* Remove MSVC scriptsMichael Paquier2023-12-20
| | | | | | | | | | | | | | | | | This commit removes all the scripts located in src/tools/msvc/ to build PostgreSQL with Visual Studio on Windows, meson becoming the recommended way to achieve that. The scripts held some information that is still relevant with meson, information kept and moved to better locations. Comments that referred directly to the scripts are removed. All the documentation still relevant that was in install-windows.sgml has been moved to installation.sgml under a new subsection for Visual. All the content specific to the scripts is removed. Some adjustments for the documentation are planned in a follow-up set of changes.

* Remove distprepPeter Eisentraut2023-11-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A PostgreSQL release tarball contains a number of prebuilt files, in particular files produced by bison, flex, perl, and well as html and man documentation. We have done this consistent with established practice at the time to not require these tools for building from a tarball. Some of these tools were hard to get, or get the right version of, from time to time, and shipping the prebuilt output was a convenience to users. Now this has at least two problems: One, we have to make the build system(s) work in two modes: Building from a git checkout and building from a tarball. This is pretty complicated, but it works so far for autoconf/make. It does not currently work for meson; you can currently only build with meson from a git checkout. Making meson builds work from a tarball seems very difficult or impossible. One particular problem is that since meson requires a separate build directory, we cannot make the build update files like gram.h in the source tree. So if you were to build from a tarball and update gram.y, you will have a gram.h in the source tree and one in the build tree, but the way things work is that the compiler will always use the one in the source tree. So you cannot, for example, make any gram.y changes when building from a tarball. This seems impossible to fix in a non-horrible way. Second, there is increased interest nowadays in precisely tracking the origin of software. We can reasonably track contributions into the git tree, and users can reasonably track the path from a tarball to packages and downloads and installs. But what happens between the git tree and the tarball is obscure and in some cases non-reproducible. The solution for both of these issues is to get rid of the step that adds prebuilt files to the tarball. The tarball now only contains what is in the git tree (*). Getting the additional build dependencies is no longer a problem nowadays, and the complications to keep these dual build modes working are significant. And of course we want to get the meson build system working universally. This commit removes the make distprep target altogether. The make dist target continues to do its job, it just doesn't call distprep anymore. (*) - The tarball also contains the INSTALL file that is built at make dist time, but not by distprep. This is unchanged for now. The make maintainer-clean target, whose job it is to remove the prebuilt files in addition to what make distclean does, is now just an alias to make distprep. (In practice, it is probably obsolete given that git clean is available.)

* Bump minimum Perl version to 5.14John Naylor2022-09-14
| | | | | | | | | | | | | | | | | | | | The oldest vendor-shipped Perl in the buildfarm is 5.14.2, which is the last version that Debian Wheezy shipped. That OS is EOL, but we keep it running because there is no other convenient way to test certain non-mainstream 32-bit platforms. There is no bugfix in the 5.14.2 release that is required, and yet it's also not the latest minor release -- that would be 5.14.4. To clarify the situation, we have thus arranged the buildfarm to test 5.14.0. That allows configure scripts and documentation to state 5.14 without fine print. The MSVC build didn't check the version, since our previous minimum 5.8.3 was considered too old to check for on Windows. We will need a check for Windows sometime during the v16 cycle, but that could be rendered moot by the impending Meson conversion, so it seems safe to just document the requirement for now.

* Remove further unwanted linker flags from perl_embed_ldflagsPeter Eisentraut2022-08-23
| | | | | | | | | | | | | | | | | | Remove the contents of $Config{ldflags} from ExtUtils::Embed's ldopts, like we already do with $Config{ccdlflags}. Those flags are the choices of those who built the Perl installation, which are not necessarily appropriate for building PostgreSQL. What we really want from ldopts are the options identifying the location and name of the libperl library, but unfortunately it doesn't appear possible to get that separately from the other stuff. The motivation for this was to strip -mmacosx-version-min options. We already did something similar for the -arch option. Both of those are now covered by this more general approach.

* Adjust configure to insist on Perl version >= 5.8.3.Tom Lane2021-10-07
| | | | | | | | | | | | | | | | Previously it only checked for version >= 5.8.0, although the documentation has said that the minimum version is 5.8.3 since commit dea6ba939. Per the discussion leading up to that commit, I (tgl) left it that way intentionally because you could, at the time, do some bare-bones stuff with 5.8.0. But we aren't actually testing against anything older than 5.8.3, so who knows if that's still true. It's pretty unlikely that anyone would care anyway, so let's just make configure's version check match the docs.

