8766326da8 Add protocolRemoteFree() to shutdown a specific remote.
Sometimes it is useful to shutdown remotes that are no longer needed instead of waiting for them to be shutdown at program exit.

35a262951a Pq test harness usability and error reporting improvements.
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.

d6479ddd0e Add log replacements to help test non-deterministic log output.
Some log output (e.g. time) is hard to test because the values can change between tests.

Add expressions to replace substrings in the log with predictable values to simplify testing.

This is similar to the log replacement facility available for Perl expect log testing.

e4716ee036 Improve diff output in tests.
Always compare expected vs actual (in that order) and give a hint in the error message to indicate what should be added and what removed.

8c47ee296a Improve storage harness test callback.
Add ability to omit the root (i.e. dot) path and get real size of compressed files.

1b3770e248 Recopy during backup when resumed file is missing or corrupt.
A recopy would occur if the size or checksum was invalid but on error the backup would terminate.

Instead, recopy the resumed file on any error.  If the error is systemic (e.g. network failure) then it should show up again during the recopy.

d3f717c892 Storage hardlink and symlink features require path feature.
Since there is only one driver that supports (or is likely to support) links (Posix), require the path feature to make logic in the code simpler.

The checks are added just in case another driver supports links.

e632c60525 Fix backup labels in mock/all resume integration tests.
These were not getting updated to match the directory name when the manifests were copied.

The Perl code didn't care but the C code expects labels to be set correctly.

5395aa0c92 Allocate one extra process for backup from standby.
The connection to the primary is process-max + 1 so make space for it.

b2d82bd248 Add functions to get the substring found by regExpMatch().
For now this is only used in testing but there are places where it could be useful in the core code.

Even if that turns out not to be true, it doesn't seem worth implementing a new version in testing just to capture a few values that we already have.

053af2f54d Add asserts to ensure hostId > 0.
hostId is 1-based (e.g. pg1-*) so it should always be > 0.

8dfe0e48e2 Use more general error code when tablespace linked into PGDATA.
The specific error code was not that useful since we also test the error message which contains details of the link error.

fc291b6f28 Reduce the scope of mock/all exclusion tests.
Run exclusions only on the tests where they will have an effect to reduce churn in the expect logs when they change.

d15ed33821 Make MCV return false when a boolean tie.
This is to maintain compatibility with the older Perl code that returned the lowest sorted order item in a tie.

For other datatypes the C code returns the same value, often enough at least to not cause churn in the expect tests.

bc83354fb5 Add storage feature flags.
Even though storagePathSync() is a noop when path sync is not supported, it is useful to know in advance if the function will do anything so add the storageFeaturePathSync flag.

The storageFeatureSymLink and storageFeatureHardLink flags are currently informational only since links are not yet implemented in the storage interface.

50eb062e0e Fix reference list when backup.info is reconstructed in expire command.
Adding a manifest to backup.info was migrated to C in 4e4d1f41 but deduplication of the references was missed leading to a reference for every file being added to backup.info.

Since the backup command is still using the Perl version of reconstruct this issue will not express unless 1) there is a backup missing from backup.info and 2) the expire command is run directly instead of running after backup as usual.

This unlikely combination of events means this is probably not a problem in the field.

686b6f91da Set archive-check option in manifest correctly when offline.
Archive check does not run when in offline backup mode but the option was set to true in the manifest.  It's harmless since these options are informational only but it could cause confusion when debugging.

82df7e6f3b Update integration tests in real/all that use test points.
Test points are not supported by the new C code so these will be replaced with unit tests.

The fact that the tests still pass even when the changes aren't made mid-backup (except application_name) shows how weak they were in the first place.

Even so, this does represent a regression in (soon to be be removed) Perl coverage.

8800f32ad9 Remove exclusions once they have been tested in mock/all.
The exclusions no longer have any effect after a restore and just add noise to the expect log.

9856fef586 Update integration tests in mock/all that use test points.
Test points will not be available in the C code so update these tests as best as possible without using them.

This represents a loss of coverage for the Perl code (soon to be removed) which will be made up in the C code with unit tests.

3cd45a7411 Remove start/stop --force integration tests in mock/all.
These tests require test points which are not being implemented in the C code.

This functionality is fully tested in the command/control unit tests so integration tests are no longer required.

01aefc563d Update Perl page checksum expression.
This expression determines which files contain page checksums but it was also including the directory above the relation directories.  In a real PostgreSQL installation this not a problem because these directories don't contain any files.

However, our tests place a file in `base` which the Perl code thought should have page checksums while the new C code says no.

Update the expression to document the change and avoid churn in the expect logs later.

cace54151f Add hostId to protocolLocalGet().
Previously this function was only creating locals that talked to the repository.  Backup will need to be able to talk to multiple PostgreSQL hosts.

a4b9440d35 Only install specific lcov version when required.
Installing lcov 1.14 everywhere turned out to be a problem just as using 1.13 on Ubuntu 19.04 was.

Since we primarily use Ubuntu 18.04 for coverage testing and reporting, we definitely want to make sure that works.  So, revert to using the default packaged lcov except when specified otherwise in VmTest.pm.

PostgreSQL minor version releases are also included since all containers have been rebuilt.

52a3ba6b6f Revert "Forbid % character in parameters."
The issue "fixed" in f01aa586 was caused by treating all strings as format strings while logging, which was fixed in 0c05df45.

Revert because there no longer seems a reason for the extra logic, and it was only partially applied, i.e. not to env vars, command-line options, or config options.

381aecae4e Fix walPath() when CWD is / and path is relative.
The function would return a // prefix in this case, which works fine but looks odd while debugging.

0c05df4582 Add _FMT() logging macro variants.
Using the same macros for formatted and unformatted logging had several disadvantages.

First, the compiler was unable to verify the format string against the parameters.

Second, legitimate % characters in messages were being interpreted as format characters with garbage output ensuing.

Add _FMT() variants and update all call sites to use the correct variant.

f01aa5861d Forbid % character in parameters.
This character causes problems in C and in the shell if we try to output it in an error message.

Forbid it completely and spell it out in error messages to avoid strange effects.

There is likely a better way deal with the issue but this will do for now.

6be9c7b63a Don't log secrets in cipherBlock module.
In practice there are lots of ways secrets can be leaked (e.g. info load, protocol) but at least remove this instance.

c524ec4f95 Remove obsolete integration tests from mock/all.
The protocol timeout tests have been superceded by unit tests.

The TEST_BACKUP_RESUME test point was incorrectly included into a number of tests, probably a copy pasto.  It didn't hurt anything but it did add 200ms to each test where it appeared.

Catalog and control version tests were redundant.  The database version and system id tests covered the important code paths and the C code gets these values from a lookup table.

Finally, fix an incomplete update to the backup.info file while munging for tests.

53cd530bbf Safely initialize manifest object.
Using a designated initializer is safer than zeroing the struct.  It is also better for debugging because Valgrind should be able to detect access to areas that are not initialized due to alignment.
