* Rearrange context saving.Peter Stephenson2015-01-091-3/+80
| | | | | | | 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.
* Fix command substitutions to parse contents as they are read in.Peter Stephenson2015-01-081-9/+20
| | | | | | | Do this by refactoring misnamed lexsave()/lexrestore() to allow continuity of history and input. Add test.
* 33876: etc.: Separate errors and keyboards interruptsPeter Stephenson2014-12-111-15/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 33345: fix anonymous function complex command handling.Peter Stephenson2014-10-031-83/+84
| | | | | | Longstanding problem caused simple anonymous function incorrectly to reset the overall "complext" state, causing wordcode to be diverted into execsimple(), which caused a crash 'cos ist wasn't simple.

* 33343: Variant anonymous function synax with arguments.Peter Stephenson2014-10-031-7/+24
| | | | Don't expand arguments as if in command position. Test.

* 32609: [[ $var ]] behaves as [[ -n $var ]] for bash/ksh compatibilityBarton E. Schaefer2014-05-131-13/+28
| | | | | | Also restore ksh [ -t ] compatibility when POSIX_BUILTINS is not set, and allow operators defined by modules to be called with no arguments, although this affects only runtime interpretation, not parsing.
* 32552 (updated by 32560): fix segfault when using process substitution in ↵Andrew Waldron2014-04-181-2/+2
| | | | | | anonymous function argument list Also disallow process substitution in function name position.
* 31696: In "test" No One Can Hear If You Shriek.Peter Stephenson2013-09-041-3/+11
| | | | Treat ! as a string in "test ! -a ..." and "test ! -o ...".
* 31574: alternative fix for bad fd if no FD_CLOEXEC.Peter Stephenson2013-07-251-8/+16
| | | | Remove dump records more consistently in that case.
* 31545: Use of FD_CLOEXEC to remove possibility of fd reuse.Peter Stephenson2013-07-201-0/+7
| | | | | File descriptors of mmap'd dump files are closed if and only if an exec is performed.
