d7cdf6ee36 Diagnose incompatible OpenLDAP versions during build and test.
With OpenLDAP versions 2.4.24 through 2.4.31, inclusive, PostgreSQL
backends can crash at exit.  Raise a warning during "configure" based on
the compile-time OpenLDAP version number, and test the crash scenario in
the dblink test suite.  Back-patch to 9.0 (all supported versions).

5571caf42d Move check for SSL_get_current_compression to run on mingw
Mingw uses a different header file than msvc, so we don't get the
hardcoded value, so we need the configure test to run.

c9e1ad7faf Detect presence of SSL_get_current_compression
Apparently we still build against OpenSSL so old that it doesn't
have this function, so add an autoconf check for it to make the
buildfarm happy. If the function doesn't exist, always return
that compression is disabled, since presumably the actual
compression functionality is always missing.

For now, hardcode the function as present on MSVC, since we should
hopefully be well beyond those old versions on that platform.

a16bac36ec Remove dependency on wsock32.lib in favor of ws2_32
ws2_32 is the new version of the library that should be used, as
it contains the require functionality from wsock32 as well as some
more (which is why some binaries were already using ws2_32).

2e8ce9ae46 Remove some useless code in the configure script.
Almost ten years ago, commit e48322a6d6 broke
the logic in ACX_PTHREAD by looping through all the possible flags rather
than stopping with the first one that would work.  This meant that
$acx_pthread_ok was no longer meaningful after the loop; it would usually
be "no", whether or not we'd found working thread flags.  The reason nobody
noticed is that Postgres doesn't actually use any of the symbols set up
by the code after the loop.  Rather than complicate things some more to
make it work as designed, let's just remove all that dead code, and thereby
save a few cycles in each configure run.

a6d488cb53 Remove Alpha and Tru64 support.
Support for running postgres on Alpha hasn't been tested for a long
while. Due to Alpha's uniquely lax cache coherency model it's a hard
to develop for platform (especially blindly!) and thought to be
unlikely to currently work correctly.

As Alpha is the only supported architecture for Tru64 drop support for
it as well. Tru64's support has ended 2012 and it has been in
maintenance-only mode for much longer.

Also remove stray references to __ksr__ and ultrix defines.

20561acf93 On OS X, link libpython normally, ignoring the "framework" framework.
As of Xcode 5.0, Apple isn't including the Python framework as part of the
SDK-level files, which means that linking to it might fail depending on
whether Xcode thinks you've selected a specific SDK version.  According to
their Tech Note 2328, they've basically deprecated the framework method of
linking to libpython and are telling people to link to the shared library
normally.  (I'm pretty sure this is in direct contradiction to the advice
they were giving a few years ago, but whatever.)  Testing says that this
approach works fine at least as far back as OS X 10.4.11, so let's just
rip out the framework special case entirely.  We do still need a special
case to decide that OS X provides a shared library at all, unfortunately
(I wonder why the distutils check doesn't work ...).  But this is still
less of a special case than before, so it's fine.

Back-patch to all supported branches, since we'll doubtless be hearing
about this more as more people update to recent Xcode.

b8cc8f9473 Support BSD and e2fsprogs UUID libraries alongside OSSP UUID library.
Allow the contrib/uuid-ossp extension to be built atop any one of these
three popular UUID libraries.  (The extension's name is now arguably a
misnomer, but we'll keep it the same so as not to cause unnecessary
compatibility issues for users.)

We would not normally consider a change like this post-beta1, but the issue
has been forced by our upgrade to autoconf 2.69, whose more rigorous header
checks are causing OSSP's header files to be rejected on some platforms.
It's been foreseen for some time that we'd have to move away from depending
on OSSP UUID due to lack of upstream maintenance, so this is a down payment
on that problem.

While at it, add some simple regression tests, in hopes of catching any
major incompatibilities between the three implementations.

ac4ef637ad Allow use of "z" flag in our printf calls, and use it where appropriate.
Since C99, it's been standard for printf and friends to accept a "z" size
modifier, meaning "whatever size size_t has".  Up to now we've generally
dealt with printing size_t values by explicitly casting them to unsigned
long and using the "l" modifier; but this is really the wrong thing on
platforms where pointers are wider than longs (such as Win64).  So let's
start using "z" instead.  To ensure we can do that on all platforms, teach
src/port/snprintf.c to understand "z", and add a configure test to force
use of that implementation when the platform's version doesn't handle "z".

Having done that, modify a bunch of places that were using the
unsigned-long hack to use "z" instead.  This patch doesn't pretend to have
gotten everyplace that could benefit, but it catches many of them.  I made
an effort in particular to ensure that all uses of the same error message
text were updated together, so as not to increase the number of
translatable strings.

