introduced by the utf_skipcols()-related fixes, more
specifically the check for combining multibyte characters
past end of given width (bogus mixed-up semantics we have here)
by reïntroducing the NUL byte from commitid 1005474EE1E4024A4E4
• trailing combining character
• ${!#} and friends
the warning is: pid_t is signed (so PIDs could be negative) and may be
rather long, in some cases even longer than a C “long”; we’ll need to
handle this by adding checks (sizeof pid_t=gid_t, sizeof pid_t must be
either mksh_ari_t or u_short) and code (always print $$/$! as unsigned,
set unsigned attribute on $BASHPID and friends)
‣ I was convinced by several that more magic is never the solution
• fix a comment: function cat already had precedence
• change cat loader to look for existence, FPATH included, before
ditching the builtin; note that in manpage
plus plugs an ancient memory leak (hist_execute afree’s its arg now);
also partial revert of commitid 78014291f06497b3 as COMPLEX_HISTORY handles
multi-line commands correctly now (r1.4, 2005-05-23)
in commitid 1004D8283F068C41C3C was bogus; it fixed Jb_boin’s issue
but izabers’s 「var=foo; echo "${var/*/x}"」 was broken; in fact we
only want to not do the looping for // if the pattern matches much.
Also, fix a spelling mistake in the manpage and change some wording
to also work with associative arrays (in the future; no change).
• support NSIG_MAX from http://austingroupbugs.net/view.php?id=741
and make a TODO for later to use sysconf(_SC_NSIG) at runtime
• bounds-check signals (e.g. no smaller than 1, but smaller than NSIG)
• align trap errorlevel with other shells
• make trap match what’s in POSIX and fixup the manpage
• refactor some code related to signals
• hide from kill builtin both EXIT and ERR pseudo-signals
• ord() new, From: Daniel Richard G. <skunk@iSKUNK.ORG>
‣ used in some places
• (c - '0') → ksh_numdig(c) # may take *x++ argument
• (c - 'A') → ksh_numuc(c) # may NOT take *x+= argument
‣ idem for ksh_numlc(c) and 'a'
‣ these need changing for EBCDIC
‣ add testsuite for this
• use macros more, they exist already often
• use digits_lc[foo] instead of ('0' + foo), especially for letters
• caught another ksh_eq case…
• also caught a maybe-UB overflow check, but we don’t have TIME_T_MAX ☹
GNU C11 (Debian 20150413-1) version 5.0.1 20150413 (prerelease) [gcc-5-branch revision 222050] (x86_64-linux-gnu)
including ASan (testsuite) and Valgrind (short)
for mksh but not lksh; bump to R51-alpha.
While here, tweak build scripts a bit, fixup MirBSD-specific Makefile
things, remove part of a comment that’s uninteresting.
‣ : → \:
‣ alias → \alias
⇒ except in some internally used cases, where we use \builtin alias
‣ command . → \command .
• protect Korn Shell builtins from aliases and functions, e.g:
‣ typeset → \builtin typeset
⇒ also unravels the “local” alias used
‣ print → \builtin print
• protect internally-used things from aliases
‣ “let]” is not a valid function name
‣ “set” is POSIX so we don’t expect anyone to override it in a function
• use “command -v” instead of “whence -p” (“which”) in most
places; thanks izabera from #ed on IRC for pointing out
that “command -v” is POSIX – except, “whence -p” a̲l̲w̲a̲y̲s̲ looks
for an executable and shows its full pathname; “command -v”
also resolves to aliases, functions and builtins, so only use
it where it makes any sense (both never output to stderr)
• make most of dot.mkshrc work in the face of such aliases
‣ “ulimit -c” is used; this is not POSIX, and not portable;
maybe we should make ulimit accept-and-ignore the most
common limits even if the OS doesn’t use them?
• update list of builtin aliases in the manpage
