From d067ebcacd55472f720b2765ec686a69b25c9a90 Mon Sep 17 00:00:00 2001 From: Peter Stephenson Date: Sun, 7 Dec 2014 16:24:19 +0000 Subject: 33876: etc.: Separate errors and keyboards interrupts 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. --- Src/glob.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'Src/glob.c') diff --git a/Src/glob.c b/Src/glob.c index b3903f2ff..82f8d626c 100644 --- a/Src/glob.c +++ b/Src/glob.c @@ -682,7 +682,7 @@ parsecomplist(char *instr) /* Now get the next path component if there is one. */ l1 = (Complist) zhalloc(sizeof *l1); if ((l1->next = parsecomplist(instr)) == NULL) { - errflag = 1; + errflag |= ERRFLAG_ERROR; return NULL; } l1->pat = patcompile(NULL, compflags | PAT_ANY, NULL); @@ -728,7 +728,7 @@ parsecomplist(char *instr) return (ef && !l1->next) ?
