* 43409: Fix process group setting in main shell.Peter Stephenson2018-09-072-21/+37
| | | | | | | | | A newly forked subshell now reports back the process group it will be using for the main shell to record. This prevents an error where the shell incorrectly thought an exiting process owned the terminal and so grabbed it back, putting the foreground process into the background.
* CVE-2018-0502, CVE-2018-13259: Fix two security issues in shebang line parsing.Anthony Sottile2018-09-031-16/+20
| | | | | | See NEWS for more information. Patch by Anthony Sottile and Buck Evan.
* Don't handle ZLE functions for single key.Peter Stephenson2018-09-034-16/+16
| | | | | | For read -k and read -q where we use ZLE, we just want a single key and not full ZLE processing. So don't handle timed ZLE functions when preforming the read.

| | | | | | | | Remove warnings of unused values as we always check the finally result later. Put segid before setuid as the setgid could fail if UID no longer privileged.

| | | | | | Previously it failed with an error message that the function was already defined. This is inconsistent with most other aspects of shell usage.

* unposted (branch fork_early): Fork early for pipelines.Peter Stephenson2018-05-011-82/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|
* 42708: fix for process substitution.Peter Stephenson2018-04-243-10/+18
| | | | | | | | | 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 Stephenson2018-04-231-1/+2
| | | | | | 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.

* 42684 (with extra comments): Fork early if in bg.Peter Stephenson2018-04-201-95/+135
| | | | | | | 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 Stephenson2018-04-191-1/+2
| | | | | We shouldn't do any fix ups unless the process has actually exited.
* 42630: Improve process group handling in pipelines.Peter Stephenson2018-04-172-1/+29
| | | | | | | | | 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.
* 42650: fix 42156 for zero-sized terminalsBarton E. Schaefer2018-04-151-5/+7
