Modern versions of msys2 have changed the treatment of "cmd /c" so that
the runtime will try to convert the switch to a native file path. This
patch adds a setting to inhibit that behaviour.

Backpatch to all live branches.
On msys2, 'uname -s' reports a string starting MSYS instead on MINGW
as happens on msys1. Treat these both the same way. This reverts
608a710195 in favor of a more general solution.
Backpatch to all live branches.
On master (after 700538) the old version's installed psql was used -
even when the old version might not actually be installed / might be
installed into a temporary directory. As commonly the case when just
executing make check for pg_upgrade, as $oldbindir is just the current
version's $bindir.
In the back branches, with --install specified, psql from the new
version's temporary installation was used, without --install (e.g for
NO_TEMP_INSTALL, cf 47b3c26642), the new version's installed psql was
used (which might or might not exist).

I blew the dust off a Bourne shell (file date 1996, yea verily) and
tried to run test.sh with it. It mostly worked, but I found that the
temp-directory creation code introduced by commit be76a6d39 was not
compatible, for a couple of reasons: this shell thinks "set -e" should
force an exit if a command within backticks fails, and it also thinks code
within braces should be executed by a sub-shell, meaning that variable
settings don't propagate back up to the parent shell. In view of Victor
Wagner's report that Solaris is still using pre-POSIX shells, seems like
we oughta make this case work. It's not like the code is any less
idiomatic this way; the prior coding technique appeared nowhere else.
(There is a remaining bash-ism here, which is that $RANDOM doesn't do
what the code hopes in non-bash shells. But the use of $$ elsewhere in
that path should be enough to ensure uniqueness and some amount of
randomness, so I think it's okay as-is.)
Back-patch to all supported branches, as the previous commit was.

Msys2's uname -s outputs a string beginning MSYS rather than MINGW as is
output by Msys. Allow either in pg_upgrade's test.sh.
Backpatch to all live branches.
Due to simplistic quoting and confusion of database names with conninfo
strings, roles with the CREATEDB or CREATEROLE option could escalate to
superuser privileges when a superuser next ran certain maintenance
commands. The new coding rule for PQconnectdbParams() calls, documented
at conninfo_array_parse(), is to pass expand_dbname=true and wrap
literal database names in a trivial connection string. Escape
zero-length values in appendConnStrVal(). Back-patch to 9.1 (all
supported versions).

This setting contains extra configuration for the temp instance, as used
in pg_regress' --temp-config flag.
Backpatch to 9.2 where test.sh was introduced.
POSIX does not specify the -q option, and many implementations do not
offer it. Don't bother changing the MSVC build system, because having
non-GNU diff on Windows is vanishingly unlikely. Back-patch to 9.2,
where this invocation was introduced.
SUSv2-era shells don't set the PWD variable, though anything more modern
does. In the buildfarm environment this could lead to test.sh executing
with PWD pointing to $HOME or another high-level directory, so that there
were conflicts between concurrent executions of the test in different
branch subdirectories. This appears to be the explanation for recent
intermittent failures on buildfarm members binturong and dingo (and might
well have something to do with the buildfarm script's failure to capture
log files from pg_upgrade tests, too).
To fix, just use `pwd` in place of $PWD. AFAICS test.sh is the only place
in our source tree that depended on $PWD. Back-patch to all versions
containing this script.
Per buildfarm. Thanks to Oskari Saarenmaa for diagnosing the problem.
Use SSPI authentication to allow connections exclusively from the OS
user that launched the test suite. This closes on Windows the
vulnerability that commit be76a6d39e
closed on other platforms. Users of "make installcheck" or custom test
harnesses can run "pg_regress --config-auth=DATADIR" to activate the
same authentication configuration that "make check" would use.
Back-patch to 9.0 (all supported versions).
Security: CVE-2014-0067
Any OS user able to access the socket can connect as the bootstrap
superuser and proceed to execute arbitrary code as the OS user running
the test. Protect against that by placing the socket in a temporary,
mode-0700 subdirectory of /tmp. The pg_regress-based test suites and
the pg_upgrade test suite were vulnerable; the $(prove_check)-based test
suites were already secure. Back-patch to 8.4 (all supported versions).
The hazard remains wherever the temporary cluster accepts TCP
connections, notably on Windows.
As a convenient side effect, this lets testing proceed smoothly in
builds that override DEFAULT_PGSOCKET_DIR. Popular non-default values
like /var/run/postgresql are often unwritable to the build user.

