Subject: Shell exits on bad coproc redirection
Date: Fri, 17 Aug 2001 15:42:51 +0000 [thread overview]
Message-ID: <1010817154252.ZM14094@candle.brasslantern.com> (raw)
This affects 3.0.8 and 4.0.1 as well as 4.1.0-dev-1, but NOT 3.0.6.
schaefer[503] Src/zsh -f
zagzig% echo $ZSH_VERSION
4.1.0-dev-1
zagzig% print >&p
zsh: coprocess: bad file descriptor
zagzig% coproc sleep 1
[1] 14033
zagzig%
[1] + done sleep 1
zagzig% print >&p
schaefer[504] echo $?
141
So the shell is dying of a SIGPIPE.
The problem seems to be a combination of these two items (ChangeLog-3.1):
1999-10-10 Bart Schaefer <schaefer@zsh.org>
* Src/exec.c: Plug lead of a copy of the coproc input descriptor.
(ahem, that should say "leak").
Sun May 18 18:57:08 1997 Zolt<E1>n Hidv<E9>gi <hzoli@cs.elte.hu>
* Src/builtin.c, Src/exec.c, Src/init.c, Src/signals.c, Src/jobs.c:
Do not handle SIGPIPE specially for shells with job control
Anybody remember why we stopped handling SIGPIPE? Is Zoltan still out there
anywhere?
