This makes it easier to relate the temporary data dirs to each node in
a test script.

Commit 7132810c (Retain tempdirs for failed tests) used Test::More's
is_passing method, but that was added in Test::More 0.89_01 which is
sometime later than Perl 5.10.1. Popular platforms such as RHEL6 don't
have that, nevermind some of our older dinosaurs. Do it the hard way.

For unclear reasons, this function doesn't always read the expected data
in some old Perl versions. Rewriting it to avoid use of ARGV seems to
dodge the problem, and this version is clearer anyway if you ask me.
In passing, also improve error message in adjacent append_to_file function.
This way, existing .gitignore entries and makefile clean actions will
automatically apply to the tempdir, should it survive a TAP test run
(which can happen if the user control-C's out of the run, for example).
Michael Paquier, per a complaint from me
The original code was a bit clunky; make it more amenable for further
reuse by creating a new Perl package PostgresNode, which is an
object-oriented representation of a single server, with some support
routines such as init, start, stop, psql. This serves as a better basis
on which to build further test code, and enables writing tests that use
more than one server without too much complication.
This commit modifies a lot of the existing test files, mostly to remove
explicit calls to system commands (pg_ctl) replacing them with method
calls of a PostgresNode object. The result is quite a bit more
straightforward.
Also move some initialization code to BEGIN and INIT blocks instead of
having it straight in as top-level code.
This commit also introduces package RecursiveCopy so that we can copy
whole directories without having to depend on packages that may not be
present on vanilla Perl 5.8 installations.
I also ran perltidy on the modified files, which changes some code sites
that are not otherwise touched by this patch. I tried to avoid this,
but it ended up being more trouble than it's worth.

Most suites already did so via start_test_server(), but the pg_rewind,
pg_ctl and pg_controldata suites ran a postmaster or initdb with fsync
enabled. This halves the pg_rewind suite's runtime on buildfarm member
tern. It makes tern and that machine's other buildfarm members less
vulnerable to noise failures from postmaster startup overrunning the 60s
pg_ctl timeout. Back-patch to 9.5, where pg_rewind was introduced.
The Msys DTK perl, which is required to run TAP tests under Msys as a
native perl won't recognize the correct virtual paths, has its osname
recorded in the Config module as 'msys' instead of 'MSWin32'. To avoid
having to repeat the test a variable is created that is true iff the
osname is either of these values, and is then used everywhere that
matters.
On Windows, use listen_address=127.0.0.1 to allow TCP connections. We were
already using "pg_regress --config-auth" to set up HBA appropriately. The
standard_initdb helper function now sets up the server's
unix_socket_directories or listen_addresses in the config file, so that
they don't need to be specified in the pg_ctl command line anymore. That
way, the pg_ctl invocations in test programs don't need to differ between
Windows and Unix.
Add another helper function to configure the server's pg_hba.conf to allow
replication connections. The configuration is done similarly to "pg_regress
--config-auth": trust on domain sockets on Unix, and SSPI authentication on
Windows.
Replace calls to "cat" and "touch" programs with built-in perl code, as
those programs don't normally exist on Windows.
Add instructions in the docs on how to install IPC::Run on Windows. Adjust
vcregress.pl to not replace PERL5LIB completely in vcregress.pl, because
otherwise cannot install IPC::Run in a non-standard location easily.

This option specifies a replication slot for WAL streaming (-X stream),
so that there can be continuous replication slot use between WAL
streaming during the base backup and the start of regular streaming
replication.

Create a log file for each test run. Stdout and stderr of the test script,
as well as any subprocesses run as part of the test, are redirected to
the log file. This makes it a lot easier to debug test failures. Also print
the test output (ok 12 - ... messages) to the log file, and the command
line of any external programs executed with the system_or_bail and run_log
functions. This makes it a lot easier to debug failing tests.
Modify some of the pg_ctl and other command invocations to not use 'silent'
or 'quiet' options, and don't redirect output to /dev/null, so that you get
all the information in the log instead.
In the passing, construct some command lines in a way that works if $tempdir
contains quote-characters. I haven't systematically gone through all of
them or tested that, so I don't know if this is enough to make that work.
pg_rewind tests had a custom mechanism for creating a similar log file. Use
the new generic facility instead.
Michael Paquier and me.
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).

Bug Fixes
* subtest() should not fail if $? is non-zero. (Aaron Crane)
Unset environment variables that control message language, so that we
can compare some program output with expected strings. This is very
similar to what pg_regress does.
Creating the Unix-domain socket in the build directory can run into
name-length limitations. Therefore, create the socket file in the
default temporary directory of the operating system. Keep the temporary
data directory etc. in the build tree.
