tg f463d9da76 • revert the cat hack for realpath and rename
‣ 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
2015-07-06 17:48:37 +00:00

tg cad9bc86d3 Implement the “FKSH functions have local scope for shell options” feature

things, remove part of a comment that’s uninteresting.

tg e1cda74d04 SECURITY: fix integer overflows related to file descriptor parsing
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.

tg 07898d8a45 only lksh now implies unalias for a POSIX function definition (used e.g. in Debian sysvinit scripts that use a “stop” function) 2015-03-20 23:37:55 +00:00
tg 73082b9292 • fixup here document expansion (regression wrt. pdksh 5.2.14)
• adjust testsuite (and write tons of new tests) after today’s commits
2015-02-19 22:26:50 +00:00
tg 1248a0a521 basically unbreak use of $*/$@ in here documents
a bit funny:
with NUL IFS, $* behaves like dash ('ab') and $@ like bash/ksh93 ('a b')

with WS or NWS IFS, all shells behave alike though
2015-02-19 22:00:03 +00:00
tg ab683420df fix use of $*/$@ in scalar context in [[ … ]] and case; spotted by Stéphane Chazelas 2015-02-19 21:58:19 +00:00
tg f6f49a119b add getopts for exec (unbreaks “exec -- /bin/ls”) and steal -a and -c from ksh93 2015-02-06 10:56:49 +00:00
tg b94b2e363a stop (ab)using the OS symbolic constant EOF, always use -1; plus misc fixes 2015-02-06 10:09:07 +00:00

tg 2f26836ed1 fix shebang/magic decoding 2014-11-25 22:46:58 +00:00
tg 2f52b993a1 • Build.sh: fix NSIG detection for gcc-snapshot
• 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 *

tg 44dc99cb35 first cut at LP#1381993 (probably incomplete) plus test coverage

tg 996e05548a POSIX says “command” loses SPEC_BI and means it too
reported by ormaaj, who even asked on the austin ML
http://thread.gmane.org/gmane.comp.standards.posix.austin.general/9907/focus=9931
clarified by jilles; also make errorlevels match ksh93

tg 73edeaa8ec fix “set -o pipefail” w/o PIPESTATUS, and PIPESTATUS inside COMSUBs and other sequences 2014-06-10 22:17:10 +00:00
tg 033e1f4b9e fix LP#1277691 (“nameref RHS not syntax checked”) and the inability to
use errorf() while nameref states were being changed (by almost completely
eliminating the global variable) and the readonly first array variable
bypass (typo/refactoro); also, whitespace, one int → bool, and add a
comment wrt. the parser rewrite talked about with igli during a fever ;)

tg c1c0b997fe make the code to exec simple commands also available for mksh_small 2014-01-11 16:26:28 +00:00
tg 89e774fd7e • fix ${12345678901234567890} segfault (OOB access / integer overflow)
‣ not like oksh did, but using mksh’s built-in features
• handle suggested __pure additions
• revert cid 1004F7F096867C83CF0
  ‣ always use our wcwidth code
  ‣ only use our strlcpy code if none found
• fix a couple of gcc-snapshot and clang/scan-build warnings
• mksh R49~rc1

tg ead77623d3 Fix most “set -x” problems (LP#1179287)
• “set -x” manually (cmdline too) snapshots fd#2 now
• “set -o inherit-xtrace” introduced; default still enabled
• reverted iodup printing to pre-R45 behaviour
• made Flag(FXTRACE) a proper state machine
2013-07-21 18:47:24 +00:00
tg bd795a83ae partial merge and full RCS ID sync with oksh
merged:
• new regression tests
• check.pl (tests/th) better tmpfile handling
• exec.c 1.50: POSIX specifies that for an AND/OR list,
  only the last command's exit status matters for "set -e"
• ksh.1 1.147: document the above
• eval.c 1.39: “Make $(< /nonexistent) have the same behaviour
  as $(cat /nonexistent) wrt. errors (do not unwind and do not
  treat this as fatal if set -e is used).”
  ‣ additionally make shf_open() return errno and actually show
    the error message from the system
• regression-39 test: remove the “maybe” marker
  ‣ but decide on correct POSIX behaviour

already been fixed in mksh:
• check.pl (tests/th) exit 1 if tests fail

not merged:
• main.c 1.52: run traps in unwind() before exiting;
  I’m pretty sure this is already working as-should in mksh
• eval.c 1.38: “Commands executed via `foo` or $( bar ) should
  not inherit "set -e" status.” As discussed in IRC, this is
  just plainly WRONG.

tg bb4083d649 use ‘z’ shf printf modifier for out-of-memory message, now that we have it 2013-06-03 22:28:33 +00:00
tg 8256f266ff fix a number of warnings and other issues:
• sig_t detection was a bit insane, it is a function-pointer type after all
• fix uninitialised variable in c_select which led to mistakenly accepting
  invalid (nōn-numeric) input and acting, randomly, upon it
• keep SIGCHLD blocked in child after forking longer, for job list manip
• block SIGCHLD ifdef DEBUG_LEAKS to not run job foo during/after afreeall
• fix annoying ISO C90 vs. C99 (un)signed constant warning
2013-06-02 03:09:17 +00:00
tg deb4a3bf20 Oh well… this looks well, is done done, and gcc-snapshot doesn’t complain:
• correct order of built-in commands; use POSIX special versus “all others”
  plus “keeps assignments” as distinction, no longer play POSIX regular vs.
  others game; sync manpage
• fix LP#1156707: map (( internally to “let]” which is no valid function
  name and so can’t be overridden but is unlikely to be used otherwhere
  and not strictly permitted (by POSIX) anyway
• we do not need -Wno-overflow any more, either
• bump to R45

tg b6f4617dee oops… pasto… restored the wrong backup code…
(I had one that didn’t revert cid 100514E4F1D5C90862C in check.t first…)
