Unblock signals in forked scriptlets
|
|
|
|
Since commit c5f82d3f6223ebd0c5cc0a07ea60393ae7284929 we've blocked
|
|
most signals during transactions, which makes sense to rpm itself but
|
|
the signal mask is inherited to childs and carried even across exec(),
|
|
so all scriptlets are executing with those signals blocked as well.
|
|
Which in turn does not make sense, the scriptlets could run stuff that
|
|
actually depends on signal delivery (such as SIGALARM in RhBug:1913765).
|
|
|
|
Unblock all signals for forked scriptlet execution (Lua scriptlets are
|
|
totally different as they execute in-process for now)
