Subject: [ruby-core:35980] [Ruby 1.9 - Feature #2190] FileUtils::chmod - allow symbolic mode


Issue #2190 has been updated by Motohiro KOSAKI.


I slightly change the testcase at r31415. because FreeBSD don't change sticky bit.

Thx.

Feature #2190: FileUtils::chmod - allow symbolic mode
http://redmine.ruby-lang.org/issues/2190

Status: Closed
Priority: Normal

Target version: 1.9.x

 Hello,
 
 I request that FileUtils::chmod() and FileUtils::chmod_R() accept 
 symbolic modes, which are strings like "u+x,g-w,o=" (see "symbolic 
 mode" in `man chmod` for details), in addition to the numeric modes 
 they currently accept.
 
 If my request is fulfilled, the following would be equivalent:
 
   FileUtils::chmod(0712, "file.txt")
 
   FileUtils::chmod("u=rwx,g=x,o=w", "file.txt")
 
 In addition, symbolic modes would allow delta/patch changes:
 
   FileUtils::chmod("g+w", "file.txt")
 
 This is not so easy with numeric modes, because you must
 first read the current mode, apply your delta/patch mode
 using a bitwise OR operation, and finally apply the new
 numeric mode using FileUtils::chmod().
 
 Thanks for your consideration.
