitq of mutexes it was
waiting on.  So we fix rb_mutex_abandon_locking_mutex, instead,
and eliminate rb_mutex_cleanup_keeping_mutexes.

was my most reliable reproducer of the "crash.rb" script from
[Bug #15383]

.travis.yml: avoid using -j3 for osx

osx build has failed too often. we don't know why.

To know which test hangs forever, we might want to have hard timeout for
all test case (like 9min, slightly less than no-output timeout) in test-all.
But it's a little hard to implement and I would workaround an unknown
cause somehow.

It's known that -j is harmful for some tests in test-all. Let's try to
remove it first, and if it doesn't work, I'll resurrect -v option to
easily know which test is the culprit.

Slow correctness is much better than fast false-positive.

Freeze hash literals embedded in duphash instructions

Previously, these hash literals were not frozen, and thus could be
modified by ObjectSpace, resulting in undesired behavior.  Example:

```ruby
require 'objspace'

def a(b={0=>1,1=>4,2=>17})
  b
end

p a
ObjectSpace.each_object(Hash) do |a|
  a[3] = 8 if a.class == Hash && a[0] == 1 && a[1] == 4 && a[2] == 17
end
p a
```

It may be desirable to hide such hashes from ObjectSpace, since
they are internal, but I'm not sure how to do that.

webrick: add the ability to override res, req creation

So that a customized HTTPServer subclass can use it's own
Request/Response classes.

To apply the override, make a subclass of WEBrick::HTTPServer
and override the
`create_request_and_response(with_webrick_config)` method. The
method should return an Array of [request, response].

To check whether the Server supports this method (i.e. when
using older versions of WEBrick when needing this
functionality), you can ask the server if it responds to the
method

server.respond_to?(:create_request_and_response)

This is backportable.

avoid passing unnecessary options to download method

add option to deal with Unicode beta data files

Unicode uses file names with explicit versions for beta publication.
This commit introduces a variable on the makefile level to distinguish
between beta and regular versions of file names.
 
common.mk: Define new variable UNICODE_BETA, usually set to NO,
but would be YES during tests with beta data files. Pass the value
of this variable to tool/downloader.rb with option --unicode-beta.

tool/downloader.rb: Receive and store value of --unicode-beta.
Raise an exception if value is YES, because we don't yet actually
deal with this case. Continue as usual if value is not YES.

This completes the changes needed in the makefile. Upcomming changes
will only affect tool/downloader.rb.

thread_pthread.c: fix memory leak from fork loop leapfrog (v3)

Constantly forking a single-threaded process in a loop leads to
a memory leak when using POSIX timers.  This fixes the leak for
GNU/Linux systems running glibc.

v2: disarm before timer_delete
v3: ubf_timer_arm prevents double-arming

This unreverts r66291 / commit ab73ef6b7037039a05edcbf2a0c1b1108197e036
Example Linux-only reproduction may be found in:

test/lib/test/unit.rb: do not propagate MAKEFLAGS to children

Propagating MAKEFLAGS to children running test/unit caused stuck
tests with GNU make when "-jN" is passed in both the make(1)
command-line and the "TESTS=" variable; because the forked child
process would see MAKEFLAGS and try to use jobserver on its own.

This is regression caused by r64399
(commit b53fadfd5f200dbd6fe9f4b2a91ebb68618e59bb,
"process.c: defaults to close_others false");
but that change also fixed a regression when close-on-exec

Uncontended GVL waitqueue could mean a single CPU setup where
threads are starved and can't even insert themselves into our

the GVL in an uncontended state, in the hope that we can
avoid entering the slow path of ppoll and similar syscalls.

This should prevent test/ruby/test_thread.rb::test_signal_at_join
timeout problems on our single CPU FreeBSD CI machine.

unassigned codepoints in the Georgian MTAVRULI range (U+1CBB, U+1CBC)
do not get converted to unrelated codepoints by String#capitalize.
(It turns out that this test was not strictly necessary, because
unassigned codepoints are already excluded by the fact that they are
not found in the onigenc_unicode_fold_lookup table. So this test only

Remove unnecessary require of fileutils

Today I updated my ruby core clone, and I run the usual steps to compile
ruby. When running "make", I run into the following error:

```
(... stuff ...)
encdb.h unchanged
Traceback (most recent call last):
	5: from ./tool/mkconfig.rb:19:in `<main>'
	4: from ./tool/mkconfig.rb:19:in `require'
	3: from /home/deivid/Code/ruby/lib/fileutils.rb:4:in `<top (required)>'
	2: from /home/deivid/Code/ruby/lib/fileutils.rb:4:in `require'

uncommon.mk:780: recipe for target '.rbconfig.time' failed
make: *** [.rbconfig.time] Error 1
```

Apparently, the script that generates the root `rbconfig.rb` file requires
`fileutils`, which in turn requires 'rbconfig' (for mjit-headers it says in a
comment), which uses the `rbconfig.rb` config file in the root folder if it
exists. In my case, this file existed but had been generated on 2.5.0, thus
causing the error.

I think we can avoid this sort of circular dependency by not requiring
`fileutils`, since it does not seem to be used anywhere in the
`tool/mkconfig.rb` script since r55338.

implement special behavior for Georgian for String#capitalize

The modern Georgian script is special in that it has an 'uppercase'
variant called MTAVRULI which can be used for emphasis of whole words,
for screamy headlines, and so on. However, in contrast to all other
bicameral scripts, there is no usage of capitalizing the first letter
in a word or a sentence. Words with mixed capitalization are not used
at all.

We therefore implement special behavior for String#capitalize. Formally,
we define String#capitalize as first applying String#downcase for the
whole string, then using titlecase on the first letter. Because Georgian
defines titlecase as the identity function both for MTAVRULI ('uppercase')
and Mkhedruli (lowercase), this results in String#capitalize being
equivalent to String#downcase for Georgian. This avoids undesirable
mixed case.

* enc/unicode.c: Actual implementation

* string.c: Add mention of this special case for documentation

* test/ruby/enc/test_case_mapping.rb: Add two tests, a general one
  that uses String#capitalize on some (including nonsensical)
  combinations of MTAVRULI and Mkhedruli, and a canary test to
  detect the potential assignment of characters to the currently
  open slots (holes) at U+1CBB and U+1CBC.

* test/ruby/enc/test_case_comprehensive.rb: Tweak generation of

zlib (gzfile_write_raw): do not resize string after .write call

Apparently, a component of Rails implements a buffering .write
method which keeps the String buffer around and makes it unsafe
for us to clear it after calling .write.

This caused Rack::Deflater to give empty results when enabled.

Fortunately, per r61631 / a55abcc0ca6f628fc05304f81e5a044d65ab4a68,
this misguided optimization was only worth a small (0.5MB) savings
and we still benefit from the majority of the memory savings in
that change.

Thanks to zunda for the bug report.

remove code duplication and put everything into forward order

In file regparse.c, in function node_extended_grapheme_cluster(),
eliminate code duplication of CRLF and '.' (any character). This
uses the fact that both for Unicode encodings and for non-Unicode
encodings, the first alternative is CRLF, and the last alternative
is '.' (any character). This puts all of the pieces into forward
order (the order of the code follows the order of the syntax
definition).

Speed up hash literals by duping

This commit replaces the `newhashfromarray` instruction with a `duphash`
instruction.  Instead of allocating a new hash from an array stored in
the Instruction Sequences, store a hash directly in the instruction
sequences and dup it on execution.

== Instruction sequence changes ==

```ruby
code = <<-eorby
  { "foo" => "bar", "baz" => "lol" }
eorby

insns = RubyVM::InstructionSequence.compile(code, __FILE__, nil, 0, frozen_string_literal: true)
puts insns.disasm
```

On Ruby 2.5:

```
== disasm: #<ISeq:<compiled>@test.rb:0 (0,0)-(0,36)>====================
0000 putobject        "foo"
0002 putobject        "bar"
0004 putobject        "baz"
0006 putobject        "lol"
0008 newhash          4
0010 leave
```

Ruby 2.6@r66174 3b6321083a2e3525da3b34d08a0b68bac094bd7f:

```
$ ./ruby test.rb
== disasm: #<ISeq:<compiled>@test.rb:0 (0,0)-(0,36)> (catch: FALSE)
0000 newhashfromarray             2, ["foo", "bar", "baz", "lol"]
0003 leave
```

Ruby 2.6 + This commit:

```
$ ./ruby test.rb
== disasm: #<ISeq:<compiled>@test.rb:0 (0,0)-(0,36)> (catch: FALSE)
0000 duphash                      {"foo"=>"bar", "baz"=>"lol"}
0002 leave
```

make sure all nodes are freed on error in node_extended_grapheme_cluster()

regparse.c: In function node_extended_grapheme_cluster(), use function-global
array node_common and use it for list and alternate construction. This is done
so that in case of error, all nodes that have already been constructed can be
correctly freed in a single for loop. Document the layout structure.

remove code duplication and streamline identifiers

In regparse.c:

* Reduce coode duplication by merging the almost identical functions
  create_sequence_node and create_alternate_node into a new function
  create_node_from_array, adding a parameter that distinguishes  between
  creating a list and creating an alternative.

* Streamline variable/function naming. Unicode UAX #29 uses 'sequence', but
  the regular expression library uses 'list' for the same concept. Keep
  'sequence' in the ccmments that are taken from UAX #29, but use 'list'
  in variable names.

Before this patch Array#all? was not implemented in Array class
and alternatively Enumerable#all? was used, while #any? has its
own method entry in Array class.  Similarly, Array#none? and #one?
also lacks its own implementation.
This patch provides Array-specific implementations for above three
methods to enable faster method lookup.

process.c: fix ETXTBUSY from MJIT compiler process

This affects test/ruby/test_process.rb (test_execopt_env_path).

Since MJIT uses vfork+execve in a separate thread, there can be
small window in-between vfork and execve where tmp_script.cmd is
held open by the vforked child.  vfork only pauses the MJIT
thread, not any Ruby Threads, so our call to Process.spawn will
hit ETXTBUSY in that window unless we fork.

main thread                       | MJIT thread
----------------------------------------------------
fd = open(tmp)                    |                |
                                  | vfork for CC   |   CC running

              | execve => TXTBUSY |                |
              |                   |                | execve (FD_CLOEXEC on fd)
              |                   | vfork returns  |

Holding the waitpid_lock whenever we intend to spawn a process
prevents the MJIT thread from spawning a process while we are
spawning in Ruby-land.

  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.

spec/ruby/core/io/*_spec.rb: explain MJIT failures

These random failures happen because FD number allocation
is not predictable when multiple threads are running (since
MJIT thread is opening/closing files all the time).

Real-world code practically never relies on predictable FD
number allocation (because much real-world code is
multi-threaded); so it's highly unlikely there'll be any
breakage to the user.

vm_trace.c: workqueue as thread-safe version of postponed_job

postponed_job is safe to use in signal handlers, but is not

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"

Remove HEAP_ALIGN_LOG setting in configure.ac for OpenBSD/MirOS

The ruby setting was renamed to HEAP_PAGE_ALIGN_LOG, but the
configure.in (now configure.ac) file was not updated, so the
setting had no effect.  The configure setting is unnecessary
after OpenBSD 5.2 and MirOS has been discontinued (with the last
release being over 10 years ago), so it is better to just remove
the related configure setting.

.travis.yml: cache unicode.org files

Before this changeset (since r58071) we did not download files
from unicode.org but just touch some files.  This is a kind of
hack that people normally don't do at home.

We are caching other files between builds now.  Why not also save
those files downloaded from elsewhere.  This covers more

io.c (rb_update_max_fd): use F_GETFL if possible

On 64-bit Linux, fstat() needs to fill out a 144 byte struct
while F_GETFL only needs to return 8 bytes.

check; so it's obviously more expensive than F_GETFL on Linux.

"struct stat" is 144 bytes on my 64-bit Linux.

but increases safety if called from deep machine stacks.

Support targetting TracePoint [Feature #15289]

* vm_trace.c (rb_tracepoint_enable_for_target): support targetting
  TracePoint. [Feature #15289]

Tragetting TracePoint is only enabled on specified method, proc
  and so on, example: `tp.enable(target: code)`.

`code` should be consisted of InstructionSeuqnece (iseq)
  (RubyVM::InstructionSeuqnece.of(code) should not return nil)
  If code is a tree of iseq, TracePoint is enabled on all of
  iseqs in a tree.

Enabled tragetting TracePoints can not enabled again with
  and without target.

* vm_core.h (rb_iseq_t): introduce `rb_iseq_t::local_hooks`
  to store local hooks.
  `rb_iseq_t::aux::trace_events` is renamed to
  `global_trace_events` to contrast with `local_hooks`.

* vm_core.h (rb_hook_list_t): add `rb_hook_list_t::running`
  to represent how many Threads/Fibers are used this list.
  If this field is 0, nobody using this hooks and we can
  delete it.

This is why we can remove code from cont.c.

* vm_core.h (rb_vm_t): because of above change, we can eliminate
  `rb_vm_t::trace_running` field.
  Also renamed from `rb_vm_t::event_hooks` to `global_hooks`.

* vm_core.h, vm.c (ruby_vm_event_enabled_global_flags): renamed
  from `ruby_vm_event_enabled_flags.

* vm_core.h, vm.c (ruby_vm_event_local_num): added to count
  enabled targetting TracePoints.

* vm_core.h, vm_trace.c (rb_exec_event_hooks): accepts
  hook list.

* vm_core.h (rb_vm_global_hooks): added for convinience.

* method.h (rb_method_bmethod_t): added to maintain Proc
  and `rb_hook_list_t` for bmethod (defined by define_method).

* prelude.rb (TracePoint#enable): extracet a keyword parameter
  (because it is easy than writing in C).
  It calls `TracePoint#__enable` internal method written in C.

* vm_insnhelper.c (vm_trace): check also iseq->local_hooks.

* vm.c (invoke_bmethod): check def->body.bmethod.hooks.

