If there's a syntax error during iseq compilation then prism would leak
memory because it would not free the pm_parse_result_t.
This commit changes pm_iseq_new_with_opt to have a rb_protect to catch
when an error is raised, and return NULL and set error_state to a value
that can be raised by calling rb_jump_tag after memory has been freed.
For example:
10.times do
10_000.times do
eval("/[/=~s")
rescue SyntaxError
end
puts `ps -o rss= -p #{$$}`
end

to show unused block warning strictly.
```ruby
class C
def f = nil
end
class D
def f = yield
end
[C.new, D.new].each{|obj| obj.f{}}
```
In this case, `D#f` accepts a block. However `C#f` doesn't
accept a block. There are some cases passing a block with
`obj.f{}` where `obj` is `C` or `D`. To avoid warnings on
such cases, "unused block warning" will be warned only if
there is not same name which accepts a block.
On the above example, `C.new.f{}` doesn't show any warnings
because there is a same name `D#f` which accepts a block.
We call this default behavior as "relax mode".
`strict_unused_block` new warning category changes from
"relax mode" to "strict mode", we don't check same name
methods and `C.new.f{}` will be warned.

Since the prism parser was enabled by default, loading scripts with nonascii characters somewhere in the script path is no longer working.
It only works when the codepage was switched to 65001 (UTF-8).
This patch doesn't change the encoding of __FILE__. It is still in locale encoding.
That's why pm_load_file() is called with UTF-8 script name and pm_parse_file() with locale encoding.
The loading of nonascii script names is part of the test-all, but it doesn't trigger the failure on GHA, since it is using cp 65001.
On other codepages it fails with:
[53/71] TestRubyOptions#test_command_line_progname_nonascii = 0.04 s

This way there is one place to change for switching the default.
This also allows for building the same commit with different cppflags.

`--disable-frozen-string-literal`
[Feature #20205]
This was an undesired side effect. Now that this value is a triplet, we can't
assume it's disabled by default.

This commit changes the external GC to be loaded with the `--gc-library`
command line argument instead of the RUBY_GC_LIBRARY_PATH environment
variable because @nobu pointed out that loading binaries using environment
variables can pose a security risk.

If you start Ruby with `--yjit-disable`, the `+YJIT` shouldn't be
added until `RubyVM::YJIT.enable` is actually called. Otherwise
it's confusing in crash reports etc.

This patch removes the `VALUE flags` member from the `rb_ast_t` structure making `rb_ast_t` no longer an IMEMO object.
## Background
We are trying to make the Ruby parser generated from parse.y a universal parser that can be used by other implementations such as mruby.
To achieve this, it is necessary to exclude VALUE and IMEMO from parse.y, AST, and NODE.
## Summary (file by file)
- `rubyparser.h`
- Remove the `VALUE flags` member from `rb_ast_t`
- `ruby_parser.c` and `internal/ruby_parser.h`
- Use TypedData_Make_Struct VALUE which wraps `rb_ast_t` `in ast_alloc()` so that GC can manage it
- You can retrieve `rb_ast_t` from the VALUE by `rb_ruby_ast_data_get()`
- Change the return type of `rb_parser_compile_XXXX()` functions from `rb_ast_t *` to `VALUE`
- rb_ruby_ast_new() which internally `calls ast_alloc()` is to create VALUE vast outside ruby_parser.c
- `iseq.c` and `vm_core.h`
- Amend the first parameter of `rb_iseq_new_XXXX()` functions from `rb_ast_body_t *` to `VALUE`
- This keeps the VALUE of AST on the machine stack to prevent being removed by GC
- `ast.c`
- Almost all change is replacement `rb_ast_t *ast` with `VALUE vast` (sorry for the big diff)
- Fix `node_memsize()`
- Now it includes `rb_ast_local_table_link`, `tokens` and script_lines
- `compile.c`, `load.c`, `node.c`, `parse.y`, `proc.c`, `ruby.c`, `template/prelude.c.tmpl`, `vm.c` and `vm_eval.c`
- Follow-up due to the above changes
- `imemo.{c|h}`
- If an object with `imemo_ast` appears, considers it a bug

Previously it would bypass the `FL_ABLE` check, but
since shapes introduction, it started having a different
behavior than `OBJ_FREEZE`, as it would onyl set the `FL_FREEZE`
flag, but not update the shape.
I have no indication of this causing a bug yet, but it seems
like a trap waiting to happen.

This patch is part of universal parser work.
## Summary
- Decouple VALUE from members below:
- `(struct parser_params *)->debug_lines`
- `(rb_ast_t *)->body.script_lines`
- Instead, they are now `rb_parser_ary_t *`
- They can also be a `(VALUE)FIXNUM` as before to hold line count
- `ISEQ_BODY(iseq)->variable.script_lines` remains VALUE
- In order to do this,
- Add `VALUE script_lines` param to `rb_iseq_new_with_opt()`
- Introduce `rb_parser_build_script_lines_from()` to convert `rb_parser_ary_t *` into `VALUE`
## Other details
- Extend `rb_parser_ary_t *`. It previously could only store `rb_parser_ast_token *`, now can store script_lines, too
- Change tactics of building the top-level `SCRIPT_LINES__` in `yycompile0()`
- Before: While parsing, each line of the script is added to `SCRIPT_LINES__[path]`
- After: After `yyparse(p)`, `SCRIPT_LINES__[path]` will be built from `p->debug_lines`
- Remove the second parameter of `rb_parser_set_script_lines()` to make it simple
- Introduce `script_lines_free()` to be called from `rb_ast_free()` because the GC no longer takes care of the script_lines
- Introduce `rb_parser_string_deep_copy()` in parse.y to maintain script_lines when `rb_ruby_parser_free()` called
- With regard to this, please see *Future tasks* below
## Future tasks
- Decouple IMEMO from `rb_ast_t *`
- This lifts the five-members-restriction of Ruby object,
- So we will be able to move the ownership of the `lex.string_buffer` from parser to AST
- Then we remove `rb_parser_string_deep_copy()` to make the whole thing simple

