• while here, reformat 'struct tbl' comment-wise and placement-wise
and drop the Tflag typedef
• while here, write regression test for the "global" built-in, which
does what typeset is supposed to do except that it doubles as "local"
• IBM XL C: display version better (tested on V7.0 by cnuke@)
• do not 'IFS=: read nr name', Cygwin 1.7 dash fails it
• disable cd-pe, glob-range-3 on Cygwin (the former cannot
succeed because the mv fails, the latter fails from 1.7 on)
• mark heredoc-tmpfile-8 as need-pass: no
• apply __attribute__ only to a function prototype, not to
the body (even if static), since xlC fails that
• bump version to R40 (beta)
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
• don’t leak memory parsing possible I/O redirection tokens
• get rid of volatile by using more const (also helps codegen, methinks)
• support empty here document markers (mksh extension)
• pimp the manpage
• ensure that bool/true/false are cpp macros, overriding any pre-defined
• document the requirement that tobool(x) must map any-type 'x' into bool
• document the requirement that a bool must only be true or false, and
that it (tobool() rather) must have an identity mapping to 'short'
• possibly fix ksh_func for/and fpFUNCTf – maybe spotted by cnuke@
a bit more with POSIX and the other shells
I considered http://austingroupbugs.net/view.php?id=253 but the use
of bi_errorf() is interesting, especially as it’s often enough a
noreturn function, and funnily enough, 'cd -P /foo' returns 0 while
'chdir -P /foo' fails (so idk where to put -e)…
⇒ 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
and switches to the TARGET_OS=Linux
• introduce android as regression test suite category
• add an android specific standard alias
• clean up redundant ‘-o sh’ arg in a few checks
UTF-8 BOM instead (UTFMODE has a separate value now for activated
during BOM skipping)
• parsing a COMSUB now skips UTF-8 BOM, too, but only temporarily
(token stream, lexer output / parser input), EOS terminated, let
SASPAREN use the same lexing as SBASE (e.g. COMSUB recursively)
• make wdstrip recursive
• fix processing of COMSUB in wdstrip
⇒ pass comsub-1 test
• expose another debugging function
• use shf_putc (macro), shf_putchar (function) ipv tputc
• replace shf_putchar(x,y) calls for side-effect-less x with shf_putc
• plug another bug in the tree code – '\' → "\\" (backslashes must be
escaped inside double quotes, too)
• adjust testsuite (and, I _had_ wondered…)
EOF) # works again now, plugging a regression
• rewrite the here document parsing code to be *much* more efficient
(and a bit more readable too!) using goto, while here (no kidding)
① currently: ((cond) ? true : false) but (!!(cond)) and casting to bool,
the latter only if stdbool.h, would also work – which performs best on
(and across) all supported systems?
instead, but the parser for the so-called “backticks” (U+0060) still emits
plaintext COMSUB wdstrings, and the evaluation code emits plaintext if the
code is not run (‘-n’ option), so it’s not worth the effort and memory ma-
nagement issues, even though it _would_ optimise the most common case…
Bump version numbers, sync regression tests; add one testcase from the old
webpages too. Sync manpage, this now works, but keep the workaround in, as
“portability issue” with slightly changed wording.
Also, /bin/sleep must be used in one manpage example if sleep is built in.
• functions called by mksh’s grouping memory allocator
• functions called by mksh code itself
the latter may be changed to call the internal grouping allocator,
if a porter so desires (but if this were recommended, the code in
question would already do so, so…)
