Portability patches

[Brian Koropoff]

Hi,

I've been working on a new build system (yeah, I know, *another* one)
that aims to be highly portable to various POSIX systems and light on
dependencies (in the spirit of autotools, though substantially less
insane).  Pure POSIX sh turned out to be robust enough for my project,
but the various UNIX systems I've ported it to lack anything with dash's
raw speed.  Naturally, I just ported dash to them as well.

Patch stack incoming.  I expect some of these might need further
explanation or revision before being accepted.

Regards,
Brian Koropoff

[PATCH 1/3] Port to Solaris

[Brian Koropoff]

- Solaris lacks paths.h and the various _PATH_* #defines.
  Check for them in configure.ac and fall back on the
  usual suspects when they are missing.

- Older Solaris lacks isblank(), and versions that have it
  use a macro.  Check for the declaration in configure.ac
  and fall back on a naive version when missing.

- Older Solaris does not support %jd (intmax_t) in format
  strings, but it does support %lld (long long), which is
  the same size on all architectures it supports.  Do
  a configure check for the sizes of both and prefer %lld
  when it is safe to do so.

- Older Solaris lacks stdint.h, but inttypes.h provides the
  same types and works on all platforms I've tried dash on,
  so just use it instead.

- Older Solaris doesn't like it when vsnprintf() is passed
  a NULL buffer (in violation of the POSIX spec, of course).
  Pass a 1-byte dummy buffer instead.

- Solaris lacks tempfile and mktemp programs.  Fall back on a
  "good-enough" custom function in mkbuiltins.

Pedantically, that's a regression for systems that do support %jd, and I
expect compilers to warn about it. If %jd is available, it must be used
for intmax_t, and not %lld, because that is for long long, not intmax_t.

What you can do is use PRIdMAX from <inttypes.h>, normally defined as
"jd". You can then define this to "lld" or "jd" if it is not defined.
I think this makes the code uglier (just like your change), but oh well.

<inttypes.h> is defined to be a superset of <stdint.h>, so that is ok.
It is also needed for the PRIdMAX suggestion above.

This is useful regardless as the <stdint.h> is redundant. The
<inttypes.h> is already needed here because of imaxdiv().

By the way, I wonder what the advantage of imaxdiv() above separate %
and / is. Compilers can detect the matching between a % b and a / b and
do it in one operation, and any use of imaxdiv() trips gcc's
-Waggregate-return.

I agree.  Brian, please update your patch accordingly.

Thanks!

It used to generate smaller code with gcc.  If gcc now knows how
to optimise it properly then I guess we can remove imaxdiv.

I just checked and gcc 4.4.5 still generates two divisions without
imaxdiv.  On the other hand gcc doesn't even inline imaxdiv.

Cheers,

I'll send an updated and rebased patch shortly.  Once we've agreed about
what to do with _LARGEFILE64_SOURCE in the HP-UX patch, I'll send a new
version of that as well.

[PATCH] Port to Solaris

[Brian Koropoff]

- Solaris lacks paths.h and the various _PATH_* #defines.
  Check for them in configure.ac and fall back on the
  usual suspects when they are missing.

- Older Solaris lacks isblank(), and versions that have it
  use a macro.  Check for the declaration in configure.ac
  and fall back on a naive version when missing.

- Older Solaris does not support %jd (intmax_t) in format
  strings, but it does support the PRIdMAX macro from inttypes.h.
  Do a configure check for PRIdMAX and use it in the code.
  If it doesn't exist, define it to "lld" when sizeof(long long)
  equals sizeof(intmax_t) as this is more likely to work on
  older systems.  Otherwise, use "jd" and hope for the best.

- Older Solaris lacks stdint.h, but inttypes.h provides the
  same types and works on all platforms I've tried dash on,
  so just use it instead.

- Older Solaris doesn't like it when vsnprintf() is passed
  a NULL buffer (in violation of the POSIX spec, of course).
  Pass a 1-byte dummy buffer instead.

- Solaris lacks tempfile and mktemp programs.  Fall back on a
  "good-enough" custom function in mkbuiltins.

Thanks for the patch.  I've made some minor updates before applying:

* Remove unnecessary config.h inclusions (already included on command
  line)
* Only check mktemp when tempfile is unavailable

Please take a look at the end result to see if I've messed anything
up.

Thanks,

commit bfcdc4969510997fe81debf52982641febfa1bdf
Author: Brian Koropoff <bkoropoff@gmail.com>
Date:   Tue Mar 15 15:35:14 2011 +0800

    [SHELL] Port to Solaris
    
    - Solaris lacks paths.h and the various _PATH_* #defines.
      Check for them in configure.ac and fall back on the
      usual suspects when they are missing.
    
    - Older Solaris lacks isblank(), and versions that have it
      use a macro.  Check for the declaration in configure.ac
      and fall back on a naive version when missing.
    
    - Older Solaris does not support %jd (intmax_t) in format
      strings, but it does support the PRIdMAX macro from inttypes.h.
      Do a configure check for PRIdMAX and use it in the code.
      If it doesn't exist, define it to "lld" when sizeof(long long)
      equals sizeof(intmax_t) as this is more likely to work on
      older systems.  Otherwise, use "jd" and hope for the best.
    
    - Older Solaris lacks stdint.h, but inttypes.h provides the
      same types and works on all platforms I've tried dash on,
      so just use it instead.
    
    - Older Solaris doesn't like it when vsnprintf() is passed
      a NULL buffer (in violation of the POSIX spec, of course).
      Pass a 1-byte dummy buffer instead.
    
    - Solaris lacks tempfile and mktemp programs.  Fall back on a
      "good-enough" custom function in mkbuiltins.

[PATCH 2/3] Port to AIX

[Brian Koropoff]

- AIX lacks a WCOREDUMP macro.  It's just used to
  append "(core dumped)" to the crash message, so
  #ifdef around it.

- For some reason, the nl program on AIX defaults
  to not printing line numbers ("-b n"), even though
  the spec says it should default to "-b t".
  Explicitly pass "-b a" for good measure in mkbuiltins.

[PATCH 3/3] Port to HP-UX

[Brian Koropoff]

- strtoimax and strtoumax are macros and not functions,
   so switch to using AC_CHECK_DECLS in configure.ac
   to find them.

 - HP-UX lacks strsignal() and sys_siglist.  Check for
   sys_siglist in configure.ac and #ifdef around it.

 - HP-UX's vsnprintf() completely violates the standard
   by returning -1 (and neglecting to set errno) if the
   buffer is not large enough rather than returning the
   size necessary.  Work around it by (yuck) reallocating
   a dynamic buffer until it succeeds so we can return
   the expected result.

 - HP-UX needs _LARGEFILE64_SOURCE to be defined for open64()
   and friends to be available.  This seems to be safe to
   define everywhere, so do so.

 - The nl program doesn't like spaces between flags and their
   arguments, so remove them in mkbuiltins.

Shouldn't this go into configure.ac? In fact, how can your patch
have any effect if configure.ac doesn't detect open64 in the
first place?

The rest looks OK.

Re: [PATCH 3/3] Port to HP-UX

[Brian Koropoff]

AC_CHECK_FUNC just checks that the symbol exists in libc, so it
succeeds.  _LARGEFILE64_SOURCE is necessary to get the system headers to
give you function prototypes, but it doesn't affect the configure test.

OK, please regenerate the patch against the head of my tree and
please move the macro definition from Makefile into config.h
through configure.ac.
