This checks that certain I/O-related Perl functions properly check
their return value. Some parts of the PostgreSQL code had been a bit
sloppy about that. The new perlcritic warnings are fixed here. I
didn't design any beautiful error messages, mostly just used "or die
$!", which mostly matches existing code, and also this is
developer-level code, so having the system error plus source code
reference should be ok.
Initially, we only activate this check for a subset of what the
perlcritic check would warn about. The effective list is
chmod flock open read rename seek symlink system
The initial set of functions is picked because most existing code
already checked the return value of those, so any omissions are
probably unintended, or because it seems important for test
correctness.
The actual perlcritic configuration is written as an exclude list.
That seems better so that we are clear on what we are currently not
checking. Maybe future patches want to investigate checking some of
the other functions. (In principle, we might eventually want to check
all of them, but since this is test and build support code, not
production code, there are probably some reasonable compromises to be
made.)

Most callers of strerror() are removed from the backend code. The
remaining callers require special handling with a saved errno from a
previous system call. The frontend code still needs strerror() where
error states need to be handled outside of fprintf.
Note that pg_regress is not changed to use %m as the TAP output may
clobber errno, since those functions call fprintf() and friends before
evaluating the format string.
Support for %m in src/port/snprintf.c has been added in d6c55de1f9,
hence all the stable branches currently supported include it.

There are a lot of Perl scripts in the tree, mostly code generation
and TAP tests. Occasionally, these scripts produce warnings. These
are probably always mistakes on the developer side (true positives).
Typical examples are warnings from genbki.pl or related when you make
a mess in the catalog files during development, or warnings from tests
when they massage a config file that looks different on different
hosts, or mistakes during merges (e.g., duplicate subroutine
definitions), or just mistakes that weren't noticed because there is a
lot of output in a verbose build.
This changes all warnings into fatal errors, by replacing
use warnings;
by
use warnings FATAL => 'all';
in all Perl files.

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

Since C99, there can be a trailing comma after the last value in an
enum definition. A lot of new code has been introducing this style on
the fly. Some new patches are now taking an inconsistent approach to
this. Some add the last comma on the fly if they add a new last
value, some are trying to preserve the existing style in each place,
some are even dropping the last comma if there was one. We could
nudge this all in a consistent direction if we just add the trailing
commas everywhere once.
I omitted a few places where there was a fixed "last" value that will
always stay last. I also skipped the header files of libpq and ecpg,
in case people want to use those with older compilers. There were
also a small number of cases where the enum type wasn't used anywhere

so I left those alone.

One file per line seems best. We already did this in some cases.
This adopts the same format everywhere (except in some cases where the
list reasonably fits on one line).
Some callers didn't check the return value of pclose() or
ClosePipeStream() correctly. Either they didn't check it at all or
they treated it like the return of fclose().
The correct way is to first check whether the return value is -1, and
then report errno, and then check the return value like a result from
system(), for which we already have wait_result_to_str() to make it
simpler. To make this more compact, expand wait_result_to_str() to
also handle -1 explicitly.

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.

This commit changes the following code paths to do direct system calls
to some WIN32 functions rather than loading them from an external
library, shaving some code in the process:
- Creation of restricted tokens in pg_ctl.c, introduced by a25cd81.
- QuerySecurityContextToken() in auth.c for SSPI authentication in the
backend, introduced in d602592.
- CreateRestrictedToken() in src/common/. This change is similar to the
case of pg_ctl.c.
Most of these functions were loaded rather than directly called because,
as mentioned in the code comments, MinGW headers were not declaring
them. I have double-checked the recent MinGW code, and all the
functions changed here are declared in its headers, so this change
should be safe. Note that I do not have a MinGW environment at hand so
I have not tested it directly, but that MSVC was fine with the change.
The buildfarm will tell soon enough if this change is appropriate or not
for a much broader set of environments.
A few code paths still use GetProcAddress() to load some functions:
- LDAP authentication for ldap_start_tls_sA(), where I am not confident
that this change would work.
- win32env.c and win32ntdll.c where we have a per-MSVC version
dependency for the name of the library loaded.
- crashdump.c for MiniDumpWriteDump() and EnumDirTree(), where direct
calls were not able to work after testing.

More than twenty years ago (79fcde48b), we hacked the postmaster
to avoid a core-dump on systems that didn't support fflush(NULL).
We've mostly, though not completely, hewed to that rule ever since.
But such systems are surely gone in the wild, so in the spirit of
cleaning out no-longer-needed portability hacks let's get rid of
multiple per-file fflush() calls in favor of using fflush(NULL).
Also, we were fairly inconsistent about whether to fflush() before
popen() and system() calls. While we've received no bug reports
about that, it seems likely that at least some of these call sites
are at risk of odd behavior, such as error messages appearing in
an unexpected order. Rather than expend a lot of brain cells
figuring out which places are at hazard, let's just establish a
uniform coding rule that we should fflush(NULL) before these calls.
A no-op fflush() is surely of trivial cost compared to launching
a sub-process via a shell; while if it's not a no-op then we likely
need it.

