721856ff24 Remove distprep
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.)

The following programs are now hard build requirements in configure
(they were already required by meson.build):

- bison
- flex
- perl

eab2d3147e Use --strip-unneeded when stripping static libraries with GNU strip.
We've long used "--strip-unneeded" for shared libraries but plain
"-x" for static libraries when stripping symbols with GNU strip.
There doesn't seem to be any really good reason for that though,
since --strip-unneeded produces smaller output (as "-x" alone
does not remove debug symbols).  Moreover it seems that
llvm-strip, although it identifies as GNU strip, misbehaves when
given "-x" for this purpose.  It's unclear whether that's
intentional or a bug in llvm-strip, but in any case it seems like
changing to use --strip-unneeded in all cases should be a win.

Note that this doesn't change our behavior when dealing with
non-GNU strip.

Per gripes from Ed Maste and Palle Girgensohn.  Back-patch,
in case anyone wants to use llvm-strip with stable branches.

b086a47a27 Bump minimum version of Bison to 2.3
Since the retirement of some older buildfarm members, the oldest Bison
that gets regular testing is 2.3. MacOS ships that version, and will
continue doing so for the forseeable future because of Apple's policy
regarding GPLv3. While Mac users could use a package manager to install
a newer version, there is no compelling reason to force them do so at
this time.

4b0e37faaf Remove configure's check for rl_completion_append_character.
The comment for PGAC_READLINE_VARIABLES says "Readline versions < 2.1
don't have rl_completion_append_character".  It seems certain that such
versions are extinct in the wild, though; for sure there are none in the
buildfarm.  Libedit has had this variable for at least twenty years too.
Also, tab-complete.c's behavior without it is quite unfriendly, since
we'll emit a space even when completion fails; but we've had no
complaints about that.

Therefore, let's assume this variable is always there, and drop the
configure check to save a few build cycles.

c32704441d Add configure probe for rl_completion_suppress_quote.
I had supposed that all versions of Readline that have filename
quoting hooks also have the rl_completion_suppress_quote variable.
But it seems OpenBSD managed to find a version someplace that does
not, so we'll have to expend a separate configure probe for that.

(Light testing suggests that this version also lacks the bugs that
make it necessary to frob that variable.  Hooray!)

Per buildfarm.

cd69ec66c8 Improve psql's tab completion for filenames.
The Readline library contains a fair amount of knowledge about how to
tab-complete filenames, but it turns out that that doesn't work too well
unless we follow its expectation that we use its filename quoting hooks
to quote and de-quote filenames.  We were trying to do such quote handling
within complete_from_files(), and that's still what we have to do if we're
using libedit, which lacks those hooks.  But for Readline, it works a lot
better if we tell Readline that single-quote is a quoting character and
then provide hooks that know the details of the quoting rules for SQL
and psql meta-commands.

Hence, resurrect the quoting hook functions that existed in the original
version of tab-complete.c (and were disabled by commit f6689a328 because
they "didn't work so well yet"), and whack on them until they do seem to
work well.

Notably, this fixes bug #16059 from Steven Winfield, who pointed out
that the previous coding would strip quote marks from filenames in SQL
COPY commands, even though they're syntactically necessary there.
Now, we not only don't do that, but we'll add a quote mark when you
tab-complete, even if you didn't type one.

Getting this to work across a range of libedit versions (and, to a
lesser extent, libreadline versions) was depressingly difficult.
It will be interesting to see whether the new regression test cases
pass everywhere in the buildfarm.

Some future patch might try to handle quoted SQL identifiers with
similar explicit quoting/dequoting logic, but that's for another day.

Patch by me, reviewed by Peter Eisentraut.

29b3ac7546 configure: More use of AC_ARG_VAR
AC_ARG_VAR is necessary if an environment variable influences a
configure result that is then used by other tests that are cached.
With AC_ARG_VAR, a change in the variable is detected on subsequent
configure runs and the user is then advised to remove the cache.

This adds AC_ARG_VAR calls for: MSGFMT, PERL, PYTHON, TCLSH, XML2_CONFIG

b21c569cea Further improve consistency of configure's program searching.
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.

40b9f19217 Record full paths of programs sought by "configure".
Previously we had a mix of uses of AC_CHECK_PROG[S] and AC_PATH_PROG[S].
The only difference between those macros is that the latter emits the
full path to the program it finds, eg "/usr/bin/prove", whereas the
former emits just "prove".  Let's standardize on always emitting the
full path; this is better for documentation of the build, and it might
prevent some types of failures if later build steps are done with
a different PATH setting.

I did not touch the AC_CHECK_PROG[S] calls in ax_pthread.m4 and
ax_prog_perl_modules.m4.  There seems no need to make those diverge from
upstream, since we do not record the programs sought by the former, while
the latter's call to AC_CHECK_PROG(PERL,...) will never be reached.

7d7b129277 Fix configure's incorrect version tests for flex and perl.
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.

5dd41f3574 Remove maintainer-check target, fold into normal build
make maintainer-check was obscure and rarely called in practice, and
many breakages were missed.  Fold everything that make maintainer-check
used to do into the normal build.  Specifically:

- Call duplicate_oids when genbki.pl is called.

- Check for tabs in SGML files when the documentation is built.

- Run msgfmt with the -c option during the regular build.  Add an
  additional configure check to see whether we are using the GNU
  version.  (make maintainer-check probably used to fail with non-GNU
  msgfmt.)

Keep maintainer-check as around as phony target for the time being in
case anyone is calling it.  But it won't do anything anymore.
