* Rationalise use of forks and pipes. fork_earlyPeter Stephenson2018-04-201-63/+16
| | | | | | | | | | | | | | | | | Ensure we _exit instead of returning from execcmd_exec() if we have forked. Before the optimisation code after the fork always ran to the check at the end, but that code is overkill for the logic between the early fork and the existing one. Remove old workaround to fork in caller of execcmd for current shell constructs as no longer needed with early fork below. Close input of newly created pipe on fork (destined for RHS of pipe which we never execute): this replaces a workaround from zsh-workers/32171, commit 9887fc3d7b. Set last1 on early fork as needed by some instances of shell constructs on LHS of pipeline to know they are exiting.

* Make early fork even earlier.Peter Stephenson2018-04-201-24/+25
| | | | | | It was after our preliminary scan of arguments to find a command. Actually, in the cases of early fork we don't need this information before forking.
* 42693: Fork early for pipelines.Peter Stephenson2018-04-201-3/+4
| | | | | | | If executing a command not at the end of a pipeline, and not optimised in the calling code, we can fork before "prefork" substitutions, at the same point as for background commands.
* 42684 (with extra comments): Fork early if in bg.Peter Stephenson2018-04-202-95/+140
| | | | | | | In execcmd the case of running the last command in a pipeline asynchronously for the purpose of & and &! is easy to work out, and we can avoid side effects and unnecessary execution time in the parent shell by forking earlier.
* 42686: Fix previous pgrp patch.Peter Stephenson2018-04-192-1/+7
| | | | | We shouldn't do any fix ups unless the process has actually exited.
* 42630: Improve process group handling in pipelines.Peter Stephenson2018-04-173-1/+34
| | | | | | | | | If process group leader exits, allow a newly forked process to become process leader. If a foreground job, reattach the shell to the terminal until that happens. Unblock signals when reading output for command subsitution so that we can do this reattaching immediately.
