source: MondoRescue/branches/stable/mondo/src/mondoarchive/mondo-cli.c@ 1663

Last change on this file since 1663 was 1663, checked in by Bruno Cornec, 17 years ago
  • Fix bug #197 (based on an initial patch of Scott Cummings)
  • Fix a bug where df was using locale to print messages and wasn't filtered correctly
  • mkdtemp checked in configure
  • reset_bkpinfo called as early as possible by both main program.
  • It creates a tmpdir cleanly with mkdtemp in setup_tmpdir subfunction, which takes in account TMPIR and TMP env var. Remains to see what tmpfs does and tests
  • configure.in should also be filtered.
  • Remove g_bkpinfo_DONTUSETHIS
  • remove bkpinfo also from header files
  • Render bkpinfo global (potential issue on thread, but should not be a problem as that structure is indeed static during archive)
  • Apply patch from Andree Leidenfrost, modified a bit to use bkpinfo->tmpdir instead of /tmp or MINDI_CACHE when appropriate. Fix security issues in mondo. Thanks al ot Andree for catching all those issues.
  • /tmp => /var/log for mondorestore.log in mindi
  • Update linux terminfo to fix a color issue (Andree Leidenfrost)
  • Removes useless log file (Andree Leidenfrost)
  • replace vi with find_my_editor during restore (Andree Leidenfrost)
  • sync in bg in mindi (VMWare issue to look at)
  • mindi/mindi-busybox have a different version than mondo for pb
  • PB-SUF also added to spec file
  • Fix a bug for pb build (omission of PB-SUF declaration)
