(Steps to reproduce your issue) used `git log`, exiting the viewer (`less`) before reading the entire commit history of the project What did you expect to happen? (Expected behavior) normal exit with status code 0 What happened instead? (Actual behavior) git log dies to SIGPIPE after `less` exits What's different between what you expected and what actually happened? git does not exit normally as would be expected Anything else you want to add: [System Info] git version: git version 2.30.2 cpu: x86_64 no commit associated with this build sizeof-long: 8 sizeof-size_t: 8 shell-path: /bin/sh uname: Linux 5.10.0-8-amd64 #1 SMP Debian 5.10.46-2 (2021-07-20) x86_64 compiler info: gnuc: 10.2 libc info: glibc: 2.31 $SHELL (typically, interactive shell): /bin/zsh ``` ## Jeff King, 2021-08-02 18:08 Subject: Re: BUG: git log dies to SIGPIPE Message-ID: URL: https://gitlist.dev/e/YQg0t2bzqwBJ02yL%40coredump.intra.peff.net In-Reply-To: ``` On Mon, Aug 02, 2021 at 10:46:53AM -0700, Joseph Jenne wrote: > What did you do before the bug happened?

I now know that it comes from outside git, this is really bad. -- ZheNing Hu ``` ## Ævar Arnfjörð Bjarmason, 2021-09-27 00:29 Subject: Re: BUG: git log dies to SIGPIPE Message-ID: <87y27i273e.fsf@evledraar.gmail.com> URL: https://gitlist.dev/e/87y27i273e.fsf%40evledraar.gmail.com In-Reply-To: ``` On Sun, Sep 26 2021, ZheNing Hu wrote: > Joseph Jenne 于2021年8月3日周二 上午1:47写道： >> >> What did you do before the bug happened?

Please see the discussion starting at https://lore.kernel.org/git/YAG%2FvzctP4JwSp5x@zira.vinc17.org/ about whether this is even considered a bug, but in any case the causes are well understood. ```
