concurrencytest

Overview ¶

Package concurrencytest is a test package that postgres's multi-process template tests compile and run as separate processes. Each process ensures the same template, clones from it in parallel subtests, and releases it. It has no non-test code of its own.

Environment variables set by the driver tests:

TESTDB_CONC_TEMPLATE     template name to share (default: a standalone name)
TESTDB_CONC_FINGERPRINT  fingerprint passed to WithFingerprint, if set
TESTDB_CONC_SETUP_LOG    file to append a line to each time setup runs
TESTDB_CONC_READY_FILE   file to create once EnsureTemplate has returned
TESTDB_CONC_HOLD         duration to sleep before running tests, so the
                         driver can kill the process while it holds the
                         template
