It seems better to use TEST_PATH in combination with a constant string rather than have a number of different path constants. This improves readability and reduces confusion about which constant should be used.
For tests already updated as part of the macro-replacement effort, the output tests (TEST_ERROR, TEST_RESULT_LOG, TEST_STORAGE_LIST and TEST_RESULT_STR) have been simplified for readability to remove all but the TEST_PATH constants. The ongoing macro-replacement effort will include these changes.
Updated: expireTest, stanzaTest, checkTest, infoTest, verifyTest (infoArchive and infoBackup had no changes).
HRN_CFG_LOAD() handles the majority of test configuration loads and has various options for special cases.
It was not clear when to use harnessCfgLoadRaw() vs harnessCfgLoad(). Now "raw" functionality is granular and enabled by parameters, e.g. noStd.
A define was already added for TEST_PATH but it was not widely used. Replace all occurrences of testPath() with TEST_PATH in the tests.
Replace testUser() with TEST_USER, testGroup() with TEST_GROUP, testRepoPath() with HRN_PATH_REPO, testDataPath() with HRN_PATH, testProjectExe() with TEST_PROJECT_EXE, and testScale() with TEST_SCALE.
Replace {[path]}, {[user]}, {[group]}, etc. with defines and remove hrnReplaceKey(). This is better than having two ways to deal with replacements.
In some cases the original test*() getters were kept because they are used by the harness, which does not have access to the new defines. Move them to harnessTest.intern.h to indicate that the tests should no longer use them.
Replace all instances of strNew("") with strNew() and use strNewZ() for non-empty zero-terminated strings. Besides saving a useless parameter, this will allow smarter memory allocation in a future commit by signaling intent, in general, to append or not.
In the tests use STRDEF() or VARSTRDEF() where more appropriate rather than blindly replacing with strNewZ(). Also replace strLstAdd() with strLstAddZ() where appropriate for the same reason.
Some version interface test functions were integrated into the core code because they relied on the PostgreSQL versioned interface. Even though they were compiled out for production builds they cluttered the core code and made it harder to determine what was required by core.
Create a PostgreSQL version interface in a test harness to contain these functions. This does require some duplication but the cleaner core code seems a good tradeoff. It is possible for some of this code to be auto-generated but since it is only updated once per year the matter is not pressing.
When the FUNCTION_*_RESULT*() macros were renamed to FUNCTION_*_RETURN_*() in the core code the test harness macros were missed.
Update them to make the naming consistent.
Multi-repository implementations for the archive-push, check, info, stanza-create, stanza-upgrade, and stanza-delete commands.
Multi-repo configuration is disabled so there should be no behavioral changes between these commands and their current single-repo implementations.
Multi-repo documentation and integration tests are still in the multi-repo development branch. All unit tests work as multi-repo since they are able to bypass the configuration restrictions.
There were a number of places in the code where "hostId" was used, but hostId is just the option group index + 1 so this led to a lot of +1 and -1 to convert the id to an index and vice versa.
Instead just use the zero based index wherever possible. This is pretty much everywhere except when the host-id option is read or set, or where a message is being formatted for the user.
Also fix a bug in protocolRemoteParam() where remotes spawned from the main process could get process ids that were not 0. Only the locals should spawn remotes with process id > 0. This seems to have been harmless since the process id is only a label, but it could be confusing when debugging.
These constants don't scale well as the index total is increased for an option.
The core code rarely uses these options and they are easily replaced with cfgOptionName().
The tests had started to make use of the constants, so provide functions that build the option name from the optionId and, optionally, the optionKey.
Previously, catalog versions were fixed for all versions which made maintaining the catalog versions during PostgreSQL beta and release candidate cycles very painful. A version of pgBackRest which was functionally compatible was rendered useless by a catalog version bump in PostgreSQL.
Instead use only the control version to identify a PostgreSQL version when possible. Some older versions require a catalog version to positively identify a PostgreSQL version, so include them when required.
Since the catalog number is required to work with tablespaces it will need to be stored. There's already a copy of it in backup.info so use that (even though we have been ignoring it in the C versions).
If a stop command has been issued the check command fails due to archiving timing out.
Provide a hint to document this situation and point the user in the proper direction.
We use the Z suffix in many functions to indicate that we are expecting a zero-terminated string so make this function conform to the pattern.
As a bonus the new name is a bit shorter, which is a good quality in a commonly-used function.
An upcoming feature requires new parameters for storagePosixNew() and this causes a lot of churn because almost every test creates a Posix storage object. Some refactoring in the tests might reduce this duplication but storagePosixNew() is collecting a lot of parameters so converting to storagePosixNewP() makes sense in any case.
There are relatively few call sites in the core code but they still benefit from better readability after this change.
When pgbackrest was present this test behaved unexpectedly.
While the binary is not currently required for this test is might be in the future so fix the test to prevent a regression.
Pq script errors are now printed in test output in case they are being masked by a later error.
Once a script error occurs, the same error will be thrown forever rather than throwing a new error on the next item in the script.
HRNPQ_MACRO_CLOSE() is not required in scripts unless harnessPqScriptStrictSet(true) is called. Most higher-level tests should not need to run in strict mode.
The command/check test seems to require strict mode but there's no apparent reason why it should. This would be a good thing to look into at some point.
Adding a dummy column which is always set by the P() macro allows a single macro to be used for parameters or no parameters without violating C's prohibition on the {} initializer.
-Wmissing-field-initializers remains disabled because it still gives wildly different results between versions of gcc.
Note that building the manifest on each host has been temporarily removed.
This feature will likely be brought back as a non-default option (after the manifest code has been fully migrated to C) since it can be fairly expensive.
Three major changes were required to get this working:
1) Provide the path to pgbackrest in the build directory when running outside a container. Tests in a container will continue to install and run against /usr/bin/pgbackrest.
1) Set a per-test lock path so tests don't conflict on the default /tmp/pgbackrest path. Also set a per-test log-path while we are at it.
2) Use localhost instead of a custom host for TLS test connections. Tests in containers will continue to update /etc/hosts and use the custom host.
Add infrastructure and update harnessCfgLoad*() to get the correct exe and paths loaded for testing.
Since new tests are required to verify that running outside a container works, also rework the tests in Travis CI to provide coverage within a reasonable amount of time. Mainly, break up to doc tests by VM and run an abbreviated unit test suite on co6 and co7.
Checking the PostgreSQL-reported path and version against the pgBackRest configuration helps ensure that pgBackRest is operating against the correct cluster.
In Perl this functionality was in the Db object, but check seems like a better place for it in C.

Implement switch WAL and archive check in C but leave the rest in Perl for now.
The main idea was to have some real integration tests for the new database code so the rest of the migration can wait.
