tg 2d31aca859 more int→bool while trying to let ^D output CR+LF (which shan’t be, oh my…) 2012-05-04 21:15:34 +00:00
tg 5780bc5eb7 new MKSH_NO_CMDLINE_EDITING to disable command line editing in its entirety
mainly for the Plan 9 port though it may also help the WinAPI variant,
other porting efforts, as well as a new project I cannot say yet

tg 95a2c63096 • implement fcntl(2)-based advisory locking as an alternative iff flock(2)
is not found, from a suggestion by RT (LP: #912691)
• try harder (in a loop) to acquire a file lock if the locking mechanism
  documents EINTR is a possibility (fcntl always, flock on Linux not .Ox)
• use -std=c99 not -std=gnu99 if it must be at all

tg 87654270ab fix regression w.r.t. TTY and external programmes:
• release the TTY after the initial change_winsz()
• since we release it, we can skip initialising tty_state, too

tg c6b498d4fe meh, hit a regression again 2012-03-23 22:36:23 +00:00
tg 24e8a6996b always keep x_cols and x_lins valid; check once at start including tty init
if we find any, but not later; do not check on every read

⇒ allows changing COLUMNS and LINES (independent of each other, or both)
  for script shells by passing them in an environment setting, even if
  we get a tty; interactive shells still check before each line is read…

reported by the PLD guys, thanks

tg e8ea9954aa • Implement http://austingroupbugs.net/view.php?id=367 and align things
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)…

tg a796512040 • more comment and int→bool cleanup, add and improve some comments
• in interactive mode, always look up {LC_{ALL,CTYPE},LANG} environment
  variables if setlocale/nl_langinfo(CODESET) doesn’t suffice
• add the ability to call any builtin (some don't make sense or wouldn't
  work) directly by analysing argv[0]
• for direct builtin calls, the {LC_{ALL,CTYPE},LANG} environment
  variables determine utf8-mode, even if MKSH_ASSUME_UTF8 was set
• when called as builtin, echo behaves POSIXish
• add domainname as alias for true on MirBSD only, to be able to link it
• sync mksh Makefiles with Build.sh output
• adjust manpage wrt release plans
• link some things to mksh now that we have callable builtins:
  bin/echo bin/kill bin/pwd bin/sleep (exact matches)
  bin/test bin/[ (were scripts before)
  bin/domainname=usr/bin/true usr/bin/false (move to /bin/ now)
• drop linked utilities and, except for echo and kill, their manpages
• adjust instbin and link a few more there as well

tg 27dce9168a change behaviour of argument-less exit in traps to match SUSv4; Debian #599484 (original patch from Jonathan Nieder, thanks!) in a variant that appears to handle nested traps well 2010-11-01 17:29:05 +00:00
tg 667d792d6a • Address concerns of Chris Palmer from the Android security team
– possible integer overflows in memory allocation, mostly
    ‣ multiplication: all are checked now
    ‣ addition: reviewed them, most were “proven” or guessed to be
      “almost” impossible to run over (e.g. when we have a string
      whose length is taken it is assumed that the length will be
      more than only a few bytes below SIZE_MAX, since code and
      stack have to fit); some are checked now (e.g. when one of
      the summands is an off_t); most of the unchecked ones are
      annotated now
    ⇒ cost (MirBSD/i386 static): +76 .text
    ⇒ cost (Debian sid/i386): +779 .text  -4 .data
  – on Linux targets, setuid() setresuid() setresgid() can fail
    with EAGAIN; check for that and, if so, warn once and retry
    infinitely (other targets to be added later once we know that
    they are “insane”)
    ⇒ cost (Debian sid/i386): +192 .text (includes .rodata)
• setmode.c: Do overflow checking for realloc() too; switch back
  from calloc() to a checked malloc() for simplification while there
• define -DIN_MKSH and let setmode.c look a tad nicer while here

tg dcbfc48855 ┌──┤ apply Android patch from Jeff Hamilton:
│Don't alias 'stop' to 'kill -STOP'
│
│Android has already has a stop command used
│to stop the main runtime and the alias
│interferes with testing tools that expect
│stop to kill the runtime.
│
│Change-Id: I02b7efb9203dc39e97f63eb702a54ff79935b316

Although, this is closer to his first patchset and only takes
care of the alias, not the testsuite (which doesn’t run, at
least not out-of-the-box, nicely anyway) using #ifdef ANDROID.