It's possible that this change will result in format-string warnings from
pre-C99 compilers.  We might have to reconsider if there are any popular
compilers that will warn about this; but let's start by seeing what the
buildfarm thinks.

ed011d9754 Undo autoconf 2.69's attempt to #define _DARWIN_USE_64_BIT_INODE.
Defining this symbol causes OS X 10.5 to use a buggy version of readdir(),
which can sometimes fail with EINVAL if the previously-fetched directory
entry has been deleted or renamed.  In later OS X versions that bug has
been repaired, but we still don't need the #define because it's on by

09a89cb5fc Get rid of use of asprintf() in favor of a more portable implementation.
asprintf(), aside from not being particularly portable, has a fundamentally
badly-designed API; the psprintf() function that was added in passing in
the previous patch has a much better API choice.  Moreover, the NetBSD
implementation that was borrowed for the previous patch doesn't work with
non-C99-compliant vsnprintf, which is something we still have to cope with
on some platforms; and it depends on va_copy which isn't all that portable
either.  Get rid of that code in favor of an implementation similar to what
we've used for many years in stringinfo.c.  Also, move it into libpgcommon
since it's not really libpgport material.

I think this patch will be enough to turn the buildfarm green again, but
there's still cosmetic work left to do, namely get rid of pg_asprintf()
in favor of using psprintf().  That will come in a followon patch.

b853eb9718 Improve handling of ereport(ERROR) and elog(ERROR).
In commit 71450d7fd6, we added code to inform
suitably-intelligent compilers that ereport() doesn't return if the elevel
is ERROR or higher.  This patch extends that to elog(), and also fixes a
double-evaluation hazard that the previous commit created in ereport(),
as well as reducing the emitted code size.

The elog() improvement requires the compiler to support __VA_ARGS__, which
should be available in just about anything nowadays since it's required by
C99.  But our minimum language baseline is still C89, so add a configure
test for that.

The previous commit assumed that ereport's elevel could be evaluated twice,
which isn't terribly safe --- there are already counterexamples in xlog.c.
On compilers that have __builtin_constant_p, we can use that to protect the
second test, since there's no possible optimization gain if the compiler
doesn't know the value of elevel.  Otherwise, use a local variable inside
the macros to prevent double evaluation.  The local-variable solution is
inferior because (a) it leads to useless code being emitted when elevel
isn't constant, and (b) it increases the optimization level needed for the
compiler to recognize that subsequent code is unreachable.  But it seems
better than not teaching non-gcc compilers about unreachability at all.

Lastly, if the compiler has __builtin_unreachable(), we can use that
instead of abort(), resulting in a noticeable code savings since no
function call is actually emitted.  However, it seems wise to do this only
in non-assert builds.  In an assert build, continue to use abort(), so that
the behavior will be predictable and debuggable if the "impossible"
happens.

These changes involve making the ereport and elog macros emit do-while
statement blocks not just expressions, which forces small changes in
a few call sites.

b966dd6c42 Add fsync capability to initdb, and use sync_file_range() if available.
Historically we have not worried about fsync'ing anything during initdb
(in fact, initdb intentionally passes -F to each backend launch to prevent
it from fsync'ing).  But with filesystems getting more aggressive about
caching data, that's not such a good plan anymore.  Make initdb do a pass
over the finished data directory tree to fsync everything.  For testing
purposes, the -N/--nosync flag can be used to restore the old behavior.

Also, testing shows that on Linux, sync_file_range() is much faster than
posix_fadvise() for hinting to the kernel that an fsync is coming,
apparently because the latter blocks on a rather small request queue while
the former doesn't.  So use this function if available in initdb, and also
in the backend's pg_flush_data() (where it currently will affect only the
speed of CREATE DATABASE's cloning step).

We will later make pg_regress invoke initdb with the --nosync flag
to avoid slowing down cases such as "make check" in contrib.  But
let's not do so until we've shaken out any portability issues in this
patch.

fc548b2296 Remove support for using wait3() in place of waitpid().
All Unix-oid platforms that we currently support should have waitpid(),
since it's in V2 of the Single Unix Spec.  Our git history shows that
the wait3 code was added to support NextStep, which we officially dropped
support for as of 9.2.  So get rid of the configure test, and simplify the
macro spaghetti in reaper().  Per suggestion from Fujii Masao.

9db7ccae20 Use system install program when available and usable
In a3176dac22 we switched to using
install-sh unconditionally, because the configure check
AC_PROG_INSTALL would pick up any random program named install, which
has caused failure reports
(http://archives.postgresql.org/pgsql-hackers/2001-03/msg00312.php).
Now the configure check is much improved and should avoid false
positives.  It has also been shown that using a system install program
can significantly reduce "make install" times, so it's worth trying.

f2386d7136 Fix configure's search for collateindex.pl.
PGAC_PATH_COLLATEINDEX supposed that it could use AC_PATH_PROGS to search
for collateindex.pl, but that macro will only accept files that are marked
executable, and at least some DocBook installations don't mark the script
executable (a case the docs Makefile was already prepared for).  Accept the
script if it's present and readable in $DOCBOOKSTYLE/bin, and otherwise
search the PATH as before.

Having fixed that up, we don't need the fallback case that was in the docs
Makefile, and instead can throw an understandable error if configure didn't
find the script.  Per recent trouble report from John Lumby.

