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

Andres Freund	229f8c219f	tap tests: replace 'master' with 'primary'. ... We've largely replaced master with primary in docs etc, but tap test still widely used master.

Tom Lane	5cbfce562f	Initial pgindent and pgperltidy run for v13. ... Includes some manual cleanup of places that pgindent messed up, most of which weren't per project style anyway. Notably, it seems some people didn't absorb the style rules of commit c9d297751, because there were a bunch of new occurrences of function calls with a newline just after the left paren, all with faulty expectations about how the rest of the call would get indented.	5 years ago
Robert Haas	dbc60c5593	Rename pg_validatebackup to pg_verifybackup. ... Also, use "verify" rather than "validate" to refer to the process being undertaken here. Per discussion, that is a more appropriate term.

Robert Haas	0d8c9c1210	Generate backup manifests for base backups, and validate them. ... A manifest is a JSON document which includes (1) the file name, size, last modification time, and an optional checksum for each file backed up, (2) timelines and LSNs for whatever WAL will need to be replayed to make the backup consistent, and (3) a checksum for the manifest itself. By default, we use CRC-32C when checksumming data files, because we are trying to detect corruption and user error, not foil an adversary. However, pg_basebackup and the server-side BASE_BACKUP command now have options to select a different algorithm, so users wanting a cryptographic hash function can select SHA-224, SHA-256, SHA-384, or SHA-512. Users not wanting file checksums at all can disable them, or disable generating of the backup manifest altogether. Using a cryptographic hash function in place of CRC-32C consumes significantly more CPU cycles, which may slow down backups in some cases. A new tool called pg_validatebackup can validate a backup against the manifest. If no checksums are present, it can still check that the right files exist and that they have the expected sizes. If checksums are present, it can also verify that each file has the expected checksum. Additionally, it calls pg_waldump to verify that the expected WAL files are present and parseable. Only plain format backups can be validated directly, but tar format backups can be validated after extracting them.
