* 52594: support for POSIX real-time signals with kill and trapOliver Kiddle2024-02-281-6/+78
| | | | Also add new -L option to kill for a more verbose listing of signals
* 52365: record state of exited background jobs so as to be visible in TRAPCHLDBart Schaefer2023-12-091-13/+3
|
* 50306: fix wait for child that was stopped/continuedJun-ichi Takimoto2022-06-031-6/+4
| | | | do not call addbgstatus() when child is stopped/continued
* 49029: Prevent shell from sending duplicate signals with MONITORErik Paulson2021-07-231-0/+1
|
* 48857: declare "volatile" all globals that may be modified by signal handlersBart Schaefer2021-05-161-8/+8
|
* users/24710: Fix job control problem with sudo.Peter Stephenson2020-02-271-1/+2
| | | | | | | If we use kill to test for continued existence of a process group, we should check on failure that the error is ESRCH, as EPERM indicates the group still has memebers but running privileged so should be left alone.
* 45058: internal: Add symbolic names to possible values of zexit()'s ↵Daniel Shahaf2019-12-171-4/+4
| | | | "from_where" parameter. No functional change.
* 44259: Ensure we can set signals to default even if ignored.Peter Stephenson2019-05-131-4/+0
| | | | | | Previously the shell didn't take account of signals marked as ignored on entry, which was inconsistent with other behaviour.
* 43535: Fixes for bg / fg handling of superjobs.Peter Stephenson2018-09-241-3/+19
| | | | | | | | | | | Be more consistent about marking both superjob and subjob as running when sending SIGCONT. Send SIGCONT to superjob / subjob combination any time it is put in foreground, even if thought running, since subjob may invisibly have suspended. When waiting for superjob, wait for subjob, too.
* 43464: Another attachtty() fix.Peter Stephenson2018-09-161-2/+3
| | | | | | | | | If list_pipe_job triggered more than once we need to know the most recent process group leader, so record that both if the attach happened in the main shell on in entersubsh(). Also don't pass back proocess group for ESUB_ASYNC subshells.
* Fix windowsize when reattaching to terminal on process exitPeter Stephenson2018-09-121-0/+1
|
* 433029: Testing signal return type is no longer neededEitan Adler2018-06-181-1/+1
|
* 42234: Stephane: don't kill a process if not running.Peter Stephenson2018-05-141-3/+15
| | | | This could happen when kiiling a job. The processs might be reused.
* 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.
* 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 Stephenson2018-04-171-0/+13
| | | | | | | | | 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.
* 41590 modified as 41595: make ERR_RETURN more logical.Peter Stephenson2017-08-241-1/+1
| | | | | | | | It now operates separately at each function depth. To keep ERR_EXIT global, make the noerrexit variable usd bit flags. Extend tests.
* 41012: Fix premature exit from nested function in EXIT trap.Peter Stephenson2017-04-271-0/+11
| | | | | | Also add check so we don't delay an exit if we were already in an EXIT trap for the main shell, as we should in that case leave immediately.
* 40624: conditionally handle WIFCONTINUED to properly set SP_RUNNING process ↵Barton E. Schaefer2017-02-231-0/+5
| | | | status
* 40353 with tweaks to whence -v: extend directory cache use.Peter Stephenson2017-01-161-2/+5
| | | | | | Now used for all autoloaded functions after load, including those where the file was found along fpath, reducing duplication of directory names.
* 40342: Add directory name cache for autoload file paths.Peter Stephenson2017-01-121-0/+1
| | | | | This renders "autoload /blah/blah/*" as efficient as use of fpath.
* 39548: DEBUG for queueing_enabledBarton E. Schaefer2016-10-031-0/+4
|
* 39436: Pass on status of SIGINT better.Peter Stephenson2016-09-251-0/+1
| | | | | | Set lastval to 128 + SIGINT on interrupt. Don't execute builtin if already interrupted at that point.
* 39359: Fix remaining race with orphaned subjob.Peter Stephenson2016-09-161-3/+13
| | | | | | When shell is forked to run right hand side of pipieline it should use its own PID as process group if the left hand side of the pipeline has already exited.
* 38094: Fix POSIX EXIT traps defined in function.Peter Stephenson2016-03-071-1/+6
| | | | | These aren't local, so set the local level to 0; else they can get overridden incorrectly.
* 38024: Improve POSIX and native EXIT traps compatibility.Peter Stephenson2016-02-251-1/+6
| | | | | | | Allow a nested function trap to leave save and restore a POSIX trap. Still fails if the POSIX trap was defined in a function.
* 37999: Sticky behaviour of EXIT traps.Peter Stephenson2016-02-171-9/+37
| | | | | | | | They now have POSIX or non-POSIX behaviour based on the setting of POSIX_TRAPS where the trap was defined, rather than where the trap would (or would not) be executed. Tweaks possible.
* 36393: process queued signals during dotrap()Barton E. Schaefer2015-09-021-0/+5
|
* 36079: do not allow update_job() and its helpers to run the signal queue ↵Barton E. Schaefer2015-08-101-0/+8
| | | | while we are processing a job exit.
* Don't rely on implicit value when saving background process statusPeter Stephenson2015-08-101-2/+8
|
* 36022 fix bug that some loop constructs could not be interrupted, revise ↵Barton E. Schaefer2015-08-091-2/+6
| | | | | | | | | | | signal queueing There are two underlying ideas here: (1) Keeping signals queued around anything that's doing memory management (including push/pop of the heap) has become crucial. (2) Anytime the shell is going to run a command, be it buitin or external, it must be both safe and necessary to process any queued signals, so that the apparent order of signal arrival and command execution is preserved.
* Rearrange context saving.Peter Stephenson2015-01-091-2/+2
| | | | | | | Variables are now associated with the module that declares them, being initialised and saved/restored there. However, as many variables are used for communication between modules, many of them are set in multiple places, so the assignment is ambiguous.
* 33876: etc.: Separate errors and keyboards interruptsPeter Stephenson2014-12-111-4/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Combination of 12 commits from interrupt_abort branch. Basic strategy is to introduce bits to errflag and to set and reset them separately. Remove interrupt status on return to main keymap. Turn off ERRFLAG_INT for always block. Restore bit thereafter: we probably need a new variable in order to allow user interrupts to be reset in the always block. Add TRY_BLOCK_INTERRUPT This works the same as TRY_BLOCK_ERROR, but for a SIGINT, too. Ensure propagation of SIGINT from exited job. If received by foreground job, shell uses ERRFLAG_INT, not ERRFLAG_ERROR, to set the new state. Reset errflag before precmd() Add always block in _main_completion to fix ZLS_COLORS Ensures we get the right state of $ZLS_COLORS at the end of _main_complete even if there's an interrupt. However, the "right state" is a bit messy as it depends on styles.
* 33531 with additions: retain status of exited background jobs.Peter Stephenson2014-10-261-7/+7
| | | | | | | | Add linked list of unwaited-for background jobs. Truncate at value of _SC_CHILD_MAX discarding oldest. Remove old lastpid_status mechanism for latest exited process only. Slightly tighten safety of permanently allocated linked lists so that this doesn't compromise signal handling.

* 32479: POSIXTRAPS and implicit return values.Peter Stephenson2014-03-141-0/+8
| | | | | | With POSIXTRAPS never propagate implicit return value. In any case if not forcing a return value don't use lastval from within the trap, use the one from the surrounding code.
