Subject: git fails with a broken pipe when one quits the pager
Date: Fri, 15 Jan 2021 17:15:59 +0100 [thread overview]
Message-ID: <YAG/vzctP4JwSp5x@zira.vinc17.org> (raw)
I had reported the following bug at
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=914896
It still occurs with Git 2.30.0.
Some git commands with a lot of output fail with a broken pipe when
one quits the pager (without going to the end of the output).
For instance, in zsh:
cventin% setopt PRINT_EXIT_VALUE
cventin% git log
zsh: broken pipe git log
cventin% echo $?
141
cventin%
This is annoying. And of course, I don't want to hide error messages
by default, because this would hide *real* errors.
The broken pipe is internally expected, thus should not be reported
by git.
Just to be clear: this broken pipe should be discarded only when git
uses its builtin pager feature, not with a general pipe, where the
error may be important.
For instance,
$ { git log ; echo "Exit status: $?" >&2 ; } | true
should still output
Exit status: 141
like currently.
