One year ago, the former method has been deprecated while the latter
has become an error. Then the 3.1 released, it is enough time to make
also the former an error.
rb_ary_tmp_new suggests that the array is temporary in some way, but
that's not true, it just creates an array that's hidden and not on the
transient heap. This commit renames it to rb_ary_hidden_new.
Previously, because opt_aref and opt_aset don't push a frame, when they
would call rb_hash to determine the hash value of the key, the initial
level of recursion would incorrectly use the method id at the top of the
stack instead of "hash".
This commit replaces rb_exec_recursive_outer with
rb_exec_recursive_outer_mid, which takes an explicit method id, so that
we can make the hash calculation behave consistently.
rb_exec_recursive_outer was documented as being internal, so I believe
this should be okay to change.
[Feature #18683]
This allows parsers and similar libraries to create Hashes of
a certain capacity in advance. It's useful when the key and values
are streamed, hence `bulk_insert()` can't be used.
Method references is not only able to be marked up as code, also
reflects `--show-hash` option.
The bug that prevented the old rdoc from correctly parsing these
methods was fixed last month.
I used this regex:
([A-Za-z]+)\.html#(?:class|module)-[A-Za-z]+-label-([A-Za-z0-9\-\+]+)
And performed a global find & replace for this:
rdoc-ref:$1@$2
Before this change the write barrier was executed before the key and
value were actually reachable via the Hash. This could cause
inconsistencies in object coloration which would lead to accidental
collection of dup'd keys.
Example:
1. Object O is grey, Object P is white.
2. Write barrier fires O -> P
3. Write barrier does nothing
4. Malloc happens, which starts GC
5. GC colors O black
6. P is written in to O (now we have O -> P reference)
7. P is now accidentally treated as garbage
We found that we need to make Ruby objects while locking the environ
to ENV operation atomically, so we decided to use `RB_VM_LOCK_ENTER()`
instead of `env_lock`.
From the documentation of rb_obj_hash:
> Certain core classes such as Integer use built-in hash calculations and
> do not call the #hash method when used as a hash key.
So if you override, say, Integer#hash it won't be used from rb_hash_aref
and similar. This avoids method lookups in many common cases.
This commit uses the same optimization in rb_hash, a method used
internally and in the C API to get the hash value of an object. Usually
this is used to build the hash of an object based on its elements.
Previously it would always do a method lookup for 'hash'.
This is primarily intended to speed up hashing of Arrays and Hashes,
which call rb_hash for each element.

* As the "doc/" prefix is specified by the `--page-dir` option,
remove from the rdoc references.
* Refer to the original .rdoc instead of the converted .html.
Instead of looking for Object::ENV (which can be overwritten),
directly look for the envtbl variable. As that is static in hash.c,
and the lookup code is in process.c, add a couple non-static
functions that will return envtbl (or envtbl#to_hash).
Fixes [Bug #18164]
We don't need to increment/decrement iteration level for frozen Hash
because frozen Hash can't be modified. We can assume that nobody
changes the target Hash while calling #each family.
How to reproduce:
a = {}
100.times do |i|
a[i] = true
end
Ractor.make_shareable(a)
4.times.collect do
Ractor.new(a) do |b|
100.times do
b.each_value do
end
end
end
end.each(&:take)
Example output:

This makes the compare_by_identity setting always copied
for the following methods:
* except
* merge
* reject
* select
* slice
* transform_values
Some of these methods did not copy the setting, or only
copied the setting if the receiver was not empty.

ENV.dup returned a plain Object, since all of ENV's behavior is
defined in ENV's singleton class. So using dup makes no sense.
ENV.clone works and is used in some gems, but it doesn't do what
the user expects, since modifying ENV.clone also modifies ENV.
Add a deprecation warning pointing the user to use ENV.to_h
instead.
This also undefines some private initialize* methods in ENV,
since they are not needed.

This commit aims to cover following methods
* Hash#select!
* Hash#filter!
* Hash#keep_if
* Hash#reject!
* Hash#delete_if
I think these are not all.
---
* Ensure the receiver is modifiable or not
* Assert the receiver is not modified
* Windows: Read ENV names and values as UTF-8 encoded Strings
Implements issue #12650: fix https://bugs.ruby-lang.org/issues/12650
This also removes the special encoding for ENV['PATH'] and some
complexity in the code that is unnecessary now.
* Windows: Improve readablity of getenv() encoding
getenv() did use the expected codepage as an implicit parameter of the macro.
This is mis-leading since include/ruby/win32.h has a different definition.
Using the "cp" variable explicit (like the other function calls) makes it
more readable and consistent.
* Windows: Change external C-API macros getenv() and execv() to use UTF-8
They used to process and return strings with locale encoding,
but since all ruby-internal spawn and environment functions use UTF-8,
it makes sense to change the C-API equally.
While it is expected that all environment keys are unique, that is
not enforced. It is possible by manipulating environ directly you
can call a process with an environment with duplicate keys. If
ENV.replace was passed a hash with a key where environ had a
duplicate for that key, ENV.replace would end up deleting the key
from environ.
The fix in this case is to not assume that the environment key
list has unique keys, and continue processing the entire key
list in keylist_delete.
