This has a few benefits. First, it fixes a race condition when killing old processes in 'eshell-command'. Second, the "wait" built-in command is now more useful. Finally, killing processes when exiting Eshell (via 'eshell-round-robin-kill') should be much faster. * lisp/eshell/esh-proc.el (esh-opt): Require. (eshell-wait-for-process): Make obsolete in favor of... (eshell-wait-for-processes): ... this. Accept a timeout and support PIDs. Update callers. (eshell/wait): New implementation accepting -t/--timeout. (eshell-round-robin-kill): Use 'eshell-wait-for-processes'. * lisp/eshell/eshell.el (eshell-command): Use 'eshell-round-robin-kill'. * doc/misc/eshell.texi (List of Built-ins): Document the new "wait" behavior. * etc/NEWS: Announce this change. |
