Andres Freund	902ab2fcef	meson: Add windows resource files ... The generated resource files aren't exactly the same ones as the old buildsystems generate. Previously "InternalName" and "OriginalFileName" were mostly wrong / not set (despite being required), but that was hard to fix in at least the make build. Additionally, the meson build falls back to a "auto-generated" description when not set, and doesn't set it in a few cases - unlikely that anybody looks at these descriptions in detail.

Andres Freund	e6927270cd	meson: Add initial version of meson based build system ... Autoconf is showing its age, fewer and fewer contributors know how to wrangle it. Recursive make has a lot of hard to resolve dependency issues and slow incremental rebuilds. Our home-grown MSVC build system is hard to maintain for developers not using Windows and runs tests serially. While these and other issues could individually be addressed with incremental improvements, together they seem best addressed by moving to a more modern build system. After evaluating different build system choices, we chose to use meson, to a good degree based on the adoption by other open source projects. We decided that it's more realistic to commit a relatively early version of the new build system and mature it in tree. This commit adds an initial version of a meson based build system. It supports building postgres on at least AIX, FreeBSD, Linux, macOS, NetBSD, OpenBSD, Solaris and Windows (however only gcc is supported on aix, solaris). For Windows/MSVC postgres can now be built with ninja (faster, particularly for incremental builds) and msbuild (supporting the visual studio GUI, but building slower). Several aspects (e.g. Windows rc file generation, PGXS compatibility, LLVM bitcode generation, documentation adjustments) are done in subsequent commits requiring further review. Other aspects (e.g. not installing test-only extensions) are not yet addressed. When building on Windows with msbuild, builds are slower when using a visual studio version older than 2019, because those versions do not support MultiToolTask, required by meson for intra-target parallelism. The plan is to remove the MSVC specific build system in src/tools/msvc soon after reaching feature parity. However, we're not planning to remove the autoconf/make build system in the near future. Likely we're going to keep at least the parts required for PGXS to keep working around until all supported versions build with meson. Some initial help for postgres developers is at https://wiki.postgresql.org/wiki/Meson With contributions from Thomas Munro, John Naylor, Stone Tickle and others.

John Naylor	4eec2e03c3	Be more careful to avoid including system headers after perl.h ... Commit 121d2d3d70 included simd.h into pg_wchar.h. This caused a problem on Windows, since Perl has "#define free" (referring to globals), which breaks the Windows' header. To fix, move the static inline function definitions from plperl_helpers.h, into plperl.h, where we already document the necessary inclusion order. Since those functions were the only reason for the existence of plperl_helpers.h, remove it.

Tom Lane	a57d312a77	Support infinity and -infinity in the numeric data type. ... Add infinities that behave the same as they do in the floating-point data types. Aside from any intrinsic usefulness these may have, this closes an important gap in our ability to convert floating values to numeric and/or replace float-based APIs with numeric. The new values are represented by bit patterns that were formerly not used (although old code probably would take them for NaNs). So there shouldn't be any pg_upgrade hazard.

Andres Freund	01368e5d9d	Split all OBJS style lines in makefiles into one-line-per-entry style. ... When maintaining or merging patches, one of the most common sources for conflicts are the list of objects in makefiles. Especially when the split across lines has been changed on both sides, which is somewhat common due to attempting to stay below 80 columns, those conflicts are unnecessarily laborious to resolve. By splitting, and alphabetically sorting, OBJS style lines into one object per line, conflicts should be less frequent, and easier to resolve when they still occur.

Amit Kapila	7e735035f2	Make the order of the header file includes consistent in contrib modules. ... The basic rule we follow here is to always first include 'postgres.h' or 'postgres_fe.h' whichever is applicable, then system header includes and then Postgres header includes.  In this, we also follow that all the Postgres header includes are in order based on their ASCII value.  We generally follow these rules, but the code has deviated in many places.

