Follow up for 5e16857315. Calling a method
in the middle of const_set adds a way that it would fail. It also makes
it inconsistent with declaring a constant using `::`, which doesn't call
`to_s`.
Former ROBJECT_IV_INDEX_TBL macro included RCLASS_IV_INDEX_TBL, which is
not disclosed to extension libraies. The macro was kind of broken. Why
not just deprecate it, and convert the internal use into an inline
function.
Use ID instead of GENTRY for gvars.
Global variables are compiled into GENTRY (a pointer to struct
rb_global_entry). This patch replace this GENTRY to ID and
make the code simple.
We need to search GENTRY from ID every time (st_lookup), so
additional overhead will be introduced.
However, the performance of accessing global variables is not
important now a day and this simplicity helps Ractor development.
Not every compilers understand that rb_raise does not return. When a
function does not end with a return statement, such compilers can issue
warnings. We would better tell them about reachabilities.
900e83b501 changed from a warning
to an error in this case, but the warning was only issued in
verbose mode, and therefore the error was only raised in verbose
mode. That was not intentional, verbose mode should only change
whether warnings are emitted, not other behavior. This issues
the RuntimeError in all cases.
This change broke a couple tests, as the tests actually issued
the warning and therefore now raise an error. This wasn't caught
earlier as test_variable suppressed the warning in this case,
effectively setting $VERBOSE = false around the code that warned.
basictest isn't run in verbose mode and therefore didn't expose
the issue previously. Fix these tests.

Setting class varibles goes through the ancestor list which can
contain iclasses. Iclasses share a lot of information with the
module they are made from, but not the frozen status.
Check the frozen status of the module instead of the iclass.
This patch allows global variables that have been assigned in Ruby to
move. I added a new function for the GC to call that will update
global references and introduced a new callback in the global variable
struct for updating references.
Only pure Ruby global variables are supported right now, other
references will be pinned.
This changes the following warnings:
* warning: class variable access from toplevel
* warning: class variable @foo of D is overtaken by C
into RuntimeErrors. Handle defined?(@@foo) at toplevel
by returning nil instead of raising an exception (the previous
behavior warned before returning nil when defined? was used).
Refactor the specs to avoid the warnings even in older versions.
The specs were checking for the warnings, but the purpose of
the related specs as evidenced from their description is to
test for behavior, not for warnings.

Since 9d9aea7fe5, generic instance
variables need `iv_index_tbl` in the object's class. As hidden
objects, however, have no class, access to the variables causes a
segfault. Get rid of that segfault by raising an exception, for
the time being.
I think global references should either be 0 or valid heap pointers.
`rb_gc_mark_maybe` checks to see if the pointer is a valid heap pointer,
but I believe we already know they are valid addresses
If the instance variable table hasn't been "expanded", allocate the
maximum size of the ivar table. This operates under the assumption that
most objects will eventually expand their ivar array to the maximum
width anyway, so we may as well avoid realloc calls.
Saves comitters' daily life by avoid #include-ing everything from
internal.h to make each file do so instead. This would significantly
speed up incremental builds.
We take the following inclusion order in this changeset:
1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very
first thing among everything).
2. RUBY_EXTCONF_H if any.
3. Standard C headers, sorted alphabetically.
4. Other system headers, maybe guarded by #ifdef
5. Everything else, sorted alphabetically.
Exceptions are those win32-related headers, which tend not be self-
containing (headers have inclusion order dependencies).
This copies the private/deprecate constant visibility across the
autoload. It still is backwards compatible with setting the
private/deprecate constant visibility in the autoloaded file.
However, if you explicitly set public constant in the autoloaded
file, that will be reset after the autoload.

rb_eval_cmd takes a safe level, and now that $SAFE is deprecated,
it should be deprecated as well.
Replace with rb_eval_cmd_kw, which takes a keyword flag. Switch
the two callers to this function.
This removes the related tests, and puts the related specs behind
version guards. This affects all code in lib, including some
libraries that may want to support older versions of Ruby.
This removes the security features added by $SAFE = 1, and warns for access
or modification of $SAFE from Ruby-level, as well as warning when calling
all public C functions related to $SAFE.
This modifies some internal functions that took a safe level argument
to no longer take the argument.
rb_require_safe now warns, rb_require_string has been added as a
version that takes a VALUE and does not warn.
One public C function that still takes a safe level argument and that
this doesn't warn for is rb_eval_cmd. We may want to consider
adding an alternative method that does not take a safe level argument,
and warn for rb_eval_cmd.
Looking at the list of symbols inside of libruby-static.a, I found
hundreds of functions that are defined, but used from nowhere.
There can be reasons for each of them (e.g. some functions are
specific to some platform, some are useful when debugging, etc).
However it seems the functions deleted here exist for no reason.
This changeset reduces the size of ruby binary from 26,671,456
bytes to 26,592,864 bytes on my machine.
This function was created as a variant of st_copy with firing write
barrier.
It should have more explicit name, such as st_copy_with_write_barrier.
But because it is used only for copying iv_tbl, so I rename it to
rb_iv_tbl_copy now. If we face other use case than iv_tbl, we may want
to rename it to more general name.
Module#class_variables should reflect class variable lookup. For
singleton classes of classes/modules, this means the lookup should
be:
* Singleton Class
* Class
* All Ancestors of Class
Note that this doesn't include modules included in the singleton
class, because class variable lookup doesn't include those.
Singleton classes of other objects do not have this behavior and
always just search all ancestors of the singleton class, so do not
change the behavior for them.

After 5e86b005c0, I now think ANYARGS is
dangerous and should be extinct. This commit adds a function
prototype for rb_ivar_foreach. Luckily this change revealed no
problematic usage of the function.
After 5e86b005c0, I now think ANYARGS is
dangerous and should be extinct. This commit uses rb_gvar_getter_t /
rb_gvar_setter_t for rb_define_hooked_variable /
rb_define_virtual_variable which revealed lots of function prototype
inconsistencies. Some of them were literally decades old, going back
to dda5dc00cf.
After 5e86b005c0, I now think ANYARGS is
dangerous and should be extinct. This commit deletes ANYARGS from
rb_ensure, which also revealed many arity / type mismatches.
b00f280d4b introduced
an accidental behavior change in that defining a module/class under
`m` gives `m` a name when `m` is anonymous.
`ruby -ve 'Module.new { class self::A; end; p name }'` outputs a name
similar to `Module#inspect` when it should output `nil` like in Ruby
2.6.x.
* variable.c: Use `make_temporary_path` instead of `save_temporary_path`
when getting the name of the parent module.
* variable.c (rb_set_class_path): Delegate to `rb_set_class_path_string`
instead of duplicating the logic.
