source: branches/stable/mondo/src/mondorestore/mondo-rstr-compare.c @ 1670

Last change on this file since 1670 was 1670, checked in by bruno, 12 years ago
  • Try to fix the issue with large exclude list (> 1000 chars) Some variables created after exclude_path (indirectly) were not sized big enough to handle them.
  • Remove useless .keep file
  • remove temporary.iso name remaining and suppress a warning in log trying to remove it in the tmpdir
  • missing extern bkpinfo in newt-specific.c
  • Attempt to fix #191 (allow edition of mountlist in compare mode)

(merge -r1662:1669 $SVN_M/branches/2.2.5)

  • Property svn:keywords set to Id
