For building PL/Perl, PL/Python, and PL/Tcl, we need a shared library of
libperl, libpython, and libtcl, respectively. Previously, this was
checked in the makefiles, skipping the PL build with a warning if no
shared library was available. Now this is checked in configure, with an
error if no shared library is available.
The previous situation arose because in the olden days, the configure
options --with-perl, --with-python, and --with-tcl controlled whether
frontend interfaces for those languages would be built. The procedural
languages were added later, and shared libraries were often not
available in the beginning. So it was decided skip the builds of the
procedural languages in those cases. The frontend interfaces have since
been removed from the tree, and shared libraries are now available most
of the time, so that setup makes much less sense now.
Also, the new setup allows contrib modules and pgxs users to rely on the
respective PLs being available based on configure flags.
The "check" target no longer needs to depend on "all", because it now
runs "install" directly, which in turn depends on "all". Doing both
will cause problems with parallel make, because two builds will run next
to each other.
Also remove the redirection of the temp-install output into a log file.
This was appropriate when this was done from within pg_regress, but now
it's just a regular make run, and especially with the above changes this
will now take the place of running the "all" target before the test
suites.
problem report by Jeff Janes, patch in part by Michael Paquier
Before, make check-world would create a new temporary installation for
each test suite, which is slow and wasteful. Instead, we now create one
test installation that is used by all test suites that are part of a
make run.
The management of the temporary installation is removed from pg_regress
and handled in the makefiles. This allows for better control, and
unifies the code with that of test suites not run through pg_regress.

more review by Fabien Coelho <coelho@cri.ensmp.fr>
Modern x86 and x86-64 processors with SSE 4.2 support have special
instructions, crc32b and crc32q, for calculating CRC-32C. They greatly
speed up CRC calculation.
Whether the instructions can be used or not depends on the compiler and the
target architecture. If generation of SSE 4.2 instructions is allowed for
the target (-msse4.2 flag on gcc and clang), use them. If they are not
allowed by default, but the compiler supports the -msse4.2 flag to enable
them, compile just the CRC-32C function with -msse4.2 flag, and check at
runtime whether the processor we're running on supports it. If it doesn't,
fall back to the slicing-by-8 algorithm. (With the common defaults on
current operating systems, the runtime-check variant is what you get in
practice.)
Abhijit Menon-Sen, heavily modified by me, reviewed by Andres Freund.
Use SSPI authentication to allow connections exclusively from the OS
user that launched the test suite. This closes on Windows the
vulnerability that commit be76a6d39e
closed on other platforms. Users of "make installcheck" or custom test
harnesses can run "pg_regress --config-auth=DATADIR" to activate the
same authentication configuration that "make check" would use.
Back-patch to 9.0 (all supported versions).
Security: CVE-2014-0067
PGXS computes srcdir from VPATH, PostgreSQL proper computes VPATH from
srcdir, and doing both results in an error from make. Conditionalize so
only one of these takes effect.
dblink and postgres_fdw use SHLIB_PREREQS = submake-libpq to build libpq
first. This doesn't work in a PGXS build, because there is no libpq to
build. So just omit setting SHLIB_PREREQS in this case.
Note that PGXS users can still use SHLIB_PREREQS (although it is not
documented). The problem here is only that contrib modules can be built
in-tree or using PGXS, and the prerequisite is only applicable in the
former case.
Commit 6697aa2bc2 previously attempted to
address this by creating a somewhat fake submake-libpq target in
Makefile.global. That was not the right fix, and it was also done in a
nonportable way, so revert that.
The prove program included in Perl 5.8 does not support the --ext
option, so don't use that and use wildcards on the command line instead.
Note that the tests will still all be skipped, because, for instance,
the version of Test::More is too old, but at least the regular
mechanisms for handling that will apply, instead of failing to call
prove altogether.
This improves consistency with the MSVC build. On buildfarm member
narwhal, since commit 846e91e022,
shfolder.dll:SHGetFolderPath() crashes when dblink calls it by way of
pqGetHomeDirectory(). Back-patch to 9.4, where that commit first
appeared. How it caused this regression remains a mystery. This is a
partial revert of commit 889f038129, which
adopted shfolder.dll for Windows NT 4.0 compatibility. PostgreSQL 8.2
dropped support for that operating system.
Building the documentation with XSLT does not check the DTD, like a
DSSSL build would. One can often get away with having invalid XML, but
the stylesheets might then create incorrect output, as they are not
designed to handle that. Therefore, check the validity of the XML
against the DTD, using xmllint, during the build.
Add xmllint detection to configure, and add some documentation.
xmllint comes with libxml2, which is already in use, but it might be in
a separate package, such as libxml2-utils on Debian.

The previous quoting caused "make -C src/bin check" to ignore, rather
than add to, any LD_LIBRARY_PATH content from the environment.
Back-patch to 9.4, where the macro was introduced.
Add some quotes in the makefile snippet that creates the temporary
installation, so that it can handle spaces in the directory name and
possibly some other oddities.
Instead of just erroring out when a tool is missing, wrap the call with
the "missing" script that we are already using for bison, flex, and
perl, so that the users get a useful error message.
Apparently, older versions of "prove" (couldn't identify the exact
version from the changelog) don't look into the t/ directory for tests
by default, so specify it explicitly.
When the TAP tests are run in-tree (make check), set the shared library
path using the appropriate environment variable, using a logic similar
to pg_regress, so that the right libraries are used.
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.