* vm.c (hook_before_rewind): check iseq->local_hooks
  and def->body.bmethod.hooks before rewind by exception.

lib/webrick: explicitly convert header values to a string

The values of @header are expected to be all strings;

non-String to @header.  This change fixes the issues.

The values are checked by `header_value =~ /\r\n/` in check_header.

add tests using Unicode test data for grapheme clusters

Add file test/ruby/enc/test_grapheme_breaks.rb to test String#each_grapheme_cluster
and \X extended grapheme cluster matcher in regular expressions against test data
provided by Unicode (ucd/auxiliary/GraphemeBreakTest.txt).

Some lines in the data file are ignored, as follows:
- Lines with a surrogate, because Ruby doesn't handle these
- The case of "\r\n", because there is a bug (#15337) in the implementation

thread.c (rb_wait_for_single_fd): do not miss IO#close notifications

RUBY_VM_CHECK_INTS_BLOCKING may switch threads and cause `fd'
to be closed.  So we must ensure we register the waiting_fd
before checking for interrupts.

This only affects the ppoll/poll-using implementation of
rb_wait_for_single_fd, as the select-based implementation
already register waiting_fd before checking for interrupts.

io.c (fptr_finalize_flush): close race leading to EBADF

The previous ordering was:

a) notify waiting_fd threads of impending close
b) waiting on busy list from a)
c) invalidate fptr->fd
d) calling close()

However, it was possible for a new thread to enter
the waiting_fd list while scheduling on b), leading
to EBADF from those threads when we hit d).

Instead, we now avoid triggering EBADF in other threads by
reordering b) and c)

a) notify waiting_fd threads of impending close
c) invalidate fptr->fd
b) waiting on busy list from a)
d) calling close()

io + socket: make pipes and sockets nonblocking by default

All normal Ruby IO methods (IO#read, IO#gets, IO#write, ...) are
all capable of appearing to be "blocking" when presented with a
file description with the O_NONBLOCK flag set; so there is
little risk of incompatibility within Ruby-using programs.

The biggest compatibility risk is when spawning external
programs.  As a result, stdin, stdout, and stderr are now always
made blocking before exec-family calls.

This change will make an event-oriented MJIT usable if it is
waiting on pipes on POSIX_like platforms.

It is ALSO necessary to take advantage of (proposed lightweight
concurrency (aka "auto-Fiber") or any similar proposal for
network concurrency: https://bugs.ruby-lang.org/issues/13618

Named-pipe (FIFO) are NOT yet non-blocking by default since
they are rarely-used and may introduce compatibility problems
and extra syscall overhead for a common path.

Please revert this commit if there are problems and if I am afk
since I am afk a lot, lately.

vm_insnhelper.c: recv -1 + 3 overflows

Here, recv can be INT2FIX(-1), which is 0xFFFF_FFFFul.
INT2FIX(1) is 3ul.  So `recv - 1 + INT2FIX(1)` is:

recv              0xFFFF_FFFFul
recv-1            0xFFFF_FFFEul (note: unsigned)
recv-1+INT2FIX(1) 0x0000_0001ul Here is the overflow.

Given recv is a Fixnum, it can never be 0xFFFF_FFFD.  0xFFFF_FFFF is
the only value that can overflow this way, so special-casing this
value should just suffice.

pack.c: cast from double to float can be undefined

Generally speaking, a value of double is not always representable
when demoted to a float. ISO C defines what to do when such
conversion loses precision, but leaves it undefined when the
value is completely out of range. (cf: ISO/IEC 9899:1990 section
6.2.1.4).

Because ruby do not have half-precision floating-point types this
is not a frequent headache but for pack / unpack, there are
specifiers that has something to do with C float types.  We have
to explicitly care these situations.

bignum.c: BDIGIT might or might not integer-promote

BDIGIT can be unsigned int or unsigned short, depending on BDIGIT_DBL.
Given that, unsigned int and unsigned short are different in how
integer promotion works.  BOGLO assumes its argument is wider than
BDIGIT, which is not always true.  We have to force that explicitly.

enc/unicode.c: 'a' is bigger than 'A'

In ASCII, 'a' is bigger than 'A'. Which means 'A' - 'a' is a negative
number (-32, to be precise). In C, the type of 'a' and 'A' are signed
int (cf: ISO/IEC 9899:1990 section 6.1.3.4). So 'A' - 'a' is also a
signed int. It is `(signed int)-32`.

The problem is, OnigCodePoint is unsigned int. Adding a negative
number to a variable of OnigCodepoint (`code` here) introduces an
unintentional cast of `(unsigned)(signed)-32`, which is
4,294,967,264. Adding this value to code then overflows, and the
result eventually becomes normal codepoint.

The series of operations are not a serious problem but because
`code >= 'a'` holds, we can `(code - 'a') + 'A'` to reroute this.

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`.

.travis.yml: enable ccache

Travis has `cache: ccache` feature so let us enable it.  Also, because
`config.cache` is generated during the compilation why not cache that
file for a later use.  [fix GH-2013]

Caveats:

- When something went wrong, cache entries can be deleted from
  https://travis-ci.org/ruby/ruby/caches (requires login).

- See `ccache(1)` manual page for the new environment variables.

- `ccache` thinks two compilations are not identical if they produce
  different diagnostics.  The -fno-diagnostics-color option is to
  prevent such cache missihts only because TTY is present / absent at
  the compilation time.

- In this changeset two "ccache --show-stats" invocations are inserted
  before and after the compilation to measure cache hit rates etc.

test_function.rb: loosen delta boundary

On osx build https://travis-ci.org/ruby/ruby/jobs/454309945,

```
1) Failure:

slept amount of time.
Expected |200 - 322| (122) to be <= 100.
```

but it succeeds on my macOS machine as is. So it seems that the boundary is
just too strict and prone to random failure by overload.

char is neither signed nor unsigned

read_escaped_byte() returns values of range -1...256. -1 indicates
error.  So the function basically expects char to be 0..255 range.
There is no such guarantee. `char` is not always unsigned.  We
need to explicitly declare chbuf to be unsigned char.

~(unsigned char) is not unsigned char

The unary ~ operator excercises integer promotion of the operand
_before_ actually applying bitwise complement (cf: ISO/IEC 9899:1990
section 6.3.3.3).  Which means `~buf[i]` is in fact
`(int)~(int)buf[i]`.

The problem is, when buf[i] is 0xFF:

buf[i]        0xFF
 (int)buf[i] 0x0000_00FF
~(int)buf[i] 0xFFFF_FF00 This is -256, out of unsigned char range.

The proposed fix is to change the char signed.  By doing so,

buf[i]        0xFF
      (signed char)buf[i]        0xFF
 (int)(signed char)buf[i] 0xFFFF_FFFF
~(int)(signed char)buf[i] 0x0000_0000 This is 0, does not overflow.

For some reason this very useful method was undocumented since it was added in

impossible before this change.

I've added a detailed example with sample code because it's one of the most
powerful tools to debug Ruby code and I believe very few people are aware of it
due to the lack of documentation.

numeric.c: avoid division by zero

In C, division by zero is undefined, even if the expression is double
(cf: ISO/IEC 9899:1990 section 6.3.5).  OTOH we have tests about such
operations and results, means we expect no exceptional situation shall
occur.  We need to carefully reroute the situation, and generate what
is needed.

See also: https://travis-ci.org/ruby/ruby/jobs/452680646#L2943

PS: Recently (last two decades), C have Annex. F document. It
normatively specifies that the division operator is IEEE 754's
division operator (cf: ISO/IEC 9899:1999 section F.3).  If we could
move to such newer version this could be no problem.  But that is not
possible today.

fix passing wrong `passed_bmethod_me`.

* vm_core.h: remove `rb_execution_context_t::passed_bmethod_me`
  and fix functions to pass the `me` directly.
  `passed_bmethod_me` was used to make bmethod (methods defined by
  `defined_method`). `rb_vm_invoke_bmethod` invoke `Proc` with `me`
  information as method frame (`lambda` frame, actually).
  If the proc call is not bmethod call, `passed_bmethod_me` should
  be NULL. However, there is a bug which passes wrong `me` for
  normal block call.

http://ci.rvm.jp/results/trunk-asserts@silicon-docker/1449470

This is because wrong `me` was remained in `passed_bmethod_me`
  (and used incorrectly it after collected by GC).

We need to clear `passed_bmethod_me` just after bmethod call,
  but clearing is not enough.

To solve this issue, I removed `passed_bmethod_me` and pass `me`
  information as a function parameter of `rb_vm_invoke_bmethod`,
  `invoke_block_from_c_proc` and `invoke_iseq_block_from_c` in vm.c.

* vm.c (invoke_iseq_block_from_c): the number of parameters is too
  long so that I try to specify `ALWAYS_INLINE`.

* vm.c (invoke_block_from_c_proc): ditto.

* vm_insnhelper.c (vm_yield_with_cfunc): now there are no pathes
  to use bmethod here.

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.

* thread.c (thread_do_start): copy `invoke_arg.proc.args` contents

  We don't need to keep Array and don't need to cancel using transient heap.

  parameter (rb_thread_t::invoke_arg::func::arg). However, a rubyspec test
  (thread_spec.c) passes an Array object and it expect to mark it.
  Clealy it is out of scope (misuse of `rb_thread_create` C-API). However,
  I'm not sure someone else has such kind of misunderstanding.
  So now we mark conservatively this (void *) arg with rb_gc_mark_maybe.

This misuse is found by this error log.

insns.def: avoid integer overflow

In these expressions `1` is of type `signed int` (cf: ISO/IEC
9899:1990 section 6.1.3.2). The variable (e.g. `num`) is of type
`rb_num_t`, which is in fact `unsigned long`.  These two expressions
then exercises the "usual arithmetic conversions" (cf: ISO/IEC
9899:1990 section 6.2.1.5) and both eventually become `unsigned long`.
The two unsigned expressions are then subtracted to generate another
unsigned integer expression (cf: ISO/IEC 9899:1990 section 6.3.6).
This is where integer overflows can occur.  OTOH the left hand side of
the assignments are `rb_snum_t` which is `signed long`.  The
assignments exercise the "implicit conversion" of "an unsigned integer
is converted to its corresponding signed integer" case (cf: ISO/IEC
9899:1990 section 6.2.1.2), which is "implementation-defined" (read:
not portable).

Casts are the proper way to avoid this problem.  Because all
expressions are converted to some integer types before any binary
operations are performed, the assignments now have fully defined
behaviour.  These values can never exceed LONG_MAX so the casts must
not lose any information.

Looking at the lines right above, it is clear than a blue sky

Fix TracePoint for nested iseq loaded from binary [Bug#14702]

When loading iseq from binary while a TracePoint is on, we need to
recompile instructions to their "trace_" variant. Before this commit
we only recompiled instructions in the top level iseq, which meant
that TracePoint was malfunctioning for code inside module/class/method
definitions.

* compile.c: Move rb_iseq_init_trace to rb_ibf_load_iseq_complete.
  It is called on all iseqs during loading.

* test_iseq.rb: Test that tracepoints fire within children iseq when
  using load_from_binary.

thread_pthread.c (native_ppoll_sleep): new eventfd (or pipe) for ubf

Relying on ubf_select + ubf_list for main thread is not
guaranteed to wake a process up as it does not acquire
sigwait_fd and all other threads may be sleeping.
native_cond_sleep and the sigwait_fd path are immune to TOCTOU
issues, but native_ppoll_sleep may have its wakeup stolen
by sigwait_fd sleeper and the RUBY_VM_INTERRUPTED check is
insufficient.

Note: for pthreads platforms without POSIX timers, this becomes
more expensive than Ruby 2.5, as six pipe FDs come into use.
Linux is best off with only two descriptors for eventfd.

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().

introduce TransientHeap. [Bug #14858]

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.

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().

process.c: implement rb_f_system without toggling ruby_nocldwait

Following how mjit_worker.c currently works, rb_f_system
now ensures the VM-wide waitpid lists is locked before
creating a new process via fork/vfork.

This ensures other rb_waitpid callers cannot steal work and
there are no possible race conditions from toggling
ruby_nocldwait without the use of atomics.

This sets us up for implementing MJIT process management
logic using normal Ruby APIs prepares us for VM-wide
asynchronous/event-base waitpid which can allow MJIT to
work without worker threads.

Take 2: set waitpid_state.pid on platforms w/o fork.

revisit more MJIT test skips

r65308 passed both trunk-mjit and trunk-mjit-wait CIs. MJIT copy job
looks working fine. Then this commit skips 5 more tests. Some of them
were skipped in a very early stage and may still need to be skipped, but
I want to confirm them since they haven't been changed for a long time.

And this prefers having inline information on `RubyVM::MJIT.enabled?`.
This commit makes it easier to confirm whether there's suspicious test
skip by RubyVM::MJIT.enabled? or not.

After this commit, tentatively we're not skipping tests for MJIT other
than `assert_no_memory_leak` ones.

Set the size of a new enumerator created by Enumerator#each with arguments to nil

When each() takes arguments, it is never safe to assume that the iteration
would repeat the same number of times as with each() without any
argument.  Actually, there is no way to get the exact number, so the
size should be set to nil to denote that.

try to remove some test skips for MJIT

Eric Wong made some effort to keep compatibility around fd with MJIT.
Also I'm hoping r65279 (and r65280) eliminates major MJIT bugs, so I
want to start solely testing MJIT. Other test skips branched by MJIT
enablement seemed reasonable to me.

NEWS: prefer advertising --jit option [ci skip]

In addition to `--enable=jit` and `--enable-jit`, we're going to ship
`--jit` as a short hand of it in Ruby 2.6.0.

That's because both --enable=jit and --enable-jit are super hard to
type everytime on command line, and I want make it easier to use so
that many people use it. First of all, `--enable=jit` is accidentally
added for consistency with `--disable=jit` and it's not added for human.

