Subject: [PATCH] [SV 63307] Reset SIGPIPE in spawned children
|
||||
|
||||
* configure.ac: Check for posix_spawnattr_setsigdefault.
|
||||
* src/job.c (child_execute_job): Reset SIGPIPE in the child
|
||||
process.
|
||||
* src/job.h (sigpipe_ignored): Declare.
|
||||
* src/main.c (main): Remember if SIGPIPE was inherited as ignored.
