| Summary | 0001940: ed should ignore (or handle) SIGPIPE | ||||
| Description | The specification for ed states in section ASYNCHRONOUS EVENTS that: "The ed utility shall take the standard action for all signals (...) with the following exceptions: SIGINT (...), SIGHUP (...), SIGQUIT (...)". But ed should also ignore (or handle) SIGPIPE to prevent commands like 'w !:' (writing to a shell command that does not read (all of) its standard input) from abnormally terminating ed without saving the changes. GNU ed prevents such unwanted termination by ignoring SIGPIPE and detecting a broken pipe just as any other write error. | ||||
| Desired Action | Add to section ASYNCHRONOUS EVENTS something like the following: SIGPIPE The ed utility shall ignore this event. | ||||

> GNU ed prevents such unwanted termination by ignoring SIGPIPE Is this a recent change? I tried it with GNU ed 1.19 from Debian bookworm and it was terminated by SIGPIPE. Also got SIGPIPE on Solaris 11.4 and macOS. I see that the standard says the behaviour on SIGPIPE for ex is unspecified, so perhaps we should do the same for ed. |

Before Issue 8 page 2816 line 93355 section ed (ASYNCHRONOUS EVENTS), insert:SIGPIPEThe behavior is unspecified. |
