Bug 1237213

+++ This bug was initially created as a clone of Bug #1148507 +++

Description of problem:

Importing of functions that were previously exported with `export -f' fails if the function name contains a hyphen (i.e. '-').

Version-Release number of selected component (if applicable):

bash-4.1.2-15.el6_5.2

How reproducible:

Always:

[cperl@localhost /tmp]$ rpm -qa bash
bash-4.1.2-15.el6_5.2.x86_64
[cperl@localhost /tmp]$ foo-bar () { echo a; }
[cperl@localhost /tmp]$ foo-bar
a
[cperl@localhost /tmp]$ export -f foo-bar
[cperl@localhost /tmp]$ bash
bash: error importing function definition for `BASH_FUNC_foo-bar'
[cperl@localhost /tmp]$ 

Actual results:

Importing of previously exported functions whose name have a hyphen in them fails.

Expected results:

Importing of previously exported functions whose name have a hyphen in them should work.

Additional info:

This has been discussed in a few places already [1][2].  However, it looks like the latest upstream patch at [3] (bash 4.3, patch 27, git commit 3590145af6f1c9fa321dff231f69ae696e7e740b) actually fixes this.

I believe the relevant part of the patch is:

-         if (legal_identifier (name))
-           parse_and_execute (temp_string, name, SEVAL_NONINT|SEVAL_NOHIST|SEVAL_FUNCDEF|SEVAL_ONECMD);
+         if (absolute_program (tname) == 0 && (posixly_correct == 0 || legal_identifier (tname)))
+           parse_and_execute (temp_string, tname, SEVAL_NONINT|SEVAL_NOHIST|SEVAL_FUNCDEF|SEVAL_ONECMD);

Would it be possible to release a new bash 4.1 package for RHEL 6.5 with the patch updated to accommodate this change?

---------------------------------------------------------------------------

The same bug is present in RHEL 7.1. It shall be fixed here as upgrading from RHEL 6 (fixed) to RHEL 7 (unfixed) would cause regression.

Version-Release number of selected component (if applicable):

bash-4.2.46-12.el7