Tom Lane	032627ee78	Clean up PL/Perl's handling of the _() macro. ... Perl likes to redefine the _() macro: #ifdef CAN_PROTOTYPE #define _(args) args #else ... There was lots not to like about the way we dealt with this before: 1. Instead of taking care of the conflict centrally in plperl.h, we expected every one of its ever-growing number of includers to do so. This is duplicative and error-prone in itself, plus it means that plperl.h fails to meet the expectation of being compilable standalone, resulting in macro-redefinition warnings in cpluspluscheck. 2. We left _() with its Perl definition, meaning that if someone tried to use it in any Perl-related extension, it would silently fail to provide run-time translation. I don't see any live bugs of this ilk, but it's clearly a hard-to-notice bug waiting to happen. So fix that by centralizing the cleanup logic, making it match what we're already doing for other macro conflicts with Perl. Since we only expect plperl.h to be included by extensions not core code, we should redefine _() as dgettext() not gettext().	6 years ago
Tom Lane	e74dd00f53	Still further rethinking of build changes for macOS Mojave. ... To avoid the sorts of problems complained of by Jakob Egger, it'd be best if configure didn't emit any references to the sysroot path at all. In the case of PL/Tcl, we can do that just by keeping our hands off the TCL_INCLUDE_SPEC string altogether. In the case of PL/Perl, we need to substitute -iwithsysroot for -I in the compile commands, which is easily handled if we change to using a configure output variable that includes the switch not only the directory name. Since PL/Tcl and PL/Python already do it like that, this seems like good consistency cleanup anyway. Hence, this replaces the advice given to Perl-related extensions in commit 5e2217131; instead of writing "-I$(perl_archlibexp)/CORE", they should just write "$(perl_includespec)". (The old way continues to work, but not on recent macOS.) It's still the case that configure needs to be aware of the sysroot path internally, but that's cleaner than what we had before. As before, back-patch to all supported versions. Discussion: https://postgr.es/m/20840.1537850987@sss.pgh.pa.us	7 years ago
Tom Lane	5e22171310	Make some fixes to allow building Postgres on macOS 10.14 ("Mojave"). ... Apple's latest rearrangements of the system-supplied headers have broken building of PL/Perl and PL/Tcl. The only practical way to fix PL/Tcl is to start using the "-isysroot" compiler flag to point to SDK-supplied headers, as Apple expects. We must also start distinguishing where to find Perl's headers from where to find its shared library; but that seems like good cleanup anyway. Extensions that formerly did something like -I$(perl_archlibexp)/CORE should now do -I$(perl_includedir)/CORE instead. perl_archlibexp is still the place to look for libperl.so, though. If for some reason you don't like the default -isysroot setting, you can override that by setting PG_SYSROOT in configure's arguments. I don't currently think people would need to do so, unless maybe for cross-version build purposes. In addition, teach configure where to find tclConfig.sh. Our traditional method of searching $auto_path hasn't worked for the last couple of macOS releases, and it now seems clear that Apple's not going to change that. The workaround of manually specifying --with-tclconfig was annoying already, but Mojave's made it a lot more so because the sysroot path now has to be included as well. Let's just wire the knowledge into configure instead. To avoid breaking builds against non-default Tcl installations (e.g. MacPorts) wherein the $auto_path method probably still works, arrange to try the additional case only after all else has failed. Back-patch to all supported versions, since at least the buildfarm cares about that. The changes are set up to not do anything on macOS releases that are old enough to not have functional sysroot trees.	7 years ago
Alvaro Herrera	f2c587067a	Rethink how to get float.h in old Windows API for isnan/isinf ... We include <float.h> in every place that needs isnan(), because MSVC used to require it. However, since MSVC 2013 that's no longer necessary (cf. commit cec8394b5c), so we can retire the inclusion to a version-specific stanza in win32_port.h, where it doesn't need to pollute random .c files. The header is of course still needed in a few places for other reasons. I (Álvaro) removed float.h from a few more files than in Emre's original patch. This doesn't break the build in my system, but we'll see what the buildfarm has to say about it all.