As it's a short hand, once JIT became enabled by default, the `--jit`
option would be removed after some deprecation warning period and only
`--enable=jit`/`--disable=jit` will survive. That being said, I still
think having `--jit` as a temporary short hand is valuable for the above
reasons.

vm_insnhelper.c: never cache getinstancevariable twice

We have several options to ensure there's no race condition between main
thread and MJIT thead about IC reference:

1) Give up caching ivar for multiple classes (or multiple versions of the
   same class) in the same getinstancevariable (This commit's approach)
2) Allocate new inline cache every time

Other ideas we could think of couldn't eliminate possibilities of race
condition.
In 2, it's memory allocation would be slow and it may trigger JIT
cancellation frequently. So 1 would be fast for both VM and JIT
situations.

ext/coverage/: add the oneshot mode

This patch introduces "oneshot_lines" mode for `Coverage.start`, which
checks "whether each line was executed at least once or not", instead of
"how many times each line was executed".  A hook for each line is fired
at most once, and after it is fired, the hook flag was removed; it runs
with zero overhead.

See: http://austingroupbugs.net/view.php?id=741

mjit_worker.c: suppress child process's output properly

Prior to this commit, some of parent process's output was unintentionally
suppressed. We couldn't suppress only child process's output with spawnvp.

Instead of that, this commit uses CreateProcess directly to redirect stdout
and stderr only for child process.

As it's dealing with HANDLE returned from CreateProcess, now waitpid macro
needs to CloseHandle it.

win32/win32.c: Introduce rb_w32_start_process which is designed for MJIT
worker. Other similar functions can't be used since they are using ALLOCV
that may trigger GC, which should be avoided on MJIT worker.

The format addresses are printed in are different if you use
`ObjectSpace.dump_all(output: :stdout)` vs.
`ObjectSpace.dump_all(output: :string)` (or `ObjectSpace.dump`) due to
differences in the underlying `vfprintf` implementation.

Visual C++ 12.0 doesn't have PRIxPTR.
Anyway we have our own vfprintf implementation BSD_vfprintf().
If you want to have portable vfprintf, replace it with BSD_vfprintf like

This change resolves most of major remaining MJIT bugs on mswin.
Since Visual Studio doesn't support generating pre-processed code

So we need to transform MJIT header using macro like this.

and cause conflict on link.
vm_insnhelper.c: ditto

add_spec.rb: skip unstable spec on mingw

This sometimes crashes mspec worker like
https://ci.appveyor.com/project/ruby/ruby/build/9806/job/37tx2atojy96227m

and it doesn't generate helpful output and it seems hard to fix it soon.
As AppVeyor is too unstable by too many factors, let me skip this
at least for a short term. until AppVeyor gets stable.

mjit.h: call compiled code immediately

after the first compilation on --jit-wait.

Previously the assignment to `func` didn't have meaning for the behavior,
and the compiled code wasn't called immediately after the synchronous
compilation. It wasn't intentional.

Fixing this issue without impacting performance without --jit-wait is
not so obvious. Adding branch or goto to call func in mjit_exec spoiled
the performance without --jit-wait. Instead of that, I called the func
inside mjit_wait_call() (former mjit_get_iseq_func()) which is never
inlined to mjit_exec(). Thanks to that, this commit has no impact for
normal performance.

mjit.c: ditto

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.

It solves partially https://bugs.ruby-lang.org/issues/14097

as a workaround to fix the build pipeline broken by r64824,
because optimizing Ruby should be prioritized higher than supporting unused jokes.

In the current build system, exceeding 200 insns somehow crashes C

*** No rule to make target 'note'.  Stop."
https://ci.appveyor.com/project/ruby/ruby/build/9725/job/co4nu9jugm8qwdrp
and on some of Linux environments like "cannot load such file -- stringio (LoadError)"

This commit removes "bitblt" and "trace_bitblt" insns, which reduces the
number of insns from 202 to 200 and fixes at least the latter build
failure. I hope this fixes the MinGW build failure as well. Let me
confirm the situation on AppVeyor CI.

Note that this is hard to fix because some MinGW environments (MSP-Greg's
MinGW CI on AppVeyor) don't reproduce this and some Linux environments
(including my local machine) don't reproduce it either. Make sure you
have the reproductive environment and confirm it's fixed when reverting
this commit.

insns.def: optimize & and | of Integer [experimental]

not optimizing Array#& and Array#| because vm_insnhelper.c can't easily
inline it (large amount of array.c code would be needed in vm_insnhelper.c)
and the method body is a little complicated compared to Integer's ones.
So I thought only Integer#& and Integer#| have a significant impact,
and eliminating unnecessary branches would contribute to JIT's performance.

vm_insnhelper.c: ditto

tool/transform_mjit_header.rb: make sure these instructions are inlined
on JIT.

compile.c: compile vm_opt_and and vm_opt_or.
id.def: define id for them to be used in compile.c and vm*.c
vm.c: track redefinition of Integer#& and Integer#|
vm_core.h: allow detecting redefinition of & and |

test/ruby/test_jit.rb: test new insns
test/ruby/test_optimization.rb: ditto

This is a kind of experimental thing but I'm committing this since the
performance impact is significant especially on Optcarrot with JIT.

  [Bug #15105]

There is a complicated story of this issue:
  Without this patch, IFUNC frame does not escaped. A IFUNC frame
  points to CFUNC ep as previous ep. However, CFUNC ep can be escaped
  because of making bindings of Ruby level frames.
  IFUNC's ep can points to invalidated ep and `rb_iter_break()` will
  fail. This is why `any?` fails.

I introduce a `union` 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. It is plan to introduce a `union!` method as well.

Tests and documentation are included.

process.c (waitpid_cleanup): unconditionally remove from waiters

This is the safer option, as there seems to be cases where checking
waitpid_state.ret is insufficient in ensure.  I'm not 100% sure
why this is, but this change was required for my work-in-progress
Thread::Light patch series, too...

Hash#merge, merge!, and update could merge exactly two hashes.
Now, they accepts zero or more hashes as arguments so that it can merge
hashes more than two.

because cc->call is NULL by default and it is not overridden by

Make qsort_r() flavor detecting work if qsort_r() is a macro

On FreeBSD we're going to switch to the GNU-ish version of qsort_r().
POSIX is also considering standardizing that one. To prevent faulty
calls, we have a macro in place to throw a compiler error if a BSD-style
qsort_r() call is performed on a patched system. Such an approach tends
to be permitted by POSIX.

The configure check we have in Ruby would fail if qsort_r() is a
function macro. Add parentheses around it to prevent macro expansion and
force the declaration of a prototype.

thread.c (rb_thread_atfork): reinitialize current th->interrupt_lock

Another thread may be holding th->interrupt_lock while our
current thread calls fork.  Therefore we must reinitialize our
own th->interrupt_lock in the child process because the owner
of the lock is only in the parent.  The original parent process
is unaffected.  We cannot destroy the lock while it has an unknown
state, either, so some implementations can leak a small amount
of memory, here (NPTL won't).

fiber: fix crash on GC after forking

Remove the remainder of ROOT_FIBER_CONTEXT use and unnecessary
differences between the root and non-root fiber.  This makes
it easier to follow new root fiber at fork time.

Multiple sources of truth often leads to bugs, as in this case.
We can determinte root fiber by checking a fiber against the root_fiber
of its owner thread.  The new `fiber_is_root_p' function
supports that.

Now, we can care only about free-ing/recycling/munmap-ing stacks
as appropriate.

cont.c (fiber_memsize): do not rely on ROOT_FIBER_CONTEXT

We can check if the fiber we're interested in is the
th->root_fiber for the owner thread, so there is no need to use
ROOT_FIBER_CONTEXT.

Note: there is no guarantee th->ec points to
&th->root_fiber->cont.saved_ec, thus vm::thread_memsize may not
account for root fiber correctly (pre-existing bug).

share VM stack between threads and fibers if identical in size

ec->vm_stack is always allocated with malloc, so stack cache for
root fiber (thread stack) and non-root fibers can be shared as
long as the size is the same.  The purpose of this change is to
reduce dependencies on ROOT_FIBER_CONTEXT.

when catch_except_p is false and insn.always_leaf? is true (never makes

On Optcarrot, unfortunately this didn't have measureable performance impact.
But still this is a good direction since it becomes much faster when
marking all insns as always leaf.

bare_instructions.rb: add `#always_leaf?` that indicates the insn can
always be considered as leaf. Using dynamic leaf for JIT would be hard
since it requires to discard outdated code somehow.

process.c: simplify SIGCHLD-based waitpid

Introduce a new rb_thread_sleep_interruptible that does not
execute interrupts before sleeping.  Skipping the interrupt
check before sleep is required for out-of-GVL ruby_waitpid_all
to function properly when setting waitpid_state.ret

Now that ubf_select can be called by the gvl.timer thread
without recursive locking gvl.lock, we can safely use
rb_threadptr_interrupt to deal with waking up sleeping
processes,

thread_pthread.c: avoid lock ping-pong in do_gvl_timer & ubf_select

This simplifies the locking logic somewhat.

While we're at it, designate_timer_thread is worthless in
ubf_select because gvl_acquire_common already guarantees there
is a gvl.timer if gvl->waitq is populated.

In the future (for auto-fiber), this will allow using
th->unblock.func for rb_waitpid callers (via rb_sigchld_handler).

thread.c: check interrupts explicitly in select/ppoll blocking regions

The logic around blocking_region_begin is confusing to me,
but the goal of this patch is to ensure rb_sigwait_fd_get
and rb_sigwait_fd_put are matched.

In other words, we don't want a thread to hold sigwait_fd
forever if an exception is raised while calling select()
or ppoll().

test/ruby/test_io.rb (test_recycled_fd_close): Linux workaround

Arch Linux CI still seems to timeout on this test...

Note, I can't reproduce the failures in these tests on a
FreeBSD 11.1 VM while infinite-looping, even without the
"th.join(0.001)".  It doesn't seem related to the use of
rb_wait_for_single_fd (r64529).

thread_pthread.c: main thread always gets hit by signals

We need to ensure Signal.trap handlers can function if the main
thread is sleeping after a subthread has grabbed sigwait_fd,
but later exited.

Consider the following timeline:

main_thread             sub-thread
-----------------------------------------
Signal.trap() { ... }
                        get sigwait_fd
                        ppoll on sigwait_fd
native_cond_sleep
(via pthread_cond_wait)
                        ppoll times-out
			put sigwait_fd
                        sub-thread exits

only thread alive
SIGNAL HITS

The problem is pthread_cond_wait cannot return EINTR,
so we can never run the Signal.trap handler.  So we
will avoid using native_cond_sleep in the main thread
and always use ppoll to sleep when in the main thread.
This can guarantee the main thread remains aware of
signals; even if it cannot safely read off sigwait_fd

thread.c: use rb_hrtime_t scalar for high-resolution time operations

Relying on "struct timespec" was too annoying API-wise and
used more stack space.  "double" was a bit wacky w.r.t rounding
in the past, so now we'll switch to using a 64-bit type.

Unsigned 64-bit integer is able to give us over nearly 585
years of range with nanoseconds.  This range is good enough
for the Linux kernel internal time representation, so it
ought to be good enough for us.

This reduces the stack usage of functions while GVL is held
(and thus subject to marking) on x86-64 Linux (with ppoll):

rb_wait_for_single_fd    120 => 104
	do_select                120 => 88

eventfd on Linux.

The code fragments that initializes coverage data were scattered into

To remove this cross-cutting concern, this change moves the allocation
from "coverage" function of parse.y to "rb_iseq_new_top" of iseq.c.
For the sake, parse.y just counts the line number of the original source
code, and the number is passed via rb_ast_body_t.

thread.c (rb_reset_coverages): remove coverage counters from all ISeqs

When coverage measurement is enabled, the compiler makes each iseq have
a reference to the counter array of coverage.
Even after coverage measurement is disabled, the reference is kept.
And, if coverage measurement is restarted, a coverage hook will increase
the counter.  This is completely meaningless; it brings just overhead.

To remove this meaninglessness, this change removes all the reference
when coverage measuement is stopped.

It's possible for the ubf_list_head to be populated with dead
threads at fork or the ubf_list_lock to be held, so reinitialize
both at startup.

And while we're at it, use a static initializer at startup
to save a library call and kill some ifdef.

spec/ruby/core/io/select_spec.rb: workaround stuck IO.select

Under pipe page memory pressure on Linux, a pipe may only be
created with a single buffer[1].  And as of Linux v4.18, the
fs/pipe.c::pipe_poll callback does not account for merging
done in fs/pipe::pipe_write; only the number of usable buffers
in the pipe.  Thus it is possible for a pipe to be writable
(if only by a small amount) despite IO.select saying it is not.

With the default 16384 /proc/sys/fs/pipe-user-pages-soft value
and the pipe having 16 pages of buffers, this issue is trivially
reproducible by creating 1024 pipes in a background process
before running the spec:

$ ulimit -n 2053 # or something higher
  $ ./miniruby -e '1024.times.map { IO.pipe }; sleep' &
  $ make test-spec MSPECOPT=spec/ruby/core/io/select_spec.rb

So, we create a new pipe we never write to for testing
writability of IO.select.  This may cause the test to fail with
ENFILE on an overloaded system, but at least that's an obvious
failure (unlike having a test get stuck).  This should reduce
failures on our overloaded CI machines:

thread_sync.c (rb_mutex_sleep): disable interrupt checking in ensure

This is needed to reliably fix ConditionVariable#wait on Thread#kill
[Bug #14999] because there is still a chance an interrupt could fire
and prevent lock acquisition after an ensure statement.

Arguably, rb_mutex_lock itself should be uninterruptible, but that
already prevents bootstraptest/test_thread.rb from completing and
probably breaks existing use cases.

