* unposted (branch fork_early): Fork early for pipelines.Peter Stephenson2018-05-011-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Move fork before our preliminary scan of arguments to find a command: in the cases of early fork we don't need this information before forking. Ensure we _exit if forked in execcmd_exec(). Rationalise use of forks and pipes. 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.

* c.f. 42726: Back off fg and bg tests.Peter Stephenson2018-04-261-0/+5
| | | | | | | | | This is too hard to make robust. Problems include - Reading input in different places causes lines to appear and disappear - There is no easy way to sequence the asynchronous operations following bg. - Response to job control of user commands on some OSes (MacOS, for example) is unpredicatble.
* 42722: Replace ed with dc in fg/bg tests.Peter Stephenson2018-04-251-0/+3
| | | | | | This should be even simpler. Also more fix ups for failed pattern diffs.
* unposted: Correct process substitution buffer size in the PATH_DEV_FD codepath.Daniel Shahaf2018-04-251-0/+5
|
* 42714: Add fg and bg tests.Peter Stephenson2018-04-251-0/+6
| | | | | | | Use ed to get minimal user interaction without needing advanced terminal handling. Improve test output of failures of pattern differences.
* 42708: fix for process substitution.Peter Stephenson2018-04-241-0/+7
| | | | | | | | | Don't close associated file descriptors in the closem() tidy up function as they should remain visible to external processes. Override if about to exit. Unit test for the failing case: note this relies on the existence of /proc/self/fd or equivalent.
* 42705: Another safety fix for pgrp reclaiming.Peter Stephenson2018-04-231-0/+3
| | | | | | Only do this if killpg(dead_pid, 0) returns -1, indicating the pgprp doesn't exist any more, else there is a race if other proceses have started using it.
* Allow short loops with "while"Peter Stephenson2018-04-231-0/+4
|
* 42684 (with extra comments): Fork early if in bg.Peter Stephenson2018-04-201-0/+5
| | | | | | | 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 Stephenson2018-04-191-0/+5
| | | | | We shouldn't do any fix ups unless the process has actually exited.
* 42630: Improve process group handling in pipelines.Peter Stephenson2018-04-171-0/+5
| | | | | | | | | 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.
