Subject: [ruby-core:27928] [Bug #2669] mkmf find_executable doesn't find .bat files

Issue #2669 has been updated by Hugh Sasse.


Under cygwin, I have lots of .bat files which are not executable (according to ls -l).  Indeed, under Ruby 1.8, my rdoc.bat is not:

hgs@Q2P14HGS /bin
12:58:47$ ls -ld rdoc.bat
-rw-r--r-- 1 hgs None 141 Apr 27  2009 rdoc.bat

hgs@Q2P14HGS /bin
12:58:59$ wc !$
wc rdoc.bat
  6  26 141 rdoc.bat

hgs@Q2P14HGS /bin
12:59:17$ more rdoc.bat
@ECHO OFF
IF NOT "%~f0" == "~f0" GOTO :WinNT
@"ruby.exe" "/usr/bin/rdoc" %1 %2 %3 %4 %5 %6 %7 %8 %9
GOTO :EOF
:WinNT
@"ruby.exe" "%~dpn0" %*

hgs@Q2P14HGS /bin
12:59:23$ file rdoc.bat
rdoc.bat: MS-DOS batch file text

hgs@Q2P14HGS /bin
13:01:54$

In fact, most in /cygwin/bin are not executable
according to ls.  And...

hgs@Q2P14HGS /bin
13:05:07$ irb
irb(main):001:0> File.executable?('/bin/rdoc.bat')
=> false
irb(main):002:0> 

So we have one part of Ruby installing batch files to be executed, and another part saying they are not executable.  True, they are not marked as executable according to the bits.
Does this mean we need another method of File, to distinguish these cases?  If so, then we probably need to think about the Windows Scripting Host.
