Robert Haas	9c08aea6a3	Add new block-by-block strategy for CREATE DATABASE. ... Because this strategy logs changes on a block-by-block basis, it avoids the need to checkpoint before and after the operation. However, because it logs each changed block individually, it might generate a lot of extra write-ahead logging if the template database is large. Therefore, the older strategy remains available via a new STRATEGY parameter to CREATE DATABASE, and a corresponding --strategy option to createdb. Somewhat controversially, this patch assembles the list of relations to be copied to the new database by reading the pg_class relation of the template database. Cross-database access like this isn't normally possible, but it can be made to work here because there can't be any connections to the database being copied, nor can it contain any in-doubt transactions. Even so, we have to use lower-level interfaces than normal, since the table scan and relcache interfaces will not work for a database to which we're not connected. The advantage of this approach is that we do not need to rely on the filesystem to determine what ought to be copied, but instead on PostgreSQL's own knowledge of the database structure. This avoids, for example, copying stray files that happen to be located in the source database directory. Dilip Kumar, with a fairly large number of cosmetic changes by me.

Peter Eisentraut	f2553d4306	Add option to use ICU as global locale provider ... This adds the option to use ICU as the default locale provider for either the whole cluster or a database. New options for initdb, createdb, and CREATE DATABASE are used to select this. Since some (legacy) code still uses the libc locale facilities directly, we still need to set the libc global locale settings even if ICU is otherwise selected. So pg_database now has three locale-related fields: the existing datcollate and datctype, which are always set, and a new daticulocale, which is only set if ICU is selected. A similar change is made in pg_collation for consistency, but in that case, only the libc-related fields or the ICU-related field is set, never both.

Daniel Gustafsson	549ec201d6	Replace Test::More plans with done_testing ... Rather than doing manual book keeping to plan the number of tests to run in each TAP suite, conclude each run with done_testing() summing up the the number of tests that ran. This removes the need for maintaning and updating the plan count at the expense of an accurate count of remaining during the test suite runtime. This patch has been discussed a number of times, often in the context of other patches which updates tests, so a larger number of discussions can be found in the archives.

Michael Paquier	70bfc5ae53	Add test for copy of shared dependencies from template database ... As 98ec35b has proved, there has never been any coverage in this area of the code. This commit adds a new TAP test with a template database that includes a small set of shared dependencies copied to a new database. The test is added in createdb, where we have never tested that -T generates a query with TEMPLATE, either.

Andrew Dunstan	b3b4d8e68a	Move Perl test modules to a better namespace ... 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.

Andrew Dunstan	201a76183e	Unify PostgresNode's new() and get_new_node() methods ... There is only one constructor now for PostgresNode, with the idiomatic name 'new'. The method is not exported by the class, and must be called as "PostgresNode->new('name',[args])". All the TAP tests that use PostgresNode are modified accordingly. Third party scripts will need adjusting, which is a fairly mechanical process (I just used a sed script).	4 years ago

Tom Lane	9ffe227837	Adjust createdb TAP tests to work on recent OpenBSD. ... We found last February that the error-case tests added by commit 008cf0409 failed on OpenBSD, because that platform doesn't really check locale names. At the time it seemed that that was only an issue for LC_CTYPE, but testing on a more recent version of OpenBSD shows that it's now equally lax about LC_COLLATE. Rather than dropping the LC_COLLATE test too, put back LC_CTYPE (reverting c4b0edb07), and adjust these tests to accept the different error message that we get if setlocale() doesn't reject a bogus locale name. The point of these tests is not really what the backend does with the locale name, but to show that createdb quotes funny locale names safely; so we're not losing test reliability this way. Back-patch as appropriate. Discussion: https://postgr.es/m/231373.1610058324@sss.pgh.pa.us	5 years ago

Michael Paquier	008cf04096	createdb: Fix quoting of --encoding, --lc-ctype and --lc-collate ... The original coding failed to properly quote those arguments, leading to failures when using quotes in the values used. As the quoting can be encoding-sensitive, the connection to the backend needs to be taken before applying the correct quoting.

Alvaro Herrera	1caef31d9e	Refactor Perl test code ... 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.

Tom Lane	c67a86f7da	Fix TAP tests to use only standard command-line argument ordering. ... Some of the TAP tests were supposing that PG programs would accept switches after non-switch arguments on their command lines. While GNU getopt_long() does allow that, our own implementation does not, and it's nowhere suggested in our documentation that such cases should work. Adjust the tests to use only the documented syntax. Back-patch to 9.4, since without this the TAP tests fail when run with src/port's getopt_long() implementation. Michael Paquier	11 years ago