For reference, POSIX expressly forbids EINTR from pthread_mutex_lock.

thread_pthread.c: reset timeslice delay when uncontended

This matches the behavior of old timer thread more closely
and seems to fix [Bug #14999] when limited to a single CPU.
I cannot reproduce the error on a multi-core system unless
I use schedtool to force affinity to a single CPU:

schedtool -a 0x01 -e make test-spec \
	MSPECOPT='-R1000 spec/ruby/library/conditionvariable/wait_spec.rb'

While it may be good enough to pass the spec, I don't have
huge degree of confidence in the interrupt handling robustness
under extremely heavy load (these may be ancient bugs, though).

thread.c (sleep_*): reduce the effect of spurious interrupts

Spurious interrupts from SIGCHLD cause Mutex#sleep (via
ConditionVariable#wait) to return early and breaks some use
cases.  Since these are outside the programs's control with
MJIT, we will only consider pending interrupts (e.g. those
from Thread#run) and signals which cause a Ruby-level Signal.trap
handler to fire as "spurious" wakeups.

If an exception is raised inside Mutex#sleep (via ConditionVariable#wait),

However, who owns the mutex at that point does not matter.  What
matters is the Mutex is usable after an exception occurs.

* thread_sync.c (rb_mutex_synchronize): only unlock if we own the mutex

* spec/ruby/library/conditionvariable/wait_spec.rb: only test lock
  usability after thread kill.  Who owns the lock at any
  particular moment is an implementation detail which we cannot

process.c: defaults to close_others false

Arbitrarily closing file descriptors on exec breaks use cases
where a Ruby process sets up a descriptor for non-Ruby children
to use.  For example, the "rake foo" target may spawn any number
of subprocesses (Ruby or not) which depends on parsing the "FOO"
environment variable for out_fd:99 and writing to foo.out

FOO=out_fd:99 rake foo 99>>foo.out

Unfortunately, this introduced one incompatibility in
test/lib/test/unit.rb and it now requires explicitly setting
IO#close_on_exec=true

thread_sync.c (rb_mutex_lock): acquire lock before being killed

We (the thread acquiring the mutex) need to acquire the mutex
before being killed to work with ConditionVariable#wait.

Thus we reinstate the acquire-immediately-after-sleeping logic
from pre-r63711 while still retaining the
acquire-after-checking-for-interrupts logic from r63711.

test/net/imap/test_imap.rb (test_exception_during_idle): kill infinite looper

It is possible for Mutex#sleep (via ConditionVariable#wait)
to prematurely wake up under MJIT (because Mutex#sleep can't
handle spurious wakeups).  This affects @idle_done_cond in
Net::IMAP#idle and means the response handler may never
set `in_idle' to `true`.

In any case, ensure the infinite looping `raiser' thread
stops running when the test is done.

Will work on reducing the effect of spurious wakeups from
MJIT...

spec/ruby/optional/capi/io_spec.rb: fix fragile spec from unpredictable errno

rb_io_wait_readable and rb_io_wait_writable depend on the TSD
errno value.  Due to the recent changes in r64352-r64353 to
restructure GVL, errno could be set to EAGAIN from the signal
self-pipe and cause the rb_io_wait_readable spec to block
unexpectedly.  This should fix rubyspec timeouts on Solaris:

I'm not sure what's causing this failure in Solaris and only

timing (similar to old timer-thread) can solve the issue.

thread_pthread: use POSIX timer or thread to get rid of races

This closes race condition where GVL is uncontended and a thread
receives a signal immediately before calling the blocking
function when releasing GVL:

1) check interrupts
	2) release GVL
	3) blocking function

If signal fires after 1) but before 3), that thread may never
wake up if GVL is uncontended

We also need to wakeup the ubf_list unconditionally on
gvl_yield; because two threads can be yielding to each other
while waiting on IO#close while waiting on threads in IO#read or
IO#gets.

Support optional inherit argument for Module#method_defined?

Module has many introspection methods for methods and constants that
either return an array or return true or false for whether the method
or constant is defined. Most of these methods support an optional
argument that controls whether to consider inheritance.  Currently,
the following Module methods support such a argument:

* const_defined?
* constants
* instance_methods
* private_instance_methods
* protected_instance_methods
* public_instance_methods

and the following methods do not:

* method_defined?
* private_method_defined?
* protected_method_defined?
* public_method_defined?

This patch supports such an argument for the *method_defined?
methods.

While you can currently work around the lack of support via:

mod.instance_methods(false).include?(:method_name)

This patch allows the simpler and more efficient:

mod.method_defined?(:method_name, false)

One case where you want to exclude inheritance when checking
for a method definition is when you want to replace a method
that may already exist.  To avoid a verbose warning, you want
to remove the method only if it is already defined:

remove_method(:foo) if method_defined?(:foo, false)
  define_method(:foo){}

You can't call remove_method without checking for the method
definition, as that can raise a NameError, and you don't want
to include inheritance because remove_method will still raise
a NameError if the method is defined by an ancestor and not
by the module itself.

In the r64285's structure, we needed to publish some variables with

in mjit.o (or old mjit_worker.o), and it was hard.

So I chose an approach similar to vm*.c for mjit.c and mjit_worker.c.
I believe mjit_compile.c is still nice to be separated.

After this commit, I'll remove the mjit_ prefix again...

mjit_worker.c: carve out worker-related code

The motivation of this change is to make sure rb_funcall or GC-related

functions are used in some places and I believe it's partly because it's
hard to identify which part is called on MJIT worker thread.

Now, mjit.c is safe to use them but we know we need to safely deal with
mjit_compile.c, mjit_worker.c and mjit_internal.h.

Actually we would be able to move it only when method call (of

can happen.

This degrades performance. Optcarrot fps becomes...
before: 71.78976052783555
after: 67.65429356624131

I think I can lazily move it and fix the performance issue, even
improving the performance for the situation catch table exists.

common.mk: "make check" now runs test-spec

Currently there are many "make" targets for testing: test, test-all,
check, exam, etc.
To make it simple, this change makes "make check" run all tests.
"make exam" is just an alias to "make check".
If a new test suite is added in future, "make check" should include it
(unless it takes too much time...)
[Feature #14187]

Also, this introduces "make test-short" as an alias to "make test".
I believe "make test" should equal to "make check", but there is

insns.def (invokesuper): remove a dummy receiever flag hack for ZSUPER

This is just a refactoring.

The receiver of "invokesuper" was a boolean to represent if it is ZSUPER
or not.  This was used in vm_search_super_method to prohibit ZSUPER call
in define_method. (It is currently prohibited because of the limitation
of the implementation.)

This change removes the hack by introducing an explicit flag,
VM_CALL_SUPER, to signal the information.  Now, the implementation of
"invokesuper" is consistent with "send" instruction.

net/http, net/ftp: skip SSL/TLS session resumption tests

Due to a bug in OpenSSL 1.1.0h[1] (it's only in this specific version;
it was introduced just before the release and is already fixed in their
stable branch), the callback set by SSLContext#session_new_cb= does not
get called for clients, making net/http and net/ftp not attempt session
resumption.

Let's disable the affected test cases for now. Another option would be
to fallback to using SSLSocket#session as we did before r64234. But
since only a single version is affected and hopefully a new stable
version containing the fix will be released in near future, I chose not
to add such workaround code to lib/.

spec/ruby/library/socket/*: more FreeBSD fixes

FreeBSD portability notes:

Loopback connections are not instantaneous (unlike Linux), so
non-blocking read-after-write MUST check for readability via
IO.select or IO#wait_readable before attempting non-blocking
recv/read operations.

IPv6 seems favored, so we'll get "::" instead of "0.0.0.0"

Some constants are different or obsolete, so that should be
self-explanatory.

There are still other failures I or somebody else needs to get
to when we have time and feel like dealing with spec DSL:

net/http, net/ftp: fix session resumption with TLS 1.3

When TLS 1.3 is in use, the session ticket may not have been sent yet
even though a handshake has finished. Also, the ticket could change if
multiple session ticket messages are sent by the server. Use
SSLContext#session_new_cb instead of calling SSLSocket#session
immediately after a handshake. This way also works with earlier protocol
versions.

win32/Makefile.sub: escape `=` in MJIT cflags

Since `=` is considered as delimiter in `()` of `for`, having
`-DRUBY_DEVEL=1` in CPPFLAGS had resulted in:

#define MJIT_OPTFLAGS "-DMJIT_HEADER", \
   "-DRUBY_DEVEL", \
   "1", \

Even escaped `for %I in (... -DRUBY_DEVEL^=1)` does not yield an
expected result. This commit is a workaround for this issue.

After this commit, mjit_config.h will have:

#define MJIT_OPTFLAGS "-DMJIT_HEADER", \
   "-DRUBY_DEVEL" MJIT_CONFIG_ESCAPED_EQ "1", \

And C macro resolves MJIT_CONFIG_ESCAPED_EQ to "=".

enumerator.c: Introduce Enumerator::ArithmeticSequence

This commit introduces new core class Enumerator::ArithmeticSequence.
Enumerator::ArithmeticSequence is a subclass of Enumerator, and
represents a number generator of an arithmetic sequence.

After this commit, Numeric#step and Range#step without blocks
returned an ArithmeticSequence object instead of an Enumerator.

This class introduces the following incompatibilities:

- You can create a zero-step ArithmeticSequence,
  and its size is not ArgumentError, but Infinity.
- You can create a negative-step ArithmeticSequence from a range.

thread_pthread: stop trying to deal with cancellation

We don't use pthreads cancellation ourselves and it's painful to
use correctly.  Any cancelled threads would break
vm->living_threads, GVL, thread_sync.c, autoload, etc...

So don't bother caring; because we can't stop rogue extensions
from completely breaking the VM in other ways, either.

thread_pthread.c (native_sleep): reduce ppoll sleeps

By holding into sigwait_fd until after we acquire GVL, we can
hit the faster native_cond_sleep path instead of ppoll when
another thread wants to start sleeping.  ppoll-ing on sigwait_fd
isn't really useful in program where GVL is contended

This also allows reducing vm->gvl.lock mutex contention on
waitpid sleep migrations.

common.mk: stop building MJIT min header for mswin

Since it's impossible to leave macro when preprocessing C source file
with cl.exe, I decided to create precompiled header on Ruby's build time
instead.

We're not doing it for non-mswin environment for 2 reasons:
1) Precompiled header may not be able to be used when CC is upgraded.
2) We need to create as many precompiled headers as the patterns of
   compile options. (Probably only 2, for with and without --jit-debug)

I'll ignore them for mswin for now, and solve it later by including CC
version and --jit-debug information in precompiled header filename.
After that, non-mswin environment may follow it to simplify build system.

Makefile.in: ditto

mjit.c: allow using MJIT header in build directory

when $MJIT_SEARCH_BUILD_DIR is set.

If prefix path is owned by root, `make install` needs to be run by root.
But in general we don't want to run `make test-all`, and also running
`make test-all` currently fails due to permission tests of rdoc and rubygems.
Thus, prior to this commit, specifying a prefix like "/usr/local" could
mean there was no way to pass test-all.

So we should not depend on `make install` for `make test-all`. Thus I
reverted r64104 and r64103, and applied this workaround to pass `make
test-all` without `make install`.

thread_pthread: remove timer-thread by restructuring GVL

To reduce resource use and reduce CI failure; remove
timer-thread.  Single-threaded Ruby processes (including forked
children) will never see extra thread overhead.  This prevents
glibc and jemalloc from going into multi-threaded mode and
initializing locks or causing fragmentation via arena explosion.

The GVL is implements its own wait-queue as a ccan/list to
permit controlling wakeup order.  Timeslice under contention is
handled by a designated timer thread (similar to choosing a
"patrol_thread" for current deadlock checking).

There is only one self-pipe, now, as wakeups for timeslice are
done independently using condition variables.  This reduces FD
pressure slightly.

Signal handling is handled directly by a Ruby Thread (instead
of timer-thread) by exposing signal self-pipe to callers of
rb_thread_fd_select, native_sleep, rb_wait_for_single_fd, etc...
Acquiring, using, and releasing the self-pipe is exposed via 4
new internal functions:

1) rb_sigwait_fd_get - exclusively acquire timer_thread_pipe.normal[0]

2) rb_sigwait_fd_sleep - sleep and wait for signal (and no other FDs)

3) rb_sigwait_fd_put - release acquired result from rb_sigwait_fd_get

4) rb_sigwait_fd_migrate - migrate signal handling to another thread
                           after calling rb_sigwait_fd_put.

rb_sigwait_fd_migrate is necessary for waitpid callers because
only one thread can wait on self-pipe at a time, otherwise a
deadlock will occur if threads fight over the self-pipe.

TRAP_INTERRUPT_MASK is now set for the main thread directly in
signal handler via rb_thread_wakeup_timer_thread.

Originally, I wanted to use POSIX timers
(timer_create/timer_settime) for this.  Unfortunately, this
proved unfeasible as Mutex#sleep resumes on spurious wakeups and
test/thread/test_cv.rb::test_condvar_timed_wait failed.  Using
pthread_sigmask to mask out SIGVTALRM fixed that test,  but
test/fiddle/test_function.rb::test_nogvl_poll proved there'd be
some unavoidable (and frequent) incompatibilities from that
approach.

Finally, this allows us to drop thread_destruct_lock and
interrupt current ec directly.

We don't need to rely on vm->thread_destruct_lock or a coherent
vm->running_thread on any platform.  Separate timer-thread for
time slice and signal handling is relegated to thread_win32.c,
now.

mjit.c: introduce JIT compaction [experimental]

When all compilation finishes or the number of JIT-ed code reaches
--jit-max-cache, this compacts all generated code to a single .so file
and re-loads all methods from it.

In the future, it may trigger compaction more frequently and/or limit
the maximum times of compaction to prevent unlimited memory usage.
So the current behavior is experimental, but at least the performance
improvement in this commit won't be removed.

=== Benchmark ===
In this benchmark, I'll compare following four conditions:

* trunk: r64082
* trunk JIT: r64082 w/ --jit
* single-so JIT: This commit w/ --jit
* objfcn JIT: This branch https://github.com/k0kubun/ruby/tree/objfcn w/ --jit,
  which is shinh's objfcn https://github.com/shinh/ruby/tree/objfcn rebased from this commit

this branch https://github.com/k0kubun/discourse/commits/benchmark2 forked from discourse
v1.8.11 to support running trunk.

