Tom Lane	fb6fcbd33f	Use LOAD not actual code execution to pull in plpython library. Commit `866566a690` is insufficient to prevent dump/reload failures when using transform modules in a database with both plpython2 and plpython3 installed. The reason is that the transform extension scripts use DO blocks as a mechanism to pull in the libpython library before creating the transform function. It's necessary to preload the library because the dynamic loader won't do it for us on every platform, leading to "unresolved symbol" failures when the transform library is loaded. But it's not necessary to execute Python code, and doing so will provoke a multiple-Pythons-are-loaded error even after the preceding commit. To fix, use LOAD instead of a DO block. That requires superuser privilege, but creation of a C function does anyway. It also embeds knowledge of the underlying library name for each PL language; but that's wired into the initdb-time contents of pg_pltemplate too, so that doesn't seem like a large problem either. Note that CREATE TRANSFORM as such doesn't call the language module at all. Per a report from Paul Jones. Back-patch to 9.5 where transform modules were introduced.	10 years ago
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.

Tom Lane	68c1d7d42e	Dodge a macro-name conflict with Perl. Some versions of Perl export a macro named HS_KEY. This creates a conflict in contrib/hstore_plperl against hstore's macro of the same name. The most future-proof solution seems to be to rename our macro; I chose HSTORE_KEY. For consistency, rename HS_VAL and related macros similarly. Back-patch to 9.5. contrib/hstore_plperl doesn't exist before that so there is no need to worry about the conflict in older releases. Per reports from Marco Atzeri and Mike Blackwell.	10 years ago
Andres Freund	b67aaf21e8	Add CASCADE support for CREATE EXTENSION. Without CASCADE, if an extension has an unfullfilled dependency on another extension, CREATE EXTENSION ERRORs out with "required extension ... is not installed". That is annoying, especially when that dependency is an implementation detail of the extension, rather than something the extension's user can make sense of. In addition to CASCADE this also includes a small set of regression tests around CREATE EXTENSION.

Tom Lane	0426f349ef	Rearrange the handling of error context reports. Remove the code in plpgsql that suppressed the innermost line of CONTEXT for messages emitted by RAISE commands. That was never more than a quick backwards-compatibility hack, and it's pretty silly in cases where the RAISE is nested in several levels of function. What's more, it violated our design theory that verbosity of error reports should be controlled on the client side not the server side. To alleviate the resulting noise increase, introduce a feature in libpq and psql whereby the CONTEXT field of messages can be suppressed, either always or only for non-error messages. Printing CONTEXT for errors only is now their default behavior. The actual code changes here are pretty small, but the effects on the regression test outputs are widespread. I had to edit some of the alternative expected outputs by hand; hopefully the buildfarm will soon find anything I fat-fingered. In passing, fix up (again) the output line counts in psql's various help displays. Add some commentary about how to verify them.

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.	10 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.	10 years ago
Peter Eisentraut	75f9d17638	Make Python tests more portable Newer Python versions randomize the hash seed for dictionaries, resulting in a random output order, which messes up the regression test diffs. Instead, use Python assert to compare the dictionaries with their expected value.	10 years ago
Tom Lane	91e79260f6	Remove no-longer-required function declarations. Remove a bunch of "extern Datum foo(PG_FUNCTION_ARGS);" declarations that are no longer needed now that PG_FUNCTION_INFO_V1(foo) provides that. Some of these were evidently missed in commit `e7128e8dbb`, but others were cargo-culted in in code added since then. Possibly that can be blamed in part on the fact that we'd not fixed relevant documentation examples, which I've now done.	10 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.	10 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