Tom Lane	1731e3741c	Fix excessive enreferencing in jsonb-to-plperl transform. ... We want, say, 2 to be transformed as 2, not \\2 which is what the original coding produced. Perl's standard seems to be to add an RV wrapper only for hash and array SVs, so do it like that. This was missed originally because the test cases only checked what came out of a round trip back to SQL, and the strip-all-dereferences loop at the top of SV_to_JsonbValue hides the extra refs from view. As a better test, print the Perl value with Data::Dumper, like the hstore_plperlu tests do. While we can't do that in the plperl test, only plperlu, that should be good enough because this code is the same for both PLs. But also add a simplistic test for extra REFs, which we can do in both. That strip-all-dereferences behavior is now a bit dubious; it's unlike what happens for other Perl-to-SQL conversions. However, the best thing to do seems to be to leave it alone and make the other conversions act similarly. That will be done separately.

Tom Lane	331b2369c0	Fix platform and Perl-version dependencies in new jsonb_plperl code. ... Testing SvTYPE() directly is more fraught with problems than one might think, because depending on context Perl might be storing a scalar value in one of several forms, eg both numeric and string values. This resulted in Perl-version-dependent buildfarm test failures. Instead use the SvTYPE test only to distinguish non-scalar cases (AV, HV, NULL). Disambiguate scalars by testing SvIOK, SvNOK, then SvPOK. This creates a preference order for how we will resolve cases where the value is available in more than one form, which seems fine to me. Furthermore, because we're now dealing directly with a "double" value in the SvNOK case, we can get rid of an inadequate and unportable string-comparison test for infinities, and use isinf() instead. (We do need some additional #include and "-lm" infrastructure to use that in a contrib module, per prior experiences.) In passing, prevent the regression test results from depending on DROP CASCADE order; I've not seen that malfunction, but it's trouble waiting to happen.

Tom Lane	dddfc4cb2e	Prevent accidental linking of system-supplied copies of libpq.so etc. ... We were being careless in some places about the order of -L switches in link command lines, such that -L switches referring to external directories could come before those referring to directories within the build tree. This made it possible to accidentally link a system-supplied library, for example /usr/lib/libpq.so, in place of the one built in the build tree. Hilarity ensued, the more so the older the system-supplied library is. To fix, break LDFLAGS into two parts, a sub-variable LDFLAGS_INTERNAL and the main LDFLAGS variable, both of which are "recursively expanded" so that they can be incrementally adjusted by different makefiles. Establish a policy that -L switches for directories in the build tree must always be added to LDFLAGS_INTERNAL, while -L switches for external directories must always be added to LDFLAGS. This is sufficient to ensure a safe search order. For simplicity, we typically also put -l switches for the respective libraries into those same variables. (Traditional make usage would have us put -l switches into LIBS, but cleaning that up is a project for another day, as there's no clear need for it.) This turns out to also require separating SHLIB_LINK into two variables, SHLIB_LINK and SHLIB_LINK_INTERNAL, with a similar rule about which switches go into which variable. And likewise for PG_LIBS. Although this change might appear to affect external users of pgxs.mk, I think it doesn't; they shouldn't have any need to touch the _INTERNAL variables. In passing, tweak src/common/Makefile so that the value of CPPFLAGS recorded in pg_config lacks "-DFRONTEND" and the recorded value of LDFLAGS lacks "-L../../../src/common". Both of those things are mistakes, apparently introduced during prior code rearrangements, as old versions of pg_config don't print them. In general we don't want anything that's specific to the src/common subdirectory to appear in those outputs. This is certainly a bug fix, but in view of the lack of field complaints, I'm unsure whether it's worth the risk of back-patching. In any case it seems wise to see what the buildfarm makes of it first. Discussion: https://postgr.es/m/25214.1522604295@sss.pgh.pa.us	7 years ago
