that get used, plus one for the realpath-1 regression test; also make
sys_siglist_decl detection nicer and poison strerror() with non-const
return value ifdef DEBUG, make it always const
into AT&T ksh93 (that we still must use octal, in this day and age,
because dgk’s \x is broken… tss…)
not round-trip, as ksh93 doesn’t encode hi-bit7 or \v, but safe
if we find any, but not later; do not check on every read
⇒ allows changing COLUMNS and LINES (independent of each other, or both)
for script shells by passing them in an environment setting, even if
we get a tty; interactive shells still check before each line is read…
reported by the PLD guys, thanks
Testsuite:
• add new need-pass: {yes|no} attribute, default yes
• exit with 1 if a need-pass test failed unexpectedly
idea by Kacper Kornet <draenog@pld-linux.org>
• mark utf8bom-2 as need-pass: no
Infrstructure:
• add housekeeping function for making a tty raw
• switch functions with unused results to void
• struct op: u.charflag contains last char of ;; in TPAT
• var.c:arraysearch is now a global function
Language:
• add ;& (fall through) and ;| (examine next) delimiters
in addition to ;; (end case) as zsh extensions, because
POSIX standardised on ;& already
• add -A (read into array), -N (read exactly n bytes),
-n (read up to n bytes), -t (timeout) flags for read
from ksh93
• allow read -N -1 or -n -1 to slurp the entire input
• add -a (read into array the input characters) extension
specific to mksh to read, idea by David Korn
• add -e (exit with error if PWD was not set correctly
after a physical cd) to cd builtin, mandated by next
POSIX, and change error codes accordingly
Rewrites:
• full rewrite of read builtin and its manpage section
• add regression tetss for most of the new functionality
• duplicate hexdump demo tests for use of read -a
• use read -raN-1 in dot.mkshrc to get NUL safe base64,
DJB cdb hash and Jenkins one-at-a-time hash functions
⇒ consider merging simplify_path()
• move funcs.c:c_cd() to misc.c
• make misc.c:make_path() static, c_cd() is its only user
⇒ mark as obsolete
• tweak misc.c:set_current_wd() to drop ksh_get_wd() argument
should be no code change, but the entire path stuff is a mess…
so expect actual implementation changes or even rewrites shortly
to catch several very slow cases (especially “*@(*foo)” busy-loops
– spotted by Jb_boin as usual these days ☺) by converting all @(…)
with one case to drop the enclosing MAGIC(…), and in a second pass
collapsing adjacent asterisk (‘*’) wildcards
