* Rearrange context saving.Peter Stephenson2015-01-091-4/+4
| | | | | | | 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 Stephenson2014-12-111-21/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Treat exec from subshell as if forkedPeter Stephenson2014-11-021-0/+9
| | | | | This removes weird behaviour when optimising the last command. In particular SHLVL is correct from a subshell executed as the last command.
* 33531 with additions: retain status of exited background jobs.Peter Stephenson2014-10-261-2/+0
| | | | | | | | 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.