1. Run ruby script/bench.rb to warm up profiling database
2. Run RUBYOPT='--jit-verbose=1 --jit-max-cache=10000' RAILS_ENV=profile bin/puma -e production
3. WAIT 5-15 or so minutes for all jitting to stop so we have no cross talk

98 and 100% are not slower than that.

So now it's a little harder to say "MJIT slows down Rails applications".
Probably I can close [Bug #14490] now. Let's start improving it.

fix range check for Hangul jamo trailers in Unicode normalization

* lib/unicode_normalize/normalize.rb: Fix the range check for trailing
  Hangul jamo characters in Unicode normalization. Different from
  leading or vowel jamos, where LBASE and VBASE are actual characters,
  a value equal to TBASE expresses the absence of a trailing jamo.
  This fix is technically correct, but there was no bug because
  the regular expressions in lib/unicode_normalize/tables.rb
  eliminate jamos equal to TBASE from normalization processing.

* test/test_unicode_normalize.rb: Add preventive test
  test_no_trailing_jamo based on
  https://github.com/python/cpython/commit/d134809cd3764c6a634eab7bb8995e3e2eff14d5

thread.c (blocking_region_end): clear ubf before unregister_ubf_list

If we keep ubf set after unregistering, there is a window for
other threads (including timer thread) to put this thread back
on the ubf_list right away.  Entering ubf_list unexpectedly
after GVL acquisition may cause spurious wakeup and trigger
unexpected behavior.

Finally, clear ubf before acquiring GVL, to since ubf is useless
during GVL acquisition anyways and we don't want to waste cycles
in other threads calling ubf for useless work.

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.

Just refactoring.  Despite its name, the function does NOT return a

it follows the precedeint "rb_ary_modify_check", and is definitely

purpose.

I renamed it instead of adding a new one because I'm not sure about the
impact for the performance by increasing the switch branches in mjit_exec.

cont.c (ec_switch): prevent delayed/missed trap interrupt race

timer-thread may set trap interrupt with rb_threadptr_check_signal
at any time independent of GVL.  This means timer-thread may set
the trap interrupt flag on the previous execution context; causing
the flag to be unnoticed until a future ec switch (or lost
completely if the ec is done).

Note: I avoid relying on th->interrupt_lock here and use
atomics because we won't be able to rely on it for proposed lazy
timer-thread [Misc #14937].

This regression affects Ruby 2.5 as it was introduced by moving
interrupt_flag to `ec' which is an unstable pointer.  Ruby <= 2.4
was unaffected because vm->main_thread->interrupt_flag never
changed.

webrick: Support bcrypt password hashing

This adds a password_hash keyword argument to
WEBrick::HTTPAuth::Htpasswd#initialize.  If set to :bcrypt, it
will create bcrypt hashes instead of crypt hashes, and will
raise an exception if the .htpasswd file uses crypt hashes.

If :bcrypt is used, then instead of calling
BasicAuth.make_passwd (which uses crypt),
WEBrick::HTTPAuth::Htpasswd#set_passwd will set the bcrypt
password directly.  It isn't possible to change the
make_passwd API to accept the password hash format, as that
would break configurations who use Htpasswd#auth_type= to set
a custom auth_type.

This modifies WEBrick::HTTPAuth::BasicAuth to handle checking
both crypt and bcrypt hashes.

There are commented out requires for 'string/crypt', to handle
when String#crypt is deprecated and the undeprecated version is
moved to a gem.

There is also a commented out warning for the case when
the password_hash keyword is not specified and 'string/crypt'
cannot be required.  I think the warning makes sense to nudge
users to using bcrypt.

I've updated the tests to test nil, :crypt, and :bcrypt values
for the password_hash keyword, skipping the bcrypt tests if the
bcrypt library cannot be required.

mjit.c: handle memory allocation failure

which was missing in r64033.

Prior to r64033, memory allocation failure had been checked by
TRY_WITH_GC and handled by rb_memerror. But calling rb_memerror on MJIT
worker is problematic since it does EC_JUMP_TAG in the end. Threads
except Ruby's main thread must not use it.

zlib (rb_gzreader_getc): localize and return cbuf directly

No point in having a long-lived cbuf in "struct gzfile"
since GZFILE_CBUF_CAPA is smaller than RSTRING_EMBED_LEN_MAX
(even on 32-bit).  We can also have rb_econv_convert write
directly to the return value instead of an intermediate buffer.

This brings "struct gzfile" from 264 to 256 bytes on 64-bit
systems to avoid taking an additional cache line.

Include the alternative malloc header instead of malloc.h

This commit fixes a build error on systems that have
`malloc_usable_size` but also enable jemalloc via `--with-jemalloc`.
For example, Ubuntu Precise defines `malloc_usable_size` in malloc.h, so
gc.c will include malloc.h.  This definition conflicts with jemalloc's
definition, so the following error occurs:

```
compiling gc.c
compiling hash.c
In file included from gc.c:50:0:
/usr/include/malloc.h:152:15: error: conflicting types for 'malloc_usable_size'
/usr/include/jemalloc/jemalloc.h:45:8: note: previous declaration of 'malloc_usable_size' was here
cc1: warning: unrecognized command line option "-Wno-self-assign" [enabled by default]
cc1: warning: unrecognized command line option "-Wno-constant-logical-operand" [enabled by default]
cc1: warning: unrecognized command line option "-Wno-parentheses-equality" [enabled by default]
cc1: warning: unrecognized command line option "-Wno-tautological-compare" [enabled by default]
```

Since jemalloc always defines `malloc_usable_size`, this patch just
includes the jemalloc header instead of malloc.h if it's available.

timer_thread: do not close pipes around fork

There's actually no need to close the pipes used by the
sleepy timer thread before forking, only to stop the timer
thread itself.

Instead, we only close the parent pipes in the child process,
either via close-on-exec flag or when reinitializing the timer
thread.

This change will be necessary when we allow
rb_wait_for_single_fd and rb_thread_fd_select to wait on the
timer_thread_pipe.normal[0] directly and eliminate timer thread.

I don't anticipate compatibility problems with this change
alone.

Remove redundant code in the compiler.

During instruction translation (linked list -> iseq generation), we can
treat `TS_VALUE` and `TS_ISEQ` the same as they are just embedded in the
generated sequences.  The only difference between `TS_ISE` and `TS_IC`
is that an inline storage entry may contain a markable `VALUE` pointer
at some point, so we need to flag the iseq as containing markable
objects.

mjit: get rid of memory leak in pause+resume loop

pthread_atfork is not idempotent and repeatedly calling it
causes it to register the same hook repeatedly; leading to
unbound memory growth.

Ruby already has a (confusing-named) internal API for to call
in the forked child process: rb_thread_atfork
Call the MJIT child_after_fork hook inside that to prevent
unbound growth with the following loop:

loop do
      RubyVM::MJIT.pause
      RubyVM::MJIT.resume

thread.c (ruby_ppoll): improve timespec to msec conversion

Round up non-zero <1ms timeouts to 1ms and use INT_MAX instead
of infinite (-1) for extremely large timeouts.  All of our
ppoll/select callers are able to handle spurious wakeups,
anyways.

This avoids excessive CPU usage and busy waits with short
timeouts to rb_wait_for_single_fd.

CPU usage with the following script is significantly reduced
for systems with "#undef HAVE_PPOLL":

require 'io/wait'
    r, w = IO.pipe
    Thread.new { loop { r.wait_readable(0.000001) } }.join(5)
    exit!(0)

Low-resolution in poll(2) still sucks, though...

Note: I don't see the value in making a similar change to
time_timeval of a <1us sleep is attempted because of GVL
release and syscall latency.

Optimize Time.utc

Time.utc uses timegmw() and it uses leap second information.
If the given time is larger than known_leap_seconds_limit, it calls
find_time_t, which uses localtime(3) and calls stat(2) in it.

This patch avoid it by setting known_leap_seconds_limit to 0 if the timezone doesn't have leapsecond information (if no leap second is found "now", I assume the timezone doesn't have leapsecond information).

Before:
% time ./miniruby --disable-gem -e'time = Time.now; year = time.year; month = time.month; day = time.day; hour = time.hour; min = time.min; sec = time.sec + time.subsec; i = 0; while i < 100000; ::Time.utc(year, month, day, hour, min, sec); i += 1; end'

thread_pthread.c (native_thread_destroy): clear native TSD pointer

mwrap <https://80x24.org/mwrap/> interposes malloc functions and
checks for GVL existence to determine Ruby source locations of
malloc calls.  pthread_getattr_np (from get_stack) may call
realloc to get the CPU set size; so when using the thread-cache,
ruby_thread_has_gvl_p() may hit a false positive on reused
threads with lingering rb_thread_t in thread-specific data.

This was causing mwrap to call rb_source_location_cstr() and
crash because it was pointed to a zero ec->cfp->iseq.

hijack SIGCHLD handler for internal use

Use a global SIGCHLD handler to guard all callers of rb_waitpid.
To work safely with multi-threaded programs, we introduce a
VM-wide waitpid_lock to be acquired BEFORE fork/vfork spawns the
process.  This is to be combined with the new ruby_waitpid_locked
function used by mjit.c in a non-Ruby thread.

Ruby-level SIGCHLD handlers registered with Signal.trap(:CHLD)
continues to work as before and there should be no regressions
in any existing use cases.

Splitting the wait queues for PID > 0 and groups (PID <= 0)
ensures we favor PID > 0 callers.

The disabling of SIGCHLD in rb_f_system is longer necessary,
as we use deferred signal handling and no longer make ANY
blocking waitpid syscalls in other threads which could "beat"
the waitpid call made by rb_f_system.

We prevent SIGCHLD from firing in normal Ruby Threads and only
enable it in the timer-thread, to prevent spurious wakeups
from in test/-ext-/gvl/test_last_thread.rb with MJIT enabled.

I've tried to guard as much of the code for RUBY_SIGCHLD==0
using C "if" statements rather than CPP "#if" so to reduce
the likelyhood of portability problems as the compiler will
see more code.

We also work to suppress false-positives from
Process.wait(-1, Process::WNOHANG) to quiets warnings from
spec/ruby/core/process/wait2_spec.rb with MJIT enabled.

Lastly, we must implement rb_grantpt for ext/pty.  We need a
MJIT-compatible way of supporting grantpt(3) which may spawn
the `pt_chown' binary and call waitpid(2) on it.

glibc doesn't support static linking, so we guard on that.

Maybe other platforms will need this, too.

parse.y: Fix locations of none and mid-rule actions

When an empty rule or a mid-rule action is reduced,
`YYLLOC_DEFAULT` is called with the third parameter to be zero.
If we use `RUBY_SET_YYLLOC_OF_NONE` to set their locations,
sometimes the end position of NODE indicates a blank.
For example, `a.b ;` generates `NODE_CALL (line: 1, location: (1,0)-(1,4))*`,
whose end position indicates a blank.

This is because of the following reasons:

* `NODE_CALL` is created when `primary_value call_op operation2 opt_paren_args` is
  reduced to `method_call`.
* `opt_paren_args` is `none`.
* `yylex` is called and `lex.pbeg` moves before `none` is reduced, so
  the beginning position of `none` does not match with the end position of `operation2`.

To fix locations, use `YYRHSLOC(Rhs, 0)` in `YYLLOC_DEFAULT`
(0 "refers to the symbol just before the reduction").

By this change, the bottom of the location stack would be referenced,
so initialize the bottom with `RUBY_SET_YYLLOC_OF_NONE` in `%initial-action`.

rb_vm_insn_addr2insn: use st to perform addr2insn mapping

The current VM_INSTRUCTION_SIZE is 198, so the linear search
painful during a major GC phase.

I noticed rb_vm_insn_addr2insn2 showing up at the top of some
profiles while working on some malloc-related stuff, so I
decided to attack it.

Most notably, the benchmark/bm_vm3_gc.rb improves by over 40%:

Use `Net::HTTPClientException` instead of `Net::HTTPServerException`

`Net::HTTPServerException` has been deprecated since r63590. [Bug #14688]
And `net/http/responses.rb` uses the deprecated constant, so Ruby warns of the deprecation.

Example:

```bash
$ ruby -r net/http -e ''
/home/pocke/.rbenv/versions/trunk/lib/ruby/2.6.0/net/http/responses.rb:22: warning: constant Net::HTTPServerException is deprecated
```

This change suppresses the warning.

`int isnan(double)` is a POSIXism

- `isnan` is something relatively new.  We need to provide one for
  those systems without it.  However:
- X/Open defines `int isnan(double)`. Note the `int`.
- C99 defines `isnan(x)` to be a macro.
- C++11 nukes them all, undefines all the "masking macro"s, and
  defines its own `bool isnan(double)`.  Note the `bool`.
- In C++, `int isnan(double)` and `bool isnan(double)` are
  incompatible.
- So the mess.

spec/ruby: fix RUBY_DESCRIPTION check with JIT enabled

`make test-spec` adds `-r./$(arch)-fake` to pass header options.
But the $(arch)-fake.rb unexpectedly modifies RUBY_DESCRIPTION and it
always drops +JIT from it since the fake.rb is built with BOOTSTRAPRUBY,
which can be miniruby. miniruby can't find MJIT header and thus
mjit_init_p is always FALSE.

So, to pass `make test-spec` with JIT enabled, we can't use
RUBY_DESCRIPTION.

thread_pthread.c: enable thread cache by default

Since r62466 ("thread_pthread.c: shorten and fix thread cache implementation"),
our thread cache is no longer buggy with programs using fork.
This makes significant improvements in vm_thread_alive_check1
and vm_thread_create_join benchmarks and does not introduce
regressions.

Unlike old thread cache, I've changed the cache to only last 3
seconds since per-thread setup in most programs rarely takes
more than a few milliseconds to re-establish things like network
connections.  This is configurable by changing the THREAD_CACHE_TIME
variable.

