# DP: upstream patch bash30-003
BASH PATCH REPORT
=================
Bash-Release: 3.0
Patch-ID: bash30-003
Bug-Reported-by: Egmont Koblinger <egmont@uhulinux.hu>
Bug-Reference-ID: <Pine.LNX.4.58L0.0407290044500.12603@sziami.cs.bme.hu>
Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2004-07/msg00279.html
Bug-Description:
Bash no longer accepts the `trap signum' syntax when in POSIX mode. This
patch restores a measure of backwards compatibility.
Patch:

*** 5954,5958 ****
The @code{trap} builtin doesn't check the first argument for a possible
signal specification and revert the signal handling to the original
! disposition if it is. If users want to reset the handler for a given
signal to the original disposition, they should use @samp{-} as the
first argument.
--- 5967,5972 ----
The @code{trap} builtin doesn't check the first argument for a possible
signal specification and revert the signal handling to the original
! disposition if it is, unless that argument consists solely of digits and
! is a valid signal number. If users want to reset the handler for a given
signal to the original disposition, they should use @samp{-} as the
first argument.
