make maintainer-check was obscure and rarely called in practice, and
many breakages were missed. Fold everything that make maintainer-check
used to do into the normal build. Specifically:
- Call duplicate_oids when genbki.pl is called.
- Check for tabs in SGML files when the documentation is built.
- Run msgfmt with the -c option during the regular build. Add an
additional configure check to see whether we are using the GNU
version. (make maintainer-check probably used to fail with non-GNU
msgfmt.)
Keep maintainer-check as around as phony target for the time being in
case anyone is calling it. But it won't do anything anymore.
This is just neatnik-ism, since all the tests in the code are #ifdefs,
but we shouldn't specify symbols as "Define to 1 ..." and then not
actually define them that way.
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.

This means we can now construct a configure test for the library
presence. Previously these parameters were only figured out at
build time in plperl's GnuMakefile.
Pre-Lion versions of Apple's linker don't allow space between -F and its
argument. (Snow Leopard is nice enough to tell you that in so many words,
but older versions just fail with very obscure link errors, as seen on
buildfarm member locust for instance.) Oversight in commit
fc8745070a.
The PL/Python build on OS X was previously hardcoded to use the system
installation of Python, ignoring whatever was specified to configure.
Except that it would use the header files from configure, which could
lead to mismatches. It was not possible to build against a custom
Python installation.
Now, we check in configure how the specified Python installation was
built and use that, supporting framework and non-framework builds.
The former name was too likely to conflict with symbols from external
headers; and, as seen in recent buildfarm failures in member spoonbill,
it has now happened at least in plpython.
Currently, the macros only work with fairly recent gcc versions, but there
is room to expand them to other compilers that have comparable features.
Heavily revised and autoconfiscated version of a patch by Andres Freund.
Python can be built to have two separate include directories: one for
platform-independent files and one for platform-specific files. So
far, this has apparently never mattered for a PL/Python build. But
with the new multi-arch Python packages in Debian and Ubuntu, this is
becoming the standard configuration on these platforms, so we must
check these directories separately to be able to build there.
Also add a bit of reporting in configure to be able to see better what
is going on with this.
There was a hack put into install-sh to call strip with the correct
options on Mac OS X. But that never worked, because configure
disabled stripping on that platform altogether. So remove that dead
code, and while we're at it, update install-sh to the latest upstream
source (from Automake).
Instead, set up the right strip options in programs.m4, so this now
actually works the way it was originally intended.
The BSD-ish members of the buildfarm all seem to think removing this
was a bad idea. It looks to me like it resulted in omitting the system
header inclusion necessary to detect the fields of struct tm correctly.

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.
Original patch by Lars Kanis, reviewed by Nishiyama Tomoaki and tweaked some by me.
This compiler, or at least the latest version of it, is currently broken, and
only passes the regression tests if built with -O0.
Because of ABI tagging, the library version number might no longer be
exactly the Python version number, so do extra lookups. This affects
installations without a shared library, such as ActiveState's
installer.
Also update the way to detect the location of the 'config' directory,
which can also be versioned.

This is reported to be necessary on some versions of that OS. In service
of this, cause PGAC_PROG_CC_CFLAGS_OPT to reject switches that result in
compiler warnings, since on yet other versions of that OS, the switch does
nothing except provoke a warning.
Report and patch by Ibrar Ahmed, further tweaking by me.
When testing the stderr produced by various thread-support flags, also
run a compilation in addition to a link, because clang warns on
certain flags when compiling but not when linking.
This adds collation support for columns and domains, a COLLATE clause
to override it per expression, and B-tree index support.

build tree. If we actually build the docs in the VPATH tree, those dirs
will get created then; but if they're present and empty, they capture the
vpathsearch searches in "make install", preventing installation of prebuilt
docs that might exist in the source tree. Per bug #5595 from Dmtiriy Igrishin.
Fix based on idea from Peter Eisentraut.
This variable is apparently only for Python internally. In newer releases
of Python this variable pulls in more and more libraries that users are
less likely to have, leading to potential build failures.
compilers, by applying a configure check to see if the compiler will accept
an unreferenced "static inline foo ..." function without warnings. It is
believed that such warnings are the only reason not to declare inlined
functions in headers, if the compiler understands "inline" at all.