Any OS user able to access the socket can connect as the bootstrap

Attempts to run "make check" from a directory with a long name will now
fail. An alternative not sharing that problem was to place the socket
in a subdirectory of /tmp, but that is only secure if /tmp is sticky.
The PG_REGRESS_SOCK_DIR environment variable is available as a
workaround when testing from long directory paths.

I discovered the hard way that on some old shells, the locution
FOO="" unset FOO
does not behave the same as
FOO=""; unset FOO
and in fact leaves FOO set to an empty string. test.sh was inconsistently
spelling it different ways on adjacent lines.
This got broken relatively recently, in commit c737a2e56, so the lack of
field reports to date doesn't represent a lot of evidence that the problem
is rare.
The NetBSD shell apparently returns non-zero from an unset command if
the variable is already unset. This matters when, as in pg_upgrade's
test.sh, we are working under 'set -e'. To protect against this, we
first set the PG variables to an empty string before unsetting them
completely.
Error found on buildfarm member coypu, solution from Rémi Zara.
Previously, the port number used in this test script was hard-wired at
pg_upgrade's default of 50432; which is not so great because parallel build
runs might conflict. Commit 3d53173e20
removed this setting for the postmasters started by the script proper
(not by pg_upgrade), which didn't do anything to fix that problem and also
guaranteed a failure if there was a live postmaster at the build's default
port number. Instead, select a non-conflicting temporary port number in
the same way that pg_regress.c does. (Its method isn't entirely
bulletproof, but given the lack of complaints I'm not going to worry
about that today.)
In passing, unset MAKEFLAGS and MAKELEVEL to avoid problems with the
script's internal invocations of make, for the same reason pg_regress.c
does: it could cause problems in a parallel make.
This code was left over from when pg_upgrade paid attention to PGPORT.
Now it would only affects the regression test run before the test run of
pg_upgrade. You can still set PGPORT for that, but there is no reason
to have the test driver default it to 50432.
Windows sometimes gets upset if we rename a large directory and then try
to use the old name quickly, as seen in occasional buildfarm failures.
So we avoid that by building the old version in the intended
destination in the first place instead of renaming it, similar to the
change made for the same reason in commit b7f8465c.
This is now used by ecpg tests, and not clobbered by pg_upgrade
tests. This change won't affect anything that doesn't set this
environment variable, but will enable the buildfarm to control
exactly what port regression test installs will be running on,
and thus to detect possible rogue postmasters more easily.
Backpatch to release 9.2 where EXTRA_REGRESS_OPTS was first used.
On non-Windows machines, we use the Unix socket for connections to test
postmasters, so there is no need to create a TCP socket. Furthermore,
doing so causes failures due to port conflicts if two builds are carried
out concurrently on one machine. (If the builds are done in different
chroots, which is standard practice at least in Red Hat distros, there
is no risk of conflict on the Unix socket.) Suppressing the TCP socket
by setting listen_addresses to empty has long been standard practice
for pg_regress, and pg_upgrade knows about this too ... but pg_upgrade's
test.sh didn't get the memo.
Back-patch to 9.2, and also sync the 9.2 version of the script with HEAD
as much as practical.
Call pg_dumpall using -f switch instead of redirection, to avoid
writing the output in text mode and generating spurious carriage
returns. Remove to carriage return ignoring hack introduced by
commit e442b0f0c6.
Backpatch to 9.2.
It runs the regression tests, runs pg_upgrade on the populated
database, and compares the before and after dumps. While not actually
a cross-version upgrade, this does detect omissions and bugs in the
involved tools from time to time. It's also possible to do a
cross-version upgrade by manually supplying parameters.
