Daniel Gustafsson	7dac61402e	Remove unused module imports from TAP tests ... The Config and Cwd modules were no longer used, but remained imported, in a number of tests. Remove to keep the imports to the actually used modules. Reviewed-by: Andrew Dunstan <andrew@dunslane.net> Discussion: https://postgr.es/m/A5A074CD-3198-492B-BE5E-7961EFC3733F@yesql.se	4 years ago
Noah Misch	f2698ea02c	Introduce PG_TEST_TIMEOUT_DEFAULT for TAP suite non-elapsing timeouts. ... Slow hosts may avoid load-induced, spurious failures by setting environment variable PG_TEST_TIMEOUT_DEFAULT to some number of seconds greater than 180. Developers may see faster failures by setting that environment variable to some lesser number of seconds. In tests, write $PostgreSQL::Test::Utils::timeout_default wherever the convention has been to write 180. This change raises the default for some briefer timeouts. Back-patch to v10 (all supported versions). Discussion: https://postgr.es/m/20220218052842.GA3627003@rfd.leadboat.com	4 years ago
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.

Tom Lane	7f580aa5d8	Improve contrib/amcheck's tests for CREATE INDEX CONCURRENTLY. ... Commits fdd965d07 and 3cd9c3b92 tested CREATE INDEX CONCURRENTLY by launching two separate pgbench runs concurrently. This was needed so that only a single client thread would run CREATE INDEX CONCURRENTLY, avoiding deadlock between two CICs. However, there's a better way, which is to use an advisory lock to prevent concurrent CICs. That's better in part because the test code is shorter and more readable, but mostly because it automatically scales things to launch an appropriate number of CICs relative to the number of INSERT transactions. As committed, typically half to three-quarters of the CIC transactions were pointless because the INSERT transactions had already stopped. In passing, remove background_pgbench, which was added to support these tests and isn't needed anymore. We can always put it back if we find a use for it later. Back-patch to v12; older pgbench versions lack the conditional-execution features needed for this method.

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.

Noah Misch	fdd965d074	Avoid race in RelationBuildDesc() affecting CREATE INDEX CONCURRENTLY. ... CIC and REINDEX CONCURRENTLY assume backends see their catalog changes no later than each backend's next transaction start. That failed to hold when a backend absorbed a relevant invalidation in the middle of running RelationBuildDesc() on the CIC index. Queries that use the resulting index can silently fail to find rows. Fix this for future index builds by making RelationBuildDesc() loop until it finishes without accepting a relevant invalidation. It may be necessary to reindex to recover from past occurrences; REINDEX CONCURRENTLY suffices. Back-patch to 9.6 (all supported versions).
