Recursive copying symlinks

  • I ran into a big problem launching a duplicate site because it kept failing to copy tables because (as it said) my filesystem was full (mysql error 28). But because the plugin reverts all its changes after a DB failure, I could never see that the filesystem was actually full.

    It turns out that in the act of copying site files from uploads during the duplicate, it was creating a copy of files in a symlink folder that I had set up (hosted on a partition other than root) for the source site. These are large video files shared by several sites in the network. So when your plugin copied them instead of copying the symlink, that was the root cause of the error.

    May I suggest a change in your MUCD::Files::recurse_copy function to handle encountered symlinks differently than folders? For example:

    if ( is_link($src . '/' . $file) ) {
  symlink(readlink($src . '/' . $file, $dst);
} elseif ( is_dir($src . '/' . $file) ) {
...
