The following issue has been SUBMITTED. ====================================================================== http://public.kitware.com/Bug/view.php?id=14609 ====================================================================== Reported By: irwin Assigned To: ====================================================================== Project: CMake Issue ID: 14609 Category: CMake Reproducibility: always Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 2013-11-30 18:41 EST Last Modified: 2013-11-30 18:41 EST ====================================================================== Summary: cmake -E copy and cmake -E copy_directory commands need an option to NOT follow symlinks on Linux Description: It is known but not documented (see bug 13204) that both "cmake -E copy" and "cmake -E copy_directory" currently follow symlinks on Linux. This results in a particularly bad situation when attempting to copy a directory that happens to contain a broken symlink, e.g.,
software@raven> ls -l test_symlink total 0 lrwxrwxrwx 1 software software 3 Nov 30 13:29 new -> old software@raven> cmake -E copy_directory test_symlink test_symlink1 Error copying directory from "test_symlink" to "test_symlink1". When I encountered this much too generic error message when using copy_directory for a very large directory recently I initially had no idea whether I was dealing with an i/o error or whatever, and it is only by chance that I discovered a botched exit from emacs in that directory had created a broken symlink. Thus, at minimum bug 13204 should be fixed and also copy_directory (and copy) should have a much more specific error message identifying both the symlink and the non-existent file that is causing the trouble. In addition, a (Unix-only) option to NOT follow symlinks should also be implemented for copy_directory and copy. After all, every GNU utility by default does not follow symlinks on Unix so it would be nice if at least this option was implemented for the cmake -E copy_directory and cmake -E copy commands on Unix. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2013-11-30 18:41 irwin New Issue ====================================================================== -- Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://public.kitware.com/cgi-bin/mailman/listinfo/cmake-developers
