ca17798533 this is bash compatibility week, and by suggestion of actual users,
namely Dr. Robert “Pfeffer” Arnold (in this case, in FreeWRT), make
a half-completed attempt at implementing ${foo:2:3} substring evals
(of course, negatives can't work right now and that the numbers are
in face expressions is something I only read later too – this is to
be revisited later, but it's already late)

don't depend on this behaviour yet though

if someone wants to add more regression tests, feel free to…

e596de4759 make sure that “integer” and “local” are defined even in FPOSIX mode, which
is a compromise anyway; these lunox people will have to live with that, too
many existing korn shell alike scripts depend on it even if not on the full
korn shell syntax availability (note: this doesn't mean using these in some
script with #!/bin/sh is ok)

10b48d1f92 on Linux 2.0, <sys/sysmacros.h> defines makedev(), but on Solaris, both it

1e93f97b8c compile warning-free on SUNpro (regression test suite pass) for MirBSD 2007-06-04 21:33:28 +00:00
tg
6e1bfd6e4b When compiling native MirOS BSD binaries with SUNpro 12 (don't look like a
car only slower, yes this is possible, and the resulting binary passes the
testsuite just fine), the definition of __RCSID() in <sys/cdefs.h> expands
to something with __attribute__((used)), which triggers a warning, because
__attribute__ in general is supported but the used attribute isn't. Thusly
always use our own strings and get rid of the MULTI_RCSID test (introduced
because __RCSID() on Darwin is inferiour).

Maybe we should fix <sys/cdefs.h> too? #ifdef __SUNPRO_C helps here.

2beb60ebf3 for R30, don't check for confstr() declaration any more

a84655e3e0 fix Coverity CID #8, #9
it's wrong to use strchr(s, 0) to look for the NUL byte, because in some
environments it apparently might return NULL

use new macro strnul = s+strlen(s) instead (not side-effect safe tho)
2007-05-13 19:14:05 +00:00
tg
e392983af7 Possible fix for Coverity CID#7:
convert options() prototype to unsigned (size_t, in fact), and make an
explicitly casted (size_t)-1 the error return code, modelled after what
is often used in Unix libraries
2007-05-13 18:33:29 +00:00
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))

1a0b51b697 • arc4random, arc4random_push: use our own protos to check
XXX u_int32_t is not ISO C99, but seems to work well enough
  XXX if it fails anywhere, we'll see in the build logs
  XXX apple doesn't have the standard uint32_t and API doesn't specify it
• sys_siglist_defn: rename to sys_siglist_decl as we're really checking
  for the declaration in the headers; change wording to “check if … does
  not need to be declared” since we don't need to declare if we don't use
• scan for arc4random, arc4random_push, confstr declarations too

2785ce3de4 • (re)implement shebang execution file parsing; this makes the “and which
do not start with a "#!shell" sequence” part of mksh(1) true again; this
  was probably lost in mksh R21 or so when I decided/saw that our kernel
  always parses shebang lines (code written myself, not taken from pdksh
  again or MirBSD kernel, but verified against both)

subsequent line, or within a line, etc.); regression test for it

2f15a11c55 Clean up the signal mess, saves 172 Bytes:
* 'sigseen' in Build.sh goes away
* Signal name existence is checked in this order:
  have our own¹ -> sys_signame[] -> _sys_signame[] -> build our own²
* Signal description existence is checked in this order:
  sys_siglist[] -> _sys_siglist[] -> strsignal() -> NULL³
¹ Predefined list of items, for operating systems where we
  cannot build² them, i.e. Plan 9 and Minix 3 (e.g. no $CPP -dD)
² The usual cpp(1) stuff
³ Changed later, see below
* Make $CPP test dependent on $NEED_MKSH_SIGNAME (others can
  be added here, this is not absolute)
* Make signal name list generation² dependent on $NEED_MKSH_SIGNAME
* Fix check if the generation worked
* Guarantee that sigtraps[*].name and sigtraps[*].mess are valid
  C strings; this makes the code shorter *and* removes a few pos-
  sible nil pointer dereferences
* Embed autoconf'd usages of sys_sig* / strsignal / mksh_sigpairs
  into inittraps()
* Check for each signal 0<=i<=NSIG that
  name is not NULL or "" -> replace with ("%d", i)
  mess is not NULL or "" -> replace with ("Signal %d", i)
  name does not start (case-insensitive) with "SIG" -> name += 3
* In gettrap(), fix check if signal name starts, case-sensitive
  or case-insensitive, depending on need, with "SIG" (bug from millert@)

* Build.sh: ac_test[n]() are documented
* Build.sh: ac_test[n]() can have negative prereqs as well now

2342fa1242 don't use setreuid(2) etc. stuff, like OpenBSD

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
