Description Eric Blake 2011-04-04 19:09:59 UTC

Description of problem:
POSIX requires that any utility that takes operands must accept and ignore -- as the first argument, to allow for alternate implementations that support options (unless explicitly documented otherwise, such as 'echo').

dirname is not explicitly documented otherwise; therefore, 'dirname a' and 'dirname -- a' are required by POSIX to behave identically.

Version-Release number of selected component (if applicable):
busybox-1.15.1-7.fc14.x86_64

How reproducible:
100%

Steps to Reproduce:
1. busybox dirname -- a
2. echo $?
  
Actual results:
BusyBox v1.15.1 (2010-05-05 10:58:54 UTC) multi-call binary

Usage: dirname FILENAME

Strip non-directory suffix from FILENAME
1

Expected results:
.
0

Comment 1 Denys Vlasenko 2011-07-20 12:31:47 UTC

This is fixed in upstream.

I guess it's time to release 1.19.0...

Comment 2 Denys Vlasenko 2011-11-01 12:42:57 UTC

1.19.3 is in rawhide now:

and it addresses this BZ
