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.
Remove the listattr call in zgetattr, it only caused no error to be output
when trying to retrieve an xattr from a file with no xattrs. When a file
had xattrs, it would just add an extra syscall for no good reason.
Always set an array parameter in zlistattr, this makes the returned value
much easier to use; in fact the _zattr completer didn't account for this
and zlistattr foo <tab> on a file with only one attribute did not work.
Almost all of the patch is only reindent, the only modification that's
not a pure deletions is:
- ret = 1 + (attr_len > val_len || attr_len < 0);
+ ret = 1 + ((val_len > 0 && attr_len > val_len) || attr_len < 0);
which makes sure we return the correct error in the new path due to the
removed listattr call. (If val_len is -1 due to no attribute existing,
it doesn't mean the user should retry the call because the attribute
grew in size).
Shell functions are strictly ASCII for maximum portability.
Other files within the distribution may contain UTF-8 characters.
Exception for test files: where they need single character input
with the top bit set, ISO-8859-X is used (X doesn't matter as
we don't need the Euro).