We certainly want a more flexible testsuite…

tg 0c94277ccb To solve the incompatibility issues between mksh-current, old mksh versions
and vendor pdksh versions, re-introduce FPOSIX alongside FSH. The semantics
are now:
‣ set -o posix ⇒
  • disable brace expansion and FSH when triggered
  • use Debian Policy 10.4 compliant non-XSI “echo” builtin
  • do not keep file descriptors > 2 to ksh
‣ set -o sh ⇒
  • set automatically #ifdef MKSH_BINSHREDUCED
  • disable brace expansion and FPOSIX when triggered
  • use Debian Policy 10.4 compliant non-XSI “echo” builtin
  • do not keep file descriptors > 2 to ksh
  • trigger MKSH_MIDNIGHTBSD01ASH_COMPAT mode if compiled in
  • make “set -- $(getopt ab:c "$@")” construct work

Note that the set/getopt one used to behave POSIXly only with FSH or
FPOSIX (depending on the mksh version) set and Bourne-ish with it not
set, so this changes default mksh behaviour to POSIX!

tg eafe88aa74 • overhaul handling of special variables
• use a combination of the one-at-a-time hash and an LCG for handling
  the $RANDOM special if !HAVE_ARC4RANDOM instead of rand(3)/srand(3)
  and get rid of time(3) usage to reduce import footprint
• raise entropy state (mostly in the !HAVE_ARC4RANDOM case though…)
• simplify handling of the $RANDOM_SPECIAL generally
• tweak hash() to save a temp var for non-optimising compilers
• some int → mksh_ari_t and other type fixes
• general tweaking of code and comments

tg 33b9f8b666 * rename "set -o posix" (FPOSIX) to "set -o sh" (FSH) because it's not

tg a59d14b565 further optimise and simplify the handling of $RANDOM, reads and writes
to it are now either arc4random or rand/srand, but srand retains the old

arc4random(3), if not, we use rand(3) for $RANDOM reads; optimise special
variable handling too and fix a few consts and other minor things

abled language features), which can be set to 0 despite MKSH_SMALL being
defined to re-enable the Vi command line editing mode (which I wouldn't,
but fits into the general mastermind scheme)
2009-09-24 17:15:33 +00:00
tg 1a28786229 * shrink MKSH_SMALL even further by removing functionality like
some GNU bash extensions (suggested by cnuke@) and bind macros
* make the random cache more efficient (and the code potentially
  smaller, although we have a new implementation of the oaat hash
  function, alongside the old one, now) and pushb only if needed

tg 9531e12b36 merge the nameref code, using mksh standard scoping as discussed 2009-09-06 17:42:15 +00:00
tg 3a288c105f a couple of overnight, phone call and code/doku read ideas:
• we must not set the item pointer to NULL, since subsequent ktscan()
  would stop there and not find any later occurrences
  possible resolution strategies:
  ‣ still keep tablep; store a dummy value (either (void *)-1 or, probably
    more portable, &ktenter or something like that) as is-free marker
    ⇒ retains benefit of keeping count of actually used entries
    ⇒ see below for further discussion
  ‣ don't keep tablep; revert back to setting entry->flag = 0
    ⇒ need to ktwalk() or ktsort() for getting number of entries
    ⇒ most simple code
  ‣ same but with a twist: make ktscan() set pp to the first one with
    !(entry->flag & DEFINED)¹ so that it can subsequently be re-used,
    or, more accurate, free’d and the entry pointer re-used
    ⇒ less chance of texpand()ing when not needed
  ‣ similar (from kabelaffe@): in ktsearch(), move the one we DID find
    to the first unused one
    ⇒ doesn’t need tablep or something, but has the overall best
      memory use
    ⇒ more complicated ktscan(): needs to check pointer for NULL, for
      dummyval, then entry->flag
    ⇒ makes lookup more expensive
    ⇒ benefit: self-optimising hash tables
    ⇒ loss: still need ktwalk() or ktsort()
• when afree()ing in ktremove(), …
  ① need to take FINUSE into account
• Python-2.5.4/Objects/dictnotes.txt talks about cache lines
  ‣ linear backward scan is much worse than linear forward scan
    (even if we have to calculate the upper C-array bound)
  ‣ dereferencing the entry pointer in ktscan() is a penalty
• Python-2.5.4/Objects/dictobject.c has a lot of comments and
  a rather interesting collision resolution algorithm, which
  seems to de-cluster better than linear search at not much
  more cost
• clib and libobjfw have unusable (for looking-at-for-ideas)
  hash table implementations

