[PATCH 0/8] enhancing builds on Solaris

[PATCH 0/8] enhancing builds on Solaris

[Brandon Casey]

From: Brandon Casey <drafnel@gmail.com>

Junio,

Here is a re-roll of the work on Solaris which integrates the ideas from you
and Jeff.  This should replace bc/solaris in pu.

This should allow compiling on Solaris with or without a c99 compiler,
GCC or SUNWspro.

Solaris 7 should be able to compile when using GCC and bash.

From: Brandon Casey <drafnel@gmail.com>

We can avoid a GNU dependency by using /usr/ucb/install.

[PATCH 2/8] Makefile: add NEEDS_RESOLV to optionally add -lresolv to compile arguments

[Brandon Casey]

From: Brandon Casey <drafnel@gmail.com>

This library is required on Solaris when compiling with NO_IPV6 since
hstrerror resides in libresolv.  Additionally, Solaris 7 will need it,
since inet_ntop and inet_pton reside there too.

[PATCH 3/8] diff-delta.c: "diff.h" is not a required include

[Brandon Casey]

From: Brandon Casey <drafnel@gmail.com>

This file (diff.h) provides declarations for some functions that are
implemented in diff-delta.c.  The SUNWspro C99 compiler complains about
it.  There is nothing defined in "diff.h" that is required by diff-delta.c,
so don't #include it.

[PATCH 4/8] On Solaris choose the OLD_ICONV iconv() declaration based on the UNIX spec

[Brandon Casey]

From: Brandon Casey <drafnel@gmail.com>

OLD_ICONV is only necessary on Solaris until UNIX03.  This is indicated
by the private macro _XPG6 which is set in /usr/include/sys/feature_tests.h.

[PATCH 5/8] git-compat-util.h: tweak the way _XOPEN_SOURCE is set on Solaris

[Brandon Casey]

From: Brandon Casey <drafnel@gmail.com>

On Solaris, when _XOPEN_EXTENDED is set, its header file forces the
programs to be XPG4v2, defeating any _XOPEN_SOURCE setting to say we are
XPG5 or XPG6.  Also on Solaris, XPG6 programs must be compiled with a c99
compiler, while non XPG6 programs must be compiled with a pre-c99 compiler.

So when compiling on Solaris, always refrain from setting _XOPEN_EXTENDED,
and then set _XOPEN_SOURCE to 600 or 500 based on whether a c99 compiler
is being used or not.

[PATCH 6/8] Makefile: define __sun__ on SunOS

[Brandon Casey]

From: Brandon Casey <drafnel@gmail.com>

The SUNWspro compiler does not define __sun__ (like GCC does).  A check of
this macro was recently added to detect compilation on SunOS and to modify
the handling of the NO_ICONV and _XOPEN_SOURCE feature macros.

[PATCH 7/8] Makefile: introduce SANE_TOOL_PATH for prepending required elements to PATH

[Brandon Casey]

From: Junio C Hamano <gitster@pobox.com>

Some platforms (like SunOS and family) have kept their common binaries at
some historical moment in time, and introduced new binaries with modern
features in a special location like /usr/xpg4/bin or /usr/ucb.  Some of the
features provided by these modern binaries are expected and required by git.
If the featureful binaries are not in the users path, then git could end up
using the less featureful binary and fail.

So provide a mechanism to prepend elements to the users PATH at runtime so
the modern binaries will be found.

I get this error when compiling using the SUNWspro c99 compiler
when delta.h is included in diff-delta.c:

"diff-delta.c", line 314: identifier redeclared: create_delta
        current : function(pointer to const struct delta_index {unsigned long memsize, pointer to const void src_buf, unsigned long src_size, unsigned int hash_mask, array[-1] of pointer to struct index_entry {..} hash}, pointer to const void, unsigned long, pointer to unsigned long, unsigned long) returning pointer to void

c99: acomp failed for diff-delta.c
gmake: *** [diff-delta.o] Error 2


I don't see any difference between those two "current" and "previous" statements.

I thought I knew why the error was occurring, but now I don't think I do.  There
are other function declarations in delta.h that are implemented in diff-delta.c,
and those functions are both declared and implemented _before_ create_delta in
delta.h and diff-delta.c respectively.

But, there does not seem to be anything declared in delta.h that is required by
diff-delta.c.

Maybe the commit message should be shortened to something more like:

   The SUNWspro C99 compiler complains: "identifier redeclared: create_delta" when
   delta.h is included.  There is nothing in "delta.h" that is required by
   diff-delta.c, so don't #include it.

Hmm, well, I just noticed that in the commit message I said "diff.h" everywhere when
I meant to say "delta.h".  Maybe that is the confusion.

NAK.

This is common practice to include the header file declaring function 
prototypes into the file defining the actual function so to make sure 
the declaration matches with the definition.  Deleting that include is 
actively ignoring a problem instead of fixing the cause of it.

It doesn't seem to like the structure being redeclared with a flex array
member and being passed as a const argument.


# cat > test.c <<EOF

struct a_struct;

extern void *test_func(const struct a_struct *f);

struct a_struct {
        int a;
        int b;
        char* c[];
};

void *test_func(const struct a_struct *f)
{
        return 0;
}
EOF

        previous: function(pointer to const struct a_struct {int a, int b, array[-1] of pointer to char c}) returning pointer to void : "test.c", line 4
c99: acomp failed for test.c


If either the flex array is removed from the structure, or const is removed from
test_func argument, test.c will compile.  Compiling with -O0 doesn't help.

