* Support retaining data dirs on successful TAP testsPeter Eisentraut2017-09-05
| | | | | | | | | | | | | This moves the data directories from using temporary directories with randomness in the directory name to a static name, to make it easier to debug. The data directory will be retained if tests fail or the test code dies/exits with failure, and is automatically removed on the next make check. If the environment variable PG_TEST_NOCLEAN is defined, the data directories will be retained regardless of test or exit status. Author: Daniel Gustafsson <daniel@yesql.se>
* Rename "pg_xlog" directory to "pg_wal".Robert Haas2016-10-20
| | | | | | | | | | | | | | | | | | | | | "xlog" is not a particularly clear abbreviation for "write-ahead log", and it sometimes confuses users into believe that the contents of the "pg_xlog" directory are not critical data, leading to unpleasant consequences. So, rename the directory to "pg_wal". This patch modifies pg_upgrade and pg_basebackup to understand both the old and new directory layouts; the former is necessary given the purpose of the tool, while the latter merely avoids an unnecessary backward-compatibility break. We may wish to consider renaming other programs, switches, and functions which still use the old "xlog" naming to also refer to "wal". However, that's still under discussion, so let's do just this much for now. Discussion: CAB7nPqTeC-8+zux8_-4ZD46V7YPwooeFxgndfsq5Rg8ibLVm1A@mail.gmail.com Michael Paquier
* Remove unnecessary row ordering dependency in pg_rewind test suite.Tom Lane2015-12-24
| | | | | | | t/002_databases.pl was expecting to see a specific physical order of the rows in pg_database. I broke that in HEAD with commit 01e386a325549b77, but I'd say it's a pretty fragile test methodology in any case, so fix it in 9.5 as well.

* pg_rewind: Don't error if the two clusters are already on the same timelinePeter Eisentraut2015-12-11
| | | | | This previously resulted in an error and a nonzero exit status, but after discussion this should rather be a noop with a zero exit status.
* Refactor Perl test codeAlvaro Herrera2015-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix pg_rewind when pg_xlog is a symlink.Heikki Linnakangas2015-08-03
| | | | | | | | | | pg_xlog is often a symlink, typically to a different filesystem. Don't get confused and comlain about by that, and just always pretend that it's a normal directory, even if it's really a symlink. Also add a test case for this. Backpatch to 9.5.
* Improve logging of TAP tests.Heikki Linnakangas2015-07-09
| | | | | | | | | | | | | | | | | | | | | | 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.

* Shut down test servers after pg_rewind regression tests.Heikki Linnakangas2015-04-15
| | | | | | | | Now that the test servers are initialized twice in each .pl script, the single END block is not enough to stop them. Add a new clean_rewind_test function that is called at the end of each test. Michael Paquier
* Refactor and fix TAP tests of pg_rewindHeikki Linnakangas2015-04-13
| | | | | | | | | | | | | | | | | | * Don't pass arguments to prove, since that's not supported on perl 5.8 which is the minimum version supported by the TAP tests. Refactor the test files themselves to run the tests twice, in both local and remote mode. * Use eq rather than == for string comparison. This thinko caused the remote versions of the tests to never run. * Add "use strict" and "use warnings", and fix warnings that that produced. * Increase the delay after standby promotion, to make the tests more robust. * In remote mode, the connection string to the promoted standby was incorrect, leading to connection errors. Patch by Michael Paquier, to address Peter Eisentraut's report.
* Add pg_rewind, for re-synchronizing a master server after failback.Heikki Linnakangas2015-03-23
Earlier versions of this tool were available (and still are) on github. Thanks to Michael Paquier, Alvaro Herrera, Peter Eisentraut, Amit Kapila, and Satoshi Nagayasu for review.
