Noah Misch	acd73ad1a1	Code review for avoidance of direct cross-module links. Remove $(pkglibdir) from $(rpathdir), since commits `d51924be88` and `eda04886c1` removed direct linkage to objects stored there. Users are unlikely to notice the difference. Accompany every $(python_libspec) with $(python_additional_libs); this doesn't fix a demonstrated bug, but it might do so on rare Python configurations. With these changes, AIX ceases to be a special case.	9 years ago
Tom Lane	d51924be88	Convert contrib/hstore_plpython to not use direct linking to other modules. Previously, on most platforms, we allowed hstore_plpython's references to hstore and plpython to be unresolved symbols at link time, trusting the dynamic linker to resolve them when the module is loaded. This has a number of problems, the worst being that the dynamic linker does not know where the references come from and can do nothing but fail if those other modules haven't been loaded. We've more or less gotten away with that for the limited use-case of datatype transform modules, but even there, it requires some awkward hacks, most recently commit `83c249200`. Instead, let's not treat these references as linker-resolvable at all, but use function pointers that are manually filled in by the module's _PG_init function. There are few enough contact points that this doesn't seem unmaintainable, at least for these use-cases. (Note that the same technique wouldn't work at all for decoupling from libpython itself, but fortunately that's just a standard shared library and can be linked to normally.) This is an initial patch that just converts hstore_plpython. If the buildfarm doesn't find any fatal problems, I'll work on the other transform modules soon. Tom Lane, per an idea of Andres Freund's.

Tom Lane	3343ea9e8e	Sort $(wildcard) output where needed for reproducible build output. The order of inclusion of .o files makes a difference in linker output; not a functional difference, but still a bitwise difference, which annoys some packagers who would like reproducible builds.

Andrew Dunstan	00eff86cb8	Enable transforms modules to build and test on Cygwin. This still doesn't work correctly with Python 3, but I am committing this so we can get Cygwin buildfarm members building with Python 2.	11 years ago
Noah Misch	7193436744	AIX: Link TRANSFORM modules with their dependencies. The result closely resembles linking of these modules for the "win32" port. Augment the $(exports_file) header so the file is also usable as an import file. Unfortunately, relocating an AIX installation will now require adding $(pkglibdir) to LD_LIBRARY_PATH. Back-patch to 9.5, where the modules were introduced.	11 years ago
Tom Lane	b14cf229f4	Use += not = to set makefile variables after including base makefiles. The previous coding in hstore_plpython and ltree_plpython wiped out any values set by the base makefiles. This at least had the effect of running the tests in "regression" not "contrib_regression" as expected. These being pretty new modules, there might be other bad effects we'd not noticed yet.	11 years ago
Andrew Dunstan	f802c6ddba	Enable transforms modules to build and run with Mingw builds. These modules were all missing essential Windows scaffolding, including resources files and descriptions, and links to the relevant library import files. This latter item means that the modules can't be built with pgxs on Windows, as we don't install the import files. If we ever decide to install them this restriction could probably be removed. Also, as with plperl we need to make sure that perl's CORE directory is last on the include list, as on Windows it appears to contain some headers with names that clash with names of some headers we include.	11 years ago
Peter Eisentraut	cac7658205	Add transforms feature This provides a mechanism for specifying conversions between SQL data types and procedural languages. As examples, there are transforms for hstore and ltree for PL/Perl and PL/Python. reviews by Pavel Stěhule and Andres Freund	11 years ago
