Patch by Panu Matilainen <pmatilai@redhat.com> for popt <= 1.16 which kludges
|
|
poptBadOption() to return something semi-meaningful on exec alias fail:
|
|
|
|
- poptBadOption() is totally unaware of exec alias failures, and will return
|
|
either the first argument or last option, giving wonderfully misleading error
|
|
messages (#697435, #710267).
|
|
- Remember execvp() first argument on failure and return that from
|
|
poptBadOption() if present to give the user a reasonable clue what exactly
|
|
went wrong.
|
|
|
|
This patch was proposed to upstream: http://rpm5.org/community/popt-devel/0264.html
