Closes: LP#1580348
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
‣ 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
This enables to convert CR+LF to LF when reading, but disables to
convert LF to CR+LF when writing.
Instead, however, CR+LF are not passed into mksh as is.
OS/2 kLIBC has only a declaration of getrusage() without implementation.
Due to this, definition of getrusage() stuffs causes compilation to fail.
-----
In file included from lalloc.c:21:
sh.h:379: error: conflicting types for `getrusage'
f:/lang/gcc/usr/include/sys/resource.h:168: error: previous declaration of `getrusage'
-----
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)
so we mitigate a bit (in var.c mostly) and tweak another type already, and
add some checks (mksh_{,u}ari_t must fit into {,unsigned }long) and print
line numbers with %lu already
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.
bug initially found by Pawel Wylecial (LP#1440685)
additional bug found and suggested fix by enh (elliott hughes)
This commit also renames struct ioword.flag to ioflag to disambiguate
it from other members named “flag”, changes it to an unsigned type,
and packs ioflag and unit into shorts each, to make the struct smaller
(aligned even: 16 bytes on 32-bit systems) and reviews some of the
code involved in fd handling, though there wasn’t much to be found.
‣ : → \:
‣ 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
• all: bump version to R50-current; add more comments; whitespace
• all: remove all mkssert(); we’ll do full re-runs of scan-build and,
hopefully, Coverity Scan/Prevent
• check.t: fix a testcase (sed could exit false, but we don’t care)
• eval.c: fix tilde_ok data type (only unsigned may shl constantly)
• exec.c: fix shebang buf array accesses to always go via uint8_t *