this is a no-op change breaking ifdef-out-d code; the most likely
to happen is to switch to the following scheme:
• keep tablep in struct tbl
• use a magic pointer value for ktremove’d entries, deallocate
  the struct tbl as soon as possible – if not FINUSE, immediately
  inside ktremove()
  ‣ memory gain, despite needing to have tablep around
• nuke ktdelete, so that all ops go through kt{enter,remove}
  ‣ gains us accurate fill information
  ‣ speed gain: ktscan() needs no longer dereference removed entries
  ‣ memory (ktsort) and speed (ktwalk) gain: removed entries are now
    ignored right from the beginning, so tstate->left and the size
    of the sorted array are accurate
  ‣ removed entries no longer can cause texpand() to be invoked
⇒ this does not give us self-optimising tables, but a speed and
  memory benefit plus, probably, simplicity of code; we accurately
  know how many non-deleted entries are in a keytab so we can cal-
  culate if we need to expand, how much space ktsort() is going to
  need, and, for when indexed arrays will be converted to use key-
  tabs instead of singly linked linear lists, ${#foo[*]} is fast
  (although ${!foo[*]}² and ${foo[*]}³ will need some tweaking and
  may run a little less quickly)
• shuffle code around, so that things like search/scan and garbage
  collection can be re-used
• use Python’s collision resolution algorithm ipv linear search

② the list of keys needs to be sorted, at least for indexed arrays⁴
③ this needs to be sorted by keys, at least for indexed arrays⁴
④ … but this is a nice-to-have for associative arrays⁵ as well
⑤ which we however do not have
2009-08-29 11:26:44 +00:00
tg 9b8d4023fa … but since I liked the bonus of having the hval stored so much, merge
it with the array index; var.c says that
│ 1244         /* The table entry is always [0] */
so that we can have a special flag and a union which stores hval for
the table index, the array index otherwise (coïncidentally *hint hint*
they have the same size)
2009-08-28 21:01:27 +00:00
tg bb7a720a00 for now, until we really use kt*() otherwise, ifdef out tablep/hval 2009-08-28 20:38:43 +00:00
tg 4ccdfc8508 much better solution: save tablep and hash value¹ in the struct tbl entry
① also saves time during texpand :D

XXX this doesn’t work well with the current indexed-array implementation
2009-08-28 20:30:59 +00:00
tg 7240c843ce this is a rather stupid diff: give ktsearch/ktenter the capability to
return information needed to do a real ktremove instead of the pseudo
ktdelete operation which merely unsets the DEFINED flag to mark it as
eligible for texpand garbage collection (even worse, !DEFINED entries

  for specific OSes, bad, instead of using mirtoconf checks proper) and

pass "xerrok" status across the execution call stack to more closely
match what both POSIX and [18]ksh.1 already describe in regards to set
-e/errexit's behavior in determining when to exit from nonzero return
values.

specifically, the truth values tested as operands to &&' and ||', as
well as the resulting compound expression itself, along with the truth
value resulting from a negated command (i.e. a pipeline prefixed !'),
should not make the shell exit when -e is in effect.

