ary_discard should not be used as it should be handled by the GC. The
only user of ary_discard is rb_ary_product, which doesn't neeed to use
ary_discard.
The RARRAY_LITERAL_FLAG was added in commit
5871ecf956 to improve CoW performance for
array literals by not keeping track of reference counts.
This commit reverts that commit and has an alternate implementation that
is more generic for all frozen arrays. Since frozen arrays cannot be
modified, we don't need to set the RARRAY_SHARED_ROOT_FLAG and we don't
need to do reference counting.
Array created as literals during iseq compilation don't need a
reference count since they can never be modified. The previous
implementation would mutate the hidden array's reference count,
causing copy-on-write invalidation.
This commit adds a RARRAY_LITERAL_FLAG for arrays created through
rb_ary_literal_new. Arrays created with this flag do not have reference
count stored and just assume they have infinite number of references.

This commit enables Arrays to move between size pools during compaction.
This can occur if the array is mutated such that it would fit in a
different size pool when embedded.
The move is carried out in two stages:
1. The RVALUE is moved to a destination heap during object movement
phase of compaction
2. The array data is re-embedded and the original buffer free'd if
required. This happens during the update references step
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.
This commit implements arrays on Variable Width Allocation. This allows
longer arrays to be embedded (i.e. contents directly follow the object
header) which improves performance through better cache locality.
rb_ary_reset could leave the array in a bad state since it frees memory
but does not unset any flags. This can cause a crash on GC stress. This
commit changes rb_ary_reset to set the array as an empty embedded array.
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
* 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.
This prevents early collection of the array. The GC doesn't see the
array on the stack when Ruby is compiled with optimizations enabled
[ruby-core:105099] [Bug #18140]
Commit 4f24255 introduced a bug which allows a length to be passed to
rb_ary_new4 which is too large, resulting in invalid memory access.
For example:
(1..1000).to_a.slice!(-2, 1000)
If freezing an array inside sort!, previously the array could be
modified after the freeze. This checks whether the receiver is
frozen after every yield and potential call to #> or #<,
preventing modifications if the receiver is frozen inside the
block or by the #> or #< call.
Fixes [Bug #17739]
Reallocating to a smaller size in the transient heap may result in no
change in the actual capacity but the capacity of the array is still
updated to the smaller value.
This commit changes `ary_heap_realloc` to return the new capacity which
can be used by the caller to correctly update the capacity.
Also document that both :deprecated and :experimental are supported
:category option values.
The locations where warnings were marked as deprecation warnings
was previously reviewed by shyouhei.
Comment a couple locations where deprecation warnings should probably
be used but are not currently used because deprecation warning
enablement has not occurred at the time they are called
(RUBY_FREE_MIN, RUBY_HEAP_MIN_SLOTS, -K).
Add assert_deprecated_warn to test assertions. Use this to simplify
some tests, and fix failing tests after marking some warnings with
deprecated category.
ractor_copy() used rb_ary_modify() to make sure this array is not
sharing anything, but it also checks frozen flag. So frozen arrays
raises an error. To solve this issue, this patch introduces new
function rb_ary_cancel_sharing() which makes sure the array does not
share another array and it doesn't check frozen flag.
[Bug #17343]
A test is quoted from https://github.com/ruby/ruby/pull/3817
* Support ArithmeticSequence in Array#slice
* Extract rb_range_component_beg_len
* Use rb_range_values to check Range object
* Fix ary_make_partial_step
* Fix for negative step cases
* range.c: Describe the role of err argument in rb_range_component_beg_len
* Raise a RangeError when an arithmetic sequence refers the outside of an array
[Feature #16812]
RARRAY_AREF has been a macro for reasons. We might not be able to
change that for public APIs, but why not relax the situation internally
to make it an inline function.
Adds a full discussion of #dig, along with links from Array, Hash, Struct, and OpenStruct.
CSV::Table and CSV::Row are over in ruby/csv. I'll get to them soon.
The art to the thing is to figure out how much (or how little) to say at each #dig.
