On some platforms, -fpic fails for sufficiently large shared libraries.
We've mostly not hit that boundary yet, but there are some extensions
such as Citus and pglogical where it's becoming a problem. A bit of
research suggests that the penalty for -fPIC is small, in the
single-digit-percentage range --- and there's none at all on popular
platforms such as x86_64. So let's just default to -fPIC everywhere
and provide one less thing for extension developers to worry about.
Per complaint from Christoph Berg. Back-patch to all supported branches.
(I did not bother to touch the recently-removed Makefiles for sco and
unixware in the back branches, though. We'd have no way to test that
it doesn't break anything on those platforms.)

pgoutput evidently needs to be built without -DBUILDING_DLL. (It seems
like a pretty bad idea that these makefiles need to know exactly where
all the shlibs are in the tree, or maybe what's bad is putting them under
src/backend/. But right now is not the time to redesign that.)
Also, remove "override CPPFLAGS" in pgoutput's Makefile. I don't think
that that actually has any bad consequences, but it's certainly useless
in a directory that has no .h files, and it might be contributing to the
failure somehow.
Per buildfarm.

This allows us to avoid running the regression tests in contrib modules
like pg_stat_statement in a less ugly manner.

SCO OpenServer and SCO UnixWare are more or less dead platforms.
We have never had a buildfarm member testing the "sco" port, and
the last "unixware" member was last heard from in 2012, so it's
fair to doubt that the code even compiles anymore on either one.
Remove both ports. We can always undo this if someone shows up
with an interest in maintaining and testing these platforms.

overriden -> overridden
The misspelling in create_extension.sgml was introduced in b67aaf2,
so no need to backpatch.

Remove configure's checks for HAVE_POSIX_SIGNALS, HAVE_SIGPROCMASK, and
HAVE_SIGSETJMP. These APIs are required by the Single Unix Spec v2
(POSIX 1997), which we generally consider to define our minimum required
set of Unix APIs. Moreover, no buildfarm member has reported not having
them since 2012 or before, which means that even if the code is still live
somewhere, it's untested --- and we've made plenty of signal-handling
changes of late. So just take these APIs as given and save the cycles for
configure probes for them.
However, we can't remove as much C code as I'd hoped, because the Windows
port evidently still uses the non-POSIX code paths for signal masking.
Since we're largely emulating these BSD-style APIs for Windows anyway, it
might be a good thing to switch over to POSIX-like notation and thereby
remove a few more #ifdefs. But I'm not in a position to code or test that.
In the meantime, we can at least make things a bit more transparent by
testing for WIN32 explicitly in these places.

Commit 0ffc201a51395ca71fe429ef86c872850a5850ee included this object
unconditionally. Being unprepared for that, most external, single-file
modules failed to build. This better aligns the GNU make build system
with the heuristic in the MSVC build's Project::AddDirResourceFile().
In-tree, installed modules set PGFILEDESC, so they will see no change.
Also, under PGXS, omit the nonfunctioning rule to build win32ver.rc.
Back-patch to 9.5, where the aforementioned commit first appeared.
|
|
The PGXS-case directory does not exist in the non-PGXS case, and vice
versa. Add one or the other, not both. This is essentially cosmetic.
It makes Makefile.win32 more like the similar Makefile.global code.
|
|
Responsibility was formerly split between Makefile.global and pgxs.mk.
As a result of commit b58233c71b93a32fcab7219585cafc25a27eb769, in the
PGXS case, these variables were unset while parsing Makefile.global and
callees. Inclusion of Makefile.custom did not work from PGXS, and the
subtle difference seemed like a recipe for future bugs. Back-patch to
9.4, where that commit first appeared.

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
|
|
The temp-install target sets EXTRA_INSTALL to install the current
directory. But when doing so, it should append instead of overwrite,
otherwise settings of EXTRA_INSTALL from a makefile won't take effect.
This would cause the earthdistance test to fail when called directly,
because it would miss installing the cube module.
|
|
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.

These changes were originally submitted as "adds support for VPATH with
USE_PGXS", but they are not necessary for VPATH support, so they just
add more lines of code for no reason.
|
|
The user can just set VPATH directly. There is no need to invent
another variable.
|
|
Custom rules must come after pgxs inclusion, not before, because any
rule added before pgxs will break the default 'all' target.

When commit 846e91e0223cf9f2821c3ad4dfffffbb929cb027 switched the linker
driver from dlltool/dllwrap to gcc, it became possible for linking to
choose shared libgcc. Backends having loaded a module dynamically
linked to libgcc can exit abnormally, which the postmaster treats like a
crash. Resume use of static libgcc exclusively, like 9.3 and earlier.
Back-patch to 9.4.

Prominent binaries already had this metadata. A handful of minor
binaries, such as pg_regress.exe, still lack it; efforts to eliminate
such exceptions are welcome.

