#5734: possible handle leak in posix implementation copy_file_api
--------------------------------------+-------------------------------------
 Reporter: alexey.kutumov@… | Owner: bemandawes
     Type: Bugs | Status: new
Milestone: Boost 1.48.0 | Component: filesystem
  Version: Boost 1.47.0 | Severity: Problem
 Keywords: filesystem copy_file |
--------------------------------------+-------------------------------------
 There is possible handle leak in POSIX implementation of function
 '''copy_file_api'''.


 {{{
 ...
     if ((infile = ::open(from_p.c_str(), O_RDONLY))< 0)
       { return false; }

     struct stat from_stat;
     if (::stat(from_p.c_str(), &from_stat)!= 0)
       { return false; }
 ...
 }}}

 if '''::stat''' failed, then function exits without closing '''infile'''
 handle.


 This problem exists both in '''v3''' and '''v2''' implementations of
 filesystem. Also this problem exists in previous releases.
