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.
