2025-12-12Array#rfindKevin Newton
Implement Array#rfind, which is the same as find except from the other side of the Array. Also implemented Array#find (as opposed to the generic one on Enumerable because it is significantly faster and to keep the implementations together. [Feature #21678]

2024-11-26Optimize instructions when creating an array just to call `include?` (#12123)Randy Stauner
* Add opt_duparray_send insn to skip the allocation on `#include?` If the method isn't going to modify the array we don't need to copy it. This avoids the allocation / array copy for things like `[:a, :b].include?(x)`. This adds a BOP for include? and tracks redefinition for it on Array.

2024-08-22Don't use gc_impl.h inside of gc/gc.hPeter Zhu
Using gc_impl.h inside of gc/gc.h will cause gc/gc.h to use the functions in gc/default.c when builing with shared GC support because gc/gc.h is included into gc.c before the rb_gc_impl functions are overridden by the preprocessor. Notes: Merged: https://github.com/ruby/ruby/pull/11423
2024-07-03array.c: Remove outdated assertionsJean Boussier
Following [Feature #20589] it can happen that we change the capacity of a frozen array, so these assertions no longer make sense. Normally we don't hit them because `Array#freeze` shrinks the array, but if somehow the Array was frozen using `Object#freeze` then we may shrink it after it was frozen.
2024-07-02Add regression test for mutating pack's format stringAaron Patterson
It doesn't look like there was a test added for this bug, so I'm adding it. Code is from here: https://web.archive.org/web/20160908192307/http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-dev/24445
2024-04-14Resize ary when `Array#sort!` block modifies embedded aryZack Deveau
In cases where `rb_ary_sort_bang` is called with a block and tmp is an embedded array, we need to account for the block potentially impacting the capacity of ary. ex: ``` var_0 = (1..70).to_a var_0.sort! do |var_0_block_129, var_1_block_129| var_0.pop var_1_block_129 <=> var_0_block_129 end.shift(3) ``` The above example can put the array into a corrupted state resulting in a heap buffer overflow and possible segfault: ``` ERROR: AddressSanitizer: heap-buffer-overflow on address [...] WRITE of size 560 at 0x60b0000034f0 thread T0 [...] ``` This commit adds a conditional to determine when the capacity of ary has been modified by the provided block. If this is the case, ensure that the capacity of ary is adjusted to handle at minimum the len of tmp.
2024-03-04Disable callcc when ASAN is enabledKJ Tsanaktsidis
callcc's implementation is fundamentally incompatible with ASAN. Since callcc is deprecated and almost never used, it's probably OK to disable callcc when ruby is compiled with ASAN. [Bug #20273]
2024-02-22Skip under_gc_compact_stress on s390x (#10073)Takashi Kokubun
2023-12-21Fix ary_make_partial_step for compactionPeter Zhu
ary could change embeddedness due to compaction, so we should only get the pointer after allocations. The included test was crashing with: TestArray#test_slice_gc_compact_stress ruby/lib/pp.rb:192: [BUG] Segmentation fault at 0x0000000000000038
2023-11-29Array#rassoc should try to convert to array implicitly. Fixes #20003Tema Bolshakov
2023-11-27Fix compaction during ary_make_partialPeter Zhu
The ary_make_shared call may allocate, which can trigger a GC compaction. This can cause the array to be embedded because it has a length of 0.

2021-05-21Do not allow array modifications after freeze inside sort!Jeremy Evans
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.

2020-12-18Use category: :deprecated in warnings that are related to deprecationJeremy Evans
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.
