a62e1640bc 39958: Add extra byte to PATH_MAX allocations. 
This ensures we've got enough space for a null, although this
isn't always needed.
 2016-11-17 19:49:17 +00:00
Barton E. Schaefer
98b7960c78 39943: no need to compute arrlen() in arrdup_max() when max == 0. 2016-11-15 10:04:14 -08:00
Peter Stephenson
921b39ac6b 39949: Special case for "-" in directory names. 
It can be sh-tokenized to Dash to allow for appearing in ranges
after substitution, so needs to be turned back to "-" in that case.

99acd1e7f4 39906: More multibyte optimisations for US-ASCII. 
This treats characters 0 to 0x7f as single byte US-ASCII along
the lines we already do in other places in the code.
 2016-11-14 10:12:04 +00:00
Peter Stephenson
a1633e09a7 39886 based on 39877: Optimise arrdup to arrdup_max. 
Only duplicate as much of the array as is needed.

Peter Stephenson
39521515c3 39867, tweaked: Use cast to unsigned char to test character. 
We want the unsigned variant to be <= 0x7f.  Use the normal STOUC()
macro and turn this into a single test.

9c68ef083b 39825: optimise mb_metastrlenend() for 7-bit character. 
As the shell relies intimately on US-ASCII as a subset we can
skip the multibyte functions if we are dealing with a complete
7-bit character.

d067ebcacd 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.

48cd1b6c3b 33894: boundary conditions in unmeta(), unmetafy() 
Check that we aren't running off the end of the string when converting the
next byte after a Meta byte.  This is just defensive programming in case
of bad metafied strings coming through from gettokstr(), some repairs
there are likely still needed.