  ‣ other than that: working fine
  ‣ -YBSD (default) and -YSYSTEM_FIVE don’t work, just -YPOSIX, somehow

  ‣ it seems to have ucode, but man is not installed
• new mirtoconf check: mkstemp(3)
• if !HAVE_MKSTEMP (Ultrix), use tempnam(3)
• only use printf(1) if it exists (it doesn’t on Ultrix)
• a few more signals
• add S_ISLNK if the OS doesn’t define it
• add strcasecmp(3) proto for Ultrix (it _is_ in <portability.h>, but
  only for -YBSD I think)
• fgrep(1) on Ultrix doesn’t do “-e ① -e ②”

tg 0989f7da67 Fix for Coverity CID#2: false bug, but still a problem.
Analysis:
internal_errorf(int, fmt, ...) was only a __dead function if the int argument
was non-0, which the Prevent probably was unable to follow. Change all uses of
internal_errorf(0, fmt, ...) to internal_warningf(fmt, ...); change the pro-
totype of internal_errorf() to internal_errorf(fmt, ...) and all remaining
uses remove the non-0 int argument; add __dead to internal_errorf() proto;
flesh out guts of internal_errorf() and internal_warningf() into a new local
function for optimisation purposes.

Some whitespace cleanup and dead code removal (return after internal_errorf(1))

tg 273ca89019 * check.t: add new regression test "typeset-padding-1" according to TFM
* edit.c: remove debug stuff again; next time better use shl.c functions ;)
* sh.h: add format attributes to a few shf functions
* histrap.c, var.c: fix format string mistakes
* main.c, sh.h: error_prefix and warningf take bool not int
* misc.c: make chvt() stuff use shf_* functions
* misc.c: rewrite the TIOCSTTY stuff to be better integrated in mksh,
  since it originally was an external patch
* misc.c: chvt() no longer fails if e.g. chown fails due to e.g. R/O / fs
* var.c: fix typeset padding for right-justified zero-filled

tg 4fac7ec24b * remove redundancy
* integrate compat.h, version.h into sh.h (dependency trick didn't work anyway)
* mention #ksh in mksh(1) since the founder (twkm) said it's on topic too
  (don't remove mention of #mksh despite it's usually empty because of control)

tg daa40b4e45 this is mksh R27, tested on
* MirOS HEAD (i386, gcc 3.4)
* Debian GNU/Linux 3.1 (i386, gcc 3.3)
* Interix 3.5 (i386, gcc 3.3) - perl too old for regression tests
* GNU/Cygwin 2006-03-* (i386, gcc 3.4) - no perl installed
* Solaris 8 (sparc64, gcc 3.4)

no testing been done on
* Mac
* other BSDs
* gcc 4.1.1
* Solaris 10
because I asked for community feedback but...
2006-05-26 23:36:19 +00:00

tg 7672b9b346 apply some fixes from OpenBSD and don't apply some others
but sync RCS IDs for easier future adaption:
* Simplify savefd() by removing the "noclose" flag and make noclose
  behavior the default. Almost all uses of savefd() are followed
  by an implicit or explicit close.
* fix typos
* might as well make ksh_getopt() match real getopt(), ie. get rid of that
  stupid EOF concept that was never true. adobriyan@gmail
* use SEEK_* for lseek()
* fix lint comments, no functional changes
* remove excessive optimization; from adobriyan@gmail
* only santa checks things twice; from adobriyan@gmail
* Interpret zero-filled numbers as decimal; PR 4213; from Alexey Dobriyan

tg c4ef5b801a New feature: read ~/.mkshrc during startup, after the profiles
have been read, for non-priviledgued shells only. If $ENV is
set, ~/.mkshrc is ignored (even if the file pointed to by $ENV
does not exist in the first place).
Feature requested by Jari Aalto for portable mksh because some
operating systems' vendors do not allow touching the profile.

Initial diff and manual page addition by Jari Aalto <jari.aalto@cante.net>
Code changes and manual page correctness by me.
2006-05-08 11:42:36 +00:00
tg 3f2912d717 * update to mksh R26c

2006-01-30 12:37:24 +00:00
tg eb33e02f8e this can be released as mksh-R26c, works on Solaris, Interix (whose Perl
is too old for the testsuite), Debian and of course MirOS

tg 2f9687c58a follow OpenBSD and add mknod as mksh builtin (mknod <file> p acts as mkfifo)
but write a good chunk of that code myself (better structured, better error
handling, more gotos, less function calls, int -> bool)

passes all tests on mirbsd; this will become mksh R25 once tested on other
supported OSes
