[ruby-core:93049] [Ruby trunk Bug#15664] File.executable returns incorrect results in Windows 10

[merch-redmine]

Issue #15664 has been updated by jeremyevans0 (Jeremy Evans).

File file-executable-doc.patch added

Unlike Unix, Windows doesn't support execute permissions separately. If the path is a regular file, Ruby currently uses file extensions to determine if a file is executable, and only considers the following extensions as executable: `.bat`, `.cmd`, `.com`, `.exe`.  See https://github.com/ruby/ruby/blob/trunk/win32/win32.c#L5598-L5602

I don't think this is fixable unless we want to make `File.executable?` an alias to `File.readable?` on Windows, and that would just result in the opposite issue, with `File.executable?` returning `true` for files that are just readable and not actually executable.

The documentation for `File.executable` and `File.executable_real?` does not currently reflect the issues on Windows.  Attached is a documentation patch to explain the behavior.  I plan to commit this in about a week unless I hear objections.

Issue #15664 has been updated by nobu (Nobuyoshi Nakada).


I agree on the documentation fix, but I guess that `Gem.bin_path` should return the proper stub file path in this case.
