* 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.

* 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.
