tg b50b43e3bf get rid of "U getenv" 2009-09-26 01:08:27 +00:00
tg 1dfb13b603 change undef/def MKSH_NOVI into 0/1 MKSH_S_NOVI flag (with more to come:
MKSH_S_EDIT for small (Emacs) editing mode, MKSH_S_FEAT for all the dis-
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
  (i.e. state has changed or user has set $RANDOM, but not onfork)
2009-09-23 18:04:58 +00:00
tg 588921333e more of this:
• shell flags are now handled in one single place (sh_flags.h)
• sync comments (between enum and array) and manpage with reality
• FMONITOR is now no longer needed for Hartz IV shells
2009-09-20 16:40:58 +00:00
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
are still counted)
2009-08-28 19:57:43 +00:00
tg ca1f967a45 • use Jenkins’ one-at-a-time hash for mksh keytabs, as it has
much better avalanche and no known funnels
• improve comments
• fix some types (uint32_t for hash, size_t for sizes)
• optimise ktsort()

no functional change, I think

tg 0e1266ef90 While mksh R39 builds fine on MirOS #7s8E on my trusty sparc, pgcc 2.95.3

2009-08-08 13:08:53 +00:00
tg 758dc5c6fe * improve CPPFLAGS vs #define handling again: do not touch CPPFLAGS from
Build.sh but use 'if defined(PRECOND) && !defined(TOBEDEFINED)'if possible
* for all of the source code, drop annotations "imake style" (if we check
  for specific OSes, bad, instead of using mirtoconf checks proper) and
  "conditions correct?" (if I'm not entirely sure if that #if catches all
  cases and no false positives) where I can see it by grepping immediately
* bump mksh patchlevel
* refresh Makefiles

tg da5dc48cd0 implement an extension that an interactive mode input line, when

tg 361dee04f3 laffer1 agreed they will need -DMKSH_MIDNIGHTBSD01ASH_COMPAT in the

2009-05-16 21:00:52 +00:00
tg b6ce748064 • remove “#if 0” and “#ifdef notdef” style old debugging code

tg b145ca5c9f • sync distrib/special/mksh/Makefile with bin/mksh/Build.sh and
fix the regression test’s results while here, which have been
  broken since cid 10049D9BE5254CE65B8
• get rid of separate copyright file which was intended for De-
  bian; track down commits in all files of oksh-mirbsd and mksh

tg 8cc7fdb834 "evil" workaround to the alignment issues: embed an ALLOC_ITEM into

tg b20f49adae patch from oksh (except manpage, I'll merge that later):
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.

issue reported by matthieu.

tg 31d1499219 * back out almost all of the memory allocator related changes, as aalloc
was hard to type and hard to fix, galloc is also hard to fix, and some

2008-10-28 14:32:43 +00:00
tg 0c2de1902c • change mksh to only then behave more POSuXish when called as /bin/sh or

tg 9be489ea90 use less stack storage, prefer .bss storage (saves us a memset() call)
and .data instead of another initialisation; this was prompted by a bug
in scan-build (the value can never be NULL, but it doesn’t realise it),
although this doesn’t fix it, but less stack usage is always good

tg 6be5205b36 mksh:

* bring back PGRP as base-10 integer to the process group via getpgrp(2)
* initialise USER_ID as base-10 integer to the effective user id as retrieved
  from geteuid(2) = $(id -u)
* use $USER_ID in dot.mkshrc instead of spawning an id(1) process
  -> dot.mkshrc,v 1.34 now requires mksh R34
* convert more int to bool where appropriate
* remove dead code - getpgrp(2) cannot fail
* sync manual page to reality
* bump to mksh R34(beta) - feature freeze

XXX check if our_pgrp in jobs.c is still really needed, the setpgid call
XXX probably just makes us our own pgrp leader, and we might have to use
XXX and update kshpgrp accordingly - need feedback/help here but I think
XXX this simplification should be possible if I grok the code correctly.

• 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

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 1692a6da66 ignore the UTF-8 Byte Order Mark at the beginning of the input (via a file
given to execute, standard input (interactive or not), via -c command line
argument, or after “eval”, but not for $(…) comsubs, at the beginning of a
subsequent line, or within a line, etc.); regression test for it

idea during my “week off” (despite the pain), bsiegert@ thinks it's good –
and utf-8 capable tools ought to be able to do this anyway

tg 83c2ee87f4 • remove strcasestr.c, use home-grown implementation¹, call it stricmp,
and have it return an API-correct const char *
• enhance and stylify comments
• a little KNF and simplifications
• #ifdef DEBUG: replace strchr and strstr with ucstrchr and ucstrstr
  that take and return a non-const char *, and fix the violations
• new cstrchr, cstrstr (take and give const char *)
• new vstrchr, vstrstr (take const or not, give boolean value)
• new afreechk(x) = afreechv(x,x) = if (x1) afree(x2, ATEMP)
• new ksh_isdash(str) = (str != NULL) && !strcmp(str, "-")
• replace the only use of strrchr with inlined code to shrink
• minor man page fixes
• Minix 3 signames are autogenerated with gcc
• rename strlfun.c to strlcpy.c since we don't do strlcat(3) anyway,
  only strlcpy(3), and shorten it
• dot.mkshrc: move MKSH=… down to the export line
  to not disturb the PS1 visual impression ☺
• dot.mkshrc: Lstripcom(): optimise
• bump version

¹) side effect from creating API-correct cstrchr, cstrstr, etc.
   uses goto so it must be better ☻

no warnings at autoconf time left either; will take care of these two later

builtins to have their argv[] be const strings, and go through strict type
and qualifier checking again. this'll further improve stability.

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.

tg cd7b8bd79b Add mirbsdksh R21, which was developed in a temporary external CVS repo-
sitory whose ChangeLog follows. mksh R21 is licenced under the MirOS li-
cence, shown in "sh.h", and a two-clause UCB-style licence by Marc Espie
as shown in "alloc.c".

This executable is a fair bit smaller and shorter than our /bin/ksh that
it is designed to eventually replace (as /bin/sh hardlink), with the old
/bin/ksh to completely vanish. It is still in beta testing though, and I
don't think it will compile on other operating systems.

mksh R21 is a completely new port, bringing together the OpenBSD-current
/bin/ksh, the MirOS-current /bin/ksh and the older mksh R20 (which still
was portable, ocvs-based).
