[ruby-core:80287] [Ruby trunk Bug#13222] Array#sum inconsistency when init value is non-numeric
From:
mtsmfm@...
Date:
2017-03-23 02:00:36 UTC
List:
ruby-core #80287
Issue #13222 has been updated by mtsmfm (Fumiaki Matsushima).
I confirmed this behavior appears not only 2.5.0dev but also 2.4.x.
~~~
$ docker run ruby:2.4.1 ruby -e "p [0].sum('a')"
"a"
~~~
~~~
$ docker run ruby:2.4.0 ruby -e "p [0].sum('a')"
"a"
~~~
Should we backport the patch?
----------------------------------------
Bug #13222: Array#sum inconsistency when init value is non-numeric
https://bugs.ruby-lang.org/issues/13222#change-63739
* Author: matsuda (Akira Matsuda)
* Status: Closed
* Priority: Normal
* Assignee:
* Target version:
* ruby -v: ruby 2.5.0dev (2017-02-17 trunk 57644) [x86_64-darwin15]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------
Since Array#sum skips calling plus for `0` https://github.com/ruby/ruby/blob/c85a58d/array.c#L5831-L5832, it doesn't raise when the receiver array consists of 0 only, even when the "init" value is non-numeric.
```
% ruby -e "p [1].sum('a')"
-e:1:in `sum': String can't be coerced into Integer (TypeError)
```
```
% ruby -e "p [0].sum('a')"
"a"
```
```
% ruby -e "p [0, 0, 0].sum('a')"
"a"
```