4f658dc851 Support fls().
The immediate impetus for this is that Noah Misch's patch to elide
unnecessary table and index rebuilds when changing typmod for temporal
types uses it; and this is extracted from that patch, with some
further commentary by me.  But it seems logically separate from the
remainder of the patch, so I'm committing it separately; this is not
the first time someone has wanted fls() in the backend and probably
won't be the last.

If we end up using this in more performance-critical spots it may be
worthwhile to add some architecture-specific optimizations to our
src/port version of fls() - e.g. any x86 platform can implement this
using the assembly instruction BSRL.  But performance won't matter
a bit for assessing typmod changes, so I'm not worried about that
right now.

0a41e86584 Use __sync_lock_test_and_set() for spinlocks on ARM, if available.
Historically we've used the SWPB instruction for TAS() on ARM, but this
is deprecated and not available on ARMv6 and later.  Instead, make use
of a GCC builtin if available.  We'll still fall back to SWPB if not,
so as not to break existing ports using older GCC versions.

Eventually we might want to try using __sync_lock_test_and_set() on some
other architectures too, but for now that seems to present only risk and
not reward.

Back-patch to all supported versions, since people might want to use any
of them on more recent ARM chips.

5cfa8dd300 Use mutex hint bit in PPC LWARX instructions, where possible.
The hint bit makes for a small but measurable performance improvement
in access to contended spinlocks.

On the other hand, some PPC chips give an illegal-instruction failure.
There doesn't seem to be a completely bulletproof way to tell whether the
hint bit will cause an illegal-instruction failure other than by trying
it; but most if not all 64-bit PPC machines should accept it, so follow
the Linux kernel's lead and assume it's okay to use it in 64-bit builds.
Of course we must also check whether the assembler accepts the command,
since even with a recent CPU the toolchain could be old.

4af43ee3f1 Make pgbench use erand48() rather than random().
glibc renders random() thread-safe by wrapping a futex lock around it;
testing reveals that this limits the performance of pgbench on machines
with many CPU cores.  Rather than switching to random_r(), which is
only available on GNU systems and crashes unless you use undocumented
alchemy to initialize the random state properly, switch to our built-in
implementation of erand48(), which is both thread-safe and concurrent.

Since the list of reasons not to use the operating system's erand48()
is getting rather long, rename ours to pg_erand48() (and similarly
for our implementations of lrand48() and srand48()) and just always
use those.  We were already doing this on Cygwin anyway, and the
glibc implementation is not quite thread-safe, so pgbench wouldn't
be able to use that either.

Per discussion with Tom Lane.

cacd42d62c Rewrite libxml error handling to be more robust.
libxml reports some errors (like invalid xmlns attributes) via the error
handler hook, but still returns a success indicator to the library caller.
This causes us to miss some errors that are important to report.  Since the
"generic" error handler hook doesn't know whether the message it's getting
is for an error, warning, or notice, stop using that and instead start
using the "structured" error handler hook, which gets enough information
to be useful.

While at it, arrange to save and restore the error handler hook setting in
each libxml-using function, rather than assuming we can set and forget the
hook.  This should improve the odds of working nicely with third-party
libraries that also use libxml.

In passing, volatile-ize some local variables that get modified within
PG_TRY blocks.  I noticed this while testing with an older gcc version
than I'd previously tried to compile xml.c with.

dbbba5279f Start using flexible array members
Flexible array members are a C99 feature that avoids "cheating" in the
declaration of variable-length arrays at the end of structs.  With
Autoconf support, this should be transparent for older compilers.

We start with one use in gist.h because gcc 4.6 started to raise a
warning there.  Over time, it can be expanded to other places in the
source, but they will likely need some review of sizeof and offsetof
usage.  The current change in gist.h appears to be safe in this
regard.

be4585b1c2 Replace use of credential control messages with getsockopt(LOCAL_PEERCRED).
It turns out the reason we hadn't found out about the portability issues
with our credential-control-message code is that almost no modern platforms
use that code at all; the ones that used to need it now offer getpeereid(),
which we choose first.  The last holdout was NetBSD, and they added
getpeereid() as of 5.0.  So far as I can tell, the only live platform on
which that code was being exercised was Debian/kFreeBSD, ie, FreeBSD kernel
with Linux userland --- since glibc doesn't provide getpeereid(), we fell
back to the control message code.  However, the FreeBSD kernel provides a
LOCAL_PEERCRED socket parameter that's functionally equivalent to Linux's
SO_PEERCRED.  That is both much simpler to use than control messages, and
superior because it doesn't require receiving a message from the other end
at just the right time.

Therefore, add code to use LOCAL_PEERCRED when necessary, and rip out all
the credential-control-message code in the backend.  (libpq still has such
code so that it can still talk to pre-9.1 servers ... but eventually we can
get rid of it there too.)  Clean up related autoconf probes, too.

This means that libpq's requirepeer parameter now works on exactly the same
platforms where the backend supports peer authentication, so adjust the
documentation accordingly.