What if you define FLEX_ARRAY to 1, or even 0?

If neither of those work then I'd simply remove the const.  Generated 
code should be exactly the same with gcc.  There is no const with 
sizeof_delta_index() which is already inconsistent.

Kind of weird nevertheless.

I tried that with my test.c example and '1' works, but not '0'.  I'll
try setting FLEX_ARRAY to 1 and running git's test suite on Monday.

Could you please add this build configuration variable to configure.ac
and config.mak.in, to be able to autodetect this situation?

I'll take a look at it, but autoconf is not a strong suit of mine.
Plus, I doubt I will actually be able to test anything on the
platforms I have access to that need to set NEEDS_RESOLV, since any
autoconf installation is likely to be very old.

> CC-ed Ralf Wildenhues and David Syzdek (who hopefully can produce

Yes please. :)

FYI:
Solaris 7 needs -lresov since inet_ntop and inet_pton reside there.
Additionally, since NO_IPV6 is set, hstrerror is called in connect.c
and hstrerror also resides in libresolv.

On more modern Solaris, inet_ntop and inet_pton reside somewhere else,
and since NO_IPV6 does not need to be set, -lresolv is not needed.

So this bit me already, and it's only been in next for a day. :) I
_already_ have /usr/xpg4/bin in my PATH before /usr/bin, but with this
patch, I get it stuck at the _beginning_ of my PATH automagically. Which
overrides, against my wishes, the "even more sane than /usr/xpg4/bin"
part of my PATH that comes at the beginning.

Specifically, I have "~peff/local/bin" at the beginning of my PATH which
contains a 'vi' that points to vim. Running "git rebase -i" now puts
/usr/xpg4/bin at the beginning of the PATH (before ~peff/local/bin),
which means I end up running the crappy system vi instead. For bonus
fun, "git commit" still runs the correct 'vi' because it doesn't happen
to be implemented as a shell script.

Am I crazy for not having EDITOR=vim instead of EDITOR=vi? Perhaps. But
I wanted to point out that tweaking the PATH behind the user's back does
cause surprises in the real world.

With the exception of 7/8 (which I already complained about separately),
these look reasonable to me, and my setup still passes the same tests
(though that is perhaps not saying much, as I was already using gcc).

Good points.  I'm fine with dropping this patch, especially when it causes
problems for a real Solaris user, which I'm not.

I don't like that git has a dependency on the user's PATH being set
correctly though.  That's why I liked the patch.  I guess I could modify
all the uses of sed and friends to look like $SED and then set SED to
/usr/xpg4/bin/sed on Solaris.  It doesn't sound like that is necessary
in practice though.

btw, this patch does help the test suite when the test suite is run using
make.  The patch added SANE_TOOL_PATH to PATH in the Makefile.

Let me point out that I'm also not a real Solaris user. These days all I
use it for is test-compiling git. So you can take my report with a grain
of salt.

Yeah, I think requiring the user's PATH to be set correctly and tweaking
the PATH behind the user's back are both unsatisfactory solutions. Using
$SED everywhere solves both problems, but would probably be quite
annoying to maintain. So I guess it is a matter of picking our poison.

In git-sh-setup, we do "unset CDPATH" ourselves to help and protect
clueless people, even though "people should have a sane environment".
Even though I suspect that anybody who is using Solaris for anything real
would not be using /usr/bin tools themselves (i.e. it should not be
necessary for us fixing their PATH), there may be people who do not know.
I think helping them with path munging falls into the same category, but
at the same time, the remedy looks worse than the disease.

We could further uglify the patch like this.

[PATCH] git-compat-util.h: avoid using c99 flex array feature with Sun compiler 5.8

[Brandon Casey]

From: Brandon Casey <drafnel@gmail.com>

The Sun c99 compiler as recent as version 5.8 Patch 121016-06 2007/08/01
produces an error when compiling diff-delta.c.  This source file #includes
the delta.h header file which pre-declares a struct which is later defined
to contain a flex array member.  The Sun c99 compiler fails to compile
diff-delta.c and gives the following error:

  "diff-delta.c", line 314: identifier redeclared: create_delta
          current : function(pointer to const struct delta_index {unsigned long memsize, pointer to const void src_buf, unsigned long src_size, unsigned int hash_mask, array[-1] of pointer to struct index_entry {..} hash}, pointer to const void, unsigned long, pointer to unsigned long, unsigned long) returning pointer to void
          previous: function(pointer to const struct delta_index {unsigned long memsize, pointer to const void src_buf, unsigned long src_size, unsigned int hash_mask, array[-1] of pointer to struct index_entry {..} hash}, pointer to const void, unsigned long, pointer to unsigned long, unsigned long) returning pointer to void : "delta.h", line 44
  c99: acomp failed for diff-delta.c

So, avoid using this c99 feature when compiling with the Sun c compilers
version 5.8 and older (the most recent version tested).

Signed-off-by: Brandon Casey <drafnel@gmail.com>

This should avoid the flex array problems when using the Sun c99 compiler.

This patch is on top of the new bc/solaris (a7a24ee7).

Since this checks the version of the Sun compiler, it should give Sun the
opportunity to fix the compiler in newer releases.  If someone has Sun
Studio 12? where __SUNPRO_C is set to 0x590, maybe they can test.