Additional flags are comma separated list preceeded by `-` or `+`.
Before:
```sh
$ ruby --dump=insns+without_opt
```
After:
```sh
$ ruby --dump=insns-opt,-optimize
```
At the same time, `parsetree_with_comment` is split to `parsetree`
option and additional `comment` flag.
Before:
```sh
$ ruby --dump=parsetree_with_comment
```
After:
```sh
$ ruby --dump=parsetree,+comment
```
Also flags can be separate `--dump`.
```sh
$ ruby --dump=parsetree --dump=+comment --dump=+error_tolerant
```
Ineffective flags are ignored silently.
```sh
$ ruby --dump=parsetree --dump=+comment --dump=+error_tolerant
```
|
|
Restructure `insns_without_opt` and `parsetree_with_comment` as
`insns+without_opt` and `parsetree+with_comment` respectively, like
`+error-tolerant`.

This patch suggests relocating the code dealing with `SCRIPT_LINES__` from ast.c to ruby_parser.c.
## Background
- I guess `AbstractSyntaxTree.of` method used to use `SCRIPT_LINES__` internally for some reason before
- However, now it appears `SCRIPT_LINES__` is no longer used meaningfully by the method
- As evidence of this, (and as my patch shows,) removing the function call of `rb_script_lines_for()` from `ast_s_of()` does not affect the result of `test/ruby/test_ast.rb`
Given the above, I think two possibilities can be considered:
- (A) `AbstractSyntaxTree.of` has not needed `SCRIPT_LINES__` already (I pick this)
- (B) We lack a test case of `AbstractSyntaxTree.of` that needs to use `SCRIPT_LINES__`
## Besides,
The current implementation causes strange behavior:
```console
ruby -e"SCRIPT_LINES__ = {__FILE__ => []}; puts RubyVM::AbstractSyntaxTree.of(->{ 1 + 2 }, keep_script_lines: true).script_lines"
=> `-e:1:in '<main>': undefined method 'script_lines' for nil (NoMethodError)`
```
I think this is a bug because `AbstractSyntaxTree.of` is not supposed to return `nil` even in this case.
This happens due to the ast.c's dependence on `SCRIPT_LINES__`.
And at the end of the `ast_s_of()`, `node_find()` can not find the target child node obviously because it doesn't make sense to look for a corresponding node made from the parameter of `AbstractSyntaxTree.of` in the AST tree made from the value of `{__FILE__ => []}`
## Solution
Since I think it's good enough `SCRIPT_LINES__` to be only referred by ruby.c, I chose the possibility "(A)" and wrote this patch which moves `rb_script_lines_for()` from ast.c to ruby_parser.c.
So as the result:
- `ast_s_of()` function no longer look up `SCRIPT_LINES__`
- Even so, this patched code passes the existing tests
- The strange behavior above no longer happens (I also added a test for it)
Please correct me if I miss something🙏

[Feature #20205]
As a path toward enabling frozen string literals by default in the future,
this commit introduce "chilled strings". From a user perspective chilled
strings pretend to be frozen, but on the first attempt to mutate them,
they lose their frozen status and emit a warning rather than to raise a
`FrozenError`.
Implementation wise, `rb_compile_option_struct.frozen_string_literal` is
no longer a boolean but a tri-state of `enabled/disabled/unset`.
When code is compiled with frozen string literals neither explictly enabled
or disabled, string literals are compiled with a new `putchilledstring`
instruction. This instruction is identical to `putstring` except it marks
the String with the `STR_CHILLED (FL_USER3)` and `FL_FREEZE` flags.
Chilled strings have the `FL_FREEZE` flag as to minimize the need to check
for chilled strings across the codebase, and to improve compatibility with
C extensions.
Notes:
- `String#freeze`: clears the chilled flag.
- `String#-@`: acts as if the string was mutable.
- `String#+@`: acts as if the string was mutable.
- `String#clone`: copies the chilled flag.

In preparation for https://bugs.ruby-lang.org/issues/20205.
The `frozen_string_literal` compilation option will no longer
be a boolean but a tri-state: `on/off/default`.

The following parts will not be shown for `-h` option. And not to
reach 80 columns. Some terminal emulators (Windows command prompt at
least) wrap the cursor to the next line when reaching the rightmost
column, before exceeding.

Since it did not make sense without `--parser=prism` option, just a
duplication. Now it is `--parser=prism --dump=parsetree`.

This fixes some inconsistencies introduced by that PR.

This `st_table` is used to both mark and pin classes
defined from the C API. But `vm->mark_object_ary` already
does both much more efficiently.
Currently a Ruby process starts with 252 rooted classes,
which uses `7224B` in an `st_table` or `2016B` in an `RArray`.
So a baseline of 5kB saved, but since `mark_object_ary` is
preallocated with `1024` slots but only use `405` of them,
it's a net `7kB` save.
`vm->mark_object_ary` is also being refactored.
Prior to this changes, `mark_object_ary` was a regular `RArray`, but
since this allows for references to be moved, it was marked a second
time from `rb_vm_mark()` to pin these objects.
This has the detrimental effect of marking these references on every
minors even though it's a mostly append only list.
But using a custom TypedData we can save from having to mark
all the references on minor GC runs.
Addtionally, immediate values are now ignored and not appended
to `vm->mark_object_ary` as it's just wasted space.