versions < 5.8. Also, if there's no Perl, emit a warning informing the
user that he won't be able to build from a CVS pull. This is exactly the
same treatment we give Bison and Perl, and for the same reasons.
Behaves more or less unchanged compared to Python 2, but the new language
variant is called plpython3u. Documentation describing the naming scheme
is included.
shell construct to hide away the stderr output. Python 3.1 actually core
dumps on the current invocation (http://bugs.python.org/issue7111), but the
new version also has the more general advantage of saving the error message
in config.log for analysis.
perl_embed_ldflags setting. On OS X it seems that ExtUtils::Embed is
trying to force a universal binary to be built, but you need to specify
that a lot further upstream if you want Postgres built that way; the only
result of including -arch in perl_embed_ldflags is some warnings at the
plperl.so link step. Per my complaint and Jan Otto's suggestion.
Update install-sh to that from Autoconf 2.63, plus our Darwin-specific
changes (which I simplified a bit). install-sh is now able to install
multiple files in one run, so we could simplify our makefiles sometime.
install-sh also now has a -d option to create directories, so we don't need
mkinstalldirs anymore.
Use AC_PROG_MKDIR_P in configure.in, so we can use mkdir -p when available
instead of install-sh -d. For consistency with the rest of the world,
the corresponding make variable has been renamed from $(mkinstalldirs) to
$(MKDIR_P).
This switches the man page building process to use the DocBook XSL stylesheet
toolchain. The previous targets for Docbook2X are removed. configure has been
updated to look for the new tools. The Documentation appendix contains the
new build instructions. There are also a few isolated tweaks in the
documentation to improve places that came out strangely in the man pages.
update documentation accordingly. This is required in order to have support
for a reentrant scanner. I'm committing this bit separately in order to have
an easy reference if we later decide to make the minimum something different
(like 2.5.33).
This upgrades the configure infrastructure to the latest Autoconf version.
Some notable news are:
- The workaround for the broken fseeko() test is gone.
- Checking for unknown options is now provided by Autoconf itself.
- Fixes for Mac OS X
used to work as intended, but got broken some time ago (a quoted empty string
is not an empty string), and got broken some more by the changes to generate
ecpg's preproc.y automatically. Given all the unprotected uses of $(PERL)
elsewhere, it seems best to make use of the $(missing) script rather than
trying to ensure each such use is protected individually. Also fix various
bits of documentation that omitted to mention Perl as a requirement for
building from a CVS pull. Per a complaint from Robert Haas.
print foo --> print(foo)
string.join(...) --> ' '.join(...)
These changes are backward compatible.
The actual plpython module appears to need significant updates to support
Python 3.0, though. This change just relieves interested developers from
having to deal with Autoconf.

shared libraries. We've tried this before and had problems with libreadline
not linking properly on some platforms, but that seems to be a libreadline
bug that may have been fixed by now. In any case, it's early enough in the
8.4 devel cycle that we can afford to have some transient breakage while
we work out any portability problems.
On Darwin, we try -Wl,-dead_strip_dylibs, which seems to be the equivalent
incantation there.

I added a CREATE FUNCTION to account for existing seg_center() code in seg.c
too, and some tests for it and the neighbor functions. At the same time,
remove checks for NULL which are not needed (because the functions are declared
STRICT).
I had to do some adjustments to contrib's btree_gist too. The choices for
representation there are not ideal for changing the underlying types :-(
Original patch by Zoltan Boszormenyi, with some adjustments by me.
- Change configure.in to use Autoconf 2.61 and update generated files.
- Update build system and documentation to support now directory variables
offered by Autoconf 2.61.
- Replace usages of PGAC_CHECK_ALIGNOF by AC_CHECK_ALIGNOF, now available
in Autoconf 2.61.
- Drop our patched version of AC_C_INLINE, as Autoconf now has the change.
code relies on the checking macro actually being called at the end, or the
automatic undiversion will produce garbage. These sort of implicit
side-effects undermine the modularity of the macros and happen to break the
ODBC driver which makes use of them.
Also put the warnings at the very end of configure, so there is an even
better chance of seeing them.

reliably (ie, regardless of which libraries they depend on). Also
make sure that we don't select headers that obviously belong to the
wrong one of the two libraries. This was discussed back around 4-Sep
but seems to have slipped through the cracks. The header selection
could be checked more closely, perhaps, but let's see if this is good
enough.
compiler emits any warnings, the test program had better be 100%
correct, not only 90% correct. The recent addition of -Wold-style-definition
broke thread-safety detection on every platform that has that switch,
because the test program used an old-style definition.