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.
|
|
The MSVC build process already did so; this fixes the principal build
process to match. Both processes already did likewise for src/common.
This lets server builds of src/port reference postgres.exe data symbols.
|
|
Even if this is needed, it'd be configure's responsibility to set it.
|
|
We are almost completely out of the dlltool game, if this works.
Hiroshi Inoue
|
|
The preferred method is to use "cc -shared", and this allows binaries
to be rebased if required, unlike dllwrap.
Backpatch to 9.0 where we have buildfarm coverage.
There are still some issues with Cygwin, especially modern Cygwin, but
this helps us get closer to good support.

Bug introduced by commit 6697aa2bc25c83b88d6165340348a31328c35de6 and
reported by Robert Haas.
|
|
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.

Apparently, they need -DBUILDING_DLL for the Assert() declarations to
work correctly.

Complaint and patch from Zoltán Böszörményi.
When cross-compiling, the native make doesn't know
about the Windows .exe suffix, so it only builds with
it when explicitly told to do so.
The native make will not see the link between the target
name and the built executable, and might this do unnecesary
work, but that's a bigger problem than this one, if in fact
we consider it a problem at all.
Back-patch to all live branches.
|
|
This was used in a time when a shared libperl or libpython was difficult
to come by. That is obsolete, and the idea behind the flag was never
fully portable anyway and will likely fail on more modern CPU
architectures.

database.
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 previous coding worked as long as MODULEDIR wasn't set explicitly,
because we create sharedir/$(datamoduledir) and the default value of
that is "extension". But if some other value is specified for MODULEDIR
then the installation directory needed for the control file wasn't made.

Building a shlib on AIX requires use of the mkldexport.sh script, but we
failed to install that, preventing its use from non-source-tree contexts.
Also, Makefile.aix had the wrong idea about where to find the installed
copy of the postgres.imp symbol file used by AIX.
Per report from John Pierce. Patch all the way back, since this has been
broken since the beginning of PGXS.

Postgres 9.2, and perhaps no existing users either.
|

Remove the following ports:
- dgux
- nextstep
- sunos4
- svr4
- ultrix4
- univel
These are obsolete and not worth rescuing. In most cases, there is
circumstantial evidence that they wouldn't work anymore anyway.
|
|
Otherwise, the availability of these variables depends on what
happened to be available at the time the PostgreSQL build was
configured.
|
|
It runs the regression tests, runs pg_upgrade on the populated
database, and compares the before and after dumps. While not actually
a cross-version upgrade, this does detect omissions and bugs in the
involved tools from time to time. It's also possible to do a
cross-version upgrade by manually supplying parameters.
|
|
The previous coding resulted in contrib modules unintentionally overriding
the use of CONTRIB_TESTDB. There seems no particularly good reason to
allow that (after all, the makefile can set CONTRIB_TESTDB if that's really
what it intends).
In passing, document REGRESS_OPTS where the other pgxs.mk options are
documented.
Back-patch to 9.1 --- in prior versions, there were no cases of contrib
modules setting REGRESS_OPTS without including the --dbname switch, so
while the coding was fragile there was no actual bug.
|

This probably needs more work, but it's a start.

Per recommendation from Peter. Neither choice is bulletproof, but this
is the existing style and it does help prevent unexpected environment
variable substitution.
|

install-sh can install multiple files at once, so for loops are not
necessary. This was already changed for the rest of the code some
time ago, but pgxs.mk was apparently forgotten, and the obsolete
coding style has now been copied to the PLs as well.
This also fixes the problem that the for loops in question did not
catch errors.
|
|
Added a new option --extra-install to pg_regress to arrange installing
the respective contrib directory into the temporary installation.
This is currently not yet supported for Windows MSVC builds.
Updated the .gitignore files for contrib modules to ignore the
leftovers of a temp-install check run.
Changed the exit status of "make check" in a pgxs build (which still
does nothing) to 0 from 1.
Added "make check" in contrib to top-level "make check-world".
|
|
Also add make check-world target, and refactor pg_regress invocation
code in makefiles a bit.
|
|
Arrange for the control files to be in $SHAREDIR/extension not
$SHAREDIR/contrib, since we're generally trying to deprecate the term
"contrib" and this is a once-in-many-moons opportunity to get rid of it in
install paths. Fix PGXS to install the $EXTENSION file into that directory
no matter what MODULEDIR is set to; a nondefault MODULEDIR should only
affect the script and secondary extension files. Fix the control file
directory parameter to be interpreted relative to $SHAREDIR, to avoid a
surprising disconnect between how you specify that and what you set
MODULEDIR to.
Per discussion with David Wheeler.

This patch adds the server infrastructure to support extensions.
There is still one significant loose end, namely how to make it play nice
with pg_upgrade, so I am not yet committing the changes that would make
all the contrib modules depend on this feature.
In passing, fix a disturbingly large amount of breakage in
AlterObjectNamespace() and callers.
