Bug Fixes:
* Fix archive-push/archive-get when PGDATA is symlinked. These commands tried to use cwd() as PGDATA but this would disagree with the path configured in pgBackRest if PGDATA was symlinked. If cwd() does not match the pgBackRest path then chdir() to the path and make sure the next cwd() matches the result from the first call. (Reported by Stephen Frost, Milosz Suchy.)
* Fix reference list when backup.info is reconstructed in expire command. 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.
* Fix segfault on unexpected EOF in gzip decompression. (Reported by Stephen Frost.)
The TZ environment variable was not reliably pushed down to the test processes.
Instead pass TZ via a command line parameter and set explicitly in the test process.
Using gmtime() produced output skewed by the local timezone.
Since this function is currently only used for debug logging this is not a live bug in the field.
Commit 7168e074 tried to use cwd() as PGDATA but this would disagree with the path configured in pgBackRest if PGDATA was symlinked.
If cwd() does not match the pgBackRest path then chdir() to the path and make sure the next cwd() matches the result from the first call.
If the compressed stream terminated early then the decompression process would get a flush request (NULL input buffer) since the filter was not marked as done. This could happen on a zero-length or truncated (i.e. invalid) compressed file.
Change the existing assertion to an error to catch this condition in production gracefully.
82df7e6f and 9856fef5 updated tests that used test points in preparation for the feature not being available in the C code.
Since tests points are no longer used remove the infrastructure.
Also remove one stray --test option in mock/all that was essentially a noop but no longer works now that the option has been removed.
This module will eventually contain various useful zero-terminated string functions.
For now, using NULL_Z instead of strPtr(NULL_STR) avoids a strict aliasing warning on RHEL 6. This is likely a compiler issue, but adding these constants seems like a good idea anyway and we are not going to get a fix in a gcc that old.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
