Description
When a error is raised in some class methods of Dir
, the backtrace is as if the user called Dir.open
.
$ ruby -e 'Dir.foreach {}'
Traceback (most recent call last):
2: from -e:1:in `<main>'
1: from -e:1:in `foreach'
-e:1:in `open': wrong number of arguments (given 0, expected 1) (ArgumentError)
$ ruby -e 'Dir.foreach(nil)'
Traceback (most recent call last):
2: from -e:1:in `<main>'
1: from -e:1:in `foreach'
-e:1:in `open': no implicit conversion of nil into String (TypeError)
$ ruby -e 'Dir.foreach("not_exist")'
Traceback (most recent call last):
2: from -e:1:in `<main>'
1: from -e:1:in `foreach'
-e:1:in `open': No such file or directory @ dir_initialize - not_exist (Errno::ENOENT)
The last line of the error message should be -e:1:in `foreach': ...
like IO.foreach
This occurs in following methods:
Dir.foreach
Dir.entries
Dir.each_child
Dir.children

It is expected as these methods delegate to Dir.open
.
So you can redefine the open
method.
$ ruby -e 'def Dir.open(*)raise "boom";end; Dir.foreach("."){}'
Traceback (most recent call last):
2: from -e:1:in `<main>'
1: from -e:1:in `foreach'
-e:1:in `open': boom (RuntimeError)
whereas IO.foreach
can't.

I'm not sure this difference between IO
and Dir
is intentional.
