Issue #19910 has been reported by segiddins (Samuel Giddins).
---------------------------------------- Bug #19910: Set#delete_if behavior inconsistent with Array/Hash https://bugs.ruby-lang.org/issues/19910
* Author: segiddins (Samuel Giddins) * Status: Open * Priority: Normal * ruby -v: 3.2.2 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Given the following script:
```ruby #!/usr/bin/env ruby
require 'set'
def enum(collection) i = 0 collection.delete_if do i += 1 raise ArgumentError if i == 6 i.odd? end rescue ArgumentError return collection end
pp enum([0, 1, 2, 3, 4, 5, 6, 7]) pp enum([0, 1, 2, 3, 4, 5, 6, 7].to_h { [_1, _1] }) pp enum([0, 1, 2, 3, 4, 5, 6, 7].to_set) ```
It results in:
``` [1, 3, 5, 6, 7] {1=>1, 3=>3, 5=>5, 6=>6, 7=>7} #<Set: {0, 1, 2, 3, 4, 5, 6, 7}> ```
As you can see, when an exception is raise inside `delete_if` on Hash/Array, the already-considered elements are still removed from the array. For `Set`, no elements are deleted (due to the implementation that builds up an intermediary list of elements to delete, then removes them from the underlying hash afterwards). It would be very helpful if `Set#delete_if` behaved consistently with other core collection types
