Subject cvs commit: apache-2.0/src/os/os2 util_os2.c
Date Sun, 06 Aug 2000 15:07:43 GMT
bjh         00/08/06 08:07:42

  Modified:    src/os/os2 util_os2.c
  Log:
  Some enhancements for OS/2 ap_canonical_filename:
  - Log proper error message instead of error code on failure
  - In case of error caused by an invalid file name, don't return an empty
    string as that tends to confuse things rather than make them better.
  - Avoid using the very expensive ap_os_systemcase_canonical_filename()
    unless it's truely necessary.