I hope this allows users to simplify their code by removing the
need for thread pools in many cases.

bm_array_sample_100k__6k
	bm_array_sample_100k___10k
	bm_array_sample_100k___50k

This reverts commit r63463 / 14fb10a9ec41c77a91a778ca2f705c1897958afb

gc.c: use monotonic counters for objspace_malloc_increase

atomic_sub_nounderflow is expensive and objspace_malloc_increase
was showing up near the top of some `perf` profiles.  The new
implementation allows the compiler to inline and eliminate
some branches from objspace_malloc_increase.

Furthermore, we do not need atomics for oldmalloc_increase

This consistently improves bm_so_count_words benchmark by
around 10% on my hardware.

thread.c (rb_wait_for_single_fd): do not leak EINTR on timeout

We must not leak EINTR to users in case a signal hits a
ppoll/select caller right when (or just before) the timeout
expires.  In other words, the timeout should take precedence
over the -1 result from ppoll or select.

We also try one more time in case of EINTR with a zero timeout,
since technically the syscall finished before timing out if
it returns EINTR.

Regression appeared in r62457
("thread.c (update_timespec): use timespec_update_expire",
 commit e6bf0128add103730d8c96727f3ed4dab95088e4)

time to test this until preview2. So let me revert this and see how it

http_proxy setting should respect both parent domain and subdomain

URI::Generic: Respect no_proxy for both parent domain and
subdomains It is now possible to add just the subdomains for proxy bypass. In
a setting where the main domain needs to go through proxy while the
subdomains don't, it is now possible to just add the subdomains to the
no_proxy list.
The assumption that subdomains and the parent domain should
behave the same wrt no_proxy has been removed.

eg: Adding .example.com in no_proxy would allow example.com
to go through the proxy.

transform_mjit_header.rb: workaround for Solaris 10 with old GCC

* tool/transform_mjit_header.rb (MJITHeader.conflicting_types?):
  Add workaround for Solaris 10 with old GCC (4.6.2), that is
  essentially the same as for AIX (commit r62326), but probably
  due to different GCC versions, different error message is shown.

variable.c: fix multiple autoload with identical file (again)

We need to ensure autoload declarations pointing to the same
feature (aka "file") can wait on each other to avoid deadlock
situations.

So, reorganize autoload data structures to maintain a
feature => autoload_data_i mapping, and have module constant
tables point to the new autoload_const struct instead of
directly to autoload_data_i.  This allows multiple
autoload_const structs to refer to the SAME autoload_data_i
struct, and with it, the on-stack autoload_state.waitq.

The end result is different constants can share the same waitq
(tied to the feature name), and not deadlock each other during
loading.

Thanks to Eugene Kenny for the bug report and reproducible test case.

Prior to this commit, after arguments are pushed on 0010, stacks were:
VM stack: [uninitialized, uninitialized, len]
JIT stack: ["%0", len, len]

And then, when GC is invoked on 0016, VM stack will be [uninitialized, uninitialized]
and those uninitialized values will be marked by GC.

With this commit, after arguments are pushed on 0010, stacks will be:
VM stack: [len]
JIT stack: ["%0", len, len]

And VM stack will be [] on 0016.

optparse: Suppress warnings

Ruby warns "instance variable `@version` not initialized" for optparse when it receives `--version` option.

`test.rb`

```ruby
require 'optparse'
Version = '1'
OptionParser.new.parse(ARGV)
```

```
$ ruby -w test.rb --version
/home/pocke/.rbenv/versions/2.5.1/lib/ruby/2.5.0/optparse.rb:1168: warning: instance variable @version not initialized
/home/pocke/.rbenv/versions/2.5.1/lib/ruby/2.5.0/optparse.rb:1175: warning: instance variable @release not initialized
test 1
```

This change will suppress the warnings.

passing rb_thread_sleep to rb_protect is IMHO dangerous

rb_thread_sleep's argument is int, while rb_protect expects the function
to take VALUE. Depending on ABI this could be a problem.

We should wrap rb_thread_sleep here.

_mjit_compile_send.erb: retry inlining attr_reader

This reverts r63249 (revert r63212) and fixes a bug in it. The test to
prevent the bug is added as well.

vm_insnhelper.c: add `index` argument to vm_getivar. The argument is
created so that MJIT can pass the value of `cc->aux.index` on compilation
time.  The cache invalidation in _mjit_compile_send_guard.erb is only
working for the cache value on compilation time.
Note: As `index` is always passed as constant and it's force-inlined,
the performance of `vm_getivar` won't be degraded in VM.

_mjit_compile_send_guard.erb: New. Used to invalidate inlined values of cc.

LIST_HEAD as a local variable is a C99ism.

Address of a variable whose storage duration is `auto` is _not_ a
compile time constant, according to ISO 9899 section 6.4.
LIST_HEAD takes such thing.  You can't use it to declare local
variables.

Interestingly, address of a static variable _is_ a compile time
constant.  So a declaration like `static LIST_HEAD..` is
completely legal even in C90.

In C99 and newer, this is not a constraint violation.

rexml: disable XPath 1.0 compatible "#{ELEMENT_NAME}" processing by default

It breaks backward compatibility than I thought. So it's disabled by
default. It means that REXML's XPath processor isn't compatible with
XPath 1.0. But it will be acceptable for users.

We can enable it by specifying "strict: true" to
REXML::XPathParser.new explicitly.

* lib/rexml/xpath.rb,
  lib/rexml/xpath_parser.rb: Accept "strict: true" option.

Fix use of `rb_profile_frames` start parameter

rb_profile_frames was always behaving as if the value given for the
start parameter was 0.

The reason for this was that it would check if (start > 0) { then
continue without updating the control frame pointer or anything other
than decrementing start.

rexml: Fix XPath bug of /#{ELEMENT_NAME}

It doesn't mean that all elements which name "ELEMENT_NAME" with any
namespace URI including null namespace URI. It means that all elements
which name "ELEMENT_NAME" with null namespace URI.

https://www.w3.org/TR/1999/REC-xpath-19991116/#NT-NodeTest

> if the QName does not have a prefix, then the namespace URI is null
> (this is the same way attribute names are expanded).

We need to use "*[local-name()='#{ELEMENT_NAME}']" for all elements
which name "ELEMENT_NAME" with any namespace URI including null
namespace URI in XPath 1.0. But it's inconvenient. So this change
includes "*:#{LOCAL_NAME}" syntax support that is introduced since
XPath 2.0.

* lib/rexml/parsers/xpathparser.rb: Support "*:#{LOCAL_NAME}" syntax that
  is introduced since XPath 2.0.

* lib/rexml/xpath_parser.rb:
  * Fix namespace URI processing for "#{ELEMENT_NAME}". Now,
    "#{ELEMENT_NAME}" doesn't accept elements with null namespace URI.
  * Add "*:#{LOCAL_NAME}" support.

* test/rexml/test_contrib.rb,
  test/rexml/test_core.rb,
  test/rexml/xpath/test_base.rb: Follow this change.

* test/rexml/test_jaxen.rb: Fix namespace processing.

rb_queue/rb_szqueue/rb_condvar structs; store only a fork_gen
serial number to simplify management of these items.

This reduces initialization costs and avoids the up-front cost
of resetting all Queue/SizedQueue/ConditionVariable objects at
fork while saving 8 bytes per-structure on 64-bit.  There are no
savings on 32-bit.

simplify altstack and enable reuse with thread cache

Instead of allocating and registering the altstack in different
places, do it together to reduce code and improve readability.
When thread cache is enabled, storing altstack in rb_thread_t
is wasteful and we may reuse altstack in the same pthread.

This also lets us clearly allow use of xmalloc to allow GC to
recover from ENOMEM.

Add write barrier calls for direct marking objects.

This commit adds write barriers for objects marked from `rb_iseq_mark`.
r62851 introduced direct marking from iseqs to:

* keyword arg default values
* catch table iseqs
* VALUEs embedded in encoded instructions

This patch adds missing write barrier calls to those references.

mjit.c: add class serial of singleton class

for toplevel self.

Toplevel self's class is not `Object` but `#<Class:Object>`.
This commit allows to inline method call setup for toplevel methods.
I've thought r63053 works but it doesn't...

I actually want to add all singleton classes but I'm not sure what's the
good way for it. I assumed that using ObjectSpace.each_object is suboptimal.

Fix Fiber with Thread issue on Windows [Bug #14642]

* cont.c (rb_threadptr_root_fiber_setup): divide into two functions:
  * rb_threadptr_root_fiber_setup_by_parent(): called by the parent thread.
  * rb_threadptr_root_fiber_setup_by_child(): called by the created thread.

`rb_threadptr_root_fiber_setup()` is called by the parent thread and
  set fib->fib_handle by ConvertThreadToFiber() on the parent thread on
  Windows enveironment.
  This means that root_fib->fib_handle of child thread is initialized
  with parent thread's Fiber handle. Furthermore, second call of
  `ConvertThreadToFiber()` for the same thread fails.

This patch solves this weird situateion. However, maybe we can make more
  clean code.

webrick/httpproxy: stream request and response bodies

Reading entire request or response bodies into memory can lead
to trivial denial-of-service attacks.  Introduce Fibers in both
cases to allow streaming.

WEBrick::HTTPRequest gains a new body_reader method to prepare
itself as a source for IO.copy_stream.  This allows the
WEBrick::HTTPRequest object to be used as the
Net::HTTPGenericRequest#body_stream= arg for Net::HTTP.

For HTTP proxy response bodies, we also use a Fiber to
to make the HTTP request and read the response body.

WARNING! this will break apps completely which want to do
something with the body besides calculating the MD5 digest

We use the same 112 KB limit started (AFAIK) by Mongrel, Thin,

excessive ranges in multipart Range: requests.

Due to the way we rely on IO#gets and the desire to keep
the code simple, the actual maximum header may be 4093 bytes
larger than 112 KB, but we're splitting hairs at that point.

webrick/httpresponse: IO.copy_stream for regular files

Remove the redundant _send_file method since its functionality
is unnecessary with IO.copy_stream.  IO.copy_stream also allows
the use of sendfile under some OSes to speed up copies to
non-TLS sockets.

Testing with "curl >/dev/null" and "ruby -run -e httpd" to
read a 1G file over Linux loopback reveals a reduction from
around ~0.770 to ~0.490 seconds on the client side.

mjit.c: add timeout for --jit-wait

Sometimes test hangs in `mjit_get_iseq_func` like this:
http://ci.rvm.jp/results/trunk-test@ruby-sky3/659391

It seems that a process waiting in `mjit_get_iseq_func` does no longer
have MJIT worker thread. We don't wait for JIT finish forever. So I
added timeout for the case. I'm not sure why there was no MJIT worker
thread in ruby-sky3 test process though.

Unconditionally define `TRACE_INSN_P`

to look at decoded iseqs.  We have the decoded iseqs available, so no
reason to look at encoded ones.  This change allows us to clear
`original_iseq` from the iseq struct without any segvs (previously,
clearing `original_iseq` would cause the tests to crash).

Improve Pathname performance

If it will not use special variables (like $1, $&, $`...),
it can improve the performance by using Regexp#match? instead of Regexp#=~.
Because Regexp#=~ will generate the objects to special variables by pattern matching.

This patch will replace Regexp#=~ without special variables to Regexp#match?.

As you can see, it says `catch: FALSE`, but obviously it catches
exception raised from `return path`.

As of r62655, it was kind of intentional because I only cared about
expiration of JIT-ed frame and I've thought calling `vm_exec` is only
needed once for it. So r62654 was NOT actually checking if it may catch
exception.

But for r62678, obviously we should set catch_except_p=TRUE for all
ISeqs which may catch exception. Otherwise catch table lookup would
fail.

With this bugfix, code generated by r62655 might be worse, but at least
while loop can be marked as `catch: FALSE` as expected.

Add direct marking on iseq operands

Directly marking iseq operands allows us to eliminate the "mark array"
stored on ISEQ objects, which will reduce the amount of memory ISEQ
objects consume.  This patch changes the iseq mark function to:

* Directly marks ISEQ operands
* Iterate over and mark child ISEQs

It also introduces two flags on the ISEQ object.  In order to mark
instruction operands, we have to disassemble the instructions and find
the instruction parameters and types.  Instructions may also be
translated to jump addresses.  Instruction sequences may get marked by
the GC *while* they're mid flight (being compiled).  The
`ISEQ_TRANSLATED` flag is used to indicate whether or not the
instructions have been translated to jump addresses so that when we
decode the instructions we know whether or not we need to go from jump
location back to original instruction or not.

Not all ISEQ objects have any markable objects embedded in their
instructions.  We can detect whether or not an ISEQ has markable objects
in the instructions at compile time.  If the instructions contain
markable objects, we set a flag `ISEQ_MARKABLE_ISEQ` on the ISEQ object.
This means that during the mark phase, we can skip decompilation if the
flag is *not* set.  In other words, we can avoid decompilation of we
know in advance there is nothing to mark.

`once` instructions have an operand that contains the result of a
one-time compilation of a regex.  Before this patch, that operand was
called an "inline cache", even though the struct was actually an "inline
storage".  This patch changes the operand to be an "inline storage" so
that we can differentiate between caches that need marking (the inline
storage) and caches that don't need marking (inline cache).

mjit_compile.c: use local variables for stack

if catch_except_p is FALSE. If catch_except_p is TRUE, stack values
should be on VM's stack when exception is thrown and the JIT-ed frame
is re-executed by VM's exception handler. If it's FALSE, the JIT-ed
frame won't be re-executed and don't need to keep values on VM's stack.

Using local variables allows us to reduce cfp->sp motion. Moving cfp->sp
is needed only for insns whose handles_frame? is false. So it improves
performance.

_mjit_compile_insn.erb: Prepare `stack_size` variable for GET_SP,
STACK_ADDR_FROM_TOP, TOPN macros. Share pc and sp motion partial view.
Use cancel handler created in mjit_compile.c.

