f94c9bf288 tar: fix bug 673 (misdetection of repeated dir as hardlink). +92 bytes
While at it, remove many superfluous ops on unpack:
mkdir("."), lots of umask() calls. Can remove more
by caching username->uid.

582dff0514 volume identification: abolish /proc/partitions and /proc/cdroms
scanning. It does not catch volume managers and such.
Adding even more cruft is bad, so I decided to simply
scan /dev/* for any block devices. See how much better
it finds devices now:

0e020d1025 Make certain clients of bb_make_directory default to honoring
the user's umask
2004-10-13 06:25:52 +00:00

2842659cc0 Patch from Michael Tokarev:
Scenario:

  touch x -- creates plain file name `x'
  mkdir x -- exits successefully

libbb/make_directory.c, bb_make_directory(), contains
the following code:

        if (mkdir(path, 0777) < 0) {
            /* If we failed for any other reason than the directory
             * already exists, output a diagnostic and return -1.*/
            if (errno != EEXIST) {
                fail_msg = "create";
                umask(mask);
                break;
            }
            /* Since the directory exists, don't attempt to change
             * permissions if it was the full target.  Note that
             * this is not an error conditon. */
            if (!c) {
                umask(mask);
                return 0;
            }
        }

The assumption that EEXIST error is due to that the *directory*
already exists is wrong: any file type with that name will cause
this error to be returned.  Proper way IMHO will be is to stat()
the path and check whenever this is really a directory.  Below
(attached) is a patch to fix this issue.

This is a bulk spelling fix patch against busybox-1.00-pre10.
If anyone gets a corrupted copy (and cares), let me know and
I will make alternate arrangements.

Erik - please apply.

Authors - please check that I didn't corrupt any meaning.

Package importers - see if any of these changes should be
passed to the upstream authors.

I glossed over lots of sloppy capitalizations, missing apostrophes,
mixed American/British spellings, and German-style compound words.

What is "pretect redefined for test" in cmdedit.c?

Good luck on the 1.00 release!
