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)
issue spotted by carstenh, could have been a documentation ambiguity issue
(as -N was designed to read and return exactly n bytes), but this resolves
it in a way both backwards-compatible and user-pleasing
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).
separate the backslash+newline things out of the *.opt files,
logically not 100% clean, but better as it is not generated
content anyway (keeping the one-liners in there for now, even
though more consistent would be shifting them out as well)
• 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
getn() parses a decimal 32-bit integer, getint() a POSIX- or ksh-style based
integer with unsigned wraparound to 32 bit, then possible negation (so that,
for example, -0xFFFFFFFF continues to work)
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.