* MSVC: Test whether 32-bit Perl needs -D_USE_32BIT_TIME_T.Noah Misch2017-12-08
| | | | | | | | | | | | | | | | | | | | | Commits 5a5c2feca3fd858e70ea348822595547e6fa6c15 and b5178c5d08ca59e30f9d9428fa6fdb2741794e65 introduced support for modern MSVC-built, 32-bit Perl, but they broke use of MinGW-built, 32-bit Perl distributions like Strawberry Perl and modern ActivePerl. Perl has no robust means to report whether it expects a -D_USE_32BIT_TIME_T ABI, so test this. Back-patch to 9.3 (all supported versions). The chief alternative was a heuristic of adding -D_USE_32BIT_TIME_T when $Config{gccversion} is nonempty. That banks on every gcc-built Perl using the same ABI. gcc could change its default ABI the way MSVC once did, and one could build Perl with gcc and the non-default ABI. The GNU make build system could benefit from a similar test, without which it does not support MSVC-built Perl. For now, just add a comment. Most users taking the special step of building Perl with MSVC probably build PostgreSQL with MSVC. Discussion: https://postgr.es/m/20171130041441.GA3161526@rfd.leadboat.com

* Absorb -D_USE_32BIT_TIME_T switch from Perl, if relevant.Tom Lane2017-08-14
| | | | | | | | | | | | | | | | | | | | | | | | Commit 3c163a7fc's original choice to ignore all #define symbols whose names begin with underscore turns out to be too simplistic. On Windows, some Perl installations are built with -D_USE_32BIT_TIME_T, and we must absorb that or we get the wrong result for sizeof(PerlInterpreter). This effectively re-reverts commit ef58b87df, which injected that symbol in a hacky way, making it apply to all of Postgres not just PL/Perl. More significantly, it did so on *all* 32-bit Windows builds, even when the Perl build to be used did not select this option; so that it fails to work properly with some newer Perl builds. By making this change, we would be introducing an ABI break in 32-bit Windows builds; but fortunately we have not used type time_t in any exported Postgres APIs in a long time. So it should be OK, both for PL/Perl itself and for third-party extensions, if an extension library is built with a different _USE_32BIT_TIME_T setting than the core code. Patch by me, based on research by Ashutosh Sharma and Robert Haas. Back-patch to all supported branches, as commit 3c163a7fc was.

* Further improve consistency of configure's program searching.Tom Lane2017-08-01
| | | | | | | | | | | | | | | | | | | | | Peter Eisentraut noted that commit 40b9f1921 had broken a configure behavior that some people might rely on: AC_CHECK_PROGS(FOO,...) will allow the search to be overridden by specifying a value for FOO on configure's command line or in its environment, but AC_PATH_PROGS(FOO,...) accepts such an override only if it's an absolute path. We had worked around that behavior for some, but not all, of the pre-existing uses of AC_PATH_PROGS by just skipping the macro altogether when FOO is already set. Let's standardize on that workaround for all uses of AC_PATH_PROGS, new and pre-existing, by wrapping AC_PATH_PROGS in a new macro PGAC_PATH_PROGS. While at it, fix a deficiency of the old workaround code by making sure we report the setting to configure's log. Eventually I'd like to improve PGAC_PATH_PROGS so that it converts non-absolute override inputs to absolute form, eg "PYTHON=python3" becomes, say, PYTHON = /usr/bin/python3. But that will take some nontrivial coding so it doesn't seem like a thing to do in late beta. Discussion: https://postgr.es/m/90a92a7d-938e-507a-3bd7-ecd2b4004689@2ndquadrant.com
* PL/Perl portability fix: absorb relevant -D switches from Perl.Tom Lane2017-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Perl documentation is very clear that stuff calling libperl should be built with the compiler switches shown by Perl's $Config{ccflags}. We'd been ignoring that up to now, and mostly getting away with it, but recent Perl versions contain ABI compatibility cross-checks that fail on some builds because of this omission. In particular the sizeof(PerlInterpreter) can come out different due to some fields being added or removed; which means we have a live ABI hazard that we'd better fix rather than continuing to sweep it under the rug. However, it still seems like a bad idea to just absorb $Config{ccflags} verbatim. In some environments Perl was built with a different compiler that doesn't even use the same switch syntax. -D switch syntax is pretty universal though, and absorbing Perl's -D switches really ought to be enough to fix the problem. Furthermore, Perl likes to inject stuff like -D_LARGEFILE_SOURCE and -D_FILE_OFFSET_BITS=64 into $Config{ccflags}, which affect libc ABIs on platforms where they're relevant. Adopting those seems dangerous too. It's unclear whether a build wherein Perl and Postgres have different ideas of sizeof(off_t) etc would work, or whether anyone would care about making it work. But it's dead certain that having different stdio ABIs in core Postgres and PL/Perl will not work; we've seen that movie before. Therefore, let's also ignore -D switches for symbols beginning with underscore. The symbols that we actually need to import should be the ones mentioned in perl.h's PL_bincompat_options stanza, and none of those start with underscore, so this seems likely to work. (If it turns out not to work everywhere, we could consider intersecting the symbols mentioned in PL_bincompat_options with the -D switches. But that will be much more complicated, so let's try this way first.) This will need to be back-patched, but first let's see what the buildfarm makes of it.

* Fix configure's incorrect version tests for flex and perl.Tom Lane2016-05-02
| | | | | | | | | | | | awk's equality-comparison operator is "==" not "=". We got this right in many places, but not in configure's checks for supported version numbers of flex and perl. It hadn't been noticed because unsupported versions are so old as to be basically extinct in the wild, and because the only consequence is whether or not a WARNING flies by during configure. Daniel Gustafsson noted the problem with respect to the test for flex, I found the other by reviewing other awk calls.