By default, lcov will call whatever gcov it can find in the path. But
if the user has specified a different gcov to configure, this could be
incompatible. So tell lcov explicitly with an option which gcov program
to call.
This feature, building on previous commits, allows the write-ahead log
stream to be decoded into a series of logical changes; that is,
inserts, updates, and deletes and the transactions which contain them.
It is capable of handling decoding even across changes to the schema
of the effected tables. The output format is controlled by a
so-called "output plugin"; an example is included. To make use of
this in a real replication system, the output plugin will need to be
modified to produce output in the format appropriate to that system,
and to perform filtering.
Currently, information can be extracted from the logical decoding
system only via SQL; future commits will add the ability to stream
changes via walsender.

Get rid of use of dlltool for linking the main postgres executable.
dlltool is obsolete and we'd prefer to stop depending on it.
Also, include $(LDAP_LIBS_FE) in $(libpq_pgport). (It's not clear that
this is really needed, or why it's not a linker bug if it is needed.
But reports are that it's needed on current Cygwin.)
We might want to back-patch this if it works, but first let's see
what the buildfarm thinks.

Continuing 63f32f3416, libpgcommon should
depend on libpgport, but not vice versa. But wait_result_to_str() in
wait_error.c depends on pstrdup() in libpgcommon. So move exec.c and
wait_error.c from libpgport to libpgcommon. Also switch the link order
in the place that's actually used by the failing ecpg builds.
The function declarations have been left in port.h for now. That should
perhaps be separated sometime.
Conceptually, libpgcommon can depend on libpgport, but not the other way
around. In the past, this might not have mattered, but it's needed now
for asprintf.
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.
A VPATH build will be performed when the module's make file path is not
the current directory or when USE_VPATH is set.
This will assist packagers and others who prefer to build without
polluting the source directories.
There is still a bit of work to do here, notably documentation, but it's
probably a good idea to commit what we have so far and let people test
it out on their modules.
Cédric Villemain, with an addition from me.
The build of .pc (pkg-config) files depends on all makefiles in use, and
in dependency tracking mode, the previous coding ended up including
/dev/null as a makefile. Apparently, on some platforms the modification
time of /dev/null changes sporadically, and so the .pc files would end
up being rebuilt every so often. Fix that by changing the makefile code
to do without using /dev/null.
libpgcommon is a new static library to allow sharing code among the
various frontend programs and backend; this lets us eliminate duplicate
implementations of common routines. We avoid libpgport, because that's
intended as a place for porting issues; per discussion, it seems better
to keep them separate.
The first use case, and the only implemented by this patch, is pg_malloc
and friends, which many frontend programs were already using.
At the same time, we can use this to provide palloc emulation functions
for the frontend; this way, some palloc-using files in the backend can
also be used by the frontend cleanly. To do this, we change palloc() in
the backend to be a function instead of a macro on top of
MemoryContextAlloc(). This was previously believed to cause loss of
performance, but this implementation has been tweaked by Tom and Andres
so that on modern compilers it provides a slight improvement over the
previous one.
This lets us clean up some places that were already with
localized hacks.
Most of the pg_malloc/palloc changes in this patch were authored by
Andres Freund. Zoltán Böszörményi also independently provided a form of
that. libpgcommon infrastructure was authored by Álvaro.
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.
Normally each module is tested in a database named contrib_regression,
which is dropped and recreated at the beginhning of each pg_regress run.
This new mode, enabled by adding USE_MODULE_DB=1 to the make command
line, runs most modules in a database with the module name embedded in
it.
This will make testing pg_upgrade on clusters with the contrib modules
a lot easier.
Second attempt at this, this time accomodating make versions older
than 3.82.
Still to be done: adapt to the MSVC build system.
Backpatch to 9.0, which is the earliest version it is reasonably
possible to test upgrading from.

The introduction of the .y -> .c pattern rule causes some .c files such
as bootparse.c to be considered intermediate files in the .y -> .c -> .o
rule chain, which make would automatically delete. But in coverage
mode, the processing tools such as genhtml need those files, so mark
them as "precious" so that make preserves them.
Numerous flex and bison make rules have appeared in the source tree
over time, and they are all virtually identical, so we can replace
them by pattern rules with some variables for customization.
Users of pgxs will also be able to benefit from this.
Get rid of the fundamentally indefensible assumption that "long long int"
exists and is exactly 64 bits wide on every platform Postgres runs on.
Instead let the configure script select the type to use for "pg_int64".
This is a bit of a pain in the rear since we do not want to pollute client
namespace with all the random symbols that pg_config.h defines; instead
we have to create a separate generated header file, "pg_config_ext.h".
But now that the infrastructure is there, we might have the ability to
add some other stuff that's long been wanting in this area.
The $(or) make function was introduced in GNU make 3.81, so the
previous coding didn't work in 3.80. Write it differently, and
improve the variable naming to make more sense in the new coding.
configure handles INSTALL as a substitution variable specially, and
apparently it gets confused when it's set to empty. Use INSTALL_
instead as a workaround to avoid the issue.
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.
According to the Autoconf documentation, there should be a make rule
pg_config.h: stamp-h
so that with the right setup around this, a change in pg_config.h.in
will trigger a rebuild of everything that depends on pg_config.h. But
this doesn't always work, sometimes you need to run make twice to get
everything up to date after a change of pg_config.h.in.
The fix is to write the rule as
pg_config.h: stamp-h ;
instead (with an empty command instead of no command). This is what
Automake-generated makefiles effectively do, so it seems safe to be on
this side.
It's not actually clear why this is (apparently) more correct. It's
been posted to
<http://lists.gnu.org/archive/html/help-make/2012-04/msg00058.html>
without response so far.