While I still think the basic idea is attractive, we need to sort

manually fix its oversight, let's change to using "$(wildcard *.c)"
in all these nls.mk files.
Many of these files also have manual references to some *.c files
in other directories, most often src/common/. Perhaps we should try
to improve that situation too; but it's a bit less clear how, so for

This moves the list of available languages from nls.mk into a separate
file called po/LINGUAS. Advantages:
- It keeps the parts notionally managed by programmers (nls.mk)
separate from the parts notionally managed by translators (LINGUAS).
- It's the standard practice recommended by the Gettext manual
nowadays.
- The Meson build system also supports this layout (and of course
doesn't know anything about our custom nls.mk), so this would enable
sharing the list of languages between the two build systems.

The previous minimal runtime version was either Windows Vista when

Windows 10 is the most modern version supported by Microsoft, and per

"pg_ctl stop/restart" checked that the postmaster PID is valid just
once, as a side-effect of sending the stop signal, and then would
wait-till-timeout for the postmaster.pid file to go away. This
neglects the case wherein the postmaster dies uncleanly after we
signal it. Similarly, once "pg_ctl promote" has sent the signal,
it'd wait for the corresponding on-disk state change to occur
even if the postmaster dies.
I'm not sure how we've managed not to notice this problem, but it
seems to explain slow execution of the 017_shm.pl test script on AIX
since commit 4fdbf9af5, which added a speculative "pg_ctl stop" with
the idea of making real sure that the postmaster isn't there. In the
test steps that kill-9 and then restart the postmaster, it's possible
to get past the initial signal attempt before kill() stops working
for the doomed postmaster. If that happens, pg_ctl waited till
PGCTLTIMEOUT before giving up ... and the buildfarm's AIX members
have that set very high.
To fix, include a "kill(pid, 0)" test (similar to what
postmaster_is_alive uses) in these wait loops, so that we'll
give up immediately if the postmaster PID disappears.
While here, I chose to refactor those loops out of where they were.
do_stop() and do_restart() can perfectly well share one copy of the
wait-for-stop loop, and it seems desirable to put a similar function
beside that for wait-for-promote.
Back-patch to all supported versions, since pg_ctl's wait logic
is substantially identical in all, and we're seeing the slow test
behavior in all branches.

"jsonlog" is a new value that can be added to log_destination to provide
logs in the JSON format, with its output written to a file, making it
the third type of destination of this kind, after "stderr" and
"csvlog". The format is convenient to feed logs to other applications.
There is also a plugin external to core that provided this feature using
the hook in elog.c, but this had to overwrite the output of "stderr" to
work, so being able to do both at the same time was not possible. The
files generated by this log format are suffixed with ".json", and use
the same rotation policies as the other two formats depending on the
backend configuration.
This takes advantage of the refactoring work done previously in ac7c807,
bed6ed3, 8b76f89 and 2d77d83 for the backend parts, and 72b76f7 for the
TAP tests, making the addition of any new file-based format rather
straight-forward.

The five modules in our TAP test framework all had names in the top
level namespace. This is unwise because, even though we're not
exporting them to CPAN, the names can leak, for example if they are
exported by the RPM build process. We therefore move the modules to the
PostgreSQL::Test namespace. In the process PostgresNode is renamed to
Cluster, and TestLib is renamed to Utils. PostgresVersion becomes simply
PostgreSQL::Version, to avoid possible confusion about what it's the
version of.

Incrementing the level of the call stack reported is useful for
debugging purposes as it allows to control which part of the test is
exactly failing, especially if a test is structured with subroutines
that call routines from Test::More.
This adds more incrementations of $Test::Builder::Level where debugging
gets improved (for example it does not make sense for some paths like
pg_rewind where long subroutines are used).
A note is added to src/test/perl/README about that, based on a
suggestion from Andrew Dunstan and a wording coming from both of us.
Usage of Test::Builder::Level has spread in 12, so a backpatch down to
this version is done.

These are added in the existing tests of pg_ctl for log rotation, that
already tested stderr. The same amount of coverage is added for csvlog:
- Checks for pg_current_logfile().
- Log rotation with expected file name.
- Log contents generated.
This test is refactored to minimize the amount of work required to add
tests for new log formats, easing some upcoming work.

Previously pgwin32_is_service() would falsely return true when postgres is
started from somewhere within a service, but not as a service. That is
e.g. always the case with windows docker containers, which some CI services
use to run windows tests in.
When postgres falsely thinks its running as a service, no messages are
writting to stdout / stderr. That can be very confusing and causes a few tests
to fail.
To fix additionally check if stderr is invalid in pgwin32_is_service(). For
that to work in backend processes, pg_ctl is changed to pass down handles so
that postgres can do the same check (otherwise "default" handles are created).
While this problem exists in all branches, there have been no reports by
users, the prospective CI usage currently is only for master, and I am not a
windows expert. So doing the change in only master for now seems the sanest
approach.

Replace fixed-length command buffers with psprintf() calls. We didn't
have anything as convenient as psprintf() when this code was written,
but now that we do, there's little reason for the limitation to
stand. Removing it eliminates some corner cases where (for example)
starting the postmaster with a whole lot of options fails.
Most individual file names that pg_ctl deals with are still restricted
to MAXPGPATH, but we've seldom had complaints about that limitation
so long as it only applies to one filename.
Back-patch to all supported branches.