_mjit_compile_send.erb: ditto. Also, when iseq->body->catch_except_p is
TRUE, this stops to call mjit_exec directly. I described the reason in
vm_insnhelper.h's comment for EXEC_EC_CFP.

_mjit_compile_pc_and_sp.erb: Shared logic for moving sp and pc. As you
can see from thsi file, when status->local_stack_p is TRUE and
insn.handles_frame? is false, moving sp is skipped. But if
insn.handles_frame? is true, values should be rolled back to VM's stack.
common.mk: add dependency for the file

_mjit_compile_insn_body.erb: Set sp value before canceling JIT on
DISPATCH_ORIGINAL_INSN. Replace GET_SP, STACK_ADDR_FROM_TOP, TOPN macros
for the case ocal_stack_p is TRUE and insn.handles_frame? is false.
In that case, values are not available on VM's stack and those macros
should be replaced.

mjit_compile.inc.erb: updated comments of macros which are supported by
JIT compiler. All references to `cfp->sp` should be replaced and thus
INC_SP, SET_SV, PUSH are no longer supported for now, because they are
not used now.

vm_exec.h: moved EXEC_EC_CFP definition to vm_insnhelper.h because it's
tighly coupled to CALL_METHOD.

vm_insnhelper.h: Have revised EXEC_EC_CFP definition moved from vm_exec.h.
Now it triggers mjit_exec for VM, and has the guard for catch_except_p
on JIT-ed code. See comments for details. CALL_METHOD delegates
triggering mjit_exec to EXEC_EC_CFP.

insns.def: Stopped using EXEC_EC_CFP for the case we don't want to
trigger mjit_exec. Those insns (defineclass, opt_call_c_function) are
not supported by JIT and it's safe to use RESTORE_REGS(), NEXT_INSN().
expandarray is changed to pass GET_SP() to replace the macro in
_mjit_compile_insn_body.erb.

vm_insnhelper.c: change to take sp for the above reason.

erb.rb: relax warn level of ERB.new

I changed my mind and thought branching ERB.new in all libraries is too
hard. Code becomes too ugly. I increased the warn level to 2, and the
old initializer will be removed when Ruby 2.5 becomes EOL.
-S option of erb(1) stays in the same policy: will be removed at Ruby 2.7.

tool/generic_erb.rb: check ERB version

instead of Ruby's.

When older ERB is installed but Ruby is still 2.6.0, this may cause
error like:

```
Traceback (most recent call last):
    5: from ../src/tool/generic_erb.rb:36:in `<main>'
    4: from ../src/tool/generic_erb.rb:36:in `map'
    3: from ../src/tool/generic_erb.rb:43:in `block in <main>'

/opt/local/lib/ruby/2.6.0/erb.rb:869:in `block in result': no implicit conversion of Hash into Integer (TypeError)
```

For safety, I changed this to check ERB's version. See also: r62529.

version.c: show +JIT when --jit is passed

in version output.
version.h: ditto
ruby.c: propagate option for it
common.mk: updated dependency for version.c

mjit.c: overwrites the RUBY_DESCRIPTION to have +JIT when --jit is passed

test/ruby/test_rubyoptions.rb: add test for them

Only `ruby --jit -v` will have "+JIT", but this is intentional.
This may not be convenient for debugging by ticket with `ruby -v`,
but it's convenient for benchmark tools that pass options (--jit)
when showing it. At least such behavior is planned for benchmark_driver.gem
and this behavior is designed for it. Other benchmark tools are
recommended to follow the behavior too if they show version.
RUBY_DESCRIPTION might be useful for it too.

The position of "+JIT" is changed from original proposal because other
platforms like JRuby and TruffleRuby end it with archtecture.
It's made similar to JRuby, but it's upper-cased because Matz made approval
for "+JIT" in the ticket.

Example:
$ ruby -v
ruby 2.6.0dev (2018-02-22 trunk 62529) [x86_64-linux]
$ ruby --jit -v
ruby 2.6.0dev (2018-02-22 trunk 62529) +JIT [x86_64-linux]

After --jit is made default in the future, this output may be removed.
So do not rely on this output if possible.

thread_pthread.c: shorten and fix thread cache implementation

Update to use ccan/list for constant-time delete on expiry and
avoid malloc.  We must also initialize th->thread_id upon thread
reuse so Thread#name= works immediately upon thread creation.

We must also reinitialize the cache mutex and list_head on
fork like we do with GVL and timer thread mutexes.
While we're at it, use monotonic clock for timeout to avoid
system time changes.

"make exam TESTS='-x test_time_tz'" passes with USE_THREAD_CACHE
enabled (but remains off, here).

thread.c (thread_join_m): handle negative timeouts correctly

Users may subtract and round into negative values when using
Thread#join, so clamp the timeout to zero to avoid infinite/long
timeouts.

Note: other methods such as Kernel#sleep and IO.select will
raise on negative values, but Thread#join is an outlier *shrug*

This restores Ruby 2.5 (and earlier) behavior.

mjit_compile.inc.erb: replace opt_key insn

with opt_send_without_block insn if call cache has valid ISeq.
If the receiver is not optimized target of opt_key (i.e. Hash or Array),
it triggers JIT cancel and it would be slow.

This change allows JIT to drop the check for Hash/Array and continue to
execute JIT even if the receiver is not Hash or Array.

See the following benchmark results. It's not improved so much, but it
would be effective when we achieve Ruby method inlining in
_mjit_compile_send.erb.

* Micro benchmark

Given the following bench.rb,

```
class HashWithIndifferentAccess < Hash
  def []=(key, value)
    super(key.to_s, value)
  end

def [](key)
    super(key.to_s)
  end
end

indhash = HashWithIndifferentAccess.new
indhash[:foo] = 'bar'
key = 'foo'

100000000.times do
  indhash[key]
end
```

* optcarrot benchmark

Optcarrot has no room to be improved by this change. Almost nothing is changed.

* discourse benchmark

I expected this to be improved a little, but it isn't too.

st.c: retry operations if rebuilt

Calling the .eql? and .hash methods during a Hash operation can
result in a thread switch or a signal handler to run: allowing
one execution context to rebuild the hash table while another is
still reading or writing the table.  This results in a
use-after-free bug affecting the thread_safe-0.3.6 test suite
and likely other bugs.

This bug did not affect users of commonly keys (String, Symbol,
Fixnum) as those are optimized to avoid method dispatch
for .eql? and .hash methods.

A separate version of this change needs to be ported to Ruby 2.3.x
which had a different implementation of st.c but was affected
by the same bug.

* st.c: Add comment about table rebuilding during comparison.
  (DO_PTR_EQUAL_CHECK): New macro.
  (REBUILT_TABLE_ENTRY_IND, REBUILT_TABLE_BIN_IND): New macros.
  (find_entry, find_table_entry_ind, find_table_bin_ind): Use new
  macros.  Return the rebuild flag.
  (find_table_bin_ptr_and_reserve): Ditto.
  (st_lookup, st_get_key, st_insert, st_insert2): Retry the
  operation if the table was rebuilt.
  (st_general_delete, st_shift, st_update, st_general_foreach):
  Ditto.
  (st_rehash_linear, st_rehash_indexed): Use DO_PTR_EQUAL_CHECK.
  Return the rebuild flag.
  (st_rehash): Retry the operation if the table was rebuilt.
  [ruby-core:85510] [Ruby trunk Bug#14357]

Thanks to Vit Ondruch for reporting the bug.

transform_mjit_header.rb: ignore unsupported cc

to generate MJIT header.

Even if we can't build MJIT header, Ruby's build should success. And
compilers which are not explicitly supported are likely to fail to
transform MJIT header.

Also you can pass only gcc or clang to --jit-cc=xxx for now. Thus
generating header does never make sense.

So I decided to conservatively give up MJIT header generation.
But please feel free to add your favorite compiler's macro if you think
it's working. (Another workaround is passing -D__GNUC__ :p)

thread.c: favor timespec internally

This results in fewer conversion on common modern systems with
support for clock_gettime, pthread_cond_timedwait and ppoll.
gettimeofday is declared obsolete by POSIX.1-2008, so it is yet
another reason to move away from it.  This also appears to result
in the reduction of compatibility code required for dealing
with inconsistent implementations of "struct timeval".tv_sec

In the future, this will also result in fewer conversions for
kqueue and pselect if we elect to use them.

ruby_init_prelude() (L1681). So the place of mjit_init() is moved.

Makefile.in: Removed static prefix from MJIT_HEADER_ISNTALL_DIR macro.
And this removes the unused LIBRUBY_LIBDIR macro as well.
win32/Makefile.sub: ditto.

Another try of r62204 and r62192.

As far as I can see from solaris's signal.h and sys/procset.h, the only
possibility that causes the following error would be that sys/procset.h
is included without __EXTENSIONS__ and signal.h included it again but it
doesn't define procset_t.  Let's define __EXTENSIONS__ from first.

Reverted r62192 and added another try.
I prepared Solaris environment but I couldn't reproduce the RubyCI build

I found the following article and it fixed the same problem with passing
`-D__EXTENSIONS__`. So this commit defines `__EXTENSIONS__` for Solaris.

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.
proc.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.

 to fix it. Please wait for the fix.)

mjit.c: use InterlockedExchangePointer

for Windows, if it's available.

Before this commit, Windows builds printed following warnings.
mjit.c
../mjit.c(802) : warning C4047: 'function' : 'volatile LONG *' differs in levels of indirection from 'void **'
../mjit.c(802) : warning C4024: '_InterlockedExchange' : different types for formal and actual parameter 1
../mjit.c(802) : warning C4047: 'function' : 'LONG' differs in levels of indirection from 'void *'
../mjit.c(802) : warning C4024: '_InterlockedExchange' : different types for formal and actual parameter 2

ATOMIC_SET is using InterlockedExchange which takes LONG as its value.
As InterlockedExchangePointer takes PVOID, we should use this to set
function pointer atomically.

mjit.c: merge MJIT infrastructure

that allows to JIT-compile Ruby methods by generating C code and
using C compiler.  See the first comment of mjit.c to know what this
file does.

mjit.c is authored by Vladimir Makarov <vmakarov@redhat.com>.
After he invented great method JIT infrastructure for MRI as MJIT,
Lars Kanis <lars@greiz-reinsdorf.de> sent the patch to support MinGW
in MJIT. In addition to merging it, I ported pthread to Windows native
threads. Now this MJIT infrastructure can be compiled on Visual Studio.

This commit simplifies mjit.c to decrease code at initial merge. For
example, this commit does not provide multiple JIT threads support.
We can resurrect them later if we really want them, but I wanted to minimize
diff to make it easier to review this patch.

`/tmp/_mjitXXX` file is renamed to `/tmp/_ruby_mjitXXX` because non-Ruby
developers may not know the name "mjit" and the file name should make
sure it's from Ruby and not from some harmful programs.  TODO: it may be
better to store this to some temporary directory which Ruby is already using
by Tempfile, if it's not bad for performance.

mjit.h: New. It has `mjit_exec` interface similar to `vm_exec`, which is
for triggering MJIT. This drops interface for AOT compared to the original
MJIT.

Makefile.in: define macros to let MJIT know the path of MJIT header.
Probably we can refactor this to reduce the number of macros (TODO).
win32/Makefile.sub: ditto.

common.mk: compile mjit.o and mjit_compile.o. Unlike original MJIT, this
commit separates MJIT infrastructure and JIT compiler code as independent
object files. As initial patch is NOT going to have ultra-fast JIT compiler,
it's likely to replace JIT compiler, e.g. original MJIT's compiler or some
future JIT impelementations which are not public now.

inits.c: define MJIT module. This is added because `MJIT.enabled?` was
necessary for testing.
test/lib/zombie_hunter.rb: skip if `MJIT.enabled?`. Obviously this
wouldn't work with current code when JIT is enabled.
test/ruby/test_io.rb: skip this too. This would make no sense with MJIT.

ruby.c: define MJIT CLI options. As major difference from original MJIT,
"-j:l"/"--jit:llvm" are renamed to "--jit-cc" because I want to support
not only gcc/clang but also cl.exe (Visual Studio) in the future. But it
takes only "--jit-cc=gcc", "--jit-cc=clang" for now. And only long "--jit"
options are allowed since some Ruby committers preferred it at Ruby
developers Meeting on January, and some of options are renamed.
This file also triggers to initialize MJIT thread and variables.
eval.c: finalize MJIT worker thread and variables.
test/ruby/test_rubyoptions.rb: fix number of CLI options for --jit.

thread_pthread.c: change for pthread abstraction in MJIT. Prefix rb_ for
functions which are used by other files.
thread_win32.c: ditto, for Windows.  Those pthread porting is one of major
works that YARV-MJIT created, which is my fork of MJIT, in Feature 14235.
thread.c: follow rb_ prefix changes

vm.c: trigger MJIT call on VM invocation. Also trigger `mjit_mark` to avoid
SEGV by race between JIT and GC of ISeq. The improvement was provided by
wanabe <s.wanabe@gmail.com>.
In JIT compiler I created and am going to add in my next commit, I found
that having `mjit_exec` after `vm_loop_start:` is harmful because the
JIT-ed function doesn't proceed other ISeqs on RESTORE_REGS of leave insn.
Executing non-FINISH frame is unexpected for my JIT compiler and
`exception_handler` triggers executions of such ISeqs. So `mjit_exec`
here should be executed only when it directly comes from `vm_exec` call.
`RubyVM::MJIT` module and `.enabled?` method is added so that we can skip
some tests which don't expect JIT threads or compiler file descriptors.

vm_insnhelper.h: trigger MJIT on method calls during VM execution.

vm_core.h: add fields required for mjit.c. `bp` must be `cfp[6]` because
rb_control_frame_struct is likely to be casted to another struct. The
last position is the safest place to add the new field.
vm_insnhelper.c: save initial value of cfp->ep as cfp->bp. This is an
optimization which are done in both MJIT and YARV-MJIT. So this change
is added in this commit. Calculating bp from ep is a little heavy work,
so bp is kind of cache for it.

iseq.c: notify ISeq GC to MJIT. We should know which iseq in MJIT queue
is GCed to avoid SEGV.  TODO: unload some GCed units in some safe way.

gc.c: add hooks so that MJIT can wait GC, and vice versa. Simultaneous
JIT and GC executions may cause SEGV and so we should synchronize them.

cont.c: save continuation information in MJIT worker. As MJIT shouldn't
unload JIT-ed code which is being used, MJIT wants to know full list of
saved execution contexts for continuation and detect ISeqs in use.

mjit_compile.c: added empty JIT compiler so that you can reuse this commit
to build your own JIT compiler. This commit tries to compile ISeqs but
all of them are considered as not supported in this commit. So you can't
use JIT compiler in this commit yet while we added --jit option now.

common.mk: install a single header file for JIT

compilation which is created by transforming a preprocessed vm.c.
This file will be used by JIT compiler's generated code which we are
going to have from succeeding commits.

