* 36022 fix bug that some loop constructs could not be interrupted, revise ↵Barton E. Schaefer2015-08-091-2/+10
| | | | | | | | | | | 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.
* 35910: Don't add to raw lex buffer if lex stopped.Peter Stephenson2015-07-251-1/+2
| | | | | This was causing a segmentation violation in completion when parsing an incomplete math expression, e.g. 'echo $((3*4)<TAB>'.
* 35668: Improved fix for command/proc subst starting in alias.Peter Stephenson2015-07-021-1/+1
| | | | | | Use input flag to suppress the unwanted backtracking. Add test for the extra case covered.

* 34543: Prevent crash on garbage bytes inside $(...)Barton E. Schaefer2015-02-141-2/+4
| | | | | | Garbage input (nul bytes, etc.) can cause the $(...) parser to become confused during look-ahead and attempt to back up the input too far. This commit catches the error but does not fix the underlying cause.
* 34220: new $(...) handling needs to back up over alias expansionPeter Stephenson2015-01-101-0/+6

* Fix command substitutions to parse contents as they are read in.Peter Stephenson2015-01-081-5/+8
| | | | | | | Do this by refactoring misnamed lexsave()/lexrestore() to allow continuity of history and input. Add test.
* 33876: etc.: Separate errors and keyboards interruptsPeter Stephenson2014-12-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Check the return value of all pipe(), read(), and write() calls.Wayne Davison2009-12-161-1/+1