Makefile.in: generate MJIT header for UNIX environments.
win32/Makefile.sub: generate MJIT header for mswin environments.
At initial merge, we're going to support only MinGW for Windows. So the
header installed by this file won't be used for short term, but we'll
add mswin support in a half year or so, for sure.

tool/transform_mjit_header.rb: New. This script was originally written as
minimize_mjit_header.rb by Vladimir N. Makarov <vmakarov@redhat.com> for
Feature 12589.
Then I refactored a little so that it can conform CodeClimate CI which is
currently set for Ruby's GitHub repository, and fixed some bugs and ported
it to work on Windows.

Also, as original minimize_mjit_header.rb takes too long time to run,
this is modified to skip minimization step because having *static*
unused definitions does not waste compilation time on -O2 since compiler
can skip to compile unused static functions. So this does no longer
"minimize" the header and is renamed.

This header installation does NOT include a header to automatically
export symbols used by MJIT. That's because original MJIT code was
failing to export symbols in the import header in macOS environment.
But I would like to have the functionality for maintainability in the
future. I'll manually export things but it would be just an intemediate
solution.

ia64: update ia64-specific code to use execution context

This change follows commit 837fd5e494731d7d44786f29e7d6e8c27029806f
in '#ifdef __ia64' branches.

Noticed as a build failure by John Paul Adrian Glaubitz:

```
  cont.c:502:50: error: 'rb_thread_t {aka struct rb_thread_struct}'
    has no member named 'machine'
       size = cont->machine.register_stack_size =
           th->machine.register_stack_end - th->machine.register_stack_start;
               ^~
```

The change is trivial: update 'th->machine' usage to 'th->ec->machine'.

eliminate CALL_SIMPLE_METHOD

Arrange operands of several opt_something insns so that jumps to
opt_send_without_block can be applied to them. This makes it
possible to eliminate CALL_SIMPLE_METHOD macro at all.  Results
in binary size of vm_exec_core to change from 27,008 bytes to
26,016 bytes on my machine. [close GH-1779]

Note however that PC can point somewhere non-instruction now.

s/CALL_SIMPLE_METHOD/DISPATCH_ORIGINAL_INSN/

Now that DISPATCH_ORIGINAL_INSN is introduced, we can replace
CALL_SIMPLE_METHOD with DISPATCH_ORIGINAL_INSN. These two macros
differ in size very much and results in this big difference in
compiled binary size. This changeset reduces the size of
vm_exec_core from 32,352 bytes to 27,008 bytes on my machine.  As
a result it yields slightly better performance.
Closes [GH-1779].

also use sp_inc in vm core

Now that sp_inc attributes are officially provided as inline
functions. Why not use them directly from the vm core, not just
by the compiler. By doing so, it is now possible for us to
optimize stack manipulations. We can now know exactly how many
words of stack space an instruction consumes before it actually
does. This changeset deletes some lines from insns.def because
they are no longer needed.  As a result it reduces the size of
vm_exec_core function from 32,400 bytes to 32,352 bytes on my
machine.

It seems it does not affect performance:

treat PC for gc events

ADD_PCs moved. That didn't change vast majority of event hooks
because vm_traece() has been placed before ADD_PC. However for GC
events the situation is different. We have to take care.

move ADD_PC around to optimize PC manipluiations

This commit introduces new attribute handles_flame and if that is
_not_ the case, places ADD_PC right after INC_SP.  This improves
locality of PC manipulations to prevents unnecessary register spill-
outs. As a result, it reduces the size of vm_exec_core from 32,688
bytes to 32,384 bytes on my machine.

Speedup is very faint, but certain.

ruby/ruby.h: remove unnecessary exports from C-API

Needlessly exporting can reduce performance locally and increase
binary size.

Increasing the footprint of our C-API larger is also detrimental
to our development as it encourages tighter coupling with our
internals; making it harder for us to preserve compatibility.

If some parts of the core codebase needs access to globals,
internal.h should be used instead of anything in include/ruby/*.

ext/ripper/tools/dsl.rb: Serialize dispatch calls

To avoid the unspecified behavior (the evaluation order of arguments).
In `$$ = foo(bar(), baz());`, it is unspecified which `bar` or `baz` is
called earlier.

This commit changes the code to `v1=bar(); v2=baz(); $$ = foo();`.

parse.y: rewrite excessed_comma process

Currently, parser.y includes core parser and Ripper parser obscurity.
In addition, *some* Ripper code uses the result of the core parser,
which make it difficult to separate the two parsers.

I want to simplify this, not by separating the two parsers, but by
making *all* Ripper actions follows the core parser actions.
In other words, all the core parser actions run always even in Ripper,
and after that, Ripper-specific actions run.

For tha sake, in principle, I want to put `/*% ripper: ... %*/` in the
end of actions.
Anyway, it is too dirty to put it within expressions, IMO.

parse.y: Remove unneeded var_field_1 trick

I thought this trick was needed because the result of var_field was
passed to different arguments, as follows:

```
$1 = var_field(p, $1);
$$ = backref_assign_error(p, $1, $1, &@$);
```

Currently the DSL supports that one result is passed to one argument.

However, after the refactoring, I found that `backref_assign_error`
uses only one `$1`.

ext/ripper: Introduce a simple DSL for ripper.y code generation

Currently, parse.y actions are hard to read and write because the code
has double meaning (for core parser and for ripper).  I think that, if
it is easy to write ripper's code shortly and simply, the double meaning
trick is not needed.

For the sake, this change adds a simple DSL for ripper's code.  For
example, in parse.y, we can write:

/*% ripper: stmts_add(stmts_new, void_stmt) %*/

instead of:

$$ = dispatch2(stmts_add, dispatch0(stmts_new),
                   dispatch0(void_stmt));

__attibute__((__aligned__)) for RSTRING_PTR()

For instance array.c:rb_ary_product() uses RSTRING_PTR() as an
array of int. So to avoid misaligned memory access RSTRING_PTR()
must at least be sizeof(int)-aligned.  However the type of
RSTRING_PTR() is char*, which of course can expect alignment as
much as 1.  This is a problem.

The reality is, there is no misaligned memory access because the
memory region behind RSTRING_PTR() is allocated using malloc().
Memory regions returned from malloc() are always aligned
appropriately.  So let's tell the compiler about this information.
It seems GCC, clang, and MSVC have such feature.

parse.y: Remove almost all *_gen macros by passing parser_params explicitly

In parse.y many functions were suffixed "_gen" and had companion macros
to pass struct parser_params implicitly, which made parse.c bigger and
more obscure.

This change expands and removes almost all "*_gen" macros.  This
requires explicit passing of struct parser_params, i.e., we need to
write "foo(p, ..)" instead of "foo(..)".  However, it is just extra
three letters.  I believe that this is easier to understand.

delete tool/instruction.rb (2nd try)

Previous commit changed insns.def format. Now is the time for its
generators. In doing so I chose to modernize the system, not just
patch.  My attempt includes

- extensive use of Onigumo regular expressions
- split from one big file (instruction.rb) into separated MVC
- partial view

Also, let me take this opportunity to kill old unused features
such as

- stack caching
- minsns / yasmdata which are never seriously used
- yarvarch document generation (moved to doc/)
- vast majority of unused arguments to insns2vm.rb

This commit generates VM source codes that cleanly compile, and
the generated binary passes tests.  At least for me.

instead of Errno::ECONNREFUSED.

As I commented in r61498, at that moment I was not sure if the actual
exception is really `Errno::ECONNREFUSED` or not.

In https://ci.appveyor.com/project/ruby/ruby/build/1.0.6974, I could
confirm that the download can fail with `Errno::ETIMEDOUT`. So I want to
retry that.

Let's add `Errno::ECONNREFUSED` too if it fails with the exception.

It had used `id -un`, but it is not always equal to `Etc.getlogin`.
`id` returns the current user of the process, and `Etc.getlogin` returns
the user name logged in on the controlling terminal of the process.

This change uses `logname` by default.  `id` remains as a fallback since
there seem to be some platforms where `logname` is not available:

Some tests had failed on `sudo make test-all`, mainly because root can

guards into such tests.

Note that almost all tests in which `skip` guards is added, already have
"windows" guard.  This is because there is no support to avoid read

delete tool/instruction.rb

Previous commit changed insns.def format. Now is the time for its
generators. In doing so I chose to modernize the system, not just
patch.  My attempt includes

- extensive use of Onigumo regular expressions
- split from one big file (instruction.rb) into separated MVC
- partial view

Also, let me take this opportunity to kill old unused features
such as

- stack caching
- minsns / yasmdata which are never seriously used
- yarvarch document generation (moved to doc/)
- vast majority of unused arguments to insns2vm.rb

This commit generates VM source codes that cleanly compile, and
the generated binary passes tests.  At least for me.

Because the name "code_range" is ambiguous with encoding's.
Abbreviations ("crange", and "cr") are also renamed to "loc".

The traditional "code_location" (a pair of lineno and column) is
renamed to "code_position".  Abbreviations are also renamed
(first_loc to beg_pos, and last_loc to end_pos).

A location (abbr. loc) is a point in a program and consists of line
number and column number.  A code range (abbr. crange and cr) is a range
within a program and consists of a pair of locations which is the first

parse.y: set bison's first_loc.lineno to nd_line by default

This change initializes nd_line, lineno of each node, by default, by
using the first line number of code range that bison tracks, instead of
extracting from lexer state.
The lexer state basically provides only the last line number of code
range, so many hacks are used to approximate the first line number.  The
hacks have been introduced on demand, or very ad-hocly.  I think this
change will make it possible to remove most of the hacks.

zlib: reduce garbage on Zlib::GzipReader#readpartial

For garbage-concious users who use the `outbuf' argument of
`readpartial' to supply a destination buffer, this provides
a drastic reduction in garbage when inflating large inputs
in a streaming fashion.

This results in a anonymous RSS reduction in the reader
similar to the reduction in the writer from r61631.

There's no need to allocate a temporary string when @rbuf is

pre-existing data in the read buffer.

zlib: reduce garbage on gzip writes (deflate)

Zlib::GzipWriter generated large amounts of garbage from
(struct zstream).input.  Reuse the .input field when it is
hidden, and recycle it when its lifetime is over.  This change
alone reduced memory usage of the writer from 90MB to 4.5MB.

For the detached buffer of compressed data used by
gzfile_write_raw, we can only clear the string (not recycle it)
since user code may hold references to it (but the data would be
clobbered, anyways).  This reduced memory usage slightly by
around 0.5MB (because it's smaller compressed data).

Combined, these changes reduce the anonymous RSS memory of a
dedicated writer process from over 90MB to under 4MB.

Denying write permissions to the owner seems wrong.

changes.

node.h: remove NODE_PRELUDE

NODE_PRELUDE contains a `BEGIN` node, a main node, and compile_option.
This node is assumed that it must be located immediately under the root
NODE_SCOPE, but this strange assumption is not so good, IMO.

This change removes the assumtion; it integrates the former two nodes by
block_append, and moves compile_option into rb_ast_body_t.

net/protocol: optimize large read case

There are several places where rbuf_consume is called with
@rbuf.size as its length arg; simplify that case by avoiding
the slow String#slice! operation in favor of a lightweight
replacement.

The following script exhibits reduced memory usage and
runtimes using the time(1) command:

2.9s =>  2.6s
	70MB => 12 MB

---------
require 'net/http'
require 'digest/md5'
Thread.abort_on_exception = true
s = TCPServer.new('127.0.0.1', 0)
len = 1024 * 1024 * 1024
th = Thread.new do
  c = s.accept
  c.readpartial(16384)
  c.write("HTTP/1.0 200 OK\r\nContent-Length: #{len}\r\n\r\n")
  IO.copy_stream('/dev/zero', c, len)
  c.close
end

addr = s.addr
Net::HTTP.start(addr[3], addr[1]) do |http|
  http.request_get('/') do |res|
    dig = Digest::MD5.new
    res.read_body { |buf|
      dig.update(buf)
      # String#clear is important to reduce malloc overhead,
      # but most Ruby programmers don't do this :<
      buf.clear

offsetof(type, foo.bar) is (arguably) a GCCism

TL;DR see http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2031.htm

Suppose we have:

struct X {
  struct Y {
    z_t z;
  } y;
} x;

then, you _cant_ infer offsetof(struct X, y.z). The ISO C99 section
7.17 says nothing about such situation. At least clang warns this
being an extension to the language (-Wextended-offsetof).

initializer paren-string `{("str")}` is a C99ism

First, `"str"` is a string constant but `("str")` is not.  It is a
random expression whose type happen to be const char*.  Second,
non-constant initializer element is forbidden in C90.  Mixture of
these two results in the fact that `{("str")}` is a C99ism.

Just delete the parens and everything goes well.

explicit cast to void* required for %p

promotion is expected.  You have to do it by hand.

suppress warning for clang

In this function, "volatile" is specified twice in macro-expanded
`VAR_INITIALIZED(cont)` part.  That is a problem in fact.  However
I don't want to touch this line because it is already a messy
workaround for clang SEGV.  Let me just ignore.
